'^ i ^ HE essence of our Tercefitenary Celebration lies -/ neither in pageant^ feast, nor holiday, neither in the distribution of academic honours, nor iji theinte?'- national congress of illustrious men, natural and fitting accompaniments though all these are ; but wholly in the commemoration of the Past, in the reverent re7nembrance of the lives and labours of those bygone generations, to whom, seldom though we acknowledge it, we owe, alike for our institutions and our culture, a debt so infinitely vaster than to our own. And such co7?imemoration is all the i?iore needful in these times of sternest criticism and impending chafige, when no 7nere general claims of wealth, or dignity, or age, exempt fro7n trial and question. It is well, therefore, at this time to su7n up such evidence as we may of past efficiency, to show for our University " 7vhat gain fro7n all her toil appear s,^^ and out of the records of th7'ee centuries to 7)iake up at once ojir Roll of Honour and our Cloud of Witnesses. PREFACE. Hence this little book., which though all too hastily prepared in lack of any more formal catalogue^ yet honestly aims »at giving a terse account of each of the University's most illustrious sons^ and of their con- tribution to the world^s progress. In few departments have these contributions been small., in some unnumbered and inestimable. For the progress of literature and history from Row and Drummond to Scott a?id Carlyle, of philosophy from Ferguson to Hu7ne^ or of sciefice from Maclaurin to Maxzvell, Hutton to Murchison., Darwin to Darwin., cover's not merely the intellectual evolution of our university or even country., but well-nigh spans that of mankind. Hence the names are arranged in approximately historical order., without reference to the archaic Faculties., much less to personal rank or success., whether academic or social., but accordifig to the great movements which they mainly influenced ; and these again are thrown into three series — Science and Philosophy., Art, and Public Life — an arrangeffient which though perhaps not strictly philosophical, was found to present fewest difficulties in practice. The list includes none whose relation to the University has been merely honorary, but any {eve?i though their connection with other seats of learning may have been more pe7'manent), 7vlw have PREFACE. for a season either drunk of her springs or dispensed its waters. But the world-saturating influence of a great University is not wholly^ perhaps not even mainly measured by that of her great me7t, but rather by those unnamed thousands of her humble scholars whom she has sent forth throicghout all times and lands to teach and govern^ to work and heal. Hefice 7ve, who seek only to follow in their steps., would commemorate not only the few greatest ivhom she has in varying measure schooled for the service of Hujnanity., but the unnum- bered niultitude of faithful men, whose voices have swelled the Choir Invisible. Our Festival then, is not only an All Saints\ but an All Souls Day ; the Past is lighted up not merely by a thin line of flari7ig torches, but by the calmer radiance of a mist of stars ; it rever- berates not only with the ^nighty ti'ead and pealing voices of the Heroes, but with the Chorus mightier march and song. SCIENCE AND PHILOSOPHY MATHEMATICIANS AND ASTRONOMERS. James Gregory. — Aberdeenshire, 1638 — Edin. 1675. Student in Aberdeen and Padua. Professor of Mathematics in St. Andrews (1668), and in Edinburgh (1674). To him we owe one form of the reflecting telescope. He investigated the transformation of curves and the measurement of their solids of revohition, and vvrote on optics and on purely mathematical subjects, e.g. Vera Circuli et Hyperbohc Qiiad- raHira. David Gregory. — Aberdeen, 1661 — ^Maidenhead, 1710. Student and Professor of Mathematics in Edinburgh, and Savilian Professor of Astronomy in Oxford. His greatest work Astronomicc Physiccc et Geoinetricx Elementa was esteemed by Newton himself as a most excellent illustration and defence cf his system. He taught the Newtonian doctrines in Edinburgh before they were taught in Cambridge or else- where, and published a complete edition of the works ascribed to Euclid. Colin Maclaurin. — Kilmodan, 1698 — Edin. 1746. Student in Glasgow, Professor of IMathematics in Aberdeen and in Edinburgh (1725). He wrote A Treatise of Fluxions, in which he answered Berkeley's attack by founding the method on geometrical demonstration. He also applied the method to various physical problems, such as that of the motion of the tides. His theory of the attraction of an ellipsoid of revolution, Lagrange describes as " un chef d'oeuvre de geometrie qu'on peut comparer a tout ce qu 'Archimede nous a laisse de plus beau et de plus ingenieux." A MATHEMATICIANS AND ASTRONOMERS. He deserves also to be remembered as the friend of Newton, whose Principia he expounded in a vahiable treatise, and the author of Geometria Organica. He was charged with the defences of Edinburgh Castle against the Pretender in I745. Matthew Stewart. — Rothesay, 1717 — Edin. 1785. Student in Glasgow, and Professor of Mathematics in Edinburgh <^747)- . . , ^ Essentially a geometer, he published in 1746 a book of General Theorems, all except the first five without proofs ; and in 1763 a Collection of Geometrical Propositions," demonstrated in the manner of the ancients." William Wallace.— Dysart, 1768— Edin. 1843. Student, and Professor of Mathematics in Edinburgh ( 1 8 1 9- 1 838) . He wrote numerous mathematical and astronomical papers, £.g.y on Geometrical Porisms, on the Computation of Logarithms, on the Analogous Properties of Elliptic and Hyperbolic Sectors, two Elementary Solutions of Kepler's Problem by the Angular Calculus, etc. Thomas Henderson. — Dundee, 1798 — Edin., 1S42. Astronomer Royal and Professor of Astronomy. He determined the parallax of a Ccntauri. Philip Kelland. — Dunster, 1809 — Bridge of Allan, 1879. Studied at Cambridge, and Professor of Mathematics in Edin- burgh (1838-1879). His most important researches were in the department of pure mathematics, c.g.^ his clear and elegant papers on General Differentiation, on the Theoiy of Parallels. He also investi- gated such problems as those of the aggregate effect of interfer- ence and of wave motion. A distinguished teacher. John Playfair, Professor of Mathematics, 1785 ; Sir John Leslie, Professor of Mathematics, 1805 ; and Thomas Carlyle, Translator of Legendre's Geometry, and author of an essay on Proportion, are commemorated under other heads. PHYSICISTS AND CHEMISTS. Joseph Black. — France, 1728 — Edin. 1799. Studied at Glasgow and Edinburgh. Successor to Cullen in the Chair of Chemistry at Glasgow (1756) and Edinburgh (1766). His name is ever associated with two great discoveries — one in Chemistry, the other in Physics. The former is his discovery of Carbonic Acid gas, whose relation to the caustic alkalies he clearly demonstrated. By this discovery, he refuted the supposi- tion that limestone on being burned became caustic in virtue of something which it obtained from the fire ; and showed that its altered property was due to the escape of carbonic acid, so giving the death-blow to the Phlogiston theory, and demonstrating the value of quantitative analysis. Not less important and valuable to science was the beautiful series of investigations which resulted in his exposition of Latent Heat, and placed the subject much in the position it holds at the present day. John Robison. — 1739 — 1805. Student in Glasgow (1766); Professor of Chemistry in Glas- gow, and of Natural Philosophy in Edinburgh (1774). He made many contributions to the science of mechanics ; was an intimate friend of James Watt, and it was probably at his suggestion that Watt directed his attention to the improvement of the ste^m engine. Daniel Rutherford. — Edin. 1749 — 1819. M.D., 1772. Professor of Botany. His doctorial thesis contains his discovery of nitrogen. Thomas Charles Hope. — 1766 — 1844. Professor of Chemistry, Glasgow and Edinburgh. Discovered the metal strontium. PHYSICISTS AND CHEMISTS. Sir John Leslie. — Largo, 1766— Largo, 1832. Student, vSt. Andrews and Edinburgh, Professor of Mathe- matics (1805), and of Natural Philosophy (1819), Edinburgh. He deserves to be remembered for his investigation of the Principles of Radiant Heat. His results were published in his ^'' Experimental hujtdry into the Nature of Heat.'''' He showed that light heats the bodies which absorb it, and constructed a photometer on this principle. Inventor of the differential ther- mometer, a hygrometer, etc., and author of the famous experi- ment of freezing water by the cold resulting from its own evapora- tion. He wrote also several mathematical works. Thomas Young. — Somersetshire, 1773 — London, 1829. Studied in Cambridge, Edinburgh, and Gottingen. Shares with Fresnel the honour of establishing the undulatory theory of light, and propounded the theory of interference. A learned Egyptologist, he was the first to discover the phonetic nature of hieroglyphics, and to decipher inscriptions. James David Forbes. — Edinburgh, 1S09 — Clifton, 186S. Student, and Professor of Natural Philosophy in Edinburgh (1833), and Principal of St. Andrews (i860). A voluminous contributor to the literature of Natural Philo- sophy, he made important researches as to the polarisation, absorption, reflection, etc., of radiant heat and light, and proved the identity of thermal and luminous vibrations. He investigated the conductivity of metals, rocks, etc., and showed that the conduc- tivity of a body for heat diminishes as its temperature increases. He first explained the motion of a glacier as that of a viscous body, and made many other important contributions to Geology. Sir David Brewster.