PREFACE A 批 ​PREFACE. I T may juftly be remarked, that many of the moft effential Difco- veries, made by the earlier Ages; and which we at this Day reap the benefit of, are enjoyed by Millions, who never confider the Inconvenience and difficulties, they would be expofed to without them. Men write to their ab- fent Friends from their Chimney Corner, receive their Anfwers in the fame Place, hear Men fpeak who have been dead a thousand Years, and leave their own Sen- timents recorded, for thofe who are to live a thousand Years hence, as if it were nothing to be wondered at! The Frequency, and the eafy Attainment of Reading A 2 iv PRE FACE. Reading and Writing, has almoft worn out of the mind of man, how won- derful the contrivance is. THE Romans, amidst all their Arts, were deftitute of the greateft of modern Conveniences, which we enjoy almoft without perceiving it. We have Win- dows and Glafs Doors which let in the Air, and the Light, at the fame Time that they fhut out, the Injuries and In- conveniences which attend them, and exhibit to us, even in the interior Parts of our Houfe, the variegated View of Nature, which transform the Winds, the Frofts, and the Tempefts, into a mag- nificent moving Picture before our Eyes. The Peafant, in thefe our Days, is thought miferable, who wants a Luxury which a Roman Emperor was a Stranger to! The Invention of Letters, and the Art of Printing, duely confidered, feem to have had fomething more than hu- man in it. WHO the Authors of thefe rare In- ventions were is uncertain, but it is moſt likely, PREFACE. V likely, the hint was taken from the Egyptian Hieroglyphics, and yet how poor was that Method of conveying their Sentiments? for though we cannot, at this diſtance of Time, decypher thoſe Monuments of Antiquity perfectly; yet, by what we do know, it is very evident, that method was vague, confined, un- certain, and incapable of conveying hiftorical Events. Plutarch fays, there was a Temple in Egypt dedicated to Mi- nerva, on the Front of which was painted, an Infant, an old Man, a Hawk, a Fiſh, and a Sea-Horſe. The Mean- ing of which, he fays, is," YOUNG "and OLD know GOD hates Impu- "dence." But the true meaning may be this; The Infant, which is the first Fi gure, reprefents Man's firft Entrance into the World; and the old Man im- plies the going out of it: The Falcon, GOD; the Fish, Hatred, becaufe they hated Fish bred in the Sea, which fymbolized Typhon; and by the River- horfe, Murder, Impudence, Violence, sd and vi PREFACE. and Injuftice; for they fay he killeth his Sire, and ravifheth his own Dam, which may import, O you that enter the World, and go out of it, know, that GOD hateth Injustice! and yet neither may be any thing to the purpoſe, as it can- not but be very difficult for Men at this Day, to explain certainly; what many Men of their ownTime and Nation, muft have differed in the Senfe of. AFTER the Invention of Letters were thoroughly known, and ufed by the Learned of all Nations, it is natural to conclude, that particular Men, to ſerve private purpoſes, would contrive fome fecret Manner of correfponding, by which they hoped to carry on Plots un- diſcovered, or to give Intelligence either to, or from a City befieged. And it was for many Ages believed, that fuch a cor- refpondence might be carried on by Con- federates, inexplicable to any other Per- fons; but fuch is the Craft of Man! that it is fcarce poffible for a Letter in Cypher to be written, fo as not to be PREFACE. vii be decyphered, without any Clue, but a clofe application to the Letter itself; and that too, though it were writ in a Language, the Decypherer does not underſtand. A diftant Relation of mine, of the Name of Blencowe, was the firſt Man who had a fixed Salary from Government as DECYPHERER. And as the manner he got it, would do Honour to the Me- mory of the Minifter who gave it him, I am forry the Minifter's Name, as well as the Fact, is out of mine; but upon my Relation hearing that fuch an employment, with a fixed Salary annexed to it, was to be fettled; he repaired un- known, and unrecommended, to the then Secretary of State, and afked it. The Secretary feeing a Stranger, and hearing a requeſt fo contrary to the ufual Etiquette of fuch bufinefs, afked him what his pretenfions were to the employment he required? becaufe, Sir, faid he, I am qualified for that which I aſk. Are you, replied the Minifter viii PREFAC E. Minifter; then decypher thefe two letters! letters which had lain fome Time be- fore him unexplained, for want of fuch a Perfon; and which, perhaps, occa- fioned the refolution of having an efta- bliſhed Decypherer. In a few days the Letters were brought to the Minifter, properly and evidently explained, and my Relation thereupon had the Ap- pointment. And though this Matter of Decyphering, as well as writing in Cypher, is now very commonly practifed, yet, I have met with fome Men, even of Senfe and Learning, who have doubted the poffibility of decyphering a Letter fo written; and rather think the decypherers make out fomething plaufible; and not being eafily detected, pafs themſelves off as Men who poffefs an Art, not to be ac- quired. In the following fheets it fhall be my endeavour, not only to fhew the poffibility of it, but even to enable thofe very Men who doubt it, or any Man of common capacity, to read a letter, written in Cypher, in a few Shini hours: PREFACE. ix hours; nay, perhaps, in a few minutes, though the Epiftle be compofed of four- and-twenty arbitrary Characters, made by the Writer, which the Reader had never ſeen before; and though this be the eafieft Method of writing in Cypher, and confequently the readieft to be ex- plained, yet it is what a Man of good fenfe, who has never confidered the Matter attentively, will at firft think very difficult; but in a few hours confideration, be as much furpriſed as pleaſed, at the unfolding of this feeming- ly occult Art. I have not the vanity to think myfelf capable of inftructing thofe who already practife this Art, but of leading thoſe who doubt it, or who may find a rational Exerciſe for the mind (and particularly young people) into an habitude of thinking; for it cannot be doubted, but that any one Rule laid down, for a methodical Way of thinking, on any one Subject, will ena- ble the mind, to employ itſelf afterwards, much better, on all other Occafions; and therefore, x PREFACE. therefore, I would recommend this Kind of Study to very young Gentlemen, as an entertaining, edifying, and innocent Amuſement at prefent; and of more Importance to their riper Years, than they are aware of. If it be objected, that bad ufes may be made by a know- ledge of the Art of writing in Cypher, I answer, fo may writing without; a man who cannot write, cannot commit a Forgery; but if he is difpofed to be diſhoneſt, he may break open a Houſe. Storb 3001 (algeng bes bandgob mont get od va 201 A TREATISE ON THE Art of Decyphering, &c. N order to write with fecrecy and fafety in Cypher, the firſt care muft how can be to avoid fufpicion; the next, that it hat be done be difficult to decypher if fufpected; even Vain, and laftly, that it be ſo contrived, as to paperes be fit for diſpatch, and the fenfe easily be suspected made out, by thofe who are entruſted with the key. And if fuch a method 29. 36.73 can be contrived, to write fecretly with 79,88 all theſe advantages, and yet be fo cun- ningly done, as to elude the Decypherer's art, it may then be justly confidered an ingenious contrivance, whereby the moſt dangerous correfpondence may be car- ried on by wicked-difpofed people; or the [ 12 ] the moft fafe, ufeful, and neceffary in- telligence, may be fent from foreign Embaffadors and Generals to their own country; as well as the private inftruc- tions of their Princes to them, without a poffibility of being difcovered, tho' the meffenger (which is often the cafe) ſhould be murdered on the road, and his diſpatches taken, for that purpoſe. However, to avoid fufpicion, is a very effential confideration; for when an in- tercepted letter is fo writ as not to be intelligible; yet, it explains itfelf fo far, as to inform the intercepter, that it conceals fomething, which his curiofity alone urges him to difcover; and when that is fet about in good earneft, if the writer has been guilty of treafon or murder, he will be in great danger of meeting with his juft reward; for there is fcarce any thing writ in Cy- pher, however ingenioufly contrived, which in thefe days, can lie long hidden for want of a Decypherer, tho' perhaps there are too few who have made this their fludy. EVERY [ 13 ] EVERY thing which comes from a fuf- pected hand, fhould be carefully exa- mined, for a very wicked defign may be conveyed in a letter, which, at firft reading, may feem an innocent epiftle, from one friend to another; and yet, upon a clofer examination, may appear to have an hidden meaning, of the moſt evil tendency. How far it may be right or wrong to publifh a treatife on this art, I am neither able, nor in a fituation, to determine; but what has encouraged me to believe it will be of ufe, is, that the great Lord Bacon, in his ADVANCEMENT of LEARNING, complains, that the art of Decyphering is wanting; and has himſelf given one of the moft ingenious methods of writing in cypher, and the moft difficult to be decyphered, of any yet contrived. His authority, therefore, juſtifies this my feeble attempt, wherein I fhall not only mention thofe feveral methods of fecret writing practifed in former ages, as well as the latter, but alſo point out fome rules to be obferved, in order [ 14 ] order to decypher them; which, if care- fully attended to, will enable any perfon, of common capacity, to read a letter in a very ſhort time writ in common cypher. THE Abbot Trithemeus, in recommen- dation of his Polygraphy, afferts, that he who underftands his mother tongue only, may, by the knowledge of this art, come at the fenfe of an epiftle writ in Latin; and though that is not strictly true, yet it is certain, that a man who underſtands no other language than Engliſh, may be able to reduce a letter, writ in Latin Cypher, into proper order by being well acquainted with the rules of Decypher- ing; and when that is done, it will prove a very powerful excitement to the De- cypherer, to know the meaning of thofe letters and words he has been at fuch pains to dredge from their obfcurity. It may be faid, that this art fhould be known, and practifed only by Officers of State, or the Generals who command an army; but may not a private centinel fave an army, or a city, by decyphering In to all Officers, even vers, even Ensign should be Engine ears. 51 [ 15 ] ; an intercepted letter? Great under- takings require fudden action and if cypher is to be carried first to the General, and then to a Secre- tary of State, before it can be under- ftood, the defign may, and will, moft likely, difcover itself first, by an effectual, and perhaps fatal, execution. Thofe who have treated on this fubject, even fo lately as within an hundred or an hundred and thirty years, have imputed witchcraft to belong to this art! Thanks to the power and wildom of an Engliſh Parliament, who have driven all thoſe evil doers, either into the Orkneys, or confined them among the highlands in Scotland, or the mountains in Wales; for though I live among the latter, I am under no apprehenfion of being car- ried to the Trying-pool; yet I lately faw a conjuring book at Abergavenny, in the poffeffion of a bookfeller, which could not be worth one penny, but for which he aſked a guinea and a half, and declared he gave twenty-feven fhillings for it! at the [ 16 ] the requeſt of a tradefman who wanted to know who tole his working tools; and a worthy clergyman, in my neighbour- hood, was lately under ftrong apprehen- fions of being ruined, for having read the burial ſervice over a poor harmleſs, inoffenfive old woman, fome who either do, or who ought to know better (but whom he knew to be his enemies) had made many enquiries about the de- ceafed; and whether there was not, upon fome part of her body, a tet whereby fhe gave nouriſhment to her fa- miliar. That fuch abfurd notions ſhould remain amongſt the lowest dregs of the people in every country, is not to be wondered at; but that Magiftrates, and men of rank and education, fhould give ear to fuch idle tales, is a mortifying re- flection, as it may tend to many great and unforeſeen mifchiefs, if the common people's fufpicions have the leaft encou- ragement from thofe they think wifer than themſelves, and they always take riches [ 17 ] riches for wifdom. There is no faying that the firft old woman they meet, mut- tering to herfelf, which is a common and natural infirmity attending age, poverty, and living alone, may not die, the moft violent, and dreadful of all deaths! i. e. by the hands of an enraged, or fuper- ftitious