SIR, By your Majesty’s most gracious permission, I have the honour to present to your Majesty the Domestic History of the Inventor of Logarithms. That his invention was the greatest boon genius could bestow upon a Maritime Empire is a truth universally felt, and which no person is better qualified to appreciate than your Majesty. It is a proud reflection for Britain, that she does not owe to a stranger the creation of that intellectual aid which renders your Majesty’s Fleets as free and fearless in Navigation as they have ever been in Battle. To such considerations alone am I entitled to attribute your Ma- jesty’s condescension in accepting of this work. I have the honour to remain, Your Majesty’s humble and devoted Subject and Servant, MARK NAPIER. 5 FL1LE 7 | fie yw bane thot « -, 2 y? io ADEE ini ‘aD gf coubin ah dix oe wiobcery. dhol ted shed ysl Cal Tue illustrious Philosopher whose domestic history is now, for the first time, fully recorded, left many private papers besides voluminous parchments. His personal manuscripts, of course chiefly scientific, came into the possession of his third son, Ro- bert Napier of Bowhopple, Culcreugh, and Drumquhannie, who edited his father’s posthumous works. The late Colonel Milliken Napier, Robert’s lineal male representative, was still in possession of a mass of the Culcreugh papers at the close of last cen- tury. The Colonel was no antiquary, and, like most of the de- scendants of the great Napier, chiefly evinced his philosophy in a supreme indifference to sabre and gun-shot wounds, in the service of his country, which were liberally bestowed upon him during twenty-two years of a military career in every quarter of the globe. His excellent lady, from whom I have the following fact, upon one oc- casion, before accompanying her husband from home, deposited the venerable relics of the Philosopher, including a portrait of him, and a Bible with his autograph, in a chest which was placed for safety in a garret of their house of Milliken in Renfrewshire. During their absence the house was burnt, and the precious deposit perished. It is to be regretted that the present attempt had not been made vi PREFACE. before this dilapidation of the materials occurred. Still, however, much remained which it was desirable to rescue from the chapter of accidents. In particular, two manuscript treatises, one upon Arithmetic, and the other upon Algebra, composed by Napier, had been previously presented to Francis V Lord Napier, by William Napier, fifth of Culcreugh, and thus escaped the destruction of the other papers. The late Lord (Francis VII.) saved these manu- scripts from decay, very obviously commencing, and he notes upon a blank leaf, “ finding them in a neglected state amongst my family papers, I have bound them together, in order to preserve them en- tire.’ The reason of this remnant having passed to the noble branch of the family is manifest. Francis V Lord Napier, a most accomplished nobleman, (who in the year 1761 procured, at his own expense, a survey, plan, and estimate for a navigable canal to form a communication between the rivers Forth and Clyde, and which idea was subsequently carried into execution upon a great scale,) had turned his elegant and comprehensive mind towards the composition of a biographical work worthy of the memory of his great ancestor. The fact is curiously recorded. Sir Alexander Johnston, late Chief-Justice of Ceylon, and now of his Majesty’s Privy-Council, was examined before the committee on the affairs of the East India Company in July 1832, when he gave some inte- resting evidence relating to the Hindoo governments. The follow- ing extract from that evidence will inform the reader of the unex- pected termination of Lord Napier’s literary project: “ Were you acquainted, while in Ceylon, with the late Colonel C. Mackenzie, the Surveyor-General of all India, and with the collection which he made of materials for writing a history of India? I was intimately acquainted with him from my earliest youth, and I was in constant communication with him all the time I was in Ceylon, from 1802 to 1818, upon subjects connected with the history of India and of that island, and had frequent occasion to refer for information to his valuable collection of ancient inscriptions and historical documents. PREFACE. vii Be so good as to explain the circumstances which first led Colonel Mackenzie to make this collection, and those which led the Bengal government after his death to purchase it from his widow ? Colo- nel Mackenzie was a native of the island of Lewis ; as a very young man, he was much patronized, on account of his mathematical knowledge, by the late Lord Seaforth, and my late father, Francis, the fifth Lord Napier of Merchiston. He was for some time em- ployed by the latter, who was about to write a life of his ancestor, John Napier of Merchiston, the Inventor of Logarithms, to collect for him, with a view to that life, from all the different works rela- tive to India, an account of the knowledge which the Hindoos possessed of mathematics, and of the nature and use of Lo- garithms. Mr Mackenzie, after the death of Lord Napier, be- came desirous of prosecuting his oriental researches in India. Lord Seaforth got him appointed to the engineers on the Ma- dras establishment in 1782, and gave him letters of introduction to the late Lord Macartney, the then Governor of that Presi- dency, and to my father, who held a high situation under his Lordship at Madura, the ancient capital of the Hindoo kingdom, described by Ptolemy as the regio Pandionis of the peninsula of India, and the ancient seat of the Hindoo college. My mother, who was the daughter of Mr Mackenzie’s friend and early patron, the fifth Lord Napier, and who, in consequence of her father’s death, had determined herself to execute the plan which he had founded of writing the life of the Inventor of Logarithms, resided at that time with my father at Madura, and employed the most distinguished of the Brahmins in the neighbourhood in collecting for her from every part of the peninsula the information which she required relative to the knowledge which the Hindoos had. posses- sed in ancient times of mathematics and astronomy. Knowing that Mr Mackenzie had been previously employed by her father in pur- suing the literary inquiries in which she herself was then engaged, and wishing to have his assistance in arranging the materials which Vill PREFACE. she had collected, she and my father invited him to come and live with them at Madura early in 1783, and there introduced him to all the Brahmins and other literary natives who resided at that place.” No life of Napier, however, was destined to result from these spirited proceedings, which gave rise to the celebrated Mac- kenzie Collection ; and, Sir Alexander adds in his evidence, “ the Marquis of Hastings purchased the whole collection for the Kast India Company from Colonel Mackenzie’s widow for L. 10,000, and thereby preserved for the British Government the most valu- able materials which could be procured for writing an authentic history of the British empire in India.” Unfortunately the papers of the Honourable Mrs Johnston were also consumed by fire, an element that has been severe upon the materials for our Philosopher’s biography. The late Earl of Buchan, towards the close of last cen- tury, put together a few quarto pages of meagre and inaccurate bio- graphy, which he called the Life of Napier, and to this was added an able but dry analysis of his published mathematical inventions by Dr Minto. This work has done more harm than good to the sub- ject, as, from its imposing shape and title, it has given rise to a vague impression that nothing further could be known or said about Na- pier, and may have deterred others, better qualified for the task than I can pretend to be, from exerting themselves to do justice to his memory. The late Lord Napier compiled with great pains and accuracy a digest of his charters and private papers, composing a genealogical account of his family, which remains in manuscript. ‘This his Lord- ship communicated to Mr Wood, and the substance of it will be found in the account of the family of Napier contained in that gentleman’s edition of Douglas’s Peerage. From that source chiefly the slight biographical notices of the philosopher, lately published, are derived. Still his very curious mathematical manuscripts re- mained unexamined, and some of the most interesting and charac- teristic particulars of his history unrecorded. PREFACE. ix The present Lord Napier having allowed me unlimited access to his family papers, and encouraged me throughout this undertaking with his kind and intelligent co-operation, I have done my best to supply the desideratum. In some respects a philosopher would have been the most proper biographer of Napier, particularly in the analysis of his unpublished treatises, to which I can scarcely hope to have done justice beyond the fact of making their contents known. But there were antiquarian difficulties to encounter, both in mas- tering the contents of his manuscripts, and in the other researches upon which these Memoirs are founded, to which mathematicians are little inclined. ‘The world had waited long enough for a scien- tific life of Napier, and while the Logarithms, most amply and ad- mirably commented upon by illustrious foreigners, were continually adding glory to the land of their birth, the very knowledge of who invented them seemed to be escaping from the popular literature of his own country. My object has been not only to record every fact of interest regarding the great Napier, but to exhibit a pic- ture of him relieved upon the dark ground of his times,—to con- nect him with the political and religious history of his country, no less than with the history of science. It is a curious fact, and affords one of several instances in which the memory of our Philosopher has been strangely neglected, that no portrait of him has been engraved in Mr Lodge’s Portraits of [- lustrious Personages of Great Britain. Bacon is there, and New- ton, but not Napier. Yet that brilliant publication includes John Knox, though the engraving, meant to represent him, is taken from an old anonymous portrait in Holyroodhouse, certainly not of John Knox, holding a pair of compasses over a chart. A most authentic portrait of Napier, however, and in excellent preservation, belongs to the College of Edinburgh. The record of donations to that University proves that it was presented by Margaret, Baroness of Napier in her own right, to whom the honours opened in 1686. There can be no doubt of its originality. It bears the shield of b PREFACE. x arms and the initials of the philosopher with the date 1616, the year before his death ; and also his age, 67, all of which are ob- viously contemporary with the rest of the painting. It has been partially engraved for this work, including a sketch, however, of all the minor details. Who painted it is a difficult question, as the date is prior to the era of Jamieson, and during a very rude age of portrait painting in Scotland. Yet, though defective in perspective, it is well coloured, and altogether a noble portrait. I have chosen it for this work in preference to another, unquestionably original, of the same size, belonging to Lord Napier, and which has never been out of the family. But his Lordship’s is not in such good preservation, and, though quaint and interesting, is a ruder specimen of art. The countenances are very similar, but the paintings quite different. They are seated in different chairs, and in a different dress and attitude. The upper part of the figure in Lord Napier’s is clothed in a close tunic of black, with a black cowl concealing the hair and half of the brow. The lower part of the figure seems enveloped in drapery, and the left hand holds a book at a table. An etching of it was intended to illustrate this preface, and also one from a dilapidated portrait, in Lord Napier’s gallery, of the Philosopher’s first wife; these etchings, accordingly, are alluded to in the Memoirs, but have not been inserted, as the details of the old paintings were doubtfully made out. Mr Napier of Blackstone possesses a half-length portrait of the Philosopher with the cowl, which has very much the air of an original. The same may be said of one in possession of Aytoun of Inchdernie, whose ancestor was connected by marriage with the family of Merchiston. This also has the cowl. The late Lord Napier acquired a very original- looking half-length of him without the cowl, the history of which I cannot trace. ‘There is another of the same size with the cowl, be- longing tooneof the law professors in Edinburgh, which I have heard called an original of the Baron from the pencil of Jamieson. This would be an exceedingly interesting portrait. But could the Scot- PREFACE. xi tish Vandyke have painted any portrait in Scotland until some years after the Philosopher’s death ? Unquestionably he painted the first Lord Napier. ‘This portrait, of which an engraving is given in the Memoirs, is included in the catalogue of Jamieson’s works, and is still in possession of Lord Napier. An original of the great Napier by the same master would scarcely have been suffered to wander out of the family.* Jamieson, however, may have copied some of these heads of the Philosopher when he painted his son. The en- graving of Mary Queen of Scots will be contemplated with great interest. Among the various portraits of her, with more or less claims to originality, none possess higher than this, though never until now publickly noticed. It is not a copy from any other known, and all the characteristics are in favour of its perfect originality. Upon the back of it there is, in the hand-writ- ing of the late Lord Napier, “ This picture of Mary Queen of Scots, supposed to be painted when she was about twelve years old, has ever been considered an original picture, and has been in the possession of the family of Napier for many generations. Mr David Martin, at the desire of Lord Napier, stretched it on new * A biographical notice of our Philosopher, contained in the Library of Entertaining Know- ledge, 1830, is at great pains to state that he was not Lord Napier; but, adds a note, hitherto un- contradicted, which has a much greater tendency to confuse his genealogy, “ Professor Napier of Edinburgh, who is descended from Lord Napier, is in possession of the set of bones used by his great ancestor.” —Vol. viii. p. 56. I would not have noticed a capricious adoption of the sur- name of Napier by the Professor of Scots Law Conveyancing in Edinburgh, (also editor of the Encyclopedia Britannica,) whose proper surname is Macvey, were it not that the publication and wide diffusion of the genealogical error quoted above might impress, foreigners at least, with the notion that a scion of Merchiston, perhaps the philosopher’s representative, occupies a learned chair in the University of Edinburgh. A very minute acquaintance with the history of Napier, in all its branches, does not enable me to record the most distant genealogical connec- tion between the family of Napier of Merchiston and any one of the name of Macvey ; or, however honoured the Napier tree might be by the acquisition, that it is possible that the Professor can be descended from any Lord Napier. Lord Napier possesses a very primitive set of those ingeni- ous instruments of calculation “ Neper’s Bones,” but framed of card disposed upon rollers in an oaken box, the figures upon which appear to be in the handwriting of the philosopher or his son Robert. Like the wood of the true cross, however, the identical original bones may have been scattered far, and infinitely multiplied. xii PREFACE. canvass and cleaned it 1787.” It will be seen that there were many channels through which such a relic might reach the family of Mer- chiston. The likeness is perfectly preserved in the engraving, which, however, cannot convey the delicate and youthful complexion, Dr Robertson says, “ Her hair was black—her eyes were a dark-grey ;” and had this been written in any other spirit than that of romance, it would contradict the authenticity of Lord Napier’s picture, where the hair is yellow, and the eyes of a decided hazel or chesnut-colour. But Sir James Melville says expressly, that her complexion was fair ; and “ Beal, the clerk of the Privy-Council, who was directed by Ce- cil to see and report the death of the Scottish Queen, describes her as having chesnut-coloured eyes.’— Chalmers. The autograph at- tached is taken from an original letter of the young Queen (when about the age represented in this portrait) to her mother, preserved in the Register-House. The Portrait of Dr Napier, the warlock of Oxford, is exceedingly characteristic. There can be no doubt that he and the Philosopher were brothers’ children, that fact being re- corded by the first Lord Napier, who could not be mistaken as to the family of his own granduncle. I had intended to have given a complete statement, in the Ap- pendix, of the Lennox Case for Merchiston, proving the Philosopher’s, and consequently Lord Napier’s, right to that ancient Earldom ; but having occupied more space with the abstract of Napier’s Alge- bra than I had anticipated, the Case, with genealogical trees of the family, &c., is reserved for publication in another shape. I have retained, however, so much of it as may suffice to meet certain er- rors that have crept into the history of Scotland. August 1834. CONTENTS. CHAPTER I.

LIFE OF JOHN NAPIER OF MERCHISTON. CHAPTER LI. THAT the life of a philosopher affords few incidents for his biography, is remarked in every attempt to satisfy the curiosity of the world as to the do- mestic habits of such men. Even with regard to Sir Isaac Newton, who lived in an age and country the ameliorated state of which had multiplied social relations, a regret has been expressed, that he must be constantly viewed in connection with the progress of science, and scarcely ever in communion with human nature. _ If this be true of Newton, how much more so is it of him whom the com- mon people of his day used to designate by the mysterious epithet of the “ Marvellous Merchiston,’—who was born a century before the English phi- losopher, in the most savage age of a barbarous land, where betwixt himself and contemporary barons, much the same sympathies existed that Daniel en- joyed in the lion’s den. There is this advantage, however, in the antiquity of the present subject, that slight notices become valuable, particularly if they involve picturesque relations to the history of the country. I do not despair of being able to sa- tisfy the reader’s curiosity as to the private life and habits of our great phi- losopher, more fully than he may have anticipated. But this it is hoped, will also add something to the interest, that the lineage which Napier represent- A 4 THE LIFE OF ed, and the relatives among whom he was reared, connect in a remarkable manner with the annals of Scotland. It may be said that his biography can be neither more nor less than a chapter of human knowledge in its loftiest departments; and it is usual to dismiss the mortal genealogies of the sons of science with almost contemp- tuous brevity. But the pride of intellect which affects a supercilious disdain for an historical lineage or hereditary honour, if less absurd, is perhaps more mischievous than the pride of ancestry. Applied to the history of philoso- phers the proposition seems questionable, that it is “ more honourable to have achieved fame and eminence without the advantages of high birth, than with their assistance.” * Necessity is the mother of invention, and poverty has been found the most faithful nurse of genius. Napier incurred a greater risk of never attaining his throne in letters, from the wealth of his family, and the courtly and historical connections of his house, than if his parentage could only have been traced to a hovel. Jamus was reared as a shepherd, Ben Jonson as a bricklayer, Longomontanus was the son of a labourer, Metastasio of a common mechanic, Hadyn’s father was a wheelwright, Linneus was bred a shoemaker, and the fiery spark of Franklin’s genius was struck from the forge of a blacksmith. Without multiplying examples, or taking any from our own country, where the instances are too modern to be within the pale of courteous observation, it may be safely said, that the annals of letters are gorged with illustrious proofs that the sons of the lowly may become the lights of the world. Yet the illustrious transatlantic philosopher whom we have named, while expressing exultation in his victory over the difficulties of an inferior origin, evinces at the same time an aristocratic anxiety to surround the smithy of his ancestors with the halo of antiquity and hereditary right. ‘“ From the bosom of poverty and obscurity,” says he, in a letter of autobiography to his son, “ in which I drew my first breath and spent my earliest years, I have raised myself to a state of opulence, and to some degree of celebrity in the world.” Then he adds, “ one of my uncles, desirous like myself of collecting anecdotes of our family, gave me some notes, from which I have derived many particulars respecting our ancestors. Krom these I learn, that they had lived in the same village, (Eaton in Northamptonshire,) upon a freehold of about thirty acres, for * The Pursuit of Knowledge under Difficulties, published by the Society for the Diffusion of Knowledge. 3 NAPIER OF MERCHISTON. 3 the space at least of three hundred years. How long they had resided there prior to that period, my uncle had been unable to discover,—probably ever since the institution of surnames, when they took the appellation of Franklin, which had formerly been the name of a particular order of individuals. This petty estate would not have sufficed for their subsistence had they not added the trade of a blacksmith, which was perpetuated in the family down to my uncle’s time, the eldest son having been uniformly brought up to this employment,— a custom which both he and my father observed with respect to their eldest sons. In the researches I made at Eaton, I found no account of their births, marriages, and deaths, earlier than the year 1555; the parish register not ex- tending farther back than that period. ‘This register informed me that I was the youngest of the youngest branch of the family, counting five genera- tions,” &c. But in the British isles at least, the cottage school of knowledge is not un- rivalled ; nor can it be said, that with us genius only flashes, like the light- ning, from the bosom of obscurity. While such names as Bacon, Boyle, and Byron, illustrate the aristocracy of England and Ireland, those of Napier and Scott belong to the feudal history of their country. * The magnitude of these examples outweighs the multitude opposed ; and the contemplation is consola- tory and wholesome to the higher classes of society. The instance of Napier is peculiarly striking. In his own country, where he has no monument but his works, he as far excels all her philosophers in a comparison of intellectual achievement, as in the curious and quaint anti- quities of his race ; and of him it is that England’s greatest historian has re- corded an estimate, true to this hour, that he was “ the person to whom the * T have not instanced Sir Isaac Newton, because his mighty name belongs to the debateable land in this question. According to his latest biography, neither England nor Scotland, the aris- tocracy nor the people, can positively claim him. Sir David Brewster, after stating the pros and cons on the subject, adds, “ all these circumstances prove that Sir Isaac Newton could not trace his pedigree with any certainty beyond his grandfather ; and that there were two different tradi- tions in his family,—one which referred his descent to John Newton of Westby, and the other toa gentleman of East Lothian, who accompanied King James VI. to England. Ina letter addressed to me by the learned George Chalmers, Esq. I find the following observations respecting the imme- diate relations of Sir Isaac: ‘ The Newtons of Woolsthorpe,’ says he, ‘ who were merely yeomen farmers, were not by any means opulent. The son of Sir Isaac’s father’s brother was a carpenter called John,’ ” &c.—Brewster’s Life of Newton. A THE LIFE OF title of a GREAT MAN is more justly due than to any other whom his country ever produced.” * To verify this eulogy—which, since the career of one whose glory is so bright upon his recent grave might be thought no longer due—is the chief ob- ject of the following Memorials. In the first place, however, we must indulge in achapter or two of historical reminiscences of the descent of our great phi- losopher, and the family connections in the midst of whom his own quiet pro- gress to maturity and fame was completed. Nor is this to gratify a local vanity, or the mere lovers of genealogy. Two of the brightest stars in the galaxy of France have turned with disappointment from the difficulty of ob- taining even the miserable records which this country affords of its greatest phi- losopher. “ On connait peu de circonstances,” (says Delambre,+) “ de la vie de Neper; il était Ecossais, baron de Merchiston.”—-And Montucla,? after re- cording of his family and personal history the little he knew, which involved two errors, adds, “ Je sais qu'il y a une vie de Néper publiée, il y a peu d’an- nees a2 Edimbourg. Mais c’est en vain que j'ai tenté de me la procurer. I) est bien plus difficile d’obtenir un livre de Londres que de Petersbourg, quoi- que cette derniere ville soit six fois eloignée de nous.” John Napier was not the man to have obviated by his own researches, this dearth of information with regard to his domestic history, and we must do for him what the great American did for himself. ‘* Alexander Napare,” the first of Merchiston, acquired that estate before the year 1438, from James I. of Scotland, § was provost of Edinburgh in 1437, and otherwise distinguished in that reign. His eldest son, also Alexander, became in his father’s lifetime comptroller to James II., and ran a splendid state career under successive monarchs. But whence these Napiers came, though obviously at this early period a wealthy and distinguished family, has hitherto baffled genealogical inquiry. Peerage writers, not easily discomfited, have without any authority, boldly traced their descent from “ Johan le Naper del Counte de Dunbretan,” (one of those who swore fealty to Edward I. in 1296, and defended the Castle of * Hume’s History of England, vii. 44. t Histoire de lAstronomie Moderne, par M.

NAPIER OF MERCHISTON. 5 Stirling against that-monarch in 1304;) and thence through a variety of Wil- liam and John de Napers of feudal celebrity. After a long and arduous search through authentic records, I find there exists no authority for this genealogy. Under these circumstances, we can do no less than attend to the Legend of Merchiston, as illustrated by the truest of all records so far as it goes, the heraldic language of ancient seals. From time immemorial, that family cherished a tradition, that one of their lineal male ancestors was a younger son of a Scottish Earl of the ancient race of Levenax. In the imperfect shape in which the tradition has been transmit- ted, it must rank with those fanciful legends which compose the pleasant apo- crypha of profane history. “ The Hay of Longcarty, who bequeathed his bloody yoke to his lineage,—the dark-gray man who first founded the House of Douglas,” *—cause fastidious antiquaries to shake their heads, yet still keep their own in the romance of Scottish history. The legend of Napier is of the same description, but has been solemnly recorded in the Heralds’ books of London, owing to circumstances which, as they are not generally known, I shall narrate. James VI., of facetious memory, had no objection to enrich his coffers by an indiscriminate distribution of knighthoods and higher honours. “ Hold up thy head man, thou hast less need to be ashamed than I, sure,” was an encourag- ing exclamation of his to a shamed-faced country gentleman about to be knighted. It was a prize to him to discover in one individual the rarely com- bined qualities of wealth, good Scotch extraction, and a desire to pay for fur- ther honours with Sterling coin. Such a rara avis occurred in the person of a cadet of Merchiston in the year 1612. Robert Napier, a cousin-german of the great John, had amassed riches abroad asa merchant. At the same time the services of his fathers to the royal house, entitled him to look for honours and preferment at home. Archibald, the philosopher’s eldest son afterwards first Lord Napier, was at this time a gentleman of the bed-chamber to King James, but in no condition to purchase aggrandizement, as notwithstanding his father’s great estates in Scotland, the young laird had become involved in debt from his long attendance on the avaricious monarch.t James himself was well aware that the Napiers of Merchiston, independently of their pre- tensions to a male descent from Lennox, represented through a female a branch * Sir Walter Scott. + Original letter of Archibald Naper to Sir Julius Cesar in 1613. 6 THE LIFE OF of that earldom collateral to his own descent through Darnly.* So he knew his man, and rejoiced in the wealthy merchant, who claimed the honour of a baronetcy and was ready to pay for it. Sneers and whispers, expressive of an outraged aristocracy, went round the circle of his courtiers, who were par- ticularly jealous when the sword of honour was about to descend upon the shoulders of a Scotchman. But the king had less reason to be ashamed than usual. He attested the birth and breeding of the candidate with an oath which has become familiarly characteristic of his energetic mood. He declar- ed “ by his saul,” that the family to which Robert Napier belonged had ranked with the aristocracy for more than 300 years. William Lilly, “ the last of the astrologers,” tells this anecdote in his gossipping and graphic manner. ‘* A word or two of Dr Napper,” says he, “ who lived at great Lindford, in Buckinghamshire, was parson, and had the advowson thereof. He descended of worshipful parents, and this you must believe, for when Dr Napper’s brother, Sir Robert Napper, a Turkey merchant, was to be made a baronet in King James’ reign,} there was some dispute whether he could prove himself a gen- tleman for three or more descents. ‘ By my saul,’ saith King James, ‘ I will certify for Napper, that he is of three hundred years’ standing in his family ; all of them, by my saul, gentlemen.’” { * In “an Abstract of the Evidence adduced to prove that Sir William Stewart of Jedworth, the paternal ancestor of the present Earl of Galloway, was the second son of Sir Alexander Stewart of Darnly,” printed in London 1801, is the following observation: “ King James (VI.) was him- self descended from the family of Lennox, and was well versed in its history; for he had during his reign employed several persons to trace its genealogy. It was a subject with which he was well acquainted, and which he took particular pleasure to contemplate.” + In Sir William Dugdale’s Usage of Arms, printed at Oxford 1682, I find in his catalogue of Baronets created by James VI. November 25, 1612: “Sir Robert Naper, alias Sandy, of Lewton- How, Knight ;” and of those created by Charles II., under date March 4, 1660, “ John Napier, alias Sandy, Esq. with remainder to Alexander Napier, &c. with remainder to the heirs-male of Sir Robert Napier, Knight, grandfather to the said John; and with precedency before all baronets made since the four-and-twentieth of September, anno 10, Regis Jac., at. which time the said Sir Robert was created a baronet, which letters patent so granted to the said Sir Robert Napier were surrendered by Sir Robert Napier, (father of the said John and Alexander,) lately deceased ; to the intent that the said degree of baronet should be granted to himself, with remainder to the said John and Alexander.” It appears from Dugdale that the Turkey merchant was a knight, and of Lewton-How, before he was created a baronet in 1612. The alias of “ Sandy” was acquired from the favourite name of Alexander in the Merchiston family. { This did not escape Sir Walter Scott, who, while describing the old castle of Merchiston in his Provincial Antiquities, thus comments upon the anecdote in reference to the leaning of the NAPIER OF MERCHISTON. 7 The king’s asseveration seems to have silenced the courtiers for the time ; but in the year 1625, immediately after the demise of that monarch, and when Sir Archibald Napier was residing on his estate in Scotland, his cou- sin Sir Robert deemed it prudent to put his genealogical pretensions formally upon record in the Heralds’ books, beyond the reach of courtly cavil. He ac- cordingly applied to Merchiston, as the head of his house, for an authentic certificate of cadency; and the document with which Sir Archibald favoured him under his own hand contains the only written statement of the legend al- luded to that I can discover. It is to be regretted that King James answered so readily and lustily for the Turkey merchant ; John Napier, the philosopher, might otherwise have been applied to for this document, which would then have entered the English records in the words of the inventor of Logarithms.{ As it is, we have the tradition transmitted by him to his son, who first gave it publicity under the circumstances narrated. Sir William Segar was at the time principal king-at-arms for England. He was the very preux chevalier of heraldry, and lived amid a halo of its most brilliant recollections. In 1586, he had walked as portcullis pursuivant at the inventor of Logarithms to the occult sciences. “ It is curious to observe, that amongst the pro- fessors of astrology and other occult sciences who abounded in England in the beginning of the sixteenth century, was a Dr Napper ; this person was probably of the stock of the Scottish Na- piers,—it is possible, however, that the British Solomon tendered his evidence thus readily, be- cause his palm itched for the baronet’s fees.” Our illustrious author was not aware of the near relationship existing betwixt the great Napier and this celebrated astrological doctor, whose por- trait is still preserved at Oxford, though with a sort of longing for the fact, he ventured a conjec- ture that they belonged to the same stock. They were brothers’ sons, and I shall elsewhere have a word or two of Lilly and Dr Richard Napier. + The philosopher certainly knew the tradition, and seems to have laid some stress upon it. His commentaries on the apocalypse were translated at Rochelle; and the edition 1602 has on the title-page, “ Par Jean Napeir (c.a.d.) NompareiL, Sieur de Merchiston, reueue par lui meme.” The commendatory verses attached to his works generally turn upon the words “ nulli par,” or “impar.” The famous civilian Mranciscus Baldiunus wrote a Latin stanza upon Napier, the first couplet of which embodies the allusion,— Scotia te genuit phocis Parnassia fovit Estque impar versum nomen (Apollo) tibi. “In the year 1705, Sir Isaac Newton gave into the Heralds’ Office an elaborate pedigree, stating upon oath that he had reason to believe that John Newton of Westby, in the county of Lincoln, was his great-grandfather’s father,” &c. The pedigree was accompanied by a certificate from Sir John Newton of Thorpe, Bart——Brewster’s Life of Newton, p. 347. 8 THE LIFE OF thrilling pageantry of the state funeral of Queen Mary. He became succes- sively Somerset, Norroy, and garter herald; and in 1603, was honoured with the commission to carry the garter to Christian IV. of Denmark. In 1612, he invested the Prince of Orange with the same illustrious insignia, who pre- sented him in return with his picture set in diamonds, and a chain of gold weighing six pounds. James VI. conferred upon him the honour of knight- hood.* Such was the worthy to whom, at the request of the Turkey mer- chant, Sir Archibald Napier (by this time deputy-treasurer for Scotland, and a privy-councillor,) transmitted a curious, though very imperfect, genealogical history of the family, which Sir William recorded with the profound respect and heraldic flourishes wherein his duty and his delight at once consisted. Some account of the contents of this document. will be found in the genea- logical note at the end of the volume.+ Here it is sufficient to extract the words of Sir Archibald which refer to the Lennox origin of his house. “One of the ancient Earls of Lennox in Scotland had issue three sons; the eldest, that succeeded him to the Earldom of Lennox ; the second, whose name was Donald; and the third, named Gilchrist. The then King of Scots having wars, did convocate his lieges to battle, amongst whom that was commanded was the Earl of Lennox, who, keeping his eldest son at home, sent his two sons to serve for him with the forces that were under his command. This battle went hard with the Scots; for the enemy pressing furiously upon them, forced them to lose ground until it came to flat running away, which being perceived by Donald, he pulled his father’s standard from the bearer thereof, and valiantly encountering the foe, being well followed by the Earl of Lennox’s men, he repulsed the enemy and changed the fortune of the day, whereby a great victory was got. After the battle, as the manner is, every one drawing and setting forth his own acts, the king said unto them, ye have all done va- liantly, but there is one amongst you who hath Na-PEER; and calling Do- nald into his presence, commanded him, in regard of his worthy service and in augmentation of his honour, to change his name from Lennox to Napier, and gave him the lands of Gosford and lands in Fife, and made him his own ser- vant, which discourse is confirmed by evidences of mine wherein we are called Lennox alias Napier.” * He died in 1633, and left, as monuments of his science,—An Institute of Honour, Military and Civil, in four books, 1602.

NAPIER OF MERCHISTON. 9 This story is told, I speak with deference, rather in the historical vein of Sir Walter Scott than of Lord Hailes, and, perhaps, deserves to rank no higher in authentic history than the legends of Douglas, or Dalyell, or Hay, or For- bes.* But the Lennox descent may be true independently of the legend, “ though” (says Sir Archibald) “ this is the origin of our name, as, by tradition from father to son, we have generally, and without any doubt, received the > same ;” an assertion justified by a fact not adverted to in his own narrative, that the charter-seals of his lineal paternal ancestors, since at least the year 1400, had all proclaimed that very descent throughout an age of heraldry, and for more than two centuries before it was thus recorded in 1625. To a charter of the first Alexander Napier of Merchiston, dated in 1453, there is appended a seal bearing his name and arms in such preservation as to be distinctly read. + The device upon the shield is, in heraldic language, “a saltier engrailed, cantoned with four roses,’—a chaste and simple cogni- zance, well known to armorists as that carried by the old Earls of Levenax ; with this exception, however, (not attended to by our modern heralds and genea- logists,) that those Earls bore the saltier plain, never engrailed. * See Nisbet’s Heraldry for an account of these fanciful derivations and their legends. He has not that of Napier; but I was led to trace the history of it so far as I could, in consequence of find- ing that one of the most illustrious men of modern days, whose commentary on the Logarithms is the best and most scientific that has appeared, M. Delambre, did not disdain to advert to the le- gend in the midst of his profound speculations. “ On a varié,” says he, “sur l’orthographe du nom de Néper, qu’on a écrit Napier, et Nepair ; on croit ce dernier mot l’équivalent de peerless, sans pair, donné a l'un de ses ancétres; mais il s’est_ appelé lui-méme Neperus dans son ouvrage. Nous avons suivi l’usage constant des écrivains Francais qui écrivent Néper.”—Astronomie Moderne, p. 506, v. i. A multiplicity of original sig- natures of the great Napier occur among the family papers. His marriage settlements in 1572 are signed Jhone Neper ; the same in many other deeds down to 1610. His contract with Logan of Restalrig preserves in the signature the same orthography ; and so in a letter to his father about the close of the 16th century. But one to his son in 1608 is signed “ Jhone Nepair.” All the deeds after that date signed by him have the latter signature. His letter to James VI. prefix- ed to his theological work is signed “ John Napeir.” 1st Edit. 1593.—“Neper” is the oldest mode, His great-great-great-grandfather John, who married the heiress of Lennox, and who (mirabile dictu) could write his name in the 15th century, so spelt it. His own children, who sign deeds along with him, use every mode except Napier, which is comparatively modern. + See Note (A.) B 10 THE LIFE OF Other contemporary races of Napier, of whom the Dumbartonshire barons already mentioned are the chief, carried coat armour totally different. These were the Napiers of Kilmahew, whose estates lay in the Lennox country, and who were vassals of that earldom. But they did not assume a single bearing indicative even of the patronage of Lennox. Kilmahew is the most ancient family of the name of Napier on record in Scotland; and their armorial bear- ings were gules, on a bend azure, three crescents argent. * The Napiers of Wrightshouses, (whose antique and beautiful castle, gor- geous with heraldic carvings crowning its numerous doors and windows, was removed in the present century to make way for an hospital,} and whose an- cient line of territorial possessors has been severed from its parent stem, and cast aside by modern genealogists,) were a race quite distinct from Merchis- ton, and obviously an early branch of Kilmahew. Their armorial bearings were, 07, on a bend azure, a crescent between two mollets or spur-rowels,—the arms of Kilmahew with a slight difference. The families of Merchiston and Wrightshouses became closely connected by marriage about the epoch of the battle of Flodden Field, when Margaret, the daughter of Merchiston, married the laird of the neighbouring castle. This appears from the records of the city of Edinburgh, and the carving upon an armorial stone which once adorned a door or window of Wrightshouses, commemorative of that alliance. The stone is still preserved in an artificial ruin at Woodhouselee, and affords additional * The only ancient seals of Kilmahew probably extant, (the old papers of that family being lost,) I have lately discovered in the Merchiston charter-chest. 1. “ Duncan Naper de Kilmahew” is one of the inquest in the retour of Elizabeth Menteith of Lennox and Rusky, spouse of John Napier of Merchiston, dated 4th November 1473. Kilmahew’s seal is entire,—it carries a bend charged with three crescents. 2.“ James Naper of Kilmahew” is one of the inquest in the retour of the brieve of division of the Earldom of Lennox, as to Elizabeth Menteith’s share, dated in 1490. This seal has the same bearings. There are also among the Merchiston papers seals of the Lairds of Wrightshouses. 1. “ Alex- ander Naper de Wrichtyshouse” is one of the inquest in the retour of Archibald Napier, as heir _ to Elizabeth Menteith, dated 12th December 1488.

NAPIER OF MERCHISTON. 11 proof of the distinction betwixt the two families ; the arms of the husband, a crescent on a bend between two spur-rowels, being impaled with those of his wife, a saltier engrailed, cantoned with four roses. The date on the stone is 1513. While it is impossible, therefore, to follow the peerage-writers who deduce Merchiston from the progenitors of Kilmahew, the armorial bearings of the former, afford at the same time an interesting and remarkable confirmation of so much of the family legend, and prove the antiquity, if not the truth of that pretension. This proof has hitherto been lost in the inaccurate theory and false as- sumptions of our great oracles of heraldry, Sir George M‘Kenzie and Mr Nisbet, from whom it must be redeemed in order to establish its value. A transcript of a very ancient charter without a date, describes the Lennox shield as bearing a lion passant.* Such probably was the ensign of those earls until altered in some crusade, of which the cross is an obvious token. M‘Farlane of M‘Farlane, a most accurate and well-known antiquary of the last century who claimed a lineal male descent from the Earls of Levenax, gives the following traditionary account of their banner :—“ Alan M‘Arkill, second Earl of Levenax, having accompanied David Earl of Huntingdon, King William the Lion’s brother, to the Holy Land, assumed upon his under- taking that expedition, as a badge, a red St Andrew’s cross in a white field, which, with the addition of four red roses, became the armorial bearings of his successors.” + Modern writers, almost invariably state these bearings inaccurately. “ Sir James Balfour” (says Nisbet) “ in his manuscript of the nobility of Scotland, tells us, that Malcolm de Lennox went to the Holy Land, and was crossed, for which he and his posterity carried for arms, argent, a saltier engrailed gules, cantoned with four roses of the last.” { Sir David Lindesay, however, gives the cognizance of “ the Erles of La- nox of auld” in its pristine purity, argent, a saltier cantoned with four roses gules ; while for the arms of Merchiston he gives the same, with the ca- * Register House. + MSS.

The most ancient example probably extant of the Lennox saltier engraied is the seal of Alexander Napier attached to the deed of 1453. This date was about the close of the granter’s life; and as his son and heir appears to have attained the years of puberty before 1432, we may hold this example of the Lennox bearings, with a mark of difference, to be traced as far back in the fa- mily of Merchiston as the end of the fourteenth century. Assuming a cadency from the earldom, this seal would be scientifically legible. “ In carrying arms,” says Nisbet, “it has always been punctually observed by all nations, that none shall presume to take to himself the armo- rial ensign of another, and so intrude into their family and name; for arms are silent names, distinguishing families ; and even those of the same blood and parentage could not bear the coat armour of the principal family, without some variety and alteration by which they were distinguished from the stem, and from one another.” + To engrail the cross, though not a definite expression of the particular de- gree of cadency, as the minute differences of the crescent, the mollet, or the martlet, was yet sufficient to satisfy the code of arms, and such as might be adopted by a cadet, more attentive perhaps to found a new family, than to denote his precise position upon the ancient stem. | * Of this term, G'uillim, in his Display of Heraldry, gives the following quaint explanation :— « Engrailed isa term derived from the French, graisle or gresle, which signifies any thing struck with hail, which the edges of this band seem to resemble, like the edges of the tender leaf, which is often a sufferer thereby.” « Engrailed is said of crooked lines which have their points outward, as those which form the saltier engrailed in the arms of Lennox.” Nisbet's Essay on the Ancient and Modern use of Armories.—Yet in the same work he expressly states, that engrailing was a mode of differencing for cadets. ‘ When lines of partition are carried right by principal families, their cadets make them crooked by putting them under accidental forms, such as engrailed, waved, &c. for a dis- tinction.” —P. 115. + An Essay on Additional Figures and Marks of Cadency, &c. By Alexander Nisbet, gent. Edin. 1702, p. 18. 4 NAPIER OF MERCHISTON. 13 In like manner, “ the M‘Farlane,” who claimed to represent Gilchrist, a younger son of Alwyne second Earl of Levenax, carried argent a saltier waved and cantoned with four roses gules ; and it is worthy of remark, that Gilchrist was the name of a brother of him from whom, according to the fa- mily legend, the Napiers of Merchiston sprung. If these were brothers, by this variety of differencing their descendants might express their respective cadencies. Nisbet, in his Essay quoted above, has taken these very cadets as examples in support of his proposition, that, “ as arms were long in use before surnames, and instead of them served to distinguish descendants, and to show from whom they had their original, so at this day they afford us great advan- tage, by letting us know from what ancient families a great many of the pre- sent families in Europe are descended.”-—“ The Napiers and M‘Farlanes,” says he, “ cadets of the old family of Lennox; for they both carry a saltier cantoned with roses, but of different tinctures, to distinguish them from one another.” In one respect, however, Nisbet was mistaken in this reference, as he after- wards discovered, for the same mistake does not occur in his large work. Napier and M‘Farlane have always been understood to carry argent and gules, the tinctures of Lennox; but for difference, the one engrailed the cross, and the other waved it. * Thus it appears that the Napiers of Merchiston, for the very long period during which the proofs are extant, have uniformly carried the Lennox coat, with the cross engrailed for a difference, while no other family of Napier upon record approximate to those bearings. It is impossible to conjecture how this could be, if Merchiston were descended either from Kilmahew or Wrights- houses; or had acquired their pretensions to the Lennox coat through the first-mentioned ancient barons of the Lennox country, who were vassals of ‘that earldom, and yet bore coat armour totally different. It sometimes hap- pened, no doubt, that families, whose ancestors had been feudally dependant upon some great fief, carried on their own shield the armorial bearings of the over-lord, more or less differenced, according to the caprice of those who * « The M‘Farlanes carry the arms of Lennox with this difference, the saltier waved instead of engrailed,—(ought to be, instead of plain.)—A System of Heraldry, speculative and practical, with the true art of Blazon.

Edin. 14 THE LIFE OF adépted them. “ Arms of patronage,” says Nisbet in his essay on the use of Armories, “ are those of patrons and superiors, carried in part or in whole by their clients and vassals to show their dependance.” But when Alexander Napier sealed with those arms early in the fifteenth century, he had no pro- perty in the Lennox. His wealth was mercantile, and his property burgage, or at least in the vicinity of Edinburgh ; and clearly his family had no terri- torial dependance on the Lennox whatever. The anomaly, therefore, would be most remarkable, were we to suppose that Merchiston, an alleged branch of Kilmahew, pertinaciously adhered for centuries to the coat of Lennox slightly differenced, as arms of patronage and dependance, after having shaken off all ties to the earldom ; while the Napiers of Kilmahew, who remained for so many generations vassals of the Lennox, and always resided on their possessions in that country, never carried a vestige of those arms; an anomaly which would be very much increased by the consideration, that, when Napier of Merchiston married the heiress of the Lennox, he still retained the identical bearings which appear upon the seals of his grandfather and his father :—that is to say, ea hy- pothese, he preferred the arms of patronage of Lennox, though his family had no dependance upon the earldom or possessions in the district, to the pro- per arms of Lennox, which he might have adopted from his lady, who brought him in right of her own representation, the imposing dowry of one-fourth of those noble domains. That he had done so is the theory of M‘Kenzie and Nisbet. Sir George as- sumes that this John Napier, rejecting his own whatever they might have been, took the Lennox bearings from his lady, and transmitted the same to his descendants. “ Sometimes,” says that accomplished lawyer with the utmost gravity, “ the husband did of old assume on(y the wife’s arms, who was an heretrix; as Scott of Buccleugh the arms of Murdiston, and Napier the arms of Lennox, and did not bear their own native arms.”* It happens that both examples fail. “ The bold Buccleugh” did not assume “ only his wife’s arms.” The stars and crescent were his own, which originally were carried by Buc- cleugh without a bend; but with these he afterwards charged the bend of Murdiston as arms of alliance, indicating the marriage with the heiress of that house. Thus Scotland’s poet and historian, (a scion who illustrates be- * Sir G. M‘Kenzie’s Heraldry, p. 72 and 82. ie aa a tae Ow hee Ue | yy er (aire . a } en : NAPIER OF MERCHISTON. 15 yond nobility the race of Harden and Buccleugh, as Scotland’s philosopher and theologian does the race of Lennox and Merchiston,) tells us :— “ An aged knight, to danger steel’d, With many a moss-trooper, came on ; And azure in a golden field, The stars and crescent graced his shield Without the bend of Murdieston.” * But Sir George has erred even more egregiously in his second example. Napier, so far from assuming his wife’s armorial bearings to the exclusion of his own, did exactly the reverse. He retained unaltered the shield of his fathers, without allowing his lady to share it by any mode of armorial matrimony ; and it was so retained in its pristine purity for generations there- after, until it came to be quartered with the royal augmentation of Scot of Thirlstane. Nisbet has allowed himself to be misled by M‘Kenzie. In his essay on the ancient and modern use of armories, he founds a statement upon the faulty passage ; and this accounts for the following extraordinary mistake in his great work, the really valuable and delightful institute of Scottish heraldry. “ What Napier of Merchiston, the most eminent family of the name, carried of old I know not; but s¢nce John Napier of Merchiston married Margaret [Elizabeth] Monteith, daughter and co-heir of Murdoch Monteith of Ruskie, and one of the heirs of line to Duncan Earl of Lennox, in the reign of James the Second, they have been in use to carry only the arms of Lennoz, viz. argent, a saltier engrailed, cantoned with four roses gules.” + It is difficult to understand how Nisbet, an able and enthusiastic herald, came to adopt a theory of arms so unscientific. The proposition is startling, that the eldest son of that Sir Alexander Napier, whose career, we shall find, was most distinguished, had so utterly discarded the shield of a dignified pa- rentage, as to leave no trace of what Napier of Merchiston carried of old.

This lady was eldest co- heiress of the Lennox through Margaret, her paternal grandmother, daughter of the last Earl Duncan. But Elizabeth’s own father, of whom she was also eldest co-heiress, was Sir Murdoch Menteith of Rusky, a wealthy and proud baron; being heir-male of Walter Stewart, Earl of Menteith, third son of Walter, high steward of Scotland in the reign of Alexander II., and inherit- ing a considerable portion of the domains of those earls. Now the house of Rusky, of which Elizabeth is frequently styled domina in the family charters, was, as Nisbet himself informs us, “in use to carry quarterly first and fourth, or a bend cheque, sable and argent for Monteith, second and third, azure three buckles or ;” bearings of which there is not a vestige in those Lennox arms, said to have been adopted from that marriage. But further, had Napier really assumed those arms, the cross or saltier would not have been engrailed ; for undoubtedly the co-heiresses of the earldom would carry the shield of the comitatus undifferenced, though combined with their paternal coat.* It is of some importance in the history of our philosopher’s family, that this heraldic evidence should be correctly recorded, the more particularly, as it has been thrown into confusion by such high authorities. Those con- versant with the science will know that, in a genealogical point of view, a coat of arms so unequivocally proved as that of Merchiston, by the original charter * This may be seen in the arms of Haldane of Gleneagles, who married Agnes Menteith, the younger sister of John Napier’s lady, and co-heiress with her of Lennox and Rusky. Co-heiresses do not difference their arms, but carry the coat of the house they represent equally. Sir David Lindesay gives both the coat of Haldane of Gleneagles after that marriage, and of Napier of Merchiston. The latter, as already noted, he blazons without any quarterings, being the Len- nox shield, with the difference of engrailing. But Gleneagles, according to Sir David, quar- tered his wife's arms with his own, and there the Lennox cross is, as it ought to be, plain. Iam aware that, in the official register of arms in the Register-House, the cross in the Gleneagles’ coat is engrailed ; but this is a modern error.—See Sir David Lindesay’s original MS. book of He- raldry in the Advocates’ Library. 1542. ; NAPIER OF MERCHISTON. iif seal of an ancestor born before the year 1400, is not to be disregarded. The language of heraldry, though limited, is distinct ; and about the period refer- red to was cultivated as a science in Scotland, and its rules strictly observed. But, learned reader, if, like Louis XI., thou shouldst be, “ in special a pro- fessed contemner of heralds and heraldry,—red, blue, and green, with all their trumpery,—I would pray of you to describe what coat you will, after the ce- lestial fashion, that is, by the planets,” * while I proceed to record the worthies who form the paternal chain betwixt this scion of the Levenax, and the great John Napier. Sir Alexander Napier, eldest son of Alexander the first Napier of Merchis- ton, succeeded his father in the year 1454. For several years before that event he had become highly distinguished, was about court when a very young man, and probably belonged to the household of the first James, at the time of the murder of that monarch. Undoubtedly he held some post in the royal house not long afterwards, and thus found an opportunity of dis- playing his loyalty and courage in defence of the persecuted queen dowager. Urged probably by the forlorn and harassed state of her widowhood, and anxious to obtain a natural protector for the young king, Queen Joanna mar- ried the black knight of Lorn, an ally of the house of Douglas. As this marriage indicated a revival of that powerful interest in her favour, a faction of the Livingstons, by which Scotland was then distracted, became bent upon the complete subjection of the royal party. Sir Alexander Livingston was at the time governor of Stirling Castle, in which the queen had fixed her residence with her consort and her son. Upon the second day of August 1439, this fac- tion, with inconceivable audacity, seized the queen’s husband and his brother William Stewart, and, without a shadow of accusation, cast them into the dun- geons of the castle. According to the mysterious phrase of a contemporary chronicle, they “ put tham in pittis and bollit thaim.”{ Nor did they rest satisfied with this outrage. Admirably fitted for a species of barbarous ex- ercise, which has been termed “ riding rough-shod through a palace,” Sir Alex- ander Livingston and his sons, with other accomplices, determined to place the queen herself under restraint; and upon the 3d August 1439 effected their purpose, with an extremity of violence that drew the blood of at least * Sir Walter Scott. + MS.

Cc 18 THE LIFE OF one brave and loyal subject in her defence. This unmanly attack upon the queen has been doubtingly recorded by several historians ; but the fact is placed beyond dispute by one of the proudest archives of the family of Merchiston. Young Napier possessed the gallant spirit and devoted loyalty which has distinguished many of his descendants. He did his best to rescue his royal mistress, and was severely wounded in the attempt. This must have been a daring act, and rare instance of fidelity. Not only was the power of the Livingston faction then irresistible, but true chivalry seemed banished from the land. To borrow the graphic expressions of Pitscottie, these were times “‘ when the whole youth of Scotland began to rage in mischief and lust, for slaughter, theft and murder were then patent; and so continually day by day, that he was esteemed the greatest man of renown and fame, that was the greatest brigand, thief and murderer.” This ill-fated princess whom Alexander Napier in vain endeavoured to rescue, was the Lady Jane Beaufort, a daughter of the Earl of Somerset, of royal de- scent, and moreover the heroine of “ the king’s quair,” a poem that redeems an age of darkness. She had captivated, by a gentler bondage, its accom- plished author, the young King of Scots, when he was pining as a state prisoner in Windsor Tower, and cherishing the most melancholy mood of an ardent and romantic mind. Then it was that, from the lattice of his prison, overlook- ing a beautiful garden and terrace, “ on a fresh Maye’s morrow,” as the royal poet himself expresses it, “ foretired of my thought and woe begone,” he saw the Lady Jane, “‘ Walking under the tower, The fairest and the freshest young flower That ever I saw methought before that hour.” Well might the voice of that “ tassel-gentle” James I. of Scotland have per- suaded a heart more obdurate than the Lady Jane’s, that the land of the cap- tive prince was a fairy realm of song and chivalry, where never cruelty could hap- pen towoman. Yet this was the queen, whose most secluded apartments were not secure from the midnight assassin, or from the attack of ruthless traitors ! It is remarkable that Napier, having failed in the rescue, should have es- caped the utmost vengeance of the Livingstons. That he did escape with life, though not without grievous injury, and lived to see the day of retri- bution arrive long after the unhappy daughter of Somerset had found repose in the grave,—is proudly recorded in a royal charter honourable alike to the sovereign and the subject. In the year 1449 when James II. attained ma- NAPIER OF MERCHISTON. 19 jority, and four years after the death of his mother, the young monarch reared a hecatomb to her memory. The blow which then fell upon the Livingstons is depicted in the Auchinleck manuscript with so quaint an air of authenticity, that we may again quote the words of this unpublished record. “ Monunday, the 23d day of September, James of Levingstoun was arrestit be the king, and Robyn Kalendar, capitane of Dunbertane, and Johne of Levingstoun, capitane of the castell of Doune, and David Levingstoun of the Greneyardis, with syndry uthiris. And sone efter this, Schir Alexander Levingstoun was arrestit, and Robyn of Levingstoun of Lithqw, that tyme comptrollar ; and James and his brother Alexander, and Robyn of Lithqw war put in the Blacknes, and thair gudis tane within forty days in all places. and put under arrest, and all thair gudis that pertenet to that party. And all officeris that war put in be thaim war clerlie put out of all officis, and all put doun that thai put up. And this was a gret ferlie.” The king, now about to complete his nineteenth year, had been married a few months before the meeting of this Parliament * to Mary of Gueldres. It is more than probable that his young consort had heard from James the event- ful history of his boyhood, and that the expressions of her foreboding sym- pathy powerfully accelerated the fall of those who had persecuted the late queen. Certain it is, that hardly were the tournaments concluded with which James II. honoured his bride, than the scaffold streamed with blood, from which she might gather a better promise of future security, than from the stalwart blows interchanged at their nuptials, between the knights of Scot- land and Burgundy. Robert Livingston, comptroller of the royal household, and Alexander Livingston, sons of Sir Alexander, the ringleaders in the at- tack upon Queen Joanna, were hanged on the Castlehill of Edinburgh in Ja- nuary 1449; while others, more or less guilty, were at the same time cast into prison, or compelled to betake themselves to their baronial strongholds. But the justice of the young king did not stop here. Immediately after the execution of the two leading traitors, he bestowed the high office of the one, and the possessions of the other, upon Alexander Napier.t Ten years * It met in September 1449, and commenced with enactments ominous of the approaching fate of the Livingstons and their accomplices. “ Gif it happynes ony man till assist in rede, con- sort, or consal, or mayntenance to thaim that ar justifeit be the king in the present Parliament, or sall happin to be justifeit in tyme cummyn for crimes commitit agaynes the king or agaynes his derrest modir of gud mynde sall be punyst in sik lik maner as the principall trispassours.”— Acts of Parl. of Scotland. + « Et per solucionem factum Roberto de Livingstone Compotorum Rotulatori, ac usus et ex- 20 THE LIFE OF had elapsed since the perpetration of the crime ; and it is less remarkable that the vengeance of a son slumbered no longer, than that the gratitude even of a youthful king should survive so long. The fact affords an interesting illustra- tion of the disposition of the monarch, no less than of the merit of the deed re- warded. The lands of Philde, part of the lordship of Methven in Perthshire, had belonged to Alexander Livingston; but his forfeiture placed them in the hands of the king. Having already bestowed upon Napier the comptrollership, va- cant by the execution of Robert Livingston, James granted him a charter of those lands under his great seal and sign manual. This interesting charter at once records the extreme violence done to the queen-mother, and the noble defeuce attempted by her faithful domestic ; the filial indignation that pursued the traitors, and the kingly munificence that rewarded loyalty. After the lapse of nearly four hundred years it still remains among the archives of his race, from whom the lands of Philde have long since passed away. The great seal of Scotland, attached to the deed, is nearly entire ; and the king’s auto- graph yet distinct as on the day it was traced. * The daring temperament evinced by this act of his youth, seems never to have betrayed Alexander Napier into dangerous paths of ambition ; and there is ample evidence that his career, so auspiciously commenced, was ever after- wards distinguished by uncommon talents, prudence and integrity. He had witnessed the fate, and risen upon the ruin of the turbulent Livingstons. Twenty years afterwards he beheld, under a new minority, the similar treason and fate of the house of Boyd. Yet he found himself in possession of the favour and affection of the third sovereign he had obeyed, and still enjoying the re- spect and confidence of a country vexed and degraded by its brawling barons. In 1451, before the death of his father, he was one of the ambassadors upon whom devolved the difficult and important task of establishing an amicable pensas domicilii Regis.”—G'reat Chamberlain Rolls, ad an. 1448. In the same Roll :—* Scac- carium serenissimi principis,” &c. “ David Murray de Tullibardine, Alexander Ramsay de Dal- wolsy, militibus, Alewandro Naper, Compotorum Rotulatori,” &c. Napier is also designed our comptroller in the Philde charter, dated 7th March 1449. It is obvious, therefore, that he was rewarded with the office of the one traitor, and the lands of the other. * This was “ James with the fiery face.” The Philde charter, one of historical value in a reign whose records haye been almost entirely lost, will be found in the Appendix, (No. I.) with a fac-simile of the young king’s signature before his hand was stained with the blood of Earl Douglas. Another at a maturer period will be found in the note to page 25. NAPIER OF MERCHISTON. 21 relation with England. The internal dissensions of the neighbouring king- doms recommended a peaceful policy betwixt them ; but it is well known, that the stormy ascendancy of the house of York, and the ungovernable blood of Douglas, rendered that mission one of extreme delicacy and doubtful result. The negotiations however terminated favourably ; and a truce was concluded for three years.* A few years afterwards, and subsequent to his father’s death, we find him occupying the civic chair of his native city ; an honour for many years bestowed upon successive representatives of his family. This office he seems to have held as frequently as his numerous state employments permitted him to exercise its functions. There is evidence still extant of his having been provost of Edinburgh in the years 1455, 1457, and 1469. Wherever the best interests of his country were to be protected his name will be found. It had been discovered that merchants speculated upon the bullion, which, as the coin exceeded the statutory value, they were tempted to export. A statesman, and probably a merchant, Napier seems to have avoided the vices of both. In 1457, he is one of those “ ordaynet and chosen for visit- ing the moneyes.” For many years afterwards this important subject occu- pied the deliberations of Parliament, and his services are frequently in requi- sition. By a commission under the privy seal, preserved among the family papers, and dated at Edinburgh the 24th February 1464, “ Sir Alexander Napar of Merchamston,” and others, are appointed searchers of the port and haven of Leith, in order to prevent the exportation of gold and silver ; and in 1473, his name again occurs as a parliamentary commissioner for “ searching of the money.” The unfortunate death of James II. did not retard the successful career of Sir Alexander Napier. At the commencement of the new minority, the attend- ant circumstances of which were almost a repetition of those in the previ- ous reign, he again held the office of comptroller of the royal household. + If * The indenture is dated 14th August 1451, and signed, T.

All these individuals set out, in the Sep- tember following, on a pilgrimage to Canterbury, as appears from a safe-conduct granted to them for that purpose by the English government.—Federa. + This appears from a discharge among the Merchiston papers, under the privy-seal of James III., bearing, that the king had received “a dilecto milite nostro Alexandro Napare de Mercham- 22 THE LIFE OF his talents were not ill appreciated, neither were they spared. His king and country could scarcely have extracted more good service from the intelligence and activity of a single subject. Hurried repeatedly and alternately from the royal household to the civic chair,—from judicial functions to legislative deli- berations,—from domestic finance to foreign diplomacy,—his whole life seems to have been a constant round of dignities, embracing occupations of the most opposite and arduous nature. With the Abbot of Melrose and others, he ob- tained letters of safe-conduct again to pass into England in 1459, as one of the Scottish commissioners appointed to treat in that year. In 1461 he was in still higher consideration. He had obtained the then illustrious honour of knighthood, was appointed vice-admiral of Scotland, and with these accumu- lated dignities, proceeded as one of the ambassadors to England. * At this critical period, the rose of Lancaster had been torn and trampled on the bloody field of Towton ; and old Holyrood, the sanctuary of royalty in distress, afforded an asylum to the exiled Henry, and his spirited consort Margaret of Anjou. The queen-mother of Scotland bestowed upon them all that the strength of her councils, and the weakness of her kingdom could afford. But the expatriated monarch did more than rely upon Scottish gene- rosity. To aid him in regaining his crown, he tendered to Scotland the castles of the frontier, he promised an English dukedom to the powerful Earl of Angus; and upon the city of Edinburgh he bestowed the prospect at least of very valuable commercial privileges. Amid this lavish policy or gratitude, the family of Merchiston was not overlooked. Henry bestowed a pension of stoune nostrorum compotorum rotulatore bonum fidele et finale compotum,” &c. dated at Stirling, 7th July 1461, “ et regni nostri primo.” wc It is interesting to observe the young king’s signature to this deed, of which the above is a fac- simile. He was anointed and crowned at Kelso on the 24th of August 1460, when a number of knights were made, and probably among the rest Sir Alexander Napier. James was just eight years, two months, and twenty-three days old at his coronation. His signature at a maturer age will be found in the Appendix. * Foedera, Tome xi. 476.

He accordingly sent letters, of no very amicable as- pect, to James III., complaining of the indignity. Repeated remonstrances were at length accompanied with an argument more formidable to Scotland than a declaration of war. Denmark demanded the arrears of the Hebudian annual, due to the crown of Norway from those islands ; and Scotland found the claim not easy to evade either in law or honour. The menace was met, however, by a courtship of Denmark’s daughter on behalf of the young king of Scots ; and the latter, instead of paying tribute, eventually received the va- luable cession of the islands themselves, in satisfaction of the arrears of the princess’s dower. Lord Napier, in his genealogical account of the family, states that, “in a manuscript book of heraldry, formerly belonging to that great antiquary the laird of M‘Farlane, and now in the library of Andrew Plumber of Sunderland- Hall, Sir Alexander Napier is said to have been sent with Andrew Stewart, the lord-chancellor, to negociate the marriage betwixt King James III. and the king of Denmark’s daughter.” Though I have not discovered any official record of this fact, it can hardly be doubted. Napier, during a period of twenty years, was continually employed in the most difficult and important missions of his day ; and the circumstances of the Danish alliance were such as scarcely to dispense with his experience in foreign negociation. Besides, his eldest son was by this time married to a grand-niece and co-heiress of * See Appendix, (No. II.) + Betwixt the years 1464 and 1468, Sir Alexander’s services were bestowed at home. In 1467 he is one of the commissioners for a tax raised upon the barons, &c. “ Item, anent ye taxt of the barouns, it is ordanit yat yar be ane inquisitioun taken be ye personnes efter folowand and depute yarto and nemmyt in ilk schir, and to retour again ye avale of ilk mannis rent, and efter ye cummyn of ye retouris, that’ye abbot of Halirudhous, Sir Alexander Napar, and Thomas Oliphant sall modyfie and set ye said taxt evinly apoun all ye persounis yat ar ordanit to contribut yarto.”—“ Item, it is ordanit yat ye abbot of Halirudhous be resavoir of ye taxt of the clergy, Sir Alexander Napar of ye barons, and Thomas Oliphant of ye baronis.’—Parl.

James Stewart, that son of the Duke of Albany who alone escap- ed by flight from the scaffold where the Duke and his other sons perished, left no legitimate offspring ; but the powerful talents of Andrew Stewart, his natural son, raised the latter to that elevation which, under the title of Lord Avandale or Evandale, he so long held in the kingdom. No one had more opportunies of knowing, or could better appreciate the talents of Napier, than the chancellor; and that he was accompanied in this negotiation by his near connection, a man who for so many years had divided his energies betwixt foreign policy and domestic finance, may be assumed upon the authority quot- ed.* “ The negotiations” (says Mr Tytler, in his History of Scotland now in progress of publication) “ upon this occasion appear to have been conduct- ed with singular prudence and discretion ;” and he adds this lively sketch of the happy result :—“‘ Having brought these matters to a conclusion, in a man- ner honourable to themselves, and highly beneficial to the country, the Scot- tish ambassadors, bearing with them their youthful bride—a princess of great beauty and accomplishments—and attended by a brilliant train of Danish nobles, set sail for Scotland, and landed at Leith in the month of July, amidst the rejoicings of an immense assembly of her future subjects. She was now in her sixteenth year ; and the youthful monarch, who had not yet complet- ed his eighteenth, received her with that gallantry and ardour which was incident to his age. Soon after her arrival, the marriage ceremony was com- pleted, with much pomp and solemnity, in the Abbey Church of Holyrood ; and was succeeded by a variety and splendour in the pageants and entertain- ments, and a perseverance in the feasting and revelry, which were long after- wards remembered with applause.” + Sir Alexander Napier must have been very wealthy. I have not been able to trace the history of the lands of Philde, or to ascertain their extent; but the comptroller, before the death of his father, took his designation from those lands, which probably were of considerable value. A crown charter, dated * In the Parliament held 6th May and 2d August 1471, Sir Alexander is designed Secretary —‘ Parliamentum inchoat. apud Edinr. 6th May,” &c. “ per prelatos, barones, ac commissarios subscriptos ;” among others, the Chancellor Avandale, and “ Dominum Alexandrum Naper, Secre- tarium.’—Rotuli Scotia. + History of Scotland, iv. 221, 222 NAPIER OF MERCHISTON. 25 24th of May 1452, to “ Alexander Napare of Philde,” of the lands of Lin- doris and Kinloch in the shire of Fife, is yet among the family papers. He succeeded his father in the estate of Nether Merchiston, and the feu-charter of his own acquisition of Over Merchiston from the church of St Giles, is preserved among the archives of Edinburgh. He held of the crown cer- tain lands called the Pulterlands, to which was attached the hereditary office “ Pultrie Regis,” or king’s poulterer, the reddendo of which was an annual pre- sent of poultry to the king s¢ petatur tantum. These lands are described as lying near the village of Dean, in the shire of Linlithgow. Sir Alexander also acquired the lands of Balbartane in Fife, formerly belonging to James Lord Dal- keith.* Besides these extensive estates, it appears from the great chamberlain rolls that he obtained grants of casualties due to the crown ; and from the offices he held, his public emoluments could not have been inconsiderable. It is also very probable that he indulged in merchantile speculations. The character and status of a Scottish merchant then ranked high, and was not incompatible with that of a diplomatist and a statesman. Mr Tytler mentions as a re- markable circumstance, that in the reign of James III., “ the nobility and even the monarch continued to occupy themselves in private commercial specula- tions, and were in the habit of freighting vessels, which not only engaged in trade, but falling in with other ships similarly employed, did not scruple to attack and make prize of them.” There are no indications of such predatory habits on the part of our philosopher’s ancestors; but from the circumstance, that the three first Napiers of Merchiston in lineal male descent were succes- sively provosts of Edinburgh, it may be assumed that these wealthy and dis- tinguished burgesses were “ Merchants and rich burghers of the deep.” + * This appears from a discharge under the sign-manual and privy-seal of James II. to his “lovit and familiar squyre, Alexander Napare of Merchamstoune, of al soumes of mone, &c. ressavit. be the saide Alexander Napare of Merchamstoune, the time he was in office til us of comptrollership, or ony uther time to ye date of thir presant letters, and specially of the soume of five hundredth marks, aucht till us be ye saide Alexander for ye charter of the lands of Balbartanis with ye miln liande within the sheriffdome of Fiff, some time belonging to our cousin James, Lord Dalketh,” &c. dated at Edinburgh, 24th October, in the 20th year of the reign (1456.) + “ In the Parliament of Scotland, 1466, enactments were passed, « That na man of craft use merchandise.

He was in the town of Bruges, “ taking up finance,” and making purchases for James III. some time prior to January 1472. This appears from the following receipt, under the hand and seal of the treasurer of Scotland. “ T graunt me to have resavit in oure Soverane Lords name be the handis of ane Richt Honorable and Worshipfull man Sir Alexander Napare of Mer- chamstoune Knicht the soume of twa hundreth pundis of usuale monee of Scot- land of certane finance tane up be the said Sir Alexander in the toune of Bruges, in Flanders, and als that the king has remittit and forgevin him ane hundreth crounes for certane grath* coft and brocht hame to the king be him, of the quhilk soume of [L. 200] I hald me wele content and payt, and thereof in oure saide soverane lords name, quitclames and discharges the saide Sir Alexander of the saide soume of monee and al uther quhame it efferis be this my presente ac- quitance. ‘To the quhilk I have set my signett, and subscrivit with my awin hand at Edinburgh, the xxvii. day of Januare, the year of God” (1472.)— “ Thesaurar J.

The harness and weapons for a man-at-arms in Scotland were frequently selected from the conti- nent, and the records of Parliament in the reign of James II. contain a characteristic statute “ Anentis harness to be brought hame be the mer- chands.

NAPIER OF MERCHISTON. 27 The year 1449, that in which James II. avenged the wrongs of his mother, had commenced auspiciously with his marriage to the princess of Gueldres. Some of the negotiations which about twenty years afterwards were intend- ed to renew and strengthen the consequences of this prudential alliance, were committed to the indefatigable sagacity of Sir Alexander Napier. ‘The wounds received in defence of a persecuted queen well became the venerable knight of Philde in his latest embassy to the Court of the Golden Fleece, which oc- curred in the year 1473. Sir Alexander was no stranger to Charles the Bold. The tenor of his in- structions from James III., as well as his private papers, prove that he had visited Bruges and the court of Burgundy repeatedly before this occasion ; * and the last public duty in which he appears to have been engaged was to negotiate, under difficult circumstances, with this gorgeous and overbearing duke. The written instructions which he then received from his sove- reign are still preserved in the Merchiston charter-chest, though unknown to history. While the political relations of England and France, as affected by the am- bition of Burgundy, are recorded in the contemporary chronicle of Commines,— ' picturesque as Burgundian chivalry ; and in the modern history of Barante,— exuberant and glowing as romance ; our own historical sources afford only im- perfect glimpses of the foreign policy of Scotland in those stirring times. Mr Tytler, the latest historian of the period, has done much to elucidate the ob- scurity ; but he confesses the paucity of proofs; and, in some of his deductions, has perhaps misapprehended the real tone of our foreign relations in the last quarter of the fifteenth century. He admits, however, that the instructions to the Scottish ambassadors to England and Burgundy about the year 1470, “ were unfortunately not communicated in open Parliament, but discussed se- cretly among the Lords of the privy-council, owing to which precaution it is * From a document among the Merchiston papers, it appears that Sir Alexander Napier had lent eighty pounds Scots to William Lord Graham (ancestor of the Duke of Montrose) in the town of Bruges. It appears from the Feedera, that Lord Graham obtained a safe-conduct to pass into England, and from thence to the continent, 23d December 1466. There were great festivi- ties in Bruges at the nuptials of Charles the Bold of Burgundy in 1468, when the towrnament of the golden tree was held; and Sir Alexander Napier was probably selecting armour for his sove- reign in that romantic town, when it was under all the excitement of the dazzling presence of a chapter of the Toison d’Or. 28 THE LIFE OF impossible to discover the nature of the political relations which then subsist- ed between Scotland and the continent.” * The desideratum is, to a certain extent, supplied by these written instructions to Sir Alexander Napier. They furnish new facts filling up chasms in some interesting matters, cor- roborate our historian in some views of the policy of that obscure reign, and correct him in others. The language and details of this venerable state paper. which is not even to be found in the late splendid edition of the Acts of the Scot- tish Parliament, are so interesting as to deserve to be literally transcribed. It will be found, therefore, in the appendix. But the obscurity of the ancient style requires elucidation; and a general view of the historical incidents upon which the instructions cast some additional light, may not be out of place. The spirit, at least, of Charles “le temeraire,” did not disgrace the illus- trious memory of his father, or the high blood of England and France that mingled in his veins. Well and quaintly is he described by a writer of his own times, as “ Duc de Bourgogne, prince de la maison de France, surnome terrible guerrier, et qui n’a jamais cedé aux grands Roys.” | This terrible war- rior, whose heart bounded lightly to the bugle of chivalry, till it learnt a strange lesson of terror from the horns of Uri and Unterwalden, and was crushed by “ The might that slumbers in a peasant’s arm,” — then played a desperate game against the crafty Louis XI. which involved the whole of Europe. Connected with England by lineal descent from old John of Gaunt, and closely allied to Scotland through the House of Gueldres, Charles received embassies from all quarters, rendered frequent and anxious by the daring position which he had assumed towards the illustrious crown of which he was but a feudatary. It was the policy of Scotland to reconcile France and Burgundy, her ancient allies. The King of England, than whom, to use the words of James’ diplomatic instructions to Sir Alexander Napier, “ nane uthir prince made wer upon Scotland,” courted Burgundy more earnestly than be- came his dignity, and even bestowed the hand of his sister Margaret upon the terrible guerrier. It was Edward’s object, though scarcely secure at home, to farther his own ambition by fomenting the quarrel, and supporting the war betwixt Charles and Louis. The Duke, on the other hand, in order to relieve England as well as to realize his own unbounded views, laboured to prolong * Vol. iv. p. 236. t+ Appendix, (No. III.) t “ Discours tire d’un viel Manuscript.” NAPIER OF MERCHISTON. 29 those doubtful pauses of hostility betwixt that country and Scotland, which (again to quote the words of Napier’s instructions) were dignified with the names of “ pese and trewes,” though, it must be confessed, not “sa sicker bundyn.” But Charles found it no easy task to engage James III., however small the pretensions of that monarch to the nom de guerre of his cousin, in a peace even of limited duration with England. It appears that the king of Scots was far from evincing that disinclination to hostilities with the sister kingdom which Mr Tytler infers from the muniments he had examined. Our historian conceives that “the repeated consultations, between the commissioners of the two countries on the subject of those infractions of the existing truce which were confined to the borders, evinced an anxiety upon the part of both to remain on a friendly footing with each other.” Butthe instructions seem rather to contradict this view. It is there expressly stated, that James had absolutely refused to ratify a treaty with his cousin of Burgundy, to which his own ambassadors had agreed ;_ be- cause he thought the terms too favourable to England. It may be true that James and his ministers had full “ occupation at home,” but it is by no means proved that the former “ wisely shunned all subjects of altercation which might lead to war.”* On the contrary, having despatched ambassadors to Burgundy for the purpose of renewing the offensive and defensive alliance entered into betwixt their respective fathers, the king of Scots proved not very tractable on the subject of peace with England. Hehad introduced some exception in favour of his father-in-law, the king of Denmark. Charles, on his part, proposed an ex- ception in favour of the king of England, and had sent his own ambassadors to James urging him to prolong a truce with that country for the space of two years, as a personal favour and support to Burgundy. The Scottish ambassadors in Flanders consented to the exeption proposed by the Duke of Burgundy ; but James refused to ratify what he considered a reckless or negligent concession on the part of his ambassadors. He immediately furnished Sir Alexander Napier with these special and confidential instructions, deprecating in strong terms the exception in favour of the only king who made war upon him,—an important item in a treaty of mutual defence,—and he was too much in ear- nest to stand upon ceremony with regard to the king of Denmark, but at once departed from his own condition in favour of that monarch. With these origi- nal exceptions left out, James sent letters under his great seal to the Duke, com- prehending “ baith the auld confederatioun and the new” in all other points ; * Tytler, iv. 239. 30 THE LIFE OF and “ requerand his said cousing the Duc, that gif the forme of the said new confederatioun send to him be acceptable, that he will ressave it, and deliver siclike under his gret sele to the said Sir Alexander.” Further, the king of Scots complains bitterly of injuries and indignities from England, committed upon his lieges both by sea and land, and still remaining unredressed, though, says James, Edward had pledged his royal word, and bound himself in writ- ing to make immediate reparation. He declares that nothing less than his own affection and respect for his cousin of Burgundy could have induced him to listen to the Duke’s urgent request of a truce with England, and he re- quires Charles, as an indispensable condition of the stability of any such truce, to send ambassadors of the highest credit to England, to demand compensation from Edward for the Scottish grievances ; and in particular, “ to mak him redress incontinent the bargh broken at Balmburgh.” Instead of shunning all subjects of altercation with England, King James, inter alia, harped inces- santly upon this same Bishop’s barge for years until he got amends.* Ag- gressions from the states of Burgundy, of more consequence to Scotland than the pillage of the blessed ship St Salvator, are also complained of in Na- pier’s instructions. The severe treatment experienced by our merchants in the Hans towns opposed serious impediments to commerce. Animosities grow- ing out of the thievish propensities of certain Scottish merchants, led to re- prisals from the states of Flanders. After a long course of mercantile hos- tilities, the Bremeners captured a vessel and cargo of considerable value be- longing to the town of Edinburgh. This severe indignity to our commercial flag occasioned an embassy to the Low Countries, headed by the provost of Edinburgh, conveying anxious proposals for a treaty of redress and mutual concessions. An adjustment was then effected which sprung from the wise and able administration of Bishop Kennedy; but it appears from Napier’s in- structions, that a good feeling betwixt the mercantile interests of the two coun- tries was not re-established even in 1473, thirty years subsequent to the bishop’s mission. James, after his indignant and spirited expressions against the king of England, ventures in a minor key, to remind the dangerous duke, ( * his derrest cousing and confederat,”) of the ancient commercial ties betwixt * See Pitscottie for the building of the “ Bishop’s barge” by Archbishop Kennedy ; and Les/y for its wreck and spoliation. Rymer (xi. 850,) records an acquittance by Thomas Bishop of Aberdeen, dated 3d Feb. 1474-5, for 500 marks English, “ pro finali concordia, &c. super querelis unius navis vocati le Salvator que fracta jucta Bamburgh.” NAPIER OF MERCHISTON. 31 them ; and complains, soéto voce however, that his merchants are aggrieved as to their privileges in the town of Bruges, “ and nocht sa wele tretit be thame as frendis suld be, na as thai are tretit in Scotland quhen thai cum.” * Another very anxious object of Sir Alexander Napier’s mission was “ the matter of Gelrill.”. This item of the instructions regards a wild and sad story in the history of the dutchy of Gueldres ; a romance in which Charles the Bold is a prominent actor, and James III. a spectator deeply interested. + For a long period of the fifteenth century, that unhappy dutchy presented the revolting spectacle of a son leagued in deadly enmity against his father. The eldest daughter of the reigning Duke Arnold was that princess whom Philip of Burgundy conducted with great pomp into Scotland as the bride of James II., and who became the mother of James III. The consort of the Duke of Gueldres was Catherine of Cleves, an undutiful wife and mo- ther, who instilled lessons of disobedience and revolt into the mind of their son and heir, the young Adolphus, which the latter too aptly acquired. In consequence chiefly of the conduct of this princess, disorders of long endur- ance arose in the dutchy. An unnatural war, in which Arnold was opposed by his consort and son, terminated favourably for the old Duke. Adolphus fled to the court of Burgundy, where he was more kindly entertained by his uncle Philip than his own conduct had merited. He afterwards became a follower of the cross, and a knight of the high and holy order of St John of Jerusalem. But the chivalry of Christendom failed to reclaim the heart of Adolphus. He returned from the Holy Land to Burgundy, where his uncle again received him with the highest distinction,—bestowed upon this unworthy prince the hand of Catherine of Bourbon, (Philip’s niece) and invested him with the col- lar of the Toison d’or. It was the object of the benevolent Duke of Bur- gundy to reunite the unhappy house of Gueldres ; and through his exertions, the festivities of this alliance were distinguished by an apparent reconciliation of Catherine to her husband, and Adolphus to his father. It appears that the old Duke of Gueldres, notwithstanding all his wrongs, still dearly loved his * « Come youngster, you are of a country I have a regard for, having traded in Scotland in my time. An honest poor set of folks they are.”—Louis XI. to Quentin Durward. + “ Well, my young hot blood,” replied Maitre Pierre, “ if you hold the Sanglier too scrupu- lous, wherefore not follow the young Duke of Gueldres ?”—“ Follow the foul fiend as soon,” said Quentin. “Harkin your ear; he isa burthen too heavy for earth to carry. Hell gapes for him. Men say that he keeps his own father imprisoned, and that he has even struck him. Can you be- lieve it ?”—Quentin Durward. 32 THE LIFE OF son, and the occasion was to him the happiest of his life. With a heart reliev- ed from a load of sorrow and anxiety, he retired early from the ball to repose. But Adolphus and his mother had plotted a cruel conspiracy. A party of rebels who espoused their cause, made a desperate midnight attack upon the chamber of the Duke, who supposing the disturbance to be a bridal frolic, ex- claimed, with a bonhommie worthy of a better fate, “ Let me sleep, my chil- dren, I am too old to dance.” When he heard the fierce reply, “ You are a prisoner,” his unsubdued affection burst forth in the exclamation, “ Is my son safe ?” and even when, at the head of the conspirators, that son replied, * Yield! you have no alternative!” the old Duke uttered but a single re- monstrance,—* Alas! Adolphus. what make you there?” He was dragged nearly naked to the castle of Burin, where he long languished in a dungeon, only visited by the light of day through a miserable aperture, sometimes dark- ened by the shadow of the remorseless Adolphus, * who came there to load his aged parent with execrations. Not long after the death of Philip the Good, Charles his successor, forced Adolphus to release the Duke of Gueldres. Upon this page of history, Sir Alexander Napier’s instructions afford a new commentary. They account more naturally than historians have been able to do, for that apparently desperate and sudden inclination to go a-roving, which for a time possessed James III. They also prove that’ Charles of Bur- gundy actually extorted the succession of Gueldres from the oppressed and aged Duke. When released by the determined though selfish interference of Burgundy, the sole remaining anxiety of Duke Arnold was to exheridate his only son, who had embittered his declining years, and had so recklessly crushed the last spark of parental affection. But Arnold had no partiality for Charles the Bold; nor did he entertain an idea that the haughty Duke of Burgundy should become his successor. He looked to Scotland, where his eldest daugh- ter,—at one time his presumptive heiress,—had borne three sons, who seem- ed to do more credit to the house of Gueldres than his degenerate Adolphus. Failing that prince, his natural inheritor was James of Scotland; and the fond hope of the old man was to persuade the monarch to come in person to the dutchy, and be formally installed in the succession forfeited by the treason of the young Duke. If James could not quit his dominions, Arnold looked for the presence of one or other of his remaining grandsons,—the Duke of Albany and the Earl of Mar,—whose knightly bearings and ardent tempera- * This horrid scene attracted the pencil of Rembrandt. NAPIER OF MERCHISTON. 33 ments fitted them much better than the king for such an enterprise. It ap- pears from Napier’s instructions that these wishes had been expressed in a letter from the Duke of Gueldres to his royal grandson, which, so far as I can discover, is unknown to history. Mr Tytler imputes the unusually restless impulse of James to the warlike persuasions of Concressault, the French en- voy, who urged in the name of Louis XJ. the conquest of Brittany. But James was not easily beguiled into such extravagant manhood; and why he so readily agreed to yoke the red dragons, and take the reins himself, contrary to the earnest and almost ludicrous remonstrances of Parliament, is a problem in the effeminate character of that monarch. The letter from his grandsire of Gueldres, “ exorting and requiring” him to pass into the dutchy as his na- tural inheritance, for the purpose of being unanimously installed by the nobles and barons of that rich principality, must have had a more powerful effect upon the dispositions of James III. than the warlike voice or wily promise of “* Mesnil Penil.”* The alternative proposed by his grandfather, namely, to send Albany or Mar as a substitute, and which proposal was likely to be more eagerly received by his brothers than suited the views of King James, must have added to his inclination to go in person; and the idea that the letter in question was at least his chief instigation, is strengthened by the fact, that shortly after the sudden death of the old Duke of Gueldres, James aban- doned his enterprise altogether. Mr Tytler, however, refers the king’s final determination to another cause. “On the 17th March 1472,” (says that his- torian,) “ the birth of a prince, afterwards James IV. had been welcomed with great euthusiasm by the people; and the king, towhom, inthe present discontent- ed and troubled state of the aristocracy, the event must have been especially grate- ful, was happily induced to listen to the advice of his clergy, and to renounce for the present all intentions of a personal expedition to the continent.”+ Duke Ar- nold died upon the 24th of February, in the year 1472,! that is to say, towards * So Barante terms the Sieur Concressault, perhaps for Monipenny ? Pinkerton, (i. 294,) speaking of Albany’s reception in Paris, 1479 says, “ Louis ordered Monipenny and Con- cressault, Scotishmen of rank, to attend the Duke ;” but were Monipenny and Concressault two persons? ‘“ Monipenny de Congirsalte” was an individual well known in the reigns of James II. and III. + History, iv. p. 241. { Lart de verifier les dates.—Pinkerton is wrong in his chronolgy of Duke Arnold's death. He says “ Arnold of Egmont became Duke of Guelder in 1423, and died in 1468. His son hay- ing rebelled against him, he left his territories to Charles the Bold, Duke of Burgundy.” —History of Scotland, V. i. p. 206. E 34. THE LIFE OF the close of the year which, according to the Scottish kalendar of that period, end- ed upon the 24th day of March. There is no date attached to the instructions themselves, but they bear internal evidence of having been written immediate- ly after Arnold’s death; and another document which accompanies them among Sir Alexander’s papers, fixes their date immediately after the Ist of May 1473. The document alluded to is a letter of protection from James ITI. under his privy-seal, for the lands, servants, and goods, of his beloved familiar Sir Alexander Napare of Merchamstoun, knight, ordered forthwith beyond seas on his majesty’s service; and from all pleas, &c. from the day of his departure to the day of his return, and forty days thereafter, dated at Edinburgh the 1st day of May 1473.* The conduct of the King is thus very naturally accounted for. His grand- sire’s invitation was a powerful inducement; but on receiving intelligence of that prince’s death, James found it convenient to pause before coming into contact with his cousin of Burgundy, whose affectation of retributive jus- tice in keeping the young Duke Adolphus under personal restraint, very slightly veiled the most interested designs. The power and ambition of Charles was notorious; and James, having lost the countenance of his father- in-law, must have felt how hopeless would be a descent upon the proffered dutchy, unless beaconed by the imperious star of Burgundy. Under this new aspect of affairs, and while his prelates and lords of Parliament were still un- certain of his resolves, and devising new expostulations to prevent his quitting the kingdom, the King of Scots instructs Sir Alexander Napier to urge the Duke of Burgundy to send “ in haistywiss his entent thereapon,” to afford the king counsel and directions in the matter, “ and quhat that he sal traist and lippin thereto, sen he [ Burgundy ] has the personage in hand that pretends to have richt or interess thereto.” In vain had the Duke of Gueldres struggled to place a grandson on his throne ; the power of Charles the Bold was at its zenith, and his very con- science was clothed in steel. On the 30th December 1472, Arnold had been compelled finally to conclude at Bruges a cession of his territory in favour of * « Jacobus,” &c. “ sciatis nos dilectum famuliarem nostrum Alexandrum Napare de Mercham- stoun militem, quem ad partes transmarinas nostris in negotiis derigimus de presenti,” 3c. “ da- tum sub nostro secreto sigillo apud Edinburgh primo die mensis Maii A. D. millesimo quadringen- tesimo septuagesimo tertio, et regni nostri decimo tertio.” At the very time, John Haldane of Gleneagles was sent ambassador to Denmark, probably on the same subject. NAPIER OF MERCHISTON. 35 Burgundy, reserving to himself a liferent possession, which, however, bur- dened the grant only two months. The earnest request transmitted in writ- ing to his grandson about the period, leaves no doubt that this will (so called) was extorted. Perhaps, in that cession the aged and heart-broken sovereign signed his own death-warrant ; the times and the actors were not uncongenial for such deeds, and a surmise as dark shrouds the fate of a prince of Bourbon in a more enlightened age. The next object of the Duke of Burgundy was the disposal of that * perso- nage” whose “ richt or interess in the matter of Gelrill” might interfere with the equivocal will of the old duke. If the concluding words of James’ instruc- tions meant to convey no hint favourable to the wretched Adolphus, Charles, who in such matters required little prompting, anticipated so far at least the views of his ally. At the very moment when Napier was about to leave Scot- land, the “ terrible guerrier” was dealing with the disobedient son according to his deserts,—but neither for the sake of justice nor of King James. Adolphus was a knight-templar and a knight of the golden fleece; and Charles was determined that the imposing solemnity of his fall should dazzle the eyes of Europe, and veil the selfish motives of his judge. He cited him before a chapter of his order assembled at Valenciennes on the 3d day of May 1473 ; and Sir Alexander Napier may have once more beheld the Court of Burgundy glowing with chivalry. No picture of arms could equal a chapter of the Toi- son d’Or ; and the princes who flocked to its imperative summons must have rendered the place of its enactment an imposing scene. Upon these occa- sions Burgundy displayed his most gorgeous array. He replenished his order with the most illustrious names in Europe; and now it was a sovereign prince whom he summoned to defend his honour before the assembled chapter. But the young Duke of Gueldres, though cited, was not permitted to quit his pri- son. He was only allowed to appear by a procurator, and as might be ex- pected, the knights of the golden fleece in one voice sustained the will of the late duke, and pronounced a decree of perpetual imprisonment against his son. So ended the hopes of King James in that quarter, his truant disposition, and the last diplomacy in which Sir Alexander Napier received instructions from his sovereign. I may have erred in this application of the document to il- lustrate the history of those remote times, and have given it in the Appendix, that the reader may judge for himself. It is a very interesting fragment of 36 THE LIFE OF history, clothed in the quaint terms of our ancient language upwards of three hundred years ago; and now, When the knights are dust, Aud their good swords are rust, And their souls are with the saints, we trust, casts a light like the dubious gleam of a corslet, upon times illuminated by few or no records. Sir Alexander died soon after, and while he was master of the household to James III. On the 15th February 1473, being the close of the same year at the commencement of which the Knight of Philde’s last mission occurred, John Napier of Rusky was infeft in the lands “ vulgariter nuncupat. le pultre land,” as nearest lawful heir of the late Sir Alexander Napier, his father. I have quoted below the last grant he received under the hand and seal of his royal master, as it forms an apt conclusion to a career which must have been eminently distinguished by talent and virtue in a barbarous age.* * « James, be the grace of God, King of Scottis, to all and sundry oure liegis and subditis, quham it efferis, quhais knaulage thir oure letters sal cum, greting.—Forsamekill as oure lovett fa- muliare knicht and maister of housshald, Alexander Napar of Merchamstoun, has componit with us on the behalve of Johnne Napare his sone and are, and Elizabeth his spouss, for the soume of twa hundir markis, and fifty markis of usuale money of oure realme, for the composition of the parte of the Erldome of Levenax, pertenyng to the saide Johnne be ressoun of his saide spouss, in a part heritare of the said Erldome.

She married Sir James Edmonstone of Edmonstone. The mother of her husband’s father was the Princess Isabella, daughter of Robert II. Sir William Edmonstone, her husband’s uncle, (being the younger brother of his father,) again allied his family to the royal house. He married the Princess Mary, eldest daughter of Robert III., his own first cousin. Thus the grandchildren of Sir Alexander Napier were the great-great-grandchildren of Robert II. and one generation nearer in the collateral line to Robert III., which monarch was also the father- in-law of their paternal uncle. John Napier of Rusky, and third of Merchiston, belonged to the royal household during the zenith of his father’s active career,}.and stood high in the estimation of his countrymen. It has been already observed, that he was par- ticularly noticed by Henry VI. when that unfortunate monarch was a re- fugee in Edinburgh ; and, from the situations he held, there can be no doubt that this John Napier inherited some portion of his father’s talent, and was * See Note (A.) + In a charter of the lands of “ Calzemuk,” from the Queen dowager of James II., dated 16th July 1462, to John and his second son George, the former is designed “ dilecto familiari scutifero nostro Johanni Napare de Rusky.” Mary’s seal is attached ;—the lion of Scotland and the lions of Guelders parted per pale.

He is repeated- ly mentioned, during a period of many years, commencing before the death of Sir Alexander, as one of those chosen, “ ad causas et querelas audiendas in parliamentis,’—a committee of Parliament, which necessarily comprehended a selection of the leading and talented men of the country. His name also frequently occurs in the “ acta dominorum concilii,” as one of the Lords of Council, to whom, before the establishment of a Court of Session, the supreme jurisdiction of the country was intrusted. In these important legislative and judicial functions, he seems to have supplied his father’s place when that statesman was abroad on the public service, and also after his death. In like manner, he was at various times provost of Edinburgh. It is a notable in- stance of the high estimation in which the lairds of Merchiston were held, that three of them, in immediate lineal succession, repeatedly held that respon- sible office during a period of half a century ; and in times which, though tur- bulent and unlettered, are regarded as having been highly auspicious to the growing consideration and improvement of the city of Edinburgh. The pe- riod embraced by the dates of these successive provostships in the Merchiston family is said to have been palmy days for old Edina, who then commenced that mighty march of improvements, which has progressed from the Cowgate to the Acropolis, outstripping the admiration of the world, and the patience of her taxed inhabitants. In a Parliament held at Edinburgh on the 16th February 1483, when Napier sat as one of the lords auditors, a case occurs in which he is the party. It seems sufficiently curious and characteristic of the times to be quoted from its unpublished record. On one of the sederunts of that Parlia- ment, (20th February,) “ The Lordis Auditoris decretis and deliveris, that John Courrour sall content and pay to Johne Naper, provost of Edinburgh, a croce of gold wayand ane unce, price L. 6, with five sapphiris, price twenty shillings, a grete perle, price forty shillings, and thre uther small perle, price of the peice three shillings ; because there was a day, assignit of befor to the said John Currour, to have brought his warrand anent the said croce, and failzeit therein the said day ; and that letters be direct to distrenze him therefor.” * There is every reason to believe, that during the fickle turbulence which characterized the unhappy reign of James III. he had never swerved from his * Acta Auditorum. NAPIER OF MERCHISTON. 39 allegiance, and that he lost his life under the standard of that monarch, upon the disastrous day of the battle of Sauchieburn. A new and shameful ral- lying point had been seized by the factious towards the close of the year 1487. The young prince of Scotland, James Duke of Rothsay, had not com- pleted his fifteenth year; and the standard of rebellion and patricide was un- furled over the head of a boy. The unnatural struggle, which commenced on the 2d February 1487, was short though violent, and the result is well known. Upon the 11th June 1488, the insurgents defeated the king’s forces at Sauchie, near the memorable field of Bannockburn ; and James himself was basely murdered on his flight from the lost battle. In a charter of that mo- narch, dated less than a twelvemonth before the battle, John Napier is de- signed our beloved household esquire ; and, by the expressions in the retour of his son and heir, the period of his death may be traced to the very day of the battle; * an interesting circumstance, as two of his lineal heirs-male fell successively at Flodden and Pinkie. His marriage to Elizabeth Menteith in- volves the history of the right to the earldom of Lennox, a subject fully discus- sed in the Lennox case for Merchiston at the end of the volume. His eldest son, Archibald Napier of Edinbellie, and fourth of Merchiston, belonged to the household of James IV. at the commencement of that reign. Of his career I have discovered few particulars, except that he married thrice, connecting himself each time with noble and distinguished families, Douglas, Crichton, and Glenorchy ; as more fully recorded in the genealogical note. There is a charter in the record of the great seal, 22d February 1494-5, by which James IV. confirms a charter of mortification, dated 9th Novem- ber 1493, for support of a perpetual chaplain (unius capellani perpetui) at the altar of St Salvator within St Giles’ Church of Edinburgh; grant- ed by Archibald Naper of Merchamstoun, with consent of Elizabeth Men- teith, Lady of Rusky, his mother; to pray for the souls of the Kings James I.