— Jedburgh, 1781 — Melrose, 1868. Studied in Edinburgh. Principal of St. Andrews (1S38), and of Edinburgh (1859). Devoting himself from the first to the study of physical optics he obtained results of fundamental importance. His memory is immortalised by his many beautiful experimental researches in which he investigated the laws of polarisation, metallic reflection, and absorption of light, etc. Pie showed that the majority of non-isotropic substances are doubly refractive and in general PHYSICISTS AND CHEMISTS. biaxial, and that double refraction can ])e induced by strain and by unequal heating. Besides inventing the kaleidoscope, stereo- scope, etc., and making numerous improvements in optical apparatus, he introduced the dioptric system of lighthouse illumination. No less brilliant were his powers as an expositor of science, and besides a vast number of memoirs, he wrote many well-known popular works. Thomas Graham. — Glasgow, 1804 — 1869. Studied in Glasgow and in Edinburgh. Professor of Chemistry in Glasgow and London (1S37), and Master of the Mint (1855). His numerous and beautiful researches centre round the problem of molecular motion. He investigated the laws of the diffusion, transpiration, and absorption of gases, and established the famous law that the diffusion rate of gases is inversely as the square root of their densities. His other contributions include researches on the transpiration and diffusion of liquids, on the constitution of salts as illustrated by the case of those of phos- phoric acid, and on other more technical subjects, and were all characterised by experimental originality and simplicity. James Clerk Maxwell.— 1831—1S79. Edinburgh (1847-50) and Cambridge (1850-54). Professor of Natural Philosophy, Aberdeen (1856-60) ; King's College, London (i860) ; Cambridge (1871). His importance lies (i) in his mathematical treatment of physical problems, see 1?.^^. his Memoirs on Faraday's Lines of Force, on the Stability of Saturn's Rings, on the Kinetic Theory of Gases, and greater works on Heat, Electricity and Magnetism : (2) in his experimental power. His work on Electricity and Magnetism^ 1873, i^ said to be "one of the most splendid monu- ments ever raised by the genius of a single individual." Pie provided a physical theory- of electro-magnetism, overthrowing the conception of action at a distance, and reducing all electric and magnetic phenomena to the stresses and motions of a material medium. He also made contributions to pure mathe- matics, e.g.., on the transformation of surfaces by bending. Andrew Ure, George Wilson, Samuel Brown, W. J. M. Rankine, and John Scott Russell are commemorated elsewhere. GEOGRAPHICAL EXPLORERS. James Bruce. — Perthshire, 1730 — 1794. African Traveller. Educated at Harrow and studied civil law, etc., in University (1747). Travelled in Portugal, Spain, etc. (1757, etc.); became Consul-General at Algiers ; set out for the sources of the Nile in 1768, and returned to England in 1774. Though Bruce cannot be called the discoverer of the Head of the Nile, he at least traced to its source the Blue Nile — the main factor in the inundations which give much of its character and historic importance to the River of Egypt The accuracy of his statements (roundly scouted in many cases as lies by his time- fellows) has been abundantly proved. See Murray's Life pre- fixed to the 1805 ed. of Bruce'' s Travels iti 1768- 1773; and Playfair's Travels in the Footsteps of Bruce. Mungo Park. — Selkirkshire, 1771 — 1805. One of the heroes of African travel. Educated at Selkirk Grammar School and at University. As gardener at Hammer- smith attracted the notice of Sir Joseph Banks, and after serving as assistant surgeon on board an East Indiaman was sent out by the African Association. In 1796, he reached the Niger at Sego, but after much hardship and danger had to return to England in 1797. On a second expedition, in 1805, he succeeded in making his way down the river from Sansanding to Bussa, where he was slain by the natives. No progress of discovery will put out of date Park's Travels in the Interior Districts of Africa (1799), which, eagerly read at the time for