rabble. THAT the art of fecret writing, or of fecret information, is of great antiquity, is very certain; of what antiquity, is not very material now to enquire: however, thoſe who have leifure, and learning fuf- ficient, may fee what Polybius has cited, from ancient authors, who quotes Æneas, Cleomenes, and Democritus: befide thefe, as Biſhop Wilkins obferves, Julius Afri- canus, and Philo-Mechanicus, two ancient Grecians, have alfo treated of this fub- ject; and the military fignifications, in ufe among the Romans, are mentioned by Vegetius and Frontinus: there is like- wife a volume writ upon the farne fubject, by Janus Gruterus, commonly thought to be the work of Cicero and Seneca. But in latter times are the Abbot Trithemius, B Bap- [ 18 ] Baptifta Porta, Ifaac Caufaban, Selenus, Voffius, and many others, in various lan- guages; and among the reft, the im- mortal Lord Bacon, in his work, fo juftly called, the Advancement of Learning, has thought it a matter wor- thy of his ferious attention. It will be quite fufficient for the purpofe, to commence this enquiry, by examining the fecret ufe made of the Lacedemonian Scytale, faid to be the invention of Ar- chimedes. For this purpoſe there were provided two round ftaves, equal in length and fize; one of which was left in the cuf- tody of the magiftrates; and the other was taken by the General, who com- manded abroad: fo when the Magif- trates had any private inftructions to fend the General, or the General any fecret information to convey to the Magiftrates, the method was, to wrap a narrow piece of parchment round the ftaff, in a fer- pentine revolution, fo that the edges might meet clofe together; and then write their letters upon both the edges, half [ 19 ] half the character on each fide; and thus, when the parchment was unrolled, there appeared nothing but imperfect pieces of letters, but which were eafily put together upon a ftaff of the fame fize, and read by the confederate party: but notwithſtanding the feeming dif- ficulty of reading a fcrole, fo writ, with- out the ftave, there are many ways by which it might be made out, as Scaliger in a few words clearly demonftrates, for fays he, only twift the paper, or parch- ment, fo that both pieces of the first divided letter may be joined, and that will give the true circumference of the feytale to frame another by; but I wonder Scaliger did not think of a much more ready method, and that is, by cutting the fcrole quite through the middle between the half letters, and then, by applying the two broken edges of the letters together, on a table, the letters will appear perfect, and confe- quently the reading be expofed. JULIUS CAESAR'S method was, to take the d for thea, and the e for b, and thus changing B 2 [ 20 ] 91 changing the order of the alphabet, rendered his epiftles, as he thought, inexplicable to all, but thofe to whom he intrufted the key. AUGUSTUS CESAR put b for a, c for b, and two xx's for a. By the firft method the words JULIUS CESAR would appear thus: myhmyw fhwdu Julius Cefar By this it appears, that the leaft alte- ration of the alphabet, will render the well known ufe of the letters, in their proper order, quite as uncouth; nay, rather perplex a young decypherer more than any new invented alphabet of ar- bitrary characters; becauſe the examiner will not readily diveft his mind of the proper power of the letters he fo well knows the ufe of. In the plate annexed I have given a fpecimen of a fentence lately fent me, compofed of arbitary characters, and which I fhould have read in lefs time than they were writ, had not the laſt letter, of the laft word but one, been wrong, which fhould be two ftrait lines [ 21 ] lines inſtead of one, as the fecond letter of the fecond word, is, AND this it was which rendered it dif- ficult to make out the fenfe, even after I had got moft of the words complete. Now whoever will fit down, and confider ſeriouſly the above characters, (I mean one who has never before made any en- quiry into this matter) will, in half an hour's time, however he may be perfuaded at first fight of the difficulty of reading it, be agreeably convinced to the contrary: obferving, that the laft letter of the laft word but one is wrong, but I chofe to give it, as I received it; not that there is any peculiar art ufed either in the fenfe or in the compofition of the characters, but as it will fhew the juftness of the following remarks :---Firft, then, ob- ferve, that the fair maker of this alpha- bet (for it was done by a lady of rank). or the maker of any other, who has not well confidered the matter, will natu- rally begin with a character to reprefent a, and fo on down to z; therefore the Decypherer muft avail himself of this advan- [ 22 ] advantage, among many others, and conclude, that thofe letters which are moft fimple, are neareſt the beginning of the alphabet; and confequently, that thofe which are made up of many ftrokes, and moſt complicated, are to- wards the latter end, becauſe as the maker proceeds, his invention must go to work, and inftead, perhaps, of one ftroke, to reprefent a letter, he muft unite two or three: this is an obferva- tion I have often made, and have fcarce ever feen a new invented alphabet that had not this weakness in its compofition; and the ſpecimen here annexed, is a ftrong confirmation of it. However, as an expert practitioner in this art, would most likely take the staff by the other end, it will be neceffary to be ap- priſed of it. The next thing to obferve is, what letters occur ofteneft, and thoſe you may conclude are vowels, and that which is moft frequent, to be an e---as e in Engliſh occurs oftener than any other letter. Where you find characters doubled in the beginning of a word, it will [ 23 ] will be neceffary to confider whether it be not fome Welch word as Lloyd, Llan- daff, or Aaron, Eel, Jilt, Vulture, &c. In a word of three letters, beginning and ending in the fame characters, fome vowel is probably between, as did, or 'e're; but e is eafily difcovered; and that one letter being obtained, is of in- finite confequence towards recovering with it the other twenty-three. IN English, the e is continually em- ployed, as in fee, be, ever, fpeed, need, deference, excel, excefs, &c. though this will not hold good in Latin, as e, and i, are equally frequent in the latter, and next to thefe, a, and u; but o, not fo frequent as any of them. When you meet with a character doubled, in the middle of a word of four letters, as you will perceive it to be in the above cy- pher, it will be neceffary to confider what words of four letters are fo fpelt. It is probable the vowels e or o, are thefe; as meet, feel, good, book, look, &c. In polyfyllables, where a double character ap- [ 24 ] appears in the middle of a word, it is for the moſt part a confonant; and if fo, the preceding letter is always a vowel. In confidence, therefore, that the eaſy cypher here given, will be foon difclofed, by any perſon who will beftow half an hour's confideration upon it, I fhall leave it to speak for itfelf, and not tempt an impatient fcholar to turn to the fo- lution, or to apply to the Lord Mayor of London, for the fenfe of it. OBSERVE alfo, that i, in Engliſh, never terminates a word, nor a or u except in fea, you, or thofe, and thus by comparing the frequency of the letters, you will ge- nerally find e occur the ofteneft: next, o, then a, and i; but u, and y, are not fo often uſed as fome of the confonants. Among the vowels, e and o are often doubled; the reft fcarce ever: and e, and y, often terminate words, but y is lefs frequent, and confequently eafily diftinguiſhed. To find out one confonant from ano- ther, you muſt alfo obferve their fre- quency, [ 25 ] 1. quency, d, h, n, r, s, t, and next to thofe, c, f, g, l, m, w, in a third rank. may be placed; b, k, p, and laftly q, x, z. This remark, however, belongs to English; for in Latin the confonants are 1, r, s, t; next, c. f, m, n; then, d, g, h, p, q; and laftly, b, x, z. But the firft dif- ficulty is to come at the knowledge of three or four letters, therefore where a word of four letters hath the firft and fourth the fame, it is moft likely to be that; to prove which look for another of four letters, beginning with the two firft, and ending with two others, and it will probably prove to be this; and more efpecially if you find another with three letters, beginning with the firft two, for in that cafe it muſt be the; now having found out in any part of the Cypher theſe three words (that) (this) and (the) place them over the characters which you know to be t, h, a, in s, en and then confider what letters are defi- cient, and what the words, from the num- ber of letters which compofe them, are moft [ 26 ] moft likely to be; and you will find fuch ready and ſurpriſing intimation from the above fix deferters you have apprehended, that you will foon be in poffeffion of the whole battalion. Where words of two letters appear of the fame characters, differently placed, it is moft likely one is on, the the other n o, fo o f, and for, and from, difcover and convict each other; and t h are very often ufed in the beginning of English words, as, the, that, this, them, thefe, their, thrust, thwart, &c. &c. TH CHAPTER II. HE Earl of Argyle's method of confounding the fenfe of his letter by altering the place of the words, was at that time thought inexplicable; and I have ſeen many methods laid down to explain it; but the readieft way is to mark the concurrence of PROPER words, I [ 27 ] 1 know not the ground's our friends have gone upon which hath occafioned them to offer fo little money as I hear neither know I what affiftance they do intend to give and 'till I know doth I will neither refufe my fervice nor do fo much 23 object against any thing is refolved 'till I firft hear what Mr. red or any you fend fhall fay only in the other mean time I refolve to let you know as much of the grounds I go on as is poffible at this diſtance and in this way I did truly in my the very leaft fum I propofition mention thought could do our bufinefs effectually not would bave thought requifite in half of what I an other jun&ture, &c. WHEN Argyle had writ a letter thus, of which the above is a part of one, he filled up the ſpaces with any words which occurred, and then it appeared thus: [ 28 ] I gone fo I and refufe object first you time much is way the our would have bufi- nefs very I poffible of I fend here against my 'till what little upon KNOW NOT which money affiftance I fervice any what shall re- folve THE at did leaft effectually thought requifite not fum truly this GROUNDS to fay Mr. thing nor know they as hath grounds occafioned I do both do is red only let I dif- tance in I half in an of thought my and go you in or refolved fo I intend he or them OUR FRIENDS, &c. &c. &c. Now as I obferved above, mark but the concurrence of proper words, and ef- pecially if they be at equal diftances (and fo his letter is writ) then the num- ber of words between thefe is the co- lumn; and thus the bufinefs is done; there may indeed be a proper coinci- dence by chance, but if you lay hold of fuch only as are equidiftant; they muſt develope the matter where the writer goes down one column and up another. And this is a much readier and certain method, than that laid down by Falconer. THE [ 29 ] THE immortal Lord Bacon, the great- eft man Britain, or perhaps any other nation, ever produced, has given us a fecret way of correfpondence, and to di- vert fufpicion, by inferting of nulls; he fays, "As for the fhifting of examina- "tion, there is ready prepared a new "and profitable invention to this pur- 66 pofe, which feeing it is eafily procured, "to what end fhould we report it as de- "ficient? The invention is this: that "you have too fets of alphabets, one "of true letters, the other of non-figni- "ficants; and that you likewife fold up "two letters, one of which may carry "the fecret, another, fuch as is probable "the writer might fend, yet without "peril: now if the meffenger be ſtrictly "examined concerning the Cypher, let "him prefent the alphabet of nonfigni- "ficants, for true letters; but the alpha- "bet of true letters for non-fignificants: 66 by this art, the examiner, falling upon "the exterior letter, and finding it pro- bable, fhall fufpect nothing of the in- << terior letter. THE 11 9" [ 30 ] THE publication of this art, in fome meaſure defeated the ufe of it, but yet, without any alphabet, fuch writing is decypherable, for if two alphabets are ufed, the number of characters will fhew it. Trithemius, in his letters to Arnoldus Bofticus, mentions fo many extraordi- nary methods of fecret information, that Frederick the 2d Prince Pala- tine, caufed his original M. S. to be burnt, and lucky it was, in thofe days, that the author did not burn with them; and yet, thofe wonderful propofals Trithemius