The sum mortified was ten merks yearly. Betwixt his second and third marriage occurred the battle of Flodden. Led by a barbarous love of arms, and a wild romantic spirit of chivalry, James IV., in the year 1513, determined to invade England. The voices of wisdom and superstition were blended to warn the infatuated monarch. But he was not to be stayed; and his folly sealed the fate of Scotland. It is well known that the devoted barons and gentry of the Lothians followed their so- vereign en masse, and were conspicuous in the very centre of the battle. The Earl of Bothwell led these chiefs and their retainers, who were placed imme- diately in the rear of the king’s division. After the four earls commanding the Scottish wings (Lennox, Argyle, Crawfurd, and Montrose,) were slain, the men of Lothian found themselves placed betwixt the victorious bands of Sur- rey and Stanley, where they fought and bled in vain. Still from the sire the son shall hear Of the stern strife and carnage drear : Of Flodden’s fatal field, Where shiver’d was fair Scotland’s spear And broken was her shield ! Archibald Napier escaped the carnage of that fatal day, and survived be- yond the year 1521. But his eldest son was left dead on the field. Sir Alexander (fifth of Merchiston) who fell at Flodden, was the only son of Archibald’s first marriage with Catherine Douglas; (a daughter of the illustrious houseof Morton and Whittingham,) and had obtained the honour of knighthood some years before his death. James IV. by a charter dated 2ist June 1512, erected the lands of Merchiston and others into a free barony in his favour, with all the consequent privileges, thus forming a second barony in the family. He married Janet, the eldest daughter of Edmund Chisholme of Cromlix, the same family from which his great-grandson, the philosopher, took his second wife. Their eldest son, Alexander sixth of Merchiston, was, upon the 11th of March 1513, infeft in the barony of Edinbelly-Napier, as heir to his father. The young laird was at this time an infant, having been born about the year 1509. He was the only son; and junior to both his sisters, Helen and Janet, the first of whom became the wife of Sir John Melville of Raith, and the other of Andrew Bruce of Powfoulis. 3 NAPIER OF MERCHISTON. Al When he was only about sixteen years of age, a conspiracy was entered into by some of his relations both against his purse and person, which may be no- ticed, as it introduces names of historical and romantic interest, and is moreover characteristic of the times. His mother, after the loss of her first husband, married Sir Ninian Seton of Touch and Tullibody, a baron of a well known and ancient house, who became the guardian of young Merchiston. His ma- ternal uncle was James Chisholme, (chaplain to James III.) who had been at Rome in 1486, and was at that time provided by Pope Innocent VIII. with the bishoprick of Dumblane. This prelate also took some charge of his nephew. Upon the 18th day of June 1525, a contract was concluded at Edinburgh, of which the parties were, on the one side, the Bishop of Dumblane, the Lady Seton his sister, her husband Sir Ninian for his interest, and the young laird of Merchiston; and on the other side, Archibald Douglas of Kilspindie, Isa- bella Hopper his wife, and Agnes Murray, the daughter of Isabella by a pre- vious marriage. This contract bears, that, in contemplation of a marriage to be solemnized, and hereby contracted between Alexander Napier and Agnes Murray, the former was to grant a receipt and discharge to Douglas, Isabella Hopper, and Agnes Murray, as if he had obtained from them the sum of 1200 merks as a marriage portion. That this sum was to be held in trust by the par- ties contracting, as a marriage portion for Janet Napier, the sister-german of Merchiston, whom failing, to his other sisters. Then follows a clause by which the young laird bound himself to grant to his mother and stepfather a full and free discharge of all intromissions whatever with his means and estate, up to the date of the fulfilment of the marriage betwixt him and Agnes Murray. There is no indication among the family papers that this marriage actually took place ; and upon the 23d September 1531, after he had become of age, Alexander Napier executed a deed of revocation, narrating this contract, and declaring that he had only become a party to it in consequence of the s¢nister machinations, and false information of his own relations. He therefore re- voked the whole transaction as done to his great prejudice.* The Douglas mentioned in this deed was the celebrated Sir Archibald Douglas of Kilspindie, + son of Archibald fifth Earl of Angus, (the great Earl, commonly called “ Bell * « Tn sua minorietate, ex sinistra machinatione circumuentus per certos suos consanguineos, fatebatur se recipisse.” &c.—Merchiston Papers. + “ Archibald of Kilspindie, whom he [James-V.] when he was a child loved singularly well for his ability of body, and was wont to call him his Gray-Steill,” [a champion of popular romance. ] — Godscroft. F AQ THE LIFE OF the Cat”) by his second wife, Catherine, daughter of Sir William Stirling of Keir. He was appointed high treasurer of Scotland, 29th October 1526, by James V., who was trained to manly exercises under his faithful care, which he ill-requited. Hume of Godscroft, (the historian of the house of Douglas, who wrote in the reign of James VI.) gives an affecting account of Kilspindie’s ser- vices and fate ; and Sir Walter Scott has immortalized him in the Lady of the Lake. Two years after the date of this revocation, Alexander Napier obtained a dispensation from the Pope for his marriage with his cousin Anabella Camp- bell, which deed, dated 9th October 1533, is still preserved among the family papers. It was the interest of the Church of Rome to throw as many obstacles as possible in the way of matrimony, in order to have the credit and the pro- fit of removing them ; and this dispensation proceeds upon the narrative, that the parties were related to each other within the fourth degree of consangui- nity. As the deed afforded no other clue to the family of Anabella Camp- bell, the late Lord Napier, in the progress of compiling the genealogy of his house, applied to the Earl of Breadalbane for information on the subject, and received the communication which will be found below. * Soon after his marriage Merchiston went abroad, and was much in foreign countries, latterly, it would appear, on account of his delicate state of health. The * « London, July 11, 1808. “ My Dear Lorp,—lI have endeavoured to collect every information I possibly could on the point you wished ; the result is from a memorandum I took when I was at Taymouth, after at- tentively examining Jamieson’s genealogical tree, as well as a book (manuscript) containing a his- tory and some anecdotes of the family of Glenorchy. It is as follows :— «¢ ¢ Sir Duncan Campbell of Glenorchy, who succeeded his father Sir Colin, in the year 1480, and was afterwards killed at the battle of Flowden in 1513, was, by his second wife, Mon- crieff daughter of the Laird of Moncrieff, father to John Bishop of the Isles, and to Catherine and Anabella Campbell. Catherine was married to the Laird of Tullybardine ; and Anabella to Napier of Merchiston, (the dates of these daughters’ marriages are not mentioned,) from whom was descended, Sir Archibald Napier, John Napier, and Archibald Lord Napier of Merchiston.’ “ T assure you it gives me great pleasure to find there is such an alliance between your Lord- ship’s family and mine ; and I have the honour to be, my dear Lord, your obedient humble Ser- vant,—BREADALBANE.” This genealogical information is confirmed by the following document, which Lord Napier had not observed among his papers.—“ 10¢h November 1554, &c.—The quhilk day ane honorabill man Archibald Naper of Merchamstoun [the philosopher's father] past to the personalie presence of ane honorabill lady and his ¢ratst consignate Kathryne Campbell Lady Tulyberdin, executrice and intromissatrice with the gudis and geyr of vmquhile ane honorabill lady, Dame Margaret Moncreif Lady Kers, and proponit, that becaus it wes cumin to his vnderstanding that the said NAPIER OF MERCHISTON. 43 royal licenses to travel, and charges to return, which he received under theprivy- seal and sign-manual of James V., are still preserved among the family papers. Upon the 18th and 28th September 1534, he obtained royal letters of license and protection, bearing that, ‘‘ We, for the guid, trew and thankfull seruice done to us be our louit, Alexander Naper of Marchamston, and Androw Bruss of Powfoulis, his guid bruthir,” &c. “ grantis and gevis licence to thaim to pas to the partes off France,” &c. for three years. The letters protecting his property in his absence narrate, that “ our weilbelouit Alexander Napar of Mercham- stoun is of our speciall licence to pass furth of our realm be sey or be land, for fulfilling of his pilgramage at Sanct Johne of Ameis in Fraunce,” &c. At this time France was the centre of attraction; and James V. not long after- wards went there himself on his matrimonial expedition. “ Here is to be remem- bred,” says Bishop Lesley, “ that thair wes mony new, ingynis and devysis, alsweil of bigging of paleicis, abilyementis, as of banquating and of menis be- haviour, first begun and used in Scotland at this tyme, eftir the fassione quhilk thay had sene in France.

The active career of James V. was now drawing to its melancholy close. In the year 1542 his barons deserted his standard at Fala; and refused, with one solitary exception it is said, to follow their ardent monarch across the border to invade England. So great was the disgust which he had occasioned to the chiefs of his army, that loyalty and love of arms was in abeyance with them all except Sir John Scott of Thirlestane, who possessed the estates of Thirlestane, Gamescleugh, &c. lying upon the rivers Ettrick, and including St Mary’s Loch at the head of Yarrow. This baron, amid the general disaffection, nobly de- clared, that he with his plump of spears would follow the king wherever he led; and one of the latest acts of James V. was to reward his feudal devotion by a charter of those arms, which are now quartered with the Lennox roses of Merchiston. j From fair St Mary’s silver wave, From dreary Gamescleugh’s dusky height, His ready lances Thirlestane brave Array’d beneath a banner bright. The tressured fleur-de-luce he claims To wreath his shield, since royal James, Encamp’d by Fala’s mossy wave, The proud distinction grateful gave, For faith ’mid feudal jars ; What time, save Thirlestane alone, Of Scotland’s stubborn barons none Would march to Southern wars ; And hence, in fair remembrance worn, Yon sheaf of spears his crest has borne ; Hence his high motto shines reveal’d «“ Ready, aye Ready,” for the field.* The disgraceful rout of Solway, which immediately followed, sealed the fate of the unhappy king; and the heart which had withstood the rude assaults of affliction from the death of his first consort, and of the two young princes whom his second had lately borne him,—which had been impervious to the voice of justice and mercy when he decreed the death of the Lady Glammis,— broke under the affliction of dishonour to his arms. * The Lay of the Last Minstrel. The heir of line of Merchiston is lineal heir-male of Thirle- stane ; Lord Napier being also Sir William Scott of Thirlestane, Bart. and possessor of that estate. 46 THE LIFE OF Alexander Napier could not have been disloyal.* It seems that he had never recovered the fever by which he was attacked abroad ; and that in the second year of the new reign he again settled his worldly affairs, and obtained leave from the regent to go abroad for a twelvemonth. The letters run in the queen’s name in these terms :—“ REGINA.—We, with aviss and consent of oure derrest cousing and tutour, James Erle of Arrane Lord Hamiltoun, protectour and gouernoure of oure realme, understanding that oure louit Alexander Naper of Merchamstoun is vexit with infirmiteis and seikness, of the quhilkis he may nocht be gudelie curit and mendit within oure realme.

He departed to be cured by the cunning leeches of a foreign land ; and he returned to lose his life in one of those memorable battles which form such melancholy chapters in the history of Scotland. He fell at the battle of Pinkie in September 1547, when the Earl of Somerset inflicted another defeat upon the chivalry of our country. The circumstance * Alexander Napier had certainly returned to Scotland after the king’s letter. Among the family papers is a summons raised by him to effect redemption of a dwelling-house which his grand- father Archibald had sold under that conditional clause, to “ Andro Bishop of Murray.” The de- tails of what was then considered a great mansion are curious. “ All and hale his [ Napier’s] grete mansion, contenand hall, kecheing, loft abone the kecheing, pantre, and loft thairabone, than oc- cupit be maister Jasper Cranstoun, the chapell and three sellaris, with ane litill hous callit the pre- sone, and all thair pertinentis, liand within oure burgh of Edinburgh, on the north side of the street of the samyn.” The summons is dated 16th October, first year of the reign of “ Marie, be ye grace of God Quene of Scottis,” ¢. e. in 1543, when she was precisely ten months old; and is directed against “ Patrick, now bishop of Murray, Ge maister Henrie Lawdre our advocat.” NAPIER OF MERCHISTON. AZ of Alexander Napier falling in this battle is mentioned in the confirmation of his will by Anabella Campbell his widow. * Among the Merchiston papers there is an interesting charter, alluding to the death in battle of the two Alexander Napiers, in relation to the following circum- stances: Mathew Stewart, fourth Earl of Lennox of the usurping line, became after the death of James V. the rival candidate with the Earl of Bothwell for the affec- tionsof thequeendowager. Buthaving warmly embraced the project ofan alliance betwixt the young Queen of Scots and Prince Edward of England, and taken arms in support of the English interest, he was compelled on the failure of that matrimonial scheme, to fly to England. He signed a secret convention with Harry VIII. in June 1544; and in August following was sent into Scotland with a hostile fleet and army. For this and other treasonable delinquencies, he was forfeited in Parliament 1545. The Napiers of Merchiston, as we shall have occasion more particularly to notice, held of the Earls of Lennox the lands of Blairnavaidis and Isle of Inchmone in Lochlomond, with valuable pertinents and privileges, as a compensation, by way of excambion, for higher interests in the fief usurped by those Earls. As the earldom of Lennox fell into the hands of the crown by this temporary forfeiture, the vassals required to have their respective grants renewed or confirmed to them by the sovereign. It would appear that Haldane of Gleneagles, taking advantage of the confusion of the times and the minority of Archibald Napier, obtained a grant of the lands of Blairnavaidis &c. to the exclusion of the Merchiston family. In the year 1558, however, before the Earl of Lennox was restored, and shortly after the marriage of Queen Mary to the Dauphin, that princess issued a charter, revoking the one she had granted to Gleneagles, and reinstating the family of Merchiston in their patrimonial rights. The precept of sasine un- der the great seal of Queen Mary is dated 14th July 1558, and narrates, that the lands of Blairnavaidis, eister and wester, with the Isle of Inchmone, and the right of fishing over the whole of the lake of Lochlowmond, (in lacu de Lochlowmonde,) &c. which belonged to Archibald Naper, holding of Mathew late Earl of Lennox, and which have fallen into our hands by reason of escheat and process of forfeiture against the said Mathew, &c. and which, after the decree of forfeiture we, in our minority, had granted by charter un- der our great seal to James Haldane of Gleneagles, his heirs and assignees,— * See the series of family wills in the Appendix, No. IV. 48 THE LIFE OF and which lands and islands having again fallen into our hands by reason of our general revocation made in our last Parliament,—and we considering that the predecessors of the said Archibald Naper had obtained the said lands in ex- cambion from the predecessors of the said Mathew late Earl of Levenax,—so that they may have regress to their first excambion, and also because the said Archibald and his predecessors were in no manner of way participators in the crimes of the said Mathew late Earl of Levenax, but were innocent of the same ; * and that they in all past times have faithfully obeyed the authority of our realm, even to death, and have, under the standard of our dearest grand- . father, and under our own, in the battles of Flowdoun and Pinkie, been slain ; —therefore, and for other good causes moving us, we, after our general revo- cation in Parliament, have of new given and granted to the said Archibald © Naper of Merchanstoun, his heirs and assignees, the said lands of Blairnavaid- dis, eister and wester, isle, fishing,” &c. : Archibald Napier, seventh of Merchiston, to whom this charter was grant- ed, was the eldest son of Alexander killed at Pinkie, and Anabella Campbell. At the time of his father’s death, Archibald had not completed his fifteenth year. On the 8th November 1548, he obtained a royal dispensation enabling him, though a minor, to feudalize his right to his paternal barony, in contemplation, it would seem, of his marriage to Janet Bothwell, the mother of our philoso- pher, which occurred in or before the year 1549. {+ The connection was highly eligible, though from his extreme youth it might have involved some impru- dent step. John Napier, however, had no reason to blush for his maternal descent. Archibald Napier’s father had an intimate friend in Francis Bothwell, one * The words are “ac nos considerantes predecessores dicti Archibaldi Naper predictas terras in excambium de predecessoribus dicti Mathei olim Comitis de Levenax habuerunt, sic, quod regres- sum ad eorum primum excambium haberent ; et quod dictus Archibaldus et sui predecessores nullo modo seu pacto participes cum iniquitate dicti Mathei olim comitis de Levenax fuerunt, sed innocentes de eadem erant, et quod ipsi omnibus temporibus retroactis authoritati regni nostri fide- liter servierunt, wsque ad eorum decessum, et quod sub vexillo quondam charissimi avi nostri et nostro vexillo in bellis de Flowdoun et Pinke occisi fuerunt ; idcirco,” &c. t His retour runs in the name of the young Queen of Scots and bears, “ quod est legittime etatis per dispensationem nostrum cum consensu et assensu nostri charissimi consanguinei Jacobi comitis Aranie Domini Hamiltoun nostri tutoris et gubernatoris,” &c. NAPIER OF MERCHISTON. AQ of the most respected and distinguished burgesses of Edinburgh in the reign of James V. In one of Alexander Napier’s testaments, he names Francis Both- well sole tutor of his eldest son, failing the administration of his widow Ana- bella Campbell. Bothwell, however, died before the battle of Pinkie; and the tu- torial charge of young Merchiston devolved upon his uncle Sir William Mur- ray of Tullibardine, James M‘Gill of Rankeillor-nether, and John Forrester of Logie. At the tender age of fifteen, or thereabouts, this interesting minor was united to Janet Bothwell, the daughter of his father’s friend, and of Katherine Bel- lenden, only daughter of Patrick Bellenden and Mariota Douglas, and sis- ter of the distinguished Thomas Bellenden of Auchinoul, Justice-Clerk and Director of the Chancery to James V. A notice of the Bothwell family in Nisbet’s Heraldry records, that Francis Bothwell “ married Janet, one of the two daughters and co-heirs of Patrick Richardson of Meldrumsheugh, and got with her these lands lying within the regality of Broughton, and shire of Edin- burgh. He had by his wife two sons and one daughter: Richard, who was provost of Edinburgh, and allied in marriage with the house of Hatton; Mr Adam Bothwell, the second son; and Janet, who was married to Sir Archibald Napier of Merchiston, mother by line to the honourable and learned mathe- matician, John Napier of Merchiston, inventor of the logarithms.” In tra- cing this family, however, through the old records of the city of Edinburgh, I detect a fact not observed by any genealogical writer, that the mother of this celebrated prelate Adam Bothwell Bishop of Orkney, and the grandmother of our philosopher, was not the heiress of Meldrumsheugh, as hitherto sup- posed, but Katherine Bellenden of Auchinoul.* No record could more fully * One of the ancient protocol books bears an entry to this effect, that William Bothwell, bur- gess of Edinburgh, acting as bailie for James Mailville, son and heir of the late James Mailville, burgess of Kirkaldy, lord of Dunsyre in the barony of Bothwell, and shire of Lanark, gives sei- sin at the east town of Dunsyre to the attorney of Adam Bothwell Bishop of Orkney, proceed- ing on a precept of clare constat, which narrates, that ‘“ clare constat et est notum quod quond. Magister Franciscus Bothwill, burgensis burgi de Edinburgh, et Katherina Ballinden, ejus sponsa, pater et mater reverendi in Christi Patris Adami Bothwill, miseratione divina episcopi Orchaden- sis, latoris presentium ; obierunt ultimo vestiti et sasiti ut de feodo in conjuncta infeodatione de omnibus et singulis terris ville orientalis de Dunsyre, &c. et quod dict. reverendus pater est legi- timus et propinquior heres eorundem quond.

A remnant of theancient Books of Adjournal of the High Court of Justiciary, preserved among the MSS. of the Advocates’ Library, solves this question also. Ina trial of the magistrates of Edinburgh, of date 22d March 1566, for setting a prisoner at li- berty who had committed “ slauchter ;” Sir Archibald Napier, the philosopher’s father, is one of the prosecutors, while Sir John Bellenden officiates as jus- tice-clerk, having also a seat on the bench. An objection is taken for the pan- nels by Mr David Borthwick, who “ allegit that the justice-clerk mycht nocht be clerk in this mater, nor voit thairintill, becaus he and the lard of Mer- chamestonis wyfe wes sister and brethir bairnis, and that thair wes bairnis be- tuix the said lard and his spous.” ‘This proves that Katherine, the only sister of Sir Thomas Bellenden of Auchinoul, was the grandmother of John Napier ; for that lady unquestionably was the aunt of Sir John Bellenden, who succeed- ed his father, Sir Thomas, as justice-clerk. It can be proved, however, from various sources, that this Katherine Bellenden was the wife of the famous Oli- ver Sinclair, whose ill-fated elevation in the affections of James V. led to the untimely death of that monarch. But the difficulty is removed by an expres- sion in a letter (to be afterwards quoted) of the Bishop of Orkney to Archi- bald Napier in 1560, wherein he mentions “ Olyfer Sinclair, my gud-father.” Thus, by a very accidental chain of conclusive evidence, the maternal descent of John Napier is, for the first time, completely cleared.* Our philosopher’s mother must have been reared in the family of this unfor- tunate minion of James V. It is also worthy of remark, that by other near re- latives of Merchiston, the same monarch was attended and soothed at the mo- ment the news reached him of the defeat of his favourite at Solway. Helen Napier, eldest daughter of Sir Alexander killed at Flodden, had married Sir John Melville of Raith, who was particularly distinguished in the reign of James V., and one of the early Protestant martyrs of the Reformation in Scotland.t+ * See Note (B) as to the Bothwells and Bellendens. + He was beheaded by the Catholic faction in 1548, although the most honourable and inno- cent statesman of his country. An old MS. history thus records the death of “ Johnne Meluill, ane nobill man of Fyff, quho was ane of the king’s most familiaris, quhois lettres send & writtin to ane certane Englisman, recommending re him ane freind of his takin pressoner, war inter- NAPIER OF MERCHISTON. 51 Their daughter Janet, thus the cousin-german of our philosopher’s father, be- came the wife of Sir James Kirkaldy of Grange, high treasurer of Scotland. Towards this lady and her son William, so remarkably celebrated as the champion at once of the Reformation and of Queen Mary, James V. en- tertained the same affectionate regard with which he honoured the trea- surer; and the most friendly intercourse seems to have passed betwixt the monarch and these cousins of Merchiston. It was to their residence in Fife that he first betook himself, accompanied by young William Kirkaldy, upon hearing of the rout of Solway. Grange was from home; but his lady received her sovereign (conducted by her son) as became one in whose veins flowed the united loyal blood of Melville of Raith, and Napier of Merchiston ; and who was, besides, the spouse of his best and most faithful councillor. She exerted herself to calm his ruffled spirits, and to persuade him to take nourish- ment. During supper, she endeavoured to sooth and comfort him by every means in her power. “ It is the will of God,” said the good lady, “ take not his will amiss.”——“ My portion,” was his reply, “ of this world is short. I will not be with you fifteen days.” His servants tried to rouse him with the idea of festivities. ‘‘ Where shall we prepare for the approaching Christmas,” said they ; to which the king answered, with a smile of derision, “ Choose your place ; but this I know, before Christmas arrive you will be masterless, and the realm without a king.” Shortly after, he went to his own palace of Falk- land, where he lay down to die. ‘Those around endeavoured once more to rouse him with the intelligence, that his queen was safely delivered of a fair daughter. “ A daughter,” said the dying monarch, and turned his face to the wall, “ the devil go with it; it will end as it begun; it came from a woman, and it will end with a woman.”* After that, continues John Knox, who pro- bably had all the particulars from his intimate friend William Kirkaldy, he spake not many words that were sensible, but ever harped on his old song, * Fy fled Oliver ? Is Oliver taken ? All is lost.” Thus prominent, in one of the most interesting scenes of the history of the Stuarts, were the near relatives of Archibald Napier and Janet Bothwell, a few ceptid.

Francis Bothwell, the father of John Napier’s mother, is a worthier object of historical reminiscences than her stepfather. For many years he presided over the councils of his native town, and aided those of the state, both legisla- tive and judicial, with an honest energy of character and talents that had fallen on evil times. At the period of the battle of Flodden, when the magistrates and citizens of Edinburgh distinguished themselves both by their devotion in the field, and by the wisdom and firmness with which they met and provided for the exigencies of a moment so fatal to the independence of Scotland, Both- well ranked foremost among his fellow-citizens. In the course of the period betwixt the years 1514 and 1524, he passed successively through all the dig- nified civic offices during the unpopular regency of Albany. One curious feature in the history of the manners and the times is display- ed in the fact that, while the country was torn with war and scourged with fearful visitations of pestilence, and while at a moment’s warning the very gutters of Edinburgh were apt to run red with the best blood of Scotland, the citizens of the highest class lent themselves to promote a species of saturnalia or unruly games, which not unfrequently added to the savage turbulence of the times. Yet some of the graver and wiser citizens expressed a distaste for these dangerous gambols, refused their countenance to the play, and declined the elevation pressed upon them of being masters of the revels. Such recusants, however, were only regarded as traitors to Momus, and an extraordinary power seems to have been exercised by the town-council over any member of the community who attempted to evade the crown and sceptre of misrule. He was liable to heavy fines, which were rigorously exacted, even to the ex- tent of attaching his property. Francis Bothwell accepted the dignities of bailie, “ magister societatis,” dean of guild and provost of Edinburgh ;—but that of “ Litil John,” to which in 1518 he was elected, being not agreeable to his habits and tastes, he declined to accept, and was actually constrained to peti- tion the Earl of Arran, at that time provost of Edinburgh, for a remission from the duty imposed upon him, and from the consequences of his non-acceptance. It must have been a sight truly ludicrous to behold some dignified and thought- ful bailie, such as the grandfather of our philosopher, his heart full of disgust and foreboding, making sport to the rabble, and kicking his heels perforce, NAPIER OF MERCHISTON. 53 under some fantastic dress, amid the merriment of his more jovial brethren and the shouts of the assembled populace. The old record of Bothwell’s escape from figuring in this tyrannical mummery, affords so curious an illustration of the customs and manners of the day, that I shall give it here in the quaint terms of the original :* “17 April 1518, the 12th hour.—The quhilk in pre- sence of the president, baillies, counsall and communitie, Maister Frances Boithwell producit my Lord Erle of Aranis principall provest’s writingis and charge, till excuse him fra the office of litil Johne to the quhilk he was chosen for this yeir, desyrand the samyn to be obeyit and the tenour thairof to be incertit in this instrument, the quhilk tenour of the said writing followis: “ President, ballies and counsall of Edinburgh we greit you weill; It is un- derstand to us that Maister Francis Boithwell your nichtbour, is chosin to be litil Johne for to mak sportis and joscositeis in the toune, the quhilk is a man to be usit in’hiear and gravar materis, and als is apon his viage to pas beyond sey his neidfull erandis ; quharfor we request and prayis, and als chargis you that ye hald him excusit at this tyme, and we be this our wrytingis remittis to him the law, gif ony he has incurrit for none excepping of the said office, dis- charging you of ony poynding of him tharfor.

In the “ Register of the proceedings of the Burrow Court and Court of Consale of Haidinton,” embracing the period betwixt 28th June 1530, and last day of April 1555, the following entries occur, which show that this custom was in full vigour more than twenty years after Francis Both- well’s appointment in Edinburgh. 1540, March 30.—“< The which day the bailies and commu- nity ordain, that whoever be made abbot this year, that he shall take the same on him within 24 hours next after they be chosen and charged therewith : or then to refuse the same, and pay their 40 shillings ilk ane after other as they refuse ; and this to be observed in time to come.

He appears in the rolls of Parliament, 16th November 1524, as a commissioner of the burghs, and was then chosen one of the Lords of the Articles ; again on the 10th July 1525, and on many other occasions. On the 7th June 1535, he appears as one of the royal commissioners to Parlia- ment, and also one of the commissioners for the city of Edinburgh. He was again chosen on the Articles, and appointed by the barons one of the commis- sioners for the tax granted to James V. on his marriage.* But not the least of his honours was having been selected as one of the fifteen upon the insti- tution of the College of Justice. The Court was for the first time assembled in presence of his majesty on the 27th May 1532, and their sittings have con- tinued ever since at the appointed times, except when occasionally interrupted by war, pestilence, or usurpation. Francis Bothwell was among the number of “ cunning and wise men” chosen for the temporal side; while on the spiri- tual, the person who had the honour of being named first after the Lord Chan- cellor and president, was Richard Bothwell, his younger brother. From every line of his descent talent seems to have flowed in upon John Na- pier. His granduncle Richard being bred to the church, was made prebend of the Cathedral of Glasgow, and afterwards appointed rector of Eskirk or Ash- kirk, a parish in the presbytery and shire of Selkirk, and diocese of Glasgow. He was director of chancery to James V. not long before another granduncle of our philosopher’s, Sir Thomas Bellenden, held that office in the same reign. + He appears as one of the royal commissioners for fencing or opening Parlia- * Act Parl.

Sir William Eure appeared for Henry, and Mr Thomas Ballenden and Mr Henry Balnavis for the Scottish king. This affair, of little mo- ment in itself, is connected with an important letter from Eure to the lord privy-seal of England, in which he narrates some conversations with Ballenden, a man of aged experience and eminent abi- lities, concerning the court and character of James, on which they reflect a new and strong light.” This was Sir Thomas Bellenden, our philosopher’s grand-uncle. Thus both his grand-uncles, of separate stocks, were successively directors of the chancery to James V., and very able men, NAPIER OF MERCHISTON. 55 ment in August and December 1534, was chosen one of the Lords of the Ar- ticles for the clergy on the 7th June following, and on the 12th of that month was appointed, by his brethren of “ the spiritualitie,” one of their commissioners for the taxation granted by the three estates to the king on his marriage. He was also doctor of the civil and canon laws, and provost of the church of St Mary in the Fields, which became so infamously unhallowed by the name of Kirk-of-Field, as the place of Darnley’s murder.

When we consider the state in which he found scientific theology, and the passions and prejudices which surrounded his subject, we must be struck with the wonderful resources of his clear and powerful intellect, so far in advance of his time. It was compara- tively easy, with such an example before him, for the learned Mede to compose his ponderous treatise. Nor can we help surmising that the “ Clavis et Com- mentationes Apocalyptic” derived a hint at least from Napier’s declaration, that he considered his own exposition imperfect, and merely as paving the way for more extended commentaries in Latin. In Mede’s celebrated work a method has been adopted with regard to the order and connection of the apocalyptical visions, the principal of which the author thus explains :—“ The Apocalyse, considered only according to the naked letter, as if it were a history and no prophecy, hath marks and signs sufficient, inserted by the Holy Spirit, whereby the order, synchronism, and sequel of all the visions therein contained may be found out and demonstrated, without supposal of any interpretation whatsoever. This order and synchronism thus found and demonstrated, as it were by argumenta intrinseca, is the first thing to be done and forelaid as a foundation, ground, and only safe rule of inter- pretation, and not interpretation to be made the ground and rule of it.”. The editor and biographer of Mede says:* “ The glory of the first discovering these synchronisms is peculiarly due to Mr Mede; and upon this score shall the present and succeeding ages owe a great respect and veneration to his . memory,” &c. But we must do our own philosopher the justice to observe, that, long before Mede, he adopted that very principle (though in a form so simple and unaffected that those who run might read) for the developement of his plain discovery. To each of his treatises tables are attached, occupying a single page, and where at a glance, the nature, order and connection of the whole Revelations may be discovered. He fixes the essential synchronisms, both of dates and terms, in his preliminary propositions ; and has even done so in an instance where Mede had failed. “ Mr Mede,” says Sir Isaac, “ hath explain- ed the prophecy of the first six trumpets not much amiss; but if he had ob- eminebat, res difficillimas methodo certa et facili quam paucissimis expedire.’—Preface to the Canonis Constructio edited by Robert Napier, 1619. * See the Life of Mede and account of his works at the commencement of the volume already referred to. 192 THE LIFE OF served that the prophecy of pouring out the vials of wrath is synchronal to that of sounding the trumpets, his explanation would have been yet more complete.” * Now Napier carries this synchronism so far, as in his second proposition to “ conclude both those trumpets with those vials, and also the rest of the trumpets with the rest of the vials respective, in purpose, meaning, time, and in all other circumstances to be one and the self-same thing.” + That the best part of all the celebrated apocalyptic commentators who are quoted and looked up to in modern times is to be found in Napier, might be proved by a series of comparisons of the important passages in each, chronolo- gically arranged. This would far exceed our limits. ‘The object, however, being to assert his right to the throne of scientific theology in Scotland, no less than of mathematical science; and his right of priority at least over Mede and the Newtons, it is hoped that a few more comparisons will be excused. The department of Sir Isaac Newton’s theological works in which he is held to be most original and profound is hissystem of chronology. “ Among thechro- nological writings of Sir Isaac Newton,” (says his biographer, Brewster,) “ we must enumerate his letter to a person of distinction who had desired his opinion of the learned Bishop Lloyd’s hypothesis concerning the form of the ancient year. ‘This hypothesis was sent by the Bishop of Worcester to Dr Prideaux. Sir Isaac remarks, that it is filled with many excellent observations on the an- cient year ; but he does not “ find it proved that any ancient nations used a year of twelve months and 360 days without correcting it from time to time, by the luminaries, to make the months keep to the course of the moon, and the year to the course of the sun, and returns of the seasons and fruits of the earth,” &c.{ In like manner Sir Isaac, in his “ chronological observations upon the years used by Daniel,” has these observations.

NAPIER OF MERCHISTON. 193 eastern nations consisted of 12 months, and every month of 30 days: and hence came the division of a circle into 360 degrees. This year seems to be used by Moses in his history of the flood, and by John in the Apocalypse, where a time, times, and half a time, 42 months, and 1260 days, are put equi- pollent. But in reckoning by many of these years together, an account is to be kept of the odd days which were added to the end of these years. For the Egyptians added five days to the end of this year ; and so did the Chaldeans long before the times of Daniel, as appears by the era of Nabonassar : and the Persian magi used the same year of 365 days, till the empire of the Arabians. The ancient Greeks also used the same solar year of 12 equal months or 360 days; but every other year added an intercalary month, consisting of 10 and 11 days alternately.” How many are there (such as Sir David Brewster) well acquainted with all these passages in Sir Isaac’s works, who are yet not aware that the Scotch philosopher had the sagacity to perceive in his subject the necessity of clear- ing the very matter which, a hundred years afterwards, came under the consi- deration of such men as Newton, Lloyd, and Prideaux: and that he did so in words very nearly the same, and certainly as distinct as those of the great Eng- lish philosopher. Napier’s 15th proposition contains the very synchronism quot- ed above. He says “ The 42 months, a thousand and twohundreth and threescore prophetical days, three great days and a-half, and a time, times, and half a time, mentioned in Daniel and the Revelation, areall onedate;” and thenenters intothe details, in nearly the words and order observed by Sir Isaac Newton, but perhaps with still greater precision. “ Every month among the Grecians contained thirty days precisely,” &c. “ twelve months in the year, and thirty days in every month,” &c. For confirmation whereof it is to be understood that the first institutors of time, to wit the Chaldeans, Grecians, and astrologers, in their directions do agree with this description of time ; for they divide the equinoc- tial into 360 degrees, and attribute a year for every degree of their directions, whereby the whole time of the great revolution or direction of the whole equi- noctial will be 360 years,” &c. “ But now although it is proved these dates to be 1260 years, yet forasmuch as 1260 of Grecian years are but 1242 Julian years, and 8 months or thereabout ; and 1260 Julian years are 1277 and a half of Grecian years, making thereby near 18 years difference; it rests therefore to prove what kind of years these be. These, we say, are common Julian years for two causes. rst, although the Grecian common year con- tained but 12 months, and 30 days in every month, yet do they adjoin certain Bb 194 . THE LIFE OF intercalar days, which doth make every year overhead to contain 12 months, Jive days and a quarter, which is 365 days and a quarter ; and so consequent- ly are overhead equal with our common Julian year. Secondly, among the Hebrew prophets, where a day is taken for a year, although the common year contain but 12 months, yet almost every third year, they adjoined an inter- calar month by doubling the month Adar, which made their Hebrew years overhead equal also with our Julian years,” &c. The similarity apparent in the train of thought of these two chief philoso- phers of the sister kingdoms is very interesting, and has been little observed. * Know youthe meaning,” (says Sir Isaac in the postscript of a letter to Locke,*) “ of Dan. x. 21,—there is none that holdeth with me in these things but Mich. the Prince ?” Napier, too, saw the propriety of a commentary upon this name, and Newton might have found in the Plain Discovery a dissertation upon the very question he put to Locke. Napier says, “ Michael is taken for one of the persons of the Trinity,” &c. “ with the name of Michael,—which is to say, who ts like God, or otherwise Deus percutiens, a beating or striking God,—doth both the person of Christ and the Holy Spirit agree,” &c. “ The question, there- fore, is, which person of the Deity doth Michael signify?” &c. and then, through proofs which it is unnecessary to quote, Napier arrives at the conclusion, that the Michael of Daniel and St John is the Holy Spirit that helped Christ, and not Christ himself. Sir Isaac devotes the second chapter of his commentaries to “ the propheti- cal language,” of which he there affords the key. Upon this M. Biot ¢ re- marks very justly, that Newton is not original in the idea or nature of these ex- planations, though he is so in the plan of establishing his glossary by a prelimi- nary chapter, which enables him afterwards to make aquicker progress by simply placing a prophetical term beside its explanation. Napier has not adopted this plan; but that arises from the circumstances, that his work is more thoroughly digested,—more systematically and philosophically arranged,—and more com- plete in all its parts than Newton’s. The commentaries of the latter consist of desultory essays upon certain points, and are therefore called “ observations” merely. He could have made no progress had he not, in the first instance, given his explanations of the prophetical language, as he must otherwise have paused to explain at every step of his observations. But Napier, after his thirty-six fundamental propositions, gives the whole version of the Apocalypse * See Newton’s Correspondence with Locke, published by Lord King. + See Biot’s Life of Newton, in the “ Biographie Universelle.” NAPIER OF MERCHISTON. 195 parallel with the paraphrase and application ; and then supports his interpre- tation of the text with notes and illustrations. In this manner there is a glos- sary to each of the chapters, and he explains all the terms and figures even more minutely than Newton has done. The English philosopher seems to have followed precisely the same explanations, as the curious may see by com- paring their respective works. Newton commenced his observations on the Apocalypse by declaring, that “ the folly of interpreters hath been to foretell times and things by their pro- phecy, as if God designed to make them prophets ;” and that the only legiti- mate province of human interpretation was to illustrate the prophecy when fulfilled, by comparing it with the event. Now this is precisely the nature, generally, of Napier’s work, and Newton’s censure has no application to him. For the English philosopher expressly admits, (in a passage we have quoted.) that a time of “ understanding,” 2. e. of foretelling the actual approach of the latter day was nigh ; and certainly he could not mean that that knowledge was only to be exercised after the event had arrived. And even with regard to his preliminary caution, it did not escape the Catholic eye of his biographer Biot, (though the Protestant one of Brewster might wink at the inconsistency,) that Newton “ entrainé lui méme au de la limites quwil avait d’abord assig- nées aux interpretes, il se trouve aussi predire comme eux lepoque de la chute, au du moins du declin de cette domination temporelle.” Our own philosopher, who gathered from the signs of his times that the end was at hand, must, therefore, upon the principles laid down by Sir Isaac Newton himself, stand exonerated in hazarding a calculation which, amid the erudition and practical Christianity of his work, is like a spot on the sun. * One effect of that work in his own country is very perceptible,—namely, the impulse it gave to the train of theological learning which succeeded it ; but from all connection with which Dr M‘Crie has tacitly excluded him. * Jt is curious to observe the coincidences betwixt Napier and Newton. When the Protestant privileges were attacked by James II., who endeavoured to force an unlettered monk upon Cam- bridge, Newton, who was a great Protestant champion there, was chosen to be one of the dele- gates sent to remonstrate, which they did with success. This forms a pendant to Napier’s mis- sion to James I. Then both philosophers viewed the Apocalypse through a mental eye of the same construction, and put forth commentaries. I do not think Newton ever read the Plain Dis- covery, yet some of his pages seem as if borrowed from it. Newton arranged a chronology for himself. Napier declared it was his intention to do so. Napier explained his Logarithms by the idea of lines generated by moving points, “ fluxu puncti.” Newton, too, regarded lines as gene- rated by the motion of points, and thus arrived at what he termed uations. 196 THE LIFE OF Napier’s friend and pastor, Robert Pont, was, like the philosopher, impressed with an idea that the world was departing,—that the hour of understanding was come. But he too was gifted nevertheless with a powerful and pene- trating intellect, was not carried by his own imaginings, and possessed a mind as composed as if it never wandered from its mathematical demonstrations. The consequence was, that he in like manner produced works in aid of theolo- gical science, seasoned, no doubt, with a sprinkling of mysticism, but charac- terized by- profound and philosophical learning. These are written with the same view, and in the very tone of the Plain Discovery; issued from the same press when Napier’s Commentaries were in their first repute; and pro- bably were matured under his advice and inspection. In 1599, Pont’s chronolo- gical work made its appearance, entitled, “ A newe treatise of the right reckon- ing of yeares and ages of the world, and men’s lives, and of the state of the last- decaying age thereof this 1600 yeare of Christ,” &c. In imitation of his friend, he sets forth this treatise in a series of propositions, supported precisely in the same manner, with condensed but recondite dissertations. He prefaces, too, that the exigencies of the times “ moved me to publish this treatise in our English tongue ;” and he refers, like Napier, “ to my more ample discourse to be set out in Latine.” He also arrives at within one year of the same conclusion as to the duration of the world, and gives it very nearly in our philosopher’s words. The seventh and last trumpet, says he, “ will extend to the year of Christ 1785 years, if the world shall continue so long. But the time, by great probabilitie and good arguments, is to be abbreviate for the elect sake.” And when he comes to illustrate his propositions with the mysteries of the Apo- calypse, he says, “ Whereanent I wil remit the readers to the profound and learned Commentaries of John Naper upon the Revelation, wherein the acci- dents of everie particular period of time, both in the one estate and the other, are set out at large.” It was not until the year 1619, after Napier’s death, that Pont brought out his more elaborate Latin treatise entitled, “ De Sabba- ticorum annorum periodis chronologica a mundi exordio,” &c. a work of great learning, and worthy of the high reputation of this “aged pastour in the Kirk of Scotland.” In this, too, he leans upon Napier ; “ Ut recté observat Naperus, et cum eo alii docti;” and calls him, as we have elsewhere noticed, “ Apprimé eruditum amicum nostrum fidelem Christi servum.” But the success of Napier’s Commentaries seems to have excited the Scot- tish bishops and Episcopal divines to similar attempts ; and he was followed, NAPIER OF MERCHISTON. 197 at no distant period, by Patrick Forbes of Corse,* afterwards Bishop of Aber- deen, and William Cowper, Bishop of Galloway. The production of the for- mer is a long dull argument of 256 quarto pages, critical rather than learned, and written in such barbarous English as to be nearly unintelligible. The version of the Apocalypse is not given; and we look in vain for the phi- losophical arrangement, the varied illustrations, and the beautiful practi- cal expositions of Napier’s Plain Discovery. Like that, it commences with an “ Epistle Dedicatorie” to King James, (but a very fulsome production,) and with an address to the Christian reader. It is decidedly a step backwards, and not in advance, from the mode of investigation developed by our philosopher. The Commentary by the Bishop of Galloway is a most respectable monu- ment of the theological science of the age, and a much more readable produc- tion than the work of Forbes ; being clearer, less verbose, and in good English. It is a mere sermon, however, or series of discourses, as compared with Na- pier’s. It is rich, however, in a gem of a commendatory poem, which we cannot resist quoting, both from its beauty and the name that owns it. To this admired discoverer give place, Ye who first tam’d the sea,—the winds outran,— And matched the day’s bright coachman in your race, Americus,—Columbus,—Magellan. It is most true that your ingenious care And well-spent pains, another world brought forth For beasts, birds, trees, for gems and metals rare, Yet all being earth, was but of earthly worth. He a more precious world to us descries, Rich in more treasure than both Inds contain,— Fair in more beauty than man’s wit can feign,— Whose sun sets not, whose people never dies. Earth should your brows deck with still verdant bays, But Heaven crown his with stars’ immortal rays. “ Master William Drumond of + Sawthorn-denne.” * « An learned Commentarie upon the Revelation,” &c. “ by Patrik Forbes of Cotharis, printed at Middleburg by Richard Schilders,” 1614. Dr M‘Crie has not overlooked him. “ The most learned of the divines who embraced Episcopacy received their education during this period. Patrick Forbes of Corse, the relation and scholar of Melville, and who afterwards became Bishop of Aberdeen, wrote an able defence of the calling of the ministers of the Reformed Churches, and a Commentary on the Reyelation.”—Life of Melville, ii. 316. + The celebrated poet and historian. It may be presumed that Sawthorn is a misprint for Hawthorn. 198 THE LIFE OF The most interesting pages of the bishop’s volume are the short notices he has given of the writers upon the Apocalypse whose works he had consulted. From this we may perceive that Napier had many ‘imitators both in Britain and abroad. Of our philosopher he thus speaks: “ John Napeir, Laird of Merchistoun, our countryman; worthily renowned as peerelesse indeed for many other his learned workes, and specially for his great paines taken upon this book out of rare learning and singular ingene, which are not commonly found in men of great ranke. Cotterius gives him great praise, but takes it backe again too suddenly to himselfe. He compares the Revelation to a golden mine. Natperus aurifodinam invenit, Vignerus ostendit, Ego vero aurum inde erui. Naiper found it,—Vigner hath shewed it,—but I (saith he) ‘have digged and wrought the gold out of it. He hath resolved this booke by a marveillous artifice, that it is not unlike a building standing upon six and thirty proppes or pillars. These are his propositions, so ingenuously indented, and combyned one with another, that the fall of oue imports the destruction of all. Most certaine it is, that his paines have been exceeding profitable for the discovering of many hard and obscure places of this prophecie.” * It is perfectly obvious then, that Napier must be regarded as the illustrious founder of that best school of scientific theology which Bacon desiderated in his Augmentis Scientiarum. We claim for our countryman this honour, even before Mede, Sir Isaac Newton, and Bishop Newton; and, considering his priority and originality, would be entitled to do so even if his Plain Discovery could not bear a strict comparison with their commentaries. * « Pathmos, or a Commentary on the Revelation,” &c. “ by Mr William Cowper, Bishop of Galloway. London, 1619.” Nor has Dr M‘Crie overlooked him. He says his discourses “ are superior to perhaps any sermons of that age. A vein of practical piety runs through all his evangelical instructions,—the style is remarkable for ease and fluency,—and the illustrations are often striking and happy. His residence in England may have given him that command of the English language by which his writings are distinguished.”—Life of Melville, ii. 316. Yet Na- pier’s Commentaries display a more nervous style than Cowper's, and excel them in every thing else.. Dr M‘Crie, however, had not observed Cowper’s Commentaries, which is a pity, as it would have led him to Napier’s. He narrates an amusing anecdote of this Bishop. An old Presbyte- rian woman came from Perth to Edinburgh to scold him for taking a bishoprick. She found the Bishop in state, in a fine house. “ Oh, Sir, what’s this? And ye ha’ really left the guid cause and turned prelate !”—“ Janet, (said the Bishop,) I have got new light upon these things.”— « So I see, Sir, (replied Janet,) for when ye was at Perth ye had but a’e candle, and now ye’'ve got twa before ye; that’s a’ your new light.” NAPIER OF MERCHISTON. 199 The name of Bacon suggests a view of this monument of Napier’s genius, which shows not only how important it is to his own biography, but how ho- nourable to the literary character of Scotland. In the midst of his scientific pursuits, and when his soul was imbued with the mysterious stores of Num- bers, our philosopher brought his theological work to light. It is a mis- take, as we shall afterwards see, to suppose that mystical theology was the study upon which the years of his manhood were “ wasted ;” and that only in the decline of life did he redeem the time with science and Logarithms. The true statement of his occupations is, that he at once assailed the strong- holds in which human knowledge was confined, at two separate points where the barriers were most formidable. FraNcis Bacon, Napier’s immortal con- temporary, and just ten years younger, was about the same time reviewing those strongholds with a glance so comprehensive, that nothing could escape its penetration. “ He surpassed,” says his elegant eulogist, “ all his predeces- sors in his knowledge of the laws, the resources, and the limits of the human understanding. The sanguine expectations with which he looked forward to the future were founded solely on his confidence in the untried capacities of the mind; and on a conviction of the possibility of invigorating and guiding by means of logical rules, those faculties which, in all our researches after truth, are the organs and instruments to be employed.”* In reviewing eccle- siastical history, Bacon distinguishes the history of prophecy. “ It forms,” says he, “ the second part of ecclesiastical history, and consists of two relatives, the prophecy and the fulfilment. Hence it ought to be founded on this principle, that every scriptural prophecy be compared with the event, and this through all ages, not only in confirmation of the faith, but in order to establish a certain discipline and skill for the interpretation of those prophecies whose accomplishment are yet tocome. ‘This department I mark as deficient, yet it is of a nature to be treated with great learning, sobriety, and reverence, or not at all.”+ In reviewing the department of mathematics, the same mas- ter mind observes of the most recondite branch of the abstract science, “ in arithmetic there is still wanting a sufficient variety of short and commodious * Dugald Stewart's Dissertation. + De Augmentis Scientiarum, lib. ii. c. xi. Vol. vii. p- 141. edit. 1819. Ad instituendam disciplinam quandam et peritiam in interpretatione prophetiarum, que adhuc restant complende.” —‘ Hoc opus desiderari statuo, verum tale est, ut magna cum sapientia sobrietate et reverentia tractandum sit, aut omnino dimittendum.” 200 THE LIFE OF methods of calculation, especially with regard to progressions, whose use in physics is very considerable.” ** A few years before Bacon had promulgated these observations, the retired and contemplative Scotch philosopher had en- deavoured to supply from the resources of his single mind both these deficien- cies. With a mental eye of equal penetration, and only not so excursive because a higher intellectual power impelled him to conquer where it dwelt,—he saw how much was wanting, and instantly set himself to supply what he could. While he toiled to institute “ disciplinam quamdam et peritiam in in- terpretatione prophetiarum,” he was continually extracting from the infi- nite play of numbers the most hidden and precious secrets of logistic. If the writings of Mede, Sir Isaac Newton, and Bishop Newton, have filled the de- partment of prophecy, so that Bacon could no longer pronounce it deficient,— even before he spoke, Napier had founded that very school by a work which may compete with their most elaborate productions. If the Virgule, the Scacchia, the Lamne, and the Logarithms, can be called such variety of com- pendious methods of calculation as Bacon desiderated, the glory is all due to Napier; and even before the “ the prophet of the arts,” had spoken, the des- tiny of NUMBERS was fulfilled by a mind mightier than his. + To have founded a school of mysticism would be little merit in a philoso- pher. Had Napier only (though with success) attempted to demonstrate that the Pope was Antichrist, and had calculated to a day the final judgment, he would have been, after all, no great benefactor of his race.

NAPIER OF MERCHISTON. 201 losophy to bear simply but systematically upon scientific theology, and by his writings to demonstrate, that the humble heart of a perfect Christian, and the profound head of a master in science, might be combined to illustrate the Scriptures. Napier, too, even for the most visionary portions of his work, finds an excuse in his times which cannot apply to modern writers. Whe- ther the Pope be Antichrist was then a great political and constitutional question upon which revolutions’ were pending; and although he treated it not as a political partisan, but with the calm and sincere conviction of a pious Christian, still the cause of freedom with which it was immediately mixed up, and the patriotic interests it involved, entirely remove his treatise on the subject from the class of useless and fanciful speculations, which the sub- ject is too apt to engender. In the present state of the world it creates no sensation to hear M. Biot announce, that it is impossible for him to believe the eleventh horn of Daniel to be the Church of Rome; but the times were very different when Napier wrote.* To this we must add, that when such * See M. Biot’s review of Brewster’s Life of Newton.—Journal des Savans, 1833, p. 339. Sir David says, ‘“‘ The Newtonian interpretation of the prophecies, and especially that part which M. Biot characterizes as unhappily stamped with the spirit of prejudice, has been adopted by men of the soundest and most unprejudiced minds.” But it is a mistake to talk of the Newtonian interpretation in this matter. Napier (pp. 46, 47, 48, 49, 50, 51, 352, 353, 354, &c.) has up- wards of nine quarto pages of condensed proofs, to demonstrate “ that the little horn in Daniel, chap. vii. doth signify the Roman Antichrist and not Antiochus properly as some suppose.”— P. 352, edit. 1611. The interpretation ought to be referred to Napier, and not to Newton. If it be true, he is entitled to the merit,—if it be false, his fame can better afford the failure, when we compare the times and circumstances under which he wrote with those of Sir Isaac Newton. It was from the years in which he was a commissioner to the General Assembly of the Church that Napier took his signs of the times; and we must sympathize with him even in his visions, to which Biot himself would not apply the epithet cliberal. No one had as yet commented on the Apocalypse systematically and historically. He wrote in the marvellous year, when the Church of Scotland was threatened from abroad, and betrayed at home,—when his own father- in-law (one in the court of the king) was a leader in the Popish plot. The signs he quotes are all immediately connected with the struggle betwixt the two religions. “ In the 88, 89, and 90 yeares of God (says he,)God hath, by the tempest of his winds, miraculously destroied the hudge and monstruous Antichristian flote, that came from Spaine against the professours of God in this poore iland: Againe, God hath stirred up one of the chiefe murtherers of the saints of God in Paris eyen the late King of France, to murther the Duke of Guize, and the Cardinall, his brother, speciall devisers of that cruell massacre. Then further, that mighty God hath stirred up a des- perat Papisticall frier to change lives with that bloody king ; so that by the sword, and mutuall blood-shed of Papists among themselves, the right of the crown of France is now fallen into the Cec 202 THE LIFE OF Protestants as Calvin and Joseph Scaliger openly avowed their impressions, that the whole Revelation of St John was an inexplicable mystery, of which the very writer was a problem, it is greatly to the honour of Scotland, that from the bosom of so rude a country a commentary should have come, worthy of the first scholar of the age, and capable, as we shall show, of instructing even our own enlightened times. When Napier commenced his labours, the modes of investigating and pro- mulgating the Scriptures, though beginning to be animated with a more ra- tional spirit, were yet very faulty. Every country that aspired to be free was now bursting the fetters of the Catholic faith ; but there were very few men, even among the learned, capable of teaching theology. As the century, at the close of which he appeared as an author, advanced, the sacred science reaped the benefit of the restoration of letters, in the substitution of biblical cri- ticism founded upon an examination of the sacred writings, in place of the pon- derous tomes and barbarous terms of the Positivi and Sententiarii, the divines of a false and unintelligible philosophy. Yet prior to Napier’s time not a single work can be pointed to, of the nature and extent of his, which like that is both profound and clear,—of varied erudition, yet simple in its doctrines, and systematic in the arrangement,—at once argumentative, succinct, and rational. Under these circumstances, the world was fortunate to obtain so beautiful an example of Scriptural investigation. He wrote amid a hurricane of contend- ing religions. He produced a work most effective in its disclosure of Anti- christ, but so replete with Christian charity, that its last sentence implores Antichrist to repent and be saved; containing matter for the reflection of sages; yet so clear and simple in its method, that a child might understand ; not, indeed, entirely free from the fallacies and mysticism that must ever at- tend a minute commentary on the subject, but chargeable with neither the weakness nor wildness of our own enlightened century, and treated with pre- cisely that “ sapientia sobrietas et reverentia” which Lord Bacon inculcated. One observation occurs forcibly upon a perusal of it, and. that is, its vast superiority in point of style, not merely to his contemporaries, but to hands of the King of Navar, who, pretending himselfe to have bene a Protestant, the church of true Protestants under him hath thereby had rest hitherto. And with these miraculous accidents hath this jubilee begun, hoping in God, before the end thereof, to heare that whole papistical city and kingdome of Rome utterly ruined: For these premises were as unlikely before those three yeares.” —Plain Discovery, p. 228. NAPIER OF MERCHISTON. 203 the popular and talented apocalyptic writers in Scotland of the present day. When the eye is relieved by the slight alteration which the anti- quated orthography requires, we find ourselves led into his alarming sub- ject by sentiments so rational, conveyed in sentences so distinct and un- affected, that our alarm begins to wear off soon after the title-page is passed. He commences in his introductory address by anticipating what in his time was the dictum of a tyrannical priesthood, and in ours is the pious pro- position of the weak minded,—namely, that every application of human rea- son to investigate the Christian scheme is forbidden. “ Although,” says he, “‘ the nature of the truth be of such force and efficacy, that after it is heard by the spiritual man, it is immediately believed, credited, and embraced ; yet the natural man is so infirm and weak, that his belief must be supplied by na- tural reasons and evident arguments. Wherefore many learned and godly men of the primitive church have gathered out divers pithy and forcible, natural and philosophical arguments to prove and confirm the Christian faith thereby. As in the Ist Corin. xv. 36, Paul, the learned and godly teacher of the Gentiles, persuading them to confess the resurrection of the dead, induceth a marvellous pithy and familiar argument, by a natural comparison of seed sown in the ground, that first must die and be corrupt in the earth, and then doth it quick- en up and rise again after another form than it was sown into. And likewise, other learned doctors of the primitive church, writing to the Ethnicks, (who stirred at the Virgin’s conception, and at Christ’s divinity,) reasoneth with them on this manner, saying, ‘ your Gods, as ye believe,’ have conversed with many women among you, and have begotten many children who have wrought no miracles; and how can ye, that so believe, deny us that our great God hath begotten one Son, in whom divinity and humanity are conjoined ; seeing your eyes and forefathers have seen so many and divine miracles wrought by him and in his name. And so most wisely used they these Gentiles’ own opinions and arguments against themselves ; which moved the malicious apostate Julian the Emperor to discharge from Christians the schools and learning of philo- sophy, yielding the reason, because saith he, propris pennis perimur.” This is the preamble of one who saw far before him, and deeply into his sub- ject; and the quiet, rational, historical tone of this fine old Scottish baron will be best appreciated by glancing for a moment to the most popular work on the same subject of the present day. Keith thus commences his Signs of 204 THE LIFE OF the Times :* “ Never, perhaps, in the history of man, were the times more ominous, or pregnant with greater events than the present. The signs of them are in many respects before the eyes of men, and need not to be told.” “ It is not a single cloud surcharged with electricity, on the rending of which a mo- mentary flash might appear, and the thunderbolt shiver a pine, and scathe a few lowly shrubs that is now rising into view; but the whole atmosphere is lowering, a gathering storm is accumulating fearfully in every region,—the lightning is already seen gleaming,” &c. &c. “ A citizen king, the choice of the people, and not a military usurper, sits on the throne of the Capets; and, as if the signal had gone throughout the world quick as lightning,” &c. “ from the banks of the Don to the Tagus,” &c. “ from the new states of South Ame- rica to the hitherto unchangeable China, skirting Africa and traversing Asia, to the extremity of the globe on the frozen North, there are signs of change in every country under Heaven,” &c. But no sooner is his first storm past, than the same author utters a sentiment highly complimentary to the more old fashioned style of our philosopher. “ It is not by a light issuing from the earth, nor by the meteor gleam of high imaginations, that a page of future his- tory can be read, or the dark recesses of futurity be disclosed.” This characteristic difference betwixt Napier and the moderns of the nine- teenth century prevails throughout the whole of their respective expositions. + * « Sions of the Times,” &c. by the Rev. Alex. Keith, &c. 2d edit. Edinburgh, 1832. See Introduction, &c. + See also “ A Dissertation on the Seals and Trumpets of the Apocalypse, and the prophetical period of 1260 years, by William Cunninghame, Esq. of Lainshaw, in the county of Ayr, 3d edit. Corrected and Enlarged.”—“ The result,” says the author, “ of thirty years’ meditations on this won- derful book.” But cui bono? To have excused the work it ought to have been more learned, more practical, more scriptural, more clear, and more original than Napier’s ; and these are precisely the advantages possessed by the old philosopher over the modern enthusiast. Yet it would appear, that in_ his thirty years’ meditation he had never read Napier. He says, “ to those who are conversant with the writings of the older commentators on the Apocalypse, it will be evident that I have carefully consulted their works,” &c. p. 28. He lays great stress upon the proposition, that “ the whole se- ries of the first siz seals relates to the church, with the exception of the political earthquake of the sixth,” p. 26, and not that the first applies to the church and the rest to the empire; and he adds, « Archdeacon Woodhouse, in his learned work on the Apocalypse, seems to he the first writer who has adopted” the view in the above proposition; “ till I saw his work I rested in the commonly received interpretation of the above seals.” Now, one of Napier’s divisions of the Apocalypse is into secular and ecclesiastical history. To the seals he refers the history of the church,—l1st Seal, NAPIER OF MERCHISTON. 205 A man of sound and sober judgment may read the Plain Discovery, and, without being satisfied of the accuracy of all its interpretations, close the volume a wiser and a better man than when he opened it. In the perusal his mind is suffered . to repose upon the sacred volume itself; and, without being either warpt or ir- ritated by the fancies of the ancient commentator, he may gather many a bright light and consolatory reflection from the practical wisdom and pure Christianity of which the staple of his work consists. With all his simplicity, Napier is singularly close and critical in his commen- tary. For instance, Bishop Newton, in commenting upon the first chapter of the Apocalypse, says, “ In the first vision Jesus Christ, or his angel, speaking in his name and acting in his person, appears,” &c. Napier sifts this material point. “ Some,” says he, “ may think this not to be Christ, but an angel bearing the type and figure of Christ, whom Christ had deputed;” and then, that the glory of God may not be given to angels, he enters into a close and beautiful argument to prove that quast filius hominis, and similis filio hominis, are meant not of a representation of Christ by another, but of Christ actually in the Godhead, though made visible to the prophet in the semelitude of his flesh ; “ not in his humanity, as the Son of Man, but in the likeness of the Son of Man.”t He then anticipates and exposes a sophism in the following character- istic manner: “ Here may some induce a sophism, saying, He who was dead and revived eternally, appeared to John. But Christ in his humanity died, and revived again eternally: therefore, Christ in his humanity appeared unto John. Christ opens and preaches the Gospel,—St Matthew. 2d Seal, Persecution of the church,—St Mark. 3d Seal, Increase of the Gospel,— St Luke. 4th Seal, Heresies in the church,—S¢ John. 5th Seal, Martyrs in thechurch under Nero. 6th Seal, partly ecclesiastical and partly secular; being the persecution of the church, and the revolting of the nations. So much for Archdeacon Wood- house’s originality. Again; ‘“ Interpreters,” says Mr Cunninghame, “ have generally supposed that the rider on the white horse is our Lord himself.” He dissents and again quotes Archdeacon Woodhouse, who says, “ the progress of the white horse seems to be rather that of the Christian religion,’ &c. But Napier explained all this centuries prior to Cunninghame or the Deacon before him. He interprets it, “the pure and holy teachers and apostles,” p. 140. Keith takes his signs from “ Annual Register,”—“ Capt. Alexander's Travels,’—“ Spain, by H. D. Inglis,’ —“ Sir Walter Scott's Napoleon,”—Edinburgh Almanack,”—“ Victims of Don Miguel's cruelty, Courter, July 13, 1831.” But this author lost a sign; for Count Cape St Vincent had not then taken Don Miguel’s fleet. In Cunninghame, Napier appears as if carica- tured ; in Keith, as if travestied. + P. 103. 206 THE LIFE OF For opening the deceit of this caption, the subject of the assumption is Christ alone: His atiributum is to die in His humanity, and to revive again eternally ; and therefore neither this His humanity, nor any part of this attributum, ought to be repeated in the conclusion, but only the subjectum Christ, with the at- tributum propositionis after this form : He who was dead and liveth eternally appeared unto John; but Christ died in His humanity, and revived again eter- nally : therefore Christ appeared unto John. And to the effect that the vul- gar capacities may understand these frauds, this is, as one would say in a fa- miliar example, he who carried this book to you wrote the same; but on horseback I carried this book to you, therefore on horseback I wrote this book. Whereas the right argument should be this wise disposed: he who carried this book to you wrote the same; but I carried this book to you on horseback ; or rather, simply, but I carried this book to you; therefore I wrote this book. Praying, therefore, the simple to beware of these and the like so- phisms, J thought good in this due place, to yield this one by way of example.” * Both Napier and Kepler took their illustration of the Trinity from science. The former notices “the marvellous harmony and accord in all points betwixt God and His holy Jerusalem.” “ God is one; so here by one only spiritual Jerusalem He representeth His church. There be three equal persons of the Deity; Father, Son, and Holy Ghost. So be there here of this Jerusalem three equal dimensions of longitude, latitude, and altitude. None of the three persons of the Deity is separable from other ; so none of these three dimensions of a city, or of any solid body, can be separable one from another, for then should it become a superfice and no solid body. The three persons of the Deity and their functions cannot be confounded ; so are not these three dimensions confounded, for the length is not the breadth, nor the breadth the height.”+ Kepler, in his Har- monices Mundt, took the spherical world as an image of the Trinity. He supposed the Father the centre, the Son the surface, and the Holy Ghost all that is betwixt the centre and the surface; and thus inseparable without be- ing confounded. Kepler’s Christianity, however, was mixed up with the wild- est flights of an exuberant imagination. Napier’s presents that chastened so- briety throughout, which renders many of his notes and illustrations plain and practical discourses. How refreshing is it to turn from some noisy tirade in our own times against good works, to a reconcilement of the doctrines so * P. 106. + P. 313. NAPIER OF MERCHISTON. 207 simple and satisfactory as this: “ By works here are we judged and justified, and not by faith only; as also James ii. 24, testifieth ; meaning thereby, that of lively faith, and of the good works that follow thereupon, man is justified ; and not of that dead faith that is by itself alone without any good works; otherwise were the words of Paul (Rom. 3. 28,) expressly contrary to this text and to James; for saith Paul, ‘ we are justified by faith without the works of the law; that is to say, not without good works whatsoever; but meaning that we are justified by lively faith, with such small good works as our weak nature will suffer that faith to produce, although it be without the precise works that the law requireth. And for confirmation of this interpretation, and union of these texts, ye shall find both James and Paul agree in divers places that faith without works is a dead faith, and serveth nothing to justifi- cation. And again they agree both, that all works, how good soever they seem, that proceed not from faith are evil. And so it is no difference to say with Saint Paul, we are justified by fruitful faith, or faith that produceth good works, although not the works that the law requireth; or to say with James, and here with Saint John, we are justified by faithful works; seeing a work- ing faith and faithful works are inseparable, and none can have the one with- out the other. So for conclusion, these works by the which here we are judg- ed, are to be esteemed good or evil, not in themselves or in so far as they sa- tisfy the law, (for so were all works evil and imperfect,) but in so far as they have or want faith adjoined with them, they are accounted good or evil only.”* As some of our modern theologians might cull from him a correction of their mysticism, so might others of their credulity. A popular historian of the Church of Christ solemnly records, as a Christian miracle, the fable that “ Constantine marching from France into Italy against Maxentius, on an expedition which was likely either to exalt or ruin him, was oppressed with anxiety. Some god he thought needful to protect him. The God of the Christians he was most inclined to respect.”——“ He prayed, he implored, with much vehemence and importunity, and God left him not unanswered. While he was marching with his forces in the afternoon, the trophy of the cross appeared very luminous in the heavens, higher than the sun, with this inscription, ‘ Conquer by this.’ He and his soldiers were astonished at the sight. But he continued pondering on the event till night. And Christ appeared to him when asleep, with the same sign of the cross, and directed him to make use of the symbol as his military Pp 296). 208 THE LIFE OF ensign.” * But Napier, with much better reason, takes this as about the com- mencement of the abused mark of the cross, “ which,” says he, ‘‘ was now in- duced among the Christians by the fabulous alleagance of two feigned mira- cles; the one, that Queen Helen the mother of Constantine, admonished by an heavenly vision, passed, and did find that very real cross whereon our Lord suffered ; the other, that Constantine her son, fighting against Maxentius, saw appear in the air the figure of a cross, with these words, zm hoc signo vinces, by this mark thou shalt overcome, with which mark and inscription the Por- tugal ducat and some other coins of late are imprinted.” + He interprets the text (Rev. xx. 6,) regarding the reign of Christ for a thousand years, to mean eternity, and thus treats the millenary doctrine : “ By this text, literally and definitely taken, resulted the great error of Cerin- thus, and his sects of Chilasts or Millenaries, who thought our reign with Christ to be on earth, and temporal, for a thousand years, and we then again to die and ly dead another thousand years, and so about by vicissitudes, as did of old the Platonicks, and of new in a manner the Originists. Further, some also, by the mistaking of this text, suspected the authority of this whole Revelation ; but to the true Christian conceiver thereof, both is the authority of this book confirmed, and the heresy of the miilenaries refelled.” The following may be taken as an example of his philological learning, of which there are many indications: “The vulgar text saith here, (Rev. x. 7,) quum ceperit tube canere consummabitur mysterium magnum ; that is, ‘When he begins to blow the trumpet ;’ but the original Greek may ra- ther import, ‘ After he shall blow the trumpet ;’ for the word éra» may more justly be taken for after than for immediately or incontinently when, &c. as is to be seen in Mark iv. 32, where ora» is taken for a long time after, and not instantly ; for there it is not meaned that the seed which is sown doth in- stantly rise up; and John viii. 28, by the word éray meaned not that instant- ly after the crucifying of Christ they should know him truly, but rather after a certain progress of time from his passion. We therefore here justly dis- assent from the vulgar translation,” &c. And thus he scatters classical allu- sions and quotations throughout his commentaries. “ This Susy is the word Thyia, which Theophrastus reporteth to be a long-lasting and incorruptible timber ; thereof mentioneth Pliny, Lib. xiii. c. xvi. ; and with this timber tem: * Milner’s History of the Church of Christ, Vol. ii. p. 41. Edit. 1827. + Napier says, “ Constantine was illuded by a cross shadow in the clouds.” —pp. 75, 89. 3 NAPIER OF MERCHISTON. 209 ples in old times were decored and, replenished.” Again, “ Aretas reporteth that the ancients were accustomed to give a certain white stone to him that did get the victory in their plays and games. Moreover, among the ancients they that cleansed or absolved an accused person did cast in a white stone, and they that filed or convicted him did cast in a black stone, as Ovid testifieth, Lib. xv. Metamorph. in these words, “ Mos erat antiquis, niveis atrisque lapillis, > 99 His damnare reos, < illis absolvere culpa. Nor must we omit a notice that may interest the antiquaries. When illus- trating the names of blasphemy upon the seven heads of the beast, our philo- sopher refers to the superscriptions and titles dedicatory of the Roman mo- numents; “as,” says he, “ Diis manibus, Fortuna, Plutoni, Veneri, Priapo ; and even at Musselburgh, among ourselves in Scotland, a foundation of a Ro- man monument lately found, now utterly demolished, bearing this inscrip- tion dedicatory, Apollint Granno Quintus Lucius Sabinianus Proconsul, Aug.” Sometimes he illustrates a proposition as Lord Stair might have done. “ Our lawyers, in the account of the six days that go betwixt every citation and summons of the letters of four forms, neither account the first day of the summons, neither the next day, nor any day upon which they do summons; but, leaving out the extremes, they reckon only the six middle whole days, upon which no citation or summons falleth. As, for example, if the first summons be execute upon Tuesday, it is not lawful to execute the next summons before the next Tuesday, and this they call a summons of six days.” (We wish that my Lord Stair had always been as distinct.) At other times, as if, like Kep- ler, he could have written a treatise on music. ‘“* Among the musicians, the eighth voice, or octave above de-sol-re, is called de-la-sol-re, and the octave above de-la-sol-re is called de-la-sol ; yet, from de-sol-re to de-la-sol, there are not twice eight, or sixteen voices or harmonical notes, but fourteen alanerlie ; and yet is that space called two octaves.” These are but a few, and, perhaps, not the best selected examples of the practical nature of his theological works, upon a subject, and in times, which afforded every temptation to run into barbarous mysticism and controversial jargon. Such is the manner which our philosopher adopted to instruct the uninformed of his own country ; the sobriefas et sapientia with which he handled the dangerous subject of prophecy. Dd 210 | THE LIFE OF At the end of his treatise are added, “certaine oracles of Sibylla,” the au- thenticity of which Napier doubted, but inserted in this place rather than omit them entirely, as they were ancient, generally believed, and coincided with the Scriptural prophecies. They are chiefly to be noticed, however, as affording a good specimen of his powers of versification, and the extent to which he car- ried his flirtation with the muses. He mentions that he gives these oracles from Castalio’s Latin translation, “ faithfully Englished this way.” Of these we may select a few specimens. O cursed and unhappy Italy, Unmeind or mourned for, barren shalt thou be. To ground as green as wilderness unwrought, To woodes wild, and bushes beis thou brought. Far shalt thou flit into an uncouth land, Thy riches shall be reft out of thine hand. In thy wall-steds shall wolves and tods convene. Waste shalt thou be, as thou hadst never been. Where then shall be thy oracles divine ? What golden Gods shall keep or save thee syne ? What God, I say, of copper or of stone. Where then shall be the consultation Of thy senate? What helps thy noble race Of Saturn, Jove or Rhea, in this case, Whose senseless souls and idols thou before Religiously didst worship and adore. The fathers old, and babes shall mourn for thee, Beholding then thy dolorous destiny. On Tiber banks lamenting sore thy case, Sad shall they sit with many loud alace. Lament shall you, and mourn, laying aside Thy purple weed, imperial robes of pride, And into sackcloth sitting sorrowful, Repeat shalt thou thy plaintis pitiful. O royal Rome, thou bragging prince but peer, Of Latin land the only daughter dear ; Thy pride, but pomp, ruined shall remain, Thou, once trode down, shall never rise again ; For gone shall be the glore of that armie, That bears the eagles in their enseignie. “ Then ends the world, then comes the latter light, NAPIER OF MERCHISTON. 211 Then God shall come to judge his folk aright. But first shall fall on Rome, but resistance, Of God, his wrath, the wofull vengeance. A wofull life, a bloudie time shall be. Oh! people rude, oh land of crueltie, Thou little lookest, nor doth regard aright, How poor and bare thou first came in the light, _ That to the like again you should return, And last, before a dreadful judge should murne. We have known an Oxford prize-poem worse than this. There is one view arising from the whole of this chapter of our philosopher’s history which must not be omitted. Those who are incapable of appreciating the power and originality of mind necessary to have invented the Logarithms, but who, at the same time, can just understand that Napier did something for science, are apt to regard him in the same light that the historian Pinkerton did,—** only an useful abbreviator of a particular branch of the mathematics.” In this view of his capacities, he would rank with that inferior class of scienti- fic men, who possess power sufficient to act upon principles already discovered, but have not within themselves the intellectual resources for establishing ori- ginal principles. How mistaken this view of Napier’s genius is, will be best seen when we come to the history of his mathematical life. But it is not unim- portant to observe, and it will stand as an excuse for our having dwelt so long upon the subject, that from the review of his theological character we may arrive at the same conclusion, that, as a man of science, he must have belonged to the very highest class, the class of Newton, and could not have been a mere mathema- tician. Ina recent philosophical production, the question has been admirably considered, how far the study of mathematics is unfavourable to religious views; or, to put the proposition more fully in the words of the author, how far “ deductive habits, or the impression produced on men’s minds by tracing the consequences of ascertained laws,” are unfavourable to “ a belief in a Divine Author of the universe, by whom its laws were ordained and established.” * Now, the value of this writer’s solution of the question, is the establish- ing a distinction betwixt those capable of original discovery, and those * Astronomy and General Physics considered with reference to Natural Theology, by the Rev. William Whewell, M. A. Fellow and Tutor of Trinity College, Cambridge. London, 1833,— P. 302, et infra. 212 THE LIFE OF only occupied with derivative speculations. If there be, says his argument, a tendency in men of science to refer every thing to mechanical causes, and to exclude from their view all reference to an intelligent First Cause and governor, it is not owing to “ the mathematical habits of the mind, but the deficiency of the habit of apprehending truth of other kinds,—not a clear insight into the mathematical consequences of principles, but a want of a clear view of the nature and foundation of principles,—not the talent for generalizing geometrical or mechanical relations, but the tendency to erect such relations into ultimatetruths and efficient causes.” How well does this illustrate the intellectual calibre of the man who wrote the Plain Discovery, and invented the Logarithms; and how bright an example does Napier afford, that a falling off from religion must ar- gue a defective rather than a perfect scientific constitution ? How well does this prove that it would be great neglect in his biographer not to bring prominently into view the whole history of his theological studies ? For it is the combined view of the two great characteristics of his mind, its RELI- GION and its SCIENCE, that will best prove him to have been, not “ the ma- thematical philosopher dwelling in his own bright and pleasant land of deduc- tive reasoning, till he turns with disgust from all the speculations in which his practical faculties, his moral sense, his capacity of religious hope and be- lief, are to be called into action ;’—but one of “ those mathematicians whose minds have been less partially exercised,—the great discoverers of the truths which others apply,—the philosophers who have looked upwards as well as downwards,—to the unknown as well as to the known,—to ulterior as well as proximate principles,—and who have perpetually looked forward beyond mere material laws and causes, to a First Cause of the moral and material world.” * * Astronomy and General Physics considered with reference to Natural Theology, by the Rey.

HavineG bestowed a chapter upon our philosopher’s theological works, and thereby, it is hoped, at least afforded the means of forming a juster estimate of his character in that respect ; we would have wished to relieve the dulness of our imperfect review, by introducing the reader more particularly to Napier himself,—by making him as well acquainted with the Baron of Merchiston as he is with the Baron of Bradwardine,—and inducing him to spend, like Henry Briggs, * one whole month with him in his war and weather-beaten tower. We are certain that a month of real life at Merchiston, enjoyed through the safe medium of a minute and graphic account, would satisfy the keenest appetite for romance, without offending the lovers of truth and his- tory. From what can be discovered, it is obvious that all the ingredients es- sential to the most fascinating historical novel actually occurred in the career of the Inventor of Logarithms. Independently of his sound and _ practical views of the Christian scheme, and of his substantial triumphs in mathema- tics, he moved amid a halo of the romance of religion, the romance of science, and the romance of history. He persuaded others no less than himself, that he had ascertained about the period of the end of all things earthly ; and he stood among the Protestants of Europe as the being who, by the intensity of his faith, and the depth of his speculations, had been enabled to read the world its destiny, and from encountering whom the boldest of the Catholic champions shrunk back. He had gazed, too, upon the stars with more than mortal] aspirations ; and while he was silently determining, that, through his means, their eternal paths should be subjected to a more certain and rigorous * « Ubi humanissime ab eo acceptus, hest per integrum mensem,” says Briggs of his visit to Merchiston. 214 THE LIFE OF scrutiny, he had caught a corner, at least, of the mantle of Cardan, and loved to trifle with those mysterious indices of futurity. All this, in addition to the romantic historical relations already traced, would give us something be- yond “ the cold, dry, hard outlines which history delineates ;”* and did we but possess good store of the connecting links of daily incident and domestic intercourse, there would be in this instance little need “ to fill up and round the sketch with the colouring of a warm and vivid imagination, which gives light and life to the actors and speakers in the drama of past ages.” | With- out the pen of Scott, but with some of those every-day facts which must have connected the prominent features of our philosopher’s life, one month in Mer- chiston, at any time from the epoch of the Douglas wars to the commencement of the seventeenth century, would be fairly worth two,—even at Tully-Veolan. There is this remarkable circumstance in his history, that while he pos- sessed the respect and confidence of the most able and Christian pastors of the Reformed Church, and while he was looked up to and consulted by the Ge- neral Assembly, of which he was for years a member, he was at the same time regarded, and not merely by the vulgar, as one who possessed certain powers of darkness, the very character of which was in those days dangerous to the possessor. ‘Traditions to this effect might be met with in the cottages and nurseries in and about the metropolis of Scotland not many years ago; and the marvels attributed to our philosopher, with the aid of a jet-black cock supposed to be a familiar spirit bound to him in that shape, have, within the memory of the present generation, been narrated by the old, and listened to by the young. We cannot help suspecting that the legend of the black cock is in some way connected with the hereditary office of king’s poulterer (Pultrie Regis,) for many generations in the family of Merchiston, and which descend- ed to John Napier. This office is repeatedly mentioned in the family charters as appertaining to the “ pultre landis,” hard by the village of Dene, in the shire of Linlithgow. ‘The duties were to be performed by the possessor or his deputies ; and the king was entitled to demand the yearly homage of a present of poultry from the feudal holder. It is not improbable that our phi- losopher made a pet of some jetty chanticleer, which he cherished as the badge of his office, and as worthy of being presented to the king, si petatur.t If so, * Waverley. + Ibid. + The Society for the Diffusion of Useful Knowledge has Mephostophilized our philosopher. «« It was believed, it seems, that he was attended by a familiar spirit in the shape of a large black dog.’ —Pursuit of Knowledge under Difficulties.

A story was once abroad of this animal, which has since reappeared in some popular drama or nursery tale. It is said that Napier adopted the policy of Mahomet to control his own domestics, and impressed them with a belief that he and chanticleer together could detect them in their most secret doings. Having missed some property, and suspecting his servants, he ordered them one by one into a dark room, where his favourite was confined, and declared that the cock would crow when the guilty one stroked his back, as each was required to do. The cock remained silent during all the ceremony ; but the hands of one of the servants were found to be entirely free from the soot with which the feathers of the mysterious bird had been anointed. The story of his be- witching the pigeons is yet remembered about the neighbourhood of Merchis- ton. He had been annoyed by the flocks that ate up his grain, and threaten- ed to pond them. “ Do so, if you can catch them,” said probably his “ nich- bour, the Lard of Roslin ;” and next morning the fields about “Merchiston were alive with reeling pigeons, who were easily made captives, from the in- toxicating effect of a dose of saturated pease.* There are other traditions of the Laird of Merchiston which savour more of supernatural means ; but lest the reader suspect us of taking liberties with his credulity, we shal) content ourselves with referring to similar reminiscences, met with about the place of Gartness, part of the Napier property in the Menteith, in the words of the clergyman who collected them for the Statistical Account of Scotland. * Adjoining the mill of Gartness are the remains of an old house in which John Napier of Merchiston, Inventor of Logarithms, resided a great part of his time, (for some years,) when he was making his calculations. It is reported that the noise of the cascade being constant, never gave him uneasiness ; but that the clack of the mill, which was only occasional, greatly disturbed his thoughts. He was therefore, when in deep study, sometimes under the neces- sity of desiring the miller to stop the mill, that the train of his ideas might not be interrupted. He used frequently to walk out in his night-gown and cap. This, with some things which to the vulgar appeared rather odd, fixed on him the character of a warlock. It was firmly believed, and currently re- ported, that he was in compact with the Devil; and that the time he spent in fait représenter dans une Médaille, ou étoient gravés ces mots, Tychonis Brahei delitium.”—His- toire des Philosophes Modernes, T. v. p. 59, 1766. Upon the seal of a letter written by one of Napier’s brothers, I find the symbol of a cock. * A field in front of Merchiston is pointed out as the scene of this exploit, and still called “ the Doo Park.” 216 THE LIFE OF | study was spent in learning the black art, and holding conversations with Old Nick.”* From this worthy clergyman’s narrative, we might be led to sup- pose, that our philosopher cooled himself of an evening by walking abroad in his night-gown and night-cap ; a freak more decent to be sure, yet even more ridiculous than the ecstacy of Archimedes, who rushed naked from the bath through the streets of Syracuse. But if the reader will turn to the etching which illustrates our Preface, he will there see the sober cowl and gown in which, we doubt not, our philosopher frequently appeared ; and he will exone- rate him from the charge of a more eccentric costume. He himself remarks, in his notes upon the first chapter of the Apocalypse, “long garments or gownes were of olde, and to this day, worne of doctors and senatours, to repre- sent gravitie and wisedome.” If, as the Reverend Mr Ure reports, John Napier really enjoyed in his own times the character of “ holding conversations with Old Nick,” it is a most re- markable fact in his history, that never for a moment did he fall into the slightest “ cummer” on that account. The period of the Popish conspiracy, to which we have brought down his memoirs, was particularly fertile in per- secutions for sorcery and witchcraft; and, when the cry was once raised against an individual, neither rank nor innocence were sufficient to afford pro- tection. ‘The name of Napier, too, had about this time come under that fatal imputation. David Moysie the notary (who was well acquainted with the Merchiston family during the life of the philosopher) records, that, in the year 1590, “ Barbara Neapper, and Euphane M‘Kallian, [a daughter of the Lord of Session of that name,] wemen of guid reputation afoir, wer teane as witches, + with sundrie utheris, baithe men and weemen. Sampsoun wes brunt, and died weill; the rest wes keepit.

Quhairupone the Erle of Bothuell being send for and ac- cusit, being ane great poynt of treasoune, wes committed to waird within the Castle of Edinburgh, and verie straitlie keepit.”. This accusation and harsh treatment drove Bothwell to the roving life of turbulence and treason, which for several years kept King James in constant and almost ludicrous terror ; until the Earl, who long contrived to make his hand save his head, was at last * Account of the Parish of Killearn, Stirlingshire, by the Rev.

I cannot discover the slightest connection betwixt Bar- bara Napier and the family of Merchiston ; but it is singular that John Na- pier may be traced into one very curious instance of dangerous proximity to this Earl of Bothwell, to whom the imputation of sorcery clung, like the mark of Cain, wherever he went. A very pleasant exercise of such powers was the discovery of hidden treasure, which, from the lawless and unsettled state of the country, (so strongly commented upon by Napier in his letter to the king,) was not un- frequently secreted by those who never returned to recover it. At the crisis of the battle of Glenlivet, when the Popish earls defeated Argyle, the public mind was deeply imbued with the imagination of effecting such precious discoveries by supernatural means. It appears that Argyle had along with him in the field of battle a noted sorceress, for the express purpose of bringing to light, by her incantations, the treasures hid under ground by the terrified in- habitants.* This was one of the arts for which Bothwell was famed ; a repu- tation he attempted to turn to profitable account in his exile. The traveller and poet, George Sandys, mentions, that when he was abroad in the year 1610, ** a certain Calabrian, hearing that I was an Englishman, came to me, and would needs persuade me that I had insight in magick, for that Earl Bothwell was my countryman, who lives at Naples, and is in those parts famous for suspected necromancy ;” and Sir Charles Cornwallis, in a letter to the Lords of the Privy-Council, dated from Valladolid 1605, after mentioning some of the banished nobleman’s scandalous freaks on the continent, adds, “ this moves the rest of his carriages to be looked into; and, by takeing upon him to tell fortunes and help men to goods purloyned, he hath incurred the suspicion of a sorcerer.” + Now it must be observed, that before the earl was driven out of Scotland, one of his sworn friends and most useful allies was that turbulent and irregular baron, Robert Logan of Restalrig. Hewas the head of an ancient and powerful family, long in possession of what amounted to a principali- ty of property about the town of Leith, but which was greatly dissipated in the hands of this unprincipled representative. Robert Logan, however, had made ? * There is preserved in the Advocates’ Library a Latin manuscript, being a contemporary cir- cumstantial account of the battle of Glenlivet or Belrinnes, where this fact is particularly men- tioned, “ Adde et illud quod insignem veneficam itineris comitem habuerint, eo consilio ut suppel- lectilem ab incolis metu reconditam, et thesauros abstrusos, incantationibus proderat,” &c. + Winwood’s Memorials of State Affairs. Ee 218 THE LIFE OF one acquisition of no small value to a person of his propensities and habits, and that was the fortress of Fastcastle, being one of the most impregnable places in the kingdom. Overhanging a sheer precipice of vast height washed by the German Ocean, it required very little skill in those times to render such a strong- hold as secure from mortal invasion as the depths of the ocean.* Logan did not constantly inhabit this wild and dreary fastness, but reserved it for des- perate emergencies, living occasionally in a more Christian-looking dwelling- place in the vicinity. According to a mass of evidence collected on the sub- ject, it was by this baron, in conjunction with the Earl of Gowrie, that the fearful conspiracy was hatched to carry off King James and seclude him from human aid and converse in the dungeons of Fastcastle. Here it was that Francis Earl of Bothwell was always sure of a safe retreat when hard pres- sed by the king’s troops or the officers of justice ; and here, too, his necromantic propensities must have met with the fullest encouragement, for no man was more constantly haunted with the hopes of recovering buried treasure than his host Robert Logan of Restalrig. The first scene in the Gowrie conspiracy opens with a reference to this natural craving for gold, satisfied by superna- tural or sinister means. “ The fyft day of August 1600, Mr Alexander Ruthven, brother to the Erle of Gowrie, come tymuslie to Falkland, quho did informe the kingis majestie that certane gold wes fund within the grund, in a plaice with the quhilk he wald on no wayis meddle unto sick tyme as his majestie did sie it, quairupon his majestie come to Perth to dyne with the said Erle,” {+ &c. and the organization of this hellish plot is traced to Lo- gan under his own hand. As we must immediately disclose our philo- sopher in most extraordinary juxtaposition with this desperado, we shall premise an extract from Logan’s original letters, preserved in the Re- gister House, which place his character and habits under the most pene- trating light. In one letter to the Earl of Gowrie, dated in July 1600, after impressing him with the necessity of profound secrecy, he adds, “ and than I dout nocht, bot with God’s grace we sall bring our matter till ane fine, quhillk sall bring contentment to us all that ever wissed for the revenge of the * « The fortress called Fastcastle overhangs the German Ocean, occupying almost the whole projecting cliff on which it stands; connected with the land by a very narrow path, and of such security that, manned with a score of desperate men, it must in those days have been impregnable, save by famine.”——Sir Walter Scott's Hist. of Scotland. + Moysie’s Memoirs.

They are printed and illustrated in Mr Pitcairn’s Collection of Criminal Trials, where the curious reader will find the character of Restalrig more fully displayed. It may be remarked, that his letters conclude with committing his correspondents in this nefarious matter “ to the protectioun of the Almychtie God,” or “ to Chrystis haly protectioun,” and yet he 220 THE LIFE OF About the commencement of the year 1594, the very time when he was shel- tering the Earl of Bothwell in his stronghold in defiance of king and council, and a few months after the date of John Napier’s letter to his majesty in re- ference to the Spanish plot, Restalrig, in great need no doubt of the sinews of war and wickedness, adopted two modes of acquiring wealth. He seems to have sent his servants to the king’s highway, with instructions to knock down and rob, and, if necessary, to murder the richest man they could meet; and he, at the same time, determined to apply even to higher authority than his guest the Earl of Bothwell, or, in legal phrase, to retain the best counsel in Scot- land, upon the necromantic question of treasure buried at Fastcastle. In the books of the High Court of Justiciary, it stands recorded, that, upon the 13th June 1594, Robert Logan of Restalrig is ordained to be denounced rebel, for not appearing before the king and council, to answer a charge at the instance of Robert Gray, burgess of Edinburgh ; “ makand mention, that, quairupoun the secund day of Aprile last, he being passing in peceable and quiet maner to Berwick, for doing of certane his lessum effearis and busynes, lippynning for na trouble nor injurie of ony personis, treuth it is, that Johnne, alias Jokkie Houldie, and Petir Craik, houshald servandis to Robert Logane of Restalrig, with three utheris, thair compliceis, umbesett his hie way and passage, besyde the Bowrod ; quha not onlie reft and spuilzeit fra him nyne hundredth and fiftie pundis money, quhilk he had upoun him, bot alsua, maist cruellie and barbarouslie invadit and persewit him of his lyffe, hurte and woundit him in the heid, and straik him with divers utheris bauch straikis upoun his body, to the grite danger and perill of his lyffe, to the said complenaris utter wrak,” &c. Logan failed to appear and present these robbers for whom he was respon- sible; and was outlawed accordingly. How he was engaged immediately after this sentence had passed against him, will be seen from the following contract, which IJ find among the Merchiston papers :— * Contract Merchiston and Restalrik. « At Edinbruch the day of Julij, yeir of God im v‘ foirscoir fourtein yeiris (1594. |—It is apointit, contractit, and agreit, betwix the personis ondirwret- tin; that is to say, Robert Logane of Restalrige on the ane pairt, and Jhone Neper, fear of Merchistoun, on the uther pairt, in maner, forme, and effect as gives as a reason for excluding Gowrie’s “ auld pedagog,” Mr William Rhind, from the plot, that he “ will dissuade us fra our purpose with ressounes of religion quhilk I can never abyd.” NAPIER OF MERCHISTON. 22) folowis :—To wit, forsamekle as ther is dywerss ald reportis motiffis and ap- pirancis, that thair suld be within the said Robertis dwellinge place of Fas- castell a soum of monie and poiss, heid and hurdit up secritlie, quilk as yit is on fund be ony man.

In that year one Sprot, a notary, was such an idiot as to drop a hint that he knew something of the matter, and even that he had stolen Logan’s letters from the old messenger “ Laird Bour.” This was sufficient to bring upon himself the extremity of torture, and the most ignominious death. His depositions were taken before the privy-council; the letters were produced, and identified with Logan’s hand-writing, comparatione literarum. Lo- 222 THE LIFE OF The existence of this singular contract has been hitherto only partially known through the medium of Mr Wood’s edition of Douglas’s Peerage, from a communication to that gentleman by the late Lord Napier; but the details of it have been nowhere published, and the matter remained wrapt in such mystery as might lead sceptical antiquaries to suppose that there was some misapprehension on the subject. Upon examining, however, the original do- cument, we discover a circumstance which adds greatly to its interest and antiquarian value. The entire contract, with the exception of Logan’s own signature, is carefully written by the hand of John Napier himself. There is no question of the fact; and it is even apparent, on comparing (as may be done in the fac-simile here given) the *‘ Jhone Neper” of the are with that which occurs in the body of the deed. Having displayed this page of his history, and picture of his times, to the public eye, it is necessary to meet two ideas very naturally arising from a hasty view of the transaction. It may appear to call in question both his moral conduct and his mental power. The first idea is easily dealt with. The circumstance of this casual intercourse with one of the darkest characters of his times, for the special purpose detailed in the contract, is totally innoxious against the author of the Plain Discovery,—the friend of Robert Pont,—the leading commissioner of the assembled church,—and he who only six months before wrote the letter of Christian admonition to King James, which has been quoted. All this, and the fact, that during an age of tyrannical superstition, gan’s mouldering bones were dug up, produced in court, tried, condemned and executed. Sprot was led to the scaffold for his pains, where he adhered to his extraordinary confession in the face of a vast and attentive multitude ; and, says Spotswood, gave the people a sign of his truth, “ by clapping his hands three several times after he was cast off by the executioner.” The letters, de- positions, &c. were all, by command of the king, engrossed in the records of the Parliament of Scotland ; and the original letters themselves have recently been discovered in the Register-House. They have been called forgeries ; but the weight of evidence in support of their authenticity seems irresistible. It is interesting to institute the comparatio literarum now, which Napier was too wise to allow to be made at the trial of Logan’s bones. This the reader may do by comparing the signa- ture of the contract with the fac-similes of the letters in Pitcairn’s Trials. The “ Restalrige” in both are certainly very similar; but this must be observed ; the dittay against Logan specially narrates, that the letters were subscribed “efter his accustomet maner, with this woird Restalrig ;” whereas the contract has his name in full. Napier’s cousin-german, the Bishop of Orkney’s eldest son, (first Lord Holyroodhouse, ) was one of the assessors on the trial of Sprot, attended him on the scaf- fold, and attested his dying confession. / eeataa Mos ‘g ry Ae eet at A a a sie ie ie ae poten i ipl sane 164 om fi Fe ee i oo rae eC LP EX: otha la JE as e Y HA. ne Logan “f voftabrar o oy as aa) & mip af gy 1 eM oF vies £3 Linc le a na ieee i eee eh bo ws y B sash netigs p Lie A 2 mone ‘oe se / Pr be eee jae Q, ape Wa © seact- Pao f° ib eC bs al mm a A eee, OF ok 4 : 7 ani bo Tae fe fi8 yp erry RSs ; a rE Sl ‘ | eee Bo ie any a li met rae (Be ne | ye -Ovb briny ay / Lee fas pr iar al ok ak BE obra atk if, tie v6 oT : eae ee pps DI aREE kod ; Lond boat as ee. me: ies 48 —s God bind be g saa mAh vom o-abwk yx far) Pag Bele ha (hb ‘ aut Beige be ie wb oe a def Mad Gallanes— / betrve vary On jn tl omy vane FE tips Leer Ws ba: poy & Cu, aie ss Aye. yf ge ps wid. al in fone fe ayy uthiy ag bt ° fi? land pid pea ee i fags He mah Ff Gy fow* i. nd lf an @ nb / and 4 I by Fe aa orl fo oe a Geund- : = CN iaaté Gainer f vn babs, epee v7) : .