their new facts, are no less attractive still for their ever new human interest. GEOGRAPHICAL EXPLORERS. "William Balfour Baikie. — Kirkwall, 1820 — 1864. M.D. Surgeon in R. N. (from 1848) and African Explorer. On death of Consul Beecroft (1854) took command of the *' Pleiad" expedition to the Kworra and Benue, and afterwards commanded the Niger expedition of 1857, and had charge for several years of the Government Experimental Settlement at Lukoja. He made numerous contributions to African geography and philology. William Scoresby. — Whitby, 1790 — Torquay, 1857. Artie Explorer. Went to sea in his father's ship as a boy, spent winters in study at the University ; after retirement from sea entered the church, D.D., Cambridge. He surveyed a large portion of coast of Greenland, made classical studies of its glacial phenomena, besides valuable observations on magnetism, meteorology, etc. Sir John Richardson. — Dumfries, 1787 — Grasmere, 1865. Arctic Explorer and Naturalist. Graduated as M.D. (1816) at University ; was Surgeon and Naturalist under Franklin in the 1819-22 and 1825-27 expeditions; and in 1847-49 com- manded a Franklin search expedition. Contributed natural history material to the account of Franklin's expeditions, and other works of Arctic travel ; and wrote Fazma Borcali Amcricatia (1831-37). Charles Darwin and other travellers are commemorated elsewhere. GEOLOGISTS. James Hutton. — 1726— 1797. M.D. He early abandoned medicine for agriculture, and devoted the last thirty years of his' life to geological and meteoro- logical studies, the outcome of which was the publication of his famous Theory of the Earth and a Theory of Rain. Hutton taught that all geological phenomena had been the result of forces still in action, by which the crust of the globe would continue to be modified in the future. He deprecated all appeals to imaginary agencies, and maintained that the only sure method of unravelling the past was by first studying the present. He showed that most of the rock-rnasses visible at the earth's surface must have been deposited in the form of gravel, sand, and mud at the bottom of the sea ; that they had not been accumulated continuously, layer above layer, like the coats of an onion, but that now and again the bed of the sea had been elevated, the strata contorted, fractured, and denuded, and again submerged and covered with newer deposits formed out of the debris of older accumulations. He was the first to establish the former molten condition of granite and many other crystal- line rocks ; and he further held that sedimentary strata deeply buried in the earth's crust might, by the combined action of heat and pressure, be converted into crystalline masses, and such, he maintained, was the origin of the crystalline schists of the Highlands, etc. Hutton taught further that the present configuration of the land was due directly to the denuding action of the subaerial forces — rain, frost, rivers, etc. "The moun- tains," he said, "have been formed by the hollowing out of the valleys, and the valleys have been hollowed out by the attrition of hard materials coming from the mountains." Hutton is therefore justly regarded as the founder of the ir.odern system of Geology. GEOLOGISTS. John Playfair. — 1748— 1819. Educated for the Church at St. Andrews ; for some time a minister ; in 1785 Joint-professor of Mathematics in Edinburgh ; in 1805 Professor of Natural Philosophy. In his famous Illustrations of the Hutto7iian Theory he sets forth the geological views of Hutton, and supports them with much originality and acvmien, so giving a great impetus to the study of physical geology. His style, clear and incisive, vigorous, but always under control, vivacious but refined, is a model which later writers on scientific subjects Irave seldom approached and never surpassed. He discerned the glacial origin of the large erratics from the Alps which are scattered over the J^ua, thus anticipating the later generalisations of glacial geology. Sir James Hall. — 1761 — 1832. Author of a work on Gothic Architecture, but best known by his Papers on Experimental Geology in the Trans, of the Roy. Soc, Edinburgh. By ingenious physical experiments, he cor- roborated some of the most disputed doctrines taught by Hutton. His work is still highly appreciated, especially by foreign geologists, by whom he is considered the founder of Experimental Geology. Robert Jameson. — 1774 — 1834. Studied Natural History under Walker in Edinburgh, and subsequently spent two years in Freyberg under the tuition of Werner. In 1804 was appointed to the Chair of Natural History. Was an enthusiastic follower of Werner, and an excellent teacher. Although a disciple of Werner, and opponent of Hutton, he yet modified some of the views held by his master, maintaining that in determining geological formations the evidence supplied by fossil organic remains was as essential as that furnished by mineralogical and petrological characters. He was joint founder with Brewster, and Editor of the Edinburgh Philosophical Magazine, and also founded the Wernerian Society. John MacCulloch.