aftonished the world with might be performed without any of thofe fupernatural affiftances he was fuppofed to command. He informs Bofticus that his firft book contains more than an hundred ways of fecret writing, without fufpicion, and without any tranfpofition of the letters; and that no man by human induftry, can know, or even fufpect, the enveloped meaning of his letters, without being taught the art by [ 31 ] by him. Notwithſtanding thefe bold Un- affertions, I am convinced that an or- dinary capacity in thefe days, who had a little confidered the matter, would foon have convinced him of his error. couth hard words were chiefly what he ufed to diſguiſe his meaning: indeed he alfo afferted, that he could convey in- formation by fire to any one inftructed in his art, at an hundred miles diſtance; and that part of his art might, in the opinion of the Prince Palatine, be confi- dered more wonderful than any, and de- termine him to burn his books of witch- craft. Yet, in war time, this manner of correfpondence, is practifed every night by the Spaniards at St. Roak (a high fituation near Gibraltar) to inform the Governor of Cadiz, not only of the number of men of war lying at anchor in the bay of Gibraltar, but what number have failed either out of the bay, up the Mediterranean, or out of the Streights mouth. I believe, indeed, they went no farther than this; but they might, by the [ 32 ] the fame rule, have informed the Go- vernor of Cadiz, that General Hargrave was more intent on getting money, than on defeating their intelligence; for had the General caufed the fame fort of lights to have been exhibited from the fignal houfe on the top of Gibraltar hill, at the fame time that the Spaniards fhewed theirs, their method would have been ut- terly diſconcerted: and yet aftoniſhing to believe it! this has been a conftant UNINTERRUPTED practice of the Spani- ards, during every war, fince the Engliſh have been in poffeffion of that important place! Indeed the Governor may fay, What have I to do with the number of fhips in the bay, or with marine affairs? and it is more than probable that an Admiral, who commands a fleet there, might quarrel with the Governor for meddling with his department! and yet poor ENGLAND abounds with fuch Generals, and fuch Admirals too. But had Marshal Saxe, or Lord George Germaine, been Gover- nor of Gibraltar at thofe times, I am con- [33] convinced the Spaniards at Cadiz would have had no information from St. Roak, but what was conveyed by an ordinary meffenger, or by exprefs. They are fo aware of being defeated, by fhewing the SAME number of lights, as there are King's fhips in the bay, that there is no forming any judgement by that; but by taking down conftantly every night, for fome weeks together, the lights they did fhew, and the diftance of time between each light, or lights, I was convinced they thereby reprefented the alphabet, and that they conveyed their information by letters of fire: indeed I had in fome mea- fure acquired their method, but not un- derſtanding Spanish, and fearing a court martial and a Cafhierment, if I had in- formed the Governor of my difcovery, I have referved it to this hour of fafety, being, thank God, out of the reach of every fpecies of ignorance and incapacity, but that of my own; for I do infift upon it, that a Governor fo ignorant or indolent as not to defeat fuch a kind of corref- C pondence, [ 34 ] pondence, would be wicked, or foolish enough, to puniſh any officer who prefumed to dictate to him! THESpaniards by thofe lights not only ex- preffed letters, but figures alfo; fowhen they only meant to ſpecify the number of men of war in the bay, two lights might fignify the No. X, four XX, &c. The failing of the whole fleet out of the ftreights mouth, might be fhewn by one continued fire burn- ing, as I have often feen it, for fome time together; and up the Mediterranean, by two fires: yet every information of this kind may be defeated, and even falſe alarms given to the Spaniards at Cadiz, by a Governor, who would take half the trouble to ferve his country, which he does to enrich himſelf, and diftreſs thoſe under his command; for the worſt civil government, is infinitely fuperior, to moſt called military. I have known a Gover- nor of Gibraltar, fend a Genoefe in war time over to the Spanish fide, to buy him fome potatoes, which the Spaniards had taken in an [ 35 ] an Irish veffel, and hang the poor Genoefe, without trial, when he returned, for a crime the man could not have been guilty of, had not the Governor, by fending him there, led him into it. After having ex- plained this matter, and fhewn how eafily the Spaniards may, for the future, be dif- concerted in this particular inftance, I am afraid I have done them an effential piece of fervice; for tho' I can eafily fuppofe that 'e're long General Elliot may become the Governor of Gibraltar; yet I am con- vinced he is too wife, and too great a man, to regard what I may fay upon this, as little, as what I have faid to him, upon a former occafion. Trithemius goes further in the art of fe- cret information, than any other has yet pretended to; for he afferts he can convey his fentiments at pleaſure, to a clofe pri- foner three miles under ground, tho' he be kept in the ftricteft cuftody. Schottus, and many others, have em- ployed much unneceffary time to difcover C 2 by [36] 11 by what means fuch information could be conveyed to a man under ground! but if it can be done, it muſt be effected by cer- tain founds made in, or upon, the earth above; but it is moft likely his words are enigmatically propofed, and therefore al- lowance must be given for that; indeed it is likely, Trithemius might think it practicable by magnetic powers; for it has been faid, that two needles touched by the fame loadſtone, and moving like the mariner's compafs in a circle, wherein the letters of the alphabet are defcribed, would fympathife with each other, at however great a diſtance they were; but this, Schottus, and other naturalifts, have clearly demonftrated, to be impracti- cable at a greater diftance, than a few feet afunder. THE firft and chief art of fecret inti- mation in theſe days, is, to prevent fufpi- cion, as fcarce any kind of correfpondence can be carried on by cypher, but what may be unfolded without the key: a meffage may be conveyed by a piece of fewing [ 37 ] fewing thread tied full of knots, and that twiſted about a ſmall parcel, fent to the confederate, as I fhall fhew hereafter; fo likewife by mufical notes, both which methods are mentioned by Biſhop Wil- kins; but then a maſter of mufic might contrive fo to write by mufical notes, that they fhall not only convey the harmony, but the words alto. Bishop Wilkins has given a fmall fpecimen of writing by mufical notes; but the want of time, and harmony to them, would create fufpicion, and that would foon produce a diſcovery. THE manner of fecret information by a knotted thread, or by marking a white thread with ink, I have carried on a cor- refpondence with; and it is to be done by the following method, which I mention as the moſt fimple, for it may be greatly im- proved.---Take two pieces of wood like a flat ruler, a foot or more long, and an inch broad, divide, from within about a quarter of an inch of each end, the ruler into twenty-four equal diſtances, and on C 3 thefe [ 38 ] thefe write, as in the plate annexed the twenty-four letters; then fix two large pins in the hole which is to the left of a, and on the right of z, and tie a noofe in the end of the ftring, and hitch it over the pin near a. Now, if you would fig- nify, Fly, we are no longer fafe, do it thus:---Bring the thread on from the right hand pin, and over the letter f, either tie a knot, or black it with ink; then mark a knot at l, and then aty; here the firft word is taken without a return of the ftring, fo continue to wind round the thread, and mark down the letters, 'till the fenfe is compleat. Your confe- derate muſt have a rule of the fame length and divifion, and upon receiving the ftring, he winds off the letters, mark- ing them down as his ruler picks them up; but if the knotted ftring be once fuf- pected to convey any private intimation, a decypherer will find no difficulty in making out the fenfe it conveys, by re- ducing the knots into an alphabet of his Own [ 39 ] own, by taking all the feveral diftances between the knots, or other marks of dif- tinction, or between a few of them, if the thread be long. This alfo is men- tioned by Bishop Wilkins, and is to my certain knowledge practicable, as well as decypherable; for a gentleman of Har- wich, a few years fince, fent me a knotted thread, encloſed in a paper, without any key or clue, than letting me underſtand, it conveyed fome fort of information; and and I foon difcovered, it was to let me know, that one of the packets which go between that town and Holland, was caft away, upon the Dutch coaft. BISHOP Wilkins, in his fecret and fwift meffenger, fays, It is very obfervable what Vallefius relates of Pet. Pontius, who, by an unheard of art, taught the deaf to ſpeak; firft teaching them to 'write the name of any thing he ſhould point to, and afterwards provoking them to fuch motions of the tongue, as might anſwer the feveral words: and, it is probable,' fays the Bishop, that this invention, well followed, might 6 C be [ 40 ] be of fingular ufe, to thoſe who ſtand in need of fuch helps, though certainly that was far beyond it (if true) which is related of an ancient Doctor Gabriel Neale, that he could underſtand every word, by the meer motion of the lips, without any utterance.' But it is im- poffible that fhould be done, with any degree of certainty, for the VISIBLE MO- tion is often the fame, in the uttering different letters and words, as b and p; pronounce, mutton, and butter, and you will find the lips have exactly the fame motion; and that the difference in found arifes, from the breath paffing through the nofe, in the former, and through the lips in the latter; and found is what no eye can perceive; and confequently, it is impoffible, to teach one born deaf to fpeak, though they may be taught, to write. I have feen a lady, who was born deaf, write down in her common place- book, upon the entrance of a grey eyed ftranger, who vifited the family,---- Puppies Eyes; and having mentioned the teaching a deaf perfon to read and write, it [ 41 ] it may not be improper to inform thofe, who by age or accident have loft their fight, how they may be able nevertheleſs to write very diftinctly. Let any com- mon joiner make a flat board, about fourteen inches long and twelve wide, in the middle of which let a place be funk deep enough, when lined with cloth, to hold only, two or three fheets of fool's- cap paper, which muft quite fill up the ſpace; over this muſt be fixed a very thin falfe frame, which is to cover all but the paper, and faſtened on by four little pins, fixed into the lower board: and acroſs the lower frame, juft over the paper, muft be a little flider, an inch and a half broad, which must flip down into fe- veral receffes made in the upper frame, at proper diftances for the lines, which ſhould be near an inch afunder; and this ruler, on which the writer is to reft his fourth and little finger, muft be made full of little notches, at a quarter of an inch diftance from each other; and thefe notches will inform the writer, by his little finger dropping from notch, to notch, [ 42 ] * notch, how to avoid, running one letter into another. When he comes to the end of the line, he muft move his flider down to the next groove, which may eafily be fo contrived with a fpring, to give warn- ing, that it is properly removed to the fecond line, and fo on. I would not, by this hint, to inftruct the blind to write, have it understood, that I mean to dif- credit Mr. Pinchbeck's Nocturnal Remem- brancer, or that I took the hint from that ufeful Toy, having above twenty years ago, affifted a gentleman, then, and now living at Southampton, with fuch an apparatus for writing as defcribed above. Nor would I have it fuppofed, that like the man who afking the ufe of fpectacles, and on being told they were to read with, was furpriſed that he could not, by applying them to his nofe, as others did, make out a fingle word, 'till the optician's amaze- ment produced the following pertinent queftion, Whether he ever could read without fpectacles? The writer muft ufe a fountain pen. Bath Transactions Saunderson Persian Prince CHAP. [ 43 ] bid BIS C C CHAPTER III. ISHOP WILKINS, in his chapter relative to a language confifting of tunes and mufical notes, without any ar- ticulate found, fays, "If the mufical in- ftrument that is ufed to this purpoſe, be able to exprefs the ordinary notes, not only according to their different tones, but their times alfo, then may each let- ter of the alphabet be