The singularity of his holding conference with one who had just been proclaimed an outlaw, and whose lawless violence is alluded to and provided against by Napier himself, must be accounted for by the rude state of society, and the simplicity of our philosopher’s character. He took care to word the contract himself, however, and there is not an expression which indicates an idea beyond the most legitimate purpose ; but, under the shield of his own innocence, he ne- ver dreamt of contamination from his company ; was fond of the romance of science ; and not averse (nothing derogatory in his times) to the prospect of gold. We must admire, moreover, the undaunted courage of the man, who was willing to go alone with the robber to his cave, and only stipulated for a safe convoy back again to prevent his being robbed by Logan’s own domes- tics. ‘To pronounce the transaction mercenary would be to apply the fal- lacious test of modern notions to the dimly seen manners of antiquity. As the deed is still in existence, we must suppose that the terms of it had not been fulfilled; nor is it improbable that no faith had been kept by Robert Logan; but the idea is too picturesque to be entirely discarded, that the philosopher actually went to the dreary castle overhanging the German Ocean; that there, in his gown and cowl, he sat betwixt the wild Earl of Bothwell and the turbulent Restalrig, both armed to the teeth ; that he partook of their “ daynty cheir—fyne hattit kit with succar, comfeitis and wyn;” and that the necromantic nobleman and the lawless chief bowed before the pure but mighty mind, for whom the destiny was yet in store to become the universal benefactor of science and the arts. Whether he found the treasure, or got back to Merchiston “ on beand spulzeit of his said thrid pairt, or uther- ways hairmit in body or geir,” is another matter. But that the reader may be assured that John Napier immediately dropt the acquaintance, and fore- swore the society of Robert Logan, we shall lay before him the preamble of a lease among the philosopher’s papers. “ At Gartnes, the xilij day of Sep- tember, the yeir of God a thousand, five hundreth, fourscoir saxtein yeirs ; it is agreit betwix Johne Neper, fear of Merchistoune, and Robert Ne- per of Blackyairdis as cationer for him, on the ane pairt ; and Johne Cun- nynghame of Ross, principall,” &c. “on the uther pairt, as followis, to witt,— The said Johne Neper sall sett to the said Johne Cunynghame of Ross, and his subtennentis, labourers of the ground, allanerlie nocht of the surname of 224 THE LIFE OF Loganes, nor Cunynghames of the houss of Drumquhassell, all and haill the four pund landis of Blairour,” &c.; and further on in the same deed the condition is more positively repeated, that the lessee oblige himself that he *‘ nather directlie nor undirectlie, nor yitt be na maner of pactioun, private or publicke, sall suffer or permit ony persoune beirand the name of Logane, or Cunynghame of the houss of Drumquhassell, to enter the possessioun,”* &c. As a page in the intellectual history of mankind, the contract now before the reader affords matter for curious and interesting reflection. It is well known, that, at the period of its date, the chrysalis of the adept was still hang- ing upon the brilliant wings of science, and that superstition darkened the fountains of justice with innocent blood. Astronomy had not yet escaped from judicial astrology ; nor chemistry from alchemy ; nor mathematics from magic squares and mysterious powers of numbers ; nor (horresco referens ) the High Court of Justiciary from its belief in witchcraft. We are prepared in short, by the history of that age, by the lives of its most illustrious orna- ments, from Cardan to Kepler, for any absurdity, however wild and baseless, proceeding from any intellect, however powerful and profound. But there is something in this little quiet Scotch contract, entered into betwixt the best man and the worst man whom Scotland then held, more startling than the Harmonices Mundi of the imaginative German philosopher, or the folly of Tycho Brahe and his prophetical idiot. + Most of these instances of supersti- * Cunninghame of Drumquhassil was a distinguished, but not a respected, statesman, in the minority of James VI. He is mentioned as the cautioner for the philosopher’s father in two thousand pounds, when the regency confined Napier after the battle of Langside in 1568. But his fate in 1585, may account for the horror taken to his house by John Napier. Moysie thus records it :—‘ About the letter end of Januar, theare wes a conspiracie discoverit by Hamiltoun of Inchemachane, anent the taking of the king at the hunting, or careing him to the Merse, be the Erle of Angus and Maris confederates, or killing him unnaturally. Quairupone Duntreathe, Drumquhassil, and the Laird of Maynes, being teane and accusit, Duntreathe confest, and fyled ; Drumquhassel and Maines, quha wold never confes, they wer execut ; and Duntreathe spaired for his confessioun.”—P. 52. + Tycho was very superstitious. If, on going out of his house, he met an old woman or a hare, he invariably turned back. During his reign at Uraniburg he kept a fool of the name of Lep, who sat at his feet at dinner time, and was fed by the hands of the philosopher. Lep was a pro- phet, at least Tycho believed so and noted all his predictions carefully—See Tycho's Life by Gas- sendi, p. 229 ; and Memoirs of Men Illustrious in the Republic of Letters, by Niceron, T. xy. p. 170. NAPIER OF MERCHISTON. 225 tion create disgust from their extravagance, or doubt from the vagueness of the record ; but here is a page of such chastened and decent magic, so au- thentically recorded, and soberly set down by the same hand that set down the Canon Mirificus Logarithmorum, that common sense herself might pause to consider it. There is no ostentatious display of the terms of magic in the deed ; but that something romantic is meant cannot be doubted, as the words will bear no or- dinary interpretation. “ Thesaid Jhone sall do his utter and exact diligens to serche and sik out, and be al craft and ingyne that he dow, to tempt, try, and find out a soum of monie and poiss heid and hurdit up secretlie, quhilk as yit is on fund be ony man,” some where in the Dom Daniel of Fastcastle, indi- cate that the mattock and the spade had been tried in vain, and that the blackest art of the Earl of Bothwell had failed, but that there was still a hope from the power of Napier. It is nothing extraordinary that a rude and tur- bulent baron should have formed this idea; but that Napier himself should have accepted the reference, and so gravely written its conditions with his own hand, is very inexplicable in one who was most assuredly neither a charlatan, nor given to jesting with such characters as Logan ; and who is unrecorded as having displayed any public pretensions to the character of that “ Cunning man, hight SIDROPHEL, That deals in destiny’s dark counsels, And sage opinions of the moon sells ; To whom all people, far and near, On deep importances repair ; When brass and pewter hap to stray, And linen slinks out of the way.” * The Sidrophel of Butler. was none other than the famous William Lilly, who wrote the history of his own life and times. He was nearly a contem- porary of Napier’s, and well acquainted with those who knew him ; but, in his notices of our philosopher, he imputes nothing to his character beyond the * When Hudibras discomfits Sidrophel, and asserts the right of conquest by rifling his pockets, he therein finds inter alia, A moon-dial with Napier’s bones, And several constellation stones Engraved in planetary hours, That over mortals had strange powers. 226 THE LIFE OF most respectable department of the romance of science. “ Lord Merchiston,” says he, “ was a great lover of astrology, but Briggs the most satirical man against it that hath been known. But the reason hereof I conceive was, that Briggs was a severe Presbyterian, and wholly conversant with persons of that judgement ; whereas the Lord Marchiston was a general scholar, and deeply read in all divine and human histories. It is the same Marchiston who made that most serious and learned exposition upon the Revelation of St John, which is the best that ever yet appeared in the world.” * A scene was witnessed by Sidrophel himself, just forty years after Napier’s contract with Logan, which is the best illustration I can find of what may, possibly, be indicated by that curious document. “ Two accidents,” says Lilly, * happened to me in that year something memorable. Davy Ramsay, his majesty’s clock-maker, had been informed that there was a great quantity of treasure buried in the cloyster of Westminster Abbey; he acquaints Dean Williams therewith, who was also then Bishop of Lincoln; the Dean gave him liberty to search after it, with this proviso, that, if any was discovered, his church should have a share of it. Davy Ramsay finds out one John Scott, who pretended the use of the Mosaical rods to assist him herein. I was de- sired to join with him, unto which I consented. One winter’s night, Davy Ramsay, with several gentlemen, myself, and Scott, entered the cloysters.t We played the hazel-rod round about the cloyster ; upon the west side of the cloysters the rods turned one over another, an argument that the treasure was there. The labourers digged at least six foot deep, and then we met with a coffin; but in regard it was not heavy, we did not open, which we afterwards much repented. From the cloysters we went into the abbey church, where * William Lilly’s History of his Life and Times, from the year 1602 to 1681.

He seems to have been well acquainted with this anecdote, and notes, that “ Davy Ramsay brought an half quartern sack to put the treasure in.” Sir Walter Scott honours Davy too much in classification. “ Master Ramsay was often accus- tomed to retreat to the labour of his abstruse calculations ; for he aimed at improvement and dis- coveries in his own art, and sometimes pushed his researches like Napier, and other mathemati- cians of the period, into abstract science.” He also makes the scientific constructor of horologes, when irate against his apprentices, swear “ by the bones of the immortal Napier.”—Fortunes of Nigel. NAPIER OF MERCHISTON. 227 upon a sudden (there being no wind when we began,) so fierce, so high, so blustering and loud a wind did rise, that we verily believed the west end of the church would have fallen upon us. Our rods would not move at all; the candles and torches, all but one, were extinguished, or burned very dimly. John Scott, my partner, was amazed, looked pale, knew not what to think or do, until I gave directions and command to dismiss the demons ; which, when done, all was quiet again, and each man returned unto his lodging late, about twelve o’clock at night. I could never since be induced to join with any in such-like actions. The true miscarriage of the business was by reason of so many people being present at the operation ; for there was about thirty, some laughing, others deriding us; so that, if we had not dismissed the demons, I believe most part of the abbey church had been blown down. Secrecy and intelligent operators, with a strong confidence and knowledge of what they are doing, are best for this work.” * Such was the state of the art in question, in the times and in the hands of Lilly ; but we suspect it must have degenerated during the years that had elapsed since Napier practised it, from some more scientific, or at least more innocent mode of operation. What he proposed to do was by “ the grace of God ;” and had the two dark outlaws, whom he may have met at Fastcastle, required of him to exercise any control over demons, he would probably have answered in the spirit of Sampson Agonistes, I know no spells, use no forbidden arts ; My trust is in the living God, who gave me At my nativity this strength. One circumstance must be observed in reference to the characteristic trait we are considering, that Napier was brought into close and constant contact with practical operations, the most likely in the world to imbue him with all the enthusiastic fancies, then so current, upon the subject of discovering the occult recesses and properties of the precious metals. Since the year 1582, his father, Sir Archibald, had been master of the mint, with the sole su- perintending charge of the mines and minerals within the realm. In those times, the soil of Scotland was supposed to be teeming with gold and other precious metals. Mr Chalmers, in his Caledonia, informs us, that « James IV., who was a great dabbler in alchemy, appears to have * Lilly’s History, p. 78. 228 THE LIFE OF wrought some mines in Crawford-Muire. In the treasurer’s accounts of 1511, 1512, and 1513, there are a number of payments to Sir James Pet- tigrew and the men who were employed under him in working the mine of Crawford-Muire. There are also payments of wages to Sebald Northberge, the master-finer, to Andrew Ireland, the finer, and to Gerard Essemer, a Dutchman, the melter of the mine. At Wynlockhead, on the Nithsdale side of the Leadhills, a lead mine was wrought in 1512 by some of the workmen who were employed by James IV.” * The next monarch in like manner, and with greater success, patronized this royal and delightful sport. It appears from the Acta Dominorum Concilii, that in the year 1526, a company of Ger- mans obtained a grant from James V. of the precious mines in Scotland for forty-three years, and were much encouraged. Bishop Lesley declares that these foreigners worked for many months most laboriously in Clydesdale, seeming to be only employed in rolling up great balls of earth; from which, however, they enriched themselves, by extracting quantities of the purest gold.+ These operations probably introduced into Scotland much scientific knowledge on the subject, mingled with the wilder aspirations of the adept. Sir Archibald Napier seems to have forsaken his legal pursuits not many years after he held the office of justice-depute, in order to betake himself to this seducing craft; and he became the most expert man in his own country at detecting gold amid the grosser elements of creation, refining it for human purposes, and, finally, at regulating the whole preparatives of its legal cir- culation inthe realm. In the preface to a translation of the Life of James V., written in French and printed at Paris 1612, it is stated, upon the authority of a manuscript in the Cotton Library, that, “ In King James the Fifth’s time, 300 men were employed for several summers in washing of gold, of which they got above L. 100,000 of English money. By the same way, the Laird of Merchiston got gold in Pentland Hills.” + I have not had the advantage of inspecting the manuscript ; but there can be no question that this was the father of our philosopher. In the Balcarres collection of original manu- scripts, belonging to the Advocates’ Library, there is a mass of papers relating to the “* Cunzie” of Scotland, in which the names of Sir Archibald Napier and his son Francis figure very conspicuously. From these it appears, that, * Caledonia, Vol. ii. p. 732. + De Rebus Gestis Scotorum.

The same act bears, “ That forsa- mekle as Thomas Foullis, gouldsmyth, has found out the ingyne and moyene to caus melt and fyne the vris (ores) of metallis within this cuntrie, and hes brocht in strangearis,” &c.; therefore ratifies to him the gift of “ the said melting and refyning of all and quhatsumevir vris of metallis won and wrocht within this countrie,” &c. These proceedings gave great offence to Sir Archibald Napier, who seems to have viewed the whole matter in the light of a rash experiment on the part of the king, at the instigation of those who had nothing in view but their own private interests, and no knowledge or experience in the particular craft. He accordingly opposed these measures in his place in Parliament, and re- corded a formal protest against them.{ Besides this, he drew up for the * In the year 1587, “ Sir Archibald Naper of Edinbellie, Knicht, Generall of his Hienes Cunze-Hous,” is joined in commission with his cousin-german, “ Sir Robert Melville of Murdo- cairnie, Knicht, Thesaurare-depute,” and a few others, whose ordinance is to have the force of an act of Parliament, “ for setting of the quantitie of the bulzeon to be brocht to the cunze-hous” for all manner of exported goods liable to custom.—Acts of the Scottish Parl. + John Lindsay, commonly called Parson of Menmure, from holding that rectory, was the second son of Sir David Lindsay of Edzell and Glenesk, and the father of David first Lord Lindsay of Balcarras.

To the first head, “‘ quhair the said Thomas suld big ane strong and lairge hous upone his awin expensis; for an- seir heirto; gif it be upone Thomas awin expensis we querrell it not ; bot gif it be upon his majesties, as appeiris be the letter pairt of the said act, we think that bigging to be sumptuous and inuteill; be ressoun the money micht be affynit in ony convenient hous in Edinburgh.” He expresses great misgivings as to the public utility of the scheme, “ and thairfoir,” says he, “ we desyre your Lordschippis to inquyre of the said ‘Thomas quhat free proffeit his ma- jestie will ressave upone ilk stane wecht being affynit and prentit, all maner of deductions being deduceit ; and thairefter we sall latt your Lordschippis un- derstand ane uther plat concerning the money, quairupone his hienes and your Lordschippis may juge, and tak the best and maist proffitable.” He doubts exceedingly the affyning qualifications of Foulis and his strangers ; and urges that “ the said affyning aucht to be maid in presens of the wardens and essayer of the Cunziehous onlie; for gif sum controlement heirof be not usit be the maist expert of the Cunziehous, the saids effyneris may mak mair nor x]™ pundis [L. 40,000] of proffeit to thameselffis, and never kennell ane fyre for effyning thairof.

In like manner Sir Archibald canvasses very severely the act of appoint- ment in favour of Mr John Lindsay; and from his strictures, also among the jestie’s Cunzehous, that na collectoire be appointit over the ingaddering of his Majestie’s deutie of the mynis, except the Generall of his Majestie’s cunziehous ; and that becaus it is ane pairt of the said Generallis office, quhereof he and his predicessouris generallis hes bene hitherto in use.”— [1592.] Acts of Parl. iii. 559. NAPIER OF MERCHISTON. 231 Balcarres papers, we find some minute particulars in reference to his own craft and a history of the mines and the mint of Scotland.* He contrasts the terms of the old leases with the schemes now proposed, which, he does not hesitate to affirm against Mr Lindsay, are “ ane substantius ground to mak himself ane havie purs.” He informs us, that “ the mynis hes bene sett heir- tofoir to Johnne Achesoun and John Coslon ; and to James Johnstoun of Kel- liebaukis, Cornelius de Vos, George Douglas of Parkheid, Abraham Petersoun, his pertineris, and Mr Eustatius,” upon terms much more advantageous to the king and country than those contained in the new act; and he adds, “ I find na commoditie be this act to the finder, nochtwithstanding it wer the kingis majesties profit to appoint ane ressonabill portioun thereof to quhat- sumever man that wald discover ony myne.” Speaking of himself, he says, “there is ane officiar appointed alredde, quha hes the oversycht of the mynis, hes servit and presentlie servis therinto, gadderis up the king’s dewties thairof, and being commanded, will serve therintill upon his accustomet wages; evin the generall of the Cunziehous, quha is redde to abyd tryell of his qualifica- tioun.” His qualification seems to have been the result of assiduous practice and great experience, in the course of which the attention of his philosophical son must have been more or less attracted to these matters. In asserting his own right to be master of the metals, exclusive of Lindsay, he adds, “ the present maister of the mettallis, to wit, the generall of the Cunziehous hes thir money * There is a very full and curious manuscript entitled “ The Discovery and Historie of the Mynes in Scotland” among the MSS. of Sir Robert Sibbald belonging to the Advocates’ Library ; written in a wild fantastical strain, but full of minute and interesting information. It was printed for the Bannatyne Club, with copious notes and illustrations, by Gilbert Laing Meason, Esq. in 1825, and is one of their rarest, consequently most valuable, volumes. It ought to be reprinted with the additional illustrations to be obtained from the Balcarres MSS. In the notes I find it said, “ It is not very clear who the foreigner was alluded to in an act of Parliament, 5th June 1592, as then enjoying a lease of the gold mines, although it may probably have been Bronckhorst,” p- 110. Sir Archibald Napier’s papers, however, in the Balcarres collection, prove that it was “ Eus- tathius Roghe Mediciner,” who had been tacksman under Merchiston since the year 1584. The privy-council took Sir Archibald’s opinion as to the force and effect of this tack in reference to the act in favour of Lindsay ; who returned for answer, that it was absolutely necessary to reduce the tack, and pointed out the proper grounds upon which to libel the summons. An action was raised accordingly, in which, inter alva, it is narrated against the defender, that, “ being ane stranger of evill fame at hame in his awin cuntre, hes manifestlie circumventit us,” &c. The tack was re- duced. 232 THE LIFE OF yeiris bygaine, be himself and his deputis merkit barrellis, keippit register of the quantitie, and hes gevin up to the kingis majesties thesaurer compt of all the (ores) of mettallis, as heirtofoir hes bein transportit out of the cuntre.”— “ Let the generallis qualificatioun be conferrit with Mr Johnne Lindsayis in this facultie, and quhilk of them can baith gif best resounis and work it with thair handis, (utherways thei may be decavit,) have this office.” The gene- rall can and will quhenever he is chargit, baith work in small and greit, and hes lernit utheris to do the same als perfytlie, and with less expensis nor ony strangaris that sall cum within this cuntre is hable to do.” * The parson of Menmure had no idea of submitting quietly to these animad- versions, and, accordingly, recriminates very much in the style of a modern reformer attacking one whom he alleges to be growing fat upon old abuses. When Sir Archibald’s sharp-sightedness seems to have penetrated too far, Lind- say observes, “ it mervelis me quhou Merchinstone can have onie ground or fundament of his rakning,” &c. “ except it be be the spirit of divination ;” a gibe he is very fond of casting at the laird, for he repeats, “ this is founded upon the spirit of divination, propheticallie affirming,” &c. “ I will answer conforme to the Scripture, that gif the contrarie be found in effect, lat that prophet be estemit untrew,” &c. He then rides rough-shod over Sir Archibald’s experience; “ he may be weill better versit in bellices and fornaces nor I, and sua have mair knauleg; bot vertu is in action, and noth in contemplatioun ; and I believe that I sall schaw better effect of my office in ane year nor he hes done in nyne ;” and, finally, he adds, what will give us a more complete, though somewhat distorted, view of the vocation of our philosopher’s father: “ To con- clude, I desyre your Lordships to tak the general’s gryt aith upon sik sems of metals as he hes found, and knawis to be in Scotland ; of the profit quherof it is na resone that his majestie and the cuntrie sould be defraudit be his malicius si- lence; and gif he sweris that he knawis nain, I wilofferto prove that divers tymes he hes avowet that he knawis and hes tentit ane copper sem neir the sie, fyve myle lang, quhilk sem I will be content to have in tak, or oni uther sem quhilk he hes found, he making ane resonable offer to the king of the fourt pairt free, * Sir Archibald also says, “ Mr Johnne Lindsay and Thomas Fowlis hes leid subtill platis to bring the haill mynis of this cuntrie in thair awin hands allanerlie ;” and he concludes, “ I prey you my Lordis gif attendence to the subtill mening of this act, and provyd remeid thairfor in tyme ; utherwyis the burdein therof lyes upoun your Lordschips ; for I haif exonerat myself heir to your Lordships ; and also in Parliament be my protestatioun tane in the contrair of this present act.” Balcarres Papers, Vol. ix. ro NAPIER OF MERCHISTON. 233 quhilk he sayis wes the auld dewtie, or oni uther dewtie quhilk your Lordships sall find reasonable.

Balfour records, that upon the “ 10 September 1604, Napier, Laird of Merchistoun, General of the Cunzie House, went to London to treat with the English commissioners anent the cunzie, who, to the great amazement of the English, carried his business with a great deal of dexterity and skill ; and, having concluded the business he went for, he returned home in Decem- ber thereafter.”. By what particular display of the golden art he amazed the * It is curious to observe that both Lindsay’s son, and Sir Archibald’s grandson, wrote on the occult sciences. It is mentioned by Mr Wood in the peerage, quoting the Lindsay MSS. and speaking of David first Lord Lindsay of Balcarres, “ there is in the library at Balcarres ten vo- lumes wrote by his own hand, upon the then fashionable subject of the philosopher's stone.” Ro- bert Napier’s treatise on the same subject is noticed p. 236. + Balfour’s Annals, MS.

These were printed some years since in three vols. 8vo, by Messrs Haig of the Advocates’ Library. 2 234 THE LIFE OF savans of the sister kingdom is not recorded; but the matter seems to have attracted universal attention, for honest Robert Birrell in his contemporary diary thus notes the occurrence: “ The 10th of September, the General Mais- ter of the Cunziehous tuik shipping to Lundone, for the defence of the Scot- tis cunzie befoir the counsell of Ingland, quha defendit the same to the uttir- most; and the wit and knawledge of the General wes wunderit at be the Eng- lischmen.” Thus, independently of the natural leaning of a profound mind (in days when the limits of human power were not so clearly defined as now) towards the oc- cult sciences, our philosopher had to sustain unusual temptations from his daily contact with the mysteries of mining, and the brilliant hopes and tempting jargon of the searchers for gold,—with their “ saxere stones,” and *‘ calamineere stones,” and * salineere stones as small as the mustard seede, and some like meall; and the sappar stone in lumps, like unto the fowles eyes, or bird’s eggs; and, the most strangest of all, naturall gold linked fast unto the sapper stone, even as vaines of lead-ewer and white sparrs doe growe togea- ther,” *—and all this in Scotland before the seventeenth century! The wonder is not that he was infected with what we have ventured to call the romance of science, but that all his writings, theological and philosophical, should be en- _tirely free from a vestige of such propensities. Whatever pranks he may have played in the cellars at Fastcastle, the moment he set fairly to work with his head, it grew clearer the more profound it became, and cooler the further it penetrated. The superstition so subdued in him was decidedly manifested in many of his contemporary relatives. His uncle the Bishop of Orkney was said to be a “ sor- cerer and execrable magitian.” + Of this there is scarcely sufficient proof; but * Stephen Atkinson’s MS. on the gold mines in Scotland.

It was in sternes, and some like unto bird’s eyes and eggs; he compared it unto a woman’s eye, which intiseth hir joyes into hir bosome.” + There has been lately discovered in the Register House a Scotch MS. chronicle, embracing an apology for Queen Mary, and an exposure o¢ the faction by which she was destroyed. The 3 NAPIER OF MERCHISTON. 235 his cousin Sir James Melville, who had seen the world under every aspect and breath of Heaven, was an unhesitating believer in necromancy, though he ne- ver practised it. He narrates among his youthful adventures, that, while un- der the charge of the Bishop of Valence in Paris, before becoming the secre- tary of Montmorency, two great scholars and mathematicians, Cavatius and Taggot, frequented the bishop’s house. Cavatius gravely informed the pre- late that there was an old shepherd in Paris to whom had been bequeath- ed the singular legacy of two familiar spirits, from a priest whose servant the shepherd had been. Valence thought this so great a curiosity that he led the mathematician into the presence of Henry II. before whom Cavatius offered to lose his head, if he did not produce those very spirits, either in the shape of dogs or cats, as might be most agreeable. But the king took a very sensible, though unexpected view of the matter; “ he caused burn the schephird, and imprisonit the said Cavatius, and wald not see the saidis spritis.” As for Taggot, “ he,” says Melville, “ had learnit be the art of palmestrie, as he said to me himself, that he wald die before he atteanit unto the age of twenty-eight years. Wherfore, said he, I know the trew religion to be exercysed at Gene- va; there will I go and end in Godis service. Sa he did, and died ther at Lausan, as he had conscavit the opinion; as I gat word afterwart.” This was in the year 1553. Six years afterwards, when Melville was returning to France from his first embassy to Scotland, he “ fell in company with ane Eng- lishman, wha was ane of the queenis varletis of hir chamber; a man learnit in mathematik, necromancye, astrologie, and was also a gud geographe.” This man entertained Melville with a long story about Harry VIII. having been “ sa curious as till enquyre at men callit devyners and negromanciens, what suld becom of his sone K. Edward 6. and of his twa dochters Mary and Elysabeth ;” and that all their fate had been accurately foretold. “ This,” says Melville, “ the honest man affirmed to be true, and not knawen till language and expressions clearly indicate a contemporary production. Speaking of the conyen- tion of estates after Mary’s forced abdication, this writer says “ they caused thither to come to re- present the ecclesiastical estate and spiritualitie, the venerable, often perjured and foirsworne fa- ther, Mr Adam Boithwell, whom, for this purpose, they befoirhand helped to be made Bischope of the Orcades, a camelion, a sorcerar, and evecrable magitian,’ &c. For the perusal of this cu- rious manuscript, which seems to be either the original, or a contemporary translation of Adam Blackwood’s Martyre de Maria Stuart, I am indebted to the never-failing attention of Mr Macdo- nald of the Register House. 236 THE LIFE OF many. He was a man of gret gravitie, about fifty years of age; and when we cam to London, he schew me gret courtesie, and made me presents of some bukis.” Our philosopher had another cousin who actually died of fright at the result of an incantation. Sir Lewis, the son of Sir John Bellenden, though quite a youth when his father died, stepped immediately into his office and state career. After he had become experienced and notorious as a statesman, he chose to have dealings with that dangerous person Richard Graham, of whose evil company Francis Earl of Bothwell was accused. In the year 1591, the justice-clerk, “ by curiosity dealt with a warlock called Richard Graham to raise the Devil, who having raised him, in his (Bellenden’s) own yard in the Canongate, he was thereby so terrified that he took sickness and there died.” * Robert Napier, the philosopher’s second son of his second marriage, and through whom his lineal male representation is now held,+ affords a re- markable instance of the superstition of the family ; and this is curious, as he was the favourite son to whom John Napier bequeathed the care of his younger children, and the editorial charge of his unpublished works. Among the Merchiston papers I find a thin quarto volume in manuscript, closely writ- ten in the autograph of Robert Napier. It is addressed to his son, and upon the first leaf appears an injunction which we may presume to be now entitled to as little consideration as a freehold superiority in Scotland since the act of the Reform Parliament. “ This book to remaine in my charter-chist, and not to be made knowne to any except to some neir freind, being a scholler, studious of this science, who feares God, and is endewed with great secrecie not to re- veil and mak commune such misteries as God hes apointed to be keipit secrit among a few in all ages, whoes harts ar upright towards God, and not given to worldly ambitione or covetousnes, but secretly to do gud and help the poor and indigent in this world, as they wold eschew the curse of God if they do otherways, | “ R.

NAPIER OF MERCHISTON. 237 The book is in Latin, and consists of a digest of all that is precious in alchemy or hermetic philosophy, being a revelation of the mystery of the Golden Fleece. It commences with a solemn address to his son. He tells him, “ above all things embrace God with your whole heart and purity of mind; for without his guidance all is vanity, and especially in this divine science.” He then strongly inculcates secrecy as the first essential duty of the hermetic art; “a madman,” says he, “ must not have a sword, and were these secrets to be di- vulged, the hind would become greedy of gold to his own destruction, and ini- quities would cover the earth; mighty in their gold, nations would rush to war for nothing ; the worthless would wax proud and scorn their rulers ; and the reins of civil power and legitimate government being relaxed, an earth- quake would follow. Oh! I say, reveal this secret to the vulgar, and the darkness of chaos shall again brood upon the face of the waters.” Having thus enjoined secrecy, Robert Napier of Culcreuch, Esq. proceeds to give his reasons for pointing out to his son the path to the precious elixir ; namely, that he might not waste his time in consulting books that would lead him astray, or ruin himself with the expences of an ill-directed search; and having sketch- ed the plan of his work he thus concludes: ‘“ But, above all things, you my son, or whoever he be of my posterity who may chance to see and read this book, I adjure by the most holy Trinity, and under the pains of the curse of Heaven, not to make it public, nor. to communicate it to a living soul, unless it be to a child of the art, a good man fearing God, and one who will cherish the secret of Hermes under the deepest silence. But if thou dost otherwise, accursed be thou! and, guilty before the throne of God, may every pain of that condemnation follow thee which Heaven in its wrath will visit upon him who reveals the shrine of Hermes to unhallowed eyes. God grant that my soul may be free from so deadly a sin; and, imploring him that no malign influ- ence may direct this book into impious hands, I take his holy name to witness that I have written it only for the sake of the good, those who with sincere and pious hearts worship him, to whom be the honor, the praise, and the glory for ever and ever.” * * The title of the MS. is “ Mysterii aurei velleris Revelatio; seu analysis philosophica qua nucleus vere intentionis hermeticz posteris Deum timentibus manifestatur. Authore R. N.” And its motto, _ Orbis quicquid opum, vel habet medicina salutis, Omne Leo Geminis suppeditare potest. 238 THE LIFE OF The reader will excuse our penetrating farther into a work with so fearful a preface; but so much we may afford him, without falling under the ana- thema maranatha of this disciple of Hermes, as a very curious picture of the times, derived from one under whose auspices was published the revelation of a more humble secret,—his father’s secret method of constructing the Lo- garithms. In the Ashmolean Museum, Oxford, there is an original picture of Dr Ri- chard Napier of necromantic memory, which in some features bears so strong a resemblance to the portraits of our philosopher, that they might easily pass for brothers. ‘The relationship is not quite so close, though very nearly, as they were brothers’ sons,—a fact not generally known. Alexander Napier of Merchiston killed at the battle of Pinkie, and who was so frequently abroad, had a son named Alexander, who came immediately after his eldest son Archi- bald, the philosopher’s father. Alexander seems to have accompanied his father in some of his foreign excursions, and was left by him in England, probably at school, before the year 1548. Instead of returning to his country, young Alex- ander Napier established himself in Exeter, and married an English lady, Ann, a daughter of Edward Birchley, Esq. of Hertfordshire. Of this marriage there were two sons; Robert, the Turkey merchant, who became a baronet, as we have elsewhere particularly noted, and Richard, whose history and ad- ventures we shall now sketch. He was about eight years younger than the philosopher, and seems to have obtained all the advantages of a classical education; was fellow of Exeter Col- lege, Cambridge,—took a degree in that university,—and became rector of Lynford. In his youth, however, he attached himself to one of the lights of the Rosicrucian school, Dr Simon Forman. This celebrated adept, who, among many works of the kind, published one on the art of discovering hidden trea- sure and goods purloined, was rather successful as a physician, but much more soasacheat. His character and occupations cannot be better displayed to the reader than in a single sentencé.written by himself in one of the books he left behind him, viz. ‘‘ This I made the Devil write with his own hand in Lam- beth Fields, 1596, in June or July, as I now remember.” Under such auspices, it is not surprising if Doctor Richard Napier far excelled his Scotch cousin in the occult sciences. William Lilly, speaking of Forman’s death, says, “ all his rarities, secret manuscripts of what quality soever, Dr Napper of Lindford in Buckinghamshire had, who had been a long time his scholar; and of whom NAPIER OF MERCHISTON. 239 Forman was used to say he would be a dunce; yet in continuance of time he proved a singular astrologer and physician.”* The same author, who was personally acquainted with Richard Napier, adds, that his “ family cam into England in King Henry the Eighth’s time.+ The parson was master-of-arts ; but whether doctorated by degree, or courtesy because of his profession, I know not. Miscarrying one day in the pulpit, he never after used it; but all his lifetime kept in his house some excellent scholar or other to officiate for him, with allowance of a good salary. He outwent Forman in physic and holiness of life ; cured the falling sickness perfectly by constellated rings ; some diseases by amulets, &c. A maid was much afflicted with the falling-sickness, whose parents applied themselves unto him for cure. He-framed her a constellated ring, upon wearing whereof she recovered perfectly. Her parents acquainted some scrupulous divines with the cure of their daughter; ‘ the cure is done by inchantment,’ say they ; ‘ cast away the ring, it’s diabolical; God cannot bless you if you do not cast the ring away. ‘The ring was cast into the well, whereupon the maid became epileptical as formerly, and endured much misery for a long time. At last her parents cleansed the well, and recovered the ring again; the maid wore it, and her ‘ fits’ took her no more. In this condition she was one year or two; which the puritan ministers there adjoining hear- ing, never left off till they procured her parents to cast the ring quite away ; which done, the fits returned in such violence that they were enforced to apply to the doctor again, relating at large the whole story, humbly imploring his once more assistance; but he could not be procured to do anything, only said, ‘ those who despised God’s mercies were not capable or worthy of enjoying them.’ I was with him in 1632 or 1633 upon occasion. He had me up into his library, being excellently furnished with very choice books ; there he prayed almost one hour ; he invocated several angels in his prayer, viz. Michael, t Ga- * Lilly’s Life and Times, p. 44. + There were two distinct branches of the Napiers of Merchiston in England. James, a younger son of Archibald fourth of Merchiston, settled in England in the reign of Henry VII. His sons all founded wealthy and distinguished families, and his grandson was Lord Chief Baron of Ireland. Through him various noble families are lineally descended from Sir Alexander Napier of Philde and Merchiston. James Lenox Napier of Ireland became Lord Sherbourn. His son married the daughter of Lord Stawel; one of his daughters married Viscount Andover, son and heir of Charles Earl of Suffolk; and another daughter married Prince Bariatiusky of the Russian Empire.—See Note A, as to the English and Irish Napiers cadets of Merchiston. { Elias Ashmole here notes, “ At some times, upon great occasions, he had conference with Michael, but very rarely.” 240 THE LIFE OF briel, Raphael, Uriel, &c. We parted. He instructed many ministers in as- trology ; would lend them whole cloak-bags of books; protected them from harm and violence by means of his:power with the Earl of Bolingbroke He would confess my master Evans knew more’ than himself in some things; and some time before he died; he got: his cousin Sir Richard to set a figure to see when he should die.. Being brought to him, ‘ well,’ he said, “ the old man will live this winter, but'in the spring he will die; welcome Lord Jesus, thy will be done. He had many enemies; Cotta, doctor of physick in Northampton, wrote a sharp book of Witellorakt; wherein obliquely he bitterly inveighed against the doctor.” * Thus far Sidrophel. But I find Doctor Napier still more curiously recorded by John Aubrey in his quaint volume of Miscellanies, and under the attractive title, “ CONVERSE WITH ANGELS AND SPIRITS.” “ Dr Richard Nepeir-was a person of great abstinence, innocence, and piety ; he spent every day two hours in family prayer. When a patient or querent came to him, he presently went to his closet toypray, and told to admiration the recovery or death of the patient.. It appears by his papers, that he did converse with the angel Raphael, who-gave him the responses. Elias Ash- mole, Esquire, had all his papers, where is contained all his»practice for about fifty years, which he, Mr Ashmole, carefully bound up, according to the year of our Lord, in volumes in folio, which are now reposited in the library of the museum in Oxford. Before the responses stands this mark, viz. R. Bis, which Mr ‘Ashmole said was Responsum Raphaelis. In these papers are many excellent medicines or receipts for several diseases that his patients had, and before some of them is the aforesaid mark. Mr Ashmole took the pains to transcribe fairly with his own hand all the receipts. They are about a quire and half of paper in folio, which since his death were bought of his relict by +E. W. Esquire, R.S.S. The angel told him if the patient were curable or incurable. There are also several other queries to the angel as to religion, transubstantiation, &c. which I have forgot. I remember one is, Whether the good spirits or the bad be most in number ? Responsum Raphaelis, The good. It is to be found there that he told John Prideaux, D. D. anno 1621, that twenty years hence, 1641, he would be a bishop, and he was so, sc. Bishop of Worcester. Raphael did resolve him, that Mr Booth of in Cheshire, should have a son that should inherit three years hence, (sc. Sir George Booth, * Lilly’s Life and Times, p. 123. + Edward Waller.

This I extracted out of Doctor Nepeir’s ori- ginal diary, then in possession of Mr Ashmole. When E. W., Esquire, was about eight years old, he was troubled with the worms. His grandfather car- ried him to Doctor Nepeir at Lynford. Mr E. W. peeped in at the closet at the end of the gallery, and saw him upon his knees at prayer. The doctor told Sir Francis, that at fourteen years old his grandson would be freed from that distemper, and he was so. The medicine he prescribed was to drink a little draught of muscadine in the morning. “T'was about 1625. It is impos- sible that the prediction of Sir George Booth’s birth could be found any other way but by angelical revelation. This Doctor Richard Nepeir was rector of Lynford in Bucks, and did practice physick ; but gave most to the poor that he got byit. *Tis certain he told his own death toa day and hour. He dyed praying upon his knees, being of a very great age, 1634, April the first. He was nearly related to the learned Lord Nepeir, Baron of M............ in Scot- land, I have forgot whether his brother. His knees were horny with frequent praying. He left his estate to Sir Richard Nepeir, M. D. of the College of Physicians, London, from whom Mr Ashmole had the doctor’s picture now in the museum. He was a good astrologer.” * The Sir Richard Napier last-mentioned was a nephew of Doctor Richard, and younger son of Sir Robert Napier of Luton-Hoe, Bart., the Turkey merchant ; consequently, he was first cousin once removed to John Napier of Merchiston. Sir Richard was first of Wadham College, Oxford, and afterwards fellow of All- Souls, and took his degree as doctor of physic. “ Hewas,” says Anthony a Wood, * one of the first members of the Royal Society,—a great pretender to virtue and astrology,—made a great noise in the world, yet did littleor nothing towards the public.

There is also a curious collection of letters from eminent persons in the seventeenth and eighteenth cen- tury, published under Aubrey’s name, from the originals in the Bodleian Library and Ashmolean Museum. He was a great friend and source of information to the well-known Anthony a Wood, author of the Athenz and Fasti Oxoniensis. Wood, in his Life of Judge Jenkins, threw some reflection upon Lord Clarendon, for which he (Wood) was expelled from Oxford; but he afterwards declared that he had it from Mr Aubrey, who had it from Judge Jenkins himself. Anthony used to say of Aubrey, “ Look, yonder goes such a one, who can tell such and such stories ; and I’le warrant Mr Aubrey will break his neck down stairs rather than miss him, —— Hearne.

The said Sir Richard drew up a book containing a collection of nativities, which is now in MS., in the hands of Elias Ashmole, Esq.” * Aubrey gives this curious account of his death :— “ When Sir Richard Napeir, M.D. of London, was upon the road coming from Bedfordshire, the chamberlain of the inn shewed him his chamber. The doctor saw a dead man lying upon the bed; he looked more wistly, and saw it was himself! He was then well enough in health. He goes forward in his journey to Mr Steward in Berkshire, and there died. This account I have in a letter from Elias Ashmole, Esq. They were intimate friends.” + Had our philosopher in any degree partaken of the wild absurdities which characterized his cousins in England, the probability is that some traces of a correspondence betwixt them would be found among the papers of Dr Napier at Oxford, which, however, is not the case; and when we compare all that appears of John Napier’s fanciful vein, not merely with that of contemporary philosophers, historians, and statesmen, but with the members of his own family, and the cadets of his house, we are led to conclude, that in him astro- logical and rosicrucian superstitions were subdued in the proportion that his science predominated. When not absorbed in his deep contemplation of the Scriptures, or his purely abstract speculations in mathematics, we shall show that he was better employed than in framing constellated rings for the vulgar, or teaching the Devil to write. But the picture we have now to afford of him deserves to be the subject of a separate chapter. * Wood's Fasti Oxonienses. By Bliss. Part Second, p. 47. + Miscellanies, p. 91. NAPIER OF MERCHISTON. 243 CHAPTER VII. ANOTHER view may be taken of what possibly was the result of our phi- losopher’s contract with Logan, than that he had actually gone to Fastcastle, and been cheated or robbed by its sinister possessor. The Popish Lords, against whom Napier had just been so active and public an instrument, were, after much shuffling on the part of James, again brought before the tribunal of their country. In the month of June 1594, the intercepted blanks and other treasonable papers were produced and verified in Parliament, where a rigo- rous sentence of forfeiture for high treason passed against the delinquents, with every circumstance of favour to the Protestant cause which had been desired by the Assembly of the Church. The consequence was, that these noblemen were driven to extremities, and they received at this time the accession of the unprinci- pled Earlof Bothwell, who, like them, could find amid the fast-flowing tide of the king’s reformation and justice, no spot to stand on save the most towering treason. They took the field accordingly in great force, with the secret co- operation of Bothwell; and the king sent the young Earl of Argyle to meet them, who sustained the signal defeat at Belrinnes, known by the name of the Battle of Glenlivet, which occurred in October 1594. It was in the intermediate month of July betwixt the forfeiture of the Popish Earls and the date of their victory, that Napier was invited to Fastcastle; and as we see that the Earl of Ar- gyle considered supernatural powers an essential ingredient of his matervel, it is not impossible (what idea is too extravagant for the times and the actors *) * The Latin historian of the battle of Glenlivet, who seems to have been an eye-witness, says, that Argyle’s sorceress spread a thick darkness around them, but that all her incantations failed, because, as she herself confessed when taken prisoner, there was something in the Catholic camp 244, THE LIFE OF that his enemies considered it advisable to lay a plot to cripple his corps @armée, by the seizure of the marvellous Merchiston. It might also have been intended to bring the laird to a very serious reckoning at Fastcastle on his own account, his host being one more ready to discuss reasons of ransom than of religion. Our philosopher’s better genius may have opened his eyes to some such scheme against himself and his party, and thus have prevented his falling into the same suare so soon afterwards spread for the king himself. We see his subsequent indignation against the very name of Logan ; and cer- tainly if he went to Fastcastle at this crisis, he must have escaped from it by a miracle. That all eyes were attracted to him at the time, as one able to do more than any other single individual to protect his country from insidious enemies and foreign invasion, is evinced by other of his operations, the history of which is not generally known. Sir Thomas Urquhart of Cromarty, in a tract which he entitled, “ The Dis- covery of a most Exquisite Jewel, more precious than diamonds inchased in gold,” &c. speaks of a Colonel Douglas, who, he says, was very serviceable to the States of Holland, and presented them with a paper, containing “ twelve articles and heads of such wonderful feats for the use of the wars both by sea and land, to be performed by him, flowing from the remotest springs of mathe- matical secrets, and those of natural philosophy, that none of this age saw, nor any of our forefathers ever heard the like, save what out of Cicero, Livy, Plutarch, and other old Greek and Latin writers we have couched, of the ad- mirable inventions made use of by Archimedes in defence of the city of Syra- cusa, against the continual assaults of the Roman forces both by sea and land, under the conduct of Marcellus.” Sir Thomas then introduces his celebrated episode of Napier of Merchiston and Crichton of Elliock, whom he classes to- gether as the Castor and Pollux of Scottish letters. “ To speak really,” says he, “ I think there hath not been any in this age of the Scottish nation, save Neper and Crichtoun, who, for abilities of the mind in matter of practical inventions useful for men of industry, merit to be compared with him: and yet of these two (notwithstanding their precellency in learning) I would be altogether silent (because I made account to mention no other Scottish men here, but such as have been famous for souldiery, and brought up at the school which impeded all her efforts ; “ irrito incepto destitit, eo quod, (ut capta dicebat)) aliquid in nos- tris esset castris quod conatus ipsius vehementer impediebat.’”—MS.

NAPIER OF MERCHISTON. 245 of Mars) were it not, that, besides their profoundness in literature, they were inriched with military qualifications beyond expression. As for Neper, (other- ways designed Lord Marchiston) he is for his logarithmical device so com- pleatly praised in that preface of the author’s, which usher’s a trigonometrical book of his, intituled, The Trissotetras,* that to add any more thereunto, would but obscure with an empty sound, the clearness of what is already said : therefore I will allow him no share in this discourse, but in so far as con- cerneth an almost incomprehensible device, which being in the mouths of the most of Scotland, and yet unknown to any that ever was in the world but himself, deserveth very well to be taken notice of in this place ; and it is this: he had the skill (as is commonly reported) to frame an engine (for invention not much unlike that of Architas Dove) which, by vertue of some secret springs, inward resorts, with other implements and materials fit for the purpose, in- closed within the bowels thereof, had the power (if proportionable in bulk to the action required of it (for he could have made it of all sizes) to clear a field of four miles circumference, of all the living creatures exceeding a foot of height, that should be found thereon, how near soever they might be to one another ; by which means he made it appear, that he was able, with the help of this machine alone, to kill thirty thousand Turks, without the hazard of one Christian. Of this it is said, that (upon a wager) he gave proof upon a large plain in Scotland, to the destruction of a great many herds of cattel, and flocks of sheep, whereof some were distant from other half a mile on all sides, and some a whole mile. ‘To continue the thread of the story, as I have it, I must not forget, that, when he was most earnestly desired by an old acquaint- * Sir Thomas Urquhart’s address to the reader in that strange work entitled Trissotetras, &c. occupies two quarto pages, and is from beginning to end a panegyric upon Napier. It commences, « To write of trigonometry, and not make mention of the illustrious Lord Neper of Marchiston, the Inventor of Logarithms, were to be unmindful of Him that is our daily benefactor,” &c. He also says most justly, “ the philosopher’s stone is but trash to this invention, which will always be accounted of more worth to the mathematical world than was the finding out of America to the King of Spain, or the discovery of the nearest way to the East Indies would be to the northerly occidental merchants ;” and he concludes by recommending the “ imitation of that admirable gentleman, whose immortal fame, in spite of time, will outlast all ages, and look eternity in the face.” Sir Thomas Urquhart was born a few years before Napier died. A complete edition of his works, which may be expected to be well illustrated, is now in the press for the Maitland Club of Scotland. It is a curious genealogical fact, of which this author was not aware, that the respec- tive fathers of his two idols, Napier and Crichton, married (their second wives) about the same time (1571-72) sisters, namely, the daughters of John Mowbray of Barnbougall. Pa 246 THE LIFE OF ance, and professed friend of his, even about the time of his contracting that disease whereof he dyed, he would be pleased, for the honour of his family, and his own everlasting memory to posterity, to reveal unto him the manner of the contrivance of so ingenious a mystery ; subjoining thereto, for the bet- ter perswading of him, that it were a thousand pities, that so excellent an in- vention should be buried with him in the grave, and that after his decease nothing should be known thereof: his answer was, That for the ruin and overthrow of man, there were too many devices already framed, which if he could make to be fewer, he would with all his might endeavour to do; and that therefore seeing the malice and rancor rooted in the heart of mankind will not suffer them to diminish, by any new conceit of his the number of them should never be increased. Divinely spoken, truly.” The knight of Cromarty’s compositions are written in such a strain that it is no easy matter to determine whether he meant to speak truth jestingly, or to tell lies in downright earnest ; and we would hardly have ventured to quote this extraordinary story, were it not susceptible of very curious illustration. Their success at the battle of Glenlivet gave great encouragement to the Popish Lords ; but they were unable to cope with the royal banner, and re- treated abroad. Philip of Spain, however, still adhered to his lawless projects for the conquest of Britain; and in the year 1595-6, another crisis arrived very similar to that in which Napier was so conspicuous two years before. While Huntly, Angus, and Errol were yet abroad, the news arrived in Scot- land in the month of April 1596, that a Spanish army of 25,000 had assaulted and won Calais; and that an English army of 30,000 had entered Spain, and taken signal revenge upon the city of Cadiz. Previous to this the greatest ex- citement prevailed in Scotland from the terror of a Catholic invasion, and Wap- pin-schaws, for the universal practice of arms, were everywhere assembled by the express orders of government. That Napier, at least since the detection of the Spanish plot, had deeply occupied himself in the construction of unknown in- struments of war for the protection of his country, is proved by the scantlings or summary of his inventions, which at that time he had drawn up, and which appears also to have been presented to the English government by some of James’ ambassadors, who were sent with offers of co-operation to all Christian kings against the enemies of the Gospel. In the “ Historie of James the Sext,” it is narrated, that “ in the end of this yeir, (1595) the king being informit NAPIER OF MERCHISTON. 247 that the Ture was entrit Christendome with a potent armie, and his majestie having favour to the Christien cause and glorie of Chryst, thought expedient to direct a condigne messinger unto the emperor, and that was William Stew- art, Lord of Pittinweme, and knycht of Houston,* with letters, declaring that his majestie was glad to understand his forwartnes in that gude cause, and tharefore he promeist to mak sik assistance as he could in that purpose, to de- bell the great ennemie to our Salviour Chryst,” &c. Now, there is yet pre- served in the Bacon Collection in Lambeth Palace the following document, of which, through the liberality of its noble possessor, I am also enabled to pre- sent the reader with a fac-simile. “ Anno Domini 1596, the 7 of June, Secrett Inventionis, proffitabill and ne- cessary in theis dayes for defence of this Iland, and withstanding of stran- gers, enemies of God’s truth and religion. “ First, the invention, proofe and perfect demonstration, geometricall and alegebricall, of a burning mirrour, which, receving the dispersed beames of the sonne, doth reflex the same beames alltogether united and concurring priselie [precisely | in one mathematicall point, in the which point most necessarelie it ingendreth fire, with an evident demonstration of their error who affirmeth 2. this to be made a parabolik section. “ The use of this invention serveth for burning of the enemies shipps at what- soever appointed distance. ‘“ SECONDLIE, The invention and sure demonstration of another mirrour which receiving the dispersed beames of any materiall fier or flame yealdeth allsoe the former effect, and serveth for the like use. « THIRDLIE, The invention and visible demonstration of a piece of artillery, which, shott, passeth not linallie through the enemie, destroying onlie those that stand on the randon thereof, and fra them forth flying idly, as utheris do; but passeth superficially, ranging abrode within the whole appointed place, and not departing furth of the place till it hath executed his whole strength, by destroying those that be within the boundes of the said place. «“ The use hereof not onlie serveth greatlie against the armie of the enemy on * P, 354.

Biot, as an apology for the celibacy of Sir Isaac Newton, remarks, that when we consider how his time was occupied, we may easily conceive that he was never married. But we thus see that our philosopher who by this time was married to a second wife, and had six sons and six daughters, was just as completely and profoundly occupied with theology, science and the state of the country, as any human being could possibly be. Upon looking at the in- dorsation of this paper, it appears to have been received from some one of the * This very curious paper is little known, and no perfect copy of it has been hitherto printed. It appeared, but without any illustration, in Dr Anderson’s collection of fugitive pieces, entitled “ The Bee ;” in the month of June, 1791: but that copy is imperfect both in the contents and in the signature. It was reprinted with these errors in the year 1804, in the 18th volume of Tilloch’s Philosophical Magazine, where some of the inventions are illustrated with scientific re- search. The illustration, however, considered scientifically, is by no means complete ; but serves to show how much might be made of a review of Napier’s scantlings if thoroughly digested by a philosopher. Lord Buchan in his life of Napier, merely refers to the title of this paper, and calls it a “letter to Anthony Bacon ;” which shows he had not considered it. He refers his reader to his appendix for the document, where, thas it is not to be found. ‘creas In bef ~cithonary Vo V. foe Be.

England herself was threatened, and, accordingly, Napier frames his proposals in reference to the whole island. It was obviously not from this paper that Sir Thomas Urquhart obtained a knowledge of the machine he describes as having been put to a practical test in Scotland ; in that case he would have noticed the other inventions, and also the coincidence of Napier having offered to his countrymen a written sum- mary, or succinct description of more than one of the very schemes which Colonel Douglas presented to the states of Holland. We must therefore hold, that the knight of Cromarty is corroborated in his story by Napier himself, whose description of the third invention contained in his paper seems to agree precisely with that said to have been tried on a large plain in Scot- land. Whether the experiment actually took place, or with the effect al- leged, is, however, not of much consequence. Napier was as far removed as possible from the character of a quack, or empiric, in any branch of science to which he directed his powerful mind; and we may safely take it upon his own declaration, that he had mastered, so far as he was concerned, all the ma- chinery he describes. Neither is it necessary for his reputation in the matter that these inventions should be capable of the practical application which their author anticipated. That they are not so, or at least that their utility is super- seded by a more intellectual art of war, may indeed be taken for granted. But the question is, what evidence do they afford of Napier’s inventive powers when compared with the scientific resources of his day, and the scientific experiments of subsequent philosophers who illustrate more enlightened times? To answer this question properly, would require a profound acquaintance with science. If by laying the document itself in this authentic form before the public, a philosopher should be attracted to bestow upon it the illustration it me- rits, we shall have performed all that we can hope todo. There are, however, some readers who may be apt to regard with contempt these “ scantlings of inventions,” * as the shadows of a fanciful mind, or at best only worthy * In the year 1663, Edward Marquis of Worcester published what he entitled, “ A Century Ii . 250 THE LIFE OF of being classed with those visionary experiments of which we have an in- stance in the Italian alchemist who broke his bones in an attempt to fly. In the only scientific notice hitherto bestowed upon them, there is, from the nature of the publication which contains that notice, no attempt to trace the history of their origin in Napier’s mind, or to connect them with the state of the country and his own career. The reader of the Philosophical Ma- gazine is at once confronted with the Inventor of Logarithms, in a po- sition which, notwithstanding the scientific analysis, gives him, in that ab- stract consideration, something of the air of an over-excited philosopher, ex- ercising a fine mathematical genius within and upon the walls of a mad-house. But, having followed the progress of his mind, amid every collateral circum- stance likely to influence it, from his birth in the dawn of the Reformation, through his youthful studies so abhorrent of popery, to the maturer exertion of his faculties in the cause of God’s truth,—and then in its prominent part, even against those connected to him by the strongest ties, down to this year 1595-6, when the greatest excitement prevailed in the country from the ex- pected Spanish invasion,—the disagreeable effect of this luminous, but appa- rently isolated spot, vanishes in the natural union of the broad lights and sha- dows of his life, and we find the picture of a philosopher. Some remarkable coincidences, betwixt the mental structures of Napier and Newton, have been already noticed. ‘The remnant we are now considering will have suggested another very interesting parallel, viz. betwixt Napier and Archimedes,—the Newton of the schools of Greece. We may turn for a of the names and scantlings of such Inventions as at present I can call to mind to have tried and perfected, which (my former notes being lost) I have, at the instance of a powerful friend, en- deavoured now, in the year 1655, to set these down in such a way as may sufficiently instruct me to put any of them in practice.” A few of these are very analogous to Napier’s; but, with some brilliant exceptions, they are characterized rather by trick and plagiarism, than science and origi- nality. The following encomium may nevertheless be just: “ Here it may not be amiss to re- commend to the attention of every mechanic the little work entitled, a « Century of Inventions,’ by the Marquis of Worcester, which, on account of the seeming improbability of discovering many things mentioned therein, has been too much neglected; but when it is considered that some of the contrivances, apparently not the least abstruse, have by close application been found to answer all that the Marquis says of them, and that the first hint of that most powerful machine, the steam engine, is given in that work, it is unnecessary to enlarge on the utility of it.”— Trans. of the Society of Arts, Vol. iui. p. 6. 3 NAPIER OF MERCHISTON. 251 moment to the early epochs of philosophy, introduced to us by the revival of letters, when the mathematical stores of those illustrious schools were gra- dually unfolded by men worthy of that exciting task. “ In nothing, perhaps,” said one who deeply felt what he eulogized, “ is the inventive and elegant genius of the Greeks better exemplified than in their geometry. The elemen- tary truths of that science were connected by Euclid into one great chain, be- ginning from the axioms, and extending to the properties of the five regular solids, the whole digested into such clearness and precision, that no similar work of superior excellence has appeared, even in the present advanced state of mathematical science.” * Plato himself was one of the most expert geome- tricians of his time ; and how he regarded the science may be gathered from his reply to the question, In what manner Omnipotence is occupied? “ With geometry through all eternity,” said the philosopher, in allusion to the geo- metrical laws which pervade the physical universe. This was indeed a lofty conception and magnificent picture of the mixed mathematics, of which So- crates, too, offered a profound and practical view, even while he inculcated the propriety of its limitation, in mortal hands, to mortal necessities: ‘“ When we know,” said he, “ enough of geometry to measure our fields, enough of astronomy to measure our time, and to guide us by sea and land, we ought to affect no higher knowledge.” But, if we are to search for the most illus- trious instances of speculative and applicate science which the annals of the ancient world afford, we must study the works of Archimedes. He was born at Syracuse about 287 years before the Christian era; and his success in the higher geometry, independently of other mathematical attainments, is even now the wonder and admiration of an age of algebra. Geometry and me- chanics were the regions in which his genius delighted to expand; but so deeply was he imbued with the spirit of the pure and profound speculations of the former, that he seems to have disregarded, and is said in some measure to have disdained, his own most ingenious and effective mechanical inven- tions. Far in advance of his species, he carried his investigations on the most daring and determined wing of intellectual adventure, beyond the boun- daries of elementary geometry, to the most recondite fields of the higher curves, and the originality and fertility of his mind were manifested, not only by the most eminent success in these difficult and unexplored depart- ments, but by the germ which his methods of philosophizing disclosed of some * Professor Playfair’s Dissertation on the Progress of Mathematical and Physical Science, 252 THE LIFE OF of those subtile resources which constitute the power and the glory of the new geometry. His unwearied application to the properties of curves elicited the celebrated method of exhaustions, the most triumphant monument of his speculative genius, and one which bears much the same relation to the ancient geometry that the infinitesimal analysis does to the new. In the science of numbers, too, he was deeply versed; and the sands of the sea afforded a nu- merical subject commensurate with the magnitude of his mind. His well- known work, De Numero Arene, refutes, by a beautiful application of a logistic peculiar to himself, the plausible but crude proposition, that no mortal power of numbers would suffice to express the quantity of the grains of sand on the shores of the ocean. It was in this treatise that he evinced a know- ledge of that quantitative property lurking in the proportions betwixt arith- metical and geometrical progressions, which is the germ or fundamental prin- ciple of LOGARITHMS. With the aid of this, he supplied the deficiency of the arithmetical notation of the Greeks to express numbers unusually great ; but the glory was left for Napier to elicit from that numerical speculation a beam of light, still travelling with unchecked career in boundless space. To the Arenarius of Archimedes, therefore, we must recur in another chapter. With what finer genius of antiquity than him so justly called “ a man of stupendous sagacity, who laid the foundation of almost every discovery whose extension constitutes the triumph of our own age,” * could we compare the old Scottish baron, and how fearlessly may we do so! Though the schools of Greece be hallowed by such names as Euclid and Archimedes, and the last age of a brilliant but false philosophy, which succeeded the restoration of letters, saw the rise of Kepler and Galileo; still it may safely be said, that before the dawn of the Baconian era in Britain,—an era which Newton consum- mated, but to which Napier brought the first irresistible impulse,—the history of the mixed.mathematics is comparatively barren. We find, it is true, from the earliest times, rich treasures of speculative, and illustrious instances of practical genius; but where were the achievements of the new geometry, the celestial wing of physical astronomy, the fearless paths of navigation ! These accumulated triumphs are all crowded within the last two centuries, and belong to an island which in the preceding ages was a prey to savage tur- bulence, and seemed never destined to overtake, far less to outstrip the conti- * « Vir stupende sagacitalis qui prima fundamenta posuit inventionum feré omnium in quibus promovendis etas nostra gloriatur.”— Walls. NAPIER OF MERCHISTON. 253 nent in its immortal career of science and letters. In the conquests of the seventeenth century the Scotch philosopher stands first ; and we shall have to show that he was pre-eminently successful at the very point where the sage of Syracuse failed. But it will be no mean preliminary, if we can discover in- dications that Napier, on the other hand, could bend the bow of Archimedes. It is alleged that the Grecian philosopher considered the sublimity of abstract thought as debased by material contact ; but he did not act upon that selfish and mystical idea. No man, according to Livy and Plutarch, ever worked such wonders in and by means of mechanical science, as he did. “ Give me another spot for my foot, and I will displace the earth,” * was an expression scarcely hyperbolical in the mouth of a philosopher, whose achievements in statics rendered aghast the military experience of Rome. When the states of Sicily revolted, and joined the Carthaginians against the Commonwealth, Claudius Marcellus sat down before the rich city of Syracuse, which was expected to fall an easy prey to the vigour of the Roman arms. “ And so it would,” says Livy, “ but for one man in Sy- racuse; this was Archimedes, an unrivalled astronomer, but yet more ad- mirable for the invention and management of missile engines and other war- like contrivances, by which, with perfect ease, he rendered futile the most la- borious operations of the enemy. The wall of Syracuse, which was carried along the unequal surface of ridges, and thus in some places inaccessible, and in others almost so level as to afford an open path, he crowned with every species of engine, each adapted to the nature of its position. Marcellus placed his first class of ships against the fortification Achradina, whose bulwarks are washed by the sea; while with his archers, slingers and skirmishers, whose weapon it requires great skill to throw back again, he so plied the walls that nothing could live upon them. These, however, kept at some distance, in the smaller vessels, to afford room for their missiles. The other vessels were so disposed in pairs, closely wedged together by removing the banks of oars in the inside, as to be worked at one and the same time by the outside oars, and these sustained towers protected by a cover of planks, and other machines for shaking the walls. Against this armament Archimedes disposed machines of various ? * « This,” says Tzetzes, “ he uttered in his own Syracusian Doric;’ and then he gives the expressions thus, Tlé 60, nor Xagisiom rev yey xvgow wesc ; 254 THE LIFE OF magnitudes upon the walls. At the distant ships he cast rocks of a tremen- dous size, and those under the walls he pelted with lighter stones, of which, consequently, the showers were more frequently repeated ; and, besides all this, he hit upon a contrivance to annoy the enemy secretely and safely, by piercing the whole surface of the walls with loop-holes a cubit in length, through which the archers, and those who worked the light scorpions, darted their mis- siles,” &c. * The Roman historian proceeds to describe other machines of tremendous power, but enough has been quoted to display the analogy betwixt the pro- posals of Napier and what was actually effected by the patriotic science of Ar- chimedes, according to the accounts of Livy and Plutarch. But these histo- rians have said nothing of the celebrated burning mirrors which form so con- spicuous a part of the philosopher’s exploit upon that occasion ; and it is ob- vious that Napier must have found elsewhere the prototype of his catoptric in- struments which form his two leading propositions. Zonaras and Tzetzes, By- zantine authors, notice particularly the fact, that Archimedes destroyed the fleet of Marcellus by reflecting the sun’s rays upon it from a mirror, or mirrors of a particular construction. Tzetzes refers to a variety of authorities, and among the rest to Dion Cassius, and Diodorus Siculus ; but the passages he quotes have been lost, and we must now take the authority of those ancient authors upon that of the more modern. He also refers particularly to the Paradoxva Ma- chinamenta of Anthemius of Tralles, the celebrated architect and philosopher patronized by Justinian. A fragment of this Greek work is still preserved, in which the catoptric feat of Archimedes is much enlarged upon, andatheory of its execution given con amore ; but we cannot suppose that Napier derived any hint or assistance from this, which was only given to the world in the last century by the elaborate version of M. Dupuy.t It was most probably through Tzetzes that our own philosopher became acquainted with the fact, that the fleet of Marcellus was so destroyed at Syracuse; and unless we are to adopt the sup- position, that, by a most extraordinary coincidence, he hit upon the very schemes of Archimedes, and for the same patriotic purpose, without having studied his history or looking to him as a prototype, it is obvious that Napier had caught fire, to use an appropriate image, even at the feeble reflection which * Livit Histor.

NAPIER OF MERCHISTON. 255 Tzetzes affords, and actually succeeded in discovering the power which Archi- medes wielded. The fact itself, that in those rude and unlettered days of Scot- land, he could relish and emulate the triumphs of Archimedes, presents a re- markable picture of his mind, of which the interest is not a little heightened when we reflect, that, like the hero of Syracuse, it was for his country’s salva- tion he laboured ; and that, in adopting so noble an example, he must have felt himself ready to become her most prominent protector in the worst extremity. To what extent the proposals, which he then submitted to his country and to England, indicate the mental power which eighteen years afterwards gave the logarithms to the world, is a question which we can only expect to illus- trate in such a manner as may interest those to whom a popular view of the facts may be more agreeable than a profound exposition of the science. It is obvious that, in the preczs of his inventions, Napier intended to conceal rather than display the particular mode of his catoptrics, and the principles of the mechanism he had conceived. ‘This mystery was the fashion of his day, and we find that even in the greatest of his speculations, while benefiting the world by the result, he reserved to himself the secret construction of his canon, until the learned should inform him how they relished the invention. * But there can be no question, when we attend to that combination of power and unaffected simplicity which were the leading features of his mind, and which are so deeply impressed upon everything it produced, + that he had fully satisfied himself as to the inventions he thus vaguely intimated, that for years he had been occupied with the subject, and was now prepared, not merely with the mathematical demonstrations, but also with the practical proof, and visible demonstration of one and all of these warlike instruments, of which he ex- * « Promissum itaque mirificum Logarithmorum canonem habetis, ejusque amplissimum usum: “que si vobis eruditioribus grata fore ex rescriptis vestris intellexero, animus mihi addetur, ad ta- bule condendze methodum in lucem etiam proferendam.”—Canonis Descriptio, Lib. ii. C. vi. + Speaking of Napier’s great work, Professor Playfair observes, “ At a period when the nature of series, and when every other resource of which he could avail himself were so little known, his success argues a depth and originality of thought which, I am persuaded, have rarely been sur- passed.” Certainly no man was less indebted to extrinsic resources in every thing he undertook, than Napier. The first treatise extant on catoptrics is that attributed to Euclid; and which was only first published in Latin in 1604 by John Pena. Alhazen, the Arabian, composed a volume of optics about the year 1100, in which catoptrics are treated of. Vitello, a Polish writer, com- posed another about the year 1270. Most probably Napier never saw these works. 256 THE LIFE OF pressly claims to himself the envention. We may suppose that it was to these, among other projects of his fertile genius, that he so solemnly refers in his letter to James VI. in 1593; “ for let not your majesty doubt, but that there are within your realm (as well as in other countries) godly and good ingynes, versed and exercised in all manner of honest science, and godly discipline, who by your ma- jesty’s instigation might yield forth works and fruits worthy of memory, which otherwise, lacking some mighty Mzcenas to encourage them, may per- chance be buried with eternal silence.” And we may, perhaps, in this sentence trace an allusion to a work of his day which must have created some sensation in England. Leonard Digges, the grandfather of Sir Dudley, was an able ma- thematician, born in the county of Kent about the commencement of the sixteenth century. Exceedingly ingenious, and indefatigable in his attempts to apply the secrets of science to practical purposes, he published various works of the kind betwixt the years 1555 and 1570, when he died suddenly. One of his most cu- rious works he left unpublished. This was a geometrical treatise, entitled Pan- tometria, containing many rules for mensuration, particularly in the art of war, towards which his practical applications generally turned. His son, Thomas Digges, published this work in the year 1571, and dedicated it tothe Lord-Keeper, Sir Nicholace Bacon, among the papers of whose son, Anthony Bacon, Napier’s scantlings of inventionsarefound. In the twenty-first chapter of the first book of Digges’ Pantometria occurs the following passage :—“ But of these conclusions I mind not here more to entreate, having at large, ina volume by itself, opened the miraculous effects of perspective glasses ; and that not onely in matters of discoverie, but also by the sunne beames to fire powder or any other combustible mater, which Archimedes is recorded to have done at Syracuse in Sicilie when the Roman navie approached the town. Some have fondly surmised he did it with a portion of a section parabolicall, artificiallye made to reflect and unite the sunne beames a great distance off; and for the construction of this glasse, take great paines, with high curiosity, to unite large and many intricate de- monstrations ; but it is a mere fantasie, and utterlie impossible with any one glasse, whatsoever it be, to fire any thing onely one thousand pace off, no, though it were a hundred foote over. Marry true it is, the parabola for his small distance most perfectly doth unite beames, and most vehemently burneth of all other reflecting glasses. But how, by application of mo glasses, to ex- tend this unitie or concourse of beames in his full force, yea to augment and multiplie the same that the farder it is carried the more violently it shall pearse and burne, hoc opus, hic labor est, wherein, God sparing life, and the NAPIER OF MERCHISTON. 257 time with opportunitie serving, I minde to imparte with my countriemen some such secrets, as hath, I suppose, in this our age beene revealed to very few ; no lesse serving for the securitie and defence of our naturall countrey than surely to be mervailed at of strangers.” Thomas Digges, the editor of his father’s work, mentions, in his dedication to the Lord Keeper, that the author had intended to present it to Sir Nicholas, but was prevented by death; and he also declares in his address to the reader, that his father “ hath also sundrie times, by the sunne beames, fired powder and discharged ordinance half a-mile and more distante; which things I am the boulder to report, for that there are yet living diverse, of these his dooings, oculati testes,” &c.* It is not im- probable that Napier may have seen, or at least have been informed of the contents of this work, and that his own attempt to solve the important pro- blem of Archimedes may have derived an impulse from the alleged success of the English mathematician ; but by the year 1596 both Leonard and Thomas Digges were dead, and the catoptric secret of the former had not been dis- closed. The coincidence, however, serves to explain an expression in Napier’s leading proposition, which may be thought obscure and startling. He pro- fesses to be able to demonstrate “ their error who affirmeth this to be made a parabolic section.” To those not acquainted with mathematics and optics, this would convey no meaning whatever; while to those who are, it might, on a hasty consideration, seem to involve a blunder in catoptries or the science of re- flected light.+ It is difficult to give a distinct illustration of this matter, unless the reader have some knowledge of the geometry of curves, as well as of catop- trics, both of which are involved in the expressions to be considered. A cone may be cut through in a variety of directions, so that the outline of the cut surfaces will present a corresponding variety of mathematical figures. Some of these will be the circle and triangle, the well known figures of ordinary * Sir David Brewster (Edinburgh Encyclopzedia, Burning Instruments, ) has mentioned this work as published by the author himself, and that his son merely republished it in a second edition. But Thomas Digges says in his dedication, “ perusing also of late certaine volumes that he (Leonard) in his youthe time, long sithens had compiled in the English tongue, among others I found this geometricall practise which my father, if God had spared him life, minded to have presented your honor withall; but untimely death preventing his determination, I thought it my part to accom- plish the same,” &c. There are two editions of the work, 1571 and 1591. + I know from experience that scientific men are apt to consider this sentence as containing a hasty and erroneous proposition. Kk 258 THE LIFE OF geometry ; other sections, however, produce different curves, namely, the ellipsis, hyperbola, and parabola. The parabola is obtained by cutting the cone obliquely through one of its sides and the base, but always in a direction parallel to the opposite side of the cone from that which is cut. This curve, passing through the base, is obviously not complete in itself, and one of its cha- racteristics or properties is, that it has no tendency to complete a figure, like the ellipsis or the circle, by meeting or relapsing in a continuous line. A perpendicular line passing through the vertex of a parabola so as to divide it into two equal and similar parts is termed its avs; and within this axis is a point whose situation is geometrically ascertained, and which is termed the focus. The principles of conic sections are beautifully combined with optics in evolving the properties of burning mirrors, and the best form of their construction. If the polished surface of a mirror be concave and sphe- rical, it is a well known property, which can be geometrically demonstrated, that a ray of light falling upon it near and parallel to the axis, will be reflected at a distance from the mirror nearly equal to half the radius; this is the focus, where the condensation of the rays into a small space will be apt to pro- duce combustion. But it can be also geometrically demonstrated, that, in order to make the rays concur precisely in their reflection upon one focal point, it is necessary to give the concave surface of the mirror a parabolic curve, the pro- perty of which is, that every ray parallel to the axis of this parabola will be reflected precisely upon that point. Hence, if rays from the sun, or any ra- diating point so distant that the rays may be considered parallel to one ano- ther, fall upon the concave surface of a parabolic mirror, they will all be re- flected into its focus. Now, a hasty view of Napier’s proposition might lead us to infer that he meant to contradict what he considered a mistake in the catoptrics of his day, namely, that a parabolic speculum reflects the solar rays to the focus, as the burning point. But the mathematical investigation demonstrative of the truth of that proposition, is also sufficient to assure us that one so thoroughly master of geometrical laws as our philosopher could never have fallen intosuch an error. We must understand, therefore, his proposition in another sense ; and the pas- sage quoted from the Pantometria of Leonard Digges may assist us to the true meaning of Napier’s expressions, It appears, that, relying upon this known property of a parabolic speculum, various attempts had been made to construct a mirror of the sort, which would produce the astonishing effect of com- NAPIER OF MERCHISTON. 259 bustion at a distance far beyond the ordinary reach of any parabolic fo- cus.- Digges declared that it was a “fantasie and utterly impossible” to construct a mirror of the requisite dimensions for such a purpose, “ marry, true it is, the parabola for his small distance most perfectly doth unite beames, and most vehemently burneth of all other reflecting glasses :” What is this but the language of Napier, who, in proposing to burn the enemie’s ships “ at whatsoever appointed distance” also offers a demonstration of their error who affirm that this is to be done by means of constructing a mirror whose curve shall be a parabolic section; and the language of Montucla, in the eighteenth century, is precisely to the same effect; “ I] ne faut qwune légére théorie de catoprique pour appercevoir qu’ Archimede ne put produire cet effet par un seul miroir de courbure continue, soit sphérique, soit parabolique. La distance 4 laquelle devoient ¢tre les vaisseaux romains, n’eussent-ils été qu'un peu au- dela de la portée du trait, ou méme plus pres, auroit exigé une portion de sphére d’une prodigieuse grandeur ; car le foyer dun miroir sphérique est au quart du diamétre de la sphere dont-il fait partie. J] n’y auroit pas moins d’inconveniens dans un miroir parabolique: en vain proposeroit-on avec quel- ques-uns une combinaison de miroirs paraboliques, 4 Vaide de laquelle ils ont prétendu produire un foyer continu dans l’étendue dune ligne d'une grande longueur ; ce n’est-la qu une idée mal réfléchie, et dont ’exécution est imprac- ticable par bien des raisons.”* It was in consequence of such vain attempts, founded, however, upon a law of catoptrics undeniable in the abstract, that the exploit of Archimedes began to be looked upon as a fable ; an idea which, not- withstanding all the historical and scientific evidence in support of it, is even yet more or less entertained. If Napier, therefore, was conscious of having discovered the true secret, it was natural, that, to the announcement of that fact, he should add a proposed refutation of the practical error which had brought the attempt into disrepute. Scientific men might possibly take more profound views of his meaning, and discover some more original idea in his proposal, than that he meant merely to demonstrate the li- mited range of a practical parabolic focus. ‘The parallelism of the solar rays seems to be a postulate in arriving at the results of that form of specu- lum; and if we may suppose that Napier intended to change the direction of the solar rays from parallelism, and afterwards to bring them to a burning focus, certainly the parabolic figure would not have answered his purpose. * Hist. des Mathémat. T. i. -p. 232. 260 THE LIFE OF We shall not, however, presume to argue so refined a hypothesis, by which, in unskilful hands, our philosopher might haply be landed in a quirk, or even in a blunder worse than that alleged against him. That he had not fal- len into the mistake of denying the simple and well-established proposi- tion, that a parabolic speculum reflects the solar rays to a burning point which is the focus of the parabola, will be readily admitted by every man of science who compares the nature of that proposition with the genius of Napier ; and we cannot help thinking, that his true meaning is just as we have attempt- ed to illustrate it by the corresponding passages from Leonard Digges and Montucla. Napier flourished in a rude and credulous age, from whose hallucinations the loftiest intellectswere bynomeans exempt. As the wonders of natural magic became gradually developed, it is not surprising that the most extravagant hopes should have been formed of its practical application ; and that the beau- tiful phenomena, which could be actually demonstrated, were for a time mingled with the wildest theories, and the merest impossibilities. It was the age when theories were in their most gigantic growth, and philosophical experiments in the feeblest stage of infancy. But it would be exceedingly rash to class the catoptric propositions of our philosopher with such day-dreams, or even with his own astrological or rosicrucian propensities. Their value, as an evidence of his capabilities in profound and practical geometry, will be best seen by glancing at the history of such speculations since his own times. He probably soon became aware, that these scientific instruments were not likely to be of any service to the art of war, whose practical improve- ments really depend upon a combination of the greatest power with the most perfect simplicity and readiness of action. Consequently, his schemes shar- ed the fate of those which Archimedes was so fortunate as, upon one occa-~ sion, actually to perform,—they were cast aside, and fell into oblivion. There was still, however, among men of science, a hankering after the experiment, the principles of which fell continually under consideration during the pro- gress of optics. But, confined as these considerations generally were to the laws of ordinary reflection, the disciples of light, fascinated by their parabolic focus, kept gazing at that, and marvelling how a ship could get there, until they began to sneer at the immortal Archimedes and those who believed in him. At length the great DESCARTES arose, whose word was a law. The publication of his Dioptrics in 1637, established an era in the science of light. NAPIER OF MERCHISTON. 261 His investigation of the laws of refraction was, in one problem at least, emi- nently successful. Distinguished, however, for the truth and beauty of the geometrical demonstration, rather than for practicability, even the celebrated ovals of Descartes, (or those conic sections which he discovered to be the only form of a dens capable of concentrating incident rays to one focal point,) from the difficulties attending their construction, have also fallen into oblivion. But in the same work, that great man hazarded a very defective dictum on the subject of the -catoptrics of Archimedes. “ A burning mirror,” says he, “ whose diameter is not much more than a hundredth part of the distance betwixt it and the spot where the burning point ought to fall,—that is to say, whose diameter is in the same ratio to that distance as the diameter of the sun is to the distance betwixt it and us, though it were polished by the hand of an angel, would bring no more heat to the spot where it most powerfully concentrated the rays, than what would arise from the direct rays of the sun without the aid of such reflection; and this may be esteemed nearly equally true in the same proportion of burning glasses. Hence it is obvious, that. from a crude conception of optics, impossibilities have been imagined ; and that those famous burning mirrors of Archimedes, by which he is said to have con- sumed a fleet in the distance, must either have been mighty big, or, what is more probable, are a fabulous creation.” * If, as is possible, Descartes in this passage meant chiefly to deride their exertions who, assuming that Archimedes owed his success to the focal proper- ties of concave mirrors, toiled to construct the most perfect for that purpose, so far he only maintained that refutation which Napier proposed half a cen- tury before him. + But in limiting his remarks with the sceptical expressions * « Et speculum comburens, cujus diameter non multo major est centesima circiter parte dis- tantize que inter illum et locum in quo radios solis colligere debet ; id est, cnjus eadem sit ratio ad hance distantiam, que diametri solis ad eam que inter nos et solem, licet angeli manu expoliatur, non mag's calefaciet illum locum in quo radios quam maximé colliget, quam illi radii qui, ex nullo speculo reflexi, directé ex sole manant. Atque hoc etiam, feré eodem modo, de vitris comburenti- bus intelligi debet.

Vill. § xxii. + M. Dupuy, in his Commentary upon the Fragment of D’Anthemius, observes, in reference to the dictum of Descartes, “ Si Descartes n’a jamais parlé des miroirs plans, s'il n’a méme pas soupconné la maniére de les disposer pour porter l’incendie au loin, il est clair que ce n'est pas i cet égard qu'il a traité de fabuleux les miroirs dont on attribuoit Pusage au Géométre de Syra- 262 THE LIFE OF as to the exploit of Archimedes, Descartes betrays the fact, that profoundly versed as he was in optics, he had not discovered, what Napier had, namely, some other mode of operation, independent altogether of parabolic mirrors, which would afford the result required. At length, however, Athanasius Kircher, a man of an imaginative but most original and ingenious turn, laid a substantial foundation for refuting those who denied the possibility of the fact. In a work of his published nine years after the Cartesian Dioptrics, and entitled, “ Ars Magna Lucis et Umbre,” he pro- poses this question, “ Whether the mirrors of Archimedes and Proclus could set fire to ships at the distance described by some authors ?” He then reviews the ancient historians who have recorded the facts, and prefers the account of the Byzantine chronicler, Tzetzes, who calls the distance a bow-shot ; he also narrates, that, not satisfied with such vague statements of that important part of the problem, he went in person to Syracuse, examined minutely and critically that part of the walls anciently called Achradina, under which Marcellus placed his ships, and satisfied himself that the distance with which the philosopher had to contend was not more than thirty paces. Under these circumstances, Kircher seems to have considered it possible, that Archimedes may have had a concave mirror of such magnitude as to project a focus upon the ships; and that these might have been so steady under the walls, as to afford an oppor- tunity of applying that focus with effect. “ Nay,” says he, “ I admit that a mirror whose parabola would embrace a mountain, would throw a focus to a corresponding distance. But where is the man to construct a mirror of that portentous magnitude ? I myself, toiling to get to the bottom of this matter, have gone a pilgrimage through Germany, France, and Italy, to discover a parabolic speculum, the focus of which would reach the distance of twenty or thirty paces, and have found it not, even among the most cunning artificers.” He mentions, however, that his friend Manfredus Septalius actually succeed- ed in constructing one which burned at the distance of fifteen paces ; but the result of his researches and labours is the conviction, that human industry was unequal to construct a parabolic mirror with a focus beyond thirty paces. Kircher then betook himself to experiments with plain mirrors, cuse. Il en vouloit seulement a ce demi Savans en Optique, comme il s‘exprime, qui soutenoient qu’avec des miroirs concaves Archiméde avoit brilé des navires de fort loin ; d’ou il concludit avec raison que ces miroirs devoient etre extreémement grands, ou plutét qu’ils sont fabuleux.”—Z’Aca- demie des Inscriptions, 'T. xlii. p, 449. NAPIER OF MERCHISTON. 263 and professes to have solved the problem, “ How to construct a machine, com- posed of plain mirrors, capable of causing combustion at the distance of one hundred feet, or even further off.’ The extent to which he carried his prac- tical solution he declares to be this :—Having ascertained that a mirror of an ordinary size would illuminate a spot in the plain before it, diminished in the ratio of one-fourth to the reflecting mirror, and this a hundred feet off, he tried the experiment with a single mirror. This he found afforded a heat not equal to the direct heat of the sun ; doubling the reflection, by means of a se- cond mirror directed upon the same spot, he perceived a remarkable increase of heat ; a third mirror produced the heat of a fire; under the influence of a quadruple reflection, the heat was still bearable ; but, upon the application of a fifth mirror, the heat was scarcely to be endured. Satisfied with these une- quivocal results, Kircher proceeds no further, but recommends the extension of his experiment to future philosophers. * M. Dupuy, as an apology for the scepticism of Descartes, refers to the fact, that Kircher’s experiment was instituted nine years subsequent to the dioptrics of the former ; “and what geometrician,” he exclaims, “ before the time of Des- cartes, had ever dreamt that Archimedes might have operated by plain mir- rors? Kircher’s experiment is in truth the first of the kind since the days of Anthemius.” But, however limited Napier might have been in his practical resources, we owe it to his genius, and the boon he has bestowed upon mankind, to admit, when we read the summary of his inventions, that at all events through his abstract mathematical powers, he had arrived at the very result to which Kircher’s unwearied journeyings and practical labours had conducted him. It is even possible that he had instituted the experiment, as, indeed, Sir Thomas Urquhart’s relation would lead us to suppose he was in the habit of doing with all his inventions ; but if he had treated the problem pure- ly mathematically, as, on the other hand, some of his expressions seem to indi- cate, our admiration cannot be the less, when we find his abstract speculations, so subtile it would seem as to have escaped the catoptric penetration of Des- cartes himself in the succeeding century, completely verified by the experi- ments of Kircher. Napier, indeed, uses the expression of “ one mathematical point, in the which point most necessarily it engendereth fire ;” which might * Ars magna lucis et umbre in decem libros digesta.—Lib. x. pars iii., Magia Catoptrica. Kircher wrote many philosophical works ; he was not born at the date of Napier’s inventions, the year of his birth being 1601. 264 THE LIFE OF seem to exclude him from an experiment whose spot of combustion was one of very sensible dimensions. The expression, however, is natural to one who had solved the problem geometrically, and had ascertained the relative position of the burning point by mathematical laws; but that he did not even mean the concentrated focus of a parabola is apparent, as he expressly rejects that figure for his speculum. He mentions, indeed, not mirrors, but “a burning mirror ;” it is obvious, however, that he did not intend to be very explicit as to his machinery; and when he speaks of “ receiving dispersed beams of the sun,” and reflecting “ the same beams altogether united,” this, on the other hand, reminds us strongly of the reiterated reflections of Kircher. The latter, however, limited his experiment to the distance of a hundred feet; Napier proposed to burn “ the enemy’s ships at whatsoever appointed distance.” Hoc opus, hic labor est, as Leonard Digges well remarked when he proposed to make the focus burn more fiercely the further it was thrown. Our own philosopher’s proposal will be best illustrated by the experiment of one greatly distinguished in modern science. The Count de Buffon, led to the consideration not by studying the ancient historians, or from being acquainted with the fact of Napier’s proposals, or Kircher’s experiment; but because he was unwilling to bow like some of his friends before the shrine of Descartes ; set himself to construct mirrors capable of burning at the distance even of 300 feet. He was aware of the limited powers hitherto observed both in reflecting and refracting surfaces, and he at once perceived the practical difficulties in the way of constructing a mirror of sufficient demensions to cast a burning point 200 feet off. After many inge- nious experiments by which he ascertained the best reflecting substances, and also how much of the sun’s direct heat was lost by reflection, he arrived at the fact, that a large and a small mirror respectively produced, at great distances, an image of the solar rays not sensibly differing from each other except in temperature ; and always of a circular form, whatever might be the figure of the plain mirror. Reasoning mathematically upon these experiments he arrived at the con- clusion, “ que les courbes, de quelque espéce qu’elles soient, ne peuvent étre employées avec avantage pour briéler de loin, parce que le diamétre du foyer de toutes les courbes ne peut jamais ¢tre plus petit que la corde de Yare qui mesure un angle de 32 minutes, et que par conséquent, le miroir concave de plus parfait, donc le diamétre seroit egal a cette corde, ne feroit jamais le double de l’effet de ce miroir plan de méme surface: et si le diametre de ce 4 NAPIER OF MERCHISTON. 265 miroir courbe étoit plus petit que cette corde, il ne feroit guére plus d’effét qu'un miroir plan, de méme surface. Lorsque j’eus bien compris ce que je viens d’exposer, je me persuadai bientdt an’en pouvoir douter, gu’ Archimede navoit pu briler de loin qu avec des miroirs plans; car indépendamment de limpossibilité ou lon étoit alors, et ot Yon seroit encore aujourd’hui, d’ex- écuter des miroirs concaves d’un aussi long foyer, je sentis bien, que les réflex- ions que je viens de faire ne pouvoient pas avoir échappé 4 ce grand mathe- maticien.” Now, had-Napier written the sentence we have quoted, in refe- rence to his own catoptric proposition, which, like Buffon’s, was “ pour briler de loin,” we cannot conceive that he would not have been held to have per- formed his promise of “ an evident demonstration of their error who affirm this, [i. e. the burning mirror, ] to be made a parabolic section.” It would carry us too much into detail to give a minute description of the mirror, or combination of mirrors, which the laborious experiments and mathe- matical speculations of the Count de Buffon led him to construct. It is suf- ficient here to say, that he combined 168 portions of plain glass mirror (the di- mensions of each being six inches by eight) by fixing them in a frame, with intervals betwixt them to admit the free and independent motion of each in every direction, and, consequently, the application of their united reflections to the same spot. The machinery for this purpose was very complicated, but the result more than answered the philosopher’s most sanguine expectations. Some of these we cannot resist noticing, as they serve so well to sustain the simple truth of Napier’s concluding expressions, “ these inventions, by the grace of God, and work of expert craftsmen, I hope to perform ;” and to give something more of a philosophical character to that proposal than belongs to the vaunting dreams of Cardan or Bishop Wilkins. * The first experiment which Buffon made was upon the 23d of March 1747, at mid-day, when, having cast the united reflections of only forty of his glasses * Kircher (Magia Catoptrica) exposes the ill-digested and purely hypothetical proposal of Car- dan to cause combustion from the portion of a sphere at the distance of a thousand feet; and ex- claims, “ Good God, how much folly in a few words from one so learned withal.” But the fol- lowing out-Herods Herod. “By these mechanical contrivances it were easy to have made one of Sampson’s hairs that was shaved off, to have been of more strength than all of them when they were on; by the help of these arts it is possible (as I shall demonstrate) for any man to lift up the greatest oak by the roots with a straw, to pull it up with a hair, or to blow it up with his breath.” — The Mathematical and Philosophical Works of the Right Rev. John Witkins, late Lord Bishop of Chester, 1708.—p. 55. L | 266 THE LIFE OF upon a beech plank rubbed with pitch, at the distance of sixty-six feet he set it on fire, under disadvantageous circumstances. On the same day, having ad- justed his mirror more adroitly, he set fire to a plank rubbed with pitch and sulphur, by the application of ninety-eight glasses, at a distance of 126 feet. He made a third experiment in the following month, in the afternoon, when the sun was weak and the light pale, the result being a slight combustion pro- duced upon a plank covered with pieces of wool, from 112 glasses at the dis- tance of 138 feet. The following morning, when the sun was pale and cloudy, 154 glasses, at the distance of 150 feet, produced smoke from a pitch plank in less than two minutes; but the sun suddenly disappeared when the plank was on the point of flaming. His next experiment was at three o’clock in the af- ternoon, when the sun was yet more feeble; and upon this occasion, chips of fir-wood, rubbed with sulphur and mixed with charcoal, flamed in less than a minute and a-half, under 154 glasses, at the distance of 150 feet.* Many other experiments were all more or less successful; and the Count declares, that, with the same mirror, (for like Napier he speaks of a mirror, though it was composed of 168 separate reflectors,) under a summer sun and clear sky, he has set fire to wood at the distance of 200 and 210 feet, and was convinced that four such mirrors would be equally successful at the distance of 4.00 feet, and further. Again, we say, that had these very experiments been instituted by Napier in support of his own professions, it must have been admitted, that, “with the aid of expert craftsmen,” he had performed his promise to cause combustion, by united reflections, at a point mathematically determined in re- lation to the glasses used ; and this too “ at whatsoever appointed distance ;” for it is obvious that Buffon’s principles were capable of indefinite extension, at least within human means, which are necessarily finite. + * Sir David Brewster, in his article Burning Instruments, Edin. Encyclop. states this experiment as having been made at 250 feet, and that the effect was produced in two minutes and a-half. But M. Buffon in his paper says, “a 150 pieds de distance,” and, “en moins d’une minute et demie.” + We cannot refrain from quoting one other passage from the Count de Buffon’s paper, as in all its expressions it might have come from Napier as the theory of his first catoptric proposition. ‘‘ La théorie de mon miroir ne consiste donc pas, comme on I’a dit ici, 4 avoir trouvé l'art d’in- scrire aisément des plans dans une surface sphérique, et le moyen de changer a volonté la cour- bure de cette surface sphérique ; mais elle suppose cette remarque plus délicate, et que n’avoit ja- mais été faite, c’est quil y a presque autant d’avantage a se servir de miroirs plans que de miroirs de toute autre figure, dés qu’on veut briler 4 une certaine distance, et que la grandeur du miroir plan est déterminée par la grandeur de l'image a cette distance, en sorte qu’a la distance de 60 4 NAPIER OF MERCHISTON. 267 It was not, he tells us, until he was busy with his mirror, that he became ac- quainted with the precise details of Archimedes’ operations, as recorded by ancient writers ; and this was only in consequence of being presented with a classical dissertation on the subject by its author, and his friend, M. Melot.* What is yet more singular, it was only in this way that he became aware of the fact, that Kircher had turned his attention to the subject, and had suc- cessfully, though less perfectly, applied the very same principle. It is well for his fame in this matter that he was ignorant of Kircher’s works; as his own extension of the principle depended more upon expert craftsmen than any- thing else; but had he been thoroughly imbued with all that historians have written on the subject, from the marvellous Livy to the Byzantine Tzetzes, (which was all that Napier cow/d have had to assist him,) it would not have taken a leaf from his laurels, as their details are scarcely intelligible. The old authors who have mentioned the burning mirrors of Archimedes are, Lu- cian, Galien, Anthemius de Tralles, Eustathius, Tzetzes, and Zonaras. Of these, Anthemius alone is scientific. He lived about the end of the fifth cen- tury ; and it is curious to observe how completely his demonstrations agree with the experiments pursued by Kircher and Buffon. He supposes a hexa- gonal mirror, surrounded by other moveable mirrors of the same kind; to these he adds others indefinitely, and the more the better; and, by directing their united reflections to the same spot, proposes to effect combustion at a dis- tance. Napier, as already observed, could scarcely have seen this fragment ; but he may have read a passage of Tzetzes (who obviously derives his descrip- tion from Anthemius,) which has been much disputed.

Now the rays being reflected in it, a tremendous fiery conflagration arose in the ships; and, at the distance of a bow-shot, he re- duced them to ashes.” + This passage is so obscure, that it is not certain * Joannis Tzetze Historiarum, Chiliade II. vv. 118—127. + I have adopted the Greek version which Kircher adopts, and which gives the additional fact of the mirror being hexagonal. But a more popular reading is efaya» dvr, from e&dyw to bring out or produce. In that case, the translation would run thus :—“ The sage, bringing out the mirror which he had made.” M.

But the facts that Anthemius unques- tionably speaks of a hewagonal mirror, and that Tzetzes takes the description from him, appear to me decisive of the reading. The passage requires a comment, as modern savans of the first class are gradually corrupting it more and more. Montucla gives the passage, because, says he, it is remarkable in many respects ; but he only affords a rude Latin version, and does not attempt to translate that, which moreover he misquotes; for cvyuérgs in the third line, an important word, he gives commemorati, instead of commensuratt, or commensurata, which is the better ver- sion. Professor Peyrard translates the second line thus :—“ Le vieillard fit approcher un miroir heaagone,” &c. Sir David Brewster has it, “ The old man brought out a hexagonal mirror which he had made.” This is one way of conquering the difficulty, for they thus make the dubious words yield both conflicting meanings at once. NAPIER OF MERCHISTON. 269 whether the shape of the mirror be mentioned or not, and the expressions trans- lated “ both summer and winter,” and which probably indicate some relative positions betwixt the glass and the solar rays, have never obtained a satisfac- tory commentary. But we cannot doubt that the secret of Archimedes was just some modification of the plan which Anthemius and Kircher, and Buffon, all independently discovered; and that Napier, with equal originality, had done so before the year 1596. A translation of the works of Archimedes was executed by M. Peyrard in 1808 at the desire of the French Institute. That author added to his labours a very able paper demonstrative of his own improvements upon the burning mirror of Buffon. In this, which was formally reported upon and approved of by the Institute, the reader who wishes to follow out the subject will find very minute scientific details. We shall only quote Peyrard’s conclusion, which must exonerate Napier’s catoptric propositions from every charge of chimerical wildness, so long as the Institute of France shall be the throne of science. ‘ Nul doubte, du moins je le pense, qu’ avec 590 glaces de cing dé- cimétres de hauteur, on ne fat en état d’embraser et de reduire en cendres une flotte 4 un quart de lieve de distance; 4 une demi-lieue, avec 590 glaces d’un métre de hauteur, et 4 une lieue, avec 590 glaces de deux metres de hauteur.” * Our philosopher’s second invention, in the paper under consideration, it is not easy to illustrate. He professes to be able to produce the same astonish- ing results by means of reflection from any material fire or flame. This se- cret appears to be peculiarly his own, and to have died with him; for the nearest approach to it, that I can discover, is obviously very remote from the results he anticipated. Christianus Wolfius mentions in his Catoptrics, that an experiment had been made at Vienna to obtain combustion from a common fire, which had succeeded in this manner. ‘Two concave specula, composed of fine brass, the one six feet in diameter and the other three, were arranged at a distance from each other of twenty or twenty-four feet. A coal fire was placed in the focus of the larger mirror; and in the focus of the small one, a chafing- dish and candle with a sulphur wick. The reflected rays of the fire ignited the candle.t But this obviously affords very little support to the scheme of * T. ii. p. 486. 5 Experimento id comprobatum Vienne testo Zahnio, ope duorum speculorum concayorum ex lamina orichalcea confectorum.