-— 1773— 1835. M.D. Chemist to the Board of Ordnance in 1803. The results of prolonged investigation into the Mineralogy and Petrology of the Western Islands of Scotland placed MacCulloch B lo GEOLOGISTS. in the fronl rank of his geological contemporaries. In 1826, he N\ as commissioned by Government to prepare a Geological Map of Scotland, which was completed, but not published till after his death. He will always be remembered from the fact that he was the first to trace out the distribution of the various rock- masses of Scotland with some approach to accuracy. Sir Thomas Dick Lauder.- 1748— 184S. Author of a Paper On the Parallel Roads of Glenroy and of the well-known Account of the Great Moray Floods of i2>2g, a work still frequently referred to by writers en Physical Geology. Sir William Logan. — Montreal, 1798 — Llechryd, 1875. Studied at High School and University. Associated with Sir Henr}'- de la Beche in the Geological Survey of South Wales Coalfield. Appointed in 1842 to be Director of the Geological Survey of Canada. Author of numerous papers, etc., on Geological subjects. Was the first to point out that the underclays upon which coal- seams rest are ancient soils ; recognized the true position of the Huronian strata, and showed that these are later than a great series of metamorphic rocks, which he designated the Latircntian; was the first to recognize the organic origin of Eozoon Cana- dw-nse ; and in 1871 endowed the Logan Chair of Geology in the M'Gill University. Hugh Falconer. — Forres, 1808 — London, 1865. King's College, Aberdeen, M.A., 1826; Edinburgh, M.D., 1829. In 1830 went to India as an Assistant-Surgeon in II. E. I. C. S. In 1832 Superintendent of the Botanic Gardens at Suharunpoor. In 1847 Professor of Botany in the Calcutta Medical College. Author of many botanical papers relating chiefly to the flora of India. His most important work was the discovery and description of the organic remains of the Sewalik Hills ; was dis- tinguished for his researches on the Quaternary Mammalia of Europe ; and was the foremost palaeontologist of his day in Britain. The Falconer Fellowship was founded in his memor}'. GEOLOGISTS. ii Thomas Oldham. — Dublin, 1816 — Rugby, 1878. Studied at Trinity College and Edinburgh, 1832-1838. Joined Geological Department of the Ordnance Survey of Ire- land in 1839. Director of the Irish Geological Survey in 1846. In 1845 Professor of Geology in the University, Dublin; in 1848 President of the Geo). Soc. of Dublin. In 1850 went to India as vSuperintendent of the Geological Survey there. Oldham's most important works are the reports published by the Geological Survey of India, some of the memoirs in which were personally contributed by him, such as one On the Fossil Flora of the Raj mahal Series^ and his Essay On the Coal Resource's cf India. Edward Forbes. — Isle of Man, 1815 — Edinburgh, 1854. Matriculated in Edinburgh University in 1S31. Author of many papers and works on Natural History. Appointed Paleontologist to the Geological Survey in 1844, and obtained the Chair of Natural History in Edinburgh University in 1854. Forbes's work has greatly influenced the progress of Geology. Girted with a fine imagination and conspicuous for the philo- sophical breadth of his conceptions, he brought his great stores of zoological and botanical knowledge to bear upon many questions in historical geology. His admirable work on the Fhivio-viarine Tertiaries of the Isle of Wight established the order of succession of those deposits, and formed a model for subsequent investigation. But it was by his paper On the Con- nection between the Distribution of the existing Fauna and Flora of the British Islands and the Geological Changes zvhich have affected this area, that Forbes will continue to be best known to geological inquirers. Some of the views advanced in this celebrated memoir have been set aside by later observations, while others have been more or less modified, but the lines of his inquiry, his m.ethods of investigation, the boldness and origin- ality of his conceptions, the philosophical breadth of his general- izations — in a word, his insight into the working of nature are instinct with genius, and will ever be suggestive to those ardent minds, whose instincts impel them to be something more than mere collectors of dry facts. Robert Harkness. — Ormskirk, 1816 — Dublin, 1879. Student, 1833-4. Professor of Geology, Queen's College, Cork, 1853. 