rendered by a fin- gle found, whence it will follow, that a man may frame a language, confifting only of tunes, and fuch inarticulate founds, as no letters can exprefs, which kind of fpeech, is fancied to be ufual amongst the lunary inhabitants; who, as Domingo Gonfales hath difcovered, have contrived the letters of the alphabet upon the notes after fome fuch order." But the fpecimen the Bishop has given by writing GLORIA DEO SOLI by minums, on mufical lines, will inftantly appear to any SGREEN J. LATRASH [ 44 ] any one, the leaft converfant with mufic; that being without harmony or time, it muſt have no meaning, or that fome hid- den matter is thereby difguifed. I fhall therefore endeavour to write down an al- phabet by mufical notes, in fuch a manner, that even a maſter of mufic fhall not fuf- pect it is to convey any meaning, but that which is obvious; and I am perfuaded an alphabet of mufical notes may be fo con- trived, that the notes fhall not only con- vey the harmony, but the very words of the fong, fo that a mufic-mafter (which is too often his defign) may in- ftruct his female pupil, not only how to play upon an inftrument, but how to play the fool at the fame time, and im- pofe upon her parents or guardians, by hearkening to his folly, impertinence, or wickedness. When a mufick-mafter has once taught his female pupil to un- derſtand a mufical alphabet, and the will permit him to carry on a fecret correfpon- dence, he may fend her daily, a leffon which fhe may repent having learnt, as long as the lives. IN [ 45 ] In the plate annexed, I have given a mufical alphabet, and under it a fpecimen to explain more fully my meaning. If a mufick-mafter be required to play it, he will certainly think it an odd, as well as a very indifferent, compofition; but nei- ther he, or any other perfon, will fufpect that the notes convey alſo the two follow- ing harmonious lines from Dr. Goldfmith's 79 Poem, The Deferted Village. "Near yonder cops where once the garden fmil'd, "And ſtill where many a garden-flower grows wild." Now it may be fo ordered, that the plain notes, i. e. the crotchets and mi- nums alone, compofe the alphabet, and that neither flatts nor fharps, nor the fmaller notes between, (which may be placed as mere graces, and meant to deceive) have any thing to do with the reading; fo that the Decy- pherer would not fo readily know how to proceed, and many people there are, who will think it impoffible to be made out without the key; yet I am per- fuaded, [ 46 ] fuaded, one who poffeffes a very mode- rate turn for fuch bufinefs, would read it in a very fhort time. Ir the words of a fong, could be thus conveyed by the notes, as well as the air, it would, exclufive of the contrivance, be of infinite fervice and eafe, to ladies who fing: indeed it ſeems, to thofe who are not acquainted with mufic, almoft inconceiv- able, how a perfon at firft fight, fhall be able to read the bafs and trebble cliff, together with the words, and play two parts, and fing one, at the fame time. It is certain that two muficians might, by a very little application, carry on a corref- pondence with their inftruments: they are all in poffeffion of the feven notes, which exprefs a, b, c, d, e, f, g; and know by ear exactly, when either of thoſe notes are toned; and they are only to fet- tle a correfpondence of tones, for the re- maining part of the alphabet; and thus a little practice, might enable two fiddlers to carry on a correfpondence, which would greatly aftonifh thoſe who did not know how [ 47 ] how the matter was conducted. Indeed this is no more, than what is called dactylogy, or talking on the fingers, which I have feen done, and underſtood as quick, and readily almoft, as common conver- fation. THOSE who are acquainted with Lord Bacon's great depth of capacity, will readily agree with me, that a fecret method of writing contrived by a man of his amaz- ing penetration, muſt be fuperior to all others, as indeed it is, and contains the higheſt degree of Cypher. I fhall there- fore lay before the reader his invention of writing. OMNIA PER OMNIA FOR performing this, you must have a bi-literary alphabet, and a bi-formed alphabet; then write down the fecret mef- fage on a paper a-part; you are to fuppofe that all the letters in the firſt alphabet ex- prefs a, and thofe in the ſecond b; to the interior letter, which Lord Bacon calls bi-literate, you fhall fit a bi-formed ex- terior letter, which fhall anfwer the other, letter [ 48 ] letter for letter; and afterwards fet it down.

IN the above Cypher it is to be cb- ferved, that the outward writing muft bear a quintuple proportion to the inward. Therefore to decypher the above, you muft firft find out whether two or three alphabets are uſed, and this will be dif- covered by the different kinds of letters which compofe the outward writing; fuppofe one alphabet to be a, the other b, and the third c, then take out the three letters as if they only were inferted, and then it falls under the fame method of decyphering it, as the firft fpecimen I D have [ 50 ] 9 have given, for it is nothing to the pur- pofe, whether your fuppofitions and the writer's, be the fame or not; for if you fuppofe always an a for his b, the opera- tion will be equally the fame. I cannot here quit my Lord Bacon, without making one remark, which, though it is painful to reflect on, and indeed reflects a little on his memory, yet it is too true and ftriking a proof, of his not being above practiſing thofe arts, which moft lawyers make ufe of. The above method of fecret writing is cer- tainly the moft ingenious of any ever invented, and yet it was invented and published too, by that great man: what then muſt we think of him, who, when Attorney General, at the tryal of the Earl of Somerfet, mentions this kind of fecret writing as an aggravation of the Earl's crime, concerning the poifoning of Sir Thomas Overbury? where, fpeaking of the Earl's former intimacy with Sir Thomas, Nay, (fays he) they were grown to fuch an inwardness, as they ' • had [ 51 ] had Cyphers and fargons for the King and Queen, and all the great men ;' things feldom ufed, but either by Princes and their Embaffadors, and Minifters, or by fuch as work or practice againft, or at leaft upon, Princes.' But may it not be neceffary, that every means, by which a fecret correfpondence can be carried on, fhould be publifhed, provided there is at the fame time a clue given, how to come at it? For no man, however expert he may be in other matters, can readily fet about reading a letter, written in Cypher, who has not previouſly confidered the matter; yet I muft confefs, most authors, who have writ upon this fubject, except Biſhop Wilkins (who was a very good man) have acknowledged, that the pub- liſhing fuch an art, would be detrimental to the public. And Trithemius thought it neceffary to make an apology for printing his fix books of Polygraphy: but, on the other hand, let it be confi- dered, of what importance to a ftate it may be, to have more than ONE MAN D 2 able 14 [ 52 ] able, upon any urgent occafion, to read letters written in Cypher. THERE were infinite pains taken, much time loft, and perhaps the life of a King too, for want of a ready decypherer of thofe letters writ by the Earl of Argyle, during the confpiracies carried on in Scotland; and yet one of thofe letters, of which a part is given above, and which occafioned fo much pains and lofs of time to unriddle, would now be reduced to the true fenfe, in a very few hours; not becauſe men are now more wife, but be- caufe more men have of late confidered the matter thoroughly. Indeed I am of laid open opinion, that the fon of a decypherer, bee, ibis even untaught, will more readily ac- quire his father's art, than the fon of any other man, of equal abilities; and if this be true, no cenfure can juftly fall on the Biſhop of Bath and Wells, for pro- curing the reverfion of his employment to his fon. THAT in general, the fon of a mufi- cian, exclufive of the advantage he has of [53] of an able mafter at hand, will learn to play on any inftrument, at a younger age than other children, I have known many inſtances of. There is a profeffor of mufick now living, who, when a very little boy, and not much bigger than the fiddle he played upon, aftonifhed me fo much, when I first heard him, that I could not help faying, I was certain his father was by profeffion a muſician; --he was fo; but I was at the fame time af- fured, that he never took any pains to teach his fon, and the boy, befide play- ing well on the fiddle, accompanied it by whiſtling through his teeth (a practice entirely his own) fo that his fiddle and whistle together, was quite equal, to moft fiddles accompanied with a tabor and pipe! and the genius of the offspring for the particular profeffion of the father, is not only to be obferved amongst the human fpecies, but in brutes alfo. I had once a Newfoundland dog, who hav- ing his early education on board of a man of war, was there taught to do D 3 many [ 54 ] many things, which I will not venture here to relate, and only obferve, that a puppy, which he produced even from a a greyhound bitch, inherited many of his tricks untaught. Heretofore a cri- minal convict who could read and write, faved his life: but I apprehend the art is now too common, and that it occafions many to lofe their lives, by having been taught writing, and reading, inftead of ploughing, and fowing. Bifhop Wilkins tells a pleaſant ſtory of a negro flave, who being fent with a letter and a baſket of figs, and the flave's aftoniſhment, when he found, that the letter informed the perfon to whom they were fent, that he had eat a part of them on the way; and who, upon a future occafion, hid the letter under a ſtone while he purloined the prefent, with no better fuccefs: and I have myſelf heard a negro fay, with aftoniſhment, That *Becerara make pen, and pen make paper talk! and this puts * A white man. me [ 55 ] me in mind of a fmart reply, made by a little negro boy to his mafter, who, find- ing him a child of good parts, frequently converfed familiarly with him; but yet when he committed a fault, gave him a note to carry to the overfeer of his plantation, directing therein, that he fhould be whipped. The boy perceiv- ing the conftant and fatal confequence of carrying a bit of paper to the overfeer, took a favourable occafion to question his mafter about it; and why, when he carried a bit of paper, and at no other time, the over- feer treated him with fuch feverity? The mafter then informed him, that the pa- per talked fo, and fo, to the overfeer, be- caufe he was idle, and neglected his work; why mafter, faid he, I never fee you work !---no, not with my hands, it is true, faid the mafter; but I work with my head, which is much more la- borious work than yours. So the next time the boy was fent with a paper to the overfeer, he threw it away, and being afked by his mafter, what the overfeer faid [ 56 ] faid to him? Nothing, replied the boy, for I did not go to him, having this time worked with my head too. But to re- turn to the matter of fecret writing, and the art of difclofing it. Now having given the most difficult method, i. e. of Lord Bacon's writing omnia per omnia, I fhall only briefly mention a few others, treated of by Bifhop Wilkins, Falconer, Schottus, &c. many of which may be almoft as foon read as written. vo CHAPTER IV. ONE NE very ingenious method which Schottus faid he had from Count Gonsfield is, what would fruftrate the method given of decyphering above. This is done by difpofing the letters of the alphabet in a line or a circle, over which they place any number of figures in this manner : 436 abcdefghiklmnopqrftu wxyz You then write the fecret intention on a paper, and over the top of the let- 7911am aid yd be ters [ 57 ] ters place the number of figures agreed on, let the words be thefe: The Governor of the city is beyond cor- ruption, fo that we may conclude there is nothing of bribery will ferve the turn. Which words, according to the ex- ample will ſtand thus: 436 43643643 64 364 3643 64 The Governor of the city is 364364 3643643643 64 3643 64 364 beyond corruption, fo that we may 36436436 43643 64 3643643 64 364- conclude, there is nothing of bri- 36436 4364 36436 436 4364. bery will ferve the turn. OBSERVE what figure ftands over the the first letter of the writing, viz. T, with the figure 4, then count forward as many letters, and write down the fourth, which from t will be x; then fee what figure will be over the fecond letter h, which is figure 3; count forward from h three, and it will be k; then write down the fixth letter from e, and it will be k alfo; and fo proceed, always ob- ferving, [ 58 ] ferving, that the letters in the writing, are fecretly communicative, to the figures above it, until you come to the end of the epiftle, which will then ftand thus: Xkk kqahtfrt ti wnh eoxa ow dkbqfg etvtafworp yr wndw bh ofb etqegyfk xkkug ow ptxkoqui ti dxmdkvlk zlqo vkvxk xkk xxxq. To decypher this, tranfcribe the Cy- pher out of the epiftle, keeping the lines and letters at fuch a distance, that you may place over each, a figure above it; then endeavour to find out the number of figures in the key, which must be en- quired into by feveral fuppofitions. Suppofe the number of figures to be three, then place them above the Cypher in this order. 