It would, however, be exceedingly rash to pronounce a proposition of Napier’s, so positively and formally assert- ed, to be beyond the limits of science ; and the modern verification of his first proposition is an additional reason for treating his second with respect. We must recollect, that, from the state of science in his day, especially in Scot- land, he must have been chiefly indebted to the geometrical and algebraical powers of his own mind for the success of his speculations ; and those who have studied most deeply the steps by which he created the logarithms and un- fettered calculation, and who are best able to appreciate his celebrated trigono- metrical theorems, will know best how little danger there was of his being misled by such mental resources into the crude and visionary marvels, even of men so able as Cardan and Baptista Porta.* The latter ingenious author had, ten years after Napier’s birth, given perhaps the only remarkable impulse to optical science which it received since the labours of Roger Bacon, who, with all his devotion to the subject, had added little to those of Ptolemy and Alhazen. This last-mentioned philosopher, an Arabian who flourished in the eleventh century, was the successor of Ptolemy in optical discovery, though a thousand years divided them. He distinguished himself greatly by the ori- ginality and recondite nature of his geometrical applications to the rectilineal propagation of light, and in some respects excelled his master. Ptolemy, whose work on optics, however, was unknown in Napier’s day, connects immediate- ly with Euclid, who is supposed to have derived from the school of Plato the fundamental principles of optics, as regards the theory of direct light, and also filo sulphureo candelx circa apicem circumligatum. Radii carbonum reflexi candelam accende- bant.”—EHlementa Catoptrice, Chap. iv. p. 156. I have presumed that the 6 and 3 feet are the measure of the diameter of the specula, and not their focal distance. * Joh. Baptiste Porte Neapolitant, Magie Naturalis, libri viginti. Amstelodamt, 1664.— A curious work, full of scientific trifles. Itis in this work he describes his beautiful and popular invention of the Camera Obscura. Professor Playfair observes, “ He appears to have been a man of great ingenuity ; and though much of the Magiz Naturalis is directed to frivolous objects, it indicates a great familiarity with experiment and observation. It is remarkable that we find mention made in it of the reflection of cold by a speculum,—an experiment which of late has drawn so much attention, and has been supposed to be so entirely new. The cold was perceived by making the focus fall on the eye, which, in the absence of the thermometer, was perhaps the best measure of small variations of temperature.” Let no man hastily deride Napier’s second propo- sition. NAPIER OF MERCHISTON. 271 of catoptrics or reflected light, to which our philosopher’s propositions belong. The impulse which optics acquired from Kepler and Descartes was of a later date than Napier’s speculations. The third item of his secret inventions is clearly the warlike instrument described by Sir Thomas Urquhart; nor is there any thing more marvel- lous in the story than what might be made to appear from a covert description of many well known and successful efforts of mechanical genius. Coupling the anecdote in the Jewel with Napier’s own declaration, we have no doubt that he had constructed such a machine, and that it was actually tried in the neighbourhood of Edinburgh or Stirling. But some allowance must be made for the Knight of Cromarty’s peculiar vein, especially as he does not pretend to have been an eye-witness ; and that part of his story, therefore, may be doubted, wherein he declares the experiment to have been made “ to the de- struction of a great many head of cattle and flocks of sheep.” Our philoso- pher was too patriarchal to destroy his own flocks and herds,—too honest to kill his neighbours,—and too humane thus wantonly to massacre any of God’s creatures. We verily believe, that had he been placed with his secret artillery in the most convenient situation for scattering the “ Great Turc” and Antichrist himself to the four winds of Heaven, the machine would have received no im- pulse from his hand, though he might have hurled at the enemy the last sen- tence of his scriptural commentaries, “ O Rome! repent therefore always, in this thy latter breath, as thou lovest thine eternal salvation.” There is a tra- dition, that this “ 2fernal machine” of the sixteenth century was buried some- where in the neighbourhood of Gartness by order of the inventor himself, which agrees with the sentiment he is said to have expressed on his deathbed. It is curious to find the very sentiment echoed about a century afterwards, and under circumstances somewhat similar, by Sir Isaac Newton to one of the Gregories. ‘The name of Gregory will be remembered in Scotland until science is forgotten. Dr David Gregory of Kinnairdy, (ancestor of the celebrated Dr John Gregory,) among other philosophical attainments, was a most ingenious mechanic. Of him the anecdote is told by a relative of the family,* that * Dr Reid, nephew of Dr John Gregory.— See his Additions to the Life prefixed to his Uncle's Works, printed at Edinburgh, 1788. « Kinardie is above forty English miles north from Aberdeen, He (Dr David Gregory,) was a jest among the neighbouring gentlemen for his ignorance of what was doing about his own farm, but an oracle in matters of learning and philosophy.” This was very different from Napier, who, a7 2 ; THE LIFE OF “ about the beginning of the last century, he removed with his family to Aber- deen ; and, in the time of Queen Anne’s war, employed his thoughts upon an improvement in artillery, in order to make the shot of great guns more de- structive to the enemy ; and executed a model of the engine he had conceiv- ed. I have conversed with a clock-maker in Aberdeen who was employed in making this model; but having made many different pieces by direction, with- out knowing their intention, or how they were to be put together, he could give no account of the whole. After making some experiments with this model which satisfied him, the old gentleman was so sanguine in the hope of being useful to the allies in the war against France, that he set about pre- paring a field equipage, with a view to make acampaign in Flanders; and in the meantime sent his model to his son, the Savilian professor, that he might have his and Sir Isaac Newton’s opinion of it. His son shewed it to Newton without letting him know that his own father was the inventor. Sir Isaac was much displeased with it, saying, that, if it tended as much to the preser- vation of mankind as to their destruction, the inventor would have deserved a great reward; but, as it was contrived solely for destruction, and would soon be known by the enemy, he rather deserved to be punished ; and urged the professor very strongly to destroy it, and, if possible, to suppress the in- vention. It is probable the professor followed his advice; for at his death, which happened soon after, the model was not to be found.” The mechanical automata, both of ancient and modern days, have left nothing incredible in that department of science ; and when we turn from the artificial eagle and the iron fly of Regiomontanus, to the destructive mechanism of Napier, the latter appears, by comparison, a very humble effort. Nay, such is the universal reliance upon human powers in this respect, that Sir David Brewster, in a recent popular work, states, as a fact of which he expresses not the slightest doubt, that Janellus Turrianus of Cremona, who had for his pupil in such arts the Ex-Emperor Charles V., “ exhibited corn-mills so ex- ¢ there is good reason to believe, was an oracle in agricultural science as well as in mathematical. Dr Reid also mentions a fact with regard to David Gregory, which shows how well Napier must have managed matters to be the idol of his own Presbytery. “ He was the first man in that country (Aberdeenshire) who had a barometer.

They afford, however, a most interesting proof of the universal grasp of his genius. A machine is well defined, as being any thing that serves to aug- ment or to regulate moving powers, or any body destined to produce motion, so as to save either time or force ; and in their theory two principal problems present themselves: the first is to determine the proportion which the power and weight ought to have to each other, that they may just be in equilibrio ; the second is to determine what ought to be the proportion between the power and the weight, that a machine may produce the greatest effect in the given time. Now, we cannot conceive a mind like Napier’s to have been turned to this subject, and, as he himself says, successfully, without having deeply pondered and mastered these principles. But we must recollect that the very foundations of modern mechanical science were then hardly laid. About twenty years afterwards, Galileo was still busied with examining the strength and resistance of beams of different sizes and forms, and spe- culating on the motion of projectiles. “ Before the end of the sixteenth century,” says Professor Playfair, “ mechanical science had never gone be- yond the problems which treat of the equilibrium of bodies, and had been able to resolve these accurately only in the cases which can be easily reduced to the lever. Guido Ubaldi, an Italian mathematician, was among the first who attempted to go farther than Archimedes and the ancients had done in such inquiries. In a treatise which bears the date of 1577, he reduced the pulley to the lever; but with respect to the inclined plane, he continued in the same error with Pappus Alexandrinus, supposing that a certain force must be applied to sustain a body, even on a plane which has no inclination. Stevinus, an engineer of the Low Countries, is the first who can be said to have passed beyond the point at which the ancients had stopped, by deter- mining accurately the force necessary to sustain a body on a plane inclined at any angle to the horizon.” ‘“ The person who comes next in the history of mechanics made a great revolution in the physical sciences. Galileo was born at Pisa in the year 1564,” &e. * Letters on Natural Magic, addressed to Sir Walter Scott, by Sir David Brewster. 1832. P. 266. Mm 274 ; THE LIFE OF Thus both statics and dynamics were little understood at the time when our philosopher busied himself with inventions, depending so much upon a knowledge of the composition and resolution of forces; and although another destiny was in store for him than to create a new era in that department of science, we see that he was not incapable of having done so. The modesty of his nature, and the brevity which, as his son informs us, was peculiarly cha- racteristic of his style, entitle him to the credit of having studied mechanics far more extensively than he discloses in this paper; and his concluding expressions, “‘ besides devices of sailing under the water, with divers other devices and strata- gems,” may cover what Kircher or Baptista Portawould have swelled into a folio, The proposal of sacling under the water indicates a further extension of his mechanical speculations beyond the resources of his times. Archimedes had de- termined the weight of bodies immersed in fluids, and also the position of bodies floating on them; but the fundamental principle of modern hydrostatics, that the pressure of fluids is in proportion to their depth, was only laid by the work of Ste- vinus, which appeared not sooner than 1600. The diving-bell had not been in- vented; and our philosopher was here venturing into a region literally unexplor- ed, It is not improbable, considering the chemical propensities of the family, that Napier, besides the more ordinary contrivances for preserving respiration under water, had discovered a fluid, the effect of which was to restore corrupt air to a respirable state. ‘There seems to be no doubt that such a liquor had been obtained, through recondite chemical means, by a foreigner of the name of Cornelius Drebell, some years after the date of the Lambeth paper. This Dutchman was curious and ingenious in natural magic, but not at all averse to the reputation of originality in matters where he had not the right. The microscope, telescope, and thermometer, have all been ascribed to him upon grounds considered extremely equivocal. * It is not unlikely that the secret narrated in the following anecdote was just what Napier had discovered ; and if Drebell was one of those foreigners who originally came over to this country to look after the mines and minerals, the surmise would be still more plausible. The Honourable Robert Boyle, so distinguished in the annals of philosophy, mentions, in a work addressed to his nephew, Lord Dungarvan, “ A conceit of that deservedly famous mechanician and chymist, Cornelius Drebell, who, among other strange things that he performed, is affirmed, by more than a few credible persons, to have contrived, for the late learned King James, a * Montucla, Histoire des Mathematiques, Tom. ii. p. 237.

Now that for which I mention this story is, that, having had the curiosity and opportunity to make particular enquiries among the relations of Drebell, and especially of an ingenious physitian that marryed his daughter, concerning the grounds upon which he conceived it feasible to make men, un- accustomed, to continue so long under water without suffocation, or (as the lately mentioned person that went in the vessel affirmes) without inconve- nience,—I was answered, that Drebell conceived, that ’tis not the whole body of the air, but a certain quintessence (as chymists speake) or spirituous part of it, that makes it fit for respiration, which being spent, the remaining grosser body, or carcase (if I may so call it) of the air, is unable to cherish the vital flame residing in the heart; so that, (for ought I could gather,) besides the mechanicall contrivance of his vessell, he had a chymicall liquor, which he accounted the chiefe secret of his submarine navigation. For when from time to time he perceived that the finer and purer part of the air was consum- ed, or over-clogged by the respiration, and steames of those that went in his ship, he would, by unstoping a vessell full of this liquor, speedily restore to the troubled air such a proportion of vital parts, as would make it again for a good while fit for respiration, whether by dissipating or precipitating the grosser exhalations, or by some other intelligible way, I must not now stay to examine, contenting myself to add, that, having had the opportunity to do some service to those of his relations that were most intimate with him, and having made it my business to learne what this strange liquor might be, they constantly affirmed that Drebell would never disclose the liquor unto any, nor so much as tell the matter whereof he made it, to above one person, who him- self assured me what it was.” * There are not wanting other most interesting indications that Napier scarce- ly left any branch of science untouched,—that his gigantic mind applied itself to the Heavens and the earth, and the waters under the earth,—and that the mortal whom he emulated was ARCHIMEDES. ‘The spiral pump or screw which bears that philosopher’s name is universally known.

I have been much disappointed in not procuring a copy of this document, or a more perfect knowledge of its contents ; but the following information re- specting it was communicated by one who could not be misinformed as to its import :—“ This report contains a great deal of curious information which the Colonel had discovered, while investigating the subject in Scotland, upon the improvement which had been made by John Napier in the machine invent- ed by Archimedes, and known by the name of Archimedes’ Screw, for the purpose of raising water. It appears to the Colonel, that a statement of that invention had been carried out to India by some of the Portuguese, and had been adopted by the natives from the Portuguese who were established at Goa, and used in some parts of the peninsula of India for the practical purpose of irrigation. M‘Kenzie saw an instance of it, and was perfectly satisfied that the natives of India could not have adopted it from the original discovery of Archimedes, but must have adopted it after the improvement had been made by Merchiston, because the machine which he saw was not in the original, but in the improved form, as described in a paper which he had found in Scotland upon the death of the fifth Lord Napier, giving an account of different machines which had been made or improved upon by Merchiston.” § When the paper containing Napier’s schemes came into the hands of An- thony Bacon, Francis Bacon, his younger brother, had acquired none of his eminence political or philosophical, so its presence in that collection cannot be * That is to say, the water only rises in the screw in proportion to its descending power first applied. + CEuvres d’Archiméde, par F’.

It has generally been called “ a letter to Anthony Bacon ;” but I suspect it may be traced into his hands otherwise than by a direct commu- nication from the philosopher himself. In doing so, we must again recur to the connection betwixt our philosopher’s near relatives and the history of the times. Adam Bishop of Orkney died in the year 1593, and was buried beneath one of the pillars of the aisle of Holyrood, where his grave is yet shown to the curious stranger. We shall not say In Santa Croce’s holy precincts lie Ashes which make it holier. But, notwithstanding all the promises contained in the bishop’s letters, his il- lustrious nephew did not succeed to one farthing of his estate. Like Benedict, when he said he would die a bachelor the bishop did not expect to live to be married. He married, some time before the year 1571, a niece of the good Regent Mar, whose wife was the cousin-german of Sir Archibald Napier. The eldest son of this marriage was John Bothwell, who succeeded his father both in his seat on the bench, and in his abbacy. He became a great favourite with James VL., and inherited so little of his grandfather Francis Bothwell’s dislike to masking and mummery, that he was always ready to play the fool whenever his sovereign required him. In the year 1594, a few months after the philoso- pher’s letter of admonition to the king, the baptism of Prince Henry occurred, when his majesty entered the lists of the tournament, given upon that occa- sion, disguised as “a Christian ;” while Napier’s cousin, “the Abbot of Holy- roodhouse,” appeared at the same time as “ an Amazon in women’s attire, very sumptuously clad.” * By these and other courtly arts, John Bothwell stood high in the king’s favour, and rose to the peerage under the title of Lord Holy- roodhouse. + * « An exact Account of the Babtism of Henry Prince of Scotland, August 30, 1594.” + The following document, from the original in the Register-House, affords a curious picture of the footing upon which James was with his courtiers, and the manner in which he paid his debts :— « Rex.

The following original and unpublished let- ter is from the Lambeth Collection, and appears to have been received by An- thony Bacon about the time when he obtained Napier’s summary of secret in- ventions. “ A Tresnoble et vertueux Seigneur Monsieur Antoine Bacon, Esquier. “* Monsieur souventesfois m’est venu en l’entendement le service que je vous ay voué, mais n’ay eu jamais occasion de vous le tesmoigner jusques a present, esmeu par je scay quelle memoire de vos vertus, quide jour en jour prennent accroissement parmi les plus grands de ce pais, et souhaitent comme moy vostre bonne santé, le Roy m’en a souvent parlé, mais de cela il n’est propre a pre- sent d’escrire: Je feray tous les bons offices qui me seront possibles encore qu'il n’y en ait point de besoing.

He spent many years of his youth abroad, and was much at Bourdeaux, where he met John Bothwell. He returned to settle in his own country about the year 1591, and attached himself with the most enthusiastic devotion to the service and friendship of Robert Devereux Earl of Essex, the lover, the hero, and the martyr of Queen Elizabeth. Anthony Bacon’s volumi- nous papers and correspondence are reposited in the library at Lambeth Palace, and from these it is evident that the secretary of state himself was scarcely more engrossed with public affairs, or more generally regarded in state nego- ciations than he was, at the period when our philosopher’s schemes for de- stroying the enemy came into his hands. ‘These must have been submitted to him, (perhaps by Sir William Stewart, or by the relative whom John Bothwell mentions in his letter,) not simply on account of their scientific curiosity. When we compare the dates of that paper with those of public events at the time, the fact is very naturally accounted for, that one so unassuming as our philosopher should have offered to the whole island his Archimedean powers, and have afterwards cast them aside, and even refused to give them further publicity. The moment was one of great excitement in both countries, and that excitement arose from the very circumstances which for years had en- grossed the mind of Napier, even in the midst of his scientific speculations ; * Lambeth MS, Bacon’s Coll. vy. fol. 116. orig. I am also indebted to the liberality of His Grace the Archbishop of Canterbury for this letter, which is not in Birch’s Collection. It is in- dorsed “ Domini Bothwell ou Holirudhouse, le 6me d’Aoust, 1596.” Bothwell was not a peer at this time, and his signature must have been as commendator of the Abbey. He was raised to the peerage, with that title, by charter dated at Whitehall 20th December 1607. 280 THE LIFE OF namely, the treasonable intrigues of the popish nobility with the King of Spain, * The state of affairs in Scotland at this time, was written in a letter from Edinburgh on the 23d of November 1596, to this purpose: The ministers were in a continual uproar, clamouring against the king and counsellors for the liberty allowed to the excommunicated earls, having shown the king a copy of a respite granted to those lords, to remain for the space of six months in the country, peaceably, unmolested by any man. This respite was subscrib- ed by his majesty, the Duke of Lennox, the Earl of Mar, the Earl of Athol, the Treasurer, President, Mr John Lindsay, and all the rest of the council. But every one of them denied it.”* Anthony Bacon’s feelings on the state of the times seem to have been congenial with those of Napier. In the very month when the latter drew up his warlike propositions, Bacon begins a letter to his mother, with a pious reflection on the weather, which had been at Lon- don extremely stormy and unkindly for the season, “ the changes whereof,” says he, “ as they were used for threatnings by the prophets in antient time, so God grant they may work now in us as due and timely apprehension of God’s heavy judgement imminent over us for the deep profane security that reigneth too much amongst us.” He then, (adds Birch) informs her ladyship, that an account arrived at court the day before, that the French King and King of Spain, by the entremise of a Florentine cardinal sent into France from the Pope, had made a truce for three months, and that the Grand Signor was for certain on horseback himself, with two hundred thousand men, and likely to be a heavy scourge to Christendom. Napier’s paper, dated on the 7th of June 1596, seems to have been de- livered to Bacon in July following. On the Ist of June of that year, the celebrated expedition against Cadiz, in which England acquired so much glory, set sail; the land forces being commanded by Essex, and the fleet by = “ Memoirs of the reign of Queen Elizabeth, from the year 1581 till her death ; in which the secret intrigues of her court, and the conduct of her favourite, Robert Earl of Essex, both at home and abroad, are particularly illustrated from the original papers of his intimate friend An- thony Bacon, Esquire, and other manuscripts never before published.

I find, what I was not aware of when the previous sheets went to press, that Dr Birch has ~ not omitted, in his collections from the Lambeth papers, Napier’s scantlings of inventions; of which, however, his transcript is faulty and imperfect. This, probably, is the source from which it found its way into Tilloch’s Philosophical egg NAPIER OF MERCHISTON. 281 the Lord High Admiral, Howard. Most probably Napier’s schemes were transmitted to the bosom friend of Essex in reference to this very expedition, the result of which, however, proved how independent Old England was of catop- trics as a means of destroying the enemy’s fleet.* With no mirrors but those mirrors of Knighthood, Effingham, Essex, and Raleigh, “ Her Majesty de- feated and destroyed the best fleet which the King of Spain had together in any place, and amongst those his ships of greatest fame, and in which all the pride and confidence of the Spaniards were reposed. The captains of them confessed, aboard the Due Repulse, that forty gallies were not able to encounter one of her Majesty’s ships.” + * In like manner, when, in the year 1833, the lineal descendant of our philosopher, Charles Napier, Viscount Cape St Vincent, annihilated the whole naval force of the King of Portugal,—by an action as brilliant in the annals of British prowess as the cause it illustrates is mean in political history,—he preferred boarding to burning glasses. + “ A paper, entitled the Advantages which her Majesty hath gotten by that which hath passed at Cadiz the 21 of June 1596.”—Lambeth Coll., Vol. xi. fol. 146. 282 THE LIFE OF CHAPTER VII. It may be imagined, that after so long a succession of wars and civil com- motions, the agriculture of Scotland was at its lowest ebb, and the people reduced to famine. A contemporary chronicle records, that, “ during all this yeir (1595) thair was great scant of cornes, and exceiding great derth. The somer was sa raynie, that the maist part of the cornes war rottin on the grunde before that thay war cut doun, and the rest that was cut doun spilt for fault of dry weather. Thair was also a great decay of the bestiall, and manie poor people deit for hungar, and sum of better estait had na better con- ditioun ; for thay war constraynit to sell the best of thair geir to supplie the gredeynes of mercats.”* It is remarkable that the first impulse to agricultu- ral activity emanated, while the country was in this state, from the family of Merchiston. Archibald Napier, the philosopher’s eldest son by his first marriage, was educated at the University of Glasgow, which he entered in March 1593. Instead of going abroad after finishing his studies there, he returned home, and became almost immediately attached to the household and person of James VI. “ Had I ten sons,” exclaimed the famous Scaliger, “ not one of them should be scholars, I would make courtiers of them all;”+ and such seems to have been the plan adopted by John Napier with regard to his first-born, who tells us himself, “ After I had left the schooles, I ad- dressed myself to the service of King James of blessed memory, and wes gra- tiously receaved by him; and after the death of Queene Elisabeth, I follow- ed his majestie into England, when he went to receave the crowne of that * Historie of James Sext. + “ Sij’avois dix enfans, jen’en ferois estudier pas un, je les avancerois aux cours des princes,” —WScaligerana. 4 NAPIER OF MERCHISTON. 283 kingdome.” * It seems, however, that, in the short interval betwixt his leav- ing college and becoming a courtier, young Napier had so far attended to agricultural matters, as to entitle him to receive the royal gift of a monopoly of a new mode of tillage, which, most. probably, the experience of his father or grandfather had discovered. On the 23d October 1598, there is noted in Birrel’s Diary, “ Ane proclamatione of the Laird of Merkiston, that he tuik upon hand to make the land mair profitable nor it wes befoir, be the sawing of salt upon it.” And in the register of the privy-seal appears a grant from King James to “ Archbald Naper, apperand of Merchistoun,” as one qualified and expert in such matters, of a monopoly of this new mode of tillage for twenty-one years. At the same time there was published, “ The new order of gooding and manuring of all sorts of field land with common salts, whereby the same may bring forth in more abundance, both of grass and corn of all sorts, and far cheaper than by the common way of dunging used heretofore in Scotland. Set forth by Archibald Napier, the apparent of Merchistoun, con- form to the gift of office given him by the king’s majesty under the privy-seal, with advice of the Lords of Council thereof, and made to him thereanent, of the date at Holyroodhouse the 22d of June 1598 years.” +} We suspect, how- * < A true relation of the injust persute against the Lord Napier, written by himselfe.”— MS. in the handwriting of the first Lord Napier.

THE LIFE OF ever, that young Napier’s share in this agricultural discovery must have been very small, though the profits were presented to him, probably, to fit him out in the commencement of his courtly career. He could not have acquired suffi- cient experience in such matters, aud he takes no credit to himself for it in the autobiography he has left. The plan must have undoubtedly ori- ginated with his father or grandfather; and, considering the charge the philosopher took of country matters, it is not unlikely that the merit of it chiefly belongs to him. Certainly he cannot be said to have afforded, like David Gregory, any merriment to the neighbouring gentry from that ignorance of farming operations, which, however, would have been excuseable in one deeply immersed in abstract mathematical speculations ; and we have no doubt, that, wasted as were the fields round Merchiston during the civil wars, they presented, in those desolate years to which we have brought down the family history, the fairest prospect and the best example in the Lothians. The pub- lished account of the Merchiston mode of tillage is too rare and curious to omit. It contrasts finely with the scenes through which we have traced our philosopher ; and, compared with his warlike inventions, and the anecdote of his too successful experiment of destructive ingenuity, is placid and warm as Cuyp beside the stormy Borgognone. “ After the corns are win and put into the barn-yard, the piece land tilled, and the wheat seed ended, you shall till down the land whereon you intend to sow down your bear seed ; and if the same be clay, or reasonable stiff, and not sandy land, you shall sow on every acre red land thereof one boll of com- mon salt ; and if it be sandy ground, one half boll will suffice. Do that upon even and level ground, so soon as you can before every Martinmas, so that the land may have sufficient time to rot and digest the said salt' in the winter season, that the salt may temper; make the land moury and soft, and open the same before it be sown with any sort of seed; for the nature of earth being cold, and the nature of the salt being hot, will, with temperate mois- that they, nor nane of them, of whatsumevir estate, qualitie, or condition thay be of, presume, nor tak upoun hand to use, hant, or frequent the foirsaid novation of guiding, mukking, or manuring of thair landis, ather manurit or pasturage, during the said haill space, certefeing thame that dois in the contrair, that they sal be constraint to content and pay to the said Archbald the soume of [ten shillings] for everie aiker tharof that thai sall manure efter that sort and maner, alsweill corne land and pasturage, during the space foirsaid.”—Privy Seal, 70. 22 June 1598. NAPIER OF MERCHISTON 285 ture, in summer with heat, accordingly bring forth, God willing, plenty of bear and clean, without weeds. You must in due time till the said land over again once, or in some places twice, very near before the time you should sow your bear-seed, according to your common use of two or three furrows for the most part of our country. But if your land lie hanging or dipping down, you may before Martinmas sow the said salt upon the stubble-land, where you would make your bear; but immediately till the same down, lest the substance of the salt descend over soon from the land by the great showers in winter ; and in due time before you sow, you must till the said land once or twice again, according to your custom of bear-land, or as the stiffness of the ground re- quires, for sandy land needs but twice tilling. “When you have sown your white seed, you may sow for every boll of wheat, upon reasonable stiff or clay-land, one half boll of salt thereupon, and in sandy ground one firlot of salt; and let all be harrowed together, and hereby, God willing, you may have a good clean crop. In like manner, when you have sown your oat-seed, you may sow three firlots of salt upon every boll of oats sowing ; but this must be done upon watery or laigh land only, as upon meadow or haugh land, whereupon the water stands commonly in winter, ye shall, God willing, find a rich crop. But upon dry ground ye shall sow no salt when the oat-seed is presently sown, but before Martinmas, ex- cept with wheat, as said is, else you shall rather lose as gain. You shall sow no salt with bear instantly, neither upon wet nor dry ground ; but as long be- fore Martinmas as you may, as said is. “ The general rule of salt is, that the same be sown on all sort of land four or five months’ space before the same be sown with any seed, and that accord- ing to the quantity above specified, more or less, as you shall find by expe- rience your sort of ground may bear. For it is certain, if over much of com- mon dung be laid upon land, or yet over little, [there will be little] or no in- crease of corn. The like happens in salt, and, therefore, I refer you to expe- rience, and the above quantities. ** Follows the order of pasturage, and to increase the grass, both in abundance and goodness, which being rightly used, may enrich our countrymen wonder- fully.

Make your parks so near the one to the other, that upon the said Whitsunday, when your cattle or bestial have eaten the grass of the first park, upon the morrow they may go to the second, and eat in the same; and the third day to eat and pasture in the third, and so forth, till they have eaten the twelfth park; and then to return and eat in the first park, it being cleansed and salted as hereafter. * The said Whitsunday, which is the first day that you enter and eat the first park, you shall let the cattle feed and pasture themselves until eleven o’clock that you give them water to drink, and thereafter put them into a common fold till two afternoon to dung the same, as use is; and at the said two hours, put them again into the said first park to pasture themselves until eight o’clock at night; then take them forth to drink, and thereafter all night put them to dung in the said common fold; and let them never tarry over night in the said parks. “ When the herd hath folded the cattle at eight hours after even for the night time, he must return to the first park where they eat all the day, and there with a sharp shovel must take up the dung of every cow or ox, and throw it out of the park in a maund or scull ; and upon every place where the said dung lay he must sprinkle a little salt, or some earth and some salt sprinkled thereupon, or some salt-pickled water, otherwise the cattle will not eat the grass that grows thereupon where the dung lay ; where [as] if salt be put thereupon, they will rather eat that grass than any other. “ When they come about again to the thirteenth day, eat again in the first park; and as the herd has done the first day to the first park, see that he do the same the second day to the second park; and that he fail not to do the same every night as a good servant; and so on the third day to the third park, and so forth till all be eaten, and that they return to the first park. One acre used this way will feed twice as many cattle as otherwise; and the kine fed NAPIER OF MERCHISTON. 237 thereon will yield twice as much milk as they that are fed on unsalted grass. Every year thereafter, for the space of five years, the said parks will fold more cattle, and they be better fed ; and then, if you please to till and sow the said parks for the space of four years thereafter, there will more corn and bear grow than may in a manner stand thereupon. Let the dikes stand notwith- standing the tilling thereof. “ If the use of salt come up this way among us, I doubt not but all men will request his majesty that no man be allowed to transport salt out of the kingdom ; whereunto I most earnestly entreat you all to practise the discharge of the same. | “ That no man take upon him to use this kind of husbandry without licence from the said Archibald, or his deputies, under the pain of ten shillings to be paid him for every acre of land they labour therewith, as well grass as corn, conform to his gift granted thereupon by his majesty.” * We thus see, that with whatever romance the scientific powers of our phi- losopher, and the members of his gifted family, may have been seasoned, those powers were not lost in the mazes of superstition, nor did they evaporate in vain attempts to work by magnetic sympathies, or to discover the secrets of Hermes. “ The King of Tunis, invaded by a powerful enemy, promised toa neighbour who assisted him, the philosopher’s stone. He sent a plough, terming it the philosopher’s stone, because it would produce rich crops, to procure gold in plenty ;”+ and the secret, which Merchiston thus ably com- municated to the country, might have done more than the immortal elixir for Scotland, by infusing a spirit of practical improvement, and new agricul- * Archaelogia Scotica, or Transactions of the Society of Antiquaries of Scotland, Vol. ii. p. 154, <“ This curious paper is given from a MS. in the Archives of the society, which appears to have been taken from the printed copy [printed by Robert Waldgrave, printer to his Majesty ].

When we consider the glad tidings brought to human knowledge by the promul- gation of logarithms a few years afterwards, it is doubly interesting to con- template the fitful rays which from time to time were shooting from the rude tower of Merchiston, across the whole horizon of the arts and sciences. Nearly two centuries and a-half have passed away since this agricultural es- say was composed in the midst of the darkest ignorance and distress pervading Scotland. Yet, both in the practical knowledge it displays, and in the style of composition by which it imparts that knowledge, we would even now fearlessly submit it to the most hypercritical consideration of an age rejoicing in a Board of Agriculture. The application of common salt to this important purpose was a discovery by no means obvious, or one easy to practise when discovered. Upon a cursory investigation of its properties it is apt to be rejected, or, at least, to be used so sparingly as not to afford very strikingor extensive benefit; and it was not without reason that Merchiston laid down such special rules for the ma- nagement of his system. Lord Kames, in his “ attempt to improve agricul- ture by subjecting it to the test of rational principles,” observes, “ Salt is powerful ; and an overdose of it does more mischief than of any other manure. It is soluble in water, and by that means enters the mouths of plants. Its effects, the, must be the same with that of lime-water ; and, considering how sparingly it ought to be laid on land, it is not obvious what other effect it can have.”* Now we will venture to say, that the Merchiston method was found- ed upon a deeper knowledge of the experiment than this; and that had his Lordship read the tract of 1598, he would have paused longer upon the sub- ject. Since his time, experiments have been instituted which go to prove, not that such a system is futile and founded on unscientific principles, but that it is one requiring extensive practical knowledge in the management, and which even now demands a more thorough investigation. This will appear from the following observations contained in a work published under the auspices of one who deserves to be called the Genius of Scottish agriculture. “ Much has been said as to the utility of salt as a manure; but many doubts are still entertained on this subject by respectable agriculturists. From its well known antiseptic quality, it would at first sight appear not a very * The Gentleman Farmer, &c. by the Honourable Henry Home, Lord Kames, one of the Se- nators of the College of Justice.

Indeed, the most generally received opinion, among those who recommend it as a manure, seems to be, that it serves vegetables in the same way it does animals, 2. e. ra- ther as a condiment or promoter of digestion than as affording them nourish- ment from its own substance. Numerous experiments have been made to as- certain its effects as a manure, but few of them have been productive of favourable results, and of these few the generality seems only to place it among manures of an inferior class. In one case, however, its effects appear to have been eminently conspicuous. The case here alluded to is a series of experi- ments made by the Rev. Dr Cartwright, for which he obtained the gold medal from the Board of Agriculture. Having laid out twenty-five lots or beds, forty yards long and one broad, he planted each of them with a single row of potatoes after manuring them all differently ; and, after carefully and accu- rately stating the different appearances in all the different stages, and placing in regular succession each lot, with its produce in weight opposite, he found the preference due to a mixture of salt and soot, while plain salt occupied the sixth place; so that in this instance there were no fewer than nineteen manures inferior to it in the scale of public utility ; and in that list were malt dust, fresh dung, and lime. ¢ venerem quo- que asserat, sic qui pisces horoscopi initium dicit octave domus dominam, atque ego martem octave imperare, nonne videtur tibi, ex tanta diversitate diversum judicium oriri debere?

Now, as he appears to have a way of his own, it would be exceedingly rash in me to pronounce or predict any thing there- upon regarding the fate of your little son. But suppose I am deceived, and that he really follows Alcabitius, still, as Alcabitius differs from Regio- montanus, were I to give judgement here it might be inconsistent with what I have already given, and thus lead me to contradict myself. I therefore re- turn the nativity untouched, however mindful of my duty and your kindnesses, which would impel me to undertake much greater difficulties for your sake.” He then adds what he calls a sufficiently familiar example, to convince his Lord- ship of the contradiction that might arise from the contrariety of methods, and, as an excuse for not pronouncing a second judgment, which might haply afford the profane a scoff both against himself and the “ ever-to-be-venerated art.” The letter in the Merchiston charter-chest is probably an old copy taken at the time. The address might mean either Lothian or Loudoun. But Lord Lauriston died in the year 1629, and Sir John Campbell of Lawers, first Earl of Loudoun, did not obtain the patent of his earldom until some years after that date. The letter must have been addressed, therefore, to an Ear] of Lothian, and probably it was to John Napier’s class-fellow, Mark Ker, commendator of Newbottle, who became first Earl of Lothian by patent in 1606. The family dispute (which gave rise to the only harsh expressions ever breathed against our philosopher, and those unjustly,) terminated before the Oth of June 1613, on which day he was served and retoured heir of his fa- ther in the lands of Over-Merchiston. That he had dissipated his means by his inventions is an assertion characteristic of the inaccuracy of Dempster.* During his father’s lifetime, he was infeft in the extensive barony of Nether Merchiston in the Lothians, including the pultrelandis and their hereditary office. Also in the lands and miln of Gartness, the lands of Dolnare, Blareoure, Gartharne, the two Bollatis, Douchlass, Badwow, Edinballe, Ballacharne, and Thomdaroch, with the forests and woods thereof, and the fishings in the waters of Anerick and Altquhore, situated in the earldom of Levenax and shire * The work to which Dr M‘Crie refers is, Historia Ecclestastica Glentis Scotorum, by Tho- mas Dempster; a man of great learning, but not to be trusted as an authority for facts. NAPIER OF MERCHISTON. 323 of Stirling ; also the fourth part of the fishing of Loch Lomond ; also the half of the land of Ardewnane, with the right of patronage of the church thereof, with the fishing of Loch Tay, within the lordship of Discher and Toyer in Perth- shire. In the Menteith, he was infeft in half the lands of Rusky, half the lands of Thom, the three Lanarkynnis, Cowlach, Sauchinthom, the miln of Lanark, the lochs and fishings of all the said lands, the third of the lands of Cailzemuck, and the fishings on the Water of Teith, and loch of Gudy. All the above estates in the Levenax and the Menteith, composed the barony of Edinbelly. But he was likewise infeft in the lands of Blairnavadis, and the island of Inchmone of Loch Lomond; also in the lands and miln of Achinleschy ; also in the lands of Boquhople, which last were disponed to him the year be- fore his death, by Archibald Edmonstone of Balintone, whose daughter, pro- bably, it was to whom his murdered brother had been married. Besides all this, his father acquired the estate of Lauriston, and had high emoluments from his office. To have dissipated such means, John Napier must have “ played the ryot” indeed. These estates all descended, improved and undimi- nished, to his posterity, except that he sold the pultrelands and office of king’s poulterer to Nisbet of Dean, in the year 1610, for one thousand seven hundred marks. With the exception of those little episodes we have noticed, of battle, mur- der, and sudden death, Popish plots, pestilence, and famine, ever and anon demanding more or less of our philosopher’s time and attention ; together with the whole charge of his own twelve children, and more than half the charge of his unruly brothers, besides farming operations, extending from the shores of the Forth to the banks of the Teith, and the islands on Lochlomond ; mingled with occasional demands upon his “ singular judgement,” from the General Assembly of the church, to the dark outlaw who indulged in magic, and the courtly lawyer who sought a lesson in mensuration ; with the excep- tion, we say, of these inevitable interruptions, our philosopher lived the life of an intellectual hermit, entirely devoted to his theological and mathematical speculations, and delighting in no converse so much as the clear crow of his favourite bird, more powerful to “ dismiss the demons” than all the incanta- tions of Lilly. Betwixt the years 1593 and 1611 his mind was divided betwixt his great theological work, which he considered to be yet only in embryo, and the con- 324 THE LIFE OF fident hopes he cherished of being able to emancipate science, now in manifest danger of being strangled by the increasing coils of calculation. Still, however, the progress of religion was his chief object. The Plain Discovery had found its way into every Christian country, and Napier had paused eighteen years for the judgment of the Protestant brethren, and the reply of a Catholic cham- pion, as preparatory to publishing his Latin commentaries. He had the sa- tisfaction in that time to find his work received with growing admiration by the well-affected and regarded at least with respect by the adversary. But the former expressed doubts upon some controversial points, and the latter threatened to give battle to it all; and the consequence was, that, at the end of that long period of probation, Napier still delayed his Latin folio. He publish- ed, however, in 1611, a new edition of the Plain Discovery, and added what he entitled, “a resolution of certain doubts proponed by the well-affected brethren, and needful to be explained in this treatise.” The sentence with which he in- troduces this additional treatise is characteristic of his gentle dispositions, and shows how much he must have been harassed, and how little he could have been to blame in the contention with his brothers. “ As,” says he, “ we are commanded by the Spirit of God to separate ourselves from all disputers con- tentiously by strife of words, (1. Tim. vi. 4, 5.) so are we bound and com- manded, with gentleness and meekness to instruct all that are doubtful minded, that they may know the truth. (2. Tim. ii. 23, 24, 25, 26.) And seeing there are certain well-affected brethren, who, not in the spirit of arrogance and con- tention, but in all sobriety and meekness, have craved of me the resolution of some doubts arising upon my treatise of the Revelation; therefore, discharg- ing my duty, I have thought good to write a resolution of their doubts, and to insert the same in this treatise upon the Revelation, for the better satisfac- tion of their reasonable desire, and instruction of others meek and zealous per- sons whom the like doubts might hinder. As to the contentious and arrogant reasoners, I leave them to the mercy of the Lord.” The grasp of his mind, the unaffected simplicity of his nature, the extent and variety of his knowledge, are all again manifested in this addition to his theological labours. It is written in the same clear and condensed style as the principal commentary, and in like manner is composed under the form of distinct propositions, each supported by a chapter of proofs and arguments, in which the most familiar examples are mingled with deep research. The enumeration of these propositions will point out the nature of the doubts NAPIER OF MERCHISTON. 325 which, in the course of eighteen years, had suggested themselves to Protestant divines. “1. That the space betwixt one year of jubilee and the next year of jubilee is 49 years precisely, and not 50 years as some do suppose. 2. That the year of God 71, and consequently each 49 years thereafter, are jubilee years, and not the years of Christ’s birth, as some suppose, nor of Christ’s passion, as others. 3. How and for what causes both the last seal, and first vial or trumpet do begin at the destruction of Jerusalem in anno 71, and not the last seal to end before the trumpets and vials do begin. 4. That the fourth kingdom in Daniel is the monarchy of the Romans, and not the small divided kingdoms of the Seleucians and Syrians, as some of late do suppose. 5. That the little horn in Daniel, chap. vii. doth signify the Roman Anti- christ, and not Antiochus properly, as some suppose. 6. That the Pope’s kingdom, both spiritual and temporal, began in the days of Sylvester L.. be- twixt the years of God 300 and 330. 7. That the Pope, during his foresaid reigns, hath possessed and corrupted the outward and visible face of the church, and hath persecuted God his true church, and made the same to lurk and be- come latent and invisible all these days.” At the time when Napier published his larger work, we find him engaged in the contract with Restalrig ; and in 1611, when he again appeared before the public as a theologian, he was a party to another contract, characteristic of his times, and connected with matters very foreign to his natural bent and occupations. It is well known, that, about the year 1603, the Lennox, in which the philosopher held so extensive an interest, was wasted by the memorable conflict betwixt the chief of Macgregor and Colquhoun of Luss, known by the name of the Field of the Lennox, or the Raid of Glenfroon. Macgregor, having been most treacherously entrapped by the Earl of Argyle, was tried for his life with several of his clan, all of whom, found guilty of slaughter, stouthreif, treason and fire-raising, were gibetted together. John Napier was one of the jury, along with Stewart of Garnetullie, Campbell of Glennor- chie, Robertson of Strowane, Crichton of Cluny, Blair of Blair, Graham of Knokdoliane, Robertson of Fastkeilsie, &c. upon whose verdict this unfortu- nate chief was condemned to die. The clan Gregor, driven to desperation by the relentless pursuit of Argyle and the Campbells, became broken and law- less, and infested the Lennox like banditti. Considering the share he had in the condemnation of their chief, the philosopher could not expect forbearance 326 THE LIFE OF at the hands of these broken men, and the following contract indicates that he found the law of the land no sufficient protection from their inroads. “ At Edinburgh, the 24 day of December, the year of God 1611, it is ap- poyntit, aggreit, and finallie contractit, betwixt Johnne Napeir of Merchistoun on the ane pairt, and James Campbell of Laweris, Coline Campbell of Aber- urquhill, and Johnne Campbell thair brother-germane, on the uther pairt, in manner, forme, and effect as eftir followis ; to wit, forsamekill as baith the saids parteis respecting and considdering the mutuall amitie, frendship, and guidwill quhilk hes been thir divers yeiris bygane betwixt the Lairds cf Merchistoun . and Laweris and thair houssis, and willing that the lyk kyndness, amitie, and frendship, sall still continew betwixt thame in tyme coming; thairfoir, the saidis James Campbell of Laweris, Coline and Johnne Campbellis thair breither, faithfullie promittis, that in cais it sall happin the said Johnne Napeir of Mer- chistoun, or his tennentis of the landis within Menteith and Lennox, to be trub- lit or oppressit in the possessioun of thair said landis, or their guidis and geir, violentlie or be stouth of the name of M‘Grigour, or ony utheris heilland broken men; in that cais, the said James, Coline, and Johnne Campbellis to use thair exact dilligence in causing searsch and try the committaris and doars of the said crymes : and, on the uther pairt, the said Johnne Napeir of Merchistoune promittis and oblissis him and his airis to fortifie and assist with the saidis James, Coline, and Johnne Campbellis in all thair leasum and honest effairis, as occasioun sall offer; and herit baith the said parteis faithfullie promittis, binds, and oblissis thame, henc ende, to utheris.

Could he have known the song (for he loved the muses) which that raid was yet to call forth from the genius of the greatest man, next to himself, whom Scotland has produced,—could he have heard the wild names of hes own Levenax so enchantingly mingled,—he would have forgiven the Macgregor.

High as he stood in the estimation of his country for talents of no ordi- nary kind, it was not in his own lifetime that his power could be appreciated. Searcely conscious himself of the magnitude of the achievement, and while he was seeking his immortality in other speculations even more unapproachable, he had broken the spell which through all ages had bound the genius of num- bers in her mysterious labyrinths,—which, invincible to the schools of Greece, and undisturbed by the revival of letters, had baffled Archimedes and tortured Kepler. In the year 1614, when his mind had exhausted the body, and, to use his own expressions to Charles I., “ now almost spent with sicknesse !” Napier published his M1r1F1cI CANONIS DEscRIPTIO LOGARITHMORUM. * See the note to this line in the Lady of the Lake for an account of this raid, and the subse- quent fate of the Macgregor and his clan. 328 THE LIFE OF CHAPTER IX. THAT our own estimate may not seem hyperbolical to those who may ima- gine the Logarithms to be “ but an useful abbreviation of a particular branch of the mathematics,” * we shall commence this chapter with the words of a phi- losopher who knew what he was writing about. “ It will be admitted,” says Sir John Leslie, “ that artificial helps may prove useful in laborious and pro- tracted multiplications by sparing the exercise of memory, and preventing the attention from being overstrained. Of this description are the Rods or Bones, which we owe to the early studies of the great Napier, whose life, devoted to the improvement of the science of calculation, was crowned by the invention of logarithms, the noblest conquest ever achieved by man.” + He who wrote this sentence was no granter of propositions, or one very widely awake to excel- lence in others; nor had he any ties, beyond the sympathies of science, to him he so ardently eulogized. But he was deeply imbued with the powers of num- bers, and knew, if any man did, the relative value of every conquest in the _ mathematics; he pronounced this eulogy in the full freshness and vigour of his own mathematical mind, and while deliberately and profoundly tracing through every age, and in all countries, the triumphs of logistic. It may be said, however, that such praise must be exaggerated, because, assuming that the Scotch philosopher attained what the schools of Greece and the lights of Germany were unable to accomplish, yet England produced Newton! Unquestionably, the author of the modern analysis, the discoverer of the composition of light, the prophet of universal gravitation, is “ immortal * Pinkerton. t Leshe’s Philosophy of Arithmetic. 3 NAPIER OF MERCHISTON. 329 by so many titles,” that no country and no age can point to his equal. But, (without taking into account many peculiar disadvantages under which Napier laboured,) if we consider what really constitutes the magnitude of any conquest which an individual can claim, we will be inclined to admit, that the expressions used by Sir John Leslie are not the loose and exaggerated utterance of admira- tion, but must have been founded upon a deliberate review, and just estimate of such claims; for if it be true that the test of the noblest conquest which huma- nity could achieve is, first, the indication it affords of abstract mental power, and, second, the utility and extent of its practical application to human neces- sities, as well as to physical research, not all the marvellous combinations in Newton’s mind, of mathematical resources with applicate skill, will wrest from Napier the eulogy he has obtained. In respect of its indications of abstract mental power, * his invention or discovery, (for it combines the characteristics of both,) must, it is true, un- dergo a comparison with the fluxionary calculus of Newton ; and by an au- thority, at least as high as what we have quoted, that wonderful analysis was pronounced to be “ the greatest discovery ever made in the mathema- tical sciences.” But the same author, in the same work, had previously declar- ed, after a minute inspection of the intellectual order of the Logarithms, “ Of Napier, therefore, if of any man, it may safely be pronounced, that his name will never be eclipsed by any one more conspicuous, or his invention supersed- ed by any thing more valuable.” + Nor are these eulogies of Napier and Newton inconsistent with each other. The higher calculus was not so much an indivi- dual conquest, as the grand result of a succession of victories under separate leaders, and during distinct campaigns. Euclid, Cavalieri, and Descartes paved the way directly to that calculus. The torch that fired the pile had been passed from hand to hand through a succession of ages; and while a series of the * La PLACE, a name second only to Newton in modern science, was struck with the abstract grandeur of Napier’s invention, which he thus powerfully characterises :—“ I] (Kepler) eut dans ses derniéres années, l’avantage de voir naitre, et de profiter de la découverte des Logarythmes, artifice admirable, di a Neper, Baron Ecossais ; et qui, en reduisant a quelques heures, le travail de plusieurs mois, double, si l’on peut ainsi dire, la vie des astronomes, et leur épargne les erreurs et les dégofits inséparable des longs calculs ; invention d’autant plus satisfaisante pour l’esprit humain, qu’ il l’a tirée en entier de son propre fonds. Dans les arts, l’homme emploie les maté- riaux et les forces de la nature pour accroitre sa puissance ; mas ici, tout est son ouvrage.’—Sys- téme du Monde, Tome ii. p. 266. + Professor Playfair’s Dissertation. het 330 THE LIFE OF most illustrious names in the annals of speculative power mark a constant progress to the point where Newton and Leibnitz simultaneously conquered, that gradual approach was latterly covered and fortified by a cloud of skir- mishers, whose collateral aid, illustrated by such names as Torricelli, Roberval, Fermat, Huygens and Barrow, well deserves to be remembered. ‘The invention of Logarithms presents a different aspect. They were the result of an un- aided, isolated speculation, and unlooked for when they appeared ; a victory, in short, in defiance of all established rules of progressive knowledge and systematic conquest. * The algebraic analysis ought to have preceded the in- vention of logarithms. “ Though logarithms (says Playfair) had not been in- vented by Napier, they would have been discovered in the progress of the alge- braic analysis, when the arithmetic of powers and exponents, both integral and fractional, came to be fully understood. The idea of considering all numbers as powers of one given number would then have readily occurred, and the doctrine of series would have greatly facilitated the calculations which it was necessary to undertake. Napier had none of these advantages, and they were all sup- plied by the resources of his own mind.” What right had a philosopher of the stateenth century, born and bred, too, among the savages of Scotland,— ** Scotus Baro, cujus nomen mihi extitit,’+ as Kepler at first designed him,— to anticipate triumphs which, in the order of things, belonged to the close of the seventeenth ! What had he to do with so powerful a command of the doc- trine of series, and the theory of indices, before that department of mathematical science was evolved,—or with the fruit of a tree before it was planted! He had, it seems, resources within himself, by means of which, outstripping the slow progress of science, he attained a point, the natural intermediate steps to which were yet to compose the conquests of future philosophers. So, when the * Sir David Brewster, speaking of the astronomical discoveries of Newton, says, “ Pre-eminent as his triumphs have been, it would be unjust to affirm that they were achieved by his single arm. The torch of many a preceding age had thrown its light into the strongholds of the material uni- verse, and the grasp of many a powerful hand had pulled down the most impregnable of its defences. An alliance, indeed, of many kindred spirits had been long struggling in this great cause, and Newton was but the leader of their mighty phalanx,—the director of their combined genius,—the general who won the victory, and therefore wears the laurels.”—Life of Newton. This last was for the benefit of military men ; and we may add, that, in the great fight of the se- venteenth century, Bacon was quarter-master-general, and surveyed the country; but Napier, so rapid in his evolution of numbers, commanded the cavalry, was first in action, and the enemy ne- ver recovered his first charge. Thus Britain won the day. + A Scotch Baron whose name has escaped me.—Kepleri Epistole. NAPIER OF MERCHISTON. 331 illustrious adventurers, who long after his time followed the exciting and ever- growing path of analytical discovery, by which the shrine of the higher calcu- lus was at length unveiled, detected in their progress the shrine of the logarithms too, there was nothing to seize, for that spell had been broken already. On the other hand, so far as regards practical utility, what may compete with the invention ? A modern astronomer could better spare his telescope than his tables of calculation ; and almost miraculous as is the power of the infinites- mal analysis, the finest steps in the working of that exhaustless instrument of human investigation are dependent upon the aid of logarithms. When New- ton attained the analysis, he had been already gifted with that engine, which ultimately afforded his calculus “ many of the most refined and most valuable of its resources.”* He had, it is true, only to contemplate the logarithms through the medium of his own analysis in order to obtain a far simpler view and easier command of the former invention than its author could possess ; but it must ever be remembered, that, although Newton had the logarithms when he discovered the calculus, Napier had not the calculus, nor the steps which led to the calculus, when he conceived, discovered, and computed the logarithms. While, even in the comparison of practical utility, Napier’s invention claims a sublime fellowship with Newton’s, the latter does not descend in like man- ner to mere mortal necessities. Logarithms are so useful and prevalent in the ordinary arts of life, that many a practical man is most efficient with those tables, who neither knows nor cares about the mystery of their construc- tion, and would sooner think of mastering the craft of his own spectacles, than the fine theory of that invention. The practical application is familiar to the antiphilosophical midshipman at sea; yet, so uncertain was the art of naviga- tion until this aid raised it to the sciences, that the scriptural prophecy, “ Multi pertransibunt et augebitur scientia,’ + may be said only to have been fulfilled when the logarithms were published. High, then, and in- disputable as is the throne of Newton, Professor Leslie was right, and used no exaggerated expressions, when he called Napier’s invention the noblest conquest ever achieved by man; and, the more closely the mathematical achievements of all ages are examined, the more just will this eulogy appear. Of the two great branches of mathematical science, arithmetic and geome- * Playfair. + « Many shall go to and fro, and knowledge shall be increased.” 332 THE LIFE OF try, the first devoted to the properties of numbers, and the latter to those of extension or space, unquestionably the most recondite, the most fertile, and the most generally useful is the science of numbers. To the highest order of the theory, or purely abstract consideration of numbers, and to the most beneficial results of their practice, the system of logarithms equally belongs. When the restorers of letters gradually recovered the fragments of anti- quity, and gladdened the world with riches redeemed from the lava of bar- barity, there were no mathematical resources disclosed which could equal in power and beauty that which Scotland can claim as her own. The fame of the Grecian schools is chiefly founded upon their combinations of the properties of space, possessing a purity of abstract speculation, and a severity of reasoning, which, if that mystical estimate of mathematical excel- lence could be admitted now, would still place them above all the efforts of mind. Conspicuous among these mathematical attainments is the geome- trical analysis, an invention ascribed to Plato, and which constitutes the power and the glory of the Grecian schools. Synthesis was the original and usual mode of the ancient geometry. It consisted in the art of build- ing one elementary truth upon another, commencing with some acknow- ledged principle, until the problem was solved, or the proposition demon- strated. This method is peculiarly adapted to the communication of ac- quired knowledge. The genius of Plato conceived the bolder instrument of analysis, a method not possessing the severity and caution of synthetical demon- stration, but which at the same time is peculiarly calculated to enlarge the limits of science by the discovery of unknown truths. ‘ The geometrical analysis,” says Playfair, “is one of the most ingenious and beautiful contrivances in the ma- thematics. It is a method of discovering truth by reasoning concerning things unknown, or propositions merely supposed, as if the one were given, or the other were really true. A quantity that is unknown is only to be found from the relations which it bears to quantities that are known. By reasoning on these relations, we come at last to some one so simple that the thing sought is thereby determined. By this analytical process, therefore, the thing re- quired is discovered, and we are at the same time put in possession of an in- strument by which new truths may be found out, and which, when skill in using it has been acquired by practice, may be applied to an unlimited extent. A similar process enables us to discover the demonstrations of propositions, supposed to be true, or, if not true, to discover that they are false. This me- 4 NAPIER OF MERCHISTON. 333 thod (he adds) was perhaps the most valuable part of the ancient mathema- tics, in as much as a method of discovering truth is more valuable than the truths it has already discovered.” * Apollonius, who graced the school of Alexandria about the period when the career of Archimedes was so violently closed at the siege of Syracuse, and who is thought by some to have more than compensated the world for the loss of the Sicilian philosopher, distinguished himself by a profound application of the ancient analysis. He was born at Perga about 150 years before the Christ- ian era; and while, on the one hand, the grasp of his genius unlocked some of the richest stores of modern research, on the other, his restless ingenuity be- stowed upon the ancient system one of the most imposing of its errors. En- dowed, like Archimedes, with a mind capable of extracting the latent powers of numbers, but checked and hampered by the feeble notation of the Greeks, he supplied the defect as he best could, from his geometrical resources, and though he stretched the arithmetic of his times beyond its imagined capabili- ties, it cannot be said that he effected a revolution in that slumbering science. His genius followed a less recondite but more seducing path. The genesis and properties of those curves which are obtained from the cone deeply engaged him whom his countrymen deservedly styled the Geometer par ex- cellence. Though generally referred to the school of Plato, the precise ori- gin of this important branch of geometry is not determined. Conic sections have become of infinite value to physical astronomy, since the curves which the planets and comets describe in space, the law of projectiles, and a mul- titude of physico-mathematical problems have been demonstrated to depend upon their theory. “ What,” says Montucla, “ would have been the ec- stasy of Plato, and the geometers of his school, could they have foreseen the demonstration.” It is to Apollonius, however, that we are chiefly indebt- ed for this profound and beautiful aid. His treatise on the subject, the most distinguished of his many compositious, almost entitle him to be considered the inventor of that branch of geometry; for while the first books have intro- duced us to so much of the theory as, we learn from himself, had been known before his time, the latter are undoubtedly the produce of his own genius, and compose the climax of those speculations. But while Apollonius bestowed this boon upon physical astronomy, and, by his elaborate and profound researches, “ had laid the foundation of * Dissertation. 334. THE LIFE OF discoveries which were to illustrate very distant ages,” he at the same time, by his celebrated hypothesis of epicycles and deferents, greatly prolonged the false, though plausible system of the earth’s repose amid the revoly- ing stars. The method consisted of a geometrical artifice, by means of which certain celestial observations, difficult to reconcile with the establish- ed doctrines of ancient astronomy, were accounted for in a manner which, according to the Greek expression, “ saved the phenomena.”* It had been ob- served from the most remote antiquity, that certain planets traversed the Heavens in distracted or perturbed paths, wholly inconsistent with the simple idea of a circle or perfect revolution, an order the ancients were most unwilling to reject. Cumbrous artifices were readily adopted by way of protecting the original suppo- sition of that simple uniform motion. The system of Aristotle and Eudoxes had inclosed the earth within concentric spheres, to whose revolving surfaces the pla- nets were fancifully attached, and through whose crystalline substances their rays were supposed to be transmitted. In the progress of time, this complicated ma- chinery, though not positively discarded, faded from the imagination, and the planets were permitted to describe their airy circles without the leading-strings of the crystalline spheres. Buttheir unequal movements could not escape the ob- servations of the most defective astronomy. Sometimes they seemed to check their career, to become stationary, and, fmally, to perform a retrograde motion ; and the eternal orbs had thus the appearance of tottering in their gait with the capricious movements of chaos, or the undetermined steps of infant creation. Pythagoras, who long before had caught a glimpse of the truth, failed to es- tablish, though he partly promulgated, the doctrines of the solar system. Apol- lonius bent his mind to reduce the false terrestrial system within the power and the protection of geometry, and he demonstrated a hypothesis the most ingenious and beautiful that ever served to perpetuate error. He imagined the planets to describe a small circle or orbit round a centre, which centre at the same time described a great orbit round the earth. It is obvious, that, upon this supposition, the planet would assume the phases, sometimes of accompany - ing the orbit described by the centre of its smaller orbit, and sometimes of a stationary, or even a retrograde opposition. The smaller circle he named * Milton alludes to this in Paradise Lost. “ To save appearances, how gird the sphere With centric and eccentric scribbled o'er, Cycle and epicycle, orb in orb.” NAPIER OF MERCHISTON. 335 epicycle, and the larger one deferent, or that which carried along with it the smaller. Apollonius was succeeded by Hipparchus, who, notwithstanding the ardour and ingenuity of such researches before his time, deserves to be called the founder of astronomy as a systematic science. No rapid glance can do justice to the value and variety of his speculations. The motions of the most im- portant luminaries, the sun and moon, he detected and demostrated with a per- severance and dexterity worthy of Newton, and thus amended the solar year. He was the first to conceive and execute the stupendous task of forming a ca- talogue of the stars. He founded the science of trigonometry. With him closed the Pagan era, for he is the last philosopher of great account before the rise of Ptolemy, who flourished in the second century. Ptolemy, “ prince of astronomers,” marks a great epoch in the history of science. ‘The Ptolemaic system founded on the labours of Hipparchus, com- bining all the power and weakness of the ancient geometry, was submerged in the dark ages, and, after that dreary hybernation of letters, reappeared to triumph for a time over truth, and to be invested with the terrors of Rome. The schools of Alexandria, towards which we have cast a glance so hurried. and imperfect, were thus illustrated by men whose names are immortal. Phy- sical inquiry, had arrived through a train of brilliant speculations to the basis of Hipparchus, and the system of Ptolemy. The task alone, had he done no more, of enumerating and recording the stars, evinces in the former philoso- pher a mind equal to any intellectual daring ; but the fact, that three centu- ries of apathy intervened before another philosopher like himself arose in Ptolemy, and that Ptolemy did no more with the resources of his predecessors and his own, than erect a dazzling fabric of error, argues some great defect in the machinery of human investigation. This defect may be told ina single sentence. It wasan age of geometrical, rather than of arithmetical science. All its boasted analysis was devoted to diagrams and abstract properties of space. The Grecian philosophers were slaves to the rule and compass, and not aware that the pure reasoning in which they delighted, and the elegant constructions they worshipped, were but vain shadows compared with what the human mind was destined to per- form with numerical aids. It was in that very department of science where the greatest conquests are to be achieved, the science of arithmetic, that Greece 336 THE LIFE OF has least pretensions to rival an era of logarithms. In the weakness of its arithmetic, and the almost vicious refinement of its geometry, lurk the defects which have stampt upon its loftiest monuments the title of splendide mendax. We must not say, however, that the Greeks were destitute of numerical resources. Mathematical investigation is absolutely powerless without some mode of applying the properties of numbers, and such speculations very readily suggest themselves to all stages of civilized humanity. It was im- possible that a nation so refined should exhibit none of its genius and inge- nuity upon a subject so profound and valuable as the philosophy of arithmetic, and, accordingly, though neither justly appreciated, nor systematically culti- vated among them, that science derived illustrious aid from the schools to which belonged Euclid, Archimedes, Apollonius, Ptolemy and Diophantus. The oldest treatise on the theory of arithmetic extant is that comprehended by the seventh, eighth, and ninth books of Euclid’s Elements. But to Ar- chimedes we must chiefly turn in this rapid survey, for of all the sages of anti- quity he is the one with whom a variety of coincidencies entitle us to compare our own philosopher ; and we are the more anxious to do so, because Napier is the solitary being who raises Scotland to that level in the history of science. Thales and Pythagoras had travelled to the east, from whence, as is said, they enriched their own country with some of the mathematical powers, and more of the mystical properties of numbers. Archimedes, who lived some cen- turies afterwards, found the arithmetic of the school of Alexandria sufficiently advanced to attract his mind occasionally from the seductions of geometry, in order to attempt new conquests in numbers. The Greeks, who had adopted the decimal scale, ascended so far in their notation as to include the four terms of the progression, units, tens, hundreds, thousands ; and attained by cumbrous artifices a still further extension, until they could reckon myriads. But all their efforts seemed to be paralyzed by the figurative part of their system, which, instead of being composed of symbols exclusively devoted to that pur- pose, as in the simple but powerful method of Arabic notation, derived its numeral characters from the Greek alphabet, most ingeniously and scientifically combined, but affording very unwieldy and feeble instruments of calculation. For instance, instead of such characters as those now in use, 1, 2,:3,/4,.5, 6, 7, 8,9, the Greeks employed , 8, y, 0, ¢, s, Z, 1, 8, to express the same quan- titative ideas, being the first letters of their alphabet, with one auxiliary sym- NAPIER OF MERCHISTON. 337 bol, episémon intercalated betwixt ¢ and %. This was their series of units ; but instead of the admirable artifice which forms the peculiar merit of the present method, namely, that which expresses the succeeding series in the de- nary scale by repeating the same symbols raised to the requisite value by a change of position, the Greeks continued to exhaust their alphabet. Their defects will be better understood by glancing at the system which now prevails. The Arabic notation is that in which the advance of any of the symbols of unity one step from right to left, has the effect of increas- ing its value ten times, in other words, of multiplying it by ten. But if this were done in empty space, so as to leave no trace of the starting point, the change of position would not be perceptible. To obviate this diff- culty, a circular figure or cypher, expressive of no value in itself, and conse- quently termed nothing, is used for the purpose of indicating that origi- nal position. In this manner, 10 comes to signify ten, because the cypher indicates that the unit has been advanced a step from right to left, and con- sequently has increased tenfold. It is not the addition of the circle which gives the increased value, (a view of this personification of nothing which might vaguely present itself,) for nothing added to one leaves one still, but it is the relative position to which the expressive unit has been shifted. Any of the series of units advanced in like manner obtains its corresponding in- crease. 20 is 2 advanced tenfold; in other words, twenty. But the circle to supply the vacant place becomes unnecessary when any original value of the digits is to be added to the acquired value of the digit advanced ; 11 in- dicates one ten and one unit; 22, two tens and two units; in other words, eleven, and twenty-two. The infinite extension of this system is obvious upon the slightest inspection of its principle. And such is the rapid wing, so ele- gant in its simple construction, so powerful to make its way, which, flitting through the very bosom of the dark ages, came to the aid of regenerated science from some distant and doubtful clime of the east,—some chiarosciro land of science and superstition. How gladly would the genius of Archimedes have hailed this bird of glorious promise! but it came not to the schools of Alexandria. To express the second term in their denary scale, that is, the series of tens, the Greeks continued to draw upon their alphabet, and selected the letters 1, #, A, 4, ¥, & 0, *, and the auxiliary symbol termed koppa, to signify 10, 20, 30, 40, 50, 60, 70, 80, 90. The ascending term of hundreds, 100, uu 338 THE LIFE OF 200, 300, and so on to 900, was expressed by the letters e, o, 7, v, 0, x, J a, and the third auxiliary intercalation termed sanpi.* In this state of their scale, the greatest number that could be noted was only nine hundred ninety-and-nine, being the sum of the highest expressions in each progression. ‘T’o obtain the pro- gression, 1000, 2000, &c. up to 9000, the nine characters of the progression of units were repeated with a mark below each, thus: a, 6, y, 0, é, C, 1, 4 This extended the grasp of their notation to nine thousand, nine hun- dred, ninety-and-nine. ‘The series of myriads, or tens of thousands, was obtained by placing the sare letter M under any number, to He effect of giving it that value. Thus, M signified one myriad or 10,000 ; M, two my- riads, or 20,000, &c- ‘Two dots placed over the symbol or character were sometimes used for the same purpose. The system of Greek notation,—thus limited to the expression of myriads by devices, which, though sufficiently ingenious and effective to be not un- worthy of that enlightened people, were cumbrous and deficient in the hands of philosophers,—betrayed some of them into the crude proposition, that no combination of numbers was sufficient to express the quantity of the grains of sand composing the shores of the ocean. This idea arose directly from that defect in their notation, which limited any distinct numerical expression to the quantity of myriads or ten thousands. The mind of Archimedes, like that of Napier, surrounded with difficulties, and driven upon its own resources, always led him to attempt either what others had never dreamt of, or what they deemed impossible. He immediately set himself to refute this confident assertion, and his somewhat Quixotic deter- mination was crowned by results far beyond the utility of that particular refutation. It gave birth to the ARENARIUS, a beautiful treatise, which ex- tended the feeble notation of the school of Alexandria, or at least demon- strated the power of doing so, approaching, at the same time, the confines * There were only twenty-four letters in the Greek alphabet, and their scale required twenty- seven. The Greeks, therefore, added three intercalations or auxiliary marks. Before the im- provement of dividing their alphabet into three distinct classes, the Greeks had another very feeble method, which I have not thought it necessary to explain. There were also some varieties and mo- difications of their arithmetical language which I have not mentioned. The reader who wishes to be minutely informed on the subject, will find what he wants in the edition of Archimedes’s works, with a learned Latin commentary, printed at Paris, 1615.

NAPIER OF MERCHISTON. 339 of some of the most precious secrets of arithmetical science, and affording an impulse whose career would have left geometry far behind, had barba- rian conquests not checked its progress. ‘This work is addressed to Gelo, the eldest son of the King of Sicily, the philosopher’s relative, and commences with the following address :—‘ There are some, O Prince Gelo, who ima- gine that the sands are innumerable! I speak not of the sands of Syracuse, or of those which are spread upon the shores of Sicily, but of the sands of the whole world. Others, again, believe that the grains are finite, but that num- bers cannot express them! If the earth itself were composed of sand, whose particles rose to the summits of her mountains, and filled the abysses of the deep, such reasoners would find still greater difficulty in persuading themselves that those sands could be numbered. But I will shew, and by geometrical de- monstrations to which you must bow, that in a system of numbers of my own, which I formerly addressed to Zeuxippus, a progression may be found, exceed- ing not merely the grains of a sphere equal in bulk to the earth, but even to that of the whole universe.” It is not, however, the geometrical demonstra- tions of Archimedes, but his knowledge and command of numerical progres- sions, which here call for our attention; and as this knowledge forms one grand coincidence betwixt his mind and Napier’s, it may be proper to afford a popular explanation of the term. “The physical world,” says an elegant and distinguished writer, “is asystem of progressions ; time is composed of moments added to moments ; animal ex- istence is made up of the progressions of nature, advancing by steps more or less perceptible, from the inanimate molecule, to the animated being honoured with the light of immortality. There are degrees in all the properties of nature, passing through fine gradations, from one extreme to the other. It is nature whom we imitate in the arithmetical progression, ceaselessly adding number to number till, like her, we mount the scale by equal steps from zero, and rise from nothing to infinity. When the human mind passes from addition to mul- tiplication, it has attained a new method of progressing towards infinity. In ceaselessly multiplying one number by another, we advance by steps still equal, but more hurried, more rapid. Such is the geometrical progression.”* To afford a more practical illustration than this beautiful passage, sup- pose a series of numbers either to increase or decrease in such relative propor- tions, that the difference betwixt any two of the numbers, which are together, * Histoire de lAstronomie Moderne, par M. Bailly. 340 THE LIFE OF shall be the same throughout; this will be an arithmetical progression. The simplest example is afforded by a progression continually increasing by unity from nothing. Thus, 0, 1, 2, 3, 4, 5, 6, 7, 8, &c. is a progression where the difference betwixt any two consecutive terms throughout is 1. Again, take another increasing series bearing this relative proportion, that every term is the product of the one immediately preceding, by a common mul- tiplier, and you have a geometrical progression. Thus, 1, 2, 4, 8, 16, &c. is an increasing progression, where each term multiplied by 2 gives the succeed- ing one. The examples in both cases might be varied by adopting other se- ries with the same characteristics, such as 1, 5, 9,13, &c. where the diffe- rence is always 4; and 1, 10, 100, 1000, where the multiplication proceeds by 10. In other words, the arithmetical progression advances in this instance by the uniform addition of 4 to the last term, and the geometrical is propagated by the products of the continual multiplication of the last term by 10. Simple, and almost puerile as these explanations may appear, they involve principles which, in the possession of Archimedes, raised the languid arithmetic of the Greeks to a capacity for great adventure, but in that of Napier, created a revolution in science; and even this simple statement of them will soon find an excuse as we proceed in the illustration of our own philosopher’s intellec- tual achievements, where, in the words of Bailly, “ tout est progression.” It is in the properties and relative analogies of these characteristic series of num- bers, that the mighty powers of calculation lurk; and we have now to consi- der how far those powers were developed by Archimedes in the Arenarius. The expedient of the initial letter M having enabled them to note myriads, with this extension of the system, the Greeks could express anything below ten thou- sand times ten thousand ; in other words, the limit of their notation was the my- riad of myriads. | In this state Archimedes found it, and, of course, when he un- dertook to demonstrate the possibility of expressing a number equivalent to the contents of the vast sphere he imagined, he was under the necessity of extend- ing the scale of notation from this limited to an indefinite grasp. The profound views he entertained of progressions and their properties enabled him to effect his purpose, and in doing so he touched more than one principle im arith- metical science, which, had he mastered them, would have completely unfetter- ed that wing of the mathematics.* In the existing state of the notation he proposed to extend, it was not difficult for a mind like his to perceive that the * It was a saying of Plato, that Arithmetic and Geometry are the two wings of the Mathematics. 4 NAPIER OF MERCHISTON. 341 scale ascended in a geometrical progression, of which the ratio or common mul- tiplier was 10. In order to demonstrate the indefinite grasp of these powers, he continued the geometrical progression by taking its limit, a myriad of my- riads or ten thousand times ten thousand, as the unity of a second order of numbers, ascending in the same geometrical progression by ten, from myriads of myriads as the unity, up to myriads of myriads of this extended progres- sion. This he again took as the unity of a third order, and so on through eight periods, until he obtained a power of notation equivalent to 64 places of the Arabic numerals. To form a just notion of Archimedes’s command of the philosophy of numbers, and also of the comparative excellence of Napier as evinced by his theory of Logarithms, we must have a distinct idea of what the former proposed in the Arenarius, and of the extent to which he carried his ob- servation of the properties of progressions. We shall, therefore, assist what has been stated above by an example, taking the aid of the notation now in use. Their alphabet and auxiliarysymbols, with the other devices, gave the Greeks the command of a decuple scale of eight terms, viz. units, tens, hundreds, thou- sands, myriads, tens of myriads, hundreds of myriads, thousands of myriads, which in our notation would be expressed :— Units, - - 1 Tens, - . - 10 Hundreds, - - 100 Thousands, - - 1,000 Tens of thousands, ahee 10,000 Hundreds of thousands, - 100,000 Millions, - - - 1000,000 Tens of millions, - - 10,000,000 Archimedes took this progression as the first order of a period which he supposed to contain eight orders, each composed like the above of eight terms. This first order he named an octade of the first. To form his octade of the second, he took the eighth term of the first octade multiplied by ten, which gave him myriads of myriads, and this was no arbitrary acceleration, because it was the very next term ina decuple geometrical progression. Thus, myriads of myriads became the unity of a second octade; and, therefore, that which Archimedes proposed to name a unity of an octade of the second, would re- present myriads of myriads, #. e. an hundred millions, The highest term of B42 THE LIFE OF this new octade was equivalent in our notation to 16 figures, or 1 and 15 cy- phers annexed ; thus, Octade of the Second. Units, - - 100,000,000 Tens, : : - 1,000,000,000 Hundreds, - - 10,000,000,000 Thousands, - - 100,000,000,000 Myriads, . : 1,000,000,000,000 Tens of myriads, - - 10,000,000,000,000 Hundreds of myriads, - 100,000,000,000,000 Thousands of myriads, - 1,000,000,000,000,000 This last term, thousands of myriads of the octade of the second, (or, as we would name it, one thousand billions,) multiplied by ten, became in like man- ner the unity of an octade of the third. Eight of these octades were to compose a period, and the highest number of the octade of the eighth, which closed the period, would be equivalent to the expression with us of 1 and 63 cyphers an- nexed. Thus, by adding period to period, Archimedes could extend the ex- pression of his scale ad infinitum. But his first period of octades was sufficient for his problem. Taking not merely the sphere of the world for the bulk of sands, but considering the whole universe as such a sphere, he was able, from his geometrical resources and the abstract power of his mind, to bring the con- tents of this imaginary sphere, by approximating steps, within the grasp of measurement and calculation ; and thus he demonstrated, that this inconceiv- able volume of sand did not contain so many grains as would be expressed by the eighth term of the octade of the eighth, or, as we would say, one thousand decillions, a number beyond the grasp of the human mind, but not of nota- tion. * * Our scale of notation, when divided from right to left into periods of six figures each, gives units, millions, billions, trillions, quadrillions, quintillions, sextillions, septillions, octillions, non- illions, decillions, &c. Now Archimedes’s approximate result was one thousand decillions, or 1000000000000000000000000000000800000000000000000000000000000000. This affords a good illustration of the simplicity and power of Arabic numerals. The single unit moved from right to left in a decuple scale by as many proportional steps as the vacancies or cyphers indicate, gives a mathematically accurate notation of a numerical power which cannot be appreciated even by comparison. For instance, it can be demonstrated, that if a thousand persons employed to reckon money, were each to reckon a hundred pieces in a minute, and work at that rate for ten hours a-day, they would take forty-five years to reckon a billion. NAPIER OF MERCHISTON. 343 Archimedes differed from Napier in this, that our philosopher loved calcu- lation as the light of day, whereas the Sicilian, being a philosopher of the geometrical school of Alexandria, only loved it as a cat loves the brook, into which she will dip her paw for the sake of a fish. But we must sympa- thize with the immortal author of the Arenarius, when we call to mind that he had not the Arabic notation, and that all this tremendous gallop of octades was not rendered easy and pleasant to him by the simple, but omnipotent ex- pedient, of the same symbol expressing a decuple progression to any extent merely bya progressive change of place, leaving a mute mark behind it to indicate each step of its advance. The cumbrous and weak combinations of the initial M, or Mv, were little better than the confused repetitions of a child, who might say myriads of myriads of myriads to express what it could not conceive; and the characteristics of the most simple arithmetical operations of that illustrious school were labour and imperfection. ‘“ The procedure of the Greek arithme- ticians,” says Professor Leslie, ‘“ was necessarily slower and more timid than our simple, yet refined mode of calculation. Each step in the multiplication of complex numbers appeared separate and detached, without any concentra- tion, which the moderns obtain by carrying forward the multiples of ten, and blending together the different members of the product. In ancient Greece, the operations of arithmetic, like writing, advanced from left to right; each part of the multiplier was in succession combined with every part of the mul- tiplicand ; and the several products were distinctly noted, or, for the sake of compactness, grouped and conveniently dispersed till afterwards collected into one general amount.” Profound, therefore, as were the conceptions of Archimedes in the philosophy of arithmetic, he looked askance at calculation as a labour which he loved not, and fain would avoid. But it is remarkable, and most interesting to observe, that the very struggles of this great geometrical mind to escape from such opera- tions, brought it to the verge of all that is most valuable in arithmetical science. The object of the Sicilian was to obtain such abstract powers, as would give him the grasp of numbers, by a geometrical consideration of their properties, and, at the same time, save him from the torture of calculation. Nothing was better suited to his purpose than the doctrine of progressions ; and it is obvious that his system of octades was just an indefinitely extended geometri- cal progression, so classed or divided, indeed, as to facilitate notation, but pos- 344 THE LIFE OF sessing, at the same time, those abstract properties of an uninterrupted series of proportionals, which enabled him, as a geometrician, to detect and to point out results, without actually performing any of the calculations. So it hap- pens, that the profound and elegant monument of his genius which we are considering, possesses the anomalous merit of conveying to the mind a mathematical idea of the number of the sands of the ocean, and infinitely be- yond them, without executing any arithmetical operations. In achieving this it was, that Archimedes touched the bases of three great pillars of modern calculation, the system of Arabic notation, the Logarithms, and the language of Algebra ; and thus, unconsciously, he was at the sources of modern science, before which his own beloved geometry has fallen from her throne, and now lies like a broken mirror, unfit to reflect a true image of the Heavens, though still dazzling us with the glories of ancient Greece. In the first place, it is obvious that the classification proposed in the Are- narius is quite analogous to that so universal now, a fact which the follow- ing tree of our notation will at once present to the eye. &c.

The Greek notation, from the very fact of being so imperfect, varied in its charac- ter,* and the more simple the expedients for raising the value of the digit became, the nearer they approached to the invaluable simplicity of the cypher. Thus «was the unity, «, increased by the subscribed mark to the value of a thou- sand ; the next multiplication was expressed by M, or Mv; had they merely ad- ded another mark below the letter, so much would have been gained, and the idea would have more readily suggested itself of throwing aside auxiliary marks entirely, and making a few symbols answer all the purpose, even in an infinite scale, by a change of place. The very philosophy of progressions might have led Archimedes to this beautiful aid of his decuple system,—a _ philo- sophy so simple, yet so powerful; ‘“ mais ces moyens simples sont le fruit des idées profondes et lumineuse ; tout est progression dans le monde phy- sique.” Had he done so, he would have added the Arabic notation to the denary system, and have been the father of arithmetic. The difference be- twixt his mind and Napier’s seems to be this, that the latter would in like manner have denied the proposition that numbers could not grasp the sands of the sea, and have set himself to demonstrate the contrary; he, too, (as he did) would have developed the properties of progressions; but, instead of shunning the numerical operations, or clinging to his geometry, he would have hailed the dawn of the science of calculation, have instantly attacked the tyranny of notation, and most probably reduced it to the present simplicity of its elements, for we shall find, that to semplify notation was a propensity of Napier’s mind, whose characteristic, in prudentia et stmplicitate, is descriptive of the nature of Arabic numerals. In the second place, Archimedes, anxious, not to perfect the science of calcu- lation, but to avoid its difficulties when having to deal with such a scale, observ- ed and demonstrated certain properties inherent in the principles of its construc- * This will be seen by comparing M. Delambre’s “ Arithmétique des Grecs,” as forming the first chapter of his “ Astronomie Ancienne,” 1817, with the same treatise, as given by M. Pey- rard at the conclusion of his @Zuvres d’Archiméde. The Greek notation is different in the cor- responding passages of the separate editions, and there are other discrepancies perplexing to the student.

Here he reached the base of the Logarithms ; but, totally uncon- scious of the superstructure he might have reared, and entirely engrossed with his particular problem and his race of octades, he left that immortal conquest to slumber unachieved through the dark ages. As his statement of the prin- ciple, however, is essential to the history of Logarithms, we shall give it here. “ It is also of some use” (says Archimedes) “ to know this property. Ifa se- ries of numbers be arranged in geometrical progression from unity, and any two of the terms of that progression be multiplied together, the product will also be a term in the same progression ; and its place will be at the same distance from the larger of the two factors that the lesser factor is from unity ; and its distance from unity will be the same, minus one, that the swm of the dis- tances of the two,factors from unity is distant from unity. For, let A, B, C, D, E, F, G, H, I, K, L, represent any geometrical progression from unity, of which A is the unity; let D be multiplied by H, and let X [the unknown quantity, | represent the product. Take L in the given progression, which is at the same distance [or number of places,] from H that D is from unity. It is to be demonstrated that X is equal to L. Because, since in a geometri- cal progression D is at the same distance from A that L is from H, D is in the same ratio to A that Lis to H. But A multiplied by D gives D; and likewise H multiplied by D gives L; therefore X is equal to L. It is demon- strated, therefore, both that the product is a term in the same progression, and that it is at the same distance from the larger, factor that the lesser is from uni- ty. It is also demonstrated, that this product is at the same distance from unity, minus one, as the sum of the distances of the factors from unity ; for A, B, C, D, E, F, G, H, are as many terms as H is distant from unity, and I, K, L, are less by one than the number of D from unity, but with H they are equal to that number.” * * Xojoyuov 02 ess nou r6de yryvwoxiuevor.

Ar- chimedes detected the property simply in its application to his own scale, as indicating the place of any product of its terms ; but it never entered into his imagination that tables of numbers could be demonstrated and construct- ed, so as to render that of universal application which saved him the trouble of calculation in his problem. ‘To demonstrate the property and its value as applied to a particular progression, was the merit of Archimedes. 'To imagine that NUMBERS might be brought into such a state, as to be subservient to that principle, and then to bring them to that state, was the conquest achiev- ed by Napier. In the one case, the discovery was merely a philosophical de- tection of certain analogies, which no philosopher, busy with such progres- sions, could have failed to observe ; a discovery, in short, which can add no- thing to the fame of Archimedes. In the other case, as we shall find when we come to examine more particularly the nature of Logarithms, the disco- very involved an original conception, which, when we say that Archimedes did not form it, we have said enough to prove, that it was such as the detec- ci A, B, T, A, E, Z, H, ©, I, K, A, moves 02 ecw 6 Ar nal rugamorramraciasw 0 A, TG Or 6 2 yev6- wsvog #50 6X.

We are indebted to Professor Peyrard for sending us to the original, though after much puz- zling over his translation, from not being inclined to doubt the accuracy of an “ ouvrage approuvé par l'Institut, et adopté par le gouvernement pour les Bibliothéques des Lycées. Dédié a sa Majesté !Empereur et Roi.

The Sicilian, then, being a geometer par excellence, anxious to shake himself loose from calcu- lation, and not at all to attempt to turn any property of numbers to such ac- count as to create a revolution in arithmetical science, missed the discovery of Logarithms, as he missed the discovery of Arabic notation ; and he did so, without bequeathing to Napier such aid as, for instance, even Newton obtain- ed towards his conquests in the geometry of infinites, from Wallis’s Arithmetic of Infinites. We have now to add, in the third place, that when Archimedes made use of certain arbitrary signs or characters, to represent any given progression of the nature he required, as A, B, T, A, E, &c. for the given quantities, and X for the unknown, he struck a note prophetic of a vast revolution in the lan- guage of science. Geometrical constructions and arithmetical calculations ex- hibit the actual values of the magnitude or quantities upon which they are brought to bear, and these operations are apt to become painfully unwieldy. This gave birth to algebra, which “ was a contrivance merely to save trouble ; and yet to this contrivance we are indebted for the most philosophical and refin- ed art which men have yet employed for the expression of their thoughts. This scientific language, therefore, like those in common use, has grown up slowly from a very weak and imperfect state, till it has reached the condition in which it is now found.”* Its perfection consists not merely in representing quantities by conventional symbols instead of the natural signs, but also ex- pressing, in an abbreviated form, the operations performed, or supposed to be performed, on those quantities. It is obvious, therefore, that Archimedes had made no advance in this refined art; but still he touched the principle, a fact sometimes overlooked. The distinguished author who has just been quoted, in tracing the progress of science after the revival of letters, says, “ Vieta was the first who employed letters to denote the known as well as the un- known quantities, so that it was with him that the language of algebra first became capable of expressing general truths, and attained to that extension which has since rendered it such a powerful instrument of investigation.” But in the Arenarius, the ancient geometer afforded a hint, at least, of that language, by using letters to represent both the known quantities of his pro- * Playfair.

Its inhabitants felt too secure in their wonderful resources, and the philosopher himself returned to his geometry. The city was taken by surprise, and its protector only became aware of the fact when the rude voices of the Roman soldiers interrupted his studies with an order to appear before Marcellus. The Sicilian is said to have been lying on the ground at the time, intent upon a diagram : “ I will come,” said he, “ when I have finished my problem,”—and the soldier plunged his sword into the philosopher’s bosom. So perished Ar- chimedes, two centuries before the Christian era. A sphere within a cylinder was engraved upon his tomb, in conformity to a desire he had once expressed when exulting in a geometrical conquest. Apollonius succeeded him, and the arithmetic of the Greeks was improved by that philosopher in the proportion that he simplified the notation. But all his improvements were modifications of the system of his predecessor, and his rules for ameliorating calculation arose from the properties pointed out by Ar- chimedes. Apollonius approximated, however, still nearer to the present sys- tem of notation; but the simple expedient of the cypher still eluded the grasp of his mind, and the Logarithms were left undisturbed. The recovered remnants of ancient science are so scattered and imperfect, that no accurate estimate can be formed of the extent to which the impulse prevailed which Archimedes, Apollonius, and Ptolemy bestowed upon the science of calculation. ‘There are some indications that both arithmetic and algebra attained to greater perfection before the barbarian conquests than is generally supposed; and although nature for a time seemed as if exhausted by the production of such philosophers, yet, in the progress of those centuries * Wallis (“ bon juge en ces matiérs,” says Montucla) notices the fact particularly, as one of interest and historical value: “ Quanquam enim Nuwmerorum Cossicorum (quod jam dici solet) seu Denominatorum, aut Algebricorum Nomina, jam recens introducta censeantur, vel ab Ara- bibus, vel a recentioribus Grecis, (inter quos eminet Diophantus) post Huclidis, et Archimedis tempora: res tamen ipsa jam olim obtinuit, estque in his Archimedies numeris, A, B, I, A, &c. conspicua,” &c.—Note in Arenarium. 350 THE LIFE -OF which were still to see the uninterrupted light, men arose whom science might well be proud to call her sons. With Hipparchus, whom we have already noticed, closed the jirst school of Alexandria; Ptolemy and his system mark the rise of the second. This great astronomer was thrown too frequently upon difficult calculations not to benefit by the system of Archimedes, and in his hands it was considerably enriched. He applied with great effect to his as- tronomical researches, the sexagesimal arithmetic, arising out of the division of the circle, (following the ancient year,) into three hundred and sixty degrees, the radius being held equivalent to sixty of those degrees. The sexagesimal scale proceeded upon the same principles as the scale of Archimedes, but fol- lowed.a descending instead of ascending ratio. Ptolemy was even led to the occa- sional use of the Jetter o to indicate a blank in the scale, and we thus see the tendency of the Archimedean system of notation to that now in use, and the gradual and near approach to a treasure which those ill-fated schools were des- tined never to attain. About the middle of the sixteenth. century, however, a Greek fragment was discovered in the Vatican, which proves, that, before the fall of letters, the science of calculation had reared its head so high as to threaten the throne of geometry. Diophantus, among the last who may be named with the most il- lustrious of his country, seems to have escaped that inordinate love of diagrams, which constituted the effeminacy of Grecian science, and composed a work of thirteen books upon arithmetic, whose fragments have occupied the closest attention, and demanded all the illustrative power of such profound modern algebraists as Bachet and Hermat. We thus see the mathematics of that age struggling painfully, but not in vain, to unfold their most powerful wing. A proportional advance in logistic from the system of Ptolemy would have developed the Arabic notation ; a successor to Diophantus, in decuple ascending progression, might have achieved the Logarithms. But other con- quests were now to prevail, and the star of science waned. As if the coming night had cast its shadow before, the successors of Diophantus seem to have anticipated the approach of the dark ages, and, instead of pressing onwards in the vast field of discovery, devoted themselves to the task of collecting and eluci- dating the works of others. To the mathematical collections of Pappus of Alex- andria our own age is indebted for the knowledge of such sublime resources as the geometrical analysis, and the conics of Apollonius. His friend and colleague, NAPIER OF MERCHISTON. 351 Theon, left a Commentary on the Almagest of Ptolemy, and was other- wise distinguished ; but, strange to say, his fame is almost eclipsed by that of his daughter. Hypathia is a rare instance of her sex not only devoted to the silent abstraction of mathematics, but so successful in her studies, as to rank with the immortal philosophers of Greece. She, too, watched with star-like fidelity the closing gates of light, and gemmed like a planet the departing day of Grecian philosophy. Apollonius, Ptolemy, and Diophantus, received the homage of her commentaries. How lived—how loved—how died she ? The fate of Hypathia is not left to conjecture. Cyril, a Christian bi- shop, and his fanatical monks, are accountable for her barbarous murder, which inflicted the last mortal stab upon the expiring school of Alexandria. ** He (Cyril) prompted or accepted the sacrifice of a virgin who professed the religion of the Greeks, and cultivated the friendship of Orestes. Hypathia, the daughter of Theon the mathematician, was initiated in her father’s studies. Her learned comments have elucidated the geometry of Apollonius and Dio- phantus ; and she publicly taught, both at Athens and Alexandria, the philo- sophy of Plato and Aristotle. In the bloom of beauty, and in the maturity of wisdom, the modest maid refused her lovers, and instructed her disciples. The persons most illustrious for their rank or merit were impatient to visit the female philosopher, and Cyril beheld with jealous eye the gorgeous train of horses and slaves who crowded the door of her academy. A rumour was spread among the Christians, that the daughter of Theon was the only obstacle to the reconciliation of the prefect and the archbishop, and that obstacle was speedily removed... On a fatal day, in the holy season of Lent, Hypathia was _ torn from her chariot, stripped naked, dragged to the church, and inhumanly butchered by the hands of Peter the reader, and a troop of savage and merci- less fanatics. Her flesh was scraped from her bones with sharp oyster shells, and her quivering limbs were delivered to the flames. The just progress of inquiry and punishment was stopped by seasonable gifts ; but the murder of Hypathia has imprinted an indelible stain on the character and religion of Cyril of Alexandria.” * The connection of Logarithms with the first of the regenerated sciences, is, * Gibbon’s Decline and Fall of the Roman Empire. 352 THE LIFE OF perhaps, the proudest view that can be taken of them ; and certainly the least fallacious test of the author’s claims, is the instant and ardent homage paid to his genius by philosophers greatly distinguished in rearing the pillars of that most sublime of human monuments, physical astronomy. That Napier was the one destined to create the first important revolution in the means of inquiry which after the dawn of letters enabled the new world of science to surpass the old, was to a certain extent perceived the moment his work became known, though it was impossible to foresee the refined resources of the Newtonian era, to which loga- rithms are so admirably subservient. To the English translation of the Canon Mirificus, which passed through the author’s own hands in manuscript, and received his most cordial imprimatur, many commendatory poems are attached, after the fashion of his times, evincing a more than usual excitement and en- thusiasm. One of them has the following quaint verses, in which some of the lines would not discredit Spencer. Pull off your laurel rayes, you learned Greekes, Let ARCHIMED and Evc ip both give way, For though your pithie sawes have past the pikes Of all opponents, what they e’er could say, And put all moderne writers to a stay, Yet were they intricate, and of small use Till others their ambiguous knots did loose.