12 GEOLOGISTS, His chief papers, published in the Quart. Journ. of the Geol. Soc, relate to the Palaeozoic rocks of the north of England, and the southern uplands of Scotland. He was distinguished for his power of rapidly unravelling the geological structure of a region. Sir Roderick Irnpey Murchison.— Tarradale, Ross-shire, 1792 — Lor don, 187 1. Studied at the Royal Military College, (-veat Marlow, and for a short time at Edinburgh. Became a geologist in middle age. Director-General of the Geological Survey in 1855. Author of more than a hundred papers on Geology, His most important works are The Silurian System^ 1S39 ; The Geology of Russia and the Ural Mountains^ 1845 ; and Siluria, 1854. He defined the Silurian System ai:d the Permian System, and established the fact of a graduated transition from secondary to tertiary rocks in the South-east Alps, etc. ; was the first to recognise that the gneissic rocks of the North-west Highlands of Scotland are the oldest in Britain ; and inferred the presence of auriferous deposits in Australia long years before their actual discovery. Murchison was pre-eminent for the skill with which lie could read the geological structure of a country. Founded the Murchison Chair of Geology and Mineralogy. David Forbes. — Douglas, Isle of Man, 1828— London, 1876. Author of many papers and lectures on Metallurgy, Mineralogy and Geology. His geological papers deal largely with the phy- sico-chemical changes in rocks ; those relating to the origin of foliation being especially suggestive, Forbes travelled much in S. America (1857-1S60), and afterwards published his important paper On the Geology of Bolivia and Southern Peru, in which amongst other interesting conclusions he shows that vast masses of rock have been metamorphosed, and delineates '*the grand cycles of physical and chemical changes which accompany the evolution of mountain-ranges on the grandest scale," John Allan Broun, T. Makdougall Brisbane, John ^Welsh, and other Meteorologists, are also worthy of remembrance. Charles William Wells, James David Forbes, and Charles Darwin arc commemorated elsewhere. ZOOLOGISTS AND BOTANISTS. Erasmus Darwin. — Elton, Nottinghamshire, 1731 — Derby, 1802. Studied Arts in Cambridge, and Medicine in Edinburgh. Endowed with the most extraordinary insight and originality, in his works entitled Zoonomia, or Lazvs of Organic Life and The Botanic Garden^ he anticipated many modern opinions on physiological and pathological questions, predicted the impor- tance of microscopic studies, and gave many other instances of speculative genius and prophetic capacity, contemptuously termed " Darwinising " by his contemporaries. He propounded independently views like those of Goethe and Lamarck, emphasizing the modification of species through function, habit, environment, and heredity, and was the great forerunner of his grandson. His eldest son, Charles (stud. med. 1775-8), died of a dissecting wound at the outset of a career of the most brilliant scientific promise. Charles 'Wm. 'Wells.— Charleston, 1757— London, 1817. M.D., Edinburgh. Chiefly memorable for his classical essay on Deiv, termed by Herschel "one of the most beautiful specimens of inductive experimental inquiry." One of his papers contains an anticipa- tion of the theory of natural selection. Robert Kaye Greville. — Bishop Auckland, 1794 — Edin. 1866. Studied at Edinburgh and London. As collector, systeriiatist, and artist, he added greatly to our knowledge of the cryptogamic lloro, and is commemorated by "Grevillea." 14 ZOOLOGISTS AND BOTANISTS. Robert Brow^n. — Montrose, 1773 — London, 1858, Student, Aberdeen and Edinburgh. Keeper of the Depart- ment of Botany, British Museum. His first great contribution to science was an account of the Flora of New Holland and Van Diemen's Land, which he had visited as exploring naturalist. This and succeeding works began a new era in systematic botany, disclosinsj; the hitherto undetermined affinities of various groups, and finally establishing the Natural System. Uniting power of patient special research with that of broad generalisation, "he unravelled with true morphological insight many structural complexities, such as those of Conifers and Cycads, Orchids and ProteacccC ; and by his anatomiical researches, e.g. on fertilisation, and on the structure of the ovule, and his demonstration of