123 12312312 3I xkk kqahtfrt ti, &c. &c. Now obferve, where the fame characters and the fame figures happen to fall toge- ther, and you will find, that it expreffeth the fame power, as in the example, and that k, with the figure 3 placed over it, has the power of e, through the whole writ- ing; [ 59 ] ing; and that x, with the figure i over it, fignifies t; but the fame letter, when its figure is altered, cannot exprefs the fame power, for q, with 2, r, with 1, and t with 3, exprefs feverally, o, in the writing. Therefore, one and the fame letter, will be expreffed by dif- ferent characters, fo contrary to the first Cypher, laid down in the former part of this treatife; for here you will find, as in the first word of the above Cypher, that k not only ſtands for h, but e alfo, fo that you may be certain when any character is double in a writing of this nature; different characters, are expreffed by that letter. Having made thefe, and other general remarks, proceed to difco- ver particular fyllables or words, and having got one, you will foon find, with it, the true numbers that are contained in the key, or at leaft fome of them, which will help you to the reft, obferving, that in your ſeveral operations, you muſt count the letters backwards; fince in general, the Cypher is written forwards; yet, [ 60 ] yet, as I have remarked above, both ways fhould be tried. 3d es sodingh BISHOP WILKINS obferves, that the difference of characters in the world, is part of the general curfe upon their once one tongue; and from the fame reafon we may infer, that the different methods of writing thofe characters are fo too. THE Oriental languages are writ from the right hand to the left only; the Ethiopic and Armenian proceed as ours do, from the left to right, as well as Greek, Latin, French, Spanish, and German. At first the Greeks writ from the left hand to the right, and then from the right to the left, forward and back- ward as the ground is ploughed; fo that an epiftle fo writ, might perplex a little, a fpecimen of which is given by Biſhop Wilkins, thus: smol flest to 10 yea 2001 T [ 61 ] Til W h t 1 S e S e u CECTC eld fr e f 0 0 tei hh u uf 1 toh p a o t 1 ot tha p e h t n u P h n t e tdc f f 1 fo r go 1 t d e n n 1 e i id f a O f i e c 1 c obfw f y f m t a i e pd e n e a be ege e HERE the reader muft begin at the first letter t, and take the letters down from the top to the bottom, and then go up the next row, and fo on, and he will find the reading to be, The peftilence doth ftill encreafe amongst us; we fhall not be able to hold out the fiege without fresh and Speedy fupply. This is faid to be the practice of the Chineſe. I have obferved above, that a long letter writ in cypher is eafier made out than a few words only, and this arifes from the frequency of the vowels, and the repetition of the fame words, there- fore a fentence contrived wherein the feweſt letters are employed, will be the moft [ 62 ] moft difficult to read, as the following ſpecimen will evince, which is compoſed of only one third part of the alphabet, and writ according to Cafar's method, taking the b for a, the c for b, and fo on. bcdefghiklmnopqrftu wxyz X abcdefghiklmnopqrftuwxyz h, untke, he, h, dnwke, aws, h, dnwke, mns, boc, he, he, dnwke, mns, gnx, dnwke, h, h, dnwke, mns, xhsinwu, h, dnwke, dnwke, h, dnwke znw? THE reader will obferve, that in the above cypher, there are two fingle cha- racters together, as h, h, and that there is a repetition of a word of five letters d,n,w,k,e, i. e. the fame word repeated twice together, yet if he will be at the pains to pick it out from the alphabet above, it will appear to be a jingle of words, which however is fenfe, if it be not good grammar. I have ſeen a very ingenious method of fecret information, which was by a let- ter delivered open to a perfon, who Hom was [ 63 ] was going abroad, and which appeared to him, as it would to every common reader, to be the warmeft recommenda- tion of the bearer to the writer's friend and correfpondent that could be; yet, at the fame time, the real intention of the writer was, to caution his friend againſt having any connection with him, as he was the moft wicked and dangerous man he ever knew. The following let- ter will fhew how the other was contrived, but is infinitely inferior, as it is, in many places, fo lame, as to create fufpicion; and fufpicion alone is fufficient to produce the true meaning: but the other letter I have feen, had none of thefe imper- fections, but was writ throughout, in an eafy, familiar, and natural ftyle. THE paper being doubled in the mid- dle, the real epiftle is writ on the left hand fide thus: THE defign is not fecret; there is now no fafety but by flight; do not fail to meet me half an hour hence; let the next meeting be juft [ 64 ] juft without the gate; (if my fenfes are found) we may conclude to have infallible evidence the fnare is prepared effectually to entrap you and yours, &c. P. S. Prithee ex- pofe not thyſelf to imminent danger. grion she The manner of concealing it thus. The defign is not in danger to all it is as yet fecret; there is now no thing in view to threaten our fafety but by flight; we fhould ruin all our defigns. do not fail to meet me by fix in the old manner; in half an hour hence; I intend to be at the confult, let the next meeting be where they will, I'll have notice juft without the gate; was the Governor this morning (if my fenfes are found) fecure as we could with him we may conclude to have hit right on the means and more infallible evidence not on this fide conjunction, the fnare is prepared they are mifted and fee that it is effectually to entrap them and on their ruin to raiſe you and yours, &c. P. S. Prithee throw off thofe vain fears; expofe not thyfelf to fcorn when there is not any imminent danger. THE [ 65 ] WRITING, in the above manner, was practifed by the Roman Senators, and other great men among them, who being fo frequently importuned to write in favor of thoſe whom they knew nothing of, agreed amongſt themſelves, upon fome fecret intimation, that what they writ, and what they meant, were frequently very different. From this practice the proverb De me- liori nota commendare, arofe; and fome- thing like this, I think, is known amongſt us at this day, as written with, or without, Court favor! UPON the fubject of fecret informa- tion by figns, or geftures, without the help of words, or letters; I fhall here infert what Lord Bacon fays. It is cer- tain, fays he, that "whatſoever may be 66 diftinguiſhed into differences, fufficient "for number, to exprefs the variety of "notions (fo thofe differences be per- ceptible to fenfe) may be the convoy "of the cogitation, from man to man;" 66 E and [66] and foon after he adds, NOTES therefore of things, which without the mediation of words (OR LETTERS) fignify THINGS, are of two forts; whereof the firft is fignificant ex CONGRUO, and the other ad PLACITUM: and the fame noble au- thor, fpeaking of tranfitory figns of in- formation, fays, "As for geftures, they are, as it were, tranfitory Hieroglyphics; for as words pronounced vanifh, writ- ings remain; fo hieroglyphics, expreffed by geſtures, are tranfient; but painted, permanent; as when Periander being confulted with how to preferve a tyranny, he bid the meffenger ftand ftill, and walking in his garden, top'd all the highest flowers," the meaning of which was, the taking off the heads of moſt of the nobility and keeping the others low. Schottus demonftrates how a man may, by ufing words that are infignificant to the confederates, guard thofe which are to be fecret, from fufpicion; which he clearly fhews by the following example. SUPPOSE [ 67 ] SUPPOSE the fecret intention is to warn the confederates of danger, and to adviſe them to eſcape, and the words theſe, Sumus in periculo; cavete The harrangue thus: In manu DEI fumus ubicunque verfamur hanc ob caufam NOS in rebus adverfis nequaquam pufillanimes effe debemus; quo- niam DEUS periculo omni eripere poteft. Ergo AUDITORES cavete peccata & curam rerum veftrarum permittile DEO, &c. OBSERVE here, that the words which exprefs animate beings, hint to the Con- federates, that they precede the words which are to convey the fecret informa- tion, as DEI, NOS, DEUS, AUDITORES, and the words which follow them are fumus in periculo; cavete. FALCONER gives a fpecimen of this method in Engliſh thus--- SUPPOSE the words to be communi- cated were Fly, you are difcovered. E 2 THE [ 68 ] THE difcourfe may be to this effect: let every MAN fly to his duty. GENTLE-- MEN you now fee what PEOPLE are, and may do in their madnefs: but we dif covered long fince their folly, &c. THE words that point out the fecret meaning are, MAN, GENTLEMAN, PEOPLE, WE; and taking the four words which immediately follow them, the confede- rates are told to fly, for they are difco- vered. Now the fame method may be followed in carrying on a fecret corref- pondence by mufical notes, or by com- municating the words of a fong, by the fame vehicle, which points out the time and harmony, and this may be done (without having any knowledge of mufical compofitions) but by any common piece of mufic whatever: to do this an alphabet muſt be formed as in the plate annexed; or in any other manner, for it may be con- trived much better for the purpoſe: then take any piece of mufic (but fuch as is com- [ 69 ] compofed of the greateft variety of notes will be beft) and copy it out upon ruled mufic paper, leaving one row of blank lines between; i. e. thofe lines on which the fecond or bafs is ufually writ. When you have copied the whole out, draw ftraight lines on the bafs cliff, exactly under thofe, which divide the time in the trebble. Suppofe you would write, My time O ye mufes, &c. look for the note which is m in your alphabet, and then for y; now fuppofe there are eight or ten notes between the m and the y, then thofe are to be marked as nulls on the bafs cliff, juft under each note, by that mark, which in mufic imports a reft, which is this 1, and the confederate who has the key, knowing that the reft- notes are nulls, only makes ufe of thoſe which are open, or which may be pointed out, by inferting other notes ex- actly under them in the baſs cliff, and if the under notes, are placed three notes Power on the lines, than thofe in the trebble E 3 are, [70] are, they will in that cafe be in harmony, and the refts between, being in fuch an order, will prevent any fufpicion, except to thofe who underftand mufic; and yet even thoſe who do, would hardly fufpect that the notes of Lady Coventry's minuet, implied, as it might, an affignation in Grofvenor-fquare; or, inftead of the reſts being under the nulls, as they will of courſe be very frequent, they might be placed only under thofe notes which con- vey the reading, and then the bafs cliff would appear as bufy as the trebble, and tend the more to perplex the decypherer, as he could not be fure, but both lines were employed to conceal the private writing: indeed where letters fall very diftant from each other in the trebble, it might be fupplied, and fre- quently too, on the bafs cliff, and figni- fied by a dot, or fome other mufical cha- racter, placed near the trebble note immediately above it. A letter thus writ in Cypher, would dif- [ 71 ] difconcert even a good Decypherer, and throw him out of the methodical way, of coming at the fecret contents; indeed I rather think, it must be come at, more from ingenuity, than method. THIS however is a hint only, how this kind of Cypher may be compleatly made ufe of, than a perfect method; but I am perfuaded that a good com- pofer of mufick, would be able to write any common epiftle, with the affiftance of the trebble and bafs cliff, fo as to have very few null-notes; and the fecret meaning inftantly obtained by thofe who are in poffeffion of the harmonic alpha- bet. Or, fuppofe every crochet or minum, which is to expreſs a letter, is writ with the tail of the note downwards, and all the nulls upwards: this indeed might occafion fome awkwardnefs in the ap- pearance of the mufic, but it would not tend at all to a difcovery, but ftill, what I think practicable is, that an harmonic alphabet may be fo contrived by a good com- [72] compofer of mufic, that every note fhall be expreffive of a letter, and convey the words of the fong as perfectly to the eye, as they do the harmony