Their labours we must first shortly notice, and then turn to those Di majorum gentium who were toiling to rear the superstructure, when Napier appeared to claim for Britain an equal place in that bright page of history to which their names belong. Let us not, however, as we pass, forget Gerbert the monk, more honoured in that simple appellation than even in the title he afterwards attained of Pope Silvester the second. While the science of Greece lay quenched in the dissolution of the Roman Empire, and her very language was forgotten, the Arabs in the East, and the Moors in Spain reaped the honour of preserving both from utter extinction. Gerbert, a Bene- dictine, disgusted with the ignorance of the monkish schools of Europe, sought science in the Moorish Institutions, rich in Arabic versions of the old philoso- phers. He returned like a laden bee, and among his stores appeared the Ara- bic notation, which was more than the Greeks themselves had possessed. Whether India or Arabia gave birth to the system has baffled all inquiry, and the human being who conceived it was destined never to obtain the honour his name deserves. It is the first great revolution in the arithmetic, and consequently in the science of Hurope, and was introduced so early as the tenth century, long before the boon could be well appreciated. Centuries elapsed, however, before Arabic numerals came into active operation, and the claims of their alleged importer are not very distinctly established. He acquired the character of a magician, but escaped the faggot, to reach the loftiest throne in Christendom, that of Antichrist, which the next great benefactor of calculation held in such abhorrence. While darkness still prevailed, another treasure was brought to Europe from the east, os- tensibly of Arabian birth, but now, like the last, generally referred to India. Leonardo of Pisa brought home, with his merchandise, the science of algebra about the commencement of the thirteenth century; but “ the language was very imperfect, corresponding to the infancy of the science, the quantities and the operations being expressed in words with the help only of a few abbrevia- tions.” * These were the resources awaiting philosophers whose high destiny was to restore science to a mightier throne than the one she had lost. But, not- withstanding such valuable acquisitions, the great work of restoration can only be said to have commenced in the fifteenth century, nor was it until the following (in which Napier was born) that the invention of printing began to * Playfair. Y¥y 354 THE LIFE OF have a decided influence on the progress of letters. These historical facts must be kept in view in order fully to appreciate the merit of our own philosopher, or the rank he holds in the history of science. We must also remember how long it was ere the light so slowly expanding over the continent could reach our less favoured island, and that, while its genial warmth was still almost exclusively confined to the cradle of modern astronomy, an independent ray burst from the least propitious quarter of Britain, whose effect was to consum- mate what had been achieved elsewhere. We have hastily reviewed, in refer- ence to mathematical conquests, that first great period, in the history of science, whose characteristic is the exclusive prevalence of geometrical methods ; a period when the absence of those connecting links which now unite mathema- tics and physics was like the separation of soul and body. Unquestionably the greatest men, in an intellectual point of view, whom the world has ever produced, are those who contributed most largely, not merely to the restora- tion of letters, but to the memorable revolution which has reared physical sci- ence upon the basis of calculation. Considering that Euclid wrote on arith- metic, and how nearly Archimedes had unlocked the treasures of logistic, it is no slight commendation of Napier to exclaim “ Let Archimed and Euclid both “* give way ;” but the praise is still higher, “ and bonnets vail you Germans "” for it was in Germany that science first reared her drooping head, and as we watch her restoration under the new influences of arithmetic and algebra, we hail the second period of her history, and cease to regret the first. In the progress of astronomy a branch of science became developed, the im- portant effect of which was to bring the speculative pride of mathematics to minister greatly to physical research. To measure the times and spaces. which fall under the investigation of rational astronomy, was an attempt which could only succeed in the schools of Greece, so far as her philosophers had escaped beyond the enchantments of geometry. Thus it is that Hippar- chus ranks so high in her annals; for in the course of the daring career that led him to catalogue the stars, he applied to a certain extent the science of TR1Go- NOMETRY. Adefinition of this science, derived from the etymology of the word, affords but a feeble sense of its value. Literally, it means the science of the measurement of triangles; but in an extended view, we must call it that which treats of the union betwixt arithmetical and geometrical properties and powers, in the application of mathematics to physics. It is in fact the basis of physi- NAPIER OF MERCHISTON. 355 cal astronomy, which is the temple of modern science. The era of trigonome- trical computation is, in the history of human knowledge, the great period of transition from the exquisite effeminacy of geometrical constructions, to the omnipotent independence of algebra; and without which period of transition, the higher geometry could not have been attained. To this era Napier stands in the same relation that Newton does to the last and greatest period of ma- thematical history. It is not to Hipparchus that Europe owes the introduction of trigonometry. It came, like other strange gifts, from “ Araby the blest,” before a knowledge of the Greek language had revealed the stores of the schools of Alexandria. “The two men,” says Montucla, “to whom the mathematics are most indebt- ed during the fifteenth century are Purbach and Regiomontanus ;” and it was in their hands that trigonometry received its first essential improvements be- yond both the Grecian and Arabian methods. Purbach, so named from his birth-place in Germany, was born in the year 1423, and, while yet a young man, became professor of astronomy at Vienna, where his fame attracted, as a scholar, the famous John Muller, or Regiomontanus, his junior only by a few years. These two are considered as the first who mark the decided dawn of science. Purbach laboured to relieve, as well as to insure accuracy to, the cal- culations of astronomers, by framing numerical tables of various kinds, and he introduced a most important change in trigonometrical arithmetic, by modify- ing the sexagenary system of Ptolemy in the division of the radius of the circle. In Ptolemy’s table the radius was computed at 60 degrees, by which the chords and sines were expressed. Purbach supposed the radius to be di- vided into 600,000 equal parts, and computed the sines of the arcs, for every ten minutes, in such equal parts of the radius by the decimal notation. His death, at the early age of 38, left the rich field of conquest he had opened, to his pupil Regiomontanus.. This philosopher was even more highly dis- tinguished in every branch of science than his master. That of trigonometry, especially, advanced in his hands to a point which only some extraordinary effort could greatly exceed. He carried the system of Purbach, exclusive of the sexa- genary, so far as to have the merit of introducing the first idea of the ordinary practice of decimal fractions, the most valuable addition to arithmetical science since the introduction of Arabic numerals. Thus numbers obtained as it were both their ¢elescope and microscope, though the instruments were rude, and. comparatively feeble until Napier arose. High as Regiomontanus ranks, he 356 THE LIFE OF must indeed “ vail his bonnet” to the Scotchman ; for, in all the proudest eulo- gies of him of Konigsberg, our philosopher’s superiority is expressly admitted. Montucla declares, that Regiomontanus’s system of trigonometry is equal in every respect to that of modern times, if (he adds, however,) we throw out of the comparison the Logarithms, and the trigonometrical theorems of Napier ; and Professor Leslie, in recording the great advance made by the German to- wards decimal fractions, has these observations :—“‘ To count downwards might seem as easy as to reckon upwards. But the mode of denoting the ranks of decimals was then most cumbrous, the successive numerals, like the indices in algebra, being inclosed in small circles. Bayer, in 1619, proposed to substitute for these complex marks an accent repeated. It was our illus- trious countryman Napier, however, that brought the notation of decimals to its ultimate simplicity, having proposed in his Rhabdologia, printed two years earlier, to reject entirely the marks placed over the fractions, and merely to set a point at the end of the units. But his sublime invention of Logarithms about this epoch eclipsed every minor improvement, and as far transcended thedenary notation, as this had surpassed the numeral system of the Greeks.” * Regiomontanus died in 14'75, suddenly cut off, like his master, in the flower of his age, having lived to revolutionize the trigonometrical system of Ptolemy. But a child was already born, from whom the Ptolemaic system of the universe was to receive a signal overthrow. NIcHOLAS COPERNICUS, the author of the True System of the World, was born in Prussia about the year 1473. Regiomontanus, says M. Bailly, “ from his deathbed transmitted to the infant Copernicus that torch of astronomy which he had received from Purbach.” Certainly no one could have been worthier to receive it. His genius escaping the enchantments that beset its path, and which dazzled and seduced even his successors, penetrated, through the labyrinths of epicycles and crystalline spheres, back to the throne of Pythagoras where it read the truth. This in itself was no trifling intellectual exertion, for the power of an established system, though it present the most clumsy combinations of ig- norance or accident, may be fortified and even hallowed by time; and the incongruities of this ancient system of the world, being entirely concealed from vulgar sense by optical illusion, were also shrouded or softened to the philoso- phic view by geometrical demonstrations. But the unfettered mind of Coper- * Leslie’s continuation of Playfair’s Dissertation. See also Delambre, Histoire de L’ Astrono- mie Moderne, 'T. 1. p. 494. NAPIER OF MERCHISTON. 357 nicus brooded over the doctrine of Pythagoras, that the sun alone was worthy to occupy the centre of the system,—from the stores of Cicero he seized the fact, more precious than his eloquence, that Nicetas of Syracuse had accounted for the rising and setting of the stars, by the supposition of the earth’s mo- tion round its own axis ; and from the union of these long-rejected specula- tions, he conceived and formed a planetary system destructive of the Ptole- maic. This invaluable work he reserved for his friends and disciples, and only gave it to the world about the close of his life. In the year 1507, the thirty-fourth of his age, he had already rejected the idols of antiquity, and founded the pillars of physical astronomy; but it was not until the year 1543 that his disciple, Rheticus, undertook to superintend the publica- tion of the new doctrines at Nuremberg. In his preface to the Pope, Coper- nicus deprecates theological calumnies, and claims the powerful protection of Paul III. But he neither lived to endure or to defeat persecution ; stricken in years, he was just able to touch the volume, which his friends had hurried from the press to his deathbed, when he expired in peace, a few years before the birth of Napier. Copernicus produced a treatise on trigonometry about the commencement of the sixteenth century ; and his favourite pupil, George Joachim Rheticus, who became professor of mathematics in the University of Wurtemberg, dis- tinguished himself greatly by his trigonometrical canon, published in 1596, which still further advanced the science. About the same time appeared the Geometria Triangulorum of Philip Lansbergius, in four books, enriched with all the increased store of sines, tangents, and secants. Dr Hutton calls this “a brief but very elegant work, the whole being clearly explained, and is per- haps the first set of tables titled with those words.” The same author also mentions the trigonometry of Bartholomew Pitiscus, first published at Franc- fort in the year 1599; and commends it as “ a very compleat work, contain- ing, besides the triangular canon, with its construction and use in resolving triangles, the application of trigonometry to problems of Surveying, Altimetry, Architecture, Geography, Dialling, and Astronomy.”* This is no doubt, “ that clearer font of Hellespont,” to which our philosopher’s quaint eulogist refers. Through such hands the science of trigonometry had arrived at great per- fection, and the magic circle, clothed with its full complement of lines and angles, seemed now to menace the heavens. But numerical powers had not * History of Trigonometry attached to Hutton’s Tables of Logarithms. 358 THE LIFE OF kept pace; so there was an inevitable tendency to shrink from the Herculean task of co-extensive computation, and to relapse into the illusions of sense. It is the remark of Herschel, that, “ in all cases which admit of numeration or measurement, it is of the utmost consequence to obtain precise numerical state- ments, whether in the measure of time, space, or quantity of any kind. Nu- merical precision is the very soul of science, and its attainment affords the only criterion, or at least the best, of the truth of theories, and the correctness of experiments. Thus, it was entirely to the omission of exact numerical de- terminations of quantity that the mistakes and confusion of the Stahlian che- mistry were attributable,—a confusion which dissipated like a morning mist as soon as precision in this respect came to be regarded as essential.”* But while the quantities of chemistry, and the laws of other mundane sciences, or the ordinary estimates of time, space, or velocity, could be readily subjected to the rigor of numbers, the eternal systems to whose vastness trigonometry aspired, presented at each new inspection some Archimedean labour, and it was in vain to attempt precision where there was not the power. TycHo BRrAHE, born four years sooner than Napier, was the last philosopher destined to attempt such achievements without the aid of logarithms; yet he was the first of great renown to whom the coming boon was announced, though he lived not to witness their promulgation, or to comprehend the reality of that announcement. He was born in the year 1546, of a noble family in Denmark, still holding its rank there, and became one of the most distinguished astrono- mers of any age or country. He is generally named after Copernicus in the history of all that is illustrious in science; and stands unrivalled for ardour in astronomical pursuits, as well as for the magnificent scale upon which he conducted his observations. He appeared at a critical time for the advance- ment of physical research. The great union betwixt speculative and practical science had been partially effected ; but the applicate means were still in the infant state, to which the talents, zeal, and good fortune of Tycho were emi- nently capable of bringing the necessary impulse. From the rise of this phi- losopher may be dated the era of astronomical instruments, and the establish- ment of a complete practical system. Even his besetting sin had a whole- some effect, being precisely the reverse of what had retarded the Grecian schools. He was fonder of observing than of abstract reflection ; and so greedy * Discourse on the Study of Natural Philosophy. This beautiful treatise is not indebted, like Powell’s, to the Scotch Dissertations. NAPIER OF MERCHISTON. 359 of practical excitement, that he occupied his whole genius with the means of gra- tifying that taste. In the early part of his career he is said to have applied himself diligently to discover the philosopher’s stone, and for the most part of his life was as much devoted to chemistry as his loftier pursuits would allow. Two events of his youth seemed to augur a less favourable career in life than what afterwards befel him. Having engaged in a dispute with a friend on the subject of mathematics, the young philosophers brought the question to the arbitrement of their swords, and Tycho lost his nose. This combat took place at seven o’clock of a dark evening in December, the very stars hiding themselves for shame. But the future King of Uranibourg was no ways daunted by his loss, and the manner in which he supplied it is characteristic of the magnificence of all his ideas and habits. He would have disdained that savage borrowing from the forehead, of which modern surgery is so vain; and he rather gloried in an opportunity of obtaining a finer nose than any other man. Accordingly, he framed one of gold, silver, and ivory, exquisitely mingled, and with this he feared not to look Heaven in the face.* Shortly afterwards, he fell in love with a beautiful peasant girl, and married her, to the great displeasure of his noble family, who treated him so rigorously in consequence, that the King of Denmark thought it necessary to interpose his good offices. This gave rise to the illustrious patronage which was fortunate for science. Frederick II. proved himself to be worthier of Tycho for a subject, than James VI. was of Napier. The King of Scotland aspired to be a patron of pedagogues, while his greatest philosopher, the most unobtrusive of human beings, was constrained to remind him, “ that here are within your realm (as well as in other countries) godly and good ingynes, versed and exercised in all manner of honest science and godly discipline, who, by your Majesties instigation, might yield forth works and fruits worthy of memory, which otherwise (lacking some mighty Mecenas to incourage them) may perhaps be buried with eternal silence.” At the date of this letter, King James had just returned from visiting Tycho at Uranibourg. There, on the island of Huen, situated at the mouth of the Baltic, Frederick had placed his philosopher on a prouder throne than his own, adding honours and revenues, and every aid * Histoire des Philosophes Modernes par M. Sayerien. Tome V. p. 40. The author adds, «“ qu’il étoit si bien fait et si bien ajusté, que tout le monde le croyoit naturel. Cela peut étre, mais on ne congoit pas comment J’or et l’argent pouvoient imiter la chair, ces deux métaux étoient apparement caches.” 360 THE LIFE OF and encouragement that an astronomer could desite. Arabia had been lavish of her stores to renovated science, and now her most romantic tales of magic splendour seemed realized in the north. Upon the 8th of August 1576, the first stone of the far-famed castle of Uranibourg was laid in Tycho’s principality. The island, about eight miles in circumference, rises by a gentle elevation so as to command the sea and the horizon on all sides, and the edifice with which it was honoured was as royal as the gift. It was of a quadrangular form, the dimensions being sixty feet every way, and flanked with lofty towers thirty-two feet in diameter, the observatories of this palace of science. Ty- cho’s whole establishment was in keeping with the magnificence of his dwel- ling, where his gold and ivory nose seemed no longer out of place. Like other potentates, he kept an idiot, but gifted with second sight, who, as we have elsewhere noted, sat at his feet at meals. Tycho is also said to have fitted up his palace with certain mysterious tubes, and other telegraphic con- trivances, which enabled him to communicate with his domestics as if by magic, and to obtain secret knowledge of his many visitors long before their arrival. But could the King of Denmark have given his philosopher the Loga- rithms, he would have done more for his fame. If, to Arabic splendour, he could have added the power that still lay hid in Arabic numbers, a false sys- tem of the world might not have been re-established at Huen. With such numerical aid, Tycho’s observations, escaping the illusions of sense, would have become imbued with what Herschel so justly calls, “ the very soul of science ;” and thus, gifted with powers of calculation beyond even his pupil Kepler, it might not have been left for the latter to become “ the legislator of the heavens.” Tycho catalogued the stars with an accuracy, and to an extent which threw the labours of Hipparchus and Ptolemy for ever into shade. His instruments, “ were of far greater size, more skilfully contrived, and more nicely divided, than any that had yet been directed to the heavens. By means of them he could measure angles to ten seconds, which may be accounted sixty times the accuracy of the instrument of Ptolemy, or of any that had belong- ed to the school of Alexandria.” But he was, comparatively speaking, feeble in calculation, so he wasted his genius in framing systems out of his own imagination, and fortifying them with his ingenuity. Rejecting that of Copernicus, he took vast credit to himself for superseding the Ptolemaic Sys- tem with his own, which was, pat the sun, attended with the whole cortege: NAPIER OF MERCHISTON. 361 of revolving stars, performed the grand revolution round the central and sta- tionary earth. “ If Tycho had lived before Copernicus, his system would have been a step in the advancement of science; coming after him it was a step backward.” His illustrious pupil Kepler, however, has left a record of what calculation could do to redeem the mind from such erratic flights. He under- took the Herculean task of unravelling the irregular orbit of the planet Mars, and succeeded in determining the relative position of the sun, both in respect of Mars and of the earth, and thus laid the foundation for the true solar system. But in doing so he had to grapple with calculations to which few men in Eu- rope but himself and Napier were equal. “ The industry and~patience of Kepler in this investigation were not less remarkable than his ingenuity and invention. Logarithms were not yet known, so that arithmetical computation, when pushed to great accuracy, was carried on at a vast expense of time and labour. In the calculation of every opposition of Mars, the work filled ten folio pages, and Kepler repeated each calculation ten times, so that the whole work for each opposition extended to one hundred such pages; seven opposi- tions thus calculated produced a large folio volume.” * It is a remarkable fact, and not generally known, that Tycho Brahe was informed of the boon to be conferred upon science, in a very direct communi- cation from Napier himself, twenty years before our philosopher’s other avo- cations, added to the labour of the computations, and his own diffidence, suffer- ed him to give the logarithms to the world. We have already noticed that Sir Archibald Napier’s colleague in the office of justice-depute was Sir Tho- mas Craig of Riccarton. Betwixt the Feudist’s third son, John Craig, and John Napier, a friendship grew up, of which the source is not to be doubted. Young Craig was devoted to mathematical studies, and, although not gifted with those lofty capacities which have placed his friend among the lights of the world, he was an excellent mathematician. There is, indeed, one record which of itself is sufficient to hallow the memory of Dr Craig, though it is rarely met with in his own country, and still seldomer perused. I allude to a small volume of Latin epistles printed at Brunswick in the year 1737, and dedicated by their collector, Rud, Aug. Noltenius, to the Duke of Bruns- wick. The three first letters in the collection are from Craig to Tycho Brahe, and prove that he was upon the most friendly and confidential footing with the Danish astronomer. He addresses Tycho as his “ honored friend,” and signs * Playfair’s Dissertation. ZZ 362 THE LIFE OF himself “your most affectionate John Craig, doctor of philosophy and medicine.” The first letter thus commences: “ About the beginning of last winter that magnificent man Sir William Stuart delivered to me your letter and the book you sent.” The date is not given, but I have seen a mathematical work of Tycho’s in the library of the Edinburgh University, which bears upon the first blank leaf a manuscript sentence in Latin to the following effect: “ To Doctor John Craig of Edinburgh in Scotland, a most illustrious man, and highly gifted with varied and excellent learning, Professor of Medicine, and exceedingly skilled in the mathematics, Tycho Brahe hath sent this gift, and with his own hand hath written this at Uraniburg, 2 November 1588.” It appears from contemporary chronicles, that, in the month of August 1588, Sir William Stuart, commanding the King’s guard, the same who may have been the bearer of Napier’s catoptric proposals to the secretary of Essex, was sent to Denmark to arrange the preliminaries of the King’s marriage, and that he returned to Edinburgh upon the 15th of November 1588. There can be no doubt that the book in the College Library is that referred to in Craig’s epistle to Tycho, which must have been written, therefore, in the begin- ning of the year 1589. Neither can it be doubted that this was Sir Thomas Craig’s third son, Dr John Craig, physician to King James. Napier men- tions him in a letter to his own son, quoted in a previous chapter, where he says, “ Ye sal mind me to Doctor Craig ;” which letter is dated 1608, when Napier’s son and the King’s physician were both with his Majesty in England. That fine old gossip, Anthony a Wood, picked up a story of Napier, Dr Craig, and the Logarithms, which he thus recorded in the Athene Oxonienses. “It must be now known, that one Dr Craig, a Scotchman, perhaps the same mentioned in the Fasti, under the year 1605, among the incorporation, coming out of Denmark into his own country, called upon Joh. Neper, Baron of Mercheston, near Edinburgh, and told him, among other discourses, of a new invention in Denmark (by Longomontanus, as ’tis said,) to save the tedious multiplication and division in astronomical calculations. Neper being solici- tous to know farther of him concerning this matter, he could give no other account of it than that it was by proportional numbers. Which hint Neper taking, he desired him at his return to call upon him again. Craig, after some weeks had passed, did so, and Neper then showed him a rude draught of what he called Canon mirabilis Logarithmorum. Which draught, with some alte- rations, he printing in 1614, it came forthwith into the hands of our author NAPIER OF MERCHISTON. 363 Briggs, and into those of Will. Oughtred, from whom the relation of this matter came.” * It is singular that authors who ought toknowsomething of the theory of loga- rithms have been led by this anecdote to refer their conception in Napier’s mind to such a casual accident, and the production of the canon mirificus to the cogi- tation of afew weeks. Even Dr Charles Hutton, whose mathematical works are so valuable, adopts the opinion, that our philosopher was thus “ urged into action,” and quotes the anecdote as if he believed it literally. Another philosophical writer alludes to the same story in support of his proposition, that Napier’s mind was very ready to take a hint in such matters.+ A hint! why the whole world had been in possession of one since the days of Archimedes. If a hint could have urged any human mind thus rapidly upon the theory of the Lo- garithms, there was a hint which arose in the school of Alexandria, which was submerged in the middle ages, and rose again with the letters of Greece ; which Tycho had—which Stifellius, Byrgius, Longomontanus, and above all Craig, a Scot, doct. of phys. of the * The passage referred to in the Fasti is as follows: “ university of Basil.

There was no other Craig in that capacity, that I am aware of; but there was the well-known Dr John Craig, “ Minister of God’s word to the King’s Majesty,” who was the relative and preceptor of Sir Thomas Craig, and died at the age of 88, in the year 1600. James Baillie, in his Life of Sir Thomas Craig, prefixed to his works, says that the Feudist’s second son was Sir James Craig of Castle Craig and Craigston in Ire- land, and that he left his fortune to his immediate younger brother, “ Joanni Cragio, qui Jacobo VI. medicus ordinarius, Carolo I. archiater fuit.”. Mr Tytler, inhis Life of Craig, p. 246, also says that John Craig, “ became successively physician to James VI. and Charles I.” But Dr Craig died before the reign of Charles I.; for in the Feedera, I find the royal gift of James VI. “dilec- to nobis Johanni Craigio in medicinis doctori officium et locum ordinarii et: primarii medici nostri,” with a hundred pounds of English money per annum, and various perquisites, dated at Westmin- ster, 20th June 1603; and in the same record appears the like gift, dated 9th July 1620, “ Jacobo Chambers in medicinis doctori officium et locum ordinarii medici nostri quod Johannes Craige defunctus nuper tenuit.” The evidence seems complete, that the third son of Sir Thomas Craig,— Napier’s friend,—Tycho’s correspondent,—and King James’ Physician were all one and the same John Craig, who died in 1620. + Tilloch’s Philosophical Magazine, Vol. xviii. p. 53.

If our philosopher really broke the spell in an afternoon’s reflection upon a forenoon’s conversation with Dr Craig, he is a greater man than we took him for; but we shall find that Napier kept beside him, unknown to the world, the construction of his canon, under the name of “ Tabula Artificialis,’ for years before he envented the word Logarithms ; therefore Wood is clearly wrong when he says that Napier called the rude draught (assumed to have been constructed for the occasion) “ Canon Mirabilis Logarithmorum.” The story, however, is not without foundation. Kepler, in a letter to his friend Cugerus, chiefly regarding the economy of the heavenly bodies, after revelling in all the unapproachable sublimities of his calculations, and naming and com- menting upon the most illustrious benefactors of trigonometry, exclaims, “ But nothing, in my mind, surpasses the method of Napier, although a certain Scotchman, even in the year 1594, held out some promise of that wonderful canon in a letter to Tycho.”* That this correspondent was Dr John Craig cannot be doubted when the fact is coupled with what we have noticed above. Craig had long intended to pay Tycho a visit, as appears from his own account in the letter he wrote to that philosopher in 1589. He there states, that five years before, he made an attempt to reach Urani- bourg, but had been baffled by storms and the inhospitable rocks of Norway, and that ever since, being more and more attracted by the accounts brought by ambassadors and others, of Tycho’s fame, and the magnificent scale of his observatory, he had been longing to visit him. It is not at all unlikely, there- fore, that James VI., who in the year 1590 spent some days at Uranibourg before returning to Scotland, had been encouraged in the idea of paying his * Nihil autem supra Neperianam rationem esse puto: etsi quidem, Scotus quidam literis at Tychonem A. CIdIOxcIv scriptis jam spem fecit Canonis illius Mirifici. Petrus Cucerus, to whom the letter is addressed, a mathematician of Dantzick, and the master of the celebrated Hel- velius, was a favourite correspondent of Kepler’s. The volume in which the above occurs is Kep- lert Epistole, a splendid folio, published under the auspices of the Emperor Charles VI. by Mi- chael Gottlieb Hanschius. I was anxious to see this volume, but could find it nowhere in Scot- land, nor could I procure a copy from London. Dr Irving, however, obtained one from Germany, whichis now in the Advocates’ Library. Napier is particularly mentioned by the learned editor in his prefatory notice of great men,—“ Non hic reticenda est Jo. Neprert, Baronis Merchistonii Scoti, inventio Canonis Mirifict Logarithmorum,’—he mistakes, however, the import of Kepler's ex- pressions, the gloss on tne margin being Canon Mirificus an Nepperi ? But Kepler meant to imply no such doubt, as will afterwards appear from his own letter to Napier, which is not in this collection. NAPIER OF MERCHISTON. 365 respects to the philosopher from the suggestion of Dr Craig, who was so long about his person in a medical capacity, and ultimately at the head of his me- dical board. Craig, of course, seized the propitious opportunity of the royal progress, to visit his friend, and we may well imagine, that among the first to whom on his return to Scotland he narrated all that he had seen and heard at Huen, was John Napier. Something must have passed betwixt them as to the trigonometrical difficulties experienced by Tycho and his assistant Longomontanus, in the vast field of their researches; and Kep- ler was too well acquainted with the prince of Uranibourg, and his corre- spondence, not to be worthy of the fullest credit when he says, that Tycho’s friend in Scotland wrote him a promise of the Logarithms so early as 1594. We have looked in vain for that letter, which Kepler probably had only heard of, as he did not join Tycho until after the expulsion of the latter from his island in 1597.* Enough, however, is here afforded completely to refute the idea which some have adopted from the anecdote in Wood. If, on the return of Craig from Denmarkin 1590, Napier had actually framed his canon for the spe- cial purpose supposed, the boon would not have remained unheard of for more than twenty years ; and if the hint from Longomontanus was of a nature to lead thus suddenly to the discovery, surely the Danish philosopher might himself have made something of the matter when, in addition to his own idea, hereceived through Craig a new hint in the account of Napier’s success. The fact is, that no hints could so quickly generate the logarithms, the discovery of which was the fruit of most original, profound, and laborious abstraction. That our philosopher delay- * There is an anachronism committed, supra, p. 147. Kepler did not join Tycho until the expulsion of the latter from Uranibourg. But Longomontanus was with him there for eight years, and Dr Brewster (Life of Newton, p. 122,) is mistaken in supposing that he only joined him as a pupil at the time Kepler did. Of all Tycho’s pupils and assistants at Uranibourg, the most dis- tinguished was Longomontanus, the son of a labourer, and so called from his birth place in Ger- many. It was the affectation of the times to construct sonorous names from the birth-place ; such as, Fheticus, Dithmarthus, Regiomontanus. Kepler was sometimes called, for the same reason, Leomontanus. There is no notice in the works of Longomontanus that he had acquired the slightest foreknowledge of the Logarithms; and, according to Vossius and Montucla, he survived Napier for nearly thirty years, nor ever hinted such aclaim. The learned Thomas Smith notices the anecdote of Wood to reject it, and adds, in reference to Longomontanus, “ an vero quicquam simile aut quovis modo analogum, hac ex parte prestiterit celeberrimus ille Tychonis discipulus, alitér fame in se ex scriptis editis et inventis derivande cupidissimus, nullibi ab illo memoratum reperio. Inventum hoc prorsus mirabile czlesti ingenio Nepert unicé debetur.”— Vite Hrudissi- morum, &¢. 4 366 THE LIFE OF ed the publication long after he had achieved the conquest, may easily be ac- counted for both by the nature of the tables he had to construct, and of his own diffident and retiring disposition. Tycho Brahe did not live to obtain the benefit of a discovery which thus seems to have been first reported to himself on his throne of science. Soon after the date of that communication, his reverse of fortune occurred which so cruelly interrupted his studies. The death of his kind patron Frede- rick II. left him a prey to faction, and the grand master of the king’s house- hold was his enemy. The pretext of economy, a never-failing recourse of all rising factions, was listened to as a reason for breaking up the establish- ment at Huen. And Tycho was driven from Uranibourg, where for five and twenty years he had made acquaintance with the stars, and spread the light of science far and wide. He was deprived of the throne before which kings had bowed, and in his declining years was turned adrift with his fa- mily to seek an asylum elsewhere. The latest biographer of Newton has (most unjustly we think) bitterly reproached England for her treatment of her own philosopher. ‘“ Such disregard,” are his words, “ of the highest genius, dignified by the highest virtue, could have taken place only in England, and we should have ascribed it to the turbulence of the age in which he lived, had we not seen in the history of another century that the successive governments which preside over the destinies of our country, have never been able either to feel or to recognize the true nobility of genius.”* But England, who did not thus disgrace herself, would, in the worst fit of economy that ever afflicted her, have shrunk from treating Newton as Denmark treated Tycho. To the honour of Germany, Rodolph II. received the wanderer, and his faithful Longomontanus, at Prague, and re-established him in a faint reflection of his former state. It was under this emperor’s patronage that he received as a coadjutor the immortal Kepler, which might have con- soled him for the loss of Uranibourg. His health, however, was broken, and he died at the age of fifty-five, in the year 1601, when speculative and prac- * This severe sentence has a ludicrous effect when contrasted with the index of the very work in which it occurs. ‘“ Mr Newton, warden of the Mint, in 1695—appointed master of the Mint in 1699—elected associate of the Academy of Sciences in 1699—Member for Cambridge in 1701 —President of the Royal Society in 1703—Queen Anne confers upon him the honour of knight- hood in 1705—His death 1727—His body lies in state—He is buried in Westminster Abbey— A medal struck in honour of him—Roubilliac’s full length statue of him erected in Cambridge.” —Dr Brewster's Life of Newton. NAPIER OF MERCHISTON. 367 tical science were both on the very eve of obtaining the two greatest impulses they ever received, Logarithms and the Telescope. In reference to the state of science, no less than to the scientific fame of this country, Napier’s discovery was admirably timed. Kepler was in the act of examining the orbits of the planets, to the destruction of Tycho’s system, but at the expense of calculations, which, had the Scotch philosopher not come to his aid, would have killed him. Galileo had just turned the telescope to the stars, and disclosed a scene which added so vastly to the field of inquiry that trigonometry was paralysed, and could grasp the heavens no longer. But be- fore proceeding with the history of the Canon Mirificus, we must pause to do homage to him, “ the starry Galileo,” for he was suffering the persecution of the Romish Church at the very time when Napier’s treatise against Antichrist was creating a sensation on the continent; and the treatment he met with affords another contradiction to Brewster’s condemnation of England. He was born at Pisa in the year 1564, fourteen years later than Napier. His father was a Florentine nobleman, highly distinguished for his taste and accomplishments, and rather averse to the philosophical propensities which dis- played themselves in his son at an early age. But Galileo overcame every ob- stacle, and devoted his whole mind to physical research. His open hostility to the schoolmen, necessarily placed him in imminent danger at an early period of his career, and he was soon forced to take refuge in Padua from the bigotted faction of his country. There, in 1592, he obtained the professorship of mathe- matics, which he graced for nearly twenty years with a reputation constantly in- creasing, until Cosmo II., the son and successor of Ferdinand his original patron, courted his return to Pisa, and placed him at the head of the science of his country with every mark of honour and means of independence. Galileo had then ample opportunity to apply the whole powers of his penetrating obser- vation against the ancient systems, which he fearlessly derided. While a storm was gathering around this determined enemy of Aristotle and Ptolemy, Pro- vidence placed in his hand that discovery which became the acme at once of his triumph and his persecution. Some superficial observer had detected the fact, that a certain combination of glasses magnified objects seen through them. Galileo, who in that sickly age of philosophy already reasoned like a Baconian, and was the most penetrating of experimentalists, brought the popular fact un- der the question of his severest scrutiny, and extorted from nature her secret of the telescope. It would prolong his biography beyond the purpose of this sktech, 368 THE LIFE OF to follow minutely the triumph. His own account, so graphically given in the Sidereus Nuncius, of his gradual approach, through a long chain of optical experiment, from the fact he scrutinized to the complete instrument, the as- tounding success of its first application, and his details, con amore, of those ethereal visions of immortal light, gradually disclosing their unheard of eco- nomy, complete the most splendid picture in the history of applicate science, and compose a narrative more fascinating than an eastern tale, and more ex- citing than the fictions of romance. In our long enlightened age, we can scarcely appreciate the triumph of Galileo. He obtained the homage of kings, and became domesticated in palaces. ‘The most important result, and to him infi- nitely above the favour of princes, was the visible demonstration which the telescope afforded of the truth of the Copernican system. Not only by unfold- ing the immensity of creation, and the lavish economy of the heavenly bodies, were the pretensions of our own planet to repose in the centre of such a sys- tem rendered palpably ridiculous, but facts were disclosed of a nature to force conviction upon the most unwilling. It had been objected to Copernicus, that, if his theory of the heavenly bodies were correct, some of the planets, especially Venus, while describing an orbit round the sun, and betwixt that luminary and the earth, would present phases like the moon. Copernicus met the objection in the boldest manner. He saw the necessity of the deduction, and maintained, that were it not for the minute sparkle of the distant planet, her phases would be visible. Galileo, by the most persevering observations, found the fact to be precisely as predicted. He might have despaired had he only discovered the satellites of Jupiter, and we may imagine the feverish anxiety with which he sought to redeem this special pledge of Tycho’s prede- cessor, and almost dreaded the result of each new developement. The predic- tion of Copernicus was so bold, the field of research so vast, that to doubt and tremble for the result might be forgiven in the most ardent and indomitable of his disciples. At VENUus etherios inter Dea candida nimbos Dona ferens aderat. Ille Dez donis et tanto letus honore Expleri nequit, atque oculos per singula volvit, Miraturque ! From night to night, a season to him of more than diurnal excitement or meridian splendour, he followed with sleepless assiduity the bright steps of the beautiful goddess, detected, with trembling devotion, the coy planet in all her NAPIER OF MERCHISTON. 369 phases, and he remembered his master. “ Oh Nicholas Copernicus ' he ex- claimed, “ how would’st thou have exulted at this evidence of thy truth !” The life of Galileo had its phases like the planets. The terrors of the In- quisition were then more than a match for philosophers and princes, and it was not likely that discoveries which so greatly increased the rising tide of universal reformation, would escape the keenest persecution of the church. The system of Copernicus was, comparatively, little dreaded by the Jesuits until they found it so powerfully pressed upon the conviction even of the vul- gar, by the most fascinating application to their senses. It was not at once, however, that they could attempt to crush a philosopher, whose lofty genius and unprecedented success had drawn around him a brilliant and powerfulcircle, which he daily enlightened. But the extreme popularity of his dialogues on the rival systems, and the ridicule with which they overwhelmed the adversa- ries of Copernicus, roused the Inquisition. Not all the power of his friends could shield the aged philosopher ; and it is sad to think, that such a name as Galileo’s should be connected with the darkest secrets of the Inquisition. Some phrases in the sentence pronounced against him create a suspicion, that the holy tribunal had privately inflicted torture upon the noble Florentine for the purpose of reducing his spirit to obedience. ‘The details of this disgusting judi- cial process against one of the greatest benefactors of science are too painful to be dwelt upon. The result was the celebrated abjuration, which the church has put on record to its own eternal disgrace as a judicial establishment. The composition cf that oath dictated by the Inquisition,—its blasphemous energy of style,—the solemn ignorance of its details,—the very first words, “ I, Galileo Galilei, aged seventy years, being brought personally to judgment, and kneeling before you most eminent, and most reverend Lords Cardinals, general inquisitors of the universal Christian republic against heretical depra- vity,” &c.—the seven cardinals signing their own immortal infamy,—compose the severest satire ever penned against the Church of Rome. Why have all the distinguished philosophers of our own times not done justice to the memory of the illustrious Galileo, who in his will so pathetically and con- fidently bequeathed his fame to after ages ? Delambre has hastily censured him for want of sincerity ; and Brewster, a disciple of light, has arraigned him at the bar of public opinion with more solemn and elaborate injustice, “ On the 22d June 1633,” says Newton’s biographer, “ Galileo signed an ab- juration humiliating to himself, and degrading to philosophy. At the age of 3A 370 THE LIFE OF seventy, on his bended knees, and with his right hand resting on the Holy Evangelists, did this patriarch of science avow his present and past belief in all the dogmas of the Romish Church, abandon as false and heretical the doc- trine of the earth’s motion, and of the sun’s immobility, and pledge himself to denounce to the Inquisition any other person who was even suspected of he- resy. He abjured, cursed, and detested those eternal and immutable truths, which the Almighty had permitted him to be the first to establish. What a mortifying picture of moral depravity and intellectual weakness ! If the un- holy zeal of the Assembly of Cardinals has been branded with infamy, what must we think of the venerable sage, whose gray hairs were entwined with the chaplet of immortality, quailing under the fear of man, and sacrificing the convictions of his conscience, and the deductions of his reason, at the altar of a base superstition ? Had Galileo but added the courage of the martyr to the wisdom of the sage,—had he carried the glance of his indignant eye round the circle of his judges,*—had he lifted his hands to Heaven, and called the living God to witness the truth and immutability of his opinions, the bigotry of his enemies would have been disarmed, and science would have enjoyed a memorable triumph.” It is impossible to admit that this is either true to the character, or just to the conduct, of Galileo. The most gentle and least pugnacious are fond to picture lofty conceptions of indomitable bearing, which yet might desert the stoutest in the hour of need; and from the bosom of security it is not difficult to pronounce an eloquent anathema against extorted apostacy, and to flatter ourselves that we would have remained unmoved amid terrors, and mute under torture. But it should not be forgotten that the spirit of Galileo, though shattered by the weight of seventy years, and many a physical infirmity, still required the earnest and anxious persuasions of judicious friends to subdue it. Alas! for such weapons against the most holy In- quisition, as.the trembling invocation of aged hands, and the indignant glance of an old man’s eye, whose vision had been already sacrificed at the fountains * By this time Galileo was nearly blind from the use of his telescope, and not long afterwards became totally blind. Newton’s biographer, (p. 139,) ingrafts a sentiment of his own upon the eloquence of M. Bailly ; “ C’est un singulier spectacle que celui d’un yieillard couvert de cheveux blanchis par étude, par ses veilles, par ses bienfaits envers les hommes, A genoux devant le livre le plus respectable, abjurant la vérité aux yeux de I’Italie qu'il avoit éclairée, malgré le temoinage de sa propre conscience, et contre la nature entiére qui manifeste cette vérité.” But Bailly con- demns the judges, not the pe eter otass Moderne, Tome ii. p- 1380. NAPIER OF MERCHISTON. 371 of light. There is an obvious fallacy, too, which pervades the moral senti- ment of the author quoted, when he bewails the absence of the “ courage of a martyr from the conduct of the sage.” To expire calmly under torture, as an evidence of believing, has substantial meaning in the cause where, farth is life, though even in that cause it is not for mortal man to condemn the frailty of the flesh shrinking under terror or torture. But when the idea-is extend- ed beyond the case of adherence to the Christian creed, the necessity or beauty of martyrdom assumes a very different, perhaps an equivocal aspect. Unprotected by mortal power, unsustained by those immortal visions which the martyrs of the church found mightier than the help of man, was that il- lustrious philosopher, bending under a load of infirmities, brought before a tribunal whose actual terrors romance cannot exaggerate. Had he called God to witness the truth of demonstration, and sacrificed his life “ at the altar of a base superstition,” where would have been the triumph to science ? the melancholy scene would not have added an atom to the evidence of physical truths—not a convert to the system of Copernicus. If, in the particular in- stance, Galileo did not display the courage of the martyr, it cannot be de- nied that he eminently possessed the daring of a man. In character and temperament he resembled his friend Kepler, and it was the persevering and satirical independence of his tone, which ultimately brought him un- der the ban of the Inquisition. There cannot be a stronger proof of his spirit than the exclamation with which, old, and feeble, and subdued as he was, he accompanied his extorted oath. To him the whole pa- geantry of the abjuration appeared a ludicrous satire on his judges. Tho- roughly imbued with a feeling of the necessity of demonstrated truth, to him it was the same to be compelled to call God to witness against any self- evident proposition, as that the system of Copernicus was false; and toa mind, accustomed like his to mount so easily from proposition to proposition in the ascending scale of mathematical certainty, it was not more absurd to forswear that two and two make four, than those eternal truths which the very evidence of his senses had confirmed. Regarding the ignorant energy of the abjuration dictated to him, as supremely ridiculous, the venerable phi- losopher, when rising from the kneeling attitude, struck the earth with his foot, and murmured to his friends,—“ J¢ moves, nevertheless.” Bailly, in his eloquent history of astronomy, observes, that, with the 372 THE LIFE OF aid of the telescope, man had penetrated far into space, and yet that nature, in opening so many paths to truth, would have done nothing for mankind, had she not also afforded the means of economising time; that physical researches increasing in multitude, depth, and nicety, required the aid of nu- merical calculation to an infinite extent, the labour of which left philosophers with broken spirits and a prey to disgusts; that the same calculations which now occupy a month, were then the labour of three years, and that Kepler alone was unsubdued by the tyranny of logistic. But, he adds, “ Le baron de Neper, Ecossois, montra des routes plus faciles, et ila rendu son nom immor- tel, comme celui des bienfaiteurs du monde.” While Denmark had Tycho, France Vieta, Germany Kepler, and Italy Galileo, Britain was absolutely ray- less by comparison ; for Roger Bacon belonged to an obsolete era, Francis Bacon was yet a statesman, and the works of Harriot were not published until many years after the death of Napier. ‘The moment, however, it came to be understood, that, by the exertions of a single individual, NUMBERS were revo- lutionized,—and in their loftiest department the science of trigonometry,—all eyes were turned to Scotland. Nor is this a partial and local sentiment. From Bailly we have drawn a description of the painful struggles of science while her best wing was fettered, and from Montucla we shall cull a picture of her daring flight the moment that wing was free. “ Among the ages which have successively contributed to the advancement of the sciences, that which is now fleeting away (the 18th century) holds undoubt- edly the highest rank, and probably no succeeding age will deprive it of that ele- vation. Far be it from us to fix a limit to the human mind. Who knows the last boundary of knowledge, or where she must stay her step! Day after day uttereth knowledge, and to disregard the progress of discovery would be to withhold unjustly the tribute that is due to our illustrious contemporaries. Still, when we regard the wonderful flight which the sciences, and especially the mathematics, took in the seventeenth century, we must admit, that, what- ever perfection they may receive from succeeding ages, a vast portion even of their glory will ever reflect back upon the age which so propitiously com- menced the career. How brilliant is the spectacle which that era presents ! How fascinating and admirable to the philosophic eye! If we turn to the pure mathematics, we find in the first years of that century LOGARITHMs, that invention so ingenious, and whose utility surpasses its ingenuity. We per- ceive the algebraic analysis, or the resolution of equations, greatly advanced NAPIER OF MERCHISTON. 373 by the discoveries of Harriot, Descartes, Newton, Halley. A new geome- try, generated in the hands of Cavalleri, and cultivated by others, aspires to researches far beyond the penetration of antiquity. Descartes in the mean- while explores another path, and, applying the analysis to his geometry, gives the theory of curves an extension and play hitherto unknown, and invents a variety of methods of solving with perfect certainty the most difficult problems in that branch of science. Fermat, the rival and contemporary of Descartes, pursues the same career, and promulgates inventions in which the germ of the new calculus is greatly developed. Wallis, Barrow, Gregory, enrich geometry with a multitude of new methods and discoveries. Newton at length gives birth to that sublime geometry, compared with which the labours that paved the way were as trifles, and has furnished the only key to those difficult investigations which occupy the geometers and naturalists of the pre- sent day. If we carry our view to the mixed mathematics, we will be no less delighted with the prospect of their acceleration. Mechanics present to us the laws of motion and its communication, the laws of the acceleration of heavy bodies, of the path of projectiles, of the motion and reciprocal action of fluids. We see them enriched by several profound theories,—such as the centre of oscillation, the resistance of fluids, the doctrine of central forces, &c. At the same time the progress of optics is proceeding with equal brilliancy, the laws of vision and refraction unfolded, and a new science rises from that foundation. The telescope and microscope afford aids unknown to antiquity, —the rainbow is submitted to reason, —light is analyzed, and the various refrangibility of colours detected, —the reflecting telescope is conceived and constructed with success,—Astronomy, in fine, presents us at once with the discovery of the actual forms of the planetary orbits, and of the laws which preside over the celestial motions. Soon after the in- vention of the telescope, we see astronomers as it were soaring into space,— descrying the spots on the sun,—the motion of that luminary round its axis, —the phases of Venus and Mercury,—the little planets which attend like moons the steps of Jupiter, and of Saturn with his marvellous ring,—pheno- mena which shed a meridian light upon the true system of the universe. Upon these observations geography is entirely remodelled,—the earth is mea- sured with an accuracy far surpassing the measurement of the ancients, and her true form is ascertained,—the truth of Kepler’s observations is demon- strated by means of a profound application of geometry and mechanics to the 374 THE LIFE OF motion of the heavenly bodies,—the comet is controlled into a planet, and the career of that rare apparition submitted to calculation. The moon, so long rebellious to astronomy, is captive at length, and her eccentricities account- ed for. And at last, from the hands of the immortal Newton, we receive the system of physical astronomy, the master-piece of geometry and mechanics, accumulating daily new confirmation from the combined labours of geometri- cians and observers.” * With how few of the conquests here enumerated is that of Napier not identified. To be named first among the great landmarks of an era of calculation, is certainly due to him, because the mechanical discovery of the telescope, though applied a few years before the promulgation of Logarithms, has no pretensions to such intellectual claims. The century which com- menced with the Canon Mirificus Logarithmorum, and was followed by the Novum Organum Scientiarum, deserved to be closed by the Princi- pia Mathematica ; and thus it is that Napier, and Bacon, and Newton, creat- ed the transcendant era of science, and, to use a congenial phrase, brought up so gloriously the lee-way of old England. We now present the reader with a fac-simile of a title-page fraught with glad tidings ; and we do so, not so much on account of the beauty of the design, as be- cause no page of profane history can be more interesting, though the volume is so rare that the most illustrious commentators upon Logarithms have never seen it.t But all the power of such minds as Montucla’s and Delambre’s has been called into action in order to analyze the structure, to test the intellectual value, and to expound the theory of this work, while other authors, of no mean repute in the school of Newton, have treated of it in a manner which shows how deeply rooted the theory is, and how it comes into operation with all the mysterious powers of the higher calculus. In order to see that it would be vain and presumptuous for any one, not far above mediocrity in mathematics, to attempt a scientific analysis of the invention, it is only necessary to glance at such works, and also at the six enormous volumes entitled “ Scriptores Lo- garithmici,” which form the scientific collections of Baron Maseres.

DELAMBRE has writ- ten that chapter of our philosopher’s life. But to translate in these pages the labours of Delambre, whose elegance and depth have left nothing to desire, and would suffer from abridgement, would be of no use to readers who can relish his writings, and unintelligible to all the rest. Science has a language that is sealed to most people, though indispensable, from the very relief it affords, to philosophers. Delambre himself might shrink at the idea of extracting the secret of Logarithms from numbers, in the chaotic state in which Napier found them; and of constructing the tables, and demon- strating them to the world with the imperfect mathematical resources and language of his day. It was like separating the light from darkness, and Newton was not compelled envisager the subjects from which he drew his immortality, under the difficulties that beset the path of Napier. A complete exposition of Logarithms, therefore, is not to be attempted except in the mo- dern language of science ; and we cannot pay our philosopher a higher com- pliment than to say, that, until that language came to be developed, with all the powers and properties of numbers which it alone can fully disclose, no complete exposition of his work could be obtained. Delambre, therefore, and all who are capable of the investigation, have viewed the invention under the penetrating lights of the New Geometry, and draw this inference as to the author’s mind, “ Tous ces moyens étaient connus de Néper, quoiqu’il n’elt pas ces expressions algébriques ; ce calcul est la traduction de ses raisonnemens ; een est le fond, si ce n’est pas la forme tout a fait; i] ne négligeait que des quantites reconnues insensibles ; la construction de ses tables preparatoires est donc démontrée.” But the general reader, however anxious to form a just estimate of Na- pier’s achievement, would scarcely thank us for an analysis which requires to be expounded as follows :—‘ Néper n’emploie pas ces expressions, que étal nnues ; mais soit R le rayon; les limites seront 2 fe n étaient pas co 3 yon ; Sr F . bos R?—RsnA “R—sin A R et R — sin A; la moyenne arithmétique oa to = R2—RsnA+RsnA—sin?

Referring, therefore, those who wish to fathom the subject, to the works quoted below,* we shall discharge our biographical duty by concluding these Memoirs with a history of the reception of Loga- rithms, a defence of the author’s intellectual rights, and some popular views and original information respecting his mathematical studies. No sooner did the Canon Mirificus appear than it found, like the Plain Dis- covery, an able and enthusiastic translator. England did not at the time possess any philosopher whose capacities entitled him to rank in science with such as Kepler and Galileo, or whose labours were so pre-eminent as to attract the eyes of the continent to this island. Scotland was out of the question, where, of those times, generally speaking, he is the most worthy of recollection who was least identified with judicial, feudal, or fanatical murder. But in the sister kingdom, there were one or two conspicuous, in their own country at least, for the highest order of that species of talent, which is rather characterized by acuteness in derivative speculations than eminent success in original discoveries ; men, in short, who most deservedly obtain a place in the history of science, but chiefly in connection with some greater genius than their own, to whom they mini- ster. It marks at once the majestic position of our philosopher when we say, that no sooner was his orbit discovered in the system than he was observed to be followed by two such satellites, in Kdward Wright and Henry Briggs, who at the time were Tycho and Kepler to England. Of these, the former ardently set himself to translate the work into English, and the latter became the most enthusiastic co-operator of the author in computing improved tables. NAVIGATION, like trigonometry, had arrived at the period of its history, beyond which it couid not advance without some revolution in science. That scientific art had indeed done wonders without Logarithms; but the very extent of its conquests required such aid to secure them, and bring out all their value. It was only about the middle of the fifteenth century that ma- * For profound views of the theory of Logarithms, consult the Histories of Astronomy and Mathematics by Montucla and Delambre, already quoted; the History of Logarithms, by Dr Charles Hutton, prefixed to his edition of Sherwin’s Tables; Dr Wallis’s Treatise of Algebra; a Treatise of Fluxions, by Colin Maclaurin, A. M.; account of Napier’s Writings and Inventions by Dr Minto ; appendix to a Treatise on Plane and Spherical Trigonometry by Robert Wood- house, Fellow of Caius College, Cambridge; and above all, Baron Maseres’ Scriptores Logarith- mici, in six volumes quarto. ‘The editio princeps of the Canon is reprinted in the Maseres col- lection, but without the engraved title-page. 3B 378 THE LIFE OF riners began to feel themselves at home upon the deep, when, in addition to the compass, they could derive assistance from mathematical science; and it is melancholy to observe that the country which ranks first in the history of navigation, and once stood so high in the chivalry of Europe, is now the lowest in the scale. Portugal, by her series of unrivalled discoveries, marks the com- mencement of the grand era of nautical science ; and when that nation pointed out the New World, and the passage to India by the Cape of Good Hope, she gave navigation enough to do. One indispensable requisite, in order to secure the benefit of such discoveries, was those scientific sea-maps, or charts as they are called, without which the compass itself would be of little value. These had been constructed upon a very imperfect principle, until towards the close of the sixteenth century, when the plane chart began to be superseded by the improvement of Gerard Mercator, the well-known geographer of the Low Countries. In the old sea-charts, the nearer the degrees of longitude ap- proach the pole the more they were increased beyond their just proportion, while the degrees of latitude remained the same ; and thus false bearings were obtained in nautical geography, and errors pervaded the system. The pro- position of Mercator, which has immortalized his name, was to rectify these evils, by augmenting the parallels of latitude in their approach to the pole, in the same proportion as those of the longitude ; and he published a chart, con- structed upon these principles, about the year 1569. But Montucla, in his History of Navigation, says, that Mercator, although he furnished the idea, was not aware of, and could not demonstrate, the scientific laws of his own scheme, and that this honour was reserved for our countryman, Edward Wright, who was the first to do so, in a treatise printed in London in the year 1599, and entitled, “ Certain errors in navigation detected and corrected.” Thus Wright is the person to whom, scientifically speaking, Mercator’s sail- ing belongs; and this seems to have been the estimation in which he was held by his contemporaries. One of Napier’s poetical eulogists, who designs himself, “ the unfained lover and admirer of his art and matchlesse vertue, John Davies of Hereford,” when praising the Canon Mirificus, thus suddenly and facetiously apostrophizes its translator :— Waricut !—ship-wright ? no; ship-wright, or righter then When wrong she goes,—lo! this, with ease, will make Thy rules to make the ship run rightly, when She thwarts the main for praise or profit’s sake. 4 NAPIER OF MERCHISTON. 379 We have called Wright the Tycho of England, because in astronomical obser- vations and instruments he outwent all his countrymen. He was ten years younger than Napier, and, after studying at Cambridge, devoted himself en- tirely to navigation. For the purpose of perfecting himself in that art he ac- companied George Earl of Cumberland in his expedition to the Azores, and the fruits of his enterprise was the treatise published in 1599. He was dis- tinguished for his tables of latitudes, his sea-rings, his great quadrant, and his sea-quadrant, besides other ingenious astronomical contrivances. He was also appointed instructor in mathematics to Prince Henry, the young Mar- cellus of England, whose hopeful promise perished so soon. Montucla derives from Sir Edward Sherburne some details of the life of Wright, and adds, “ Il fut enfin (ce que Sherburn a ignoré) un des premiers promoteurs de la theorie et de la pratique des Logarithmes, avec Briggs ; car il en avoit construit des tables. Mais sa mort, arrivée vers 1618 ou 1620, l’empécha de les publiés. Ce fut son fils qui les mit au jour en 1621.” But we must, in our turn, cor- rect Montucla. Not only did Edward Wright construct tables connected with Logarithms, but he translated the canon into English the moment it ap- peared, and his exertions to aid the promulgation seem to have killed him, for he died in the year 1615. So rare are these original editions, that of the two greatest historians of Logarithms, Delambre never saw the Latin edition, and Montucla never heard of the English. But the interest in the English edition is greatly increased when we under- stand that it passed through Napier’s hands to the press. It appears that some patron of letters had recommended Wright to translate the Canon the moment it was published, who was himself instantly struck with the prospect of the revolution it would effect in navigation, of which, at the time, he unquestionably occupied the cathedra. Ina preface to Wright’s translation we are informed by his son, that he “ gave much commendation to this work, and often in my hear- ing, as of very great use for mariners.” This must have been in the first year of its publication, for in that or the following Wright sent Napier the translation for revisal, “‘ and,” says his son, “shortly after he had it returned out of Scotland, it pleased God to call him away afore he could publish it.”* The task accordingly devolved upon Samuel Wright, with the assistance of Henry Briggs, and the volume was printed in London by Nicholas Okes in 1616. That the most * There is a Latin memoir of him in the annals of Gonyile and Caius College, Cambridge, which bears, “ This year, 1615, died at London, Edward Wright of Garveston in Norfolk, for- 380 THE LIFE OF important practical application of Logarithms in human affairs was instantly appreciated appears from the first page of this translation. “ To the Right Honourable and Right Worshipful Company of Merchants of London, trading to the East Indies, Samuel Wright wisheth all prosperity in this life, and happiness in the life to come. Your favours towards my deceased father, and your imployment of him in business of this nature, but chiefly your continual imployment of so many mariners, in so many goodly and costly ships, in long and dangerous voyages, for whose use (though many other ways profitable) this little book is chiefly behooveful, may challenge an interest in these his labours. This book is noble by birth, as being descended from a noble pa- rent, and not ignoble by education, having learned to speak English of my late father,” &c. Probably it would be left to Napier to translate his own letter to Prince Charles, and the address to his “ charissimt mathematum cultores ;? and we shall present them to the reader in the English version, which, though not equal in purity of style to the Latin, is quaint and characteristic. As if he had never lost sight of Archimedes for a prototype, * our philosopher addresses the volume. * 'To the Most Noble and Hopeful Prince CHARLES, only son of the High and Mighty James, King of Great Britain, France, and Ireland ; Prince of Wales, Duke of York and Rothesay; Great Steward of Scotland, and Lord of the Islands. “ Most NOBLE PRINCE. Seeing there is neither study nor any kind of learn- ing that doth more acuate and stir up generous and heroical wits to excellent merly a fellow of this college; a man respected by all for the integrity and simplicity of his man- ners, and also famous for his skill in the mathematical sciences.” After narrating his various scientific labours, the memoir adds, “ A little before his death he employed himself about an Eng- lish translation of the book of Logarithms, then lately found out by the Honourable Baron Napier, a Scotchman, who had a great affection for him. This posthumous work of his was published soon after by his only son Samuel Wright, who was also a scholar of this college. He had form- ed many other useful designs, but was hindered by death from bringing them to perfection. Of him it may be truly said, that he studied more to serve the public than himself; and though he was rich in fame, and in the promises of the great, yet he died poor, to the scandal of an ungrate- ful age.” —See Hutton’s Hist. of Logarithms, and Wilson's Hist. of Navigation. * Archimedes is always said to have been a relation of his own Sovereign, Hiero King of Sy- racuse, and he addressed the Arenarius to Prince Gelo, that monarch’s eldest son.

Why then may not this my new invention (seeing it abhorreth blunt and base na- tures,) seek and fly unto your Highness’ most noble disposition and patronage ? and especially seeing this new course of LOGARITHMsS doth clean take away all the difficulty that heretofore hath been in mathematicall calculations, (which otherwise might have been distastful to your worthy towardness,) and is so fitted to help the weakness of memory, that by means thereof it is easy to resolve more mathematical questions in one hour’s space, than otherwise by that wonted and commonly received manner of sines, tangents, and secants, can be done even in a whole day. And, therefore, this invention (I hope) will be so much the more acceptable to your Highness, as it yieldeth a more easy and speedy way of accompt. For what can be more delightful and more ex- cellent in any kind of learning than to dispatch honourable and profound matters, exactly, readily, and without loss of either time or labour. I crave, therefore, most gracious Prince, that you would, according to your gentleness, accept of this gift, though small and far beneath the height of your deserv- ings and worth, as a pledge and token of my humble service. Which, if I understand you do, you shall, even in this regard only, encourage me, that am now almost spent with sickness, shortly to attempt other matters perhaps greater than these, and more worthy so great a Prince. In the mean while, the Supreme King of Kings, and Lord of Lords, long defend and preserve to us the great lights of Great Britain, your renowned parents, and yourself, the noble branch of so noble a stem, and the hope of our future tranquility. To Him be given all honour and glory. “ Your Highness’ most devoted Servant, * JOHN NEPAIR.” This epistle dedicatory is followed by the author’s very interesting preface. “ Seeing there is nothing, (right well beloved students in the mathematics,) sentative of Margaret, second daughter of Duncan Earl of Levenax ; and the monarch stood in precisely the same relationship (through his father Henry Darnly,) to Elizabeth, Earl Duncan’s third daughter. 382 THE LIFE OF that is so troublesome to mathematical practise, nor that doth more molest and hinder calculations, than the multiplications, divisions, square and cubical extractions of great numbers, which besides the tedious expence of time, are for the most part subject to many slippery errors, I began, therefore, to con- sider in my mind, by what certain and ready art I might remove those hin- drances. And having thought upon many things to this purpose, I found at length some excellent brief rules to be treated of perhaps hereafter: But amongst all, none more profitable than this, which together with the hard and tedious multiplications, divisions, and extractions of roots, doth also cast away even the very numbers themselves that are to be multiplied, divided, and re- solved into roots, and putteth other numbers in their place which perform as much as they can do, only by addition and substraction, division by two, or division by three. * Which secret invention being, (as all other good things are,) so much the better as it shall be the more common, I thought good here- tofore, to set forth in Latin for the public use of mathematicians. But now, some of our countrymen in this island, well affected to these studies, and the more public good, procured a most learned mathematician to translate the same into our vulgar English tongue, who after he had finished it, sent a copy of it to me, to be seen and considered on by myself. I having most willingly and gladly done the same, find it to be most exact and precisely conformable to my mind and the original. Therefore it may please you who are inclined to these studies, to receive it from me and the translator, with as much good will as we recommend it unto you.—Lare thee well.” The philosopher, in the original, adds a Latin verse of his own, which is not given in the translation.

Of the English edition I have only seen one copy, that in possession of the Lord Napier. NAPIER OF MERCHISTON. 383 CHAPTER X. Dr CHARLES HUTTON, in an able history of Logarithms attached to the best English tables, has done great injustice to Napier, both negative and positive. He has, in the first place, not sufficiently distinguished the inven- tion from every other analogous idea that had been previously entertained of progressions, nor shown how undivided is the honour which belongs to Scotland. On the other hand, he has attempted to deprive Napier of the praise of having perfected the system he created ; and, what is worse, while erroneously referring that merit to another, he has falsely accused our philo- sopher,—the lofty cast of whose mind was only equalled by its unpretending modesty,—of a mean attempt to appropriate to himself what was not his due. It would be an omission on the part of his biographer not to place these mat- ters in their proper light, though the character and genius of Napier stand far above such attacks or the necessity of a defence. His character, in- deed, is remarkable for purity in the rudest age of his country; he was in- capable of meanness, nor would I have been much inclined to notice the groundless insinuations of a modern writer, who knew nothing of Napier’s private history, were it not that those insinuations disturb the beautiful pic- ture of friendship and enthusiastic co-operation betwixt Napier and Henry Briggs, which does so much honour to science. It is well-known to those who have examined the matter scientifically, that Napier viewed and worked his subject under the most difficult aspects, and in the most laborious manner. He had none of those resources, which, if the task were still to be performed, the most fearless calculator of our own times would 384: THE LIFE OF be too happy to call to his aid. He had clearly in his mind, however, many of the most valuable analytical principles of a school then unfounded, the school of Newton; and he caused them to bear fruit, without possessing the new modes of analytical inquiry, in the progress of whose subsequent develope- ment those very. principles became disclosed to others. This is implied in the words of admiration bestowed upon him by so illustrious a foreigner as De- lambre :—“ All these means were known to Napier, although he had not the algebraic expressions; he drew his calculus from the resources of his own mind.” Napier’s innate algebraic power is that which eminently distinguishes him above all the great calculators of his day ; the consequence is, that he produced the Lo- garithms before algebraic analysis reached that point in its progress to which the discovery properly belonged; and we can at the same time detect, in his modes of operation and train of thought, the most striking characteristics _of Newton’s mind. “ At a period,” says Playfair, speaking of Napier, “ when the nature of series, and when every other resource of which he could avail himself, were so little known, his success argues a depth and originality of thought, which I am persuaded have rarely been surpassed.” Thus his in- vention stands unquestionably more isolated in its glory, and more the un- divided property of one individual, than any other with which it can be com- pared. Now, Dr Hutton, while he states the properties of progressions, which are the fundamental principles of the system of Logarithms, in a very clear and distinct manner, has at the same time so framed his exposition as to lead any reader, who went no further than this author, to suppose that Napier shared the merit with many others, and only surpassed them in this, that to him “ the _world is indebted for the first publication of Logarithms.” The very able history of them, in which so much at least has been admitted, is in this country perhaps more under the eye of students than any other, and I shall quote the passages to which I allude. “ Incessant endeavours at length produced the happy invention of Logarithms, which are of direct and universal application to all numbers abstractedly considered, being derived from a property inherent in themselves. This property may be considered either as the relation be- tween a geometrical series of terms and a corresponding arithmetical one, or as the relation between ratios and the measures of ratios; which comes to much the same thing, they having been conceived in one of these ways by some of NAPIER OF MERCHISTON. 385 the writers on this subject, and in the other by the rest of them, as well as in both ways at different times by the same writer. A summary idea of this property, and of the probable reflections made on it by the first writers * on Logarithms, may be to the following effect. The learned calculators about the close of the 16th and beginning of the 17th century, finding the operations of multiplication and division by very long numbers of 7 or 8 places of figures, which they had frequently occasion to perform in solving problems relating to geography and astronomy, to be exceedingly troublesome, set them- selves to consider whether it was not possible to find some method of lessening this labour, by substituting other easier operations in their stead. In pursuit of this object they reflected that, since in every multiplication by a whole num- ber, the ratio or proportion of the product to the multiplicand is the same as the ratio of the multiplier to unity, it will follow that the ratio of the product to unity (which, according to Euclid’s definition of compound ratios, is com- pounded of the ratios of the said product to the multiplicand and of the mul- tiplier to unity,) must be equal to the sum of the two ratios of the multiplier to unity, and of the multiplicand to unity. Consequently, if they could find a set of artificial numbers that should be the representatives of, or should be propor- tional to, the ratios of all sorts of numbers to unity, the addition of the two artificial numbers that should represent the ratios of any multiplier and mul- tiplicand to unity, would answer to the multiplication of the said multiplicand by the said multiplier, or the sum arising from the addition of the said re- presentative numbers, would be the representative number of the ratio of the product to unity ; and consequently the natural number to which it should be found, in the table of the said artificial or representative numbers, that the said sum belonged, would be the product of the said multiplicand and multi- plier. Having settled this principle as the foundation of their wished-for method of abridging the labour of calculations, they resolved to compose a table of such artificial numbers, or numbers that should be representatives of, or proportional to, the ratios of all the common or natural numbers to unity. The first observation that naturally occurred to them in the pursuit of this scheme was, that, whatever artificial numbers should be chosen to represent the ratios of other whole numbers to unity, the ratio of equality, or of unity * There were no writers on Logarithms, ewcept Napier, until the Canon of Logarithms was published. There were plenty of writers on Logarithms after that, and, according to Dr Hutton, these learned calculators then set themselves to discover the Logarithms. 3 C 386 THE LIFE OF to unity, must be represented by 0; because that ratio has properly no mag- nitude, since, when it is added to, or subtracted from, any other ratio, it nei- ther increases nor diminishes it. The second observation that occurred to them was, that any number whatever might be chosen at pleasure for the re- presentative of the ratio of any given natural number to unity; but that, when once such choice was made, all the other representative numbers would be thereby determined, because they must be greater or less than that first repre- sentative number, in the same proportions in which the ratios represented by them, or the ratios of the corresponding natural numbers to unity, were greater or less than the ratio of the said given natural number to unity. Thus, either 1, or 2, or 3, &c. might be chosen for the representative of the ratio of 10 to 1. But, if 1 be chosen for it, the representatives of the ratios of 100 to 1 and 1000 to 1, which are double and triple of the ratio of 10 to,1, must be 2 and 3, and cannot be any other numbers ; and, if 2 be chosen for it, the representatives of the ratios of 100 to 1 and 1000 to 1 will be 4 and 6, and cannot be any other numbers ; and, if 3 be chosen for it, the representa- tives of the ratios of 100 to 1 and 1000 to 1 will be 6 and 9, and cannot be any other numbers; and soon. The third observation that occurred to them was, that, as these artificial numbers were representatives of, or proportional to, ratios of the natural numbers to unity, they must be expressions of the numbers of some smaller equal ratios that are contained in the said ratios. Thus, if 1 be taken for the representative of the ratio of 10 to 1, then 3, which is the representative of the ratio of 1000 to 1, will express the number of ratios of 10 to 1 that are contained in the ratio of 1000 to 1. And if, instead of 1, we make 10,000,000, or ten millions, the representative of the ratio of 10 to 1, (in which case 1 will be the representative of a very small ratio, or ratiuncula, which is only the ten-millionth part of the ratio of 10 to 1, or will be the representative of the 10,000,000th root of 10, or of the first or smallest of 9,999,999 mean proportionals interposed between 1 and 10), the represen- tative of the ratio of 1000 to 1, which will in this case be 30,000,000, will express the number of those ratzuncule, or small ratios of the 10,000,000th root of 10 to 1, which are contained in the said ratio of 1000 to 1. And the like may be shown of the representative of the ratio of any other number to unity. And therefore they thought these artificial numbers, which thus re- present, or are proportional to, the magnitudes of the ratios of the natural numbers to unity, might not improperly be called the LoGAaRITHMs of those NAPIER OF MERCHISTON. 387 ratios, since they express the numbers of smaller ratios of which they are composed. And then, for the sake of brevity, they called them the Logarithms of the said natural numbers themselves, which are the antecedents of the said ratios to unity, of which they are in truth the representatives. The fore- going method of considering this property, leads to much the same conclu- sions as the other way, in which the relations between a geometrical series of terms, and their exponents, or the terms of an arithmetical series, are contem- plated. In this latter way, it readily occurred that the addition of the terms of the arithmetical series corresponded to the multiplication of the terms of the geometrical series ; and that the arithmeticals would therefore form a set of artificial numbers, which, when arranged in tables with their geometricals, would answer the purposes desired, as has been explained above. From this property, by assuming four quantities, two of them as two terms in a geome- trical series, and the others as the two corresponding terms of the arithme- ticals, or artificials, or logarithms, it is evident that all the other terms of both the two series may thence be generated. And therefore there may be as many sets or scales of Logarithms as we please, since they depend entirely on the arbitrary assumption of the first two arithmeticals. And all possible natural numbers may be supposed to coincide with some of the terms of any geome- trical progression whatever, the Logarithms or arithmeticals determining which of the terms in that progression they are.” * The urgent demand for such a power, universally felt before its appearance, and the prior but obscure knowledge of certain principles connected with that power, may be admitted. But the error (which almost seems preme- ditated on the part of Dr Hutton) of the above exposition is, that the author has not chosen to discriminate betwixt the Archimedean principle as observed in the European school, and Napier’s great discovery, whose merit is to have passed a gulf which that principle had only reached, and which had hitherto ren- dered it an idle and fruitless speculation. He has traced, indeed, those long bar- ren ideas to their consummation ; but he has done so expressly, as if many had been at work for years to effect that conquest, and as if the whole system of Loga- rithms, and the very compounding of the term, did not exclusively belong to one individual. These deliberate speculations of “learned calculators about the close of the sixteenth and beginning of the seventeenth century,” are all creations of Dr Hutton’s jealousy. No one but Napier can be said to have thus set him- * Hutton’s History of Logarithms. 388 THE LIFE OF self to the task, and he alone it was who conceived a table which he at first called a table of artificcal numbers, and for which he afterwards composed the term Logarithms. We have elsewhere endeavoured to show precisely how far Archimedes went in the doctrine of numerical progressions. Now, until the Canon Mirificus appeared, and that was nearly two thousand years after him of Syracuse, these progressions, and the few speculations about them which occurred after the revival of letters, attracted no scientific admiration, and were unheard of, or uncared for in the world of letters. But when Napier had grafted that astonishing chapter of algebra upon the doctrine, men began to look about them to see if any one shared with him the glory of what was now felt to be an indispensable aid. Of all others, he who was most astonished, and who was most deserving to have anticipated Napier, was the immortal KEPLER. No greater philosopher ever arose in Germany, or one whose calculating powers were more gigantic and in more constant requisition. At this time he was far advanced on his path to fame, though considerably younger than Napier, and the diffidence of the Scotch philosopher, in withholding his great work from the public for so many years, gave the German ample time to have been thefirst “ to publish Logarithms,” had he formed any conception of such a canon. He was born in 1571, in a country where science was considered the most important department of human affairs, and found the richest patronage. Tycho, Galileo, and Kepler, all became pro- fessors and public astronomers while they were young men, and thus were not only conscious that the eyes of Europe were turned towards themselves, but being entirely devoted to such pursuits as a profession, and surrounded by their adoring students, and scientific domesticz, they possessed a never-failing stimu- lus, and constant practice. Kepler, like the two great contemporaries with whom he is always classed, was the scion of a noble family, which, however, was so reduced in circumstances, that nothing but his towering genius redeemed the young philosopher from falling into menial capacities. He received an excellent learned education, however, through the patronage of the Duke of Wirtemberg, took his degree of master of arts in 1591, and shortly afterwards obtained an astronomical post, which, as he tells us himself, he most unwillingly accepted. This was the chair of astronomy at Gratz, and, strange to say, Kepler felt alarmed that his own ignorance in that branch of science would only bring disgrace upon him. His voluminous correspondence, his works, his prefaces and dedications being all full of himself, we have thus the most minute de- NAPIER OF MERCHISTON. 389 tails of the progress of his fortunes and his mind. He was not long of dis- covering that he had entered the path of his fame, and two years after his appointment, produced that cosmographical work which even Tycho con- demned as a system of nature singularly imaginative. There was this dis- tinction betwixt the minds of Napier and Kepler, that, although the former has left some indications of being tinged with the superstition which then attached itself to the loftiest geniuses, he seems to have cast it aside in all his serious operations, and did not suffer his mind to be drawn aside from its progress to the Logarithms even by the allurements of magic squares, and the mystical number seven. * But with Kepler’s greatest works, his wildest extravagances are lavishly mingled, and we have to seek for the evidences of his immortality, amid his own records of the most extraordinary ideas that ever entered the human imagination. The first discovery which he announced with much complacency to the world was, that in the geometrical solids, namely, the sphere, the dodecahedron, the tetrahedron, the cube, the isosahedron, and the octohedron, he had detected the true reason of the number and arrange- ment of the planetary system. Such were the almost insane speculations which brought out Kepler’s wonderful powers of calculation. ‘‘ There were,” he says, “ three things in particular of which I pertinaciously sought the causes why they are not other than they are,—the number, the size, and the motion of the orbits. I attempted the thing at first with numbers, and con- sidered whether one of the orbits might be double, triple, quadruple, or any other multiple of the others; and how much, according to Copernicus, each differed from the rest. I spent a great deal of time in that labour, as if it were mere sport, but could find no equality either in the proportions or the differences, and I gained nothing by this beyond imprinting deeply in my me- mory the distances as assigned by Copernicus.” After succeeding, as he ima- gined, with his geometrical methods, he declares, that “ the intense pleasure I have received from this discovery never can be told in words; I regretted no more the time wasted; I tired of no labour; I shunned no toil of reckon- ing; days and nights I spent in calculations, until I could see whether this opinion would agree with the orbits of Copernicus, or whether my joy was to * One of the propositions in Robert Pont’s work on the “ Last Decaying Age of the World” is, « That there is a merveilous sympathie of periods of times in reckoning by sevens, and by Sab- patical years, and of the manifold mysteries of the number of seven.” 390 THE LIFE OF vanish into air.”* By the time, however, the canon of Logarithms made its, appearance, Kepler’s mind had atoned for his imagination. ‘Through the most chilling pecuniary difficulties, and the most distracting domestic broils, he struggled onwards to the discovery of those great laws of the planetary orbits, which have obtained for him the daring title of “ Legis- lator of the Heavens.” When Tycho was banished from Uranibourg, the moment he found a resting-place for himself and his instruments, he and Longomontanus returned to their observations of the heavenly bodies with the true spirit of philosophers, and with the same ardour as if no- thing had happened. Kepler joined them in the year 1600; and in the following was presented by Tycho to his new patron, the Emperor Ro- dolph, who made it his request that Kepler should assist the great astro- nomer, and at the same time bestowed upon him the title of Imperial Mathe- matician. Hence arose Kepler’s connection with the Rudolphine Tables, the great source of his future labours, and of which we shall afterwards hear something from himself in connection with Napier and Logarithms. Before Kepler knew of that invention, he had passed through most of the calcula- tions of those great astronomical discoveries which have been called Kepler’s Laws; and it was immediately after he had published the Harmonices Mundi, that we shall find he sat down to address a letter of thanks to Napier for the boon he had presented to the world. And well might Kepler do so notwithstand- ing all his success. Tycho had left him, among other bequests, the Herculean task of completing his Astronomical or Rudolphine Tables, for which the world of science looked so eagerly and so long. ‘They were the first that were founded on the system of Logarithms; and there was now little chance of the German’s finding himself in a dilemma, which once occurred to him. While examining the orbits of the planets, he had adopted a theory, whose results, after great labour, proved unsatisfactory ; he commenced the calculations upon a new theory, “ but was much astonished at finding the same exactly as on his former 7 hypothesis ; the fact was, as he himself discovered, although not until after several years, that he had become confused in his calculation, and when half * There is an excellent life of Kepler by Mr Drinkwater, who has translated into it copious extracts from Kepler’s works and correspondence. He has made great use of the Kepleri Epis- tole by Hansch. NAPIER OF MERCHISTON. 391 through the process, had retraced his steps, so as of course to arrive again at the numbers from which he started.” * We must not omit, that, like Napier, Kepler mingled with his scientific labours the study of recondite theology, and also of judicial astrology. His theological studies were not indeed pur- sued with the devotion and ability of our own philosopher ; but he surpassed him in astrology. He pretended, indeed, to a peculiar and purified creed on the subject. “ I maintain,” says he, “ that the colours and aspects, and con- junctions of the planets, are impressed on the natures or faculties of sublu- nary things, and when they occur, that these are excited as well in forming as in moving the body over whose motion they preside ;” after scorning the quacks in astrology, he adds, “ A most unfailing experience of the excite- ment of sublunary natures, by the conjunctions and aspects of the planets, has instructed and compelled my unwilling belief.” Such, generally, was the position in science of the most illustrious and laborious calculator in Europe at the time the Logarithms appeared; and, in reference to Dr Hutton’s history, it is material to attend to the first expressions used by Kepler on the subject. He was now in correspond- ence with every man of science on the Continent; and, in a letter dated 11th March 1618 to his friend Schikhart, after descanting upon the various difficulties and resources of trigonometry, he exclaims, “ A Scottish baron has started up, his name I cannot remember, but he has put forth some wonderful mode by which all necessity of multiplications and divisions are commuted to mere additions and subtractions, nor does he make any use of a table of sines ; still, however, he requires a canon of tangents, and the variety, frequency, and difficulty of additions and subtractions, in some cases exceed the labour of multiplication and division.” + ‘This was the first crude notion formed by Kep- * Drinkwater. + “ Extitit Scotus Baro, cujus nomen mihi excidit, qui preclari quid preestitit, necessitate omni multiplicationum et divisionum in meras additiones et subtractiones commutata, nec sinibus uti- tur: at tamen opus est ipsi tangentium canone: et varietas, crebritas, difficultasque additionum subtractionumque alicubi laborem multiplicandi et dividendi superat.” Myr Drinkwater, in his Life of Kepler, observes, “ the meaning of this passage is not very clear ; Kepler evidently had seen and used Logarithms at the time of writing this letter, yet there is nothing in the method to jus- tify this expression, “at tamen opus est pst tangentiwm canone.” The letter from Kepler to Napier, of which Mr Drinkwater was not aware, and which we shall afterwards quote, may throw some light upon this expression ; it certainly proves that Kepler did not peruse Napier’s work until the following year, when he instantly caught fire. 392 THE LIFE OF ler of a work which he had not as yet examined, but with which all his future labours and fame were to be identified. It would appear from these expressions, that he had not yet heard of that letter to Tycho in the year 1594, which he mentions in a subsequent correspondence with Cugerus; they also afford addi- tional evidence, that the idea of Longomontanus having suggested the inven- tion to Napier in the manner recorded by Wood, can have no foundation, as Longomontanus and Kepler had been fellow-calculators for years, living in the same house together, and if any thing even analogous had been previously imagined by either of them, it must have been instantly recognized. But where were all the “ learned calculators of the 16th and 17th centuries,” whom Dr Hutton pictures as evolving the Logarithms by profound reasonings upon the doctrine of progressions? And who were they ? Not Kepler, who, when he first heard of Napier’s method, could hardly form an accurate idea of its meaning. Not Tycho, nor Longomontanus, nor Galileo, nor any one of Kepler’s numerous correspondents, including, we should think, nearly all the learned calculators of the period. At length, however, Kepler, who to his dy- ing day never ceased to marvel at the achievement, seems a little excited by discovering that ove other person had actually approached the theory without being aware of it. In his Rudolphine Tables, published in the year 1627, he remarks, “ the accents in calculation Jed Justus Byrgius ou the way to these very Logarithms many years before Napier’s system appeared ; but being an indolent man, and very uncommunicative, instead of rearing up his child for the public benefit, he deserted it in the birth.” * This was the result of Kepler’s indefatigable inquiries, for nine years, as to who had ever thought of the Sys- tem before, and, giving him the fullest credit for the fact, it amounts to this, that Byrgius had made some observations upon the adaptation of an arith- metical to a geometrical progression, very naturally occurring to him in tri- gonometrical calculations. The Apices Logistict, to which Kepler alludes, are those accents which the Greeks used in order to change the value or mark the order of a symbol, as we use the cypher; and this is particularly exemplified in their sexagesimal division of the circle still in use, where the accents ’,",’, ’, &e. of minutes, seconds, thirds, fourths, &c. are an arithmetical progression denoting the fractional orders, the values of which descend in a ratio of 60, and * « Apices Logistici, Justo Byrgio, multis annis ante editionem Nepeiranam, viam preiverunt ad hos ipsissimos logarithmos, etsi homo cunctator, et scretorum suorum custos, foetum in partu destituit, non ad usos publicos educavit.” NAPIER OF MERCHISTON. 393 form the corresponding geometrical progression. It is obvious, however, that Kepler meant nohonour to his friend to the prejudiceof Napier. On thecontrary, the spirit in which he notices the fact, is, that Byrgius had substantially failed to perceive that a chapter of algebra might be composed in which that property of progressions would be reared into vast importance ; an importance never felt until Napier demonstrated it by a method far more nearly allied to the profound algebraic views of Newton, than those easy progressions,—so obvious in the Arabic scale itself, and through which, perhaps, Byrgius had been un- wittingly on a tract to Logarithms,—are to Napier’s system. The mathematician whose claim we are considering ranked not meanly in science ; he was instrument-maker and astronomer to the Landgrave of Hesse, and must have been well known to Kepler; he may have been “ homo cunc- tator,” but he was not so foolish as to have cast aside his own immortality had he really extended the Archimedean principle in any remarkable manner; he was a public astronomer, under high patronage, in a country teeming with ri- vals in science, and where a great mathematical discovery was the means of obtaining rank, wealth, and adoration; it is absolutely impossible, therefore, that an astronomer of the Landgrave of Hesse could have calculated tables of Logarithms, knowing what he was about, and then have cast them aside ; there was the gulf of ignorance betwixt him and Logarithms, and so we must construe the expressions of Kepler, “ faetum in partu destituit, non ad usos publicos educavit.” Supposing him even to have observed all the cu- rious properties of a corresponding series, under the fertile and flexible Arabic notation,—the parent of progressions,—he would not have been singular in thus obtaining a glimpse of Logarithms without knowing them ;* and there * Michael Stifels has a far stronger claim to be named in a history of Logarithms than Justus Byrgius. Montucla records him as an observer of progressions, but will not allow him any share whatever of the honour of Logarithms. He was a Protestant clergyman, born at Eslingen in Saxony, in 1509, who published at Nuremberg, so early as 1544, a very original and philosophi- cal work upon arithmetic and algebra, entitled Arithmetica Integra. In this he examines loga- rithmic properties of corresponding series of numbers, so ingeniously and profoundly that he al- most deserves to have made the great discovery. But his mind had not the grasp of Napier’s, and fell short even of the conception of bending the whole system of Numbers to these Archime- dean principles ; consequently, after labouring earnestly at progressions, anc talking con amore of their properties, his genius dies away into the doctrine of magic squares. So far from interfering with the fame of Napier, he affords the best illustration of the fact that no hints could suggest the Logarithms accidentally even to mathematical minds. Napier is the solitary being who said to 3D 394 | THE LIFE OF would still be this distinction betwixt Byrgius and Napier, that the former, neither seeking nor dreaming of such a power, stumbled upon a natural tract in the system of notation, which might have led him, but did not, to an im- perfect and accidental developement of Logarithms ; whereas the latter saw that the power was wanted, that calculation was impeded, and, to use his own words, “ began therefore to consider in my mind by what certain and. ready art I might remove those hindrances,” and in doing so sought no easy path pointed out to him by the progressive power of cyphers, but, plunging at once into the algebraic depth of his own original fluxionary system, took the very path which NEWTON and LEIBNITZ would have taken, and returned leading the whole system of Numbers captive to the properties of progressions. The distinguished Playfair, in stating to the full extent ' those properties as observed before Napier’s time, has well expressed the pro- per appreciation of such prior claims: “ Thus far, however,” he says, “ there was no difficulty, and the discovery might certainly have been made by men much inferior either to Napier or Archimedes. What remained to be done, what Archimedes did not attempt, and what Napier completely performed, involved two great difficulties. It is plain that the resource of the geometri- cal progression was sufficient when the given numbers were terms of that progression ; but if they were not it did not seem that any advantage could be derived from it. Napier, however, perceived, and it was by no means obvious, that all numbers whatsoever might be inserted in the progression, and have their places assigned in it. After concewing the possibility of this, the next difficulty was to discover the principle, and to execute the arithmetical pro- cess by which these places were to be ascertained. It isin these two points that the peculiar merit of his invention consists.” * When this idea occurred to Napier, then, and not till then, were Logarithms conceived ; when he set him- self to show how such intercalations could be generated, then, and not till himself I wILL DISCOVER SUCH A POWER, who sat down to the task, and who accomplished it. Sir John Leslie, when speaking of Stifels in his Dissertation, uses a careless expression. “ Stifels anticipated some of the later discoveries, pointed out the nature of Logarithms,” &c. Napier invented the very term; and that Leslie could mean no more than what we have already conceded to Stifels, is obvious from his saying elsewhere, that “ Napier’s life, devoted to the im- provement of the science of calculation, was crowned by the invention of Logarithms, the noblest conquest ever achieved by man.” * Dissertation. NAPIER OF MERCHISTON. 395 then, were Logarithms demonstrated ; and when he completed the laborious operation of calculating tables constructed upon those principles, then, and not till then, the world was in possession of Logarithms. Justus Byrgius is the solitary mathematician for whom any thing like an independent claim to the invention has been set up betwixt the time of Archi- medes and Napier. Not that it has ever been said that our philosopher bor- rowed any thing from the German ; for the priority of Napier’s publication, and the surpassing beauty of his algebraic method, has never met with contradic- tion. But there is a story that Kepler’s friend had actually computed tables of Logarithms years before Napier published his canon, and, consequently, that the German stands nearly in the same relation to this great discovery that Newton himself does to the infinitesmal calculus, in the celebrated competition with Leibnitz. It would, indeed, be singular, if this public astronomer had computed such tables without giving them to the world, or ever himself pretending to the discovery. Yet the facts have been imposingly detailed by Montucla in his great history of Mathematics, and hitherto without any refutation. If Dr Hutton, instead of confusing the history of Logarithms to the further detriment of Napier’s intellectual rights, by appearing to as- sume that the conquest, which our philosopher a/one imagined and accom- plished, was the work of many, had refuted the false claim we are about to expose, he would thereby have only done justice to his country. “ There is a geometer,” says Montucla, “ to whom we must here give a place, and that is, Juste Byrge. That which chiefly renders him worthy of notice is the fact, that he invented and constructed tables of Logarithms si- multaneously with Napier. Kepler represents him to us as a man of consi- derable genius, but thinking so modestly of his own inventions, and so indif- ferent about them, as to suffer them to be buried in the dust of his study ; and, says Kepler, for that reason he never gave any thing to the public through the medium of the press.* But Kepler was in error when he said so, and we shall proceed to unfold a tale not a little curious upon that sub- * This is a very erroneous version of the passage we have already quoted from Kepler’s Ta- bule Rudolphine, and argues literary carelessness on the part of Montucla, as may be detected in more than one instance in his great work. It will be perceived that Kepler confines his remark entirely to the extent which Byrgius had evinced his knowledge of Logarithmic properties, and says something totally different from Montucla’s paraphrase.—See supra, p. 392. 396 THE LIFE OF ject.* Notwithstanding what Kepler says of J. Byrge, Benjamin Bramer bears witness to the fact, that he (Byrge) did publish something relative to Logarithms. That author in a German work of his, entitled, Description of an Instrument very useful for perspective and drawing plans, (Cassel, 1630, 4to,) says expressly, “ It was upon these principles that my dear brother-in-law and master, Juste Byrge, constructed, more than twenty years ago, a beautiful table of progressions, with their differences from 10 to 10, calculated to 9 places, and which he caused to be printed at Prague in 1620, so that the in- vention of Logarithms is not Neper’s, but was made by Juste Byrge long before him.” Upon this unblushing assumption, Montucla continues his remarks. ‘“ But the work of this geometer was nowhere to be found, and probably would never have been discovered had not the passage led M. Kastner to recognize these tables among some old mathematical works which he had purchased. They bore this title in German: Tables of Arithmetical and Geometrical Progressions, with an introduction explanatory of their meaning and use in all manner of Calculations, by J. B. printed in the ancient city of Prague, 1620. The tables contain seven leaves and a-half, printed in folio, but the introduction announced is awanting, which leads to the conjecture, that some peculiar circumstances had stopped the progress of the work; and, indeed, Bramer informs us in another of his own works, that Juste Byrge contem- plated the publication of several of his inventions, and, for that purpose, had his portrait engraved in the year 1619, but the thirty years’ war, which un- happily desolated Germany, opposed an obstacle to his design.” Montucla then proceeds to give a specimen of the fragment of Byrgius taken from M. Kastner, and concludes his curious story, by deigning to extend his illustrious protection thus far over old John of Merchiston. ‘“ We must remark at the same time, that it would be unjust to conclude, from the work printed in 1620, that Byrge had invented Logarithms before Neper ; for the work of Neper appeared in 1614, and it is the priority of dates of works which determines at the bar of public opinion the anteriority of the invention. How then does Bramer from that date, 1620, arrive at the conclusion, that his brother-in-law had made the discovery long before Napier ? It is well known, that the date * « Mais Kepler étoit dans l’erreur en cela, et nous allons développer ici une anecdote assez curieuse sur ce sujet.” NAPIER OF MERCHISTON. 397 of an invention requiring much calculation is necessarily anterior to that of publication, and Neper is equally entitled to the assumption, that his inven- tion existed in his head for several years before he published it ; and besides, in a court of law itself, Byrge would lose his suit, for, according to the strictest administration of justice, a date of publication anterior by six years must be held to have afforded an opportunity of becoming acquainted with the discovery, and disguising it under another form. Let us be contented, therefore, with associating at a distance, and to a certain extent only, Byrge with the honour of that ingenious invention ; but the glory must always be- long to Neper.” * Fair and softly, M. Montucla, “ de l’Institut National de France, An vii.” Britain has but one name by which she can claim her place in that page of the history of physical astronomy, where Tycho, Kepler, Galileo, are record- ed, and it is Napier,—Scotland has in him her solitary philosopher majorum geniium, and must not part with a ray of his glory. The value of Byrgius’s share of any honour in the matter may be expressed by that ghostly symbol which is the soul of Arabic notation, 0. We might say so upon the evidence adduced in his favour, which is totally inadequate to sustain his claim. His brother-in-law is, under the circumstances, not competent evidence; for the peremptory manner in which he springs from so vague a statement to the astounding conclusion, that Byrgius, and not Napier, is the Inventor of Logarithms, proves Bramer to have been either an idiot or a false witness. The miserable fragment of miscalculated tables discovered by Kastner proves nothing, for there is neither description nor claim attached to them, and their date is 1620; and any support which the claim attempted to be reared upon that fragment may seem to obtain from the notice of Kepler (also very vague) is more than neutralized by Kepler himself. But there exists positive evi- dence against the claim, shadowy as that is, “ et nous allons développer ici une anecdote assez curieuse sur ce sujet.” According to Bramer, his kinsman had calculated tables of Logarithms more than twenty years before 1630. As he has not fixed the date, we take the assumption as referring to the year 1609. “ But,” says Kepler, writing in the year 1624, and without the slightest notice of Byrgius, “ a certain Scotchman, so early as the year 1594, wrote to Tycho a promise of that won- derful canon.” According to Bramer, his kinsman, the “ homo cunctator,” * Histoire des Mathematiques, Tom. ii. p. 9, et infra. 398 THE LIFE OF did so far bestir himself as to have his portrait engraved, in the year 1619, for a frontispiece to his great discoveries, among which, and probably the least, were the Logarithms! In 1620 the fragment of his tables was printed at Prague, but without frontispiece or anything else. Now it happens, though Montucla was not aware of the fact, that the very place where Kepler himself first saw a copy of John Napier’s Canon Mirificus was THE ANCIENT CITY OF PRAGUE, and this was in the year 1617. Our autho- rity is the letter from Kepler to Napier, with which these Memoirs con- clude, and which Montucla had never seen. So the “ homo cunctator” calcu- lated tables of Logarithms in 1609, and then cast them among the rub- bish of his study; in the year 1617 a copy of Napier’s Canon is laid, as the wonder of the day, before Kepler himself, the oracle of European science, in the city of Prague; from that moment Kepler’s whole existence is identified with his love of Logarithms, and all that he ever says for his friend Byrgius is, that he did not make the discovery; in 1619 (two years after Napier’s death,) the “ homo cunctator” has his portrait engraved; in 1620 he is said to have printed at Prague some isolated and useless fragment of a table, but it is not even pretended that he put forth any claim; ten years afterwards, namely, in 1630, Bramer, brother-in-law to the “ homo cunctator,” has the effrontery to announce, and without so much as a detailed or explicit account in support of his allegation, that Justus Byrgius, and not John Napier, is the inventor of Logarithms. We regret to add to the name of Montucla, that of another distinguished historian of science, as having been carried by this ground- less pretension, which was probably a villanous though weak attempt to wrest the laurels from the grave of a foreigner.* M. Kluegel, in his philosophical dictionary, a work of great ability, records, that “ Neper in Scotland, and Jobst Byrg in Germany, were the first who, without any intercommunica- tion, calculated tables of Logarithms.” + It is some consolation to find, that * Any one who will take the trouble to examine the table of Byrgius, as given by Montucla in his French work, and Kluegel in his German one, will at once perceive how wretched an affair it is; and how easily it may have been an abortive attempt to examine Napier’s system, whose secret method of construction was not published until the year 1619, and might not reach Prague for some time afterwards. Kepler himself, as we shall find, wrote in that very year to Napier, entreating, in his own illustrious name, and that of all the scientific men around him, that he ~ would give the world his secret. Where was the “homo cunctator” then ? Viewed in every igh the claim for Byrgius is either nonsense or roguery. + “ Neper in Schottland und Jobst Byrg in Deutschland sind die ersten welche, ohne etwas von einander zu wissen, Logarithmische Tafeln berechnet haben.” NAPIER OF MERCHISTON. 399 our philosopher is admitted to an equal share, and has no other competitor. But how happened it, we would ask M. Kluegel, that Kepler gave all the glory to Napier, and none to his own countryman ? This same author expresses most graphically the enthusiastic zeal with which the legislator of the stars rushed upon the Logarithms; “ Kepler ergriff Nepers Erfindung mit Eifer,” —Kepler seized Napier’s discovery with enthusiasm,—now Kepler expressly regards the speculation of Byrgius with contempt. Montucla and Kluegel have, in every other respect, done justice to the illustrious Scotchman. Dr Hutton, actuated it would seem by some feel- ing of national jealousy, has treated Napier’s fame and memory in the most unbecoming manner. Anxious to imbue his students with an idea that those profound and philosophical views which engendered the Logarithms were diffused over all ages, and, towards the consummation, equally shared among many calculators, this author, in the progress of casting every doubt he can upon Napier’s intellectual rights, thus winds up his own peculiar exa- mination of the birth of that wonderful invention. “ This, however, was no newly discovered property of numbers, but what was always well known to all mathematicians, being treated of in the writings of Euclid, as also by Archimedes, who made great use of it in his Avenarius, a treatise on the number of the sands, namely, in assigning the rank or place of those terms of a geometrical series produced from the multiplication together of any of the foregoing terms by the addition of the corresponding terms of the arithmeti- cal: ‘series which served as the indices or exponents of the former. And the reason why tables of these numbers were not sooner composed was, that the accuracy and trouble of trigonometrical computation had not sooner rendered them necessary. It is therefore not to be doubted, that, about the close of the sixteenth and beginning of the seventeenth century, many persons had thoughts of such a table of numbers besides the few who are said to have attempted it.”* The reason why tables of Logarithms were not sooner compos- ed was, that they were of no use before the year 1614, is here solemnly recorded by one who calls himself their historian! The same might, with equal sense and justice, be said of the invention of printing, or of the steam-engine, or of any other mighty impulse which the human mind ever received. It is curious that a mathematical professor (we do not call him a philosopher) * ‘History of Logarithms, by Charles Hutton, LL. D., F.R.S., and Professor of Mathematics in the Royal Military Academy, Woolwich. 400 THE LIFE OF should cause the question.—Would Logarithms have been of no value in the schools of Alexandria? Would Euclid, and Archimedes, and Apollonius, and Hipparchus, and Ptolemy, and Diophantus, not all have seized, like Kepler, the Logarithms mt Kifer? A perfect notation in Arithmetic, and the infant Algebra itself came even to the dark ages. Were those gifts too soon for Science ? In the dusky land of the birth of algebra, had the Logarithms lurked far away at the mysterious fountain of numbers, would no wandering prophet of science, no glorious dealer in immortal merchandize, no Leonardo, or Gerbert, or de Burgo, have brought home that treasure, too, in his bosom rejoicing ? When the reviving torch of science first flashed in the hands of Purbach and Regio- montanus, would they have rejected the key of calculation? Had it appeared a century before Napier, would not physical astronomy have been as far ad- vanced in his time as it was a century after, and would not NAPIER have been NEWTON ? But there were many persons having thoughts of such a table of numbers be- sides the few who are said to have attempted it! Dr Hutton, in support of this assertion, first tells us, that “ some say Longomontanus invented Logarithms ;” but he dare not give him credit for much more than the zdea of them, being forced to admit, that Longomontanus lived thirty-three years after the publica- tion of the invention, and never hinted aclaim. He quotes, however, the story from the Athene Oxonienses, as if it were to be taken literally; tells us that it is rested upon the authority of Oughtred and Wingate; but without adding that it is not confirmed by the writings of those philosophers. He then clings to Byrgius; “ Kepler also says, that one Juste Byrge, assistant astronomer to the Landgrave of Hesse, invented or projected Logarithms long before Neper did, but that they had never come abroad on account of the great reservedness of their author with regard to his own compositions.” * But Hutton, though he suppresses what so materially qualifies the words of Kepler, and ventures not into the slightest examination of the pretension for Byrgius (who never made it for himself) is fond of the story, and does what he can to fix it upon the legislator of the stars as an unqualified assertion of his; for, speak- ing of the Rudolphine Tables, our author takes occasion to repeat, “ and here it is that he (Kepler) mentions Justus Byrgius as having had Lo- * Is that a fair or true statement of Kepler’s expressions fetum in partu destituit, non ad usos publicos educavit ? Those expressions amount not to a statement that Byrgius never published tables, but that he never found the Logarithms. NAPIER OF MERCHISTON. 401 garithms before Napier published them.” These, Longomontanus and Byr- gius, are all whom Dr Hutton can find to represent his learned calculators of the sixteenth and seventeenth centuries, who anticipated or coincided with Napier in the discovery. We have already given a few hurried sketches of the great actors in the scientific world, from the revival of letters to the pub- lication of Logarithms, which, though necessarily very imperfect, will be sufficient to meet this unjust appreciation by a modern English author. But he is contradicted by the history of science, ancient and modern, and by every philosopher of greatest name, both in Napier’s time and ours. Among the finest characteristics of our philosopher’s invention was the un- hoped-for manner in which it removed a pressure, long and severely felt, and which might have crushed the temple of science, had that not possessed such a pillar as Kepler. ‘To use the expressions of a distinguished writer, “ What all mathematicians were now wishing for, the genius of Neper enabled him to discover ; and the invention of Logarithms introduced into the calculations of trigonometry a degree of simplicity and ease, which no man had been so sanguine as to expect.” * Kepler, Ursine, Speidell, Gunter, Briggs, Vlacq, Cugerus, Cavalieri, Wolff, Wallis, Halley, Keill, and a host of others, all bear witness against Dr Hutton, in the honourable and enthusiastic manner they acknowledge Napier as the only author of that revolution in science. It seems, however, that this writer was only paving the way for a more de- termined attack upon the memory of our philosopher. He notices the Eng- lish translation of the Canon as having passed through Napier’s hands, and also, that there was “ a preface by Henry Briggs, of whom we shall presently have occasion to speak more at large, on account of the great share he bore in perfecting the Logarithms ;” then he adds, “ the note which Baron Napier inserted in this English edition, and which was not in the original, was as follows :—But because the addition and subtraction of these former numbers may seem somewhat painful, I intend (if it shall please God) in a second edition, to set out such Logarithms as shall make those numbers above written to fall upon decimal numbers, such as, 100000000, 200000000, 300000000, &c. which are easy to be added or abated to or from any other number.—This note (continues Dr Hutton) had reference to the alteration of the scale of Logarithms in such manner, that 1 should become the Logarithm of the ratio of 10 to 1, instead of the number 2.3025851, which Napier * Review of Woodhouse’s Trigonometry —Edin. Review, Vol. xvii. p. 124. 1810. 3 E 402 THE.LIFE OF had made that Logarithm in his table, and which alteration had before been recommended to him by Briggs, as we shall see presently. Napier also in- serted a similar remark in his Rabdologia, which he printed at Edinburgh in 1617.” After examining various modifications and editions of the tables, our author then proceeds to accuse John Napier of breach of truth, breach of honesty, and breach of friendship. He quotes some extracts from the corre- spondence of Briggs with Archbishop Usher, and the account which the former himself has given of his first visit to Merchiston, all of which are directly con- tradictory of what he means to found ; and these, his own evidence, we shall present against that author in a less garbled form, after abstracting his asser- tions and accusations. ‘“ Mr Henry Briggs, (he says,) not less esteemed for his great probity and other eminent virtues, than for his excellent skill in the mathematics,” &c. “ appears to be the first person who formed the idea of this change in the scale, which he presently and generously communicated, both to the public in his lectures, and to Lord Napier himself, who afterwards said, that he also had thought of the same thing.” He then quotes the positive de- claration of Briggs, that the Logarithms were improved according to Napier’s own conception and advice; and yet proceeds: “ So it is plain that Briggs was the inventor of the present scale of Logarithms, in which one is the Logarithm of the ratio of 10 to 1, and 2 that of 100 to1, &c. and that the share which Napier had in them was only advising Briggs to begin at the lowest number, 1,” &c. He goes on to depreciate Napier’s important modification of the improved plan, notices a preface of Briggs written after our philosopher's death, and quotes this passage from it, ““ Why these Logarithms differ from those set forth by their most illustrious inventor of ever respectful memory, in his Canon Mirificus, Ir Is TO BE HOPED his posthumous work will shortly make appear.” Having laid his foundation by these capital letters, Dr Hutton thus winds up his calumny against the inventor of Logarithms. “ As Napier, after communication had with Briggs on the subject of altering the scale of Lo- garithms, had given notice, both in Wright’s translation, and in his own Rabdologia, printed in 1617, of his intention to alter the scale, ( though it appears very plainly that he never intended to compute any more,) with- out making any mention of the share which Briggs had in the alteration, this gentleman modestly gave the above hint. But not finding any regard paid to it in the said posthumous work, published by Lord Napier’s son in 1619, NAPIER OF MERCHISTON. 403 where the alteration is again adverted to, but still without any mention of Briggs, this gentleman thought he could not do less than state the grounds of that alteration himself, as they are above extracted from his work published in 1624. Thus, upon the whole matter, it seems evident that Mr Briggs, whether he had thought of this improvement in the construction of Logarithms, of making 1 the Logarithm of the ratio of 10 to 1, before Lord Napier or not (which is a secret that could be known only to Napier himself,) was the first person who communicated the idea of such an improvement to the world; and that he did this in his lectures to his auditors at Gresham College in the year 1615, very soon after his perusal of Napier’s Canon Mirificus Logarithmorum in the year 1614. He also mentioned it to Napier, both by letter in the same year, and on his first visit to him in Scotland in the summer of the year 1616, when Napier approved the idea, and said it had already occurred to himself, and that he had determined to adopt it. It would therefore have been more candid in Lord Napier to have told the world in his second edition of his book, * that Mr Briggs had mentioned this improvement to him, and that he had thereby been confirmed in the resolution he had already taken be- fore Mr Briggs’s communication with him, to adopt it in that his second edition, as better fitted to the decimal notation of arithmetic which was in general use. Such a declaration would have been but a piece of justice to Mr Briggs; and the not having made it cannot but incline us to suspect, that Lord Napier was desirous that the world should ascribe to him alone the merit of this very use- ful improvement of the Logarithms, as well as that of having originally in- vented them ; though, if the having first communicated an invention to the world be sufficient to entitle a man to the honour of having first invented it, Mr Briggs had the better title to be called the first inventor of this happy im- provement of Logarithms.” With the partiality which characterizes the whole of his incoherent attack, Dr Hutton studies to keep out of view that the improvement in question is not of the nature of an invention at all, but, at best, is a mere derivative idea, readily suggested by the invention of another. “ Various systems of Logarithms,” says Professor Playfair in his Dissertation, “ ¢¢ 7s evedent, may be constructed according to the geometrical progression assumed ; and of these, * Napier never published a second edition of his book; and his son, who gave the world the Constructio after the philosopher's death, laments in the preface that his father died even before he had prepared that second edition for the press. 404 THE LIFE OF that which was first contrived by Napier, though the simplest and the foun- dation of the rest, was not so convenient for the purposes of calculation as one which soon afterwards occurred, both to himself and his friend Briggs, by whom the actual calculation was performed. The new system of Logarithms was an improvement practically considered ; but, in as far as it was connect- ed with the principles of the invention, it ¢s only of secondary consideration.” But Dr Hutton seems not to have been qualified to judge betwixt two of the highest minded philosophers in Europe. If Napier, when he expressly declar- ed that he had the improvement in a better shape long before his friend, and upon two separate occasions publicly announced his intention to publish it as his own, did all this in order to wrest the merit from his friend, we must not call him uncandid merely, but a rogue. If Briggs was conscious and proud of his own suggestion, and anxious that the world should know it, yet left it to his friend for years to make the acknowledgment, though he half sus- pected that friend’s intention to cheat him, and then, when he found he had cheated him, waited for five years longer before he told his story, and after all told it in Napier’s favour and not his own, we need not speak of the modesty of Briggs, for he must have been a fool. Such is the inevitable re- sult of Dr Hutton’s view, and it is a relief to turn to the truth. Henry Briggs was then the Kepler of England. He was ten years younger than Napier, and was distinguished in navigation and astronomy before the close of the sixteenth century. About the year 1596 he was ap- pointed professor of geometry in the munificent establishment founded by Sir Thomas Gresham, where he devoted himself particularly to astronomy, and became known to the most celebrated men of his day. He was the intimate friend and literary coadjutor of Edward Wright, and also the friend and cor- respondent of the great James Usher, Archbishop of Armagh. Kepler was the luminary to whom Henry Briggs chiefly looked, until Napier fascinated him. From that moment he continued to revolve round the genius of the Scottish philosopher, so long as his own career lasted; and Napier, in re- turn, called him “ my most beloved friend.” In Usher’s correspondence, there is a letter, dated August 1610, from Briggs to that prelate, an extract from which will best show the nature and inclination of Napier’s friend :— “ Concerning eclypses, you see by your own experience, that good purposes may in two years be honestly crossed, and, therefore, till you send me your tractate you promised the last year, do not look for much from me, for, if any NAPIER OF MERCHISTON. 405 other business may excuse, it will serve me too. Yet am I not idle in that kind, for Kepler hath troubled all, and erected a new frame for the motions of all the seven upon a new foundation, making scarce any use of any former hypotheses ; yet dare I not much blame him, save that he is tedious and ob- scure ; and at length coming to the point, he hath left out the principal verb. I mean his tables both of middle motion and prosthaphereseon, * reserving all, as it seemeth, to his Tab. Rudolpheas, setting down only a lame pattern in Mars; but I think I shall scarce with patience expect his next books, unless he speed himself quickly.” Little did Briggs then know what was in store for himself and Kepler, and the Rudolphine Tables. Before those long-ex- pected tables were published, the Logarithms appeared ; and Kepler, the mo- ment he knew it, unwove his web, and remodelled the work upon this new chapter in science. It must have been early in the year 1614 that the Canon Mirificus issued from the press, because Edward Wright died in 1615, and yet he had completed the translation, sent it to the author in Scotland, and received it back revised before his death. It was then published, as we have already observed, by Samuel Wright, but under the auspices of Briggs, who wrote a preface, wherein he informs us,— Gentle Reader, seeing I have public- ly taught the meaning and use of this book at Gresham-House, and have had some charge about this impression committed unto me, both by the honour- able author, the L. of Marchiston, and by my very good friend, Mr Edward Wright, the translator ; and seeing the one who hath most right, and is best able to commend it, is so far absent, and the other hath made a most happy change of this place and life for a better; thou mayst haply expect that I should write somewhat that may give some taste of the excellent use of it,” &c. The expressions used by Briggs in his first notice of the great discovery to Usher, in a letter, dated Gresham-House, 10th March 1615, are very in- teresting. After speaking of the Arabic versions of the Greek philosophers, * « There is a passage in the life of Tycho Brahe by Gassendi, which may mislead an inatten- tive reader to suppose, that Napier’s method had been explored by Herwart at Hoenburg, ’tis in Gassendi’s observations on a letter from Tycho to Herwart of that day of August 1599. . Dixit Hervartus nihil morari se solvendi cujusquem triangul difficultatem ; solere se enim multiplica- tionum ac divisionum vice additiones solum, subtractiones 93 usurpare (quod ut fiert posset, do- cuit postmodum suo Logarithmorum Canone Neperus.) But Herwart here alludes to his work afterwards published in the year 1610, which solves triangles by Prosthaphzresis,—a mode totally different from that of the Logarithms.”—Account of the Life, 3c. of Napier, by Lord Buchan and Dr Minto. 406 THE LIFE OF and also holding some discourse concerning eclipses, he adds, “‘ Napper, Lord of “Markinston, hath set my head and hands a work with his new and admirable Logarithms. I hope to see him this summer, if it please God, for I never saw book which pleased me better, or made me more wonder. I purpose to discourse with him concerning eclipses, for what is there which we may not hope for at his hands.”* Dr Thomas Smith, the biographer of Usher and Briggs, has painted in vivid colours the state of excitement into which the latter was thrown by the Canon Mirificus. He says, that Ursin, Kepler, Frobenius, Batschius, and others, received it with great honour, but none more so than Briggs. ‘“ He cherished it as the apple of his eye; it was ever in his bosom, or his hand, or prest to his heart, and, with greedy eyes and mind absorbed, he perused it again and again. In his study, or in his bed, his whole thoughts were bent upon illustrating it, and bringing it by new stores to the last stage of perfection ; and he considered that his thoughts could not be more fruitfully, or beautifully, or gloriously, bestowed than upon this most illustrious discipline; for he regarded all other works as idleness. It was the theme of his praise in familiar conversation with his friends, and, ex cathedra, he expounded it to his disciples.” + Napier was prepared for the visit of this enthusiastic disciple some time before Briggs arrived in Scotland, by the presence of one John Marr, a mathematician attached to the household of King James. The philosopher’s eldest son was still with his majesty, and by this time had risen to be a privy-councillor. Aware of his father’s retiring dispositions, probably he thought it necessary to send John Marr to prepare him to receive England’s most ardent and illustrious philosopher, who designed himself the “ lover of all them who love the mathematics.” | We may imagine how great the ardour must have been that could induce one so completely occupied as Henry Briggs, with the most laborious and varied science, to undertake a journey to Scotland, which in those days Englishmen considered a pilgrimage to the desert. The fact also affords a striking proof, that, whatever ideas might at this time have already occurred to Briggs as to practical improvements in the structure of the system of Lo- * Usher's Letters, p. 36. + “ Hunc in deliciis habuit, in sinu, in manibus, in pectore gestavit, oculisque avidissimis, et mente attentissima, iterum iterumque perlegit,” &c.— Vita Henrici Briggii, Scriptore Thoma Smith, p. 6. { Preface to Wright’s Translation, by Henry Briggs. 4 NAPIER OF MERCHISTON. 407 garithms, he considered those ideas merely derivative, and by no means of the nature of an independent invention. He had stated them to his class, as he informs us himself, in the year 1615, but thought so little of his discovery as an intellectual achievement, that he does not mention the matter in his correspondence to Usher, and took no step in it further than to put his ideas into such a shape as might be fit for inspection by Napier. Him he obviously considered the sole author of Logarithms, whatever shape or structure the sys- tem could be made to assume. It was in the summer of the year 1615, that the English philosopher, the pride of Oxford, and who is recorded in the registers of Alma Mater as “ vir doctrina clarus, stupor mathematicorum, moribus ac vita integerrimus,” left his studies in London to do homage to the Scotch philosopher. They who know no more of Logarithms than merely to call them “ an useful abbreviation of a par- ticular branch of the mathematics,” can only regard the ecstacy of Briggs, his ca- resses of the volume, his adoration of the author, his discussions by day and his study by night, his long journeyings, and his years of toil in that cause, as the conduct of one whom too much learning had rendered mad. A more enlight- ened view of the subject brings before us the vast results of the system, and we can then better appreciate and respect such enthusiasm. But if we look more closely to the state of the scientific calculus in Napier’s day, if we examine the structure of the Canon Mirificus itself, the philosophy of its demonstrations, and the whole developement of this unlooked-for aid, and then compare it with the disjointed and timid unfoldings of algebraic analysis, shared among many learned calculators long after Napier’s time, we are impressed with the belief, that, in order to produce such an institute, his mind must have been thickly sown with the germs even of the higher calculus, and we feel that his friend was right, as, struck at this first great move in the chaos of calculation, he exclaimed, “ for what is there which we may not hope for at his hands.”* * Dr Hutton, while quoting from that letter Briggs’s first notice of the Canon Mirificus, sup- presses this sentence. But it is material in the question how far Briggs himself credited Napier when the latter said he had anticipated him in the conception of the improvement. It is the au- thor’s object to prove that Briggs did not believe Napier, and that he endeavoured, after Napier’s death, in the weakest manner, to insinuate to the world that Napier had cheated him. But this is a calumny against Henry Briggs no less than against John Napier. Dr Hutton also says that Briggs’s first visit to Napier was in the summer of 1616, and thus the latter would have had a 408 THE LIFE OF Henry Briggs, journeying on that high mission, before even Kepler knew that science was emancipated, must have felt deeply —when looking forth He saw the empress of the north Sit on her hilly throne ; Her palace’s imperial bowers, Her castle proof to hostile powers, Her stately halls and holy towers,— and his heart would beat higher still when first there rose upon his sight the old gray tower of Merchiston. * But with whatever excited feelings he approached the place, they were responded to from the bosom of its illustrious owner. John Marr himself, who was an eye witness of that meeting, described it to William Lilly, King Charles's astrologer, with a graphic minuteness which assures us.of the truth of the picture; and Lilly in his life and times thus narrates it to Elias Ashmole. “ I will acquaint you with one memorable story related unto me by John Marr, an excellent mathematician and geometrician, whom I conceive you remember. He was servant to King James I. and Charles I. When twelvemonth to think of his friend’s suggestion by letter, without letting him know till they met that he had the improvement before Briggs communicated it. Now the fact is certain, that Briggs followed his letter to Napier as soon as he could in 1615. He says so in his letter to Usher of that year, and as Napier died in the spring of 1617, and Briggs visited him two succes- sive summers, the first visit must have been in 1615. * The reader has been presented with a delineation of Merchiston Tower from the pencil of Williams. What follows is from the pen of Sir Walter Scott. ‘ This fortalice is situated upon the ascent, and nearly about the summit of the eminence called the Borough-moor-head, within a mile and a-half of the city walls. In form it is‘a square tower of the fourteenth or fif- teenth century, with a projection on one side. The top is battlemented, and within the battle- ments, by a fashion more common in Scotland than in England, arises a small building with a steep roof, like a little stone cottage erected on the top of the tower. This sort of upper storey, rising above the battlements, being frequently of varied form, and adorned with notched gables and with turrets, renders a Scottish tower a much more interesting object than those common in Northumberland, which generally terminate in a flat battlemented roof, without any variety of outline. It is not from the petty incidents of a cruel civil war that Merchiston derives its re- nown ; but as having been the residence of genius and of science. The celebrated John Napier of Merchiston was born in this weather-beaten tower; and a small room in the summit is pointed out as the study in which he secluded himself while engaged in the mathematical researches which led to his great discovery. The battlements of Merchiston tower command an extensive view of great interest and beauty.”’—Provincial Antiquities of Scotland. NAPIER OF MERCHISTON. 409 Merchiston first published his Logarithms, Mr Briggs, then reader of the astro- nomy lectures at Gresham College, in London, was so surprised with admira- tion of them, that he could have no quietness in himself until he had seen that noble person whose only invention they were. He acquaints John Marr therewith, who went in Scotland before Mr Briggs, purposely to be there when these two so learned persons should meet. Mr Briggs appoints a certain day when to meet at Edinburgh, but, failing thereof, Merchiston was fearful he would not come. It happened one day as John Marr and the Lord Napier were speaking of Mr Briggs, ‘ Oh! John,’ saith Merchiston, ‘ Mr Briggs will not come now;’ at the very instant one knocks at the gate, John Marr hasted down, and it proved to be Mr Briggs to his great contentment. He brings Mr Briggs into my Lord’s chamber, where almost one quarter of an hour was spent, each beholding other with admiration, before one word was spoken. At last Mr Briggs began,—‘ My Lord, I have undertaken this long journey purposely to see your person, and to know by what engine of wit or ingenuity you came first. to think of this most excellent help unto astronomy, viz. the Lo- garithms; but, my Lord, being by you found out, I wonder nobody else found it out before, when, now being known, it appears so easy. * He was nobly entertained by the Lord Napier; and every summer after that, during the Laird’s being alive, this venerable man went purposely to Scotland to visit him.” We must now give Briggs’s own account of those visits, from which it might have been conceived impossible that envy itself could have extracted anything to disturb the beautiful picture of friendship and intellectual co-ope- ration betwixt these great men. Seven years after Napier’s death, Briggs tells us in his preface to the Arithmetica Logarithmica, published in Lon- don, 1624, “ That these Logarithms differ from those which that illus- trious man, the Baron of Merchiston, published in his Canon Mirificus, must not surprise you. For I myself, when expounding publicly in London their doctrine to my auditors in Gresham College, remarked that it would be much more convenient that 0 should stand for the Logarithm of the whole sine, as in the Canon Mirificus, but that the Logarithm of the tenth part of the same whole sine, that is to say, 5 degrees, 44 minutes, and 21 seconds should be 10,000,000,000. Concerning that matter, I wrote immediately to * This interferes with Dr Hutton’s fable of the learned calculators of the 16th and 17th cen- turies. 3 F 410 THE LIFE OF the author himself; and, as soon as the season of the year and the vacation time of my public duties of instruction permitted, I took journey to Edin- burgh, where, being most hospitably received by him, I lingered for a whole month. But as we held discourse concerning this change in the system of Logarithms, he said, that for along time he had been sensible of the same thing, and had been anxious to accomplish it, but that he had published those he had already prepared, until he could construct tables more convenient, if other weighty matters and his frail health would suffer him so todo. But he conceived that the change ought to be effected in this manner, that 0 should become the Logarithm of unity, and 10,000,000,000 that of the whole sine; which I could not but admit was by far the most convenient of all. So, rejecting those which I had already prepared, I commenced, under his encour- aging counsel, to ponder seriously about the calculation of these tables; and in the following summer I again took journey to Edinburgh, where J sub- mitted to him the principal part of those tables which are here published, and I was about to do the same even the third summer, had it pleased God to spare him to us so long.” * * « Quod Logarithmi isti diversi sunt ab iis quos clarissimus vir, Baro Merchistonii, in suo edidit Canone Mirifico non est quod mereris. Ego enim, cum meis auditoribus Londini, publicé in Collegio Greshamiensi horum doctrinam explicarem, animadverti multo futurum commodius si Logarithmus sintis totius servaretur 0 (ut in Canone Mirifico) Logarithmus autém partis deci- mz ejusdem sintis totius, nempe, sints 5 graduum, 44 minutorum, et 21 secundorum, esset 10,000,000,000.