the affinities of the Gymnosperms, earned Humboldt's famous eulogium ■' facile princeps botanicorr.m.' " Robert Grant. — Edin. 1793 — London, 1874. M.D., Edinburgh; Prof. Comp. Anat. and Zool., Univ. Coll., London. He is best known for his researches on the structure and economy of the Sponges. From the first an evolutionist, he taught as early as 1826, that species are descended from other species by persistent modification. Kdward Forbes. — Douglas, Isle of Man, 1815 — Edin. 1S54. Student, Edinburgh and Paris, Prof. Nat. Hist., School of Mines, London, and in Edinburgh. His early labours consisted in the investigation of the fauna and flora of various regions which he visited, such as Algiers, Styria, Aegean Sea, Lycia, etc. His observations were those of a naturalist in the widest sense, and were ever united with generalisations as to the influence of climate, environment, and geological changes on the organisms discussed. He first investi- gated systematically the bathymetrical range of marine organisms, and was one of the earliest and most important students of dis- tribution. As a geologist, he is separately commemorated. ZOOLOGISTS AND BOTANISTS. 15 Sir C. 'Wyville Thomson. — Linlithgow, 1830 — 1882. Professor in Aberdeen (1851) ; Cork (1853) ; Belfast (1854) ; and Edinburgh (1870). Known by researches on Echinoderm embryology, but specially identified with that series of investigations of the fauna of the deep sea, which culminated in the voyage of the Challenger, 1 872- 1 876, Of this expedition he was Scientific Director : wrote accounts of this and former cruises, and was engaged up till his death in editing the " Scientific Results."' Charles Robert Darwin. — Shrewsbury, 1809— Down, Kent, 1882. Student of Natural Science in Edinburgh (1825-27), and in Cambridge (1827-30). Member of the University Plinian Society, to which he contributed his earliest papers. The results of that circunmavigatory voyage in the " Beagle," which he made in 183 1 -6, were embodied in the imperishable Naticralisf s Voyage and in a series of geological and zoological works, among which may be mentioned The Structure and Dis- tribution of Coral Reefs, Geological Observations in South America, and Monograph of the Cirripedia. In 1859 he published the Origin of Species, in which he finally excluded the Linnoean dogma of the constancy of species, and with it the special creation hypo- thesis, shewed systematically that evolution is the niodal explana- tion of the origin of organic beings, and defined the action of various factors in the process, laying special emphasis on Natural Selection. Referring evolution mainly to the interaction of the laws of variation and heredity, he illustrated on the one hand the influence of function and environment in producing modi- fications, and on the other, the operation of natural and sexual selection in preserving and perpetuating them. "All the previously unco-ordinated and often divergent lines of biological research and generalisation were now unified ; all the enigmas of structure and function which refused to be harmonised by the ' type theory ' were solved ; the labours of the systematist, palaeontologist, and the embryologist alike acquired new meaning and importance ; ontogeny found its explanation and complement in phylogeny ; and indeed the whole of biology crystallised around a new centre. " In his later works he extended and applied this supreme generalisation to almost all departments of the natural histor)' sciences. His contributions to botany include not only 1 6 ZOOLOGISTS AND BOTANISTS. important physiological monographs, such as those on Insect- ivorous Plants and on Plant-Movements, or those researches on Flower Fertilisation in which he resuscitated the forgotten labours of Sprengel, and shewed how the forms of. flowers largely result from the various methods of their fertilisation, but those revolutionising conceptions of development and distribution which he applied to vegetable as well as to animal organisms. In his Descent of Man and Variation of Plants and Ajiimals under Domestication, he followed out with the greatest detail certain other lines of research indicated in the Origin of Species^ while in his work on The Expression of the Emotions the far- radiating influence of his doctrines was illustrated in relation to Psychology. Plis works not only furnish a model of patient observation and scientific method, of the minute analyses and vast syntheses which distinguish an ideal naturalist, but have led to that entire change in our conception of the past and future of the world's history which is suggested by the term Evolution.