to the ear. The compofer of an harmonic alphabet, fhould be careful to include thofe notes, which are most frequently ufed, into his alphabet; and thofe, I think, are on, or between, the five ruled mufic lines; but he muſt carefully avoid having any of thoſe notes already fo well known to exprefs a, b, c, d, e, f, g, keeping their proper place, for that would be the first confideration of an ingenious Decypherer. Now if this art of writing fecretly by mufical notes, was to be practiced, I queſtion whether a Decypherer, to be expert in his art, muft not only be a maſter of languages, but even a difciple of Apollo. However, according to the mufical al- phabet annexed, provided a letter is writ by it, and the active notes well corded between with nulls, upon the fame lines, which [ 73 ] which might be known to be fuch, by the tail being turned up or down, or characterised by the mark for a beat, a fhake, a trill, a paufe, a flatt, or a fharp; it would be ſcarce poffible for a Decy- pherer to make out, with certainty, the fenfe; and this method unpublished, would be leaft liable to fufpicion; for who, that examined a fufpected meffenger, would think an old fong, without words, in which perhaps the meffenger's tobacco or fnuff might be put, contained the fecret he was to convey? nor could an ordinary meffenger, either by bribes or threats, dif- cover any thing more, than that the bearer was ſtrictly charged to deliver that piece //79 of mufic, into which he put his tobacco, to fuch a particular perfon. It may feem at firft, difficult to re- member, what letters the notes imply, and I fhould have thought fo too, had not the making out of the alphabet only impreffed my mind, with the remembrance of every letter, and yet I cannot boaft of having [ 74 ] a good memory; but upon trying the ex- periment in my family, I find that it is attainable, by writing them down two or three times, without any further trouble: indeed to remember a name, or a word, it is beft done by writing it down, though it be only with the finger, upon a table, without any mark; as the hav- ing turned the form of the letters by the hand, will greatly affift the memory, Biſhop Wilkins thinks it poffible, that if inarticulate founds can be contrived to exprefs not only letters and words, but THINGS and NOTIONS, then there might be fuch a general language formed, as might be equally Speakable by men of all nations, and fo reftore to us what we loft, by the fecond general curfe, which is yet manifefted unto us, he fays, not only in the confufion of writing, but alfo in fpeech. But I am apprehenfive this univerfal language may fleep quietly with the flying chariot, the fame author, was once fo bufy in conftructing. 201 IN [ 75 ] Ir it be aſked why men are not able, in thefe days, to decypher the Egyptian Hieroglyphicks, as well as other characters, it may be, that we are not fufficiently ac- quainted with the rites and myfteries of their religious worship. Hieroglyphicks fignifies facred fculpture; and this they carved upon pillars and pyramids, and painted them upon cottins, mummies, &c. fo a King was expreffed by a bee, who had the fweets to feaft upon, and a fting to puniſh. A ferpent with the tail in his mouth, reprefented the revolution of the year, by returning into itfelf: fo when Darius was wearied out, in the war with the Scythians, they fent him a prefent of a bird, a mouſe, a frog, and a bundle of arrows; intimating thereby, that 'till the Perfians could fly like birds, or con- ceal themſelves under the water like frogs, or live under the earth like mice, they could not efcape the Scythian arrows. It was formerly esteemed amongst us, a matter of great ingenuity, to convey a re- markable [76] markable expreffion, or form a device, to exprefs a man's name, by this method; and there are at this day, carved orna- ments, in many of the old family feats, which were defigned to convey the name of the original family, to future ages, and do fo, as a Tun, with a bolt through it, for BOLTON; and flip, by an eye and a flip of a tree; an Earl of Arundel deco- rated his houfe with a capital A in a rundle; and Mr. Harebottle, by a Hare on a bottle! But how far fuperior was the enamoured youth in the following device? Being violently in love with Rofe Hill, he caufed to be painted on the bor- der of his cloath, a rofe, an hill, an eye, a loaf, and a well, i. e. Rofe Hill I love well. If therefore, the ancient Hieroglyphicks have no more ingenuity in them than the modern, we need not be over folicitous to underſtand them. If we go back fome hundred years for a fpecimen of our language, moft men would require the affiftance of a Decy- pherer [ 77 ] pherer to explain it, as the following fpe- cimen of the Lord's Prayer will evince. Our Father which art in heaven Uren Fader thy kingdom be thy will fo thic arth in heofnas as in ther ric fic thir villa fue is in heaven and in earth our lofe heofnas and in earths uren hlof fuper-fubftantial give us to day and fer wiftlic fel us to daeg and forgive us debts ours fo we forgive forgef vs fcylda urna fue we forgefan debts ours and do not leade us feyldgum urum and ro inlead ufith into temptation but deliver every one in cuftnung ah gefrig urich from evil. from ifle. Amen. NOR was the Lord's Prayer writ in much better English than the above, 'till Richard the Second's time. And here I cannot help reviving an English word, ſcarce known; and yet, it is one, which levied armies, and faved a kipgdom. WHEN [ 78 ] WHEN there was a dangerous rebellion againſt King William Rufus, and Ro- chefter Caſtle ftoutly maintained by the rebels, he iffued out a proclamation, that thofe of his fubjects who neglected to re- pair to his camp, fhould be reputed Nidings; and upon this they fwarmed to him from all parts of the kingdom; and their numbers difmayed the rebels fo much that they yielded; fo that this one word (Niding) though now loft, faved a kingdom. usb 200 ob bos IN CHAPTER V. N the fpecimen given in the firft plate, of fecret writing, by the harmonic alphabet, it muſt be obferved, that every note implies a letter alfo, and confequently under fuch a reftraint, it can only have the appearance, and be the picture of mufic, without the harmony; yet it is fuch a pic- ture as muft pafs unfufpected by all who do not underſtand mufic perfectly, and by many [79 ] 45 many who do; at leaſt thoſe who do, would moſt likely confider it only a wretched at- tempt to compofe mufic, without fufpect- ing that the notes conveyed two lines of true poetic harmony, from that ſweet poem of Dr. Goldfmith's, THE DESERTED VILLAGE; and therefore this method is, in one refpect, to be preferred to every other yet practifed, of fecret writing, i. e. that it is leaft liable to fufpicion. An itinerant fiddler, or mufician, with his dogs-ear'd mufic book in his pocket, might get admittance into, or from a town be- fieged, unfufpected. A tune might be pricked down in his book, among many others, and he might be defired to give 173 a copy of it to any particular perfon where he is going, without fufpecting the mifchief, or good office, he is employed to execute, and confequently unable to betray the fecret; and though fufpicion fhould arife, how will the Decypherer know which, among a great number of mufical airs, conceal the fecret informa- tion? In this cafe a good Decypherer fhould [ 80 ] fhould be a good muſician alfo, that he may pick out the moft uncouth and con- ftrained compofition: for that would, moft likely, prove to be the harmonic epiftle. Therefore to obviate this, and to render the matter lefs liable to fufpi- cion, and much more difficult to be de- cyphered, in the fecond plate, an air, compofed of trebble and bafs, according to the rules of true compofition, is given. In this plate, there are a great number of null notes to fill up, and to compleat the harmony. The confederate, who is in poffeffion of the key and alphabet, will know the null notes by their tails being all turned upwards, and therefore he paffes over them, and takes down in or- der, from the bafs and trebble cliff, thofe only which are turned downwards; a cir- cumftance which would greatly perplex, the Decypherer; firft, to find out whether all the notes were active; fecondly, whe- ther the bafs and trebble cliff were both employed; and lastly, which were the null notes: yet this method is not without fome [ 81 ] fome inconveniences, and fuch as would create fufpicion or furpriſe in an examiner who underſtands mufic. For being con- fined to turn all the nulls one way, and. the active notes the other, it muſt fome- times happen, that both muſt be occafi- onally conſtrained, and the tails frequent- ly turned contrary to the ufual practice in writing of mufic. Ir is poffible to render this method of writing ſtill more fecret, by placing a very thin bafs under the treble, and to put refts, &c. under fome of the active notes, and to point out the others, by a mixture or liquor (of which there are many) that would not appear 'till the paper is held to the fire, dipped in water, or fine duft thrown over it; and under all thefe impe- diments, it would be very difficult to come at the fecret matter, yet it is what a good Decypherer would not, I believe, give up, as a thing not to be done. WERE I, however, under a neceffity to fend a letter of the utmoſt importance, which was to pafs through the hands, or F under [ 82 ] under the infpection, of cautious exami- ners, I fhould think a good piece of harmonic compofition, without any words annexed to it, the fafeft and moft fecret vehicle to convey it under. In letters, where it is neceffary to be parti- cular, as to the day, month, or even the hour, that may be done by a kind of fhort hand; for it would be very unfafe to write, though in Cypher, Dear Sir, at the top of a letter; or your humble fervant, at the bottom; or even the month, the year, or the day of the month, as thoſe words would be firft exa- mined by a Decypherer. To avoid any of theſe clues, therefore, where the month and the day is to be given, it may be con- veyed, according to the Quakers' bye way. Let the twelve firft mufic lines be confi- dered to ftand for the twelve months of the year, and then, counting from the first, to the thirty-first, the days of the month. If therefore I would date my letter the 8th day of April, a fmall dot on the fourth line preceding the first note, as in plate the [ 83 ] the fecond, would imply the fourth month, and a little daſh acrofs the eighth line, in the fame manner, would fhew it to be dated the eighth day of the fourth month; and a little x from the first to the twelfth line, would imply any particular hour of the day; or an o the hour of the night. It is very certain, that if fuch a fentence as the fpecimen in the fecond plate con- tains, can be conveyed by a few lines of mufic, a long letter may eafily be framed, within the compafs of an Italian air in fcore; nay, that any Italian piece of mufic of a tolerable length, may, by writing it with the tails properly turned up or down, according to the fpecimen here given, be made the vehicle of a letter, or a piece of important information; and ftill more eafily might a good compofer convey the words, and the harmony alfo, by the fame characters. Confcious how- ever of my own inability to execute a matter of fo much ingenuity with any degree of fuccefs, I applied to Dr. Axe, and made him acquainted with my faint idea F2 [ 84 ] idea of the bufinefs, and aſked his affif- tance. But though the Doctor is un- doubtedly an excellent compofer of mufic, I more than fufpect by his total filence! that he has not the moft diftant idea, of what I thought I had laid before him in very plain notes. I am fure it was in very civil terms. THE Doctor's filence, however, brings to my mind a queftion, a fellow traveller of mine, many years ago, put to a fhep- herd we met on Saliſbury Plain. How often (faid my fellow-traveller to the fhepherd) honeft friend, do you vivify a year? The fhepherd looked earneſtly at him---fimpered---fcratched his head--- and then, firoaking his long chin, without afking the meaning of the word, replied, We do call it Sheep-fheering: for he was the beſt ſheep-fheerer (as we afterwards heard) of all the paftoral fwains upon that plain. If it be aſked, why I applied to the father and not to the fon, I answer, becauſe he might have expected me, in return, to employ him to teach my daughter [85] daughter mufic, and I do not like his manner. Though this bufinefs did not vivify the ingenious Doctor, I am con- vinced that a good compofer of mufic, either by framing the harmony by the alphabet, or the alphabet by the harmony, may not only render every note active, but by harmonic alphabets, might write two letters on different fubjects, one in the trebble cliff, and the other in the bafs; and it is evident, therefore, by the fpeci- men