I have translated the word dudum in this passage, ‘ for a long time,” because it appears to me that such is its general acceptation and its obvious meaning here. Dr Hutton of course translates “se idem dudum sensisse et cupivisse’ in the weakest sense, “ he said that he had formerly thought of it, and wished it.” Baron Maseres has also animadverted upon Napier for alleged injustice to Briggs. He professes to give an accurate reprint of the passage, but has omitted the word dudum. ——Scriptores Logarithmici, Vol. vi. pp. 707, 708. NAPIER OF MERCHISTON, 411 This acknowledgment on the part of Henry Briggs,—that he had no me- rit, save the zeal and the toil, in bringing Logarithms to perfection,—that the very improvement which struck himself while expounding the canon, and which he had publickly noticed to a London audience, (so that a false impression of his own merit in the matter might have gone abroad,) was in _ possession of the author himself long before, and in a far preferable form,— that he, Briggs, had therefore cast aside all he had laboured on his own con- ceptions, and bent his mind to the instructions of the venerable author,—that season after season, until death divided them, he travelled, like the comet to the sun, to draw light from his master, without whose advice and approba- tion he would not venture one step in his arduous undertaking,—says as much for the heart of Briggs as for the head of Napier. But Dr Charles Hutton, modelling a view of these facts upon his own mind, has insulted the memory of Henry Briggs, by interpreting that beauti- ful acknowledgment into a miserably weak defence of literary property alleged to have been pirated by Napier. The passage speaks for itself; but a view of the preliminary circumstances, some of which Dr Hutton has suppressed, while others he has wrested to his own purpose, will render it still more unequivocal. On the last page of the tables in the original edition of the Canon Mirifi- cus, but neither in the translation nor in any other edition, is the following very interesting sentence from Napier himself, which he titles “ Admonition.” “ Seeing that the calculation of this table, which ought to have been perfected by the labour and pains of many calculators, * has been finished by the ope- * It cannot be known to those not conversant with the theory and structure of Logarithms, how beautiful is the one, and how laborious the other. Some idea of the labour, however, which Napier had already undergone, and which Briggs was now even more laboriously repeating, may be derived from the words of an able mathematician while examining that change in the system to which our text refers. ‘ There are various artifices and methods for computing Logarithms. But the art of computing Logarithms, and dexterity in that art, would by themselves be of no use in expediting calculation : if, for instance, we had to multiply 31.523 by 17.81, and to divide the product by 5.4312, it would be a most long method of performing the operation to investigate the Logarithms of these numbers: but it is the circumstance of registering computed logarithms in tables, and, by the art of printing, of multiplying such tables, that enables us to compute quick, ly. The calculation of Logarithms is exceedingly operose ; but one man calculates for thousands, and the results of tedious operations are made subservient to the abridgement of similar ones,” Woopnovse, Treatise on Trigonometry, p. 167, 412 THE LIFE OF ration and industry of one alone, it is not surprising if many errors have crept into them. I beseech you, benevolent readers, pardon these, whether caused by the weariness of computation or an oversight of the press ; for, as for me, declining health, and weightier matters have prevented my adding the last finish. But if I shall understand that the use of this invention proves acceptable to the learned, I will, perhaps, shortly give (God willing) the philosophy, and method either of amending this Canon, or of construct- ing a new one upon a better plan; so that through the diligence of many calculators, a Canon more highly finished and accurate than the work of a single individual could effect, may at length see the light. NOTHING Is PER- FECT AT ITS BIRTH.” * It cannot be doubted, when we couple this sentence with Napier’s subsequent declaration of having fora long time conceived a better system of Logarithms, that hehere alludes to the very improvement after- wards adopted ; now the sentence is printed in the first edition from which Briggs expounded the Logarithms at Gresham College when the idea struck himself, and Dr Hutton takes no notice of it whatever. In the English translation, which appeared in 1616, the sentence quoted above is omitted. Had Napier been capable of cheating his friend, that sen- tence, which appears at least to refer to the improvement, would have been re- tained. The reason it was omitted is obvious: the revised translation was sub- sequent to the meeting of Briggs with Napier : the acuteness of the former, though it had not led him to the precise mode of Napier’s improvement, had very nearly done so: this necessarily brought the matter to a point, and accord- ingly, instead of the “ Admonitio” in the Latin copy, Napier inserted that new sentence in thetranslation which states explicitly the improvement in the terms * ApMONITIO. Quum hujus tabulz calculus, qui plurimorum Logistarum ope et diligentia perfici debuisset, unius tantum opera et industria absolutus sit, non mirum est si plurimi errores in eam irrepserint. Hisce igitur, sive a Logiste lassitudine, sive typographi incuria profectis ig- noscant, obsecro, benevoli lectores: me enim tum infirma valetudo, tum rerum graviorum cura prepedivit, quo minus secundam his curam adhiberem. Vertm si hujus inventi usum eruditis gratum fore intellexero, dabo fortasse brevi (Deo aspirante) rationem ac methodum aut hune canonem emendandi, aut emendatiorem de novo condendi, ut ita plurium Logistarum diligentia, limatior tandem et accuratior, quam unius opera fieri potuit in lucem prodeat. NIHIL IN ORTU PERFECTUM.” I have seen a copy of the Canon Mirificus bearing the date 1614 on the title-page, but without this admonitio on the last leaf, NAPIER OF MERCHISTON. 413 we have already quoted from Dr Hutton’s pages. Henry Briggs himself took the charge of bringing out that translation in London, and wrote a preface to it, in which he claims nothing, hints no injustice done to himself, praises the author exceedingly, and adds, “ and if it shall please God (who besides his other mercies hath granted this honour unto the author to begin and thus far to accomplish this admirable work), further to grant unto him life and compe- tent strength, I doubt not we shall have the work so enlarged and perfected that we may use it, both with greater ease and with exactness unto the 10th place.” In 1617, Napier, in a letter to the Earl of Dunfermline prefixed to another publication, again asserts, without any qualification or contradiction, that he had invented the common Logarithms, and meant to publish the new method. He had arrived at his great invention in the progress of conquering the whole system of numbers. It was a chapter or a section only of a comprehensive work, and this, to a wonderful extent, he had already performed indepen- dent of the Logarithms, the importance and labour of which, however, occupied his last years and brought them too soon to a close. In the progress of this work, mechanical contrivances for relieving the difficulties of computing had not escaped him. From his extensive reading (in an age when books and those who loved them were rare in Scotland,) he gathered, that in Greece, and elsewhere, the abacus and other modes of palpable arithmetic had been in use for practical purposes. He saw that such contrivances were far beneath the dignity and power of intellectual operations, but his genius ne- glected nothing, so in passing he remodelled that chapter too, and enriched it with new stores. Both during the progress of the Canon Mirificus, and after- wards, he had contrived a variety of these methods, of which the most im- portant was RABDOLOGIA, or the art of computing by means of figured rods, better known by the name of Neper’s bones. These inventions he had not at first considered worthy of publication, but having communicated them to his friends, they were beginning to be known both in this country and abroad, and of course in danger of being pirated. The learned Alexander Seton, Earl of Dunfermline, was then Lord High Chancellor of Scotland, and the friend and warm admirer of Napier. At his instigation our philosopher collected the most important of his minor inventions in a profound Latin digest of vari- ous numerical properties. This elegant little volume, now rarely to be met with, he dedicated to the Chancellor by a Latin epistle, of which the following is the substance. 414 THE LIFE OF — To the most illustrious Alexander Seton, Earl of Dunfermline, Lord of Fyvy and Urquhart, High Chancellor of Scotland, &c. The difficulty and prolixity of calculation, (most illustrious Sir) the weari- ness of which is so apt to deter from the study of mathematics, I have always, with what powers and little genius I possess, laboured to eradicate. And with that end in view, I published of late years the Canon of Logarithms, wrought out by myself a long time ago, which, casting aside the natural numbers, and the more difficult operations performed by them, substitutes in their place others affording the same results, by means of easy addi- tions, subtractions, bisections, and trisections. Of which Logarithms, in- deed, I have now found out another species much superior to the for- mer, and intend, if God shall grant me longer life, and the possession of health, to make known the method of constructing, as well as the manner of using them. But the actual computation of this new Canon, I have left, on account of the infirmity of my bodily health, to those versant in such studies ; and especially to that truly most learned man, Henry Briggs, public professor of geometry in London, my most beloved friend.* In the mean time, how- ever, for the sake of those who prefer to work with the natural numbers as they stand, I have excogitated three other compendious modes of calcu- lation, of which the first is by means of numerating rods, and these I have called RABDoLOGIA. Another, by far the most expeditious of all for multiplication, and which on that account I have not inaptly called the promptuary of multiplication, is by means of little plates of metal disposed ina box. And lastly, a third method, namely local arithmetic performed upon a chess-board. I was chiefly impelled, however, to the publication of this little work concerning the mechanism and use of the rods, not merely in consequence of finding that many were so pleased with them * « Difficultatem et prolixitatem calculi (vir illustrissime) cujus tedium plurimos a studio ma- thematum deterrere solet, ego semper, pro viribus et ingenii modulo, conatus sum é medio tollere. Atque hoc mihi fine proposito, Logarithmorum canonem, a me longo tempore elaboratum, supe- rioribus annis edendum curavi,” &c. “ quorum quidem Logarithmorum speciem aliam multé pre- stantiorem nunc etiam invenimus, et creandi methodum, una cum eorum usu (si Deus longiorem vite et valetudinis usuram concesserit) evulgare statuimus: ipsam autem novi canonis supputa- tionem, ob infirmam corporis nostri valetudinem, viris in hoc studii genere yersatis relinquimus; imprimis vero doctissimo viro D. Henrico Briggio, Londini publico Geometrie Professori, et amico mihi longe charissimo,” &c, NAPIER OF MERCHISTON. 415 that they are already almost common, and even carried to foreign countries ; but because it also reached my ears, that your kindness advised me so to do, lest they should be published in the name of another, and I be compelled to sing with Virgil, Hos ego versiculos feci, &c. And. this very friendly counsel from your Lordship ought to have the greatest weight with me; though most assuredly, but for that, this little book of rods (to which the other two compendious methods are added) would scarcely have seen the light. If, therefore, any thanks be due from the stu- dents of mathematics for these little books, they all belong to you as your just right, my noble Lord, to whom, indeed, they must spontaneously fly, not only as patron, but a second parent: especially since I am assured that you have done these rods of mine such high honour, as to have them framed not of vulgar materials, but of silver. Accept, therefore, my Lord, in good part, this small work such as it is; and, though it be not worthy of so great a Meceenas, take it under your patronage as a child of your own. And so I earnestly pray God to preserve you long to us and the state, to preside over justice and equity. “ Your Lordship’s most obedient, * JOHN NAPIER, “ Baron of Merchiston.” The date of the volume to which this letter is attached is 1617, and Napier died upon the 4th of April in that year. This unfortunate bereavement left the men of letters, in his own country at least, very anxious lest they should also lose those methods of constructing Logarithms which he had promised. His son Robert, a young man of a singular turn of mind, but somewhat imbued with the habits and talents of his father, was, however, naturally backward in attempting the difficult task of preparing for publication the most profound of his father’s works, which had not been left in the state that the author meant the public to see them. Napier himself, who long delayed the publication of the Canon, in various passages evinces anxiety as to its recep- tion, and holds out only a conditional promise of giving the world the secret of constructing it. The most important works were then but slowly spread abroad ; and during the few remaining years of his life, our philosopher had not received sufficient assurance of the approbation of foreign philosophers to 416 THE LIFE OF make him hasten to publish the Constructio. But Henry Briggs was still indefatigable in the cause. About the close of the same year in which Napier died, he published, under the title of Logarithmorum Chilias Prima, the first part of that work which he had been on the eve of submitting to Napier in person for the third time. It is in the preface to this that the words occur, “ Why these Logarithms differ from those set forth by their most illustrious inven- tor, of ever respectful memory, in his Canon Mirificus, 1 Is TO BE HOPED, his posthumous work will shortly make appear.” By those capitai letters, Dr Hutton means to call particular attention to the fact, that Briggs “ modestly hints” that justice ought to be done to himself !—a view of the matter deficient both in sense and dignity. Since Briggs first expounded the Logarithms at Gre- sham College in 1615, his days and nights had been spent in admiration of Na- pier. As for hisown share in the improvement, he had announced it to a London audience the moment it struck him. Had that been the object of his solicitude, it was secured so far, and he might have published it at any time, in any other shape he pleased. But such an idea never entered his mind. He had long ago yielded even that merit to the superior sagacity of the author himself, and now he was only expressing, in common with other philosophers, a hope that the world would not be deprived by Napier’s death of the promised method of Con- struction. Robert Napier was hesitating about the publication some time after- wards, and did not produce it until the year 1619. But in the year of Napier’s death, Kepler first saw the Canon Mirificus at Prague when he was too preoccu- pied to pay it much attention. In the year 1618, he looked at it more closely, and his very soul was stirred within him. He displayed the same enthusiasm in Germany that Briggs did in England, and would, like him, willingly have fal- len at Napier’s feet. His Ephemerides, his Rudolphine Tables, and all his calculations were to be remodelled upon the new system; for the rest of his life, Kepler was the very Don Quixote of Logarithms ; and, if an old phi- losopher within the four corners of Germany dared to croak a doubt as to their purity, Kepler shivered his spear on him in an instant. It may be supposed that one so ardent would not be long of communicating in some shape or other with the author. So the German, having struggled to master the subject, by plunging as usual into a sea of calculation, sat down to relieve his overflowing mind in a letter addressed to John Napier, who for two years had been in his grave. To this characteristic epistle we shall return. It may be mentioned here, however, that Kepler therein expresses the greatest anxiety to see the 4 NAPIER OF MERCHISTON. 417 method of construction ; and he adds, that such being the earnest desire of himself and other philosophers in Germany, Napier was bound to redeem his pledge given to the public on those conditions. Now it was in 1619, the year of Kepler’s letter, that our philosopher’s posthumous work appeared, and it is not unlikely that this letter, or some previous report of the warm admiration of Ursin and Kepler, had the greatest influence in bringing it to light. If he had lived to publish his own work, there is no doubt that he would have men- tioned Briggs in the most affectionate terms, as is evident from the manner in which he refers to him elsewhere. Independently of being a gentleman and a philosopher, he entertained punctilious views upon the subject of literary property, * and in the letter to the Earl of Dunfermline, while taking unqua- lified credit for the invention of the new method of Logarithms, he speaks of the risk of literary piracy as a reason for publishing his Rabdologia. Are we to take from Dr Hutton the mean view of this illustrious man, that in the very same letter he was pirating from his “ amico longe charissimo ?” But this author has also said, that “in the posthumous work published by Lord Napier’s son in 1619, the alteration is again adverted to, but still without any mention of Briggs.” This is equally unjust to Robert Napier ; the assertion is not borne out by the fact, and we must exonerate the Rosicrucian son of our philosopher, by quoting the substance of the very elegant Latin address with which he prefaces his father’s fragments. “ Some years ago, my father, of ever venerated memory, published the use of the wonderful Canon of Logarithms ; but the construction and method of generating it, he, for certain reasons, was unwilling to commit to types, as he mentions upon the seventh and the last pages of the Logarithms, until he knew how it was judged of and criticised by those who are versed in this department of letters. But since his death, I have been assured from undoubted authority, that this new invention is much thought of by the most able mathematicians ; and that nothing would delight them more than if the construction of his wonderful Canon, or so much at least as might suffice to illustrate it, were published for the benefit of the world. Although, therefore, it is very manifest to me that the author has not put his last finish * The French translator of the Plain Discovery thus addresses his readers in a conspicuous ad- vertisement. ‘ D’autant que j’ay mis quelques additions en plusieurs endroits tant du premier que du second Traicté du Sieur de Merchiston sur I’ Apocalypse, et que sa volonté est que je marque ce que j'ay adjousté, afin qu'il soit separé d’avec ce qui est de luy: le lecteur sera adverti que ce qui trouvera en marge marqué de cette estoille*, est de moy, et non de l’autheur de ce livre.” 3G 418 THE LIFE OF. to this little work, yet I have done what in me lay to satisfy their laudable desires, as well as to afford some assistance, especially to those who are weak in such studies, and apt to stick at the very threshold. I doubt not, however, that this posthumous work would have seen the light in a far more perfect and finished state, if to the author himself, my dearest father,—who, according to the opinion of the best judges, possessed among other illustrious gifts this in particular, that he could explicate the most difficult matter by some sure and easy method, and in the fewest words,—God had granted a longer use of life. You have, then, (benevolent reader,) the doctrine of the construction of Logarithms—which, here, he calls artificial numbers, for he had this treatise beside him composed for several years before he invented the word Logarithms, —most copiously unfolded, and their nature, accidences, and various adap- tations to their natural numbers, perspicuously demonstrated. I have also thought good to subjoin to the construction itself a certain appendix, concern- ing the method of forming another and more excellent species of Logarithms, to which the inventor himself alludes in his epistle prefixed to the Rabdolo- gia, and in which the Logarithm of unity is 0, The treatise which comes last is that which, tending to the utmost perfection of his logarithmic trigo- nometry, was the fruit of his latest toil, namely, certain very remarkable pro- positions for resolving spherical triangles, without the necessity of dividing them into quadrantal or rectangular triangles, and which are absolutely gene- ral. These, indeed, he intended to have reduced to order, and to have suc- cessively demonstrated, had not death snatched him from us too soon. I have also published some lucubrations upon these propositions, and upon the new species of Logarithms, by that most excellent mathematician, Henry Briggs, public professor in London, who undertook most willingly the very severe la- bour of calculating this Canon, in consequence of the singular affection that existed betwixt him and my father of illustrious memory,—the method of con- struction and explanation of its use being left to the inventor himself. But now, since he has been called from this life, the whole burden of the business seems to have fallen on the shoulders of the most learned Briggs, as if it were his peculiar destiny to adorn this Sparta.* In the meanwhile, reader, enjoy these labours such as they are, and receive them in good part. Farewell. “ ROBERT NEPER,” * « Qui novi hujus Canonis supputandi laborem grayissimum, pro singulari amicitia que illi cum NAPIER OF MERCHISTON. 419 It will be observed, that in all the notices of the new system of Logarithms, either in our philosopher’s own words or his son’s, there is not the slightest indication of any competitor for the invention. If a doubt upon the subject existed then, the story which Briggs so candidly told in 1624 would have been told by the Baron himself. Had he done so precisely in the words used by the Savilian professor, and without contradiction, it must have been re- ceived as complete evidence of his invention of the common Logarithms. But Napier’s right was undisputed. The date of his posthumous work is 1619, two years after his death, and two years after those expressions used by Briggs in the preface to his Chilias Prima, which have been interpreted into a modest hint for the protection of his literary property. Yet he attests the truth of Robert Napier’s statement, by adding his own lucubrations to the work, and aiding most materially its publication. He then proceeded in his Herculean task of calculating and illustrating Napier’s new system, as the pre- face to the Constructio intimates, and in 1624 produced his own greatest work the Arithmetica Logarithmica. There is very interesting evidence still extant that the most perfect cor- diality prevailed betwixt Robert Napier and Briggs long after our philoso- pher’s death ; and that the Savilian professor, in the progress of his great work, continued to call to his aid as much of the genius of the master he had lost as he could command. Napier left a mass of papers, including his mathematical treatises and notes, all of which came into the possession of Robert as his father’s literary executor. When the house of Napier of Cul- creugh was burnt, these papers perished, with only two exceptions that I have been able to discover. The one is the manuscript treatise on Alchemy by Robert Napier himself; but the other is a far more valuable manuscript, being entitled, “ The Baron of Merchiston, his booke of Arithmeticke, and Algebra; for Mr Henrie Briggs, Professor of Geometrie at Oxforde.” This very curious work was presented to Francis V. Lord Napier, by the then Napier of Culcreugh, probably at the time his Lordship contemplated writing a life of his great ancestor, and it has lain in the Merchiston charter-chest patre meo L, M. intercessit, animo libentissimo in se suscepit ; creandi methodo et usuum expla- natione Inventori relictis.

Reserving a more particular account of it for the supplamentary review of our philosopher’s mathematical works, we may notice here, that it is of great length, beautifully written in the hand of his son, who mentions the fact, that it is copied from such of his father’s notes as the transcriber considered “ orderlie sett doun.” It is material to observe in reference to what we have been considering, that it bears expressly to have been written out by Robert Napier for Henry Briggs, and after the latter had been appointed to the Savilian chair, which ' appointment took place in the year 1619. It seems not unlikely that it had been sent to Briggs while he was in the progress of his great work, and we shall have to consider afterwards a very remarkable and interesting co- incidence in reference to that idea. But we have thus unquestionable evi- dence, that from the time when Briggs first expounded the Canon Mirificus to his scholars at Gresham House, to the period when he published the Arithmetica Logarithmica, he continued to regard our philosopher as his guide, and no cloud but that of death ever past betwixt them. The noble work of Henry Briggs becomes doubly interesting when we view it, not merely as a stu- pendous monument of his own mathematical powers and industry, but as con- taining more or less of the reflection of the mind of his master. Asif to confirm Robert Napier’s classical allusion, Briggs, not merely in his preface, but in the dedication, and on the title-page of that work, anxiously announces it as the fruits of Napier’s genius, expanded and illustrated according to Napier’s own desire. It is dedicated, like the Canon Mirificus, to Prince Charles, whom the courtly professor thus addresses :—“ Most potent Prince, not the rarity and beauty, not the mingled usefulness and infinite delectation of the theme, could have persuaded me to the presumption of dedicating these, my mathe- matical commentaries, to your royal highness, had not that illustrious man, John Napier, Baron of Merchiston, the Inventor of these Logarithms, when he first brought them to light committed the patronage of them to your well known authority and virtue. In respect of that circumstance, indeed, even these, however inferior they may appear at the first glance, shall not be unworthy to be seen and handled by all mathematicians,—especially since it has pleased God (after bestowing the light of the Gospel upon the world) to communicate to us many inventions useful to human life, of which there were no vestiges among the GN ca that, as of these what appertains NAPIER OF MERCHISTON. 421 to mathematics holds the highest rank, so in the mathematics Logarithms are supereminent, whether we regard the penetration of the discovery, or the excellence of its practical application,” &c. * All the distinction which Briggs had reached before his companionship with Napier was nothing compared to what he attained afterwards, though he was about sixty years of age when he first visited Merchiston. In 1592 he was a lecturer at Cambridge. When Gresham College was founded in 1596, his high mathematical reputation obtained for him the first professorship of geometry there. In 1609 he was honoured with the correspondence of Usher. In 1610 he was “ discoursing concerning eclipses” with that prelate, and anxiously watching and waiting for the works of Kepler. By this time he had only published “ A Table to find the Height of the Pole, the mag- netic declination being given,” besides tables for the improvement of naviga- tion; and he was generally distinguished as the best mathematician in England. But in 1614 a new path was opened to him. Then, said he, ** Napper, Lord of Markinston, hath set my head and hands a work with his new and admirable Logarithms ;” and from that moment, old as he was, his career of fame may be said only to have commenced, for its proudest orbit was round the sphere of Napier. In 1615 he staid a month at Merchiston, discoursing of numbers. He had not contemplated so long a visit ; but hesi per integrum mensem,”’—he found a mind that fascinated him, and he drunk deeply of its lore. In 1616 he repeated his visit. In 1617, again, his anxious steps were turned northward, but the star of his attraction had dis- appeared. In that year, however, Briggs published “ Logarithmorum Chi- lias Prima ;” and in 1619, “ Lucubrationes et Annotationes in Opera Pos- thuma J. Neperi.” He was then appointed the first Savilian Professor of Geometry at Oxford. There, in Merton College, he devoted his gray head to the arduous computation of Logarithms. In 1624 he published his “ Arith- metica Logarithmica.” In 1630 he died, and his posthumous works, publish- ed shortly after, were all on the subjects he had discussed with Napier at * The title-page gives both the original invention and the new system expressly to Napier. «« Hos numeros primus inyenit clarissimus vir Johannes Neperus, Baro Merchistonii ; eos autem ex ejusdem sententia mutavit, eorumque ortum et usum illustravit Henricus Briggius, in celeber- rima Academia Oxoniensi Geometrie, Professor Savilianus.” Is this the language he would have used had he been, as alleged, suffering under the injustice of Napier for nine years ! 4.29 THE LIFE OF Merchiston, and that companionship aided most materially the memory he has left at Merton College, “ stupor mathematicorum.” But, says Dr Hutton, in his account of Henry Briggs, “ One of his suc- cessors at Gresham College, the learned Dr Isaac Barrow, in his oration there upon his admission, has drawn his character more fully ; celebrating his great abilities, skill, and industry, particularly in perfecting the invention of Lo- garithms, which, without his care and pains, might have continued an im- perfect and useless design.’* Nonsense, when skilfully mingled, seasons to advantage a Latin oration. But it was not fair in Dr Hutton thus gravely, in a philosophical work, to take Dr Barrow at his word. How shocked would Henry Briggs have been at the injustice,—how astonish- ed at the absurdity of this eulogy! Napier, who only required health and prolonged life to have added to his own invention all and more than his friend lived to accomplish, produced a work which nothing but the total submersion of letters could have rendered an imperfect and useless de- sign. His concluding words, in the Canon Mirificus, are far from being an exaggerated estimate of the boon he presented to the world. ‘ Now, there- fore,” says he, “ it hath been sufficiently showed that there are Logarithms, what, they are, and of what use they are; for with help of them, we have both demonstratively showed and taught, by examples of both kinds of trigo- nometry, that the arithmetical solution of any geometrical question may most readily be performed without trouble of multiplication, division, or extraction of roots. You have, therefore, the admirable table of Logarithms that was promised, together with the most plentiful use thereof, which, if (to you of the learned sort) I shall by your letters understand to be acceptable to you, I * Hutton’s Math. and Phil. Dict., Art. Briggs. As a defence for Dr Barrow, we have sought out his Latin oration alluded to, and here is the passage: “ Attestor tuum quod nostris agmen ducit in tabulis omni laude majus omnique encomio celebratus nomen, doctrina, acumine, solertia prestantissime Briggi. Tu qui Logarithmorum illud preclarissimum artificium non tua quidem (quod ad gloriam maxime Secerit) reperisti fortuna, sed, quod e@qué laudem meretur, consum- masti industria atque omnibus numeris absolvisti, quod inutile forsan adhuc et imperfectum ja- ceret opus fundimenti sui rudibus obvolutum, nisi subtilissimi tu lunam ingenii et indefesse dili- gentiam manus adhibuisses.”—Jsaact Barrow, Opuscula. Dr Hutton takes care not to notice that the compliment in this passage is, by an admission a little ludicrous, greater to Napier than to Briggs. We shall not translate it, as Dr Barrow never meant his Oration to be done into English. NAPIER OF MERCHISTON. 423 shall be encouraged to set forth also the way to make the table. In the meantime, make use of this short treatise, and give all praise and glory to God, the high Inventor and Guider of all good works.”* And Dr Hutton himself, with the inconsistency of error, confirms this estimate, when he calls the Canon Mirificus “a perfect work on this kind of Logarithms, contain- ing, in effect, the Logarithms of all numbers, and the Logarithmic sines, tan- gents, and secants for every minute of the quadrant, together with the de- scription and uses of the tables, as also his definition and idea of Logarithms.”+ By that work alone the science of trigonometry was emancipated. It was the opening of a fountain that could never run dry, and the sage who struck the rock was he who improved the source. Had Henry Briggs never breath- ed, England would have lost a philosopher, and Napier a friend, but the Logarithms would have been as they are. There were Gunter, Gellibrand, and Speidell in England, Wingate and Henrion in France, Ursin and Kepler in Germany, Vlacq in Holland, Cavalieri in Italy, names all identified with the promulgation of Logarithms, and contemporary with their author. If Napier’s system can be imagined to have escaped these contemporaries, would Mercator, Wallis, Gregory, Halley, Sir Isaac Newton, Cotes, Taylor, Leibtnitz, Euler, Wolff, Maclaurin, names all identified in their brightest phases with the philosophy of Logarithms, have suffered the Canon Mirificus to disappear with the fragment of Byrgius ? I have been anxious to place this modern depreciation of Napier’s character and merit in its proper light for several reasons. It disturbed the view of his lofty and spotless character, and rendered no longer true his eulogy by the most philosophical and elegant historian of England,—that he is “ the per- son to whom the title of a GREAT MAN is more justly due than to any other whom his country ever produced.” It destroyed the beautiful picture of friend- ship betwixt him and Henry Briggs; and it mutilated an important feature in the history of his great discovery. The system he created was susceptible of one, and but one, material improvement. If it received that, too, from him- self, it was essential to prove the fact even had his honour not been involved in the question. No other instance can be pointed to in the progress of human * English translation of tne Canon Mirificus, 1616. P. 89. + Hutton’s History of Logarithms, p. 24. edit. 1785. 424 THE LIFE OF knowledge, where an impulse so great, and a power so unlimited, have result- ed from the premeditated achievement of a solitary individual, whose system was perfected at once and without a rival. His improvement superseded his original Canon, but that, so far from perishing, has found its apotheosis in the higher calculus. To distinguish these systems, the illustrious name of Briggs may be justly associated with the common Logarithms, because, “ Sparta hec ornanda il sorte quadam obtigisse videtur.” But the modern expressions, which speak of “ the very great improvement that necessarily ensued on Briggs’ alteration of the Logarithmic Base ;” * and of “ Naperean Logarithms,” as opposed to the “ system of Briggs,” are inconsistent with the history of the invention, and must be met with the reply, that in respect of system, ALL LOGARITHMS ARE NAPEREAN.” + The spot where our philosopher Jies interred is not certainly known, and the tradition of his descendants, that he was buried in the church of St Giles, (where some of the family monuments still exist) has been lately questioned. The parish records of Scotland are not in a state to solve the doubt, nor have I been able to obtain any evidence on the subject which seems so good as that contained in a letter by Professor Wallace to the Antiquaries of Scotland. Af- ter passing an enthusiastic encomium upon the character and genius of our philosopher, and noticing the turbulent and unpropitious atmosphere in which he held his being, the professor proceeds to record this evidence : “ ON THE BURIAL PLACE OF NAPIER OF MERCHISTON. * It is no doubt from the combination of these causes, that although we know the exact period when one of the greatest men that Scotland, or even Europe, ever produced, left the stage of mortal existence, yet, with the exception of * Woodhouse. Treatise on Trigonometry, p. 171. + It was time to clear up this matter, for of late years the tables have been completely turned upon the Inventor of Logarithms. In the “ Dictionary of General Knowledge, by George Crabb, A. M. 1830,” I find Briggs thus recorded, “ Briggs, an English arithmetician, the Jnven- tor of Logarithms !” and in the same volume, “ Napier, a Scotch arithmetician, improved the system of Logarithms /!” So the Library of Entertaining Knowledge says, that our philosopher signed himself “ Peer of Merchiston ;” and the Dictionary of General Knowledge says he was not the inventor of Logarithms. NAPIER OF MERCHISTON. 425 what I am presently to communicate, there is no record, so far as I have been able to discover, of the place where he was buried. It is in the recollection of the older inhabitants of Edinburgh, that when the church of St Giles was skirted on the north side by a fringe of wooden erections occupied as shops, there was to be seen, on the front of the church, a stone in the wall, with this inscription : Pe i as a FAM. DE NEPERORVM INTERIVS HIC SITUM EST. * “ From this it was evident that some of the family of Napier were interred in the church, and it was commonly believed that John Napier, the inventor of Logarithms, must have been one of them. ** In support of this opinion, Maitland, the author of the History of Edin- burgh, has always been quoted. He says, ‘'The following inscription is fixed on the outside of the northern wall of the choir of the church of St Giles, in commemoration of the illustrious and ever memorable Lord Naper, Baron of Merchiston, inventor of the Logarithms, whose remains were interred in the choir of the church. Now, although no monument can add to the fame of this great man, he being most gratefully and honourably remembered in the works of the learned in all parts of Kurope as the author of that most curious and useful art, I have nevertheless chosen to point out the place of his inhumation by the said humble inscription.’ Another writer on the history of Edinburgh, Arnot, says, ‘ In different quarters of this church (St Giles) there are monu- ments of the celebrated Lord Napier of Merchiston.’ “ T think it probable that Arnot followed Maitland in saying that the in- ventor of Logarithms was buried in St Giles’; and also that the late Earl of Buchan, who says the same thing in his Life of Napier, had no other authority. I have consulted the very ingenious John P. Wood, Esq. the editor of the se- cond edition of Douglas’s Peerage, who, in his additions to that work, agrees with these writers in saying that Napier was buried in St Giles’; but I find * The attention and taste of Mr Burn, who renewed the church, have paid due honour to this old monument, which after undergoing various chances and changes, is now restored to its origi- nal position in a niche on the east side of the north door of the church. The arms above the in- scription are the combined shields of Napier of Merchiston and Napier of Wrighthouses, but of what date I have not been able to determine. The families were connected by marriage in 1513, as I have elsewhere noticed, and may at that time have had a joint burial place at St Giles. The stone has every appearance of being much older than the time of the philosopher.—Author. 3H 426 . THE LIFE OF that he had followed the Earl of Buchan. On the whole,,then, the popular opinion, which I found was also the belief of the present family of Napier when I first brought forward the question, has no other foundation than the assertion of Maitland; and his opinion seems to have been formed merely from the inscription on the stone, formerly on the front of the church, but taken down and placed in the inside by Mr R. Johnston, a zealous preserver of the antiquities of Edinburgh, at the time the Luckenbooths were demolish- ed. It is now restored to its first position, and would certainly be contem- plated with veneration if it could be proved to be the genuine monument of the celebrated Napier. “I have good reason, however, to believe that the inventor of Logarithms was not buried in St Giles’ church, but, on the contrary, that he was buried in the old church of St Cuthbert, which has been long demolished, and replaced by the present church on nearly the site of the former. “ My authority for this belief is unquestionable: It is a Treatise on Trigo- nometry, by a Scotsman, James Hume of Godscroft, Berwickshire, a place still in possession of the family of Hume. The work in question, which is rare, was printed at Paris, and has the date 1636 on the title-page ; but the royal privilege, which secured it to the author, is dated in October 1635, and it may have been written several years earlier. In this treatise (page 116) Hume says speaking of Logarithms, ‘ L’inwenteur estoit un Seagneur de grande condition, et duquel la posterité est aujour@huy en possession de grandes dignitéx dans le royaume, qui estant sur Cage, et grandement trauaillé des gouttes* ne pou- uait faire autre chose que de sadonner aux sciences, et principalment aux ma- thematiques et a la logistique, a quoy il se plarsoit infiniment, et auec estrange peine, a construict ses Tables des Logarymes, imprimees a Edinbourg en Pan 1614, gui tout aussitost donnerent vn estonnement a tous les mathematiciens de Europe, et emporterét le Sieur Biggs ( Briggs), professeur a Oxford, @ Angleterre en E’scosse pour apprendre de lui cette admirable inuention de construire les Logarymes, et Cayant enseigné a. construire vne nouuelle espece de Logaryme, + lui laissa ceste charge pour les faire apres sa mort, ce quil fit comme on le voujouit aujourdhuy par toutes les boutiques de libraires : Tl mourut Can 1616, et fut enterré hors la Porte Occidentale a’ Edinbourg, dans U Eglise de Sainct Cudbert, * I have not found it elsewhere recorded that our philosopher suffered from gout.—Author. + This is of more importance than the evidence of his burial-place ; it shows that Briggs was not considered the inventor of the new system of Logarithms.—Author. NAPIER OF MERCHISTON. 427 “ Here we have a direct assertion that Napier was buried without the West Port of Edinburgh, in the Church of St Cuthbert; and this is made not more than eighteen years after his death, which happened 3d [4th] April 1617 (not 1616, as stated by Hume.) Besides, this circumstantial declaration is made by Napier’s countryman and contemporary, perhaps his personal friend ; * at any rate, by one who had good means of knowing the truth, and who seems to have taken a deep interest in Napier’s invention, and in every thing con- nected with him. . “ Further, I would add, that the probability of the thing gives a weight to Hume’s testimony, which, however, it does not require; for Merchiston, the residence of Napier, was in the parish of St Cuthbert ; and nothing is more reasonable than to suppose that he would be buried in his parish church.” + It is a mistake, though recorded by Dempster and Dr M‘Crie, to suppose that Napier’s mathematical pursuits led him to dissipate his means. No man attended more strictly and conscientiously to his worldly affairs and numer- ous family. From his will it appears that, besides his great estates, the per- sonal property he left at his decease amounted to a large sum, and suffered little diminution from his debts, which were chiefly the current wages of his domestic and farm-servants. This interesting document has hitherto escaped the search of antiquaries, and it will gratify most readers to know its contents. “ Tur WILL OF NAPIER OF MERCHISTON. “ The Testament Testamentar and Inventar of the guidis, geir, sowmes of money, and debtis pertening to umquhile, the rycht honorabill Jon Naipper of Merchinstoun, within the parochine of Sanctcuthbert and schirefdome of Edinburgh, the tyme of his deceis ; quha deceist upon the fourt day of Appryle the yeir of God i™ vi and sevinteine yeiris, { ffaithfullie maid and gevin up be Agnes Naipper, dochter lawfull to the defunct, only major for hir selff, * His personal friend would not have referred Napier’s mathematical studies to his old age, and being troubled with gout.— Author. + On the Burial-Place of Napier of Merchiston, by William Wallace, A.M.

Henry Briggs, too, was on the eve of paying him a third visit. Of his last illness I have not been able to ascertain any farther particulars than that he had been for some time in a declining state of health, worn out, as we may gather from his own expressions already quoted, with constant and laborious studies. If the author of the old treatise on trigonometry can be relied upon, to this failure of his bodily strength was added the torture of the gout. But his latest mental effort proves that his mind was all powerful to the last. His character — may be told in few words. No purer heart ever ceased to beat, no gentler spirit ever passed away, no finer intellect was ever extinguished, than when Napier of Merchiston died. His genius was in advance of his times, and isolated in his country. The departed light of Alexandria and the coming glory of England, seemed reflected upon him from the past and the future. He conquered where Archimedes failed ; he entered the loftiest paths of New- ton; and it shall be shown in the sequel, that if Napier’s life had been spared some time longer, England’s monarch of science might not have had so many laurels toreap. Yet is he scarcely remembered, for his genius reposes afar off, amid the wilderness of science, like a solitary lake unexplored by those who en- joy its waters in the valley.

Now, illustrious Baron, I accost yourself, apart indeed from all others,—as the subject, and your book, entitled Mirificus Logarithmorum Canon demands,—yet in this public manner, because my conference with you must interest all men of letters. » “ That another year has been added to my delays is owing to the concurrence of peculiar circumstances in this year, besides the general causes which have hitherto impeded me. Some of these are of public notoriety, such as wars and comets,—others I have already spoken of, or alluded to in the preface to my Ephemerides for 1617 and 1619, which appeared in 1618; namely, the publication of five books of the Harmonice Mundi ; which publication alone, not to mention the previous lucubrations, fully occupied me for a complete year. It is finished, however,—praise be to the Almighty Harmoniser of the Universe, despight the roaring, and raging, and at intervals, horridly bluster- ing of Bellona, with her guns, and her trumpets, and her rattling drums. So * Kepler was not aware of Napier’s death two years after that event, which shows how retired was our philosopher's situation in reference to the world of letters. Lord Buchan says, “ Kepler dedicated his Ephemerides to Napier, which were published in the year 1617.” His Lordship had never seen the dedication, however, which is the above letter dated in 1619, prefixed to the Ephemeris for 1620. The work seems to be very rare. I have never been able to see a copy, but there is one in the Bodleian Library, Oxford; and my best thanks are due to Dr Bulkeley Bandinel for sending me from thence an accurate transcript of the letter. It would have been a valuable addition to Mr Drinkwater’s Life of Kepler, but that gentleman had not been aware of it. Nor had either Montucla or Delambre seen it, as is obvious from their histories. The latter seems inclined to adopt the idea that Kepler, while so much engrossed with Logarithms, was not par- ticularly anxious to acknowledge the author.— See Astronomie Moderne, Tome i. p. 507, &c. But the above completely exonerates Kepler from all paltry feeling on the subject. It also affords a most illustrious contradiction to the inutile forsan adhuc et imperfectum jaceret opus of Dr Bar- row’s oration. Never having previously met with a notice even of this interesting letter, I have given it entire in the Appendix, and translated Py most popular passages above. NAPIER OF MERCHISTON. 433 that had not this direful goddess beset me both at home and abroad, as yet she does, and had it not been for certain tricks of the trade (as happened to me in the second part of the Hpitome or Doctrina Theorica, which has not been able to get through the press beyond the first page,) they who love to look deeply into the works of God’s hands, illuminated by immortal mind, might, at this autumn fair of Frankfort, have had copies both of the Harmo- nics, and of my Description of Comets, which now for three months has been sticking at Auxburg. “ But the chief cause that impeded my progress this year in framing the Ru- dolphine Tables, was an entirely new but happy calamity which has befallen a part of the tables I long ago completed, namely, THAT BOOK OF THINE, illus- trious Baron, which, published at Edinburgh, in Scotland, five years ago, I first saw at Prague, two years since. It was not then in my power to peruse it ; but last year, having met with a little book by Benjamin Ursin, (long my fami- liar, and now astronomer to the Margrave,) where, in a few words, he gives the substance of your work extracted from the book itself, then I knew what had been done. Scarcely had I attempted a single example, WHEN, TO MY GREAT DELIGHT, I BECAME AWARE THAT YOU HAD GENERALISED THAT PLAY OF NUMBERS, OF WHICH A VERY SMALL PARTICLE HAD FORMANY YEARS BEEN EMPLOYED BY MYSELF ; and which I had proposed to incorporate with my tables; especially in the matter of parallaxes, and in the minutes of duration and delay in eclipses ; of which method this very Ephemeris exhibits an ex- ample. I was aware, indeed, that this method of mine was only applicable in the solitary case of an arc differing in no sensible degree from a straight line. But or THis I WAS IGNORANT, THAT, FROM THE EXCESSES OF THE SECANTS, LOGARITHMS COULD BE CONSTRUCTED, WHICH MAKE THIS METHOD UNIVERSAL THROUGH ANY EXTENT OF ARC. Then I longed above every thing to know if in this little book of Ursin’s the Logarithms had been accurately investigated. Calling to my aid, therefore, Janus Gringalletus Sabaudus, my familiar, I ordered him to subtract the thou- sandth part of the whole sine; again, to subtract the thousandth part of that residue, and to repeat this operation more than two thousand times, until there remained about the tenth part.of the whole sine; but of the sine, from which a thousandth part had been subtracted, I computed the logarithm with the greatest care, beginning from the unit of that division which Pitiscus most frequently uses, namely, the duodecimal. The logarithm thus 31 ABA THE LIFE OF NAPIER OF MERCHISTON. computed, I arranged uniformly with the remainders of all the subtractions. In this manner I ascertained that there was no essential error in these logarithms ; though some little errors had crept in, either of the press, or in that minute distribution of the greater logarithms about the beginning of the quadrant. I mention this to you by the way, in order that you may understand how gratifying it would be to me at least, (and I should think to others,) if you would put the world in possession of the methods by which you proceeded, of which I make no doubt you have many, and most ingenious, at your hand. “ Now, let us come a little closer to your tables,” &c. &c. ‘“‘ That none may doubt, upon this artifice I have framed the present Ephe- meris, and therefore of right it is inscribed to you, illustrious Baron. Thus, of necessity, your Logarithms become a part of the Rudolphine Tables ; be- ing in the first place reprinted in my printing-office ; and so astronomers shall have cause to congratulate themselves upon my delays. If any better plan suggest itself to you, pray communicate it to me as soon as possible ; and this same request, which by private letters long ago I made to some pro- fessors of astronomy, I now publickly repeat to all of them.

Tue philosophy of Logarithms has been so thoroughly investigated by the many illus- trious authors already referred to, that it is unnecessary to attach an algebraic discussion, or analytical theory of Napier’s great invention, to his domestic memoirs. I shall attempt, however, to sketch the history of his mathematical studies, especially in reference to those points which appear to have been carelessly or inaccurately recorded. To this shall be added some very curious original matter from our philosopher’s unpublished ma- nuscripts, which cannot fail to interest even those who are deeply read in mathematics. The most popular English history of Logarithms mixes up, in one theoretical view, the Logarithmic properties of numerical progressions, observed for many ages before Napier’s time, with “the happy Invention of Logarithms.” * But any observations of the kind made by calculators between the time of the sage of Syracuse, and the sage of Scot- land, seem to resolve themselves into the celebrated theorem of the former, the history of which has been already given. + A more distinct arithmetical view, of the properties of that theorem, was of necessity obtained through the medium of Arabic or Indian notation, which Archimedes did not possess; but our own philosopher was not led to his inven- tion or discovery by the preparatory labours of others, or at least that aid was afforded him as much by Archimedes as by any one else. This can be easily rendered obvious. We shall suppose that a mere tyro in modern arithmetic, and one ignorant of geometry, endeavours to make himself master of the theorem in the Arenarius. In any geometrical progression from unity, represented by the letters, A, B, C, D, E, F, G, H, I, K, L, * Hutton. t See page 346, 436 HISTORY OF THE and of which A is unity, he finds from Archimedes, that, “ if any two of the terms be multiplied together, the product will also be a term in the same progression ; and its place will be at the same distance from the larger of the two factors that the lesser factor is from unity; and that its distance from unity will be the same, minus one, that the sum of the distances of the two factors from unity is distant from unity.” To relieve his attention, our tyro will naturally substitute actual numbers in place of the symbols used by Archimedes. Having mastered the meaning of a geometrical progression, he may be supposed to adopt the series most easy to multiply into such a progression, namely, 1, 10, 100, 1000, 10000, 100000, 1000000, 10000000, &c. where he obtains a proportional increase in the constant ratio of 10, simply by adding an additional cypher to each additional term. He may select the two nearest terms from unity to make his experiment, and will not be long in discovering, that 100 multiplied by 10, gives 1000, the fourth term in the progression, counting unity. His eye will tell him at once that 1000 is at the same distance from the larger factor 100, that 10, the lesser factor, is from unity. Nor will he have much greater difficulty in ascertaining that the united numbers of the places of the factors, counting unity, is equal to 5, and that the product sought is at that number, minus one, being the fourth term. So far the theorem is satisfactorily tested. But if the tyro, in repeating his attempts, should select terms at a greater distance from unity and each other, his eye will not so readily assist him to the fact of the respective distances. He would have to count the terms, which might naturally lead him to number them, thus : L4ar2 3 4 5 6 7 8 1, 10, 100, 1000, 10000, 100000, 1000000, 10000000. In this manner, he would soon arrive at the knowledge, that the mere addition of the two upper figures immediately above the two lower terms to be multiplied, will give a sum or figure in the upper line, pointing not to the actual product sought, but to the term immediately beyond it; and he would also easily detect, that the fact of its not pointing immediately to the product, was explained by the minus one, which forms a hitch, as it were, in the theorem of Archimedes. Now, supposing the tyro to possess some ingenuity, he will easily get rid of this inconvenience by numbering the distances in the geometrical series differently, and calling 10 not the second term in the series, but the first term after unity, or the first distance from unity; and this would seem the more accurate way of numbering, for 1 cannot be said to be at any distance from itself. He would then arrange them thus : 1, o2 3 4 5 6 7 1, 10, 100, 1000, 10000, 100000, 1000000, 10000000. According to this mode of numbering, he would find that the sum of any two figures in the upper line was a number in that same line directly over a term in the lower line, which would be the product of the two terms respectively below the added figures. After this step it would not be difficult, even for a tyro, to detect all the simpler operations with INVENTION OF LOGARITHMS. 437 the upper progression, affording the same results as the more complicated operations with the lower. In the case supposed, a rude and limited, and, we may add, useless table of Logarithms, is unconsciously formed ; the numbers composing the arithmetical series being truly Logarithms to the terms composing the geometrical. But no step of any value beyond what was demonstrated by Archimedes is thus accomplished. The theorem of the school of Alexandria has been viewed through the facilities of Arabic notation,—a logarithmic adaptation of numerical progressions has been very clearly brought out,—but the Loga- rithms are just as far as ever from being discovered. Yet the very arrangement and base of the common Logarithms is thus exemplified by a tyro’s translation of Archimedes’s theorem into Arabic numerals ! The fact is, that our system of notation is essentially Logarithmic; and the tyro might have even detected, in the simple algorithm, 1000, the very process he had gone through in testing the theorem of Archimedes. 1000 expresses that 1 has progressed three steps from right to left; the cyphers mark those steps, and therefore may be said to number them. ‘Then the Arabic system is in a decuple progression ; 7.e. each move of the advancing digit increases its value ten times its last value ; so.1000 is unit progressed from right to left in this order, 1000, 100, 10, 1. The values of each move are here noted ; and the steps themselves may be arranged and numbered, thus: 1 2 3 1, 10, 100, 1000. Here we are back again to the Archimedean theorem and Logarithms! It will be ob- served, that to number the last example is superfluous, for the cyphers perform that office. Again, it is equally superfluous to write the whole steps of the progression at full length, for the simple notation 1000 expresses all the steps. It is a short-hand exemplification of the most convenient system of Logarithms; the cyphers stand in place of the arith- metical progression, 1, 2, 3, &c. as adapted to the geometrical progression, 1, 10, 100, 1000, &c. and the whole is based upon the denary scale in use. But if this be true, it must follow that the mere addition of the cyphers in the Arabic scale will afford the same result as the multiplication of the terms? And such, indeed, is the case; for a thousand multiplied by ten thousand gives ten million: ten million is noted by unit moved to the left seven steps, i. e. unit with seven cyphers to the right. A thousand has three cy- phers, and ten thousand has four, which added, give seven. Write this out, and we have 1 2 3 4 5 6 vf 1, 10, 100, 1000, 10000, 100000, 1000000, 10000000. Now, 1000 multiplied by 10000 must give 10000000; for the numbers above the fac- tors are 3 and 4, which added, give 7, which number points to the product sought, 10000000. Thus we find that the Arabic system itself is essentially Logarithmic, and that the properties of the Archimedean theorem may present themselves to a very ordinary cal- 1000 10000 10000000 438 | HISTORY OF THE culator, upon a consideration of the simple notation 1000. Jam not aware that the most profound observers of numerical progressions before the time of Napier ever went a single step beyond what we have thus exemplified. They pointed out the effect of the adaptation of an arithmetical to a geometrical series of numbers in relieving the calculation of the terms of the latter series in a particular case. ‘They might vary the ease by choosing other ratios of progression, and examine their properties more mi- nutely, but none of them (supposing them as numerous as Dr Hutton assumes) ever con- ceived the possibility of making the principle embrace the WHOLE SYSTEM OF NUMBERS. That was “ the reason why tables of such artificial numbers were not sooner formed,” and by no means because they were not sooner wanted. If all numerical operations were performed upon the decuple progression itself, and by means of unit and cyphers, calculators would have an easy time of it, and children might lisp in Logarithms. But where is the advantage of knowing, that to mul- tiply 10000 by 1000 we need only add the cyphers, when we have, for instance, to multiply 4723 by 835? It takes some trouble to discover that the product of those fac- tors is 8943705, a number very little indebted to cyphers for its notation, and which is not to be obtained by reckoning and adding the steps of the factors’ digits. In other words, it required no great penetration to discover that this progression, 1, 10, 100, 1000, &c. or this, 1, 2, 4, 8, 16, &c. can have for their logarithms the whole range of na- tural numbers 1, 2, 3, 4, &c.; but where are the logarithms for the many terms be- twixt 1 and 10, 10 and 100, 100 and 1000, &c. or betwixt all the terms of any other geometrical progression ? Kepler, in one of his enthusiastic essays on the subject, writ- ten not long after Napier’s death, exclaims with testy irony against some jealous carping philosophers in Germany :—‘ Now what is this thing ? Of what use are Logarithms ? Why to be sure, of the very use that was declared ten years ago by the original inventor, Napier, and which may be conceived in three words. Wherever it happens in common arithmetic, and in the rule of three, that two numbers have to be multiplied together, in that case their Logarithms are to be added ; where a number has to divide another, the Logarithm is only to be subtracted from the sum of the Logarithms, so that in the one case the added, and in the other case the remaining Logarithm points out the number sought in either operation. ‘This, I say, is the use of Logarithms. But the featherless chickens of arithmeticians, greedy of facilities, and gaping with their beaks wide open at the mention of this use, as if to gorge every particular gobbet of my precepticles, were not to be satisfied in a work devoted to the fundamental demonstration of the Loga- rithms.” * The use thus characteristically announced by Kepler would have been far be- neath the observation of that lofty philosopher, but for its application to the whole sys- tem of natural numbers, from unity in infinitum ; and Kepler himself, in his letter to Napier, draws the mighty distinction which separates the Scotch philosopher from every calculator in the world who had previously considered numerical progressions, when he * Joannis Kepleri, Supplementum Chiliadis Logarithmorum. 1625, INVENTION OF LOGARITHMS. 439 says, ‘‘ Vix autem uno tentato exemplo, deprehendi, magna gratulatione, generale factum abs te exercitium tlud numerorum, cujus ego particulam exiguam jam a multis annis in usu habe- bam.” We may well believe, that if Kepler, as he tells us himself, did actually observe, and attempt to reduce to practice, logarithmic properties of numbers, without having the least conception of the Logarithms par excellence, and also that Stifellius, a most profound arithmetician, examined such properties still more minutely without forming that con- ception, there was a gulf which totally disunited those speculations from Napier’s inven- tion, however Dr Hutton may have been pleased to jumble the ideas together in his history. The fact is, that, from the undeveloped state of the power of Arabic notation at this early period of European science, the speculations referred to had an obvious ten- dency to check the conception of the Logarithms. ‘ The natural system of numbers, 1, 2, 8, 4, &c. composed an arithmetical progression, capable of being Logarithms to various sets of geometrical progressions. How, then, could that system obtain Logarithms adapted to itself throughout its infinite extent? Its nature would require to be changed from an arithmetical to a geometrical series, without losing any of its terms; and this involved a contradiction, and was clearly impossible! The system of Logarithms is founded upon ‘the correspondence of those different progressions. That system cannot exist as such, unless it be made applicable to the whole range of natural numbers. ‘The whole range of natural numbers are in arithmetical progression, and never can form a geometrical one. How are these facts to be reconciled ? ‘Here all the calculators in Europe stopt short except Napier. His mind, of an uncommon cast, enabled him to break in upon this enchanted circle of numbers with perfect success. The general conception he formed was that of two flowing points, generating magnitudes by infinitely small degrees, and so regulated in their respective motions, that in the one case, the successive incre- ments would be equal to each other; and in the other case, would differ proportionally from each other in an infinitely small degree. In the latter case, a geometrical progres- sion was conceived, into which, obviously, all the natural numbers 1, 2, 3, 4, &c. might be supposed to enter as terms, having the magnitudes generated in the former case for their arithmeticals. Napier knew, indeed, that the infinitely small ratios which he ima- gined to be generated betwixt the natural numbers, were an approximation merely, and never could equal the determined finite quantity; but he had the sagacity to perceive, that, in such an approximation, the difference or defect would become smaller than any assignable quantity, and therefore would not sensibly affect the calculations to which he meant the system to apply. ‘The two first chapters of the Canon Mirificus contain the developement of this beautiful idea, and no succeeding philosopher, though the most illus- trious have tried it, has ever afforded a clearer view of Napier’s method than his own statement, which is as follows :— 440 HISTORY OF THE * Cuap. 1—Or tHE DEFINITIONS. 1.Definition. —«*_4 [ine is said to increase equally, when the point, describing the same, goeth forward equal spaces in equal times or moments.

Therefore, in what proportion QS is cut in R, in the same proportion (by the 10 of the 6 of Euclid,) let a Z be cut in c; and so let 6, running from a to e in the first moment, cut off a c from a Z, the line or sine c Z remaining. And from this c Z let d, proceeding in the second mo- ment, cut off the like segment or part, as QR to QS, and let that be c d, leaving the sine dZ. From which, therefore, in the third moment, let 4 in like manner cut off the seg- ment de, the sine e Z being left behind.