I have given, that the words of a fong may be conveyed by the harmony; for any judicious finger, by dividing pro- perly the words and repeating them, as is ufual in finging fongs, may fing thofe in due time, with the air which conveys them; and though I confefs I fee much harm might arife from it, yet it may be right to obferve, by the bye, that an harmonic letter thus written, could not eafily be brought home with any degree of cer- tainty (efpecially where null notes are employed) fo as to convict the wri- ter in a court of juftice; yet I cannot think F 3 [ 86 ] think myfelf guilty of an injury to fo- ciety, in pointing this method out, as it may be productive of much good, as well as of mifchief; for fecret writing is abfolutely neceffary on many important occafions of ftate. I will here give one ftriking inftance of its utility. I will fuppofe, and I ought to fuppofe it, that the Queen of Denmark is a virtuous Princefs; that a faction has been formed in Denmark, to dethrone her husband, and perhaps to deprive her of life, as well as of liberty; that no letter can pof- fibly be conveyed to her, which has not been previouſly feen, and the contents carefully examined. I will fuppofe the King her huſband, or the King her bro- ther, defirous to affure her of their ut- moft protection, yet quite unable to con- vey fuch comfortable information to her. Now fuppofe the Queen to have been in poffeffion of an harmonic alphabet, how eafily, and with what propriety, could the King her brother, write her an affectionate letter, in common terms, and fend her a little [ 87 ] mufic to divert her thoughts and employ her melancholy hours? I dare fay in fuch a cafe neither the Colonel of the Guard, nor the Governor of the Caftle of Cronenbourg, would have fuf- pected that a few fheets, or a book of mu- fic, without any vifible words, conveyed that unfortunate Princefs fuch informa- tion as her Royal Brother wifhes perhaps, at this minute, to fend to her. For this fweet mufic, might call upon her, to fup- port her fpirits, and affure her, that a fleet ſhould foon appear, and deliver her from her confinement. But fuppofe, that the mufic was even fufpected to con- tain private information, and therefore not delivered, I believe I may venture to fay, a fleet might fail from England to the Baltic Sea, before a Danish Decy- pherer had picked the intelligence out of an old fong, without words; and then the moſt that could be made of it, would be, that fome private information MIGHT be concealed in the mufic. But an inter- cepted letter written in evident Cypher, even while it remains undecyphered, carries certainty [ 88 ] certainty with it, and puts every body concerned, as I faid above, upon their guard. It therefore might be right for foreign Embaffadors, or Princeffes, who are feparated from their families, by fo- reign alliances, to be in poffeffion of fome kind of mufical alphabet, by which they may write, or receive letters, which are not fufpected to be fo. The prefent mode, I believe, is, to do all this bufi- nefs, by what is obviously writing in Cypher; and that too, by fome method which has long been in ufe, the key to which, I have more than reafon to be- lieve, moſt of the Princes in Europe are in poffeffion of. I will hardly believe that the K- of, for inftance, is a ftranger to every mode of Cryptogra- phical writing by the feveral Princes and States in Europe. How often do we hear of a courier being murdered, and his diſpatches carried off? and for what other purpoſe, but information? and without the key, to decypher letters fo written, to what purpofe fhould they be inter- [ 89 ] intercepted by fuch a deed? I have confidered every method of fecret writ- ing, which I have heard of, either of ancient, or modern practice, and I fub- mit it to the reader's confideration, whe- ther writing by an harmonic alphabet is not, of all others, the moſt void of fuf- picion; perhaps I fhould fay, was not; becauſe having publiſhed it, the fecret is divulged; but as Bishop Wilkins's fwift mef- fenger; and Falconer's art of fecret infor- mation, are both very ingenious books on this fubject, and have both been publiſhed many years, and yet are but little known, except by the very few, who have ftudied the art of writing in Cypher, I cannot fuppofe this performance of mine, in every refpect fo inferior, will ever be much known, and therefore it may prove ufeful to a few individuals of my own country, and never do mifchief by finding its way into any other. And here it may be proper to acknowledge, that I have borrowed many of the fub- jects [ 90 ] jects I have treated of, from the two in- genious works above-mentioned, becauſe they are very ſcarce books, being chiefly in private hands, and confequently are, what the bookfellers call, out of print. I have obferved elſewhere, that Bishop Wilkins juft hints at the method of writ- ing by mufical notes, and he is the only writer, I believe, who ever mentioned this method; though I think I have fomewhere read, that there was a people (but I doubt they were inhabitants of the moon) who converfed entirely by mufical inftruments; and I have feveral times wifhed, that were the cafe with us, when I have heard a parcel of men all talking together :- Harmony might then make one fome amends. DURING the writing of thefe fheets, an abfent friend, who knew what I was about, fent me a letter written in cypher, but not confidering the matter fully per- haps, thought that I ſhould be startled at a letter, compofed from the Ethiopic and Etrufcan alphabets, and by way of rendering [ 91 ] rendering it ftill more difficult, every word is French, but which, according to auri- cular orthography, when read as Engliſh, feems to be fo. This Anglo-Franco letter, which is fet forth in the third plate, my ingenious correfpondent, was well fatisfied, could not be read, and continued in that belief 'till the return of the poft, when the received an anfwer, written in her own alphabet; and though the decy- phering of it, was done in lefs time than it was writ, and I am far from claiming any merit in reading it (as nothing of the kind can be more eafy) yet the method being fingular, I have thought it might entertain fome readers, by inferting the letter, as well as the Cypher in which it was written. It is a ftrange mistake, that thofe who at first confider the matter of writing in Cypher, fancy it difficult, in proportion to the uncouthnefs of the characters, in which the letter is wrote; whereas the change of one letter, fuch as the Roman Generals made, is equally as obfcure, and in fome refpects, to a young 20 beginner, [ 92 ] beginner, more fo, than any other: but I must obferve, that my female corref- pondent avoided giving me that light, which perhaps an alphabet of her own compofition, would have yielded, for the reafons I have before mentioned, and therefore did well, in taking her cha- racters from the Ethiopic and Etrufcan alphabets, which fhe found ready formed to her hand. I do not find one word in the follow- ing letter but what is to be found where I conclude they were taken from, i. e. from a French Dictionary. I began at firſt to exult at the (If) and the (For) but I found upon examination, that the former is the name of the yew tree, and the lat- ter, the name of an Ecclefiaftical Court in France.

THERE are feveral miſtakes in the third plate which the engraver (who is no de Before cypherer) has made, and which the reader, rece Preface who will be at the trouble of examining it, is defired to excufe and to correct. The laft letter of the firft word on the third line is wrong, the character repre- fents a k, and it fhould be a c; in the fifth line three characters are omitted, inſtead of the word lute, the I only is in- ferted; the laft word of the fifth line (canne) has two mm's, inftead of two nn's; the fixth word in the twelfth line begins with a k, instead of an h; and the 110 firft [ 94 ] first character of the fifth word in the laft line fhould be s, inftead of an e. But fuch mistakes as thefe are very common, and fuch as a Decypherer will eafily de- tect and correct, as he proceeds, in exa- mining the Cypher; for when a few words are difcovered, fuch as that, the, them, there, thofe, and, are, &c. &c. the myſtery unfolds very faft, for if the characters to fuch words anfwer in gene- ral, there can be no doubt of being in poffeffion of the compleat alphabet, in a fhort time; though the writer may have made a few literal errors, and therefore thoſe who at first fight feem alarmed at the difficulty of making out my female friend's letter, are defired to confider it attentively for half an hour, and they will not then throw it down, and pro- nounce it an impoffible, or even a diffi- cult, taſk to accomplish, between their breakfaſt and dinner. CHAP. [ 95 ] I CHAPTER VI. Shall here add to the foregoing trea- tife, fome of the many devices, ftra- tagems, &c, by which fecret information has been conveyed from one party to another, or from friend to friend. MACHIAVEL, in the feventh book of the Art of War, fays, "Some have writ- "ten what they had to fay, in the fcabbard "of a fword; others, have put their let- "ters into paſte, which they have baked, "and given to the bearer for food upon "the road, or concealed it under the "collar of the meffenger's dog; others, "have fent letters about common buſineſs, " and interlined them by writing with a compofition, which will not appear 'till "they have been dipped in water, or held "to the fire:" And gives an inſtance, in his own time, of one, who having oc- cafion to communicate a fecret to fome of his friends, who lived in a town which 66 was [96] was befieged, and not daring to truft the meffenger with it, fent letters of excom- munication, written in the ufual ftyle, but interlined, in the manner above, which being fixed to the doors of the churches, were foon taken down, and the contents of them perfectly under- ſtood, by thoſe who knew from whom they came, by fome particular marks. A letter of common bufinefs may be interlined, by writing with Sal Ammoniac diffolved in water; or with the juice of a lemon, thefe letters will not be vifible 'till they are held by the fire, but a letter fo written, will in a fhort time difcover itſelf, from the corroding acid, and moisture of the liquid. So a letter written with diffolved allum, will not be difcernable, 'till the paper be dipt in water. LETTERS written with urine, goat's fat, or hog's lard, will not appear 'till duft is thrown upon them; and it was by this ftratagem, that Attalus obtained a victory over the Gauls; for having ap- pointed a day for facrifice, he writ back- wards [ 97 ] wards upon his hand, with goat's fat, Regis victoria; fo pulling out the en- trails of the facrificed beafts, he preffed them to his hand, and as the prieft turned them up and down in the duft, the words foon appeared legible, and this pious fraud encouraged his foldiers fo much, that it gave him the victory. A letter may be writ with the yolk of a white an egg, and when the letters are quite dry, the paper muſt be blacked all over with ink, and the confederate, by fcraping the paper gently with a knife, will expofe the letters written with the egg, while the reft of the paper continues black. SCHOTTUS directs a letter to be writ with two inks, the fecret one with com- mon ink, made very faint, by mixing it with water, fo that the writing will be fcarce vifible, and when it is dry, write an ordinary epiftle over it, with ink made of gun-powder, beat, and mixed with rain- water, upon the firft letters; and thofe, he fays, will wash off, with a fponge dipt in galls, which will alfo blacken the firft. SCHOTTUS G 9 [ 98 ] SCHOTTUS alfo mentions an ingenious method of concealing a letter in a glafs bottle, by taking the bladder of a hog, or a calf, and having blowed it full up, and being thoroughly dried, it is writ upon,then preffing out the air, put it into a bottle, leaving the neck of the bladder above the neck of the bottle, then fill it with oil and cork it up; and thus it will be fo clofely extended to all parts of the infide of the bottle, that neither the writing nor the bladder will be vifible. Ir is poffible to open an egg at one end, and extract the contents; and put a letter within it, and fill up the hole neatly with another bit of egg fhell. FALCONER feems to think the Lacede- monian Scytale contrived by Archimedes, who lived about the year of the world 3755, to have been the moſt early, and the moſt univerſally practifed; if it were fo, it is evident, from the fpeedy manner of reading a letter fo written, and which I have before pointed out, it is far from having any great ingenuity in the contri- vance. IT [ 99 ] Ir is probable, the Scytale gave rife to a practice in the Greek Church, where the Priefts at Divine Service held in their hands, A KONTAKION. This Con- tacium was a fhort staff, to which was made faft, and wrapped round, very long flips of parchment, confifting of a great number of pieces, on which were written, the prayers and offices to be per- formed by the Priefts. A very curious one is now to be feen in the French King's library, adorned with accents and letters, or rather half letters, for it is a perfect Scytale. To improve the Lacedemonian Scytale, dip a long thread in allum water, then roll it about a rod, or ftaff, in a ferpentine revolution, and write upon it; but this alfo may be foon read, for the distance between the firſt and ſecond mark of the ink, gives the circumference of the Scy- tale; and it is the fame thing at which end of the thread you begin; for if you take the laft letter inftead of the first, turn the rod, and put that end down- wards G 2 [ 100 ] wards which was uppermoft, and it will appear in order Baptifta Porta mentions the writing on the edges of books and on cards, as a method practifed for fecret purpoſes, by pulling back the leaves of a new bound book 'till the edges of the paper fall awry; and thele leaves, when written upon, and returned to their pro- per pofition, appear only to have fuch fpecks of black, or red ink, as are often thrown upon books for ornament: to dif- cover this, is only to fufpect it; the cards indeed require more time, becauſe the confederates may have agreed to the order in which they are to be placed; yet, by taking any one card, and looking out another which exactly tallies to it, you will foon find thofe which are to go before and follow, 'till they are all in their pro- per order. AN epiftle has been formed round a half dipt wax candle, and then covered over by freſh wax, and a verbal meffage fent, that it would light him to his business. In Baker's Chronicle, there is an account abrew of [101] of one Froft, who carried letters concealed in his walking ftaff, between the rebels in England and Scotland. Some have conveyed private intelligence written up- on leaves of trees, and thefe leaves put on to cover ulcers on the meffenger's legs, and even fome have been engraven on the meffenger's flesh, a practice as old as Ovid. "Caverit hoc cuftos, pro chartâ confcia tergum Præbeat, inque fuo corpore verba ferat. And long before Ovid's time, Hiftiatus, the tyrant of Miletus, fhaved the head of one of his fervants, as an effectual method of curing his fore eyes, and writ his fecret intention upon his head; then letting his hair grow, fent him to the Perfian General, under pretence of perfecting his recovery, directed him, when he came to Ariftagoras, in Greece, to tell him, that it was his re- queft the General would fhave his head with his own hands, as he had done; and thereby the meffenger's head delivered a fecret which never troubled his brain. THERE [ 102 ] THERE are an infinite number of theſe kind of devices mentioned by Baptifta Porta, Schottus, Bishop Wilkins, Falconer, and many others; but they, like thoſe I have given above, are trifling, and only to be read for amufement rather than prac- tice, and therefore I forbear reciting more of them. THE method by which the private in- formation was given, in the letter of ex- communication, was probably this. THE Confidants at parting frame an alphabet of figures to write by thus: Abcdefghik 1 m 11 13 18 3 19 12 8 S t u W x y 4 22 10 9 I n o p q r 20 2 21 23 7 6 5 Z 15 14 16 17 24 Now having writ down the fecret matter on a paper, they contrive a letter of common bufinefs in any language, they look out the numbers of the alphabet that exprefs the letters of the fecret writing, and counting the letters in the common miffive from the beginning, they add fome private mark under every cha- [ 103 ] character, of the refpective numbers.

The epiftle thus: HAVING underſtood that I could not be fafe any longer where you are, I have chofen rather a voluntary banishment, to wander with my liberty abroad, than to lie under the daily hazard of lofing it at home. 'Tis in my opinion the leaft of the two evils: 'tis true, I am innocent, but innocence is not always a buckler, fo that I hope you will not condemn, even though you cannot approve, my choice; at leaft 'till you have the particu- lars of my cafe, which expect per next. OBSERVE, the figure for the firft letter, to be put in Cypher, is 3; therefore a fecret point or dot must be placed im- mediately under or over it, i. e. under u; and [ 104 ] and number 6 expreffing the fecond let- ter, a dot muſt alio be placed under n; n, being the fixth letter from v; and eighteen letters from n, will ſtand another dot, and fo on; in this manner. HAVING understood that I could not be fafe any longer where you are, I have chofen rather a voluntary baniſhment, to *** wander with my liberty abroad, than to lie under the daily hazard of lofing it at * home: 'tis in my opinion the leaft of the two evils. 'Tis true I am innocent, but innocence is not always a buckler; fo that I hope you will not condemn, even tho' you cannot approve, my choice, at leaſt 'till you have the particulars of my cafe, * which expect per next. THE points may be fo made as not to be vifible 'till held to the fire, or dipt in water. 7210 To [ 105 ] To decypher this, you must take down the number of letters from the beginning of the epiftle to the firft point, from that to the fecond, and fo on, from point to point, to the laft; and then it becomes the fame as a plain cypher, and is decy- pherable in the fame manner, as men- tioned in the preceding chapters, for by making a different character, to reprefent every different diftance you find between the dots, you will have the fame variety of characters (and it is no matter what) as there are variety of letters ufed in the fe- cret information: for inftance, fuppofe you reprefent the 5th dot by a †, you will find, by counting the number of letters or nulls between that, and the next dot, to be twelve; and as there is juft the fame number, between the fourth dot and the fifth, as there is between the fifth and the fixth, you will find that alfo must be a †, and though this does not directly inform you what letter the † is to exprefs, yet you are certain it is fome word, where two and the fame letters are conjoined, and [ 106 ] and this is a great help towards coming at the reft; and here I fhall finiſh this en- quiry, having faid enough, and more than is neceffary, to lead thofe who have leifure and inclination to purfue this ſtudy, into the road at leaft, which will convey them to their journey's end; and only obferve, that though my own method of fecret writing, by the Harmonic Alphabet, may have lefs ingenuity than any of the others, which are recited above, yet it certainly has, or at leaft had, before the publication, one advantage of moft of them; namely, that of being the leaft liable to fufpicion. BUT before I conclude, I cannot help mentioning a laughable experiment infift- ed upon by fome, of bottling, as it were, up words in a tube, or trunk, one end of which being quite clofed up, fo that no air can enter, the words are to be con- veyed by the mouth into the other, and then inftantly corked and fecured from taking harm by the air; and thus the tube may be conveyed an hundred miles, or more, [ 107 ] more, to the hands of the confederate, who, upon uncorking the contrary end of the tube, that the words were put in at, lets them out in due order. But this is to be done only, in that country, where the intenfe cold freezes up the words of the fpeaker, which are never heard by any, 'till the following thaw hatches them into found. BUT though articulate founds cannot be thus arreſted, yet there are feveral ways of directing and conveying founds to a very confiderable diftance. The Emperor Severus, fortified the North of England, by a wall extending from Car- lifle to the Tine, at every mile diftance there were towers, and between the towers watch-houſes, at a convenient diſtance, from which pipes of brafs were concealed in the curtain of the wall, fo that in a very fhort time, the troops ftationed in the feveral towers, had notice when the enemy approached. Albertus Magnus fpent thirty years in framing a fpeaking ftatue, which Aquinas wilfully [ 108 ] wilfully broke, and rendered fpeechless. But this could contribute nothing to fe- cret information, and was only to be ad- mired for the mechanifm of its parts. It is needlefs almoft to mention Tachy- graphy, or fhort-hand writing, as it hardly comes under the denomination of fecret writing, for where notes are uſed to ex- prefs fyllables, and fometimes words, he who underſtands one kind, of fhort hand, may read any, for you may judge of fylla- bles, when expreffed by fingle characters, by their frequency, &c. as of letters, and befide this, you have the advantage of dif- tinguishing the vowels, which are not ex- preffed, but understood, by the places of the notes, (that together with their own proper powers) exprefs thofe of the fe- veral vowels. Among the Romans A was the mark for abfolution; c of condem- nation; N. L. Non Liquet; and N. D. Neci datum. And their Judges writ their feveral opinions upon a Teffera, in capital cafes; hence it was that A was called Salutis [ 109 ] Salutis Litera, and C Litera Triftis. But their Notaries encreaſed the number of abbreviations to fuch a degree, for the fake of difpatch, that at length it occa- fioned fo much confufion, that Juftinian difcarded the ufe of them, though we have retained that cuftom from them down to this day in the A. D. for the year of Chrift; and indeed the knowledge of- the ancient abbreviation, is very ne- ceffary, in order to underſtand the reli- gious worſhip, as well as the civil laws, of the ancient Romans, as they generally confecrated places, or things, by the firſt letter of the words, then well under- ftood, fuch as Mer. S. for Mercurio Sa- crum; M. I. Maximo Jovi; D. Im. S. Diis Immortalibus Sacrum; D. P. Dies Penatiorum; D. O. Diis Omnibus; I. O. M. D. Jovi Optimo Maximo Dedicatum, &c. SINCE the above fheets have been printed off, I have had an opportunity to be convinced, that a perfon born deaf may, at a proper age, being otherwife of good [ 110 ] good parts, not only be taught to read, to write, to make known his wants, and to communicate his ideas, but that it may be done, in almoft as fhort a time, as a child can be taught, who does not want the ſenſe of hearing: indeed it was the obfervations I had made on the quick parts, and ready perceptions, of a faith- ful fervant, now living in Lord Bate- man's family, who was born under this defect (for he is too happy to call it a misfortune) which firft led me to confider that matter, and that led me into the other fubjects I have here treated upon; but I am told there is a very ingenious book, which however I cannot procure, written by a Dr. Watts, upon this laft fubject, wherein he gives the neceffary inftructions to teach the deaf to read and to write. The CONCLUSION. Decypherer, before he fets about his bufinefs, fhould endeavour to know from what part of the world the A in- [ 111 ] intercepted letter in Cypher came, and from that circumftance, confider what language the cypher is moft likely to be wrote in, as that may fave him much pains, time, and ftudy. He must confider alfo that the Oriental Languages, as He- brew, Chaldaic, Syriac, Samaritan, Coptic, Perfian, Arabic, &c. are writ from the right to the left, and that only the Armenian and Ethiopic are from the left to the right. ON the contrary, all the occidental languages, as Latin, Greek, Spanish, French, German, Italian, Sclavonic, and English, are writ from the left hand to the right. At first the Greeks writ from the left to the right, and back a- again, from the right to the left, as land is ploughed. Hence literas exarare, fignifies to write, a metaphor taken from the manner of ploughing the ground. Nevertheleſs it muſt be confeffed that two ingenious men, who are to be feparated from each other, may previously agree, upon fome method, whereby they may cor- LIKE YOU AND ME [ 112 ] correfpond by letter, in a manner that is fcarce poffible to he difclofed without the key; and I fhall inftance one: Suppofe the parties agree to correfpond by New- ton's first edition of Milton, or any other books, and thereby direct each other in their letters, to fuch a page, fuch a line, and to fuch a word; who, I fay, would be able to find out by their writing page 7, line 2d, words three, four, and five; 2 vol. page 8, line 19, word 4; fame page line 9; words words 3, 4, and 5; was to fay that THE WESTERN EMPIRE IS DE- GENERATED INTO LICENTIOUSNESS? with- out being told, that thefe words will be found, in the firft and fecond volume of Farneworth's tranflation of Machiavel's Works, the first three words, from his hiftory of Florence, and the remainder, from his political difcourfes of the firſt Decad of Livy, FINI S.