An Admonition. ‘* Hitherto we have shewed the making and symptoms of Logarithms. Now by what kind of account or method of calculating they may be had, it should be here shewed. But because we do here set down the whole tables, and all his Logarithms with their sines to every minute of the quadrant, therefore passing over the doctrine of making Lo- garithms till a fitter time, we make haste to the use of them; that the use and profit be- ing first conceived, the rest may please the more being set forth hereafter, or else dis- please the less, being buried in silence. For I expect the judgment and censure of learned men hereupon, before the rest, rashly published, be exposed to the detraction of the envious.” * The abstract geometrical mode in which Napier promulgated his system was so per- fectly original, as to startle and disturb some of the High Priests of Science in Germany ; and although that promulgation was accompanied by a canon, which (to use Dr Hut- ton’s expressions) ‘‘is a perfect work on this kind of Logarithms, containing in effect the Logarithms of all numbers, and the logarithmic sines, tangents, and secants, for every mi- nute of the quadrant, together with the description and uses of the tables,” still some of the venerable sages of the 16th century, no less jealous than astonished, shook their gray heads at the auspicious dawn of the 17th, and refused the summons of Kepler to fall down and. worship the greatest era of science, as its sun first rose above the remote hills of un- lettered Scotland. ‘ When,” says Kepler, “in the year 1621, I: travelled into Upper Germany, and discoursed every where with those skilled in the mathematical sciences, * English translation of the Canon Mirificus. 1616. 5. Proposi- tion. 6. Proposi- tion. 444, HISTORY OF THE concerning the Logarithms of Napier, I discovered that they, of whose minds age had di- minished the activity, in proportion as it had increased the experience, were unwilling to admit this description of numbers in place of the usual canon of sines. ‘They said it was degrading to a professor of mathematics to show such childish exultation about any com- pendious method of numbers; and meanwhile to receive into practice, without even a legitimate demonstration, a form of calculus, which some day or other might betray into errors when least suspected. ‘They complained that Napier’s demonstration depended upon the fiction of a peculiar geometrical motion, whose slippery and unstable nature was inadequate to sustain the severe march of reason and demonstration. This (he adds) induced me to attempt to found a legitimate demonstration, not under the nature of lines, or motion and fluxion, or, so to speak, any other sensible quantity, but under that of ratios and abstract quantities,” &c. But even Kepler was wrong in this conces- sion, as is admitted in modern science; and the puerility of the objection urged by these venerable bigots might have been retorted by the exulting champion of Logarithms. ‘¢ Napier’s view of the subject (says Professor Playfair) is as simple and profound as any which after two hundred years has yet presented itself to mathematicians. The mode of deducing the results has been simplified ; but it can hardly be said that the principle has been more clearly developed.” ‘The opinion of the Newtonian age has in like manner been passed upon those commentaries of Kepler, in which he attempted a new demonstration of the Logarithms, and the judgment is, that even he only mystified the system of Napier, while professing to clear it, and at the same time drew his own purest principles from Na- pier’s code. ‘* Whether (says Delambre) these objections were suggested to Kepler or oc- curred to his own mind, they might have been easily answered. Itis true that the conside- ration of fluents, and fluxions of lines and points in motion, are quite extraneous to the sub- ject; but efface them all, and Napier’s calculations are not a whit the less substantial. From two numbers which are ina given proportion, subtract proportional numbers, and the re- mainder will be proportional. Subtract from 9 and 10, a tenth part of each, there remains 8.1 and 9, and you have 10: 9::9:8.1,9 xX 9=10 x 8.1= 81. Behold the fundamen- tal theorem of Napier: upon this principle he formed his preparatory tables. Extend these tables sufficiently, and you will there find numbers sensibly equal to all the natural num- bers, to the sines, and to every possible numerical quantity. ‘The process is only an ap- proximation. Napier admitted the fact: but whefe the limit of the error is known, it is al- ways permitted to disregard it: equally admissible is it to adopt a method so eminently com- modious : there is nothing puerile in adopting it with exultation: on the contrary, the de- sire to confine that conception to lines and hyperbolic spaces has something in it of pedantry. All the clearness, simplicity, and generality observable in the theory of Logarithms are the results of processes purely analytical or numerical ; and we owe whatever is obscure to extraneous considerations with which the system has been painfully alloyed. I would wish no better proof of the fact than the works of Kepler and Mercator. Who would dream now a days of studying in Euclid the theory of numbers and proportions ? These subtleties are more troublesome than useful, and time, which might be more profitably INVENTION OF LOGARITHMS. 445 and judiciously bestowed, is lost in demonstrating such conceptions.” Delambre far- ther remarks of the Chilias Logarithmorum ; “ Kepler lays down 30 propositions ; the most part of them appear fit for nothing but to swell the volume; the number was ne- cessary, however, in order to justify a kind of jew de mots in his dedication. The land- grave of Hesse, Philippe, had presented him with 30 pieces of silver, and he evinced his gratitude by dedicating a book to the landgrave containing 30 propositions. The dedi- cation is in Latin verse garnished with Greek words. The book and the dedication are in the taste of the times. Kepler then proceeds to construct his tables, but takes very good care not to employ his 30 propositions ; ix fact, he uses no theorem for which he is not indebted to Napier.’ * Such is the opinion of a philosopher, the hero of whose his- tory of science is, nevertheless, Kepler. But the most illustrious defence of Napier’s genesis of Logarithms is to be found in the Life of Sir Isaac Newton. ‘“ The notion of flowing quantities first proposed by New- ton, (says Professor Leslie as if in a day dream,) and from which he framed the terms flux- ions and fluents, appears on the whole very clear and satisfactory ; nor should the meta- physical objection of introducing ideas of motion into geometry have much weight. Mac- laurin was induced, however, by such cavilling, to devote half a volume to an able but superfluous discussion of the question.” + Yet the works either of Napier, Kepler, De- lambre or Maclaurin might have informed our professor that, whatever its merits or de- merits, the notion of flowing quantities was also Napier’s, and that the terms said to have been framed by Newton are to be found in the Canon Mirificus. °* Sié punctus A, a quo ducenda sit linea fluxu alterius puncti, qui sit B; fluat, ergo primo momento,” &c.t and from Kepler we learn that the same cavils against which Maclaurin philosophised had been urged against Napier. Maclaurin himself, in the very work referred to by Sir John Les- lie, has a chapter “ of Logarithms and the Fluxions of logarithmic quantities,” in which he observes, “ the nature and genesis of Logarithms is proposed by the inventor in a me- thod similar to that which is applied in this doctrine (Fluxions) for explaining the gene- sis of quantities of all sorts, and is described by him almost in the same terms.”§ We must now turn to the passage in Sir Isaac Newton’s work, where he announces the me- thod that led him to his great discovery. “¢ I consider mathematical quantities in this place not as consisting of very small parts, but as described by a continued motion. Lines are described, and therefore generated not by the opposition of parts, but by the continued motion of points; superficies by the motion of lines; solids by the motion of superficies; angles by the rotation of the sides ; portions of time by a continual flux; and so in other quantities. These genesis really take place in the nature of things, and are daily seen in the motion of bodies. And after this manner the ancients, by drawing moveable right lines along immoveable right lines, * Histoire de l’ Astronomie Moderne, p. 507 et infra. + Leslie’s continuation of Playfair’s Dissertation. t{ Canon Mirificus. § Maclaurin’s Treatise of Fluxions, Vol. i. p. 158. 446 | HISTORY OF THE taught the genesis of rectangles. Therefore, considering that quantities, which increase in equal times, and by increasing are generated, become greater or less according to the greater or less velocity with which they increase and are generated, I sought a method of determining quantities from the velocities of the motions or increments with which they are generated; and calling these velocities of the motions or increments Fluxions, and the generated quantities /luents, I fell by degrees upon the method of Fluxions, which I have made use of here in the quadrature of curves, in the years 1665 and 1666.” * Here Newton seems to have fallen insensibly upon the method of Napier, for I can discover no indications in all his works that he had ever seen the Canon Mirificus, however deeply he entered the theory which that canon created. But the minds of these great men were formed in the same mould, although belonging to very different ages. Con- stantly bent on conquering where the difficulty seemed greatest, whether it were the mysteries of prophecy or calculation, they attacked their subjects with the same wea- pons. Had Newton been placed in the situation of Napier, he would have attempted the Apocalypse, and invented the Logarithms. Had Napier possessed the algebraic calculus in the state that Newton took it up from the hands of Girard, Harriot, Cavalerius, Des- cartes, Roberval, and Wallis, he would have reached the discovery of Fluxions by the very path of Newton; for, as it was, we shall find that he was on the confines of the binomial theorem. But some of the mathematical magnates of the present century, while reviewing the Fluxions of Newton, and the method which led him to attach that nomenclature to his system, make no mention of Napier, + as if there was nothing inte- resting or worthy of attention in the coincidence. Yet so strong is it, that, when the personal friend of Newton, and the greatest mathematician after Napier that Scotland ever produced, set his powerful mind to expound the philosophy of Newton’s fluxionary method, he wrote a chapter “ of the grounds of this method,” which serves equally well to illustrate Napier’s Logarithms or Newton’s Fluxions. Nay, he adopts the very pro- positions, and nearly the language of Napier. Even Dr Hutton, who has shown himself no friend to our philosopher’s fame, observes, ‘‘ Napier’s manner of conceiving the ge- * Sir Isaac Newton’s Treatise of the Quadrature of Curves, &c. translated by John Stewart, A. M. Professor of Mathematics in the Marischal College, Aberdeen, 1745. + No one should review, even by the slightest sketch, the mathematical sciences, without naming Napier,—far less if that review be in a life of Newton, who was so deeply indebted to the Logarithms. But the remarkable coincidences of the theological studies, and geometrical modes of investigation pursued by these philosophers, render it doubly strange that Sir David Brewster does not once men- tion Napier in his Life of Newton. How striking, on the other hand, are the observations of Delambre in his History of Astronomy. “ Néper démontre que log sin A > (1 — sin A) et < (coséc A — 1). Il le prouve par ses Fluxions et ses Fluentes.”» Again, “ Képler promet une démonstration légitime ; il regarde donc comme insuffisante ou inexacte celle de Néper: il pouvait lui reprocher des longueurs, des inutilités ; il lui reproche, en effet, cette idée de fluxions, et de fluentes, gu’on a depuis reprochée a New- ton. Mais nous verrons que les principaux théoréms trouvés et démontrés par Néper, n’ ont pas été inu- tiles a la nouvelle demonstration.’ —Tome i, pp. 499, 507. { Colin Maclaurin. 4 INVENTION OF LOGARITHMS. MAT neration of the lines of the natural numbers and their Logarithms by the motion of points, is very similar to the manner in which Newton afterwards considered the generation of magnitudes in his doctrine of fluxions; and it is also remarkable, that in Art. 2 of the Habitudines Logarithmorum et suorum naturalium numerorum invicem, in the Appendix to the Constructio Logarithmorum, Napier speaks of the velocities of the increments or de- crements of the Logarithms in the same way as Newton does, namely, of his fluxions, where he shows that those velocities, or fluxions, are inversely as the sines or natural numbers of the Logarithms, which is a necessary consequence of the nature of the gene- ration,” &c. And Hutton mentions this more particularly afterwards, when he says, “ I shall here set down one more of these relations, as the manner in which it is expressed (by Napier) is exactly similar to that of fluxions and fluents, and it is this: Of any two num- bers ‘ as the greater is to the less, so is the velocity of the increment or decrement (in- erementi autdecrementi) of the Logarithms at the less, to the velocity of the increment or decrement of the Logarithms at the greater,’ that is, in our modern notation, as X :Y:: y to z, where z and y are the fluxions of the Logarithms of X and Y.” * We thus see that Napier’s method was not an accidental idea, indicative of a rude age and country, but one which the loftiest minds were the most apt to adopt. Logarithms mark one great revolution in modern calculation,—Fluxions another ; and surely the coincidence is not uninteresting that their immortal authors arrived at these discove- ries independently of each other, but by a train of thought identically the same. But New- ton, to use the expression of his latest biographer, was “ the leader of a mighty phalanx, —the director of combined genius,—the general who won the victory, and therefore wears the laurels.” Napier occupies a remote and solitary orbit, whose glory is all his own. Heattacked science precisely at the point where the adventure was most uninviting and most laborious; and he did so precisely at the time when the achievement was of the greatest consequence. Men thought that the utmost power of the Indian algorithm was already displayed in the ascending decuple scale ; and although some faint idea of Deci- mal fractions had been obtained, still, until Napier arose, the system of numbers was viewed falsely and in fragments, like the first appearances of the ring of Saturn through the rude telescope of Galileo. The Brahmins themselves never knew the value of the scale whose beautiful notation they transmitted to Europe. Wallis, the successor of Henry Briggs in the Savilian chair, and whose Arithmetic of Infinites gave the first impulse to Newton’s mind, observes, “ there are two very considerable improvements which we have added to the algorism of the Arabs since we received it from them, to wit, Decimal frac- tions and the Logarithms.” Keill, who succeeded Wallis as Savilian professor, and is dis- tinguished as the opponent of Leibnitz, has also remarked, “ The mathematicks formerly received considerable advantages, first by the introduction of the Indian characters, and afterwards by the invention of Decimal fractions; yet it has since reaped at least as much from the invention of Logarithms as from both the other two.” In short, there is no doubt that the great frame-work upon which the miraculous powers of modern calcula- * Hutton’s History of Napier’s Construction of Logarithms, pp. 42, 48. 448 HISTORY OF THE tion are reared, consists of three steps, the Arabic numerals, Decimal fractions, and the Logarithms. Now of these, Napier brought the second into operation, and created the last, at a time when other philosophers were engrossed with the fascinations of applicate science, and when physical research was soaring upon unruly wing in dangerous advance of the science of numbers. ‘This view of our philosopher’s fame deserves a closer con- sideration; and we must now glance at the circumstances under which he deliberately undertook to unfold the latent power of the Arabic, or rather Indian, system. We have reviewed, generally, in the preceding memoirs, the manner in which his great contemporaries of the continent were employed, and the resources they had obtain- ed from their predecessors. The desideratum of those times was a philosopher of the in- tellectual order of Tycho, Kepler, or Galileo, who, possessing also their ardour for the ad- vancement of science, would devote his whole power to conquer the tyranny of Logistic. One or two had made that attempt before Napier’s time; and although the fruits of their labours conferred honour even upon Germany, still the results prove that his success was beyond the grasp of their minds. Had our philosopher lived under those cloudless skies where the telescope was first applied; had his lot been cast in some of those countries where the sons of science excited each other in the opening path of phy- sical research ; and where, (to use the expressions which, in reference to those countries, Napier addressed to his own monarch,) royalty itself became “ the patron and protector of all zealous students, and an allower and acceptor of their godly exercises ;” he, too, might have exerted his powers of calculation in legislating for the stars, or in founding some department of science less abstract and retiring than the path he followed. As it was, however, he turned to the numeral system, where there was so much to do, and where he achieved all that remained to be developed. That he set himself deliberately to the task, we learn from his own accounts, both in the preface to the Canon Mirificus, and in his letter to the Chancellor, already quoted; and the same is repeated in his preface to the > 799? quod’? Igo: they are more simply written thus: .3, .24, .075. .00462 ; the number of figures after the point being always the same as the number of cyphers in the denominators. In decimal fractions, as thus written, the figures next the point to the right indicates so many tenths; the next so many hundreths, and so on. ‘Thus in the fraction .346 the figure 8 expresses 3 tenths, 4 denotes 4 hundreths, and 6, 6 thousandths. ‘The use of cyphers in decimals as well as in integers is to bring the significant figures to their proper places, on which their value depends, as cyphers when placed on the left hand of an integer have no signification, but when placed on the right hand increase the value ten times each; so cyphers when placed on the right hand of a decimal have no signification, but when placed on the left hand, diminish the value ten times each.” ‘Thus we see that Napier’s first conception and explanation of that * Constructio Logarithmorum, p. 6. How deep, and refined, and far in advance of his times, are the doctrines crowded into this single passage. INVENTION OF LOGARITHMS. 457 system, written many years before it came into universal practice, might be transferred verbatim into a treatise on the subject for the year 1834. It is remarkable that Sir John Leslie, in connecting Napier’ with the history of Decimal fractions, had not referred to the posthumous work rather than to the Rabdologia; for it was in the Constructio Logarithmorum, that the ordinary rules of calculation were first dis- played working with equal facility upon the descending side of the scale. Delambre ( Astronomie Moderne, p. 493, et infra,) was particularly struck with the fact, and I shall follow so far that illustrious philosopher’s profound exposition of the work in ques- tion. ‘* Napier,” says he, “ in his definitions, and even in his calculations, makes use of decimal fractions ; but only gives the notation without any rule of calculation. It is the earliest example of them I have met with,—it is a first step, and one of the greatest importance,” (i est de la plus grande importance.) Delambre then follows Napier through his method of calculating the terms of his geometrical progression, but takes the aid of modern algebraic symbols. It would occupy too much space here to give the process, for which the reader must be referred to Napier’s own work, or other recondite sources. After detailing it, Delambre exclaims, ‘‘ We here distinctly observe examples of subtrac- tion in decimal fractions.” Passing through some more of the calculations he again ex- claims, “ behold manifestly division in decimal fractions ;” and fnrther on he adds, “ I have already remarked that Napier is the first to afford the idea of the calculation of decimal fractions, a little more developed afterwards by Briggs.” Such is the hold that Napier has of Decimal fractions, a part of the system, ‘ which” says Playfair, “‘ completed our arithmetical notation, and formed the second of the three steps by which in modern times the science of numbers has been so greatly improved.” Of course the first step was Arabic numerals, and the ¢hird was the Logarithms; so when we take into consideration that decimals only came into active operation with the system of Logarithms, and that Napier is the first, who affords examples both of the calculation with decimals, and of their best notation, we may fairly say that his share in the develope- ment of the great Arabic system is as two to one. ‘The original algorithm, whose his- tory is lost in distant climes and long past ages, brought as it were the telescope to numbers. When Napier reversed the notation, and caused it to act in the opposite direction, he may be said to have added the microscope; and he did so while creating the last and greatest revolution in the system,—when to ceuc! he added that omnipotent word, which nor Greeks nor Brahmins knew, doyagiduoi.* How proud a contempla- * aeiOuor signifies numbers, acyae!80!, the ratios of numbers ; or, rather, the number of ratios, aéyav detfuéc. Napier compounded the word before his system was known, but subsequent to the date of his invention. Dr Minto says, “ the term Logarithm was first used by Napier after the publication of the canon in which he uses the term of numerus artificialis”’ (Buchan and Minto’s Life of Napier, p-43). This is an extraordinary mistake. In the Constructio Napier used the latter phrase, but a profound consideration of his own system led him to frame the term Logarithms before he published his canon ; and the first knowledge of the system that the world obtained was through that nomenclature which 3M 458 HISTORY OF THE tion for Scotland, to observe the most recondite department of science receiving its finest and most powerful expansions in the hand of a Scottish baron of the 16th century. It is singular, that while Dr Hutton, in the history commented upon, would lead his readers to suppose that the Logarithms had been attained by some natural transition from the observation of numerical progressions, in which many calculators were simultaneously engaged, he has elsewhere recorded another error, the very antipodes of the former, in which he supposes the Logarithms to have been viewed and reached through an algebraic medium which belongs to a period of science whose date is long after Napier. Our author, in his Mathematical Dictionary, (Exponent of a power, ) after stating that ex- ponents, as now used, are rather of modern invention,” and noticing the rude and cum- brous approaches made towards their present notation, finally traces that system to Des- eartes and Girard, both of whom, it must be observed, wrote after Napier was dead. He then adds: “ ‘The notation of powers and roots by the present mode of exponents, has in- troduced a new and general arithmetic of exponents or powers; for hence powers are mul- tiplied by only adding their exponents, divided by subtracting the exponents, raised to other powers, or roots of them extracted, by multiplying or dividing the exponent by the in- dex of the power or root. Soa’? x a =a*, anda} x at =a; a ~ a = a2, and a? +a4—az4; the 2d power of a’ is a’, and the 3d root of a° is a. This algorithm* of powers led the way to the invention of logarithms, which are only the indices or expo- nents of powers: and hence the addition and subtraction of logarithms answer to the multiplication and division of numbers; while the raising of powers, and extracting of roots is effected by multiplying the logarithm by the index of the power, or dividing the 39 logarithm by the index of the root.” ‘Thus we have two different accounts of the invention of Logarithms furnished by Dr Hutton. The one is, that many learned calculators, about the close of the sixteenth and the beginning of the seventeenth century, “‘ set themselves” to find the Logarithms through the numerical properties pointed out by Archimedes, and actually laid down all the necessary principles; so that “* many persons had thoughts of ‘such a table of numbers ;” though, he admits, “ the world is indebted for the first publication of Logarithms to John Napier.” Dr Hutton’s other account, however, is, that has stood the test of ages, and remains unchanged under every new application, and every refined ana- lysis of the Logarithmic power. The word of itself affords evidence, that, although Napier demonstrated his system by the geometrical means of fluxions and fluents, his consideration of the subject was just as arithmetical as Kepler’s, Delambre has well observed of Kepler’s method of proportions, “ ce systéme est celui de Néper—cette origine rend raison de la dénomination logarithmique qui signifie nombre des raisons ; mais cette dénomination est de Néper, ainsi que Videe qui la lui a fournie: rcyav agibuce.” * Dr Hutton’s own explanation of algorithm is; “the common rules of computing in any art; as the algorithm of numbers, of algebra, of integers, of fractions, of surds, &. meaning the common rules for performing the operations of arithmetic, or algebra, or fractions, &c.”” Now the arithmetic of powers and exponents had no existence until after Napier’s death, INVENTION OF LOGARITHMS. 459 the algorithm of powers, as that was established by Descartes and Girard after Napier’s death, and towards the middle of the seventeenth century ‘ led the way to the invention of Logarithms!” That we may clear up this matter to the general reader, it is neces- sary to say a few words of powers and exponents,—a doctrine which derives its whole ef- ficacy from its system of notation. The product of any number multiplied by itself is called a power of that number. Thus 9 is a power of 3, because three times three is nine. The multiplication by the same number may be prolonged to any extent, and all the successive products are called powers of that number. So our arithmetical scale, 10, 100, 1000, &c. is com- posed of the powers of 10. In this series, however, there is a property inherent in its system of notation, namely, that the number of cyphers of the product mark the number of times that the multiplier, or root, has entered into the operation of pro- ducing it. Thus 100 is equal to 10 multiplied by 10; or, to express it algebrai- cally, 10 X 10= 100. So10 x 10 x 10 = 1000. By arule in algebra, the phi- losophy of which it is unnecessary to expound here, a number is considered the first power of itself. So 100 is the 2d power (square) of 10; 1000 the 3d power (cube); 10000 the 4th power, &c. Another notation, however, to the same effect, is to repeat the root itself with a small number beside it, indicating the order of the power, thus 10’, 10°, 10’, &c. Here is an example of the modern notation of powers and exponents. But it is only the notation in a particular case, and must be generalised before it can acquire the important place it actually holds in the system of numbers. One grand dis- tinction betwixt arithmetic and algebra is, that the former considers and works a ques- tion in reference only to a particular case, while the latter affords a general rule for a variety of cases. Hence in algebra the letters of the alphabet are taken as symbols to represent indefinite quantities. |The notation of which an example is given above may be considered as applicable to any geometrical progression of numbers, and consequently, is capable of being expressed in the general language of algebra. Thus take any number a for the root, or first power, and its successive powers will be a? a° a‘, &c. which signify the same as aa, aaa, aaaa, &c. or it may be still further generalized, a being taken for the root, and x for the exponent, thus a*: this expression is called an exponential quan- tity, where a may stand for any root, and x for any exponent; and therefore a” may re- present all possible values or numbers from zero to infinity. The universal exponential notation, of which an example is here given, belongs to a vast and fertile field of algebraic analysis, that cannot be said even to have opened in Napier’s time. Stifellius, Bombelli, Stevinus, and a few others, made some rude attempts to denote the exponents of powers by indices, or small numbers; but this notation was not immediately ap- preciated or improved, and even Harriot, whose algebra appeared long after Napier’s death, denotes the order of the power, by the defective and cumbrous expedient of repeating the root itself, thus, a, aa, aaa, &c. To the great Descartes is yielded the merit of the exponential notation now in use, and hence it is called the Cartesian 460 HISTORY OF THE notation. Through this it was that the universal arithmetic of powers and exponents became developed. The system was found to be flexible to any extent and in every direction. The law of continuity (or that algebraic principle which considers a numerical scale as indefinitely extended in both directions, ascending and descending) introduced inverse powers and negative exponents, as the reciprocals of direct powers and positive exponents,—an extension precisely similar to that which Napier first gave to the arithmetical scale, when he proposed the notation of Decimal fractions. The doctrine of fractions was also applied to exponents ; and it was discovered that integral and fractional exponents, whether rational or surds, belonged equally to the same system of notation, and could be worked in the same manner. Thus decimals came to be used as fractional exponents. In short, passing through many illustrious hands, the exponential system obtained an unlimited extension, so that in Newton’s it reached the Binomial Theorem, which may be called the bridge that spans the chasm betwixt common algebra and the higher calculus. One result of this analytical developement, even before it reached the crisis of Newton, was very important, but not so exciting as it would have been had Napier not antici- pated the treasure. It is obvious that the exponents of any root compose an arithmetical series, adapted to a geometrical one which is composed of the powers whose values the exponents express ; consequently, when it was discovered that an exponent might be a number of any denomination, integral or fractional, negative or positive, rational or surd, it followed directly that every number whatever might be considered as a power of any given number. Thus, for example, 100 is a power of 10, whose exponent is 2, 7. e. 10?= 100. Now, as the value of a power depends upon its exponent, and as the system is found to be infinitely flexible, it follows that the numbers betwixt (say) 10 and 100 could be viewed as powers of 10, having their values denoted by fractional exponents ; for, although none of these powers would be commensurable, the doctrine of surds af- forded a notation expressive of approximations infinitely near the truth. Here, then, is the adaptation of an arithmetical to a geometrical series, including numbers of every possible description, so that the logarithmic principle observable in the Arabic system is no longer confined to the ascending decuple scale, but, from a special arithmetical case, has become an algebraic law of universal application. It would have been impossible to have reached this refined extension of the notation of powers and exponents, without detecting all those operations by means of the exponents which afford the same re- sults as the more complicated operations with the corresponding powers; and by this path Napier’s great invention must have been discovered ; for the observation is perfectly just, that in whatever terms the method of Logarithms has been stated and explained, its principle may be reduced to this, “ that all numbers are feigned to be equal to the powers of a certain assumed number.” Had the Logarithms been disclosed through this gradual progress of the notation of powers and exponents, however valuable the discovery, it would probably not have at- INVENTION OF LOGARITHMS. 461 tached an immortal name to any individual. We would have been indebted for it to all those who had improved and advanced the algebraic notation in which it lurked. It would have been insensibly attained, as it were, in the natural and inevitable course of numbers, and would have been due to a system, the very dawn of which had not appeared in our philosopher's lifetime, wnless that dawn be his own work. Professor Playfair remarks particularly, that Napier could derive no assistance from such analytical considerations, but arrived at the Logarithms by an original path of his own; and for that reason he bestows this eulogy upon him, that, “as there never was any invention for which the state of knowledge had less prepared the way, there never was any where more merit fell to the share of the inventor.” Yet the real value of this praise, which is as just as it is high, has been obscured in quarters where we would have least expected confusion on the subject. Professor Powell, whose work, already referred to, is the latest history of mathematics in which Napier is mentioned, has transferred almost verbatim to his own text Playfair’s account of the Logarithms and eulogy of their author. But, overlooking the real point of that eulogy, the Savilian professor adds rather inconsistently, “‘ Hence, to conceive the fundamental idea, that all numbers might be regarded as some powers of one given number, and to devise the actual means of finding the indices of those powers, must be allowed to have been indications of genius of the highest order.” But the fun- damental idea here assumed to have been Napier’s, belongs to a subsequent developement of algebraic analysis, independently of which, for that was his great merit, he achieved the Logarithms. It is an idea belonging to that mature state of the exponential sys- tem wherein a chapter, “* De quantitatibus exponentialibus ac Logarithmis,” * is made pre- liminary to an exposition of the infinitesimal analysis. But it is at variance with the history of analytical science to suppose that Napier could generalize like Euler, which, however, he must have done if he really reached the Logarithms by the contemplation in question. Delambre, while he views the Canon Mirificus through the modern analysis, is most care- ful to avoid giving the impression that Napier did so, or had the aid such a view implies ; *‘ C’est par anticipation (says he) que j’ecris na, 77a, n°a, &c. on n’avait encore aucune idée des exposans ;” and wherever that. philosopher uses such expressions in reviewing our philosopher’s work, he reminds the reader that Napier did not look through any such medium as this translation of his thoughts might seem to imply; ‘ce calcul est /a traduction de ses rai- sonnemens.” Herschel observes, that Wallis’s Arithmetica Infinitorum, published in 1655, is the first work “in which we find that full reliance on what is called the law of continuity in analytical expressions, which has since led to so many brilliant generalizations;” but that ‘¢ the notation of exponents was invented by Descartes.” Now unquestionably the fun- damental idea attributed to Napier is only co-existent with a knowledge of the full mean- ing and utility of exponential notation ; and we would put it, therefore, to the manes of Dr Hutton, and the cathedra of Professor Powell, whether, before the close of the six- * Introductio in Analysin Infinitorum. Auctore Leonhardo Eulero, 1797, cap. 6. 462 HISTORY OF THE teenth century, Napier can be supposed to have generalized in this form av=y?* Did he select a base for his system? or consider a base in Logarithms at all? or can he be sup- posed to have known that e (a transcendental number begotten upon the Canon Mirificus by the Binomial Theorem,) + was really the base of his own original and parent system of Logarithms ? If he could know nothing of all this, then it is only confounding the his- tory of his invention to say, that the algorithm of powers led to it, or that the foundation of his conception was the analytical idea, that all numbers might be regarded as some powers of one given number. But we-verily believe, that, had Napier lived twenty years longer, he would have reaped in rapid succession many of those laurels which the path of analytical science yielded so gradually to many philosophers between him and Newton. In his letter to King James, he tells that monarch that he could bring him gifts as rare as Tycho’s. He verified that hint with the Canon of Logarithms. In his dedication of the Logarithms, he tells Prince Charles, that, if he received them in good part, it would “ encourage me, that am now almost spent with sickness, shortly to attempt other matters perhaps greater than these.” Had he been spared, this promise, too, would have been realized. There was before him the whole of that wonderful field of analytical inquiry, from which, by an- ticipation, he had already snatched one of its most precious disclosures. We must now turn to his manuscript ‘* Booke of arithmeticke and algebra,” which affords the most con- vincing proofs, that with an innate algebraic power equal to Newton’s, but without one * The equation a” = y contains various relations. «x is the exponent of a; y is the power of a; ais the root of y; x is the logarithm of y; y is the number of which z is the logarithm. Thus it is obvious that the exponent of a and the logarithm of y mean the same quantity. In this equation a is also termed the base, and so 2 is the logarithm of y to the base a. Of this algebraic generalization the algorithm 102 = 100 isa particular arithmetical case. 2 is here the exponent of the operation of raising 10 to its se- cond power, 100; 2 is therefore the logarithm of 100, and 10 is the base of that logarithm. These are modern refinements in analytical science of which Napier knew nothing. He had not the algorithm. + The letter ein modern algebra is taken to represent the base of Napier’s first system of logarithms, which is the fundamental and parent system of all logarithms. That base is equal to the number 2.7182818. Now, until the binomial theorem, and the modern doctrines connected with it, afforded new and comparatively easy methods of computing logarithms, the number e was unknown. A treatise on arithmetic and algebra, published by the Society for the Diffusion of Useful Knowledge, details the algebraic process which produces the number e, and the author adds, “ the student will find e = 2.7182818 ; this quantity then is known; the discovery of it does not at present appear to have brought us nearer our object, but we shall find it a necessary instrument in arriving at it; it is the base of a system called the Napierean, from Napier, a celebrated mathematician of the seventeenth century, who invented logarithms, and calculated them to this base.” But this is a complete mistake. Napier did not calculate his system to a base at all; it might as well be said that he computed his tables through the eapansion of a”, or by means of a a rapidly convergent series. Napier was so far in ad- vance of science that men forget when he lived. Delambre most justly observes, that the easiest me- thods of computing logarithms were discovered after the greatest difficulty and toil had been accom- plished. INVENTION OF LOGARITHMS. 463 of the many powerful aids which the English philosopher obtained from the algebra of his day, Napier, ere he found the Logarithms, had launched himself in the very path most likely to have led him even to the Binomial Theorem. This very interesting fragment has hitherto been secluded in the family charter-chest. Unfortunately it is written in Latin, and would occupy upwards of 130 quarto pages, so is not suited for an appendix to his memoirs in its original state. I shall endeavour to give such an account of it as will afford some insight into the nature of the prepara- tory study, and mental discipline, through which our philosopher passed to the com- plete accomplishment of his greatest design. ‘The reader must not fail to keep in view the circumstances of its ancient date, and the local disadvantages under which the treatise was written. We have already noticed the works upon the same subject that were published before he can be supposed to have written anything ; and, considering how few they were, how slowly books were then spread abroad, and that literary com- munication between Scotland and the Continent was then so slight, as to leave Kepler in ignorance of Napier’s death two years after that event, we must not suppose that our philosopher had at his command even those scanty sources of information the Continent could afford on the abstruse subjects to which he was attached. ‘This is not to ex- cuse defects or rudeness in his treatise on numbers, but to enhance the surprise that he should then have written as he did, and that even his unpublished papers should be so worthy to meet the eye of modern mathematicians. Any one who now takes the trouble to peruse the Canon Mirificus, and his other published works, (and this is rarely done even by men of science), will be struck, not merely with the invention, but with the power, simplicity, and elegance that characterise all his treatises, and the air that pervades them of having been written a century after his time. ‘The very same may be said of the manuscript we are about to consider. Whole chapters of it might be literally translated and transferred to the most careful and recondite treatise on numbers of the present day. Yet it is the oldest treatise of the kind composed in Britain. Recorde’s works are rudely elementary compared to this of Napier’s, which is a beautiful treatise on the philosophy of numbers, free not merely from the puerile facetie * of the old English writer, but, what is remarkable, from every vestige of mysticism or superstition. It must have been composed before he had formed an idea of the Logarithms, because al- though the arithmetical part is entire, and brought to a close, there is not the slightest allu- sion to his great invention, nor to the system of Decimal fractions. I presume, therefore, * “ Master. Exclude number, and answer this question; how many years old are you? Scholar. Mum.— Master. How many days in a week ? how many weeks ina year ? what lands hath your father ? Scholar. Mum.—Master. So that if number want, you answer all by mummes. How many miles to London? Scholar. A poak full of plums.—Master. If number be lacking it maketh men dumb, so that to most questions they must answer mum,” &c. “ What call you the science you desire so greatly ? Scholar. Some call it arsemetrich, and some augrime.—Master. Both names are corruptly written, arsemetrick for arithmetic, as the Greeks call it, and augrime for algorisme, as the Arabians sound it,” &c.— Recorde’s Arithmetick, 464 HISTORY OF THE it was written before he had seen the work of Stevinus, which he quotes in the Rabdo- logia. Unquestionably it is the oldest philosophical treatise on numbers composed in Scotland. The general plan and division of his subject is of itself sufficient to show the profound and comprehensive view he had taken of numerical science. He terms his subject, gene- rally, Loaistic (logistica, ) which he defines “ the art of computing well,” and his princi- pal division of it is into four books, of which the first (he says) regards the computation of quantities common to every species of logistic; the second relates to Arithmetic, which he defines, “ the Logistic of discrete quantities by discrete numbers ;” the third, he calls Geometrical Logistic, and defines it ** the Logistic of concrete quantities, by concrete numbers ;” the fourth is Algebra, which he defines, “ the science of solving questions of magnitude and multitude” (quanti et quoti.) 'The classification of his system, minute. clear, and philosophical, affords a striking ulustration of what Robert Napier declared to be the acknowledged characteristics of his father’s mind, namely, the power with which he could condense, and the simplicity with which he could expound. The first book con- sists of eight chapters, and commences in this simple manner. “ Logistic is the art of computing well. Computation is the action or operation which, from several given quantities and their properties, finds what is sought. These are given either by vocal nomination, or in written notation. Hence in all Logistic, first comes nomination and notation, and then follows computation. Computation is either simple or compound. ‘That is simple computation which, from two given quantities, finds a third by a single or uniform operation. Simple computation is either primative or derivative. That is primative computation which computes one quantity with another only once; and which, from any two of a whole, a part and a remainder given, finds the third. Primative computation is either Addition or Subtraction. Addition is that primative com- putation in which several quantities are added, and a whole is produced: ez. gr. let 8 and 4 be added, and there will be produced 7 for the whole: so let 2, 3, and 4 be added, and there will be produced 9. Subtraction is that primative computation in which the subtrahend is taken from the minuend, (subtrahendum a minuendo,) and a remainder is produced. Thus, let 4 be taken from 9, and 5 remains. 4 is called the subtrahend, 9 the minuend, and 5 the remainder. Subtraction is either of equal quantities and no- thing remains, or of wnequal quantities. The subtraction of unequal quantities, is either of the dess from the greater, and the remainder is a quantity greater than nothing (major nihilo,) or it is of the greater quantity from the less, and the remainder will be less than- nothing (minus nihilo). ‘Thus, subtract 5 from 5, and there remains nothing : subtract 3 from 5 and there remains 2 more than nothing: but subtract 7 from 5 and there re- mains 2 less than nothing, or nothing diminished by 2. Hence the origin of defective quantities, namely, by the subtraction of the greater from the less, and of these I shall speak in their proper place. From the premises, it is clear that Addition and Subtraction are related ; and thus the one is the proof ee of the other. Thus, as a proof whether INVENTION OF LOGARITHMS. 465 2 is the remainder of 3 from 5, add 2 and 3, and 5 is restored. On the other hand, as a proof whether 2 and 3 added make 5, subtract 3 from 5 and 2 is restored; or other- wise subtract 2 from 5 and 3 is restored. There is, besides, another proof of subtraction in itself, namely, by subtracting the remainder from the minuend, so as turn the first subtrahend into the remainder ; thus, as the proof whether 2 be the remainder of 3 from 5, subtract 2 from 5 and 3 is restored. And so it is, that any two of a whole, a part, and a remainder being given, you have the third by Addition and Subtraction.” Having disposed of his general view of primative computation in this first chapter, Na- pier passes in the second to derivative (orte,) which he defines, “ the computation of quan- tity with quantity more than once.” He considers it as derived either from Addition and Subtraction, by a repetition of those primative operations (orte ex primis,) which gives Multiplication and Division ( Partitio ;) or as derived from these again (orte ex primo ortis,) which gives radical-Multiplication and radical-Partition ; in other words, involution and evolution. Nothing can be more elegant and symmetrical than the manner in which he brings out the genealogy of those great operations whose prolific field was all before him. We have seen, in the first chapter, that his leading division is into simple and compound com- putation. He regards all simple computation as having to do with three quantities, of which any two are given, and the third is to be found from them ; and he also shows how intimate- ly all simple computations are related to each other ; the different species of the same kind being the mutual proofs of each other, and the different kinds naturally arising each out of the more primative. He shows how Addition and Subtraction test each other. Mul- tiplication he views as continued Addition, and defines it thus elegantly ; ‘¢ Multiplication is the continued addition of either of the two given quantities, as often as there are units in the other; the product is the multiple ; thus 3 multiplied by 5 is the same as 3 five times added, or 5 three times added; being 15.” ‘The three quantities in this operation he calls the multiplier, the multiplicand, and the multiple. Division he views as “ the continued subtraction of the partient from the partitor until nothing remain, and the number of sub- tractions is the quotient.” He then shows that Division may be perfect or imperfect, and points out how “ fractions derive their origin both from the partition of the less by the greater, and the cmperfect partition of the greater by the less;” and he concludes, as in the previous chapter, by showing that Multiplication and perfect Division mutually prove each other. The third chapter contains the third class of simple computation, namely, that which is derived from Multiplication and Division by a repetition of those operations. Here the three quantities considered are thus defined; “ the radicate * is that quantity * What Napier calls radicatum is now called power. It forms another of the several coincidences between Napier and Sir Isaac Newton, that the latter also wrote a Latin work upon arithmetic and algebra, entitled Arithmetica Universalis, being the substance of his lectures delivered at Cambridge. In that work I find Newton, like Napier, uses the words index and radix ; but the third quantity he calls“ dimensio, vel potestas, vel dignitas.” Napier’s radicatum will bear the most hypercritical scrutiny ; it regards the quantity as rooted, or composed of roots, which are to be decomposed, or evolved, in 3N 466 HISTORY OF THE which returns to unit by repeated partition by some other quantity; the number of par- titions is the index, the dividing number is the root.” ‘These three quantities he consi- ders subject to three operations; 1. radical-Multiplication, which he defines, the conti- nued multiplication of the given root, as often as there are units in the index, to produce the radicate sought;” and he shows that the remultiplication may be infinite; it may be “ duplication, which is the multiplication of two equal quantities together, or the given quantity placed twice, (bis posite); triplication is the given quantity thrice placed, &c. in these cases the radicate becomes the duplicate, or triplicate, or quadruplicate, &e. the index is two, or three, or four, &c. the root is bipartient, or tripartient, or quadripartient,” &c. The example he affords is by placing 2 for the root, and 2 for the index, and then he raises 2 to the seventh power, as ‘in the following table, where the prior series (prior series) are indices, and the latter radicates, BSN MT Pe eT TO ETT POL TET ey ae rea ee se oc 1nd Quince BO coi i ABy lA ees tawil 6 Ui 82 De Aah tobe es Meme ct He next considers, (in the same chapter) 2. radical-Partition, which he defines, “ the continued partition of the radicate by the root down to unit, and the number of par- titions is the index sought. In the fourth chapter, he takes up the important case of, 3. Extracting the root itself. He defines this process, “ finding that third quantity which, the index being given, raises the given radicate by radical-Multiplication, or resolves it by radical-Partition.” He then lays down that the extraction may be perfect or imper- fect; “ perfect where there is no remainder,—imperfect where a remainder is left irre- soluble ; thus, if the ¢ripartient-root is to be extracted from the radicate 9, the nearest number is 2, which by radical-Multiplication raises 8, and not 9; it is, therefore, called an imperfect extraction, as 1 remains unextracted ; whatever numbers so remain are termed irresoluble (crresolubiles ;) the number obtained by the imperfect extraction is called the lesser term, to which, by adding unit, the greater term is obtained ; between which terms the true and perfect root lies hid.” Our philosopher then proposes a very order to produce the indez, which again denotes the quality of the radiz. Radicatum being thus ex- pressive, I have translated it radicate instead of power. * It is curious to find, in this example, the inventor of Logarithms framing a logarithmic table un- conscious of that property of the particular arrangement. The reader will at once perceive the Archi- medean theorem in the numeral arrangement quoted ; the upper series being truly logarithms to the lower. But Napier gives it without any reference to that particular property. Had this been his first step to the Canon Mirificus, that work would have presented a very different aspect. We would pro- bably have heard nothing of his fluzions and fluents ; but every thing about the arithmetic of indices ; he would have selected a base for his system, and that a simple one; the tables computed under those circumstances would probably have been of the kind called antilogarithms. (See Dr Hutton’s His- tory of the Construction of Logarithms, and Dodson’s Preface.) The example shows that Napier had not the exponential system in a state to reach the logarithms by that path, though he unconsciously affords a rude table of powers and exponents as well as of logarithms; had he simply repeated the root instead of giving the radicate, and then reduced his indices to small numerals thus, 21, 22, 23, 24, 25, 26, 27, he would also have afforded a specimen of the Cartesian notation. INVENTION OF LOGARITHMS. 467 curious notation of his own for these imperfect roots, which shall be afterwards noticed more particularly. His next proposition is, that ‘in radical-computations, some indices are even and some odd ; some again are prime, i.e. only divisible by unit, others compo- site, i.e. perfectly divisible by some other number.” After giving examples, he adds, ** hence a compendious method of radical- Multiplication and Extraction where the indices are composite, for it is easier to multiply, or extract, by means of the component parts of the index separately, than by the composites themselves,” &c. He closes this chapter, as the former ones, by showing that each of the three operations of radical computation is proved by the other two. ‘This concludes his general view of simple computations, — their relations to and dependencies upon each other. I may here observe that he never leaves a term without a definition, or a proposition without examples. The remaining four chapters of the first book are devoted to the general view of “© compound computation, or ules.” ‘This he defines “ the computation which, by several and divers modes:of operation, produces the quantity sought from several given quanti- ties.” The fifth chapter accordingly treats of compound computation, embracing rules of proportion and disproportion. It contains a remarkable example of his practical powers, and of his unremitting attempts to create compendious rules where he found them want- ing. I shall translate it, therefore, nearly at length, as he seems to have laid some stress upon his own peculiar method ; and it may be doubted if any thing better is to be met with on the subject even now. ‘¢ Rules of Proportion are those which solely by means of simple proportionate com- putations, such as Multiplication and Partition, discover from several given quantities the quantity sought; as, if it be asked, how many miles he may go in 6 hours who goes 4 miles in 3 hours? or,—if 6 oxen be nourished for 4 days upon 3 measures of hay, how many oxen may be nourished in 2 days upon 5 measures? or,—20 shillings Scotch are 1 pound, 2 pounds are 3 marks, 5 marks are worth 1 crown ; how many shillings, then, are 9 crowns worth? Questions of proportion have no introduction through Addition and Subtraction; for Multiplication and Partition are proportional computations as a con- sequence of their definitions. Two things are considered in such computations,—posi- tion, and working. Position is regulated by four precepts. “rst, that a line be drawn, and a place prepared under it for the quantity sought, along with its collaterals, as fol- lows, in terms of the three examples given above. 6 hours, 4 miles. 6 oxen 5 meas. 4 days. . 20 shil. 2 pnd. 5 mr. 9 er. * 3 hours, how many miles. “" how many ox. 3 meas. 2 days. ~~ how many shil. | pnd. 3 mr. | er. Second, that two quantities, of which the one decreases as the other increases, be placed as collaterals on the same side of the line. As, in the first example, by how much the first hours abound, namely, 3, so much fewer will be the miles sought; in the second example, as the number of oxen increase, the number of days in which they may be nou- rished on the same measure decrease; hence, 3 hours and the miles sought,—6 hours and 4 miles,—again, 6 oxen and 4 days,—the oxen sought and 2 days,—are respectively 468 HISTORY OF THE placed on the same side of their lines. Third, that two quantities increasing or decreas- ing together, must be placed on the opposite sides of the line; thus, as the 3 hours in- crease, so must the 4 miles, e¢ contra,” &c. “ Fourth, that two cognominate quantities be always separated by the line; as in the first example, 3 hours to 6 hours, and 4 miles to the miles sought,” &c. “ These precepts of position being attended to, the following single general precept of working will suffice for the solution of every question of this kind.”— “© Multiply the upper quantities together, also the lower together ; then divide the multiple of the upper quantities by the multiple of the lower ; and the quotient will solve the question by giving the quantity sought. ‘Thus, in the first example, 6 and 4 multiplied make 24, which divide by 3, and that will give 8, the number of miles sought ;—or, in the second ex- ample, 6, 5, and 4 multiplied make 120, then multiply 3 and 2, which make 6, by which divide 120, and that will give 20 and solve the second question ;—or, in the third ques- tion, multiply 20, 2, 5, and 9 together, which make 1800; then multiply 1, 3, and 1, which make 3, by which divide 1800, and that will give 600, the number of shillings which are equal in value to nine crowns. In this manner, J bring every species of rules of proportion under one general method and operation. ‘The authors treat of infinite species and forms of the doctrine of proportion, such as the rules of three or the golden, of simple, double, five-quantities, six-quantities, direct, inverse, &c. but they have not touched the triple rule, or any of its manifold forms, all of which you have here in this brief form.””* ‘¢ So much for Rules of Proportion ; the Rules of Disproportion follow ; but as these, besides the proportional computations, embrace additions and subtractions and other computations disturbing proportion, mixed up together, therefore I dismiss all these, as what may be sufficiently comprehended under algebra. As the rules of alligation, society, falsehood, simple proportion, double proportion, and many others, form the greatest part of all arithmetical rules, so of geometrical rules do propositions, problems, theorems, &c. which, confused both from their variety and number, disturb the memory. These therefore I Jeave, to be presently treated of under algebra.” Having disposed of quantities ‘ im genere,” Napier takes up the division “ suarwm spe- cierum.” His first division of the species is into abundant and defective quantities, (abun- dantes et defective, ) to which the sixth chapter is devoted. Upon this chapter our phi- losopher lays much stress, and I shall give it entire. «¢ Abundant quantities are those which are greater than nothing (majores nihilo, ) and carry the idea of increase along with them. ‘These have either no symbol prefixed, or this one +, which is the copulative (copula) of increase. Thus, if you are not in debt, and your wealth be estimated at 100 crowns, these may either be noted 100 crowns, or * Recorde’s Arithmetic confirms this remark. There I find, the golden rule direct and inverse, the double rule of proportion, the rule of proportion composed of five numbers, the rule of fellowship, the rule of alligation, the rule of falsehood ; but nothing similar to Napier’s. He made every rule golden that he touched ; witness his trigonometrical rules. 3 INVENTION OF LOGARITHMS. 469 ‘+ 100 crowns; and are read a hundred crowns of increase ; always signifying wealth and gain. ‘The computations of such quantities are to be learnt both from what has been said and what is to follow. Defective quantities are those which are less than nothing (minores nihilo, ) and carry the idea of diminution along with them. ‘These are always preceded by this symbol —, which is the copulative of diminution. Thus, in the estima- tion of his wealth whose debts exceed his goods by 100 crowns, justly his funds are thus prenoted, — 100 crowns, and are read, a hundred crowns of decrease ; signifying always loss and defect.* I have already shown that defective quantities have their origin in * Abundant and defective terms are now used in a totally different sense.’ A number is some- times considered as composed of aliquot parts, 7. e. of other numbers, any one of which, being repeated a certain number of times, makes up the whole number precisely ; thus 1, 2, and 3, are the aliquot parts of 6. Now when the aliquot parts of a number, added together, make up a sum greater than that num- ber, they are the aliquot parts of an abundant number ; if less, of a defective number ; if precisely the number, as in the example given, it is a perfect number. The terms now in use to express Napier’s idea are negative and positive. Sir Isaac Newton, in his Algebra, says, “ Quantitates vel affirmative sunt, seu majores nihilo ; vel negative sewnihilo minores. Sic in rebus humanis possessiones dici pos- sunt bona affirmativa, debita vero bona negativa ;” the very example which Napier gives. Dr Horsley, Newton’s commentator, observes at this passage; “ Albertus Girardus, ni fallor, omnium primus, (quem summum interea mathematicum agnosco,) dura quddam verborum figura, Diophanto et Viete prorsus ignotd, quam vellem Cartesius et nostrates minus avide arripuissent, nihilo minores, dizit.” This shows how neglected Napier’s great work is by the learned. Horsley, of course, could not know, that in Napier’s unpublished manuscript there was a chapter upon this distinction, but he might have read in the Canon Mirificus, c.i. p. 5, “ Logarithmos sinuum, qui semper majores nihilo sunt, abun- dantes vocamus, et hoe signo +, aut nullo prenotamus ; logarithmos autem minores nihilo defectivos vocamus, prenotantes eis hoc signum —.’ This was published fifteen years before the work of Girard, to which Horsley alludes. Dr Hutton, in his History of Algebra, has fallen into the same mistake ; “ Girard was the first who gave the whimsical name of quantities less than nothing to the negative ones.” Here is another indication that Hutton analyzed Napier’s works, and presumed to attack his character, without reading the original proofs as he ought to have done. Even Leslie and Playfair had not read the Canon Mirificus. The former says, “ Girard was possessed of fancy as well as in- vention; and his fondness for philological speculation led him to frame new terms, and to adopt cer- tain modes of expression which are not always strictly logical ; though he stated well the contrast of the signs plus and minus, in reference to mere geometrical position, he first introduced the very inac- curate phrases of greater and less than nothing.” Playfair says, “ Girard is the author of the figurative expression, which gives the negative quantities the name of quantities less than nothing ; a phrase that has been severely censured by those who forget that there are correct ideas which correct language can hardly be made to express.” It is, indeed, wnphilosophical fastidiousness to call the phrase “ very inaccurate.” Napier fortified it by a better nomenclature, in the terms abundant and defective, than those now in use,—positive and negative, which are said to convey erroneous impressions. Again, his exemplification of the idea is that which is invariably adopted now, though not from him. Surely Euler was never rummaging in the Merchiston charter-chest ? Yet his illustration is identically Na- pier’s ; “ In algebra, simple quantities are numbers considered with regard to the signs which precede or affect them. Farther, we call those positive quantities, before which the sign + is found; and those are called negative quantities which are affected by the sign —. The manner in which we ge- nerally calculate a person’s property is an apt illustration of what has just been said; for we denote what 470 HISTORY OF THE subtracting the greater from the less. Abundant and defective quantities come under the operation of Addition; where the signs are alike, by prefixing their common sign to their ageregate sum 5 thus, + Sand + 2 make + 5; but if their signs are unlike, they are added by prefixing the sign of the greater quantity to the difference between them; thus, + 6 and—4make +2. In Subtraction they are worked by changing the sign of the subtrahend, and adding it to one or other of the given quantities according to the foregoing rules ; thus, in subtracting -+- 5 from + 8, change + 5 to — 5, then, as before, add — 5 to + 8, which gives + 3, the remainder sought; so to subtract + 8 from — 5, change + 8 into — 8, which added to — 5 gives — 13, the remainder sought; so — 5 from + 8 gives + 13; and + 5 from — 8 gives — 13; and — 5 from — 8 gives — 3; and + 8 from + 5 gives — 3; and — 8 from + 5 gives + 13; and — 8 from — 5 gives + 3. Abundant and defective quantities are multiplied and divided, where the signs are alike, by prefixing to the mul- tiple or the quotient the sign of plus, (pluris ;) or, if unlike, the sign of minus, (minutionis:) thus, + 3 multiplied by + 2, or — 3 multiplied by — 2 produce the multiple + 6; and if + 6 be divided by + 3; or — 6 by — 8, the quotient + 2 is produced. But if + 8 be multiplied by — 2, or — 3 by + 2, the multiple will be —6; and if + 6 be di- vided by — 3, or — 6 by + 3, the quotient will be — 2.” ‘¢ Roots, both abundant and defective, having an even index, when radically multiplied produce an abundant vadicate ; thus, multiply the root +. 2 to the index 4, and there will be given, first, -+ 2; second, + 4; third, + 8; fourth, + 16; in like manner — 2 gives, first, — 23 second, + 4; third, — 8; fourth, +- 16, as before. Hence it follows, that an abundant radicate, whose index is even, has two roots, one abundant, and the other defec- tive, and that a defective radicate has no root ; for in the above example both the abundant + 2, and the defective — 2, are the quadripartient (fourth) roots of the abundant radicate +. 16; therefore there are none remaining, either abundant or defective, which can be the a man really possesses, by positive numbers, using or understanding the sign + ; whereas his debts are re- presented by negative numbers, or by using the sign —: Thus, when itis said of any one that he has 100 crowns, but owes 50, this means that his real possession amounts to 100— 50; or, which is the same thing, + 100—50,i.e.50. Since negative numbers may be considered as debts, because positive numbers repre- sent real possessions, we may say that negative numbers are less than nothing ; thus, when a man has no- thing of his own, and owes 50 crowns, it is certain that he has 50 crowns less than nothing ; for if any one were to make him a present of 50 crowns to pay his debts, he would still be only at the point of no- thing, though really richer than before. In the same manner, therefore, as positive numbers are incon- testably greater than nothing, negative numbers are less than nothing.” Maclaurin, too, defends the phrase, but illustrates the idea more poetically; “ the depression of a star below the horizon may be equal to the elevation of a star above it ; but those positions are opposite, and the distance of the stars is greater than if one of them was at the horizon so as to have no elevation above it, or depression below it; it is on account of this contrariety that a negative quantity is said to be less than nothing ; because it is opposite to the positive, and diminishes it when joined to it, whereas the addition of 0 has no effect ; put a negative is to be considered no less as a real quantity than the positive.” The opinion of Leslie, who calls the phrase inaccurate, and of Hutton, who calls it whimsical, must go down before the opi- nions of Napier, Newton, Maclaurin, Euler, and Playfair. INVENTION OF LOGARITHMS. 471 quadripartient root of the defective radicate — 16. Abundant roots, having wneven indices, when radically multiplied yield abundant radicates; and defective roots, defective radicates ; thus, the abundant root + 2, when radically multiplied to the uneven index 5, yields + 32; namely, first, + 2; second, + 4; third, +- 8; fourth, + 16; fifth, +- 32, the abundant radi- cate; so the defective root — 2, with the index 5 radically multiplied, yields — 32, name- ly, first, — 2; second, + 4; third, — 8; fourth, + 16; fifth, — 32, the defective radicate of the said root. In like manner hence it follows that a radicate with an uneven index has only one root, an abundant radicate an abundant root, and a defective radicate a de- fective root; as in the former example, the abundant radicate + 32 with the index 5, will have the abundant root + 2; so the defective radicate — 32, with the same index, will have the defective radicate — 2. It is unnecessary to repeat here the rules of propor- tion, as they are compounded of multiplications and partitions, and may be learned from what is premised.” In a subsequent part of his manuscript, when treating of the notation of irrational roots, we shall find Napier referring to this chapter as the foundation of a great algebraical secret, not previously revealed by anyone. ‘This shall be considered more particularly, when we come to notice the chapter where these expressions occur. It must be observed, however, that he here lays down the general rules of the arithmetic of plus and minus, and connects the chapter with his system, in a manner not sur ppageds if equalled, in the treatises of Newton, Maclaurin, and Euler. Our philosopher, i in the next place, passes to his second special division of quantities, namely, into integral and fractional. ‘ Those quantities,” says he in chapter seventh, “are called integral, which have no denominator, or whose denomimator is unit; and those fractional, whose denominators are varipus. ‘The denominator is the quan- tity placed under the line, and indicates the number of parts into which unity is di- vided; the uumerator is the quantity placed above the line, and denotes how many of those parts are taken. For instance, this quantity 3ad is an integral quantity; so is a which is the same thing written in the form of a fraction; again, oe and i nd 2 or 3, which is the same thing, are fractions or broken quantities, whose higher farina the numerators, and whose lower terms are the denominators.” Our philosopher then re- minds his reader that it had been previously observed how broken quantities are also pro- duced greater than unit, namely, by the imperfect division of the greater quantity by the less. ‘* Thus, 9 divided by 2 yields 44, or, if you prefer it, 3 greater than unit. Hence every numerator sustains the part of the quantity divided ; an its denominator, of the ghee that divides it; as in the former example, = signifies that 3ad is divided by 2dc; so 5- has the same value as 3a divided by 2a; or, more briefly, 3 divided by 2; or, fi- vies it has the same value as three parts of unity divided into 2; so ? are three-fourths of unity, or three divided by four, which is the same thing.* Every quantity having a * Evuter might have written all this; indeed he has written something very like it; he traces from the same source as Napier does the “ particular species of numbers called fractions, or broken numbers ;” 472 HISTORY OF THE numerator and denominator is considered and worked as a fraction, and hence, in order to compute with integers as if they were fractions, 1 is placed beneath them as their deno- minator. The computation with fractions is facilitated by contracting and abbreviating their terms (termini). This is done by dividing the terms in their increased form by their greatest common divisor.* The greatest common divisor is that than which a greater cannot be found capable of perfectly dividing each term ; and it is found, first by dividing the greater term by the less; then by always dividing the preceding divisor by its remainder until nothing remain; that last divisor, the quotients being neglected, is the greatest common divisor sought; thus, the greatest common divisor of the terms 55 and 15 is found in this manner: divide 55 by 15, there remain 10; divide 15 by 10, there remain 5; divide 10 by 5, and nothing is left over ; 5, therefore, is the greatest common divisor, measuring 15 by 3, and 55 by 11. If, however, you arrive at unit for the di- visor, then the terms are inabbreviable, and prime, or prime to one another; thus, let the terms be 5a and 3a, divide 5a by 3a, and there remain 2a; then divide 3a by 2a and la remains, by which divide 2a and there is no remainder. Hence 5a and 3a have not a greater divisor than unity, or la, by which if those terms be divided, they become to each other the prime numbers 5 and 3, as more fully shall be laid down in its proper place. But this must be specially looked to in the partition of incommensurable quan- tities that it will go on eternally without end, as will plainly appear in its proper place ; thus of the number 10 and its dipartient root, or, as 2 is called, square root, no common measure will be found in eternity ; much less that greatest divisor ; as in its proper place. he explains the example Z, and then says, “ so, in general, when the number a is to be divided by the number 4, we represent the quotient by + and call this form of expression a fraction; we cannot, therefore, give a better idea of a fraction > than by saying that it expresses the quotient resulting from the division of the upper number by the lower ; we must remember also that in all fractions the lower number is called the denominator, and that above the line the numerator.’ He turns and views his subject precisely as Napier does; “ the nature of fractions is frequently considered in another way, which may throw additional light on the subject. If, for example, we consider the fraction 3, it is evident, that it is three times greater than 1. Now, this fraction } means, that if we divide 1 into 4 equal parts, this will be the value of one of those parts ; it is obvious, then, that by taking 3 of those parts, we shall have the value of the fraction 3.”—Hewlett’s translation of Euler’s Algebra, 1822. * © In order to reduce a given fraction to its least terms, it is required to find a number by which both the numerator and denominator may be divided. Such a number is called a common divisor ; and as long as we can find a common divisor to the numerator and the denominator, it is certain that the fraction may be reduced to a lower form; but, on the contrary, when we see that, except no unity, other common divisor can be found, this shows that the fraction is already in its simplest form.” This property of fractions preserving an invariable value, whether we divide or multiply the numerator and denominator by the same number, is of the greatest importance, and is the principal foundation of the doctrine of fractions. For example we can seldom add together two fractions, or subtract the one from the other before we have by means of this property reduced them to other forms.”—“ All whole numbers may also be represented by fractions ; for example 6 is the same as & because 6 divided by 1 makes 6,” &c,—Euler’s Algebra. INVENTION OF LOGARITHMS. AT3 Having obtained the greatest common divisor, and divided by it each term, the new terms arise; and this operation is termed abbreviation.” ~ We now come to the eighth and last chapter of Napier’s first book, and he treats his sub- ject so very like Euler, that we are almost surprised to find him at the addition and subtrac- tion of fractions in his eighth chapter, when Euler is only at the same subject in his ninth. But then we must always recollect what his son said of our philosopher, ex optimorum hominum sententia, inter alia preclara hoc eximii eminibat, res difficillimas methodo certé et facili, quam paucissimis expedire. “* Fractions,” says he, “ of the same denomination are subject to the operations of addition and subtraction. If their denominators are diverse they may be reduced to the same. ‘This is done by dividing each denominator by the greatest common divisor, the quotients being noted, then by multiplying both the terms of the first into the quotient of the latter denominator, you have the first new fraction ; * and multiplying both terms of the latter by the quotient of the former denominator, gives the latter new fraction of the same denomination: thus, to reduce the fractions % and 7 to the same denomination; of denominators 3 and 9, the greatest common divisor is 8, by which divide them and you have 1 for the first, and 3 for the latter; then multiply each term of 2 by the last quotient 3, and § is produced as the first new fraction; in like manner multiplying 3 by unit, which is the first quotient, gives the fraction 5 of the same denomination as §. Being so reduced, these fractions are added or subtracted by adding or subtracting the numerators ; the sum, or remainder, being taken as numerator, and the common denominator retained,” &c. In the same minute and lucid manner, and always preserving the perfect symmetry of his arrangement, our philosopher proceeds to lay down rules for multiplication, partition, extraction of roots, radical multiplication, and ra- dical partition of fractions. This closes the first book, being his exposition of the prin- ciples and rules “ common to every species of logistic.” It is particularly striking to observe that his manner of treating the subject is not sur- passed, if equalled, in modern times. With few resources beyond his own mind, liv- ing ina rude age, and in a country whose barbarian darkness in science he was the first to break, Napier surveys the vast field of computation, and not only reduces its complicated elements to a lucid order far before his times, but displays in the task * We must here observe, that Napier at once gives the most simple and perfect method of adding and subtracting fractions, and that Euler, although he indicates his knowledge of the rule, only details more imperfect ones. It is a striking fact, of which any one may easily satisfy himself, that this per- fect rule of Napier’s is not taught in the elementary books. A note to Euler’s algebra says, “ the rule for reducing fractions to a common denominator may be concisely expressed thus: Multiply each nu- merator into every denominator except its own, for a new numerator, and all the denominators toge- ther for the common denominator.” This is also the rule’ Maclaurin gives. Now it happens to be the worst rule, and Napier’s is the best. Napier’s exposition of fractions, throughout all his manuscript, is perfect. 30 A74 HISTORY OF THE a philosophical power, and a grasp of mind superior to that of Euter.* That phi- losopher’s Elements of Algebra, written in the eighteenth century, are perhaps the severest test we could adopt of the excellence of Napier’s unpublished fragments of the sixteenth century. ‘There is, indeed, a remarkable similarity between the treatises, and it is manifest that the illustrious German viewed his subject nearly with the same mental eye that Napier did. Still his treatise is less methodically arranged, less sym- metrical, less classic than Napier’s, the characteristics of which may be expressed in the words (written so lately as 1830) of Sir John Leslie; “ Nothing is more wanted for the purpose of education than a classical treatise on algebra, which, avoiding all vague terms and hasty analogies, should unfold the principles with simplicity and rigid accu- racy, and follow the train of induction with close and philosophical cireumspection.” Our philosopher’s exposition fulfils this rule in every particular, and many of his sentences are actually to be found in our most distinguished modern treatises on algebra, as if they had been translated from him. For instance, in the English translation of Euler, I find it said, “ this rule for the division of fractions is often expressed in a manner that is more easily remembered, as follows: invert the terms of the divisor, so that the denominator may be in the place of the numerator, and the latter be written under the line; then multiply the fraction, which is the dividend, by this inverted fraction, and the product will be the quotient sought: thus, # divided by 4 is the same as 3 multiplied by ¢, which makes {, or 13.” ‘Turning to Napier, to see how he treat- ed this rule two centuries earlier, I find the very same; “ partiuntur autem (fracte ) invertendo terminos divisoris, et inversos per partiendum multiplicando omnimode ut supe- rius in multiplicatione: ut sint 5 partiende per 2, hujus divisoris inverte terminos, et fient 4, que per ~, multiplicate fient primo per abbreviationem 1; +, deinde 3 2, deinde per multiplicationem superiorum invicem, et inferiorem invicem fient 2 quotus optatus, et superiores multiplicationis examen.” Again, Maclaurin’s+ expressions, “ when unit is the greatest common measure of the numbers and quantities, then the fraction is al- * “ The algebra of Euler is in various respects a most remarkable production. That illustrious ana- lyst, when. totally deprived of sight in his advanced age, dictated it in the German language to a young domestic whom he trained for an amanuensis. He was obliged, therefore, to be plain, distinct, and per- spicuous; and these qualities he combined with richness of invention.” —Leslie. Euler seems to have resembled Napier in his moral character also. “ Sweetness of disposition, moderation in his passions, simplicity of manners, were his leading features. Nor did the equability and calmness of his temper indicate a defect of energy, but the serenity of a soul that overlooked the frivolous provocation, the petulent caprices, and jarring humours of ordinary mortals. Possessing a mind of such wonderful comprehension, and dispositions so admirably formed to virtue and to happiness, Euler found no difficulty in being a Christian. Accordingly his faith was unfeigned, and his love was that of a pure and undefiled heart.’—Account of Euler prefixed to the Translation of his Algebra. + “ In our own language, Maclaurin’s Elements of. Algebra, though a posthumous work, is perhaps the ablest on the whole, and the most complete.’ — Leslie. INVENTION OF LOGARITHMS. ATS ready in its lowest terms; and numbers whose greatest common measure is unit are said to be prime to one another,” might stand as a translation of Napier’s, “ verum si ad unitatem partitorem perveneris, inabbreviables, discreti tamen sunt termini, aut se in- vicem habentes ut discreti.” Again, the author of the article Arithmetic in the latest edition of the Encyclopedia Britannica, observes, after going through the rules of the multiplication of fractions, “‘ hence we infer that fractions of fractions, or compound fractions, such as 7 of 3, are reduced to simple ones by multiplication; the same me- thod is followed when the compound fraction is expressed in three parts or more.” Napier, after gomg through the rules of the multiplication of fractions, in like manner adds, ‘* hac multiplicatione fractiones fractionum, imo et fractiones fractionum iterum atque iterum fractarum, ad simplices fractiones reducuntur : ut due quinte trium quartarum sic notate 2 ex % per premissam fiant primo § 3 per abbreviationem,”’ &c. Sir John Leslie, in explaining Lord Brounker’s fractions, observes, ‘ when the original fraction is ex- pressed by rational numbers, its decomposition must always terminate ; but, if the nu- merator and denominator be mutually incommensurable, the process of evolving their elements will never draw to a conclusion.” Napier notices the property in these words, “ verum hic summopere cavendum est a partitione incommensurabilium quantitatum, cujus nullus in eternum erit finis, ut suo loco perspicuum evadet.” Maclaurin gives the rule to reduce an improper fraction to a mixed quantity thus: “ Divide the numerator of the fraction by the denominator, and the quotient shall give the integral part; the re- mainder set over the denominator shall be the fractional part.” Napier gives it thus: “< fit autem restitutio hec partiendo numeratorem per denominatorem, et emerget in quo- tiente integra quantitas, et relinquie erunt numerator, et divisor erit denominator frac tionis ille mixte et adjuncte.” In short, it appears that our philosopher, before he, or any one else, had conceived the system of Decimal fractions, so thoroughly command- ed the difficult doctrine of vulgar fractions, that his exposition of them may be placed side by side with the best treatises on the subject now. Profoundly consci- ous of the unlimitable play of numbers, his mind penetrated the unexplored field of the Arabic system in every direction. His first, and leading idea throughout, is to show how the prominent operations upon quantity and number, gradually unfold; and how the vast fabric produces itself, growth after growth, every rule the parent of ano- ther, and the whole intimately related in all its parts, as one endless family of num- bers. This is peculiarly interesting from the person for whom the immortality was yet in store to compress with such effect that very expansion. He shows how Multipli- cation and Division rise out of the parent operations Addition and Subtraction, and how the involving of radicates, and the evolving of roots, rise in their turn out of Multiplication and Division. He afterwards, by his invention of Logarithms, pro- vided the means of obtaining all the third quantities, hitherto sought in the compli- cated rules, from the more simple operations of their respective primatives. He ex- plored the prolific system in all its channels, and then condensed it to a greater power. 476 HISTORY OF THE Having given the genealogy of numbers, in the next place with what genius he seizés unit, breaks it into a new and infinite scale, and reduces to order and beauty all the great operations of arithmetic upon its fractions. ‘The subsequent computation of his Logarithms, however, brought out a new system of fractions in Decimals. No sooner had he found these, than he at once took the view that now prevails; he regarded the great Arabic scale as acting reciprocally, in opposite directions, from right to left, and from left to right; and, rejecting in this case the notation of broken numbers, he pro- posed the point to distinguish the reciprocal play of the decuple progression. But the treatise we are considering shows that his mind had been long previously matured for such fearless and prolific views of computation. His arithmetic of plus and minus is a most in- teresting chapter, and full of genius. Before viewing an infinite scale in the fragments of unit, he takes zero, and considers that unpromising symbol as the focus of a reciprocal scale of integers extending infinitely above and below the thus dignified cypher. Destined to accomplish the Logarithms out of their natural course of discovery, he dared to conceive a scale below nothing, and to say quantitates minores nihilo! He showed, in this concep- tion, how the primative operations of Addition and Subtraction, with their distinguishing signs, gave out another infinite scale in opposite directions from zero; and in this pro- found exposition of + and —, he is followed as closely by Euler as if the German phi- losopher had written with Napier’s manuscript before him. In some particulars, how- ever, the modern treatise is superior to the ancient fragment. In the jirst place, it pos- sesses that perfect system of algebraic notation which, between the dates of Napier’s work and Euler’s, had been successively moulded in the hands of Vieta, Girard, Wallis, Har- riot, Descartes,and Newton. In the nezt place, Euler has a chapter upon Decimal fractions, and three chapters upon Logarithms, so that his system is complete and Napier’s is not. We shall find, however, that the important subject of notation was not left untouched by our philosopher ; and as for the systems he omits, what made him throw aside and leave unfinished this beautiful institute of numbers, but that he paused to create those very sys- tems, that he did create them,—and died. / In the second book, Napier comes, as he says, to particulars. ‘Through these I must follow him less closely, but shall endeavour to select what is curious and interesting. In the first chapter he proposes a third division of computation, and I shall translate the most of it, as it contains his definitions, and also a beautiful statement of the Indian no- tation, before that had been enriched by its European, or we may say Neperean stores. “¢ In the third place, computation is either of verinomial, or jfictinomial, otherwise hypo- thetical quantities ; and hence logistic is either of verinomes, which are treated of in this second book, and also in the third; or of jictinomes, otherwise algebraics, concerning which the fourth book treats. Veriomes are quantities defined by the actual terms in which their multitude or magnitude is expounded ; and they are either discrete, i. e. nam- ed in discrete number ; or concrete, 7. e. named in concrete number. Hence verinomial logistic is either of discrete quantity, and called Arithmetic, of which this book treats, or INVENTION OF LOGARITHMS. A777 of concrete, called Geometric (geometrica,) of which in the third book. Arithmetic, therefore, is the logistic of discrete quantities by discrete numbers. A discrete number is that which is measured by its single individual number. A discrete number is either whole or broken. Hence arithmetic is of integers and fractions. An integer is that which is measured by its own individual unity. Every idiom supplies its own vocal nomination of integers; as, in Latin, unum, duo, tria, quatuor, &c. But the written names of integers, or their notation, are these nine significant figures, 1, 2, 3, 4, 5, 6, 7, 8, 9. These signify various numbers, according to their change of place. Be- sides these nine figures, there is the circle 0, which has no signification wherever it is placed, but is destined to supply the vacancies. The series of places is considered from right to left, in the first of which the figure is named by its own value as above; in the second place, by its tenfold value; the third, a hundredfold; and so on in in- finitum, always progressing by a tenfold increase.” After giving examples, our phi- losopher proposes, for the sake of facility in reading great numbers, to point them off in threes; thus, 4.734.986.205.048.205, which he reads in Latin, guatuor millies mille millena millia millium . septingenta triginta quatuor millies millena millia millium . non- genta octoginta sex millena millia millium . ducenta quinque milla millium . quadraginta octo millia . ducenta et quinque. In the second chapter, he passes from nomination and notation to computation, and dis- plays the operations of Addition and Subtraction, taking his first example from the book of Genesis. The third and fourth chapters are devoted respectively to Multiplication and Division, and he shows the most perfect command of all these operations. He gives the well-known multiplication table. The fifth chapter is entitled, “‘ Miscellaneous short methods of Multiplication and Division.” In this occurs a distinct genesis and notation of Decimal fractions in Arithmetic, and perhaps the earliest on record. Ourphilosopher observes, that to divide any number by a divisor composed of unit and cyphers is easily effected by striking off so many figures from the right of the partiend, as the divisor con- tains cyphers; and he directs the figures so struck off to be placed above a line as the numerator of a fraction having the divisor for denominator ; and the fraction thus form- ed to be adjoined to the remainder of the partiend in order to form the quotient. The example he gives is, 865091372, to be divided by 100, and, according to the above rule, 8650913,72, is the quotient. Napier goes through this operation apparently unconscious of the important nature of the fraction thus obtained. Had he proposed simply to point off the figures deducted, so as to separate the right extremity, or unit’s place, of the re- maining integers from the broken numbers, he would have obtained his quotient by the most compendious rule possible, and at the same time have given his own notation of De- cimals, and that now in use. But the system was comparatively valueless in Arithmetic until the Logarithms appeared, and it is obvious from the above example that Napier’s ma- nuscript must be referred to a very early date. Clearly he had not seen the work of Stevinus, which he afterwards mentions in Rabdologia, and had formed no conception 478 HISTORY OF THE of his system of Logarithms, which, indeed, may be called the parent of the system of Decimal fractions. In chapter sixth our philosopher, with a fearless composure becoming the conqueror and king of numbers, enters the formidable field of involution and evolution. This, as we have seen, he terms radical multiplication, partition, and extraction. Kuler himself had not a more thorough command of the relative quantities, root, power, and exponent, than Napier had of radix, radicatum, and index. His opening statement of involution is less per- plexing than that of the illustrious German, whose statement might leave the student at a loss to know why the square of a number is called the second power, seeing Euler at the same time informs him that a power of a number derives its dignity from “the number of times it is multiplied by itself,” and that “‘ we obtain a cube by multiplying a number twice by itself.” Napier creates no such perplexity at the outset, for he commences by saying that the first step in the process of involution is to “* multiply wnzt by the root, which mul- tiplication returns the root itself; secondly, multiply that by the root and the duplicate [%. e. square or 2d power] is raised, and so on, according to the quality of the index; thus if 235 is to be multiplied to the index 4, [7. e. raised to the 4th power] first multiply unit by the root 235, which gives 235; multiply that again by the root, and 55225, the duplicate, is obtained,” &c. ‘* Hence,” he adds, “ radical multiplication repeated any number of times from unity is the same thing as to multiply together so many equal roots ; thus, 235 four times multiplied from unity is the same thing as 235.235.235.235 multi- plied into each other ;” a law which now would be thus generally and shortly expressed at=axayxaxa. Napier, indeed, had not arrived (and be it remembered that he is writing before Vieta, Harriot, and Oughtred, and when “ algebra was not cultivated at all in this country,”) at that powerful notation without the aid of which it was impossible for him to takesome more recent views of the exponential or potential system. He did not possess the algebraic refinement of working known quantities by means of other symbols than the significant digits, or of expressing powers by small letters instead of numerals and initial signs. He did not, for instance, consider aaaa as (to use his own term) the quadruplicatum of any number a ; far less did he consider the same quantity in this form, a‘, While he had not the “eral notation of powers, neither had he the numeral no- tation of indices; for although, in explaining their genesis, he named the indices, one, two, three, &c. and even noted them 1, 2, 3, &c., yet he did not systematically attach them to the root for the expression of the power. ‘To have done so would have been to have established the Cartesian notation, whose epoch is 1637. But in each defini- tion he shows his thorough command of the subject, and how capable he was of reap- ing every laurel in that great field of analytical inquiry which notation opened to his suc- cessors. For instance, the exponent of a power is thus defined in modern science: ‘ Ex- ponent of a power in arithmetic and algebra denotes the number or quantity expressing the degree or elevation of the power, or which shows how often a given power is to be divided by its root before it be Beppant down to unity or 1; it is otherwise called the INVENTION OF LOGARITHMS. 479 index. Exponents, as now used, are rather of modern invention,” &c.—(Hutton’s Math. Dict.) Now, although Napier had not the algorithm which opened the arithmetic of ex- ponents, (and which Dr Hutton so unaccountably says, “led the way to the invention of Logarithms,”) his view of that important quantity is precisely what is here stated. He says, “‘ the number of the index, or quality of the root, is obtained as well in descending from the radicate to unity by partition, as in ascending from unity to the radicate by mul- tiplication, for in either case the number of the operations is the index and quality of the root.” We must now turn to his chapter of the extraction of roots; a subject of which it has been observed, that among all the questions which the developement of our ideas of number places in review before us, there is none which, independently of the importance of the solution, has a greater tendency to excite the curiosity of every mind born for calcula- tion; it is comparatively easy to raise roots to powers, but when we demand the roots back again it is not so easy to obtain them. ( Bertrand.) Accordingly, the seventh chapter of the second book of Napier’s manuscript is entitled “ of finding the rules for radical extraction ;” and here our philosopher is disclosed to us at the very confines of the Bi- nomial ‘Theorem. “‘ Every root,” says he, “ has its own appropriate and particular rule of extraction. Each rule of extraction consists in resolving the radicate into its supplements (in swa supple- menta.) ‘The supplement (supplementum) is the difference between two radicates of the same species. Thus 100 and 144 are both duplicates [squares, ] the one of ten and the other of 12; and the difference between them is 44, which is the true supplement of the foresaid radi- cates. Supplements are as various, therefore, as the varieties of the species of radicates and roots. There is one rule for finding the supplements of duplication and of the extrac- tion of the bipartient root, another of triplication and the extraction of the tripartient root, and so on of all the rest. But my triangular table,—filled with little hexagonal areas, having, on the right side, a series of units inscribed, and on the left a series from unit in- creasing by unity, and descending from the vertex; every one of the little areas within containing a number each equal to the sum of the two numbers placed immediately above it,—teaches the rules of finding the supplements of all radicates and roots.” “ Let A, B, C, be a triangle, of which A is the left angle, B the vertical, and C the angle to the right. By so many species of roots as you wish the table to contain, into twice as many parts, and one more, divide each side of the triangle ; for instance, in order to extend it to 12 species of extractions, let each side of the triangle be divided into 25 equal parts; then beginning from the base A C, draw 12 parallel lines within the triangle, connecting the sides by the points in them alternately taken: in like manner, begin from the side A B, and draw 12 parallel lines betwixt the alternate points of the base, and the side B C, extending the lines beyond the side B C, about the space ofan inch ; ex- actly in the same manner draw the lines betwixt the side B A and the base, extending 480 HISTORY OF THE them an inch beyond B A; and you will have the triangle filled with little hexagonal areas. Of these, the 12 to the right, and next the line B C, must each have unit inscrib- ed within it; those on the left must have the numbers 1, 2, 3, 4, &c. as far as 13, (ex- clusive) successively inscribed in each, descending in their order from the vertex B to the angle A; then each interior hexagonal remaining vacant must have inscribed the sum of the two numbers immediately above it ; thus, under 2 and 1, must be written 3, under 3 and 3, 6; under 8 and I, 4, and so on down to the heel of the table. Lastly, the table must be titled, on the left side above the second hexagonal (2,) let there be written pre- cedentis, above the third hexagonal, (3,) write duplicatum preecedentis, and so on as far as duodecuplicatum. On the right hand of the table write above the first hexagonal, succe- dens, above the second, duplicatum succedentis ; above the third, triplicatum succedentis, and so on down to éredecuplicatum ; as you have here in the diagram of the table itself written below. ” AN + /& /9 & [s ONG OOO Oy erent NY. “To every supplement two parts of the root correspond, the one part consisting of one The above diagram is a fac-simile from the manuscript.

The supplement and these parts of the root mutually compose each other, and are built up together, as will afterwards appear.” * In the rest of this chapter our philosopher lays down rules for reading the table by means of the titles annexed, and refers generally to its use in the extraction of roots. In the two following chapters, namely, the eighth and ninth, he shows its application more particularly, and affords a long and profound exposition of the difficult doctrine of evo- lution. The remarkable similarity between Euler’s Elements and Napier’s is even observable in the tables that illustrate the respective works; and if Euler’s arrangement had been as purely and philosophically symmetrical as Napier’s, (in which circumstance, however, it is far inferior,) his work would almost have seemed a modern transla- tion of the ancient manuscript. If our philosopher were to be any where complete- ly thrown out in the comparison, that might have been expected to occur in Euler’s chapter of the Binomial Theorem ; yet there I find the latter, after examining the “ im- portant question how we may find, without being obliged always to perform the same calculation, all the powers either of a + b, or a— 4,” gives the following table as that which discovers the law by which binomial coefficients are formed. * Dr Wallis, in his Algebra, 1685, reviews Oughtred’s Clavis Mathematica, first published in 1631, (fourteen years after Napier’s death,) and in the chapter of the nature and composition of powers, gives a table of powers from Oughtred’s work, of which I find the counterpart in Napier’s manuscript, but further extended. Napier gives it immediately after his arithmetical triangle, and uses it pre- cisely for the purpose Oughtred did. “ From hence,” says Wallis. “ we may take, without more adoe, the nearest root (quadratick, cubick, &c. respectively,) of any number whose root requires not more than one figure, and the respective power of any such root. But because in extracting the root of great numbers, it will be necessary to seek out the root by piece-meal, (as we do the quotient in divi- sion,) he doth afterwards consider the root as consisting of two parts, A + E, (which he calls a bino- mial root,) whereof one part is supposed to be already known, (or to be found by the preceding table, ) and the other unknown, to be found by the following table, which he calls his latter table of powers.” This latter table is Napier’s binomial table; but under the notation of Vieta, whose symbolical me- thod, called specious arithmetic, was unknown to Napier, and forms an important step in the progress of notation. There is an old-fashioned, but excellent work, entitled, “A New System of Arithmetick, Theo- rical and Practical, by Alexander Malcolm, teacher of the mathematics at Aberdeen, 1730,” contain- ing a full exposition of the Binomial Theorem, wherein I find a remark that illustrates our philoso- pher’s explanation of his diagram. “ These expressions of powers of a Binomial root shew us how the difference betwixt any two similar powers is composed of the various powers and multiples of any one of the roots, and the difference betwixt the roots,” &c. 3P 482 HISTORY OF THE Powers.

From this table Euler proceeds to deduce the Binomial Theorem itself, and concludes his chapter with these words, “ this elegant theorem for the involution of a compound quantity of two terms, evidently includes all powers whatever ; and we shall afterwards show how the same may be applied to the extraction of roots.” It is obvious from Napier’s expressions, ‘* Tubella nostra triangularis areolis hexagonis referta,” that his beautiful diagram is perfectly original in his hands. A disposition of numbers upon the same principle, for the extraction of roots, was first conceived by Sti- fellius in this form.

I think it is equally certain that he had never seen the Arithmetica Integra of Stifelltus.* While he praises the former author in Rabdologia, I cannot find that he any where mentions the latter, whose very curious work, however, must have excited his warmest admiration had he met with it. The celebrated Blaise Pascal, one of the most profound minds ever created, has in more modern times obtained the highest praise for his Arithmetical Triangle, which, as the reader will easily perceive from the following diagram of it, is just Napier’s table under a less beautiful form. d<| PSP Ss % SI PaPapaPeP aps] | Montucla, in his History of Mathematics, refers to it in these words; “ Quelques questions sur les jeux lengagérent (Pascal) 4 approfondir les combinaisons, et ses medi- tations sur ce sujet donnerent lieu 4 Vinvention de son triangle arithmetique, au moyen duquel il résoud divers problémes sur cet objet. Il écrivit sur cette matiére un traité qui paroit avoir été achevé vers 1653, quoique imprimé seulement en 1665. Les usages de ce triangle arithmétique sont nombreux, et c’est une invention vraiment originale et singu- liérement ingénieuse.” ‘The properties of this triangle are so intimately connected with the Binomial Theorem that Bernoulli, on that account, claims for Pascal the merit of being its first inventor. In his annotations upon a work of Mr Stone, upon the infinite- simal analysis, where the latter speaks of ‘“ that marvellous theorem,” Bernoulli notes, ‘* Pour Velevation @un binome a une puissance quelconque. Nous avons trouvé ce merveil- leux theoréme aussi-bien que Mr Newton, d’une maniere plus simple que Jasienne. Feu M. Pascal a été le premier qui Ya inventée.” (Johan. Bernoulli Opera, iv. p. 173.) Baron Maseres (Scriptores Logarithmicit, Vol. iv.) republished Pascal’s works on Arithmetic and Algebra, and says, “ ‘These works are so full of genius and invention, that I thought I should do a service to the mathematicians of Great Britain, by republishing them in * Dr Minto acutely observes, “ Not only Napier’s manner of conceiving the generation of the Lo- garithms, but his having computed that species of Logarithms which has been described, before the common Logarithms occurred to him, is a convincing proof of his not taking the Logarithms from the remark of Stifellius.” 484 HISTORY OF THE this collection. Some of them, and more especially his Arithmetical Triangle, have a considerable connection with Logarithms, by affording a good demonstration of Sir Isaac Newton’s Binomial Theorem in the case of integral and affirmative powers, which is of great use in the construction of Logarithms.” Very probably the invention was original in Pascal’s hands, and the application to games of chance seems entirely his own. It is a curious fact, that Napier’s friend, Henry Briggs, to whom the manuscript we are considering is addressed, did also, in his Trigonometria Britannica, give a table of the same description; and Dr Hutton, when noticing this work in his History of the Con- struction of Logarithms, has accordingly claimed the Binomial Theorem for Briggs. He says, after giving some account of the table and its properties, “ this is the first men- tion I have seen made of this law of the coefficients of the powers of a binomial, com- monly called Sir Isaac Newton’s Binomial Theorem, although it is very evident that Sir Isaac was not the first inventor of it; the part of it properly belonging to him seems to be only the extending of it to fractional indices, which was, indeed, an immediate effect of the general method of denoting all roots like powers with fractional exponents, the theorem being not at all altered,” &c. Briggs’ table, which he called Abacus May yensos. is in this form, only carried further on.

We have elsewhere ventured to call him a satellite of Napier’s, and fairly enough, as his memory is chiefly logarithmic, and his persevering pilgrimages to the old tower in Scotland is an ample justification of the epithet. But Briggs has evinced in his two logarithmic works a mind capable of great mathematical conceptions. * In re- ference to the arithmetical triangle, he appears to have been the first to point out a * The kind assistance of an Oxford friend enabled me to ascertain, with tolerable certainty, that there are no traces among Briggs’ papers, preserved at that university, of a correspondence between him and Merchiston; probably he found the Baron a better host than a correspondent. Among Briggs’ papers in the British Museum, there is one entitled Imitatio Nepeirea, sive applicatio omnium fere regularum, suis Logarithmis pertinentium, ad Logarithmos, supposed to have been written imme- diately after the publication of the Canon Mirijicus. INVENTION OF LOGARITHMS. 485 particular law of that configuration which brought him as close to the Binomial theo- rem as the notation of his day rendered possible. The passage is remarkable, and as his work is rarely to be met with, I shall give it here. ‘‘ Numerus quilibet est ad suum Diagonalem, ascendendo versus sinistram, ut verticalis primi ad Marginalem secundi. Nu- meri in Columna A sunt ad suos Diagonales in B ascendendo, ut 2. ad Marginalem se- cundi. Hine sequitur numeros margini dextro adjacentes, reliquosque deinceps proximos, » posse inveniri et continuart quo usque visum fuerit ; licet totus Abacus a Capite non sit adscriptus.” I have looked anxiously, but in vain, through Napier’s manuscript to dis- cover some expressions indicative of his observation of this important law of propor- tion actually existing in the table he had formed. There is, however, no question that his triangle is what would be now called a table of coefficients of the powers of a binomial, which he framed for its most important application, that of extracting roots. In doing this he was certainly at the confines of the Binomial Theorem. Had he only recorded the observation of Briggs, it must have been admitted that he had ac- tually stated the leading principle of that elegant theorem, which is engraved upon the tomb of Newton as one of the greatest of his discoveries. The observation, which leaves that laurel with Briggs, (and which Napier may have seen, though he did not state it,) amounts to this, that, by a certain law of proportion existing betwixt the figures of the diagram, which law he points out, all the terms of the binomial quantity could be successively deduced, or raised, from the second term (the coefficients of the first and second terms being always known,) without the necessity of finding the intermediate and preceding powers. The application of this law (which Briggs verbally stated) is that algebraic generalization of the principle of Napier’s triangle which supersedes the ne- cessity of actually composing the whole table in order to obtain the terms and successive powers of a binomial root; and upon the strength of Briggs’ observation of that law Dr Hutton claims the Binomial Theorem for him, certainly with better reason than Bernoulli does for Pascal. But the value of it is really dependent upon a play of symbols not known in the time either of Napier or Briggs. What was necessary in order to make the property, which the latter unquestionably pointed out, a valuable extension of the arith- metical triangle, was to have the means of stating it in this form, 1 x ~ = Be = = x ek &c. being Sir Isaac Newton’s genesis of the binomial powers in question. So far, indeed, the Prince of Mathematicians only made the algebraic application of the principle of the figurate table in the case of integral quantities, to which alone the triangle is applicable. But Dr Hutton, probably for the sake of planting so fine a laurel upon the brow of Briggs, seems inclined to slur over amost important extension of the Binomial Theorem, when he says, ‘“ Sir Isaac was not the first inventor of it, the part of it properly belong- ing to him seems to be only the extending of it to fractional indices, which was, indeed, an immediate effect of the general method of denoting all roots like powers with fractional exponents.” ‘True it was an improved notation that led Newton to consider the theorem as he did, and moreover, to expand it into an infinite algebraic series, which, without that notation, it were impossible to have done; but in this it was, that, to use the phrase 486 HISTORY OF THE of his last biographer, Newton must be acknowledged as ‘‘ the General who won the vic- tory, and therefore wears the laurels.” In his hands the binomial table of Stifellius, Napier, Briggs, and Pascal (each one of whom appears to have invented it) was expanded into the Binomial Theorem par excellence. What he did beyond his predecessors is some- what analogous to Napier’s merit when he generalized the logarithmic principle (pre- viously observed by Archimedes, Stifellius, and others,) into a system of universal appli- cation and omnipotent power. In that comparison, however, the important distinction must be kept in view, that Newton’s generalization of the table of coefficients was forced upon the attention of such a mind by the then ripened doctrine, and notation, of powers and exponents, the very medium through which, in like manner, he must have detected the Logarithms. Napier, on the other hand, instead of using that means to extend the principle of Archimedes into a system of common Logarithms, and before such means was in existence, took a totally different path of his own construction, and tore the veil from a transcendental system of Logarithms, thus disclosed, as it were, before its time. Although the Binomial Theorem is “ so very closely connected with the subject of Logarithms as to be the foundation of the best methods of computing them,” (Maseres,) and although our philosopher approached the confines of it in his beautiful diagram, (a form perfectly original,) these circumstances must not be supposed to connect with his great invention. In that path he could do nothing without algebraic notation, which in his day was totally inadequate for such refined purposes. The analytical language may be said to have first dawned in the works of Vieta, which only commenced to be spread abroad, and to give an impulse to science after Napier’s career was closed. It is of consequence, then, to see if, in the manuscript we are considering, there be any indi- cations that Napier felt the trammels of a rude notation, and struggled to remove them. As his system of numbers was never finished, and is only now first noticed to the world, of course what he did in this manuscript can form no link in the progress of science, and can be only referred to in further illustration of the mind that invented the Logarithms. But it will be acknowledged, by all lovers of science, to be a very striking and interesting circumstance, if, as we shall immediately show to have been the case, Napier not only de- termined to become the liberator of the numerical scale, but had turned his powerful mind to algebraic notation, with the same premeditated intention of reforming that. I am not aware that any writer before his time had made the systematic attempt now to be noticed. Immediate necessity, and accidental ingenuity, added very sparingly to the ab- breviated language of algebra during the period between its introduction into Europe and when Napier commenced a work of extreme beauty and high conceptions, which, had he published it, even in its unconcluded state, must have given a decided impulse to science, and Britain a distinguished place in the history of Algebra, independently of the Logarithms. In his consideration of radical partition, and extraction of roots, Napier did not fail to observe, most profoundly and successfully, a species and property of numbers exceeding- ly curious, and of high importance in the science. ‘The quantities alluded to are the INVENTION OF LOGARITHMS. 487 roots of those numbers whose roots cannot be numerically expressed ; and for this rea- son, that a root is that quantity which is contained in another quantity any number of times exactly, 7. e. without a remainder less than the root itself; and there are some num- bers that contain no number whatever any number of times without a remainder. An ordinary mind might be apt to conceive that such quantities had no roots, according to the definition of that term. Mathematicians have decided otherwise. The roots lurk in those quantities, though they cannot be extracted; they may be hunted into a corner, but they cannot be caught; or, to use Napier’s expressions with regard to them, they may be named, but they cannot be numbered. Having decided that such latent quantities have a real existence, mathematicians, of course, will not suffer them to remain in idleness, or unsubjected to the dominion of science. They have been called irration- al quantities or surds, and hence the arithmetic of surds has become a special and important department of numbers. No man before or since his day, knew better how to hunt a surd than John Napier. He was thoroughly master of their whole philosophy, and the manuscript before me contains, perhaps a more beautiful and complete exposi- tion of their arithmetic than has ever been published. Consequently, this very curious property had not escaped him, that a surd root, though it cannot be expressed in finite number, lies between two other numbers that can be so expressed, and whose terms can be brought closer and closer to each other by infinite approximations, without, however, being capable of catching the latent surd. To give an easy example,—the square root of 9 is 3, because 3 times 3 is 9; but what is the square root of 10? In other words, what is the number which, multiplied by itself, makes 10? Not 3 times 3, that is too little ; nor 4 times 4, that being too much. But the doctrine of fractions enables us to express numbers betwixt 3 and 4, and, consequently, nearer to each other than these. The ap- proximations, however, are still found to be terms, the one too great, and the other too small, to express the surd sought ; and the curious property is, that the fractional terms may be brought closer and closer together by an endless approximation, and still the surd shall be latent between them. Thus the actual existence of the quantity is ascertained, but it can only be expressed by two separate finite terms indicating its position, or by some special symbol invented to represent it. Now it was to the notation of these surds that Napier, in that department, first turned his attention, as such quantities seemed pe- culiarly dependent upon a symbolical notation. ‘The notation he proposed was never published ; and I shall premise the translation with some notices of the state of irrational expressions after his day, and, indeed, as it exists now. Dr Wallis, the great contemporary of Newton, in his Algebra already quoted, after explaining the nature of a surd root, adds, “ in such case we must either content our- selyes with an approximation instead of the accurate value, or else with such note of ra- dicality as shall intimate what is supposed to be, but cannot accurately be expressed in numbers. As /2,or,/q2, the square root of the number 2. /¢3, the cubick root of the number 3. Which supposed roots, thus designed, cannot in numbers be ac- curately expressed, there being no effable number, integer or fraction, which, being mul- 488 HISTORY OF THE tiplied into itself, can make 2; or, beg cubically multiplied, can make 3.” Euler, in his Algebra, says, ‘“ there is a sort of numbers which cannot be assigned by fractions, and which are, nevertheless, determinate quantities ; as, for instance, the square root of 12; and we call this new species of numbers irrational numbers ; they occur wherever we endeavour to find the square root of a number which is not a square; thus, 2 not being a perfect square, the square root of 2, or the number which, multiplied by itself, would produce 2, is an irrational quantity ; these numbers are also called surd quantities, or incommensurables. ‘These irrational quantities, though they cannot be expressed by fractions, are, nevertheless, magnitudes of which we may form an accurate idea; for, however concealed the square root of 12, for example, may appear, we are not ignorant that it must be a number which, when multiplied by itself, would exactly produce 12 ; and this property is sufficient to give us an idea of the number, since it is in our power to approximate towards it value continually. As we are, therefore, sufficiently acquainted with the nature of the irrational numbers under our present consideration, a particular sign has been agreed on to express the square roots of all numbers that are not perfect squares ; which sign is written thus /, and is read the square root.” A great improvement, how- ever, in this notation became established between the time of Wallis and Euler, and that was to express the number of the root, or the order of the power, by a numeral index placed within the radical sign, instead of the cumbrous repetition of initial letters. Besides this improvement there is a more modern alternative notation of surd roots. Euler, in his chapter “ of the method of rid dirk oe irrational numbers by fractional exponents,” shows “ that a 4 is the same as ied a,” and so on; and then he adds, ‘‘ we might therefore entirely reject the radical signs at present made use of, and employ in their stead the fractional exponents which we have explained ; but as we have been long accustomed to those signs, and meet with them in most books of algebra, it might be wrong to banish them entirely from calculation ; there is, however, sufficient reason also to employ, as is frequently done, the other method of notation, because it manifestly corresponds with the nature of the thing.” It must also be observed, that, notwithstanding “ the rule, that we must adhere to one notation for one thing,” the radical notation in question has not been exclusively devoted to the same species of quantity. Kuler, in his chapter “ of roots, with relation to powers in general,” and, speaking of rational roots, takes occasion to ex- hibit the different roots of the number a, with their respective values. a } [oa Inet Va | | 3d Sy i t isthe + 4th froot of + g | sth : a | 6th | a and so on,” INVENTION OF LOGARITHMS. 489 being the same radical signs that are taken to express surds. Thus it appears that even at present the notation of such irrational quantities is not of a very determined character ; but, in the first place, possesses an alternate mode of expression ; and, in the second place, a set of radical signs, shared in common with an opposite species of quantity. We may now turn to Napier’s consideration of this subject in which we shall find, as usual, the most unequivocal proofs of his original and penetrating genius. In the fourth chapter of his first book, our philosopher, after explaining the genesis of asurd root, and of the approximating terms between which it lurks, (sve supra, p. 467,) adds, “ but geometricians, studious of greater accuracy, choose rather to prefix the sign of the index to the radicate itself, than to include the root between twoterms; thus they note the tripartient root of nine in this manner, ,/ c9, which they pronounce the cube root of nine. I, however, note it thus, Lye 9, and call it the ¢ripartient root of nine; these signs I shall discuss more fully in their place.” In the ninth chapter of his second book, entitled, “ Of the method of amending imperfect extractions,” our philosopher enters minutely into the subject of the approximating fractional terms, and teaches how to express an irrational root with the least sensible error. ‘ So that,” to take the result of one of his examples, ‘“ without any sensible error, especially in practical science (in mechanicis,) the bipartient root of 164860 may be called 406,2;4,, or 406,25.” He afterwards observes, “ these methods, as they do not make imperfect roots perfect, but merely render them less imperfect, are more pleasing to practical men (mechanicis) than to mathematicians, as I have noticed in C. iv. Lib. i. Geometricians, therefore, prefix the appropriate sign of the root to such radicates as have no roots in numbers. Hence, from the radicates with these signs prefixed, arises the first species of geometrical numbers, called wninomes. As in the above example of the duplicates 164860 and 50, they neither extract the bipartient roots, because they pos- sess none precisely in numbers, nor do they amend the imperfect extraction; but they prefix to the number the sign of the root to be extracted, which they call the square root (quadratam,) thus, ,/ Q 164860, and ./Q50, or thus, ,/¢ 164860, and ,/¢q50, which they pronounce the square root of the number 164860, and the square root of the number 50. I, however, note them thus, | | 164860, and |_]50 ; and pronounce them the bipartient root of 164860, and the bipartient root of 50. So the tripartient root of the number 998 they neither extract, as it is not in numbers, nor amend, but thus note, ,/ ¢ 998, and pronounce, the cube root of 998. I, however, note it thus, | 998, and pro- nounce it, the tripartient root of 998, as I shall discuss more amply in its place. How- ever, these are called wninomia, or medialia, and are the foundation of Geometrical Logistic. They shall be treated of, therefore, in the following book; here it is sufficient to have pointed out their origin.” In order to connect this subject, I shall pass immediately to the third book here re- ferred to, reserving in the meantime what remains to be noticed of the first. It is en- titled, Liber tertius de Logistica Geometrica,* Cap. i. Unfortunately it is a fragment, being * J am not aware of a department of science known under that term now. Probably the best ex- planation of it is that afforded by the fragment itself. ; 3Q 490 HISTORY OF THE all that his son Robert could find among his papers upon the subject, as he notes at the end of his transcript. It is, however, so original and full of genius that no apology need be offered for giving our readers a literal translation of the whole of it. «¢ In the preceding book I have taught Arithmetic; here in order follows Geometrical Logistic. The computation of concrete quantities by concrete numbers is called Geome- trical Logistic. Thus 3*, if it relate to three lines, each a finger-breadth (digitales) thus, , is a discrete number. When, however, it refers to a concrete and continuous line of three finger-breadths, such as this #__-_+ 41 4, it is called a concrete number ; but this zmproperly, and subject to reason. The roots of num- bers which cannot be measured by any number, integral or fractional, are properly, and in themselves, called concrete numbers. ‘Thus the bipartient or square root of seven is greater than two, less than three, and with no fraction in the universal elements of broken numbers is it equal or commensurable; it is therefore properly called a concrete number. So the tripartient, or cube root of the number 10 is not a discrete number, nor commensurable with number, but is concrete; and so are an infinity of other roots of numbers, commonly called surds and irrational numbers (surdos et irrationales.) ‘These concretes arise out of the extraction of roots from numbers in which those roots are not seated ; as I have already noticed, C. zv. Sect. 8, Lib. i. and C. iz. Sect. 7, Lib. ii. Hence, from the variety of roots arise various notations and nominations of concretes. As the bi- partient root of seven, which is usually called the square root of seven (quadratam,) I note in this manner Lal and pronounce the bipartient root of seven. So the cube root 10, I pro- nounce the tripartient root of ten, and write it thus E 10. So the quadripartient of 11, I note thus ss] 11.

Of * Napier’s notation is written about this size in the manuscript, apparently for the sake of distinct+ ness in teaching; but it would appear that he meant it to be much smaller in practice, as it some- times is written of a diminutive size, and even attached to fractions, thus u= yand Te 5 INVENTION OF LOGARITHMS. 491 nomials some are uninomials, others plurinomials. A uninome is the same as a single concrete number, proper or improper. Hence it follows that a uninome is either a single simple number, or any root of a single simple number. Thus 10 is a simple number, and, by geometricians, in frequent use as a uninome. So [| 10, ie 12, a) 26, and such like, are roots of numbers, and, when taken by themselves, are truly uninomial radicates. *¢ Now, since it is the case that a uninomial radicate may be the root either of an abun- dant or defective number, and its index may be either even or odd, from this fourfold cause it follows, that some uninomes are abundant, some defective, some both abundant and defective, which are called double, and, finally, some are neither abundant nor de- fective, which are called imaginary (nugacia.) I have already (Lib.i. C. vi.) laid the foun- dation of this great algebraic secrete ; and although never, that I know of, hitherto revealed by any one, how much it will enrich this art and the rest of the mathematics, shall after- wards be manifest. * ‘In abundant and defective uninomes, it is not of much consequence whether the ap- propriate sign be prefixed or interposed; it is better, however, to prefix it. But in double and imaginary uninomes, the appropriate sign must be always interposed. An example of the first case is [| 10, or (which by C. vi. Lib. i. is the same thing) & + 10, an abundant uninome. An example of the second case is lene 10, a defective uninome. An example of the third case is |_] 10 or |_| + 10, (being, as above, the same,) which * This certainly has no connection with the Logarithms, and most probably refers to some of those profound views in algebra, and the theory of equations, which compose the triumphs of subsequent philosophers. Unfortunately, the algebraic part of the manuscript is not entire; but from what has been preserved, it is quite obvious that Napier was capable of any thing in that science, so far as the existing notation made it possible for him to advance. Without attempting to say what Napier here particularly contemplated, (which I leave for the learned,) some interesting illustrations of what he actually lays down may be derived from the history of algebra. It must be kept in mind, that what he calls abundant and defective quantities are now known under the terms positive and negative ; (supra, p. 469, &c.;) as for imaginary quantities, | am not aware that any one before the date of this MS., or for long after it, was so bold or profound as to give them their important place in calculation. Accordingly Playfair, speaking of Girard, in the passage already quoted as to quantities less than nothing, (supra, p. 469,) whose Invention Nouvelle en Algébre was printed in 1629, says, “ the same mathematician conceived the notion of imaginary roots.’ Dr Hutton observes, “ Albert Girard gives names to the three kinds of roots of equations, calling them greater than nothing, less than nothing, and envelopée, as ./— bc ; but this was soon after called imaginary or impossible, as appears by Wallis’ Algebra, p. 264, &c.” Yet we find that Napier considered, and was expounding, such quantities, in their philosophy, nomenclature, and notation. So much is this the case, that a great part of Euler’s 13th chapter “ of impossible or imaginary quantities” may stand, as usual, for a translation of Napier’s dis- cussion of the same subject. The passages are too long to quote; but any one who takes an interest in the history of algebra, or the genius of Napier, will be struck with the similarity betwixt that chapter of Euler and what we have quoted at p. 471 from our philosopher’s manuscript, and also above. Euler even adds the same warning against confounding the radical signs: “ We must not,” he says “ confound the signs + and —, which are before the radical sign /, with the sign which comes after.” 492 HISTORY OF THE signifies both an abundant quantity multiplied into itself, and yielding + 10, and also a defective quantity multiplied into itself, and yielding + 10; or, for the ‘sake of a more lucid example [_J9, or {al + 9 is as much + 3 as —8, according to what I have already demonstrated, Lzd. 7. C. vi. An example of the last case is LJ — 9, which is merely imaginary, and signifies nothing that either abounds or is deficient, for defective nine has no bipartient root, as is made plain in Lid. «7. C. vi. s. b. “¢ In imaginary quantities special care must be taken that the sign minus —, to be in- terposed, be not prefixed. ‘Thus, if for { be — 9, which is the bipartient root of minus nine, (minuti novenarit,) and infers an absurd and impossible quantity, there be taken — |] 9, which signifies a quantity less by the square root of nine, a great mistake will be committed ; for the bipartient root of nine, here abundant, namely, |_| 9, is double ; that is, + 3 and — 3; and therefore, a quantity minus these geminals + 3 and —3 will be geminal ; so that whoever for [J —9 writes — [| 9, puts forth a quantity of a geminal, or double signification, instead of a quantity absurd, impossible, imaginary, and of no signification (absurdo, impossibili, nugaci et nihil significante.) Take care, then, of such prevalent confusion. “ In all other uninomes (significant that is) it is the same thing whether the copula- tive sign be placed between the radical sign (signum radicale,) and the number, or prefixed to both; nor does it change the value of those uninomes to place the sign + before them or in the middle. Thus |_| 9, and [_] +9, and +. [_| 9, and + L_] +9, are all precisely the same, namely, as much + 3as—3. So [ sor: or} + 27, or + fat 27, or + lano7: have the same value as + 3 only. So is — 27, or + |_— 27, or — fe 27, or — fits + 27, have the same value as — 3 only. So imimaginary quantities, heal —9and+ {je 9 signify the same, as they both imply the same impossibility. But take care not to write in their stead —| fo or Sih ee 9, as in the preceding section I have admonished. ‘* So much for the affections of uninomes in themselves. The next consideration is the manner in which they stand affected to each other. Two uninomes (uninomia bina) are either commensurable with each other, or incommensurable. ‘Those are commensurable which are to each other as discrete or absolute numbers. Hence every absolute num- ber is commensurate with every absolute number. Moreover, two uninomes radicated alike, [consimiliter radicata, i. e. raised to the same power, or whose indices are alike, ] of which the oue simple number, when divided by the other, yields a number possessing such a root as the radical sign indicates, are said to be commensurable with each other in the ratio that the root indicates. Thus 5 and 7 are commensurable, because they are absolute or rational numbers. So, of the two uninomes radicated alike ia 8 and [_] PAs if the simple number 8 be divided by the simple number 2, the quotient is 4. Now the number four has a root whose sign is lel; that is to say, bipartient, and it is the num- ber 2. Therefore |_} 8 and |. | 2 are commensurable with each other in the ratio of the root, which is as two to one. Consequently, all other uninomes which cannot be redu- ced to this are incommensurable. ‘Thus [_ 12 and [ J 3, because they are differently ra- INVENTION OF LOGARITHMS. 493 dicated, are incommensurable. So L_] 6, et | | 2, (although radicated alike,) are incom- mensurable, because 6 divided by 2 produces 3, which wants the root whose sign is bal, that is, the bipartient. But 12 and he 4 are commensurable, because when reduced they are equivalent to 12 and 2, &c.” ** I could find no more of his geometrical pairt amonst all his fragments.” * I now return to the concluding chapters of Napier’s second book, of which it is only possible here to give a hurried and imperfect view. Having in the 6th, 7th, 8th, and 9th chapters disposed in the most brilliant manner of involution and evolution, our phi- losopher, never losing sight of perfect symmetry in his arrangement, again takes up, in chapter 10, the rules of proportion of integers. Referring to those already given in his first book, he now expounds several particular and compendious rules of proportion, of which one example may be selected, as being characteristic of the constant war he waged against the tyranny of derivative computation. “« There is,” says he, ‘ another compendious method without the omission of figures. Let all the given numbers of the question be arranged in their proper places above and below the line, as I have expounded in the general method proposed in C. v. Lib. i. Then let each of two numbers, one above the line, as if numerator, and the other below the line, as if denominator, be divided by the greatest common divisor until each of the nu- merators shall be to each of the denominators in the first or least ratio to each other, all the last quotients being noted. Finally, let the multiple of all the upper quotients be divided by the multiple of the lower quotient; this quotient will be the answer sought, and solve the question. Thus, if 4 builders construct a wall 6 feet high and 48 ells long in 42 days, it is demanded, in how many days will 5 builders erect a wall 9 feet high, and 50 ells long? Let all the numbers be arranged according to the rule laid down in C. v. Lib. i. and they will stand as on the margin. Then abbreviate the upper number 4, and the lower number 6, by 2, the greatest divisor, which gives 3 in this form —— Then divide 2 above, and 48 below, by the common divisor 2, which gives 1, and 24, in this form 1.9.90. | Then divide 9 and 3 by 3, which gives 3 5.3. 24. above and 1 below, in this “eqn et aes .

So you now have the familiar and tractable numbers 1.3.5.7. and 1.1.2. to be multiplied together, instead of the given numbers, which were somewhat bigger.

He carries them minutely through all the operations of addition, subtraction, multiplication, involution, evolution, and rules of proportion. It would occupy too much space to give any thing like a satisfactory abstract of these operations, in which the ele- gant and profound character of the work is completely sustained. This must again be observed, however, that his division of the subject of fractions clearly intimates, that at this time Napier had not considered decimal fractions as a distinct department. He says, ‘* of fractions, some are called vulgares, others physice.” He defines vulgar fractions as those ** whose denominators are various and free ; as, one-half, two-thirds, four-elevenths, &c.” He then explains that “ the denominator is that which names into how many equal parts unity is distributed ; the numerator is that which numbers how many of these parts are taken ; the numerator is pronounced in cardinal number, the denominator in ordinal, the numerator above the line, the denominator below.” He then refers to the fractions of frac- tions, and his own method of noting them; “ there are some improper fractions, he says, which are not expressly a part or parts of unity, but are the parts of fractions ; and these are called fractions of fractions. I note them by interposing the particle ex ; others note them by omitting the line or lines of the posterior fractions. Thus, two-fifth parts of three-fourth parts I note ? ex $; others note them thus, ? 7,” &c. * Napier defines physical fractions, “‘ the part or parts of a whole, divided by some ap- pointed and commonly received divisor, which its authors put in the place of denominator. Thus it hath pleased owr mint-masters to divide the pound of money, not into what number of parts you will, but into 20 parts, and to put shillings in the place of denominator ; so the Apothecaries divide the pound weight into 12 parts, which they name ounces, an ounce into 8 drachms, a drachm into 3 scruples, &c.; Chronologists divide the year into 12 months, the months into 80 days or thereabouts, the day into 24 hours, &c. ; Astronomers divide the degree into 60 prime scruples or minutes, the primes into 60 seconds, the seconds into 60 thirds, &c.” But Napier nowhere, in all his minute exposition of fractions in this work, refers to the system of decimals. The chapter of physical fractions closes his book of arithmetic, the last sentence of which must not be omitted,—“ And now to Gad, the Father Almighty, and in all His Numbers, infinite, immense, and perfect, be ascribed all the praise, honour, and glory, for ever and ever. Amen. Finis.” Napier, in the first chapter of his Arithmetic, refers to Geometrical Logistic as the subject of his third book, (the fragment already given,) and to Algebra, as treated of in his fourth book. It would appear, however, that although he has also left a manuscript treatise on Algebra, it is an earlier production than what we have been considering. * “Compound fractions are fractions of fractions, and consist of several fractions connected together by the word of; as 3 of 3, or 3 of 2 of 3.”—Hutton’s Math, Dict. A a INVENTION OF LOGARITHMS. 495 This is manifest from several circumstances. 1. It is entitled, “ The Algebra of John Naper, Baron of Merchistoun,” but not diver quartus, in correspondence with the other books. 2. Arithmetic is referred to in it; but there is no reference to his own book of Arithmetic, as unquestionably (according to his practice throughout the rest of the manuscript,) there would have been had that existed at the time. 3. This treatise is itself divided into two books; and while there is a systematic reference to its com- ponent parts, there is none whatever to the treatise we have considered. 4. Napier adopts in his Algebra the radical nomination and notation, which in the other treatise he had superseded by a superior system of his own; and there is here no reference to his peculiar notation of surds. There can be little doubt, therefore, that, although what we have reviewed was written before he had conceived the Logarithms, this trea- tise is a still earlier production. From the circumstance, however, that Robert Napier has paged the two books of Algebra continuously with the rest, it is probably that they are so much of what the philosopher intended to compose the fourth book, to which he alludes. Yet it is singular that there is no appearance of crude or youthful composition in this his earliest work. It is stampt with the same characteristics of simple exposition, profound views, and symmetrical arrangement as all his other productions. Our limits will not enable us to do it justice ; but some extracts from the first chapter, which he en- titles, “‘ of the definitions, the divisions of the parts, and the vocabulary of the art,” will afford an interesting specimen, and also evidence that his Algebra was written prior to his arithmetic. “ Algebra is the science which treats of solving questions of magnitude and multitude. It is twofold; the one part regards xominate quantities, the other positive. Nominate quantities are named from numbers, rational or irrational. Rational numbers are either absolute numbers, or fractions, of which arithmetic also treats. Irrational numbers are roots of those rational numbers which have no roots in numbers; and these, as they are quantities, also belong to geometry. The positive part of algebra is that which explicates quantities and numbers through the medium of fictitious suppositions, and of which I shall treat in the second book. In this first book I shall teach the first part of algebra, concerning nominate numbers and quantities. ‘There are three species of nominates ; uninomia, plurinomia, and universalia. Uninomia are either a single simple number, or any root of a single simple number. But the roots of numbers are various; therefore, for the sake of art and learning, they are expressed by characters prefixed, called radical signs (signa radicalia,) and noted thus :— nie: - radix quadrata. al Gs - radix cubica. J QQ, - = radix quadrati quadrata. 7 Ss; - radix supersolida. RUQC; - radix quadrati cubica. Nas, f= radix secunda supersolida. J QQQ, - radix quad. quad. quadrata. Me CO. - radix cubi cubica. et sic de ceteris in infinitum. 496 HISTORY OF THE Our philosopher then minutely expounds the various compositions and combinations of these radical signs and quantities, with their relations to each other. In the second chapter he commences their arithmetical operations with “ addition of uninomes ;” and thus, in seven- teen chapters, which compose this first book, he gives the most beautiful treatise on the arith- metic of surds perhaps ever written. His leading arrangement is always genealogical. He shows how uninomes are born of the extraction of roots that have no roots of numbers, of which his first part treats,—how, from the addition and subtraction of uninomes that are incommensurable arise plurinomes, of which his second part treats,—and how, from the ex- traction of the obscure roots of plurinomes arise universals, of which the third and last part treats; and then he adds, “so in like manner from universals arise universals of univer- sals, and from these again others ad infinitum universalissima, the art of which, should it require to be practised, which rarely happens, may easily be gathered from what has been laid down.” ’ Napier’s second book, entitled “ of positive or cossic algebra,” commences, like the last, with definitions, divisions, and a vocabulary. He defines the positive part of algebra to be that which “ discloses, by means of feigned suppositions, a true quantity and true num- ber sought.” He defines suppositions or positions, “ certain fictitious symbols attached to unity, which, in the place and on the part of quantities and numbers unknown, we add, subtract, multiply, and divide. ‘Positions and the symbols of positions are as various and dissimilar as the unknown quantities which the question embraces. Their figures and names are, ex. gr. 1 B, which is pronounced one first position ; 1 a, pronounced one a, or one second position ; 1 b, one b, or one third position, and so on through the rest of the alphabet.” ‘These symbols compose what our philosopher calls “ things first in order.” He then proceeds to deduce the successive orders [2. e. powers] in infinitum by the involu- ’ tion of these symbols, and illustrates his exposition by the following table : Numeri | Characteres et exem- | Characteres et exem- { Characteres et exem- ordinum. | pla ordinum prime | pla ordinumsecunde | pla ordinum tertia|&c- 0 positionis. positionis. positionis.

It is rich in de- finitions, and he leaves no step in his progress unexplained. He uses figures for the known quantities, the universal literal system having been introduced at a later period. We see from the preceding table and nomenclature, that the wnknown quantities he class- ed in positions, and called positives, or things, which last term is not strange in the history of algebra, the science having been called by the Italian authors Regola de la Cosa, or Rule of the thing, which is also the derivation of the term cossic. From the second chap- ter to the eighth inclusive, Napier proceeds, in his usual minute and symmetrical manner, through the whole arithmetic of the cossic art. In chapters ninth and tenth he enters upon the theory of equations, one of the most important and complicated departments of analytical science, and in which he is far before the algebra of the period when he com- posed this treatise. How little was it ever suspected that the algebraic triumphs of Vieta, Harriot, and Girard, whose principal works were not known to the world for many years after the date of this manuscript, were some of them actually in the possession of this retired and unpretending Scottish baron, though laid aside among his papers, and never known publickly till now! Professor Playfair, in his Dissertation, sketches the history of the slow progress of this branch of algebra, and shows that the genesis of equations first received a decided explication in the works of Harriot, not published till the year 1631. He adds, “ ‘Their slow progress arose from this, that they worked with an instrument, the use of which they did not fully comprehend, and em- ployed a language which expressed more than they were prepared to understand ; a lan- guage which, under the notion first of negative, and then of imaginary quantities, seemed to involve such mysteries as the accuracy of mathematical science must necessarily refuse to admit.” But early and rude as was the period in the history of algebra to which we must refer the composition of Napier’s manuscript, we find him treating these mysteri- ous quantities as if he had a perfect command of them, and looking forward with exul- tation to his future applications of such great algebraic secrets. Nothing can be more interesting in the whole history of his studies, than his opening chapters of that re- doubtable subject Equations. They prove beyond question that he was among the very first to understand that recondite subject; which he did so thoroughly as to com- pose a treatise, the fragment of which may be compared with any of the greatest that have succeeded him, from Harriot to Euler. Now this is very striking. The inter- nal evidence is irresistible that Napier composed his algebra before his arithmetic, and geometrical logistic. ‘The progress of his studies appears to have been in this order. Having mastered algebra he conceived the noble project of composing four books embra- cing every department of numerical science ; he returned accordingly to the simplest ele- ments, and with an extensive prospect and command of the vast field before him, he had digested his subject, and ‘ sett it orderlie doun,” nearly as far as his original books of al- SR 498 HISTORY OF THE gebra, and had even commenced a systematic reformation of the symbolical language of algebra, when the invention of Logarithms interrupted his original plan. This great in- vention, however, had, it seems, occurred to him before the year 1594, when Tycho got a hint of it from Napier’s friend Craig ; and, indeed, from his own expressions, we must date his conception of the Logarithms many years before their publication. His treatise ou Numbers, then, in which he betrays no idea either of Logarithms or Decimal fractions, must be referred to a very early period, and it is impossible that when he wrote it he could know any thing of the writings of Vieta. “ Most of Vieta’s algebraic works,” says Dr Hutton, “ were written about or before the year 1600, but some of them were not published till after his death, which happened in 1603.” And this is most material to observe that, “the two books de equationum recognitione et emendatione, which contain Vieta’s chief improvements in algebra, were not published till the year 1615 ;” indeed, his scattered works were only first collected into a volume thirty years after our philo- sopher’s death. But the historians of science are agreed that, although some important conquests were achieved in that department by Tartalea, Cardan, and a few others, the general theory of equations was only first opened by Vieta, who paved the way for Harriot and Des- cartes. Montucla says, ‘‘ The different transformations which may be adopted to give an equation a more commodious form, are, at least for the most part, the invention of M. Vieta, who taught the method in his book entitled De Emendatione Aiquationum. We there learn how to perform all the operations of arithmetic, addition, subtraction, multiplication, and division, upon the roots of equations. By means of that he causes the second term of an equation to disappear; an operation which at once resolves quadratic equations, and prepares the cubic. Itis thus, too, he causes the fractions to vanish which embarrass an equation, that he delivers it from irrationality when any of the terms are embarrassed thereby; all these things have been adopted by the modern analysts, and form what they call the preparation of equations; after these preliminaries M. Vieta passes to the resolution of equations of all degrees.” This is just the object of the two chapters on equations with which, unfortunately, our philosopher’s manuscript concludes. The first of them, being the 9th of the 2d book of his aglebra, is entitled “ of Equations and their Roots,” and the one following is “ of the general Preparation of Equations.” No more is extant; but in these chapters he refers to succeeding ones, as if already composed, and expressly mentions that, after laying down all the rules of preparation, he means to give the methods of resolution. 'Though none of these valuable lucubrations were ever pub- lished, and only a fragment has been saved, yet in the history of his own mind, and in estimating the honour he confers upon his country, the fact is most interesting. Euler, of whom those most capable to judge have said, ‘“ that he was indisputably the greatest analyst that has ever appeared,” concludes the work, by which I have all along tested Napier’s, with the theory of equations. So does our philosopher his, and here again the same comparison may be safely challenged. ‘ Even in the state in which he left his work, INVENTION OF LOGARITHMS. 499 among his loose papers, and not remodelled and fitted to the first books, as he obviously intended to have done, all that remains of his doctrine of equations is richer in tuition, more systematically arranged, and appears to lay the foundation for a more masterly exa- mination of the subject than the corresponding chapters of Euler’s finished work. This pretension is so high that, in order to justify it, I have given the two last chapters of the manuscript entire in the Appendix, and have translated them for the benefit of those who might not take the trouble to read algebra in Latin. In the translation, I have adhered as literally as possible to the original. Some of his terms, and of course his symbolical language, differ from that now in use; but he is so precise and explanatory that, with the aid of the vocabulary already quoted, it is easy for any one acquainted with the his- tory of algebra to follow him. ‘The learned will there find that he is not only anticipat- ing Vieta in what Montucla refers to that philosopher, and from whose merit, of course, Napier’s unpublished work cannot detract, but that he is evidently stretching beyond the triumphs of Vieta to those of Girard and Harriot. It is impossible to read his opening chapters of equations, and not admit that they indicate a maturity in the subject for which Vieta is held only to have paved the way. Girard is considered the first in whose work, published long after Napier’s death, the refined and difficult doctrine of imaginary quan- tities and roots assumes a place in science. Our philosopher clearly has this doctrine, and apparently a great command of the subject. The reduction of equations he calls expositio, and the root exponens. He states how various are those roots; that they are valida when prenoted with the sign +, and invalida with the sign —; in other words, po- sitive and negative roots. He also defines the nature of an impossible equation, with the view of preparing the way for his doctrine of imaginary roots; a doctrine which it is ob- vious he had profoundly considered ; indeed, he lays the foundation for it, as a great al- gebraic secret not then known, in his chapter of abundant and defective quantities which has been quoted. He also refers to roots of every description, capable of beg expres- sed by number or quantity, or both, or neither; clearly embracing all roots, rational and irrational, real, and imaginary ; and then he expressly adds, that “ these with their ex- amples shall be amply discussed in chapters 11, 12 and 13,”—the chapters which ought immediately to follow that with which the manuscript abruptly concludes. The terms he so frequently and fearlessly uses of quantities less than nothing, and impossible or ima- ginary quantities, all of which have been referred to Girard as their originator, indicate that command of the subject which was not to be daunted by the difficulty of naming such quantities, and that he was prepared to show how the phrases were justified in science. It is also very interesting to observe, that although he does not adopt, as Vieta did, letters for the known quantities, his notation is in some material circumstances be- yond that philosopher’s. Mr Babbage, in his History of Notation, observes, “ it is a curi- ous circumstance that the symbol which now represents equality was first used to denote subtraction, in which sense it was employed by Albert Girard, and that a word signify- ing equality was always used instead until the time of Harriot.” This sentence, it must 500 HISTORY OF THE be observed, overlooks the claim of Recorde, who, if he did not succeed in establishing the sign of equality, unquestionably proposed it, as I have elsewhere noticed. Napier, however, adopts it, and, with his usual precision, defines it in these words; “ betwixt the parts of an equation that are equal to each other a double line is interposed, which is the sign of equation (signum equationis); thus, 1 RB = 7, which is pronounced, one thing equal to seven.” ‘To Vieta is ascribed the vinculum in algebraic notation, which Girard changed to the parenthesis. ‘This, as is well known to algebraists, is used to denote the compound of binomial surds yielding what are termed roots universal. ‘The English algebraists, chiefly, use the vinculum, which is drawn above the compound thus, ,/ a + 6. Napier explains and uses this notation, with the simple variation of drawing the line un- der the compound. In the 12th chapter of his arithmetic of surds he lays down; “ to extract the square root of this quantity ./ Q 48 + / Q 28, prefix to this binomial (huic binomio ) the following radical sign ,/ Q, with a period after it thus, / Q. ,/ Q48+ ./ Q28,” &c. and in the 17th chapter of the same book he gives this example, after explaining the notation, “ the square root is extracted from this quantity 5 + ,/c2— / Q38—J/ Q2, by prefixing the sign of the root universal with a line drawn in this manner, /Q.5+ /c2—/Q.38—,/Q2.” &e. Accordingly, this vinculum will be found frequently used in his equations, and sometimes a vinculum withinavinculum. Yet even later than Vieta that convenient notation was not in constant use. Oughtred adopts the wu after / to denote universal, instead of what is called ‘* the vinculum of Vieta.” I can nowhere find in Napier the sign x of multiplication, which Oughtred introduced. In the pre- paration of equations our philosopher is far in advance of the date of his manuscript. ‘“¢ Harriot,” says Bossut, * was the first who thought of placing all the terms of an equa- tion on one side, and thus distinctly saw, what Vieta had only pointed out in a confused manner, that in every equation the coefficient of the second term is the sum of the roots taken with contrary signs,” &c. Butit will be observed that Napier had this mode of pre- paration, and made much of it.‘ If,” says he, “ you transpose all the terms of one side of an equation to the opposite side, the whole will be made equal to nothing, and this is called an equation to nothing,” &c. What I have thus imperfectly abstracted from this most interesting relic will enable the world to see that the Inventor of Logarithms was not a mere calculator who had made a lucky hit in a path where others were close behind him; but that had he only pub- lished his treatise on Logistic, without having invented the Logarithms, he would have tak- en the place of Vieta,—have anticipated the triumphs of Harriot—and, at a still earlier period, have placed Britain in the very highest ranks of those countries from which ana- lytical science has received its greatest impulses. It appears to me unquestionable that Napier composed his Arithmetic, and conse- quently his Algebra, before conceiving any of those mechanical inventions in aid of cal- culation, of which his own account has been given in the preceding memoirs. His 4 INVENTION OF LOGARITHMS. 501 Rabdologia and his Promptuarium would otherwise have been frequently and promi- nently referred to.* In the former of these inventions, so well: known under the name of Neper’s Bones, the philosopher’s object was to reduce the labour of multiplication and division to the less laborious operations of addition and subtraction,—to make the pri- matives do the work of the derivatives. From the moment he commanded the genealogy of numbers, this seems to have been his constant endeavour. ‘* Napier,” said poor Pin- kerton, ‘‘ was not a great inventor, he was only a useful abbreviator of a particular branch of the mathematics.” But it was the power of his mind that impelled him to this. The finest geniuses are they who have felt most intensely the trammels of calculation. Many a man passes for a great mathematician, because he is a huge computer. Hutton and Maseres were great calculators rather than great mathematicians, When their pages were full of figures and symbols they were happy ; and they took up the subject of Lo- garithms, con amore, from the very love of that labour to which the Logarithms were opposed. Archimedes and Napier were antt-calculators. But Napier alone, of all philo- sophers in all ages, made it the grand object of his life to obtain the power of calculation without its prolixity. At whatever period, therefore, our philosopher composed his minor works, they must be regarded with great interest, from the evidence they afford, that, with this object constantly before him, he left no department of numerical science not enriched by his most original genius. ‘They compose a chapter, and no mean one, of his universal system of numbers. Mr Herschel, in his History of Mathematics, has said, ‘ Napier, struck with the dif- ficulties which encumbered arithmetical computation of any length, and which various circumstances had about that time concurred to place in a very prominent light, after bestowing much fruitless labour on the invention of mechanical contrivances for multi- plication and division, rejected this plan, and struck on the happy idea of Logarithms.” Yet the great Wolff has devoted an elaborate chapter of his Llementa Matheseos to the “¢ Tamellas Neperianas, quarum ope multiplicationem ac divisionem facilius absolvere licet quam per abacum Pythagoricum.” ‘The great Leibnitz did not disdain such mechanical inventions, and has referred pointedly to Napier’s while praising his own in competition with the machine invented by Pascal. + It is interesting to regard our philosopher as * The only reference to his minor inventions which occurs in the manuscript tends to confirm this re- mark. In his chapter entitled “ Miscellaneous short methods of Multiplication and Division” this note is marked as an interpolation to a passage regarding short methods of multiplication, “ sive omnium facillime per ossa Rabdologie nostre,” clearly implying that he had not the method when he wrote his Arithmetic. Had Napier lived to finish his treatise on Logistic, it would have been the most splendid work of the kind in existence. His Mechanical Arithmetic, Logarithms, and Decimal Fractions, with all his improvements in notation would have been added to his system; and how much of that system would have been his own! +- © Jai encore eu le bonheur de produire une machine arithmetique infinement différente de celle de M. Pascal, puisque la mienne fait les grands multiplications et divisions en un moment, et sans additions ou soustractions auxiliares; au lieu que celle de M. Pascal, dont on parloit comme d’une 502 HISTORY OF THE the father of this school too,—a school whose labours are fruitless, just because the Lo- garithms have superseded their utility, unless, perhaps, we except that Leviathan of an abacus, so fearfully constructed ‘‘ that the machine can itself correct the errors which it may commit, and that the results of its calculations, when absolutely free from error, can be printed off without the aid of human hands, or the operation of human intelli- gence” (Brewster) ; and this Mr Babbage is inventing chiefly for the purpose of comput- ing Logarithms. Iam inclined to doubt the theory that Napier rejected Rabdologia, and then set himself to seek the Logarithms. From his letter to the Chancellor, a very different idea may be gathered. He appears to say that he contrived such artifices for the special benefit of those who might distrust the artificial numbers. ‘There occurs in the work, “* Tabulato anno Domini 1615,” an example, however, that may possibly have been added when he was preparing for the press this profound and elegant little volume, which we are sure Mr Herschel had never looked at when he slighted its con- tents. Independently of other merits, it is hallowed by the fact, of containing perhaps the earliest chapter upon decimal fractions ever composed in Britain, and under the per- fect notation which Napier was the first to adopt. It is singular, that, after having proceeded so far in the path of numbers, our philoso- pher achieved his greatest conquest, which lay directly in that very path, and not far before him, by a different and an eccentric route, belonging to an opposite branch of science. The Logarithms should have been the offspring of his Arithmetic and his Algebra. He made them the offspring of his Geometry and his Arithmetic. Instead of prosecuting the arithmetic of powers and exponents, he turned to the geometry of his fluxions and his fluents,—terms unknown till then,—a method strange and startling to the philosophers of his times,—distrusted in another age when once again it reappeared in the hands of Newton,—yet successively productive of the Logarithms and the Calculus. The fact is, that Napier was as fearless and as powerful in geometry as he was in logis- tic, which accounts for the method he adopted. _ Who but himself, with the whole sys- tem of arithmetic and algebra brought under his control, would, in aid of calculation, have set to work with a flowing point! His fluxionary method was characteristic of the same unfettered genius that commanded the scale on either side of zero, and could even see that quantities, ‘ impossibiles et nihil significantes,” though revolting in language, were precious in calculation. The application of arithmetic to geometry created the science of trigonometry. Napier made the application anew, and revolutionized that science, not merely in its tables, but in its rules. As a geometrician, therefore, he may almost be said to have been more successful than as an arithmetician, for the Logarithms themselves were chose merveilleuse, et non pas sans raison, n’etoit proprement que pour les additions et soustractions, qu’on pouvoit combiner avec les batons de Neper, comme a fait depuis Mr Moreland.”— Lezbnitii Opera, Tome vi. p. 248. INVENTION OF LOGARITHMS. 503 a geometrical conquest. ‘ As a geometrician,” says Playfair, “‘ Napier has left behind him a noble monument in the two trigonometrical theorems which are known by his name, and which appear first to have been communicated in writing to Cavalieri, who has men- tioned them with great eulogy ; they are theorems not a little difficult, and of much use, as being particularly adapted to logarithmic calculation.” * The rules alluded to, generally termed Napier’s Analogies, are well known to mathema- ticians. One of his demonstrations is characterized by peculiar elegance and originality. In the optical illustration, we may observe an indication of those habits and acquisitions, which led him to revive the lost catoptrics of Archimedes, whose history is given in the memoirs. I shall adopt here the abridgement of it by Dr Minto, referring the reader to the Canon Mirificus for the original. ** Let a plane MN touch the sphere ADP at the point A, the extremity of its diame- ter PA. Upon the surface of the sphere let there be described the triangle Ady acute in y, or AX€ obtuse in. Let the sine Ad and the base Ay or A® be produced to the point P. With the pole 4 and distance ’y or its equal 1¢ let the small circle of the sphere Cyz6 intersecting AP in « and AA in 6 be described: and from A let the arc Aw be drawn perpendicular to A¢y. Ay is the sum of the segments of the base and A¢ their difference. A: is the sum of the sides and Aé their difference. Let there be supposed a luminous point in P: The shadows, A, d, and ¢, of the points A, € and y, upon the plane MN, are in the same straight line, because the points A, ¢, y, and P are in the same circular plane: also the shadow A, d, and e, of A, 6, and <, upon the plane MN, are in the same straight line, because A, 6, <, and P, are in the same circular plane. Since PA is perpendicular to the plane MN, the plane triangles PAc, PA’, PAe, and PAd, are rectangular in A: therefore, to the radius PA, the straight lines Ac, Ad, Ae, and Ad, are the tangents of the angles APe or APy, APO or APc, APe or APs, and APd or AP? respectively. * Professor Powell has also said (Historical View, &c. p. 194,) that Napier, before he published his trigonometrical theorems, “ communicated them in manuscript to Cavalieri, who mentions them with high commendation.” There is, however, a strange mistake here. Napier never corresponded with Cavalieri. That great philosopher was the first Italian commentator upon the Logarithms, but he was only born in the year 1598, as Professor Playfair himself tells us, and as Professor Powell of course re- peats. Consequently, when Napier had his rules in manuscript, Cavalieri was an infant, or, at least, a child. Besides, Bonaventura Cavalieri was a Papist! a friar of the order of the Jesuati of St Jerome! And the old Scotch baron, who, God bless him, never communicated the scrape of a pen to any philo- sopher, would not have sent his theorems to one who was a jesuitical friar. Playfair quotes Wallis as his authority; but the passage has been misunderstood. Wallis ( Opera Math. Tom. ii. p. 875,) says, “ Proportiones sequentes duas Cavalierius acceptas refert Nepero ; nec immerito eas dicit alte indagi-- nis? But it is manifest that this means no more than that the Italian philosopher acknowledged that science was indebted to Napier for those rules, which, he adds, evince a lofty genius. The same is also apparent in Cavalieri’s great work on Logarithms, of which the editions are dated 1632 and 1643. This philosopher has the honour of being the first who established the Logarithms in Italy. 504 HISTORY OF THE But these angles, being at the circumference of the sphere, have for their measures the halves of the arcs intercepted by their sides: therefore Ac, Ad, Ae, and Ad, are the tan- gents of the halves of Ay, Aé, Az, and Aé respectively. Now, by optics, the shadow of any circle, described on the surface of the sphere, produced by rays from a luminous point situated in any point of that surface excepting the circumference of the circle, forms a circle on the plane perpendicular to the diameter at whose extremity the luminous point is placed: therefore the points c, J, e, and d, are in the circumference of a circle : there- fore Ac x AJ = Ae X Ad. Q. E. D.” GC M. MULL MLE But it is not merely by his Analogies that our philosopher is distinguished in trigono- metry. The same object that he constantly pursued in numbers, he struggled to attain in his geometrical path. He determined to enable the student, with the least retentive memory, to carry as it were the whole science of trigonometry in his head, and he actu- ally succeeded. ‘There is not a modern work upon the subject in which Napier’s rule of the circular parts is not the relief of study, and the theme of praise. If we turn to the most distinguished elementary works we find it said, “ the rule of the Circular Parts in- vented by Napier, is of great use in spherical trigonometry, by reducing all the theorems employed in the solution of right-angled triangles to two. ‘These two are not new proposi- tions, but are merely enunciations which, by help of a particular arrangement and classifi- cation of the parts of a triangle, include all the six propositions with their corollaries ; they are perhaps the happiest example of artificial memory that is known.” ( Playfair’s Ele- ments). If we turn to the most distinguished philosophical treatises, we find, “ these forms are not easily remembered, and, therefore, an artificial memory has been sup- plied to the student and computist, by rules known by the title of Napier’s Rules for Cir- cular Parts ; and in the whole compass of mathematical science, there cannot be found, per- haps, rules which more completely attain that which is the proper object of rules, facility and INVENTION OF LOGARITHMS. 505 brevity of computation.” —( Woodhouse, of Cambridge.) If we turn to the great histo- rians of science the same eulogy is to be met with. Wallis expounds the rule, and adds, ** this, Napier excogitated for the relief of memory, and Cavallerius, Ursinus, Vlaccus, and our own Gellibrand, Oughtred, Norwood, Ward and Wing, have applied it to va- rious cases.” Montucla observes, ‘* it would appear that Napier’s views always tended to the simplification of practice ; among his inventions, one for the resolution of spherical rectangular triangles is especially remarkable, and in the judgment of all acquainted with it extremely ingenious and convenient; indeed those versant in spherical trigonometry know that sixteen cases in spherical rectangular triangles may be proposed, and of these there are ten or twelve so difficult that authors who have written on the subject have been obliged to construct a table to consult for the relief of memory; Napier’s rule reduces all these cases to a single rule, composed of two parts, whose elegant form is particularly apt to impress itself profoundly on the memory; hence the English trigonometrists generally adopt it, and I cannot conceal my surprise at scarcely finding a trace of it in various French and Continental treatises upon trigonometry, published since that epoch; M. Wolff, however, has felt the merit of it, and taught it in his Hlementa Matheseos Uni- versalis.” ; No wonder, then, that, with such geometrical powers of invention, our philosopher reached the Logarithms through that path. But it would, indeed, have been wonderful, if, after having done so, he had not, with all his command of numbers, have immediately perceived that the transcendental system he had created was not fitted for ordinary calcu- lation, and if he could not have supplied the desideratum. ‘There were various practical inconveniences in his system which it was impossible he could fail to perceive. Above all it was inconvenient and unsuitable, for common operations, to have a system of Loga- rithms whose fundamental progression was not accommodated to the root, or base, of the arithmetical scale in use. This fact could escape no calculator the moment he attempted to work with the new-born power, and to doubt the fact which Napier asserts, and which Briggs never upon any occasion hesitated to admit, namely, that he (the object of whose lite was to increase the power, by simplifying the means of calculation,) had himself ob- served and provided against that inconvenience, is just as absurd as we have seen that it is unjust. He had only to return from his geometrical flight,—which, however, had brought out the lofty system that is the parent of all others,—to his simplest arithmetical considerations, in order, as he says himself, “ to set out such Logarithms as shall make those numbers to fall upon decimal numbers, such as 100,000,000, 200,000,000, 300,000,000, &c. which are easy to be added or abated to or from any other number.” It was the practical inconvenience, and not the algorithm of powers and exponents, that led to this change ; a change which itslf first opened the doctrine of fractional exponents. * * 1000 equals 10 raised to the third power ; 10,000 equals 10, to the fourth power ; 3 and 4 respec- tively are the logarithms of those numbers; and, taken as powers and exponents, are written thus, 10° 10%. But what is the logarithm of 2000? which, in the modern view of the subject, is the same as 358 506 HISTORY OF THE There never was before, or has been since, or can be again, such a destiny in numbers. What could have compensated his country for the suppression of his system of algebra but that he forsook it to invent the Logarithms? Who would not have advised him to turn neither to the right hand nor to the left from that analytical career in which he had triumphed so far? A step or two in notation,—and he had systematically com- menced to clear that path,—would have opened to him the arithmetic of exponents,— the Logarithms,—the Binomial Theorem! all of which, from a mind such as his analy- tical treatise displays, we may safely say nothing but a rude notation veiled. But he was not satisfied with the powerful machinery of integers and fractions, abundant, defective, and imaginary quantities, uninomes and plurinomes, and all the play of radical and cossic signs that he had reduced to obedience. ‘The stars were becoming too many for Tycho and Kepler,—so he determined to attack the numeral scale through another medium. ‘Then what a result—what an episode in his analytical labours—what a corollary to his great de- sien! Having surveyed, and mastered, and nearly digested the whole field of Logistic, so that his unfinished manuscript may compete with Euler’s finished production,—having con- quered computation and attacked notation, the ARCHIMEDES OF THE NORTH paused, not to rest, but to seek another path of conquest. In that very departure from his alge- braic career he brought out, as it were by a single blow, two great sections of the Arabic scale, which had been latent till then, and caused an important end of the exponential system to become the means of developing that very doctrine. Then how thoroughly was the object of his constant study fulfilled in the Logarithms! ‘ By their means it is that numbers almost infinite, and such as are otherwise impracticable, are managed with ease and expedition. By their assistance the mariner steers his vessel—the geometrician investigates the nature of the higher curves—the astronomer determines the places of the stars—the philosopher accounts for other phenomena of nature—and lastly, the usurer computes the interest of his money.”—(Kevll.) But in what age, or in what department of science, can we limit the impulse which the crowning success of Napier’s ruling propensity created? ‘ The quadrature of the hyperbola,” says another elegant and distinguished phi- losopher, ‘ was now no longer a matter of mere speculative curiosity. Practical utility was become deeply interested in the investigation by a discovery which the beginning of the seventeenth century produced, but which we deferred speaking of that we might connect it with its proper link in the great chain.”—‘“ The invention of Logarithms was a most invaluable present to the calculator, but its influence extended still wider. Gregory St Vincent in 1647 had demonstrated the grand property of the hyperbola which connects its area with the logarithmic function; and Mercator, pursuing this subject at length in his Logarithmotechnia (1667,) distinctly reduced the construction of logarithmic tables to ask, what power of 10 is 2000? It must be represented by three integers and a decimal fraction thus, 3.301. It is obvious, therefore, how the common logarithms are connected with the doctrine of frac- tional exponents. So, reversing Dr Hutton’s dictum, we may say, that the invention of Logarithms led to the algorithm of powers and exponents,—the very path that would have led to them. INVENTION OF LOGARITHMS. 507 to the quadrature of hyperbolic spaces. The unsuccessful attempts of Wallis now came under his contemplation, and what that geometer could not accomplish, Mercator effected by the simple but happy idea of continuing the division of the numerator by the deno- minator to infinity, as in the decimal arithmetic, and applying the method of Wallis to the series of positive powers which results. The first general quadrature of the hyperbola was thus obtained at the same time that the regular developement of a function in series was now distinctly exhibited.”—‘* Such were the grounds upon which Newton was to raise the mighty fabric of his mathematical discoveries. Previous to the publication of Mercator’s series, the perusal of Wallis’ work, as himself relates, had led him to con- sider how the general or indefinite values had afforded that writer his quadrature of the whole circle. ‘This was a work of comparatively greater facility than that undertaken by Wallis, and his undertaking was accordingly successful. It immediately struck him that the same method of interpolation might be applied to the ordinates as to the areas, and, by pursuing this idea, he arrived at his Binomial Theorem, which proved the key to the whole doctrine of series.” —( Herschel.) I have done my best to illustrate the domestic history—the Christian character—the philosophical power of Napier; and, however rudely the task may have been performed, the world has now a better basis for his eulogy than, perhaps, England’s historian was aware of when he called him “ the person to whom the title of a Grear Man is more justly due than to any other whom his country ever produced.” ui eg?

NOTES AND REFERENCES. Nore A. Tuart the earliest ancestor of the philosopher’s, in lineal male ascent, who can be dis- tinctly traced, was the first Napier of Merchiston, is proved by an entry in the great Chamberlain Rolls of Scotland, preserved in the Register-House, from which it appears that ‘‘ Alexander Napare” acquired the lands of Nether-Merchiston by wadset from James I. sometime before the year 1438. The genealogical document transmitted by the first Lord Napier to Sir William Segar is printed in Hutchins’ Dorsetshire, ii. 48, where the genealogical history of the distinguished English cadets of Merchiston, Na- piers of Luton-hoo and Napiers of Morecritchill are given. This author says, “ the Napiers of Scotland are also extinct, though the barony of Merchiston still exists in another family, their descendants.” ‘This is very inaccurate. The Lord Napier of Mer- chiston is the lineal descendant of the philosopher, and represents him in his right to the dormant Earldom of Levenax, although he is not lineal heir-male of Napier. But the philosopher is represented in the direct male line by Sir William Milliken Napier of Napier and Milliken, Bart. who has many sons. William Napier, Esq. of Blackstone, of whose hospitable house we wish the same could be said, is also a lineal male descen- dant of the philosopher’s. Besides, are the Generals, and Colonels, and Majors, and Captains Napier, distinguished in the service of their country, and who have scattered ‘‘ Neper’s bones” by sea and land in the shape of their own limbs, to be forgotten as scions of Merchiston? This note was intended to record the Scottish Napiers; but the clan and their gallant deeds are so numerous that I must sum them up in one word, Carlos da Ponza, Count Cape St Vincent, who, alas! has no'son.

The philosopher’s reply to the queries of Sir John Skene are, like every thing he composed, characterized by consummate skill and the most unpretending simplicity. The reader will find them in Skene’s treatise De Verborum Significatione, voce Perticata. Note E. The peerage writers have generally recorded that the second wife of the philosopher’s father was Elizabeth Mowbray, daughter of Mowbray of Barnbougall. Mr Wood supposed this lady to have been the daughter of Robert Mowbray; but dates and facts have led me to the conclusion that she was the daughter of John Mowbray, Ro- bert’s son. Sir Archibald Napier was married to this lady about the year 157], at which period the laird of Barnbougall was John. In the register of obligations, pre- served in the Register House, there is a marriage-contract, dated at Barnbougall, 6th August 1572, ** betwixt honarabill persones, Johne Moubray of Barnebougall and Agnes Moubray, his dochter, and Maister Robert Creychton of Eliok,” &c. John Mowbray had a daughter Elizabeth, who is named ina deed, dated 2d February 1585-6, dividing a pro- vision of 1500 merks among his family. Of this sum, 1460 merks are allotted to John Mowbray’s daughter Marion, and only 20 to Elizabeth, her sister ; probably because she was sufficiently provided for by marriage to Sir Archibald Napier. Agnes was dead at this time, as appears by a previous deed, dated 14th September 1575. ‘The other sisters were with Queen Mary. The children of John Mowbray were, through their mother, cousins to Sir Archibald Napier. Barbara and Gilles Mowbray were the companions of Queen Mary in her captivity. In “la mort de la Royne d’Escosse,” which records the se- verity of the English government towards the domestics of Mary after her execution, this sentence occurs; ‘‘ le Baron de Barnestrudgal, gentilhomme Escossois, qui avoit deux de ses filles en prison, vint 4 Londres, ou ayant commandement du Roy d’Escosse de parler pour les serviteurs de sa mere, poursuyuit leur deliverance.” Mary’s fu- neral took place immediately afterwards, and “ Madamoyselle Barbe Maubray” and ‘“¢ Gilles Maubray” are recorded among “ Jes femmes de la Royne d’Escosse,” who walked in the pageantry. Barbara Mowbray’s tomb at Antwerp records her fidelity to Queen Mary, and the fact that she was the daughter of John Mowbray, a Scottish baron. There can be no doubt that Barnestrudgal is a corruption of Barnbougall; and that Bar- bara and Gilles were the two daughters whose release from prison the venerable father- in-law of Sir Archibald Napier travelled to procure.

IreM, to schew to the saide Lorde Duc of [sic] the behalve of the King, that his en- tent of the sending of his last ambaxat was for to approve and renew the ald confedera- tions and appointmentis made of befor betwix baith thare predecessours, and to conclude apon a certane article of new, tusching the sending of certane men of war upon the expenss of the party requerand, as is mar at lenth contenit in the endenture made betwix baith the commissionars thareuppoun, and evar to haue hade the said confedarations of mar strenth and effect than thai war of befor than of less, nochtwithstanding the Kingis am- bassiat, quether reklessly or of necligence he wait nocht, excedit the bounds of thare instructionis, and consentit to ane inconvenient, and concludit tharuppoun ; that is to say, that his said cousing the Duc exceppit in his band the King of Ingland, and becaus the King has nane uthir Prince that makis war apon him, he couth nocht fynde the way to appruve nor conferme the said appomtmentis ; and tharefor, for his part, he has left owt the exceptioun of the King of Denmark, his gude-fader, likeas he has schewin now of late mar at lenth to the ambaxators of the said Lorde Ducis: For the quhilk causs, and to the effect and entent that the King desirs the tendernes and favours of his said cousing, and to pless him sa far as he gudely may with his honour, baith becaus of nere- nes of blude and the repar of his liegs and merchands in his lordschippis and tounys in thai partis, he has send to him his treue and famuliar knicht, Schir Alexander Napare, with his letter under his Great Sele, in effect comprehendand baith the auld confedera- tioun and new in all points and articlis, the exceptioun of the said King of England alenarly left out for the party of the said Lorde Duc, and for the party of the King, the excepping of his gude-fader of Denmark richt swa left owt.

Irem, to schaw to the said Lorde Duc, and remember how that now of late his am- baxat has bene at the King, desiring ane new abstinence of war and trewis betwix him and the King of Ingland for twa zeris, under certane forme and effect, likeas was con- 4 APPENDIX. 513 tenit in thare instructonis ; and, nochtwithstanding that trewis was taken for lang termez and mony zeris of befor betwix baith the said princes, and that the Kingis lieges, baith be sey and be land, has sustenit gret skaith and dampnage unredressit, and letters of promitt of King Edward and uthers under him bundyn tharfor ; nevertheless, becaus it was understanden be the king that the said abstinence and trewis was desirit be the said Lorde Duc, his cousing, for the gude ese and support of him, yet tharefor the King, his cousing, consentit and aggreit thareto at the emplesance of him, the quhilk he wald nocht have done be na manner of way at the instance of the King of Ingland, con- sidering that he and his people remanys plantwiss on him, and Inglismen unredressit. Irem, to schaw to the said Lorde Duc, that sen at the emplesance of him his cousing, the King of Scotland has consentit and taken sic trewis with King Edward for the termez desere be him, that tharefor he write his autentik letters with personis of fame and auctorite to the said King Edward, to mak him redress incontinent the bargh broken at Balmburgh, and the laif of the attemptats that ware adiugit to be redres- sit the last diet haldin at the Newcastel, and sensyne, for thair part, like as the King here is reddy to mak redress for his part; and that he certify King Edward in his said letters, that without redres be made the peple of his realme that ar herijt, hurt, and grevit, cannocht kepe pece in case trewis be never sa sikker bundyn.

Irem, into the matter of Gelrill, the said Schir Alexander Naper sal schaw, in oure Sourane Lordi’s name, to his cousing the Duc of Burgunze, how his grant-schir the Duc of Gelrill, quham God assoilze, wrate til him of late how that his son had cruelly put handis til his person, and takin him and put him in preson, and demainit him, as is wele knawin ; for the quhilk his said son, nor nane that mycht cum of him, mycht never apon law succede til his heritage ; for the quhilk, sen our Sourane Lord was his eldest doch- ter son, he exhortit and requirit him that he wald cum in the cuntrie, or send ane of his brethir, and he suld, with the aviss of nebles and baronis of his land, put him in the full possessioune of his said Duchery, sen he knew him nerrest and maist lachfull heretar til him. And now sen the said Duc is decessit, oure Sourane Lord, quhilk be the informatione of his foresaid grant-schir traistand to have full richt to the succession of the same, will nocht labour na put his hand to the said matter withoute counsale and aviss of his said cousing, the Duc of Burgunze, traisting verraly to have throu him supportatione, aide, and supplie in the said matter, and in the recovering of his richt, as he that is als ner of blude til him as ony uther that pretendis to have interess thairto, and sal be mair thank- full till him, baith in the demeinning of that matter and in al utheris, than ony utheris.

[ The Philosopher's Theory of Equations literally translated from the unpublished Latin Manuscript. | Cuap. 9.—Or Equations anD THEIR Exponents. 1. Equation is the collation of the uncertain values of positives [the unknown quanti- ties| with others of equal value, from which the value of the position is demanded. Thus, if for the number or quantity sought any one should place 1 B ignorant of its value, and then, from the hypothesis of the question, should find 3 & equal to 21, thus comparing three things with their equals 21, that collation of equality is termed @quatio ; and from it is inferred, that the value of one thing, or one position, is 7. 2. Betwixt the parts of an equation that are equal to each other a double line is inter- posed, which is the sign of equation, (signum equationis ;) thus 3 R = 7, which is pro- nounced, one thing equal to seven. 3. Of equations, some are only of one position, others of more; thus, as an instance of one position, 1aQ + 3a= 10; of more positions, 2Q—la=6. 4, Again, of equations, some are rude, and may be reduced to lesser terms, more per- spicuous and succinct ; others are called most perfect, which are as perspicuous and suc- cinct as possible. Thus, 3 = 21 is a rude equation, because it may be reduced into the most perfect form, namely, 1K =7. So 5aQ= 20 is a rude equation, because it can be reduced into a more perfect one, namely, laQ=4; but laQ= 4 is also a rude equation, because it may be reduced to one even of the most perfect form, namely, 1 a= 2; an art of which I shall treat hereafter. So 12Q+3a=6 is a rude equation, because it can be reduced into the more perfect one, 4Q+la= 2. 5. Again, of equations, some are simple, some quadrate, some cubic, and some higher. Those are called simple which consist of no more than two orders. Thus, 3B = 27, or 1BR=9; so 56Q= 20, are called simple equations. 6. Of simple equations, some are real, which are things equal to number ; others are radical, which are the equation of quadrates, cubics, or any of the higher orders, to num- ber. Thus, 3R=21, or 1K=7; alsola=3; so2R=,/ Q3—1 are real equations ; but 2Q = 8, also 3C = 24; also laSs= J CQ, &c. are radical equations. 7. That is a quadratic equation which consists of three proportional orders, thus, 2Q43B=4, or 83R=2 Q—4; also laQC— 10=3aQ; also 12—/QIB=1B8. 8. That is a cubic equation which consists of four proportional orders, thus 1 C—9Q — 24— 26B; also 1 C + 0Q—2R=4; this also, laQC—2aQ=4, is a cubic equa- tion, because, (according to our fourth proposition, c. 6,) collected in this manner, 1aQC+0aQQ—2aQ=4, it consists of four orders. 9, A quadrati-quadratical equation consists of five, a supersolid of six, a quadrati-cubi- cal of seven proportional orders, and so on of all the higher orders in infinitum ; thus 2QQ— 28C + 142 Q = 308 K — 240, is a quadrati-quadratical equation; 14 Q Ss — 516 APPENDIX. 4b QQQ + 16QC—3)Q Q— 10 Q = 121s a supersolid equation; 1laQC—3aSs +2aQQ—6aC+ laQ=1la+6, isa quadrati-cubical equation. 10. An illusive equation (2/usiva) is that which asserts an impossibility ; and if any one demands an impossibility in an illusive equation, his answer falls; thus 1 B =3 Bis an illusive equation, seeing it is impossible that any thing can be equal to the triple of itself; also 1 Q = 4B — 5 is an illusive equation, seeing that no quadrate can equal four things, or its roots, minus five ; as will be made manifest hereafter. 11. Exposition (ezpositio) is the reduction of a rude equation to the most perfect and real equation, and that part of the real equation which is equal to one thing is called the exponent (exponens ), and solves the question; thus, when this rude equation 3B = 21, is reduced to this most perfect 1B =7, the exponent of either equation will be 7, be- cause that is equal to one thing, namely, to 1B. Again, this rude equation 5 Q = 20 is reduced to this more perfect one 1Q — 4; then to this most perfect and real equation 1B=2; now the work of reduction is called exposition, and 2 the exponent, because it is equal to one thing. I shall afterwards teach how the exponent solves the question. 12. Every equation, except an illusive one, has at least one exponent, valid or invalid. I shall teach this hereafter ; at present it is sufficient to have premised so much. 13. Valid exponents are those which placed by themselves are noted with this sign +, and are always greater than nothing; but invalid exponents are those which placed by themselves are noted with this sign —, and these are less than nothing, (minora sunt nihilo) ; thus, in this equation 1 B. = 7, seven is a valid exponent, because (as by C. 6, Prop. 1, Lib. 1,) it is understood to be noted with the copula +; but in this real equa- tion 1 = —7, by parity of reasoning the exponent is termed invalid, because it is noted with the copula —, thus — 7, and is less than nothing. 14. Of exponents, some are capable of being expressed entirely by a single number, others again entirely by a single quantity ; some can only be expressed in a single num- ber, some only in a single quantity ; some partly one way and partly the other, some in neither way. These, with their examples, shall be amply discussed in their order in chapters 11;12;tand 13. 15. Every portion of an equation, subject to one leading sign, is called a term (minzma,) whatever number of signs and terms there may be; the leading and predominant sign is called the ductriz, and the rest are called intermedie ; thus in this equation 1C—3 + ,/ Q2 +ioet — /Q.6+4+ ,Q1B =0, in which | Cis called a term, and + its ductrix; 3R—4 so 3 is called a term, and — its ductrix ; so ,/ Q 2 is a term, and + its ductrix ; so TOL is a term, and + its ductrix, because its power extends throughout the whole fraction ; but the other signs of this fraction are called intermediates; so / Q.6 + ./ Q1B is called a term, and the sign — its ductrix, because its power extends throughout the aggregate value of the whole universal root ; the remaining sign + is called intermediate. ~y APPENDIX. 5] ~ Cuap. 10.—Or THE GENERAL PREPARATION OF EQuations. 1. Preparation is the reduction of rude equations to more perfect ones, which are afterwards reduced to the most perfect real equations by exposition ; thus 5 a Q = 20 is first prepared, and becomes 1 a Q = 4, then it is expounded 1 a = 2; the modes of pre- paration shall now be laid down; the modes of reducing shall afterwards appear. 2. Rude equations are prepared and made conspicuous in five ways; by ¢ransposition, abbreviation, dimsion, multiplication, and extraction. Of these modes the rules and examples follow. 3. If you transfer a term from one part of an equation to the opposite, and prefix the op- posite sign as ductrix, the parts are equal, and this is called transposition : as thus in this equation 4 R — 6 = 5 — 20, if — 20 be transposed from the posterior to the prior part of the equation, and the sign changed in this form, 41. —6 + 20 = 5B; again, transpose 4 B, and you have — 4 B, in this form — 6 + 20 = 5B — 4B; so of this equation 1Q— / Q.3 Q— 2= 3a, transpose — ,/ Q. 3 Q — 2, it becomes + / Q.3 Q— 2 inthis form, 1Q=3a+ /Q.3Q—2; and again, transpose 3a, that gives —3ain this form, + Q—3a=VJ/ Q.3 Q—2, and the opposite parts are equal as before. 4, If (as premised) you transpose all the terms of one side of an equation to the op- posite side, the whole compound will be made equal to nothing, and this is called an equation to nothing ; and, by the 4th prop. 2 c. of this book, ought to be abbreviated : thus, in the above example 4 RB — 6 = 5 B& — 20, transpose 5 B — 20, and you have — 5 & + 20 in this form, 4 RB — 6 — 5} + 20= 0, which abbreviated, becomes — 1 RB, + 14 = 0, and is an equation to nothing; so, in the equation 1Q—/Q.3Q—2= 3a, transpose the left side to the right, and you have 0 = —1Q+J/Q.3Q—2+4 34, which is also an equation to nothing. 5. If the highest unknown quantity have the sign — in front, convert all the ductrices of all the terms, and a more perspicuous equation will be produced; thus, to take the above example, if —1. + 14= 0, consequently + 1R—14= 0; so—1 Q +3a+ /Q. 3Q — 2= 0 becomes 1Q — 8a— ¥ Q.83Q—2= 0; so—1L BR—14 oo =" 0» be- 32 comes 1R + Le YO ieee 0. 6. If you divide all the unknown quantities of the highest order by unity signed with the positive and radical signs of the same order, and then divide the whole equation by the quotient, a perspicuous equation will arise, having the highest order signed with unity. Thus, in the equation 2C—8Q+ 6B = 0, divide the unknown quantity of the highest order, namely, 2 C by 1 C, the quotient is 2; then divide the whole equation by 2, and it becomes 1 C—4Q+ 3B = 0; so, in this equation 3K — y Q2 Q— 6 = 0, the un- known quantities of the highest orders are 3B — / Q 2 Q, which, by 5th prop. c. 4 of this book, are of the same order of power, and their order is of things ; divide, then, 3BR— y Q2Q by 1B, or (which is the same thing) by / Q1Q and the quotient is 3— JQ 2; by this pecan, nae to 2 prop. c. 11, lib. 1, divide the whole equa- tion and you have 1— 3 —*-;—= 0, which, athough it be a fraction, is more & 518 APPENDIX. perspicuous than before, in so far as the sign Q is removed ; so, to give a third ex- ample, 1Ra-+1a+1BR—31=0, from which, if you wish to expunge and delete the mixed sign, namely, 1 B a, divide 1 Ra+ 1a, by la,or 1Ra+I1RB, by 1 B, (which- ever you wish to receive in the place of the highest order ;) for example’s sake, Jet 1 BR be taken; divide, then, 1 Ra +1 per 1 B, the quotient will be 1a + 1, by which di- vide the whole equation 1Ra+ 1B + 1a—31=0, and the equation becomes 1R + 1 a = 0, which, though a fraction, is more perspicuous than before, in so far as that the mixed sign, which previously was obscure, is removed. 7. If the lowest order of an equation be an unknown quantity, then divide the whole equation by unity signed with the sign of the lowest order, and there arises a perspicuous equation, having an absolute number in the ‘place of the lowest order; thus, divide 1 C —4Q+3K=0, by unity of the lowest order, namely, by 1 B, and it becomes 1 Q— 4BRB+38—0; s083Q—,/ Q2BR=0 divide by / Q 1B, and this equation is obtained, /Q9C— JV Q2= 0, of which the last series is always number. 8. If any particles of an equation be true fractions, multiply the whole equation by their denominators, and there will be produced an integral equation more perspicuous; thus, s 6BR—8 : 5 : : in this equation fopoat 2 = 0, there is a true fraction, though abbreviable; multiply then the whole equation by the denominator 1C—3 Band you have2C + 12R— 8 Q=0; so, multiply this equation 1Q sues a = 0 by 3, and you have, in the first place, 3Q4+2BR— se 0; multiply this again by 75, and you have 225Q + 150 B — 264= 0, which are integral equations freed of fractions. 9. If there be in an equation a single root universal, separate it from the rest of the equation, (3d prop.) then multiply each side of the equation together as often as the sign universal denotes, and there will be produced a more perspicuous equation, for it will have no universal signs; thus2Q+3R— ,/Q.12C + 4QQ 4+ 18=— 0, first, by trans- position, becomes 2 Q 4+ 3R =,/Q.12C 4+ 4QQ-+ 18; then let the sides be squared, be- cause the sign universal is ,/ Q.and they become4QQ + 12C+9Q=12C+4QQ + 18; and, consequently, being transposed and abbreviated, become 1Q —2: To give ano- ther example; /C.2RK—6=83B8 the sides being cubically multiplied, become 2B — 6 = 27 C; otherwise, 2 R — 27 C—6=0. 10. If an equation consist of two roots universal similarly radicated, without any other terms, let them be separated by transposition, and multiplied together as often as the sign universal denotes ; and a perspicuous equation will be produced, free of roots univer- sal: thus let /Q.2B 4 5—/Q.83BR—4=0 be separated, and they become yQ.2B 4+5= /Q.3B— 4, which quadratically multiplied become 2B + 5= 3B — 4, and, by transposition and abbreviation, 1 B. —9 = 0. 11. If an equation consist only of two roots universal, dissimilarly radicated, let the universals be separated, and let each side be multiplied together, according to the quality of each sign of the dissimilar universals, and a perspicuous equation, free of universals, APPENDIX. 519 will come out; thus, let y Ss.3Q+6—/Q.2B—3=0 be first separated by transposition in this manner, ,/ Ss.3Q + 6=,/Q.2BR—=83; then let the sides be quadrati-supersolide multiplied together, and they become 32 Ss—240 QQ + 720C —1080Q+810K— 243 —9QQ + 36Q + 36, which transposed and abbreviated become 32 Ss — 249 QQ + 720 C— 1116 Q + 810 BR — 279 — 0. 12. If there be two roots universal squared with other simple quantities or uninomes in an equation, separate both the universals with their signs from the rest, and multiply quadratically the two sides together, and an equation comes out, consisting of only one root universal, which also may be removed by prop. 9 of this chapter: thus, if this equa- tion} + J Q.484+1BRB—1Q+4BR—VQ.79— ¢ Q =O, be transposed in this manner, / Q.79—#Q—/Q.48/+1B—1Q=3B + f, then each side being squared become 127 1 + 1B —12?Q— /Q. 15247 + 316 R— 4602 Q— 7 C4 3QQ =4iQ+4%+4; transpose and abbreviate this, and it becomes / Q. 15247 + 316 B — 4603 Q— 8C + 3QQ= 127 + } R—2 Q, which finally, by prop. 9, become 1QQ+4+ 1C— 47 Q— 189B + 892 = 0. 13. If an equation consist of three roots universal squared, without any other terms, let the two quadrates be separated from the rest by transposition, and the sides be squared, and an equation will be produced of only one universal, to be deleted by prop. 9: thus, let the equation /Q.3R+ 2+ /Q.2B—1— /Q.4R—2-—0, he separated in this manner, /Q.3R—24 /Q.2RB+4+1=,//Q.4K4 2; let the sides be squared, and they become 5h —1 + ,/ Q.6Q—1BR—2= 45 +2; then, by abbreviation, they be- come / Q.6 Q— 1K — 2 -- 3— 1B; afterwards, by prop. 9, they beome, 6Q — 1B —2=1Q—6K+49; and finally, 5 Q + 5R—11=0, otherwise 1 Q + 1R— 2! = 0. 14. If an equation consist of three universals squared, with one uninome or simple | quantity ; let two universals be transposed from the rest, and the sides squared, and an equation is produced of two roots universal to be removed by prop. 12: thus, let the equation /Q. /C2B4+84+ /Q.3R—2—2B—/Q.2Q+41=0, be transposed in this manner, /Q.,/C2B434+/Q.3R—2=2B4 /Q.2Q+1; let the sides be quadratically multiplied together, and they become ,/ Q.,/ C 3456 QQ — vy C 1024 B + 86 RB — 244 yC2B4+3B41=6Q41+7Q.32 QQ + 8B, consist- ing of two universals squared, to be deleted by prop. 12. 15. If an equation consist of four universals squared, without other terms, let two from two be separated by transposition, and the sides squared, which will produce an equation of only two universals to be deleted by prop. 12: thus, let the equation be transposed in this manner, / Q.5Q—2KR—V/Q.10—1IB—~/Q.2BR+6+4+ /Q.1Q+ 4; the sides being squared, give 5Q— 3% + 10— vy Q.208Q— 20C— 80B—1Q+2B +104 /Q8C + 24 Q + 32 B 4+ 96; which consist only of two universals, to be deleted by prop. 12. 16. Ifasingle universallissima on one side be equalled to a universallissima alone, whether 520 APPENDIX. on the other side there be a universal alone, or a universal and uninome together, or uninomes or simple quantities only, multiply the sides together to the qualities of the universal signs, and the wniversallissima sign will be removed, the other universals being removed by the preceding rules: thus, in this equation /Q.10+ /Q.5R—2=y¥ Q.34+ /Q.8B +41, universallissima is equalled to universallissima ; let the sides be squared, and they become 10 + ./Q.5B—2=8+ /Q.3B4]or7+ /Q.5BR— 2— /Q.3R +41; of which you may delete the universals by prop. 12. Another ex- ample is as follows: Of the equation ,/Q Ss.3+ /Q.2B—1=,/CSs.5+/Q.33—4 let the sides be multiplied together quadrati-cubice-supersolide, and they become 18 8 + 18+ /Q.8C—12Q46BR—1+, Q. 1458 B — 729 = 214.38 + ¥ Q. 300 BR — 400, or 15B —34+ /Q.8C—12Q+6BR—1+4/Q. 1458 B — 729 = / Q. 300 R — 400, of which the universals cannot be deleted. A third example is as follows. Of the equation / C.84 /Q.2BR—1=, C.20—4B multiply the sides together cubically, and they become 3 + / Q.2B— 1=—20—4B, or /Q.2R—1= 17 — 4B, of which you will delete the universal by prop. 9. 17. By the same propositions which have been laid down for deleting universals, so may simple irrationals, betwixt rationals, be transposed, multiplied, and then deleted ; thus, let the equation 12 —,/Q 1B = 18 be separated in this manner 12—1 R= ,/Q18; then the sides quadratically multiplied together become 1Q— 24B + 144= 18, or 1Q — 25 BR + 144 — 0, which are entirely rational. ‘Therefore, what has been said of uni- versals in propositions 9, 10, 11, 12, 13, 14, and 15, must be understood to apply to simple radical quantities. 18. If not prepared as above, there is another mode of preparing these equations; for the multiplication of simple irrationals for the most part exhibits more roots than requir- ed; thus, to take the foregoing example, 12 — ,/ Q 1 BR — 1 B, multiplied as above, re- turns the equation 1 Q — 25 B + 144 = 0, which has two valid [positive] roots, namely, 16 and 9, when truly the principal equation itself 12 — yQ1B = 15 has only one root, namely, 9, as afterwards will appear ; therefore, that principal equation, unless pre- pared according to prop. 17, may be better and more simply prepared by prop. 20 here- after, as will there be shown. 19. If, from an equation to 0 there be extracted any true root, (that is, leaving no re- mainder,) that root will be a more succinct equation to 0; thus, from the equation 1 C — 6Q+ 12 BR — 8= 0 extract the true cube root, namely, 1 R — 2 — 0, which will be an abbreviated and succinct equation; so from the equation 1 Rh — / Q36B + 9=0 ex- tract the square root, which will be true (dy Cap. 8,) namely, / Q1 BR — 3 = 0, being a more succinct equation. ‘«¢ Ther is no more of his algebra orderlie sett doun.”—(Note by Robert Napier to Henry Briggs.)

THE most remarkable fact in the history of our Philosopher’s lineage is one little known, but possessing no slight degree of historical interest. He was, through a female, de jure, an Ear] of that ancient race of Levenax, from which his family, as stated in the Memoirs, claimed a lineal male cadency. By a royal deed, dated at Edinburgh 26th March 1455, and still preserved among the Merchiston papers, James II of Scotland bestowed upon John, the son and heir of his master of household, Sir Alexander Napier, the maritagium of Elizabeth Menteith. That is to say, the King gifted him with the casualty of her marriage, due, by the feudal customs, to the sovereign su- perior in consequence of the succession of the daughters of Sir Murdoch Menteith to the family estates. The gift was, in fact, part of the settlements of a marriage which took place not long afterwards. ‘The young lady was one of two very interesting and high-born wards whose persons and estates had come, by feudal incident at that time in full force, under the guardianship of King James, about the middle of the fifteenth cen- tury. Elizabeth and Agnes were the sole surviving children, and consequently co-heir- esses, of Sir Murdoch Menteith of Rusky, son of Sir Robert Menteith, and Lady Mar- garet, second daughter of Duncan eighth Earl of Levenax. Sir Murdoch was heir-male of those Earls of Menteith whose honours, which flowed in a female line of succession, set so deeply in blood upon the same scaffold where the venerable Earl Duncan died. Thus these young ladies came to inherit between them one-half of the whole comitatus of Levenax, besides goodly baronies in “ the varied realms of fair Menteith.” Our best historians have sadly confused the history of the Levenax. Not to mention others of less note, Dr Robertson tells us that Earl Duncan beheaded by James I. was forfeited, and his possessions added to the crown. Mr Tytler, whose excellent history is still in the course of publication, has adopted the error of Dr Robertson. ‘ These execu- tions,” says he, “ were followed by the forfeiture to the crown, of the immense estates belonging to the family of Albany and to the Karl of Lennox ; a seasonable supply of re- venue,” &c. (iii, 227.) No authority is quoted by these historians in support of their assertion, and it is curious to observe the careless manner in which both of them again introduce an Earl of Lennox upon the restless stage of Scotland’s miserable commotions, without any explanation of the revival of the honours, and at periods too, when, in point of fact, no one had resumed them. But how came the Levenax to pass by inheritance, and be taken by services and retours to this very Earl Duncan, if his estates were for- feited to the crown? This important question our historians have never considered. ‘The truth is, Earl Duncan suffered no attainder in title or estates. There is no proof that he did,—there is unquestionable proof that he did not. Of this our limits only admit of a summary notice. 1. Earl Duncan’s eldest daughter and heiress, Isabella, was married to Murdoch, eldest APPENDIX. 525 son of Robert Duke of Albany, Regent of Scotland. * By the marriage settlements the comitatus of the Levenax was vested in this lady, in the event of her father leaving no legitimate son, and failing her it vested in her two sisters, as heirs-general of Earl Duncan. Isabella, now Duchess of Albany, was bereft of her father, her husband, and her family, by the executions above-mentioned. In virtue, however, of the family settlements, that lady kept possession of the whole estates of the Levenax,—exercised without challenge the rights of feudal chief,—resided on the Island of Inchmurrin in Lochlomond, being the prin- cipal messuage,—granted many charters of lands belonging to the comitatus,—and in those charters used the style “ Isabel Duchess of Albany and Countess of the Levenax,” and all this for about thirty years, the period she survived her father. 2. This state of possession was not only not disturbed by the sovereign but expressly acknowledged by him. In the great chamberlain rolls preserved in the Register-House, and bearing date from 16th July 1455, to 7th October 1456,—being the royal accounts in which the King’s interests are particularly attended to,—there is an entry which unequivo- cally declares the King’s interest in the lands of the Levenax to be simply that of Over- lord,—which expressly recognizes the countess under that title, calling her antiquacomitissa de Lenax ; acknowledges the casualty of relief to have been paid, and the issuing of a pre- cept of seisin to the heir ; and complains of continued non-entry at the same time that she is enjoying the fruits. 3. This was not a mere personal indulgence to the Duchess. Her liferent rights hav- ing fallen by her death, the comitatus came, not to the crown, but to the representatives of her two sisters; which representatives made up their titles, and took as hetrs-general of Earl Duncan, who, as those titles expressly bear, died at the faith and peace of the King ; an expression which, under the circumstances, can only mean that that nobleman did not pe- rish for treason, and was not forfeited. The original titles of these representatives are still extant, and were confirmed by successive sovereigns from generation to generation. In virtue of these titles it was that the romantic country, with which our historians have en- riched the crowns of the early Jameses, continued to descend through the heirs-general of Earl Duncan. These were the representatives of his remaining daughters, Margaret and Elizabeth, co-heiresses after the failure of the rights of Duchess Isabella. Margaret, the elder, was represented by the family of Rusky; Elizabeth, the youngest, by the family of Dernely. Elizabeth Menteith, the eldest co-heiress of Rusky, transmitted her lands in the * Every historian, from Fordun to Mr Tytler, without any exception that I am aware of, has record- ed that the Regent, Robert Duke of Albany, died 3d September 1419, I find, however, in the Regis- ter of the Great Seal in the Register-House, a charter of confirmation by James I. dated at Edinburgh, August 29, 1430, of a charter “ avunculi sut Roberti Ducis Albania,” which charter of Duke Robert is dated “ apud Falkland, August 4, 1420, an. gub, 15.” This clears up a difficulty started by Pinker- ton, that in the records the year 1423 is called an. gub. 3. of Duke Murdoch. Pinkerton explains this by the inference that, although Duke Robert died in 1419, his son Murdoch was not recognized as Re- gent until 1420. 526 APPENDIX. Levyenax, and her right to the earldom, to the Inventor of Logarithms, her lineal male representative. Agnes, her younger sister, transmitted her share to Haldane of Glen- eagles; and the lands came to the Earl of Camperdown as heir of entail of Gleneagles. Dernely, who eventually usurped the Earldom of Levenax from the elder branch, Rusky, but still through the semblance of a service to Earl Duncan, transmitted that usurped title to James VI. These proofs rest upon original records extant; and more could be added, But in one word, we put it to historians, how came the Inventor of Logarithms to speak of “‘ my landis in the Lennos,” if, as they have recorded, those very lands were added to the crown when Earl Duncan died ? Another error has found its way into history in reference to this Earldom, and that is, that Earl Duncan left a legitimate son, his heir, who is now represented ! This is record- ed by Mr Chalmers in that excellent work the Caledonia, but most incautiously from an ex parte compilation, of a modern date, by an antiquarian lawyer who wrote on behalf of Miss Lennox of Woodhead. The family of Woodhead (now represented by Mr Kincaid of Kincaid) unquestionably descends from Donald of Ballcorrach, ason of Earl Duncan. But it is just as unquestionable that he was an dllegitimate son. 1. According to the proofs already alluded to, Earl Duncan’s honours and estates pas- sed to his daughter, and in virtue of an investiture wherein she was expressly postponed to any legitimate son of her father. Yet the Donald in question was then alive, and held lands in the Earldom as the vassal of his sister, whom he acknowledges for his superior. 2. The comitatus was afterwards divided between the other daughters of Earl Duncan, as his co-heiresses, without challenge from Donald, or his lineal male representative, who continued to hold subordinate rights in the Levenax. 3. There is an original charter under the great seal, dated 25th August 1423, and preserved in the Register-House, where Duchess Isabella is styled “ Harepem Comitatus de Lenax.” Of this date the Donald in question was holding lands in the Levenax from his father Earl Duncan. 4, There is an original charter (preserved in the Brisbane charter chest) by Earl Duncan, dated 12th August 1423, and relating to lands adjoining Donald’s estate, which is witnessed by “ Malcolmo Thoma, et Donaldo filius nostris naturalibus.” * 5. There is extant an ancient charter seal of this Donald’s, which carries the arms of Levenax. But not the pure arms, nor yet with the label of an heir, but with a star on the centre of the cross. Enough has been said to meet the ridiculous pretension of Woodhead. More might be said; but, in one word, how came the Inventor of Lo- garithms to possess so much of the Levenax, if Earl Duncan left a son and heir, who is still represented ? The claim of Lord Napier to the honours of Levenax has been presented to his Ma- jesty. A case for his Lordship will be published, containing a complete history of the * Discovered by Mr Riddell.

APPENDIX. 527 partition of the comitatus, with the proofs of Dernely’s usurpation, and of the seniority of Elizabeth Menteith of Rusky, (through whom Napier claims the Earldom,) to her sis- ter Agnes, the ancestress of Gleneagles. * Next to his rights m “ the Levenax,” our philosopher’s patrimonial connection with “the Menteith” possesses historical interest. The name of Napier-Rusky is still fa- miliar to those who inhabit the beautiful vale of the Teith. The family of Rusky, the honours of whose eldest co-heiress descended to Napier, flowed from “* Sir John de Me- neteth,” second son of Walter Earl of Menteith, who was third son of Walter, High Steward of Scotland. This lineal ancestor of our philosopher has been most ground- lessly maligned; and to remove an idle calumny from the honourable house of Menteith, is to clear history of a blot anda fable. Who, in his reminiscences of nursery lore, is un- mindful of the Wallace wight, and his false friend the traitor Menteith ? 'To the nursery should that fable be confined. Some vague and scanty expressions of certain old chronicles, furnishing no details, and beyond the reach of cross-examination, had, in the progress of centuries and through the mists of the cloister, become magnified into popular obloquy against Sir John Men- teith. The tragic fate of Wallace, moreover, created a predisposition to sacrifice great names to the manes of the patriot; and at length our philosopher’s ancestor, (called for the occasion the bosom friend of Wallace,) obtained infamous celebrity. Lorp Hares, to whom the annals of his country are so deeply indebted,—who may be said to have destroyed a school of chroniclers with us, who, affecting an air of re- search, were apt to put forth the most unwarrantable assumptions,—Lord Hailes, whose fastidious accuracy, and philosophical impartiality, created a new era in the his- torical department of Scottish letters, —paused at this popular condemnation of a baron, who ranked so high among the noble and virtuous of his country, and, struck with the illustration afforded of the peculiar vice he laboured to eradicate, recorded his doubts and his dissent. None could more critically appreciate those meagre remnants of an- cient chronicles, which have been said to couple the name of Menteith with the most dishonourable odium of the fate of Wallace; but he tested their truth, or their mean- ing, by the authentic facts of the distinguished career of Menteith, and satisfied him- self that the slight expressions of chroniclers on the subject must be more rationally explained, than by making that individual baron the scape-goat for the nearly universal inconstancy, and disaffection, by which the nobles of Scotland sacrificed her single patriot. Above all, Lord Hailes scorned the fables of a mendicant minstrel of the fifteenth cen- tury, yclept Blind Harry, who took the ill-fated Wallace for the hero of his muse. Our great annalist, whose acumen was unrivalled in that walk of letters, at once perceived that to the inventive genius of that rude poet might be traced all the faitour colouring * For the most accurate antiquities of the Levenax, see Cartularium de Levenaz, edited, with a historical preface, for the Maitland Club, by Mr Dennistoun of Dennistoun, 1833. 528 APPENDIX. cast upon Menteith, which time has served to deepen ; and the few remarks he could afford, upon so minute a point in his Annals, are chiefly confined to an exposé of the fact that no contemporary authority exists for the prevalent allegation, so essential to the ca- lumny, that Menteith was the personal friend of Wallace, and then basely betrayed him. ‘«‘ Sir John Menteith,” says Lord Hailes, “ was of high birth, a son of Walter Stewart Earl of Menteith. At this time the important fortress of Dumbarton was committed to his charge by Edward. That he had ever any intercourse of friendship or familiarity with Wallace, Iam yet to learn. So, indeed, is said by Blind Harry, whom every his- torian copies, yet whom no historian but Sir Robert Sibbald will venture to quote. It is most improbable that Wallace should have put himself in the power of a man whom he knew to be in an office of distinguished trust under Edward ; but it is probable that Wallace may have been committed to the castle of Dumbarton, where Menteith com- manded. The rest of the story may have arisen from common fame, credulity, the spirit of obloquy, and the love of the marvellous.”—Annals, Vol. i. p. 281. Blind Harry, whose surname has escaped all human record, found an able and enthu- siastic editor in Dr Jamieson; no match, however, for Lord Hailes, in the walk of an- tiquities, to which both were attached. With the natural leaning of an editor, Dr Ja- mieson, though he candidly admits the fabulous tendency of the minstrel in general, is anxious to redeem the main incident of the poem, and to place it among the stores of authentic history. This he attempts, not by fortifying the fact with proofs, but by chal- lenging the critique of Lord Hailes, in a vein of flimsy and fallacious controversy that is not difficult to answer.—(See Notes to Dr Jamieson’s Wallace and Bruce.) Mr Tytler, in his History of Scotland, instead of expanding Lord Hailes’s remarks, has treated his readers with an elaborate rifaciménto of Dr Jamieson’s controversial note, to which he has added nothing of any consequence, except a most unmeasured increase of the disrespectful tone assumed towards Lord Hailes by the editor of Blind Harry.* Our limits are too confined for long quotations and a minute critical exposition. At present no more can be done than to offer what may suffice to justify our remarks. The case against Menteith is, that he was the especial friend of Wallace, and then basely and meanly betrayed him,—or there is no case at all. Every reader of Scotch history knows this. Nearly all the nobles of Scotland (including Bruce and Randolph, who were among the noblest,) were, during the feverish state of subjugation under which Scotland suffered, alternately false to their country, and faithless to their conqueror. If * Mr Tytler’s note is prefixed to Volume Ist of his History of Scotland, and commences, “ I have else- where observed that Lord Hailesis fond of displaying his ingenuity in whitewashing“dubious characters ; and that, with an appearance of hypercritical accuracy in his remarks upon other historians, he is often glaringly inaccurate himself.” The charge of whitewashing is bold froma Tytler. Our historian really adds nothing to the critique of Dr Jamieson. He only quotes in addition two old English chronicles, the Scala Chronicle, which actually says nothing to the point at all; and Langtoft, which, so far as it is intelligible, refers the friendship and treachery, not to Menteith, but to one Jack Short, a retainer of Wallace’s. APPENDIX. 529 Sir John Menteith had acted the same part, (which he did not,) still there would be no ground for making him the political traitor par excellence. Accordingly, that is not the charge against him. He is charged with peculiar perfidy towards Wallace. He is made the Judas of profane history. This is the charge upon which alone Mr Tytler can say, that “ it was natural that the voice of popular tradition should continue from century to century to execrate the memory of such a man.” ‘This is the charge which Lord Hailes said was not proved, and without proof of which the calumny is baseless. True, certain old chroni- cles couple, in a few words, the name of Sir John Menteith with the capture of the patriot. But Scotland was then completely under the yoke of Edward, and Men- teith was at the head of the executive in the district where Wallace was captured ; and held, for England, the castle of Dumbarton, to which Wallace was at first con- veyed. This fact is sufficient to account for the names of Menteith and Wallace being so coupled, and for the poetical fiction of Blind Harry. Dr Jamieson admits it to be so, when he says, “ But at this time, we are told, (by Lord Hailes,) the important fortress of Dum- barton was committed to his (Menteith’s) charge by Edward; here it would seem the learned writer fights the poor minstrel with his own weapons; for I find no evidence of this fact in the Foedera, Hemingford, or the decem Scriptores ; and Lord Hailes refers to no authority, so that there is reason to suspect, to use his own language, that he here ‘ copies’ what is said by Blind Harry, whom no historian but Sir Robert Sibbald will venture to quote ; if Harry’s narrative be received as authority, it is but justice to receive his testimony as he gave it.” ‘The affectation of considering Lord Hailes as having bor- rowed this important fact from Blind Harry, the very authority he was crushing, can never rank higher than a sneer. We are content to select this passage as the test of the critique of Harry’s editor. Had the Doctor read the Annals he must have found that Lord Hailes relies upon official records for the fact. He quotes Ryley, Placita Parlamentaria, repeatedly, both in reference to the circumstances attending the capture of the patriot, and also the settlement of Scotland at that period. He gives, in his notes, extracts from that record, and shows not only that King Edward then appointed Menteith sheriff of that county, but that he had continued him in the command of Dumbarton Castle, which Menteith had previously held for England! Which, then, is right? Dr Jamie- son with his sneer, or Lord Hailes with Ryley? Let us attend for a moment to facts and dates. In the year 1303, Comyn and others assembled a large force before Stirling for the purpose of protecting that fortress from reduction by Edward I. The aged but invincible monarch, who was there in person, dispersed them without difficulty, and Comyn and his followers formally submitted to the conqueror, 9th February 1303-4. At this time, Menteith was still an adherent of Edward’s, and not with Comyn. After this victory, Edward assembled a parliament at St Andrews, from whence he issued a sum- mons to the garrison of Stirling, which refused to surrender, and that memorable siege commenced on the 23d April 1804. The castle surrendered on the 20th of July follow- ing. It was in 1805 that Wallace was captured, and he was executed in London upon the 23d August of that year. Now I find among the transcripts of ancient deeds in the 3x 530 APPENDIX. Advocates’ Library, the grant from Edward I. to Sir John Menteith of the sheriffdom and castle of Dumbarton ; and it calls upon all the subjects of the conqueror to be vigilant in aiding, and faithful in obedience to, Menteith in his important jurisdiction. It is dated 20th March at St Andrews. No year is mentioned, but unquestionably it is March 1303-4, when Edward was at St Andrews before the siege of Stirling, which occurred in the following month.* This deed appears to have escaped Lord Hailes, but it proves that he was not deceived in his reliance upon Ryley. There, in the meantime, we leave Blind Harry’s editor. Now we venture to say that Mr Tytler would have been better and more safely occu- pied in redeeming Lord Hailes from such an attack, than in repeating Dr Jamieson. Has our excellent historian himself always carefully read the annals he impugns ? We fear he has not, if we may judge from the fact that he has quoted them hastily and inaccurately. There is a spurious chronicle, of which no one can give a distinct account, called Rela- tiones Arnaldi Blair, in which it is said that, upon a certain occasion in the year 1298, Menteith, Wallace, and some others, went together in arms upon a warlike expedition. The passage asserts nothing about friendship between Menteith and Wallace, beyond the bare allegation that they were in arms together. Lord Hailes, in his Annals, takes this authority and destroys it. He convicts it of anachronism, inconsistency, and im- probability ; and very properly rejects it as worthless. Now, both Dr Jamieson and Mr Tytler quote this passage against Lord Hailes, meagre and inconsequential though it be, as if it had entirely escaped the observation of the annalist; while the fact is, that he examined the authority critically, and his antagonists have not. Again, the object in quoting this authority against Lord Hailes is to establish the fact of friendship at one time existing between Menteith and Wallace. ‘This it by no means does, even could it be relied upon. If any thing, it proves a solitary instance of military intercourse or co- operation, but nothing more ; and the whole ‘calumny against Menteith depends upon the allegation of a base breach of private friendship. Here, again, we are constrained to say, that Mr Tytler has not read the Annals. He exclaims, “ Hailes has also remarked, that he has yet to learn that Menteith had ever any intercourse on friendship and familiarity with Wallace; yet that Menteith acted in concert with Wallace is proved by the fol- lowing passage from Bower, preserved in Relationes Arnaldi Blair.” Now what Lord Hailes says is something quite different, though a very little word makes that difference. He says, that he has “yet to learn that Menteith had ever any intercourse oF friendship or familiarity,” &c. A proof of their having upon one occasion acted in concert would not prove the friendship alleged, but would certainly contradict an assertion of “ no inter- course or friendship and familiarity ;” such proof, however, manifestly would not meet the allegation of “ no intercourse of friendship or familiarity.” Now, friendly and familiar * Wodrow’s MSS.

This he elsewhere shows pointedly by putting the word friend in Italics,—an ocular emphasis which I do not find preserved in Mr Tyt- ler’s quotation of that passage. But our historian, with regret we say it, has, in respect of Sir John Menteith, forsaken his true mistress, the Genius of History, to follow that false Duessa, partial controversy. He has omitted to record the historical facts of Menteith’s career. He has recorded that “« Sir John de Menteith, a Scottish baron who had served along with and under Wallace against the English, deserted his country, swore homage to Edward; and employed a servant of Wallace to betray his master into his hands; that he seized him in bed,” &c. and from these violent assumptions our historian deduces his moral remark, that “ it was na- tural that the voice of popular tradition should continue from century to century to eze- erate the memory of such a man.” But to no redeeming point in the long career of Men- teith,—to no circumstance, however authentic and within the pale of legitimate history, which might contradict this mixture of fable and calumny, does he even slightly allude. Let us turn again to facts and dates. Mr Tytler, in his own history, particularly records the battle of Dunbar gained by the Earl of Surrey in the year 1296; and also the fact that the principal Scottish no- bility, there taken prisoners, ‘‘ were immediately sent in chains to England, where they were for the present confined to close confinement in different Welsh and English castles; after some time the king compelled them to attend him in his wars in France, but even this partial liberty was not allowed them till their sons were delivered into his hands as hostages.” But our historian, while he particularizes other nobles, does not record that Sir John Menteith was one of these prisoners ; and that, so far from there being the slightest evidence that he was among the first to bend to the conqueror, his name does not occur in that degrading document the Ragman Roll. ‘There can be no question that this is the true history of Menteith’s involuntary allegiance to Edward I. In the Rotuli Scotie will be found, under date 30th July 1297, the mandate of the English monarch, that the “© magnates” of Scotland, taken at Dunbar, should be liberated, and have their lands again, as they were about to perform military service in France and elsewhere. It will be remembered that this was the expedition in reference to which Edward said to Hum- phrey Bohun, the haughtiest earl in England, “ Sir Karl, by God, you shall either go or hang.” Sir John Menteith is one of the Scotch nobles particularly mentioned as being released upon the condition of foreign service. Nor is this all. The Fa- dera afford the very terms of the oath which Menteith was compelled to take. Up- on the 9th day of August 1297, Comyn was, by the king’s command, released from prison, and made to swear with his hand on the holy Scripture, that he would ac- company Edward to France against his enemies, and serve him faithfully according to the terms of a formal written obligation containing the highest penalties; and, moreover, that before the expedition set sail, he, Comyn, should find sufficient se- curity. Immediately follows, in this public record, that an oath to the same effect, and precisely in the same terms, was extorted from Sir John Menteith,—‘* Eodem 532 | APPENDIX. modo, juravit et literam dedit, et manucaptionem dare promistt, Johannen de Meneteth, frater comitis de Meneteth.” Not one word of this is recorded in Mr Tytler’s history, although among his charges against Menteith is, that ‘‘ he deserted his country, swore homage to Edward,” &c. That monarch returned from the foreign campaign, in which Menteith accompanied him, upon the 14th March 1297-8. During his short absence, Wallace had reached, through a brilliant career of arms, the governorship of Scotland. Edward, upon the 22d July 1298, a few months after his return, met the patriot at Falkirk, where the humbler star of Wallace paled before that of Plantagenet. While most of the Scottish nobles were continually changing sides, I have not been able to discover a vestige of evidence or probability that the services of Menteith were for a moment re- stored to Scotland, until after the death of Edward I. His oath,—his bond,—his hos.- tages,—the heavy penalties stipulated, are his excuse. Had Bruce so good a one for his fickle conduct ? Menteith may even have conceived an affection for his conqueror while serving with him abroad; and, foreseeing no brighter prospect for his unhappy country, have hailed Edward, with abated reluctance, as her king. When and where was his private friendship with Wallace contracted? ‘The patriot only emerged from comparative obscurity after Menteith was a prisoner of war in England! When and where did he serve “ with and under Wallace against the English?” The time and occasion alleged by Mr Tytler, following the spurious Relationes, is a miserable expedition of fire-raising, a case of creeping arson, said to have occurred in the neigh- bourhood of Ayr, upon the 28th August 1298. Now it is incredible that Menteith could have been engaged in any such expedition a few months after his return from abroad with the king of England, if, indeed, he did immediately return with the con- queror. ‘There is no authority for the fact, except the Relationes ; and Lord Hailes (though his adversary does not notice it) destroyed that authority, and showed that ano- ther is also named by that unknown writer, as a companion of Wallace upon this occasion, who was killed at the previous battle of Falkirk. Aware of this difficulty, and anxious to prove one instance of companionship betwixt Wallace and Menteith, Dr Jamieson endeavours to make out the date in the Relationes an error, and to transfer the incident to the time of the treaty of Irvine in 1297. Be it so. Had Blind Harry’s editor taken the Rotuli Scotie along with him, he would have found that of that other date Menteith was a prisoner of war in England! ‘Thus the assertion, that Menteith deserted his country, and served under Wallace, is absolutely inconsistent with the public records, which our historians overlook, while clinging to a legendary fable in the vain hope of discomfiting the father of accurate Scottish history. But, says Mr Tytler, the memory of Menteith has been naturally execrated from gene- ration to generation !_ And why does our historian not record the facts (worth a million of his legends) that prove how trusted, honoured, and beloved Menteith was in his own generation after the death of Wallace ? Again let us turn to facts and dates. By the deed already quoted, of date 20th March 1803-4, it is proved that Sir John Menteith was in the highest favour with Edward I. and was ae with the most important jurisdiction in APPENDIX. 533 Scotland. This destroys all probability that Menteith, between this period and his return from the foreign campaign, had any dealings with Wallace, far less served with him against the English. The patriot was captured within Menteith’s jurisdiction, or placed under his charge before being sent to England, where he was executed 1305. Edward I. died 7th July 1307. Edward II. went to the continent about the close of that year, and toa state paper, by which he provides for the quiet of Scotland during his absence, appears the name of Menteith. This indicates that he had not swerved from his oath to Edward I. before that monarch’s death. But it is proved by the Feedera, that, in August 1309, Men- teith was the leading commissioner for Scotland to conclude a truce with England. He was joined with Sir Nigel Campbell. Mr Tytler does not record this negotia- tion.* But it is most material. It proves that Menteith had taken the earliest opportunity to return to his country after the death of Edward I. released him from his bond; and that he stood in the highest esteem with both countries. Had his con- duct towards his country, or towards Wallace, deserved execration, Menteith would not have been associated with the King’s brother-in-law upon this most important mission. In 1615 Menteith was the companion in arms of Randolph, the King’s nephew, in the expedition to Ireland. In 1616, Menteith accompanied the same nobleman on a mission to England. Menteith and Randolph were bosom friends, companions in arms, and in diplomacy ; and here is Mr Tytler’s own translation of Barbour’s character of Randolph ; “loving honour and loyalty, and hating falsehood above all things, ever fond of having the bravest knights about him whom he dearly loved.” ‘This companionship of Menteith and Randolph is not to be found in Mr Tytler’s history, but is proved by the public re- cords. Menteith is one of the barons who, in the year 1320, signed the memorable ma- nifesto of Scottish independence. Our historian records this spirited appeal with the highest commendation, but does not record that one of the names attached to it is “ Johan- nis de Menteth custos comitatus de Menteth.” Menteith was one of the commissioners and conservators of the truce with England at the famous treaty of Berwick in the year 1323. Mr Tytler has not recorded this fact, or indeed any fact in favour of Menteith, who died not long after the above date, without a stain upon his shield. Under the circumstances, his allegiance to Edward I. was no stain at all. Ancient chronicles, meagre and equivocal in their expressions, some of them English, some of them anonymous, or of doubtful authorship, some of them unintelligible, none * This was the negotiation with Richard de Burgo Earl of Ulster, 2d and 21st August 1309.—Fe- dera. It was before this, (but after Des Roches’s treaty,) namely, 30th July 1309, that Edward, alleg- ing the truce to be broken by the Scots, declared war. It was after the negotiation of Menteith and Campbell with De Burgo, that the king of France sent Count de Evreux to Edward, namely, 29th November 1309. Now Mr Tytler omits entirely De Burgo’s negotiation—speaks of Count De Evreux’s mission as that which immediately followed Des Roches’s, and then refers to Edward’s declaration of 30th July 1309 as subsequent to Evreux’s mission which occurred in November following. Lord Hailes, on the other hand, is minutely accurate with regard to all these transactions. Correct Tytler, Vol. i. pp. 277, 278, by Hailes, second Vol. pp. 28, 29; and by the Federa. 534 APPENDIX. of them susceptible of being thoroughly sifted upon the point, and the most explicit of them written long after the event, are referred to triumphantly by Dr Jamieson and Mr Tytler, to the exclusion of legitimate history. I must here content myself with a single instance of Mr Tytler’s aptitude to grasp too hastily at these shreds and patches of dim and legendary records. Wyntoun, one of the best of the old chroniclers, but not born.for more than half a century after Wallace’s death, simply records that Menteith “tuk in Glasgow Willame Walays.” ‘This proves nothing. But our historian, in quoting it, also quotes the rubric of the chapter which says that Menteith “ dissavit gud Willame Walays.” Now Wyntoun’s enthusiastic editor, Mr James M‘ Pherson, who brought that chronicle into repute, scouts the fable of Menteith’s treachery, and adds, ** Wyntoun only says that he ‘ tuk Walays:” the word “ dissavit” being the addition of the rubricator, and probably from the report then circulating.” Mr Tytler does not meet this. As for the evidence said to be afforded by the Scotichronicon, 1. It is not contemporary. 2. The scanty expressions attributed to Fordun on the subject cannot with certainty be separated from his continuators and interpolators. 3. If used by For- dun, they show that that prolix chronicler was acquainted with xo details of Menteith’s perfidy, or he would have noted them. 3. Bower, Fordun’s alleged continuator and in- terpolator, is still farther removed from the event. He, too, has given no details of the perfidy, and obviously had none to give. 4. The violent tirade against Menteith, con- tained in the Relationes, and by some attributed to Bower, destroys itself; and Mr Tytler has wisely excluded from the pages of his history all the monkish trash, attributed to Bower on the subject of Menteith, to which in his controversial note he makes a vague and general reference. But we take fearlessly, what the antagonists of Lord Hailes have rejected, the Federa and the Rotuli Scotie, against the whole field of subsequent chroniclers and popular calumny. The moral principles which influenced one individual towards another, five hundred years ago, the degree of private personal friendship — existing between them, and the minute circumstances of action composing the merits of such a case, are just those questions of all others in which even a contemporary chro- nicler, expressing popular, perhaps his own individual opinion, cannot be relied upon. It is a fatal mistake in a historian to suppose that because an authority is old it must be trust-worthy. Mr Tytler parades his legendary lore as if he had found charter and seisin against the Menteith. He arranges his authorities with the air of marshalling veteran, irresistible troops. But, at the best, they are like Falstaffe’s tattered recruits,— “ ragged old-faced ancients,—nay, and the villains march wide betwixt the legs as if they had gyves on,—there’s but a shirt and a half in all their company.” THE END. * EDINBURGH : PRINTED BY JOHN STARK, OLD ASSEMBLY CLOSE. i @ at vv —_ a _ 4 pi an ' a 4 aoe ae, &: sa) a; APA ss i Aa me PPB Fat ayers Praeon CS eae ae Se aie Sosies er aed een ee a ae aie LS a ae Se eh ae Re Hin = Po Sis ge hes Sir oye Gia Bp ea is ome ee as ie ae ae Stel ioe as ed ti arin Pera Ap eS fit nyse aw peo Or eae 2 iene Ri er a aaa 3S Pic ee ee aoe oe eth Sogn i mug ts a oe pola Te ie mereanants cee ye Geos meyer ey PEE (Ne SS ode eons BP ae Dhak ars eee a a a ec eit A yaw ee mir ecmies Sap Pie ite je aie Bae . ce : $ i > portent ary ; \ sey : Se 7 tire - ue Se eee A Fe ee eee ee ipso = fr ogponirt ie preys im Si SOILS I ee etl dei er a eat Sie ee TI ite oe ee . : ya eeereee ne Sg ae eae ae / SP LS ee a a ’ i = neem . eS a a Te ae te ge geatiy we ee eee ENS “ - or SEPP TRE ALTA 2 Cr 4. a fi PO OIE ne add De OFF ee ‘ a yeaa PPC EL TT Lr r Satara ag eh ee mad os oe ee
