Chapter CDXIV: Letter 782: TO ANTHONY RICH. Down, February 4th, 1882 (1)

It is always a pleasure to me to receive a letter from you. I am very sorry to hear that you have been more troubled than usual with your old complaint. Any one who looked at you would think that you had passed through life with few evils, and yet you have had an unusual amount of suffering. As a turnkey remarked in one of Dickens' novels, "Life is a rum thing." (782/1. This we take to be an incorrect version of Mr. Roker's remark (in reference to Tom Martin, the Butcher), "What a rum thing Time is, ain't it, Neddy?" ("Pickwick," Chapter XLII.). A careful student finds that women are also apostrophised as "rum": see the remarks of the dirty-faced man ("Pickwick," Chapter XIV.).) As for myself, I have been better than usual until about a fortnight ago, when I had a cough, and this pulled me down and made me miserable to a strange degree; but my dear old wife insisted on my taking quinine, and, though I have very little faith in medicine, this, I think, has done me much good. Well, we are both so old that we must expect some troubles: I shall be seventy-three on Feb. 12th. I have been glad to hear about the pine-leaves, and you are the first man who has confirmed my account that they are drawn in by the base, with a very few exceptions. (782/2. "The Formation of Vegetable Mould through the Action of Worms," 1881, page 71.) With respect to your Wandsworth case, I think that if I had heard of it before publishing, I would have said nothing about the ledges (782/3. "Ledges of Earth on Steep Hill-sides" (ibid., page 278).); for the Grisedale case (782/4. "The steep, grass-covered sides of a mountainous valley in Westmorland, called Grisedale, were marked in many places with innumerable, almost horizontal, little ledges...Their formation was in no way connected with the action of worms (and their absence is an inexplicable fact)...(ibid., page 282.), mentioned in my book and observed whilst I was correcting the proof-sheets, made me feel rather doubtful. Yet the Corniche case (782/5. Ibid., page 281.) shows that worms at least aid in making the ledges. Nevertheless, I wish I had said nothing about the confounded ledges. The success of this worm book has been almost laughable. I have, however, been plagued with an endless stream of letters on the subject; most of them very foolish and enthusiastic, but some containing good facts, which I have used in correcting yesterday the "sixth Thousand."

Your friend George's work about the viscous state of the earth and tides and the moon has lately been attracting much attention (782/6. Published in the "Philosophical Transactions of the Royal Society," 1879, 1880, 1881.), and all the great judges think highly of the work. He intends to try for the Plumian Professorship of Mathematics and Natural Philosophy at Cambridge, which is a good and honourable post of about 800 pounds a year. I think that he will get it (782/7. He was elected Plumian Professor of Astronomy and Experimental Philosophy in 1883.) when Challis is dead, and he is very near his end. He has all the great men--Sir W. Thomson, Adams, Stokes, etc.--on his side. He has lately been chief examiner for the Mathematical Tripos, which was tremendous work; and the day before yesterday he started for Southampton for a five-weeks' tour to Jamaica for complete rest, to see the Blue Mountains, and escape the rigour of the early spring. I believe that George will some day be a great scientific swell. The War Office has just offered Leonard a post in the Government Survey at Southampton, and very civilly told him to go down and inspect the place, and accept or not as he liked. So he went down, but has decided that it would not be worth his while to accept, as it would entail his giving up his expedition (on which he had been ordered) to Queensland, in Australia, to observe the Transit of Venus. (782/8. Major Leonard Darwin, late R.E., served in several scientific expeditions, including the Transits of Venus of 1874 and 1882.) Dear old William at Southampton has not been very well, but is now better. He has had too much work--a willing horse is always overworked--and all the arrangements for receiving the British Association there this summer have been thrown on his shoulders.

But, good Heavens! what a deal I have written about my sons. I have had some hard work this autumn with the microscope; but this is over, and I have only to write out the papers for the Linnean Society. (782/9. i. "The Action of Carbonate of Ammonia on the Roots of Certain plants." [Read March 16th, 1882.] "Journ. Linn. Soc." Volume XIX., 1882, page 239. ii. "The Action of Carbonate of Ammonia on Chlorophyll-bodies." [Read March 6th, 1882.] Ibid., page 262.) We have had a good many visitors; but none who would have interested you, except perhaps Mrs. Ritchie, the daughter of Thackeray, who is a most amusing and pleasant person. I have not seen Huxley for some time, but my wife heard this morning from Mrs. Huxley, who wrote from her bed, with a bad account of herself and several of her children; but none, I hope, are at all dangerously ill. Farewell, my kind, good friend.

Many thanks about the picture, which if I survive you, and this I do not expect, shall be hung in my study as a perpetual memento of you.

(782/10. The concluding chapter of the "Life and Letters" gives some account of the gradual failure in health which was perceptible in the last year of Mr. Darwin's life. He died on April 19th, 1882, in his 74th year.)

Agassiz, Louis Jean Rodolphe (1807-73): entered a college at Bienne at the age of ten, and from 1822 to 1824 he was a student at the Academy of Lausanne. Agassiz afterwards spent some years as a student in the Universities of Zurich, Heidelberg, and Munich, where he gained a reputation as a skilled fencer. It was at Heidelberg that his studies took a definite turn towards Natural History. He took a Ph.D. degree at Erlangen in 1829. Agassiz published his first paper in "Isis" in 1828, and for many years devoted himself chiefly to Ichthyology. During a visit to Paris he became acquainted with Cuvier and Alexander von Humboldt; in 1833, through the liberality of the latter, he began the publication of his "Recherches sur les Poissons Fossiles," and in 1840 he completed his "Etudes sur les Glaciers." In 1846 Agassiz went to Boston, where he lectured in the Lowell Institute, and in the following year became Professor of Geology and Zoology at Cambridge. During the last twenty-seven years of his life Agassiz lived in America, and exerted a great influence on the study of Natural History in the United States. In 1836 he received the Wollaston Medal of the Geological Society of London, and in 1861 he was selected for the Copley Medal of the Royal Society. In 1873 Agassiz dictated an article to Mrs. Agassiz on "Evolution and Permanence of Type," in which he repeated his strong conviction against the views embodied in the "Origin of Species." See "Life, Letters, and Works of Louis Agassiz," by Jules Marcou, 2 volumes, New York, 1896; "Louis Agassiz: his Life and Correspondence," edited by Elizabeth Cary Agassiz, 2 volumes, London, 1885; "Smithsonian Report," 1873, page 198. -attack on "Origin." -Darwin's criticism of book on Brazil. -Darwin's opinion of. -views on creation of species. -on geographical distribution. -"Methods of Study" by. -misstatement of Darwin's views. -Walsh on. -"Etudes sur les Glaciers." -Darwin on glacier work of. -on glaciers in Ceara Mts. -glacier-ice-lake theory of Parallel Roads of Glen Roy. -on glacier moraines. -on rock-cavities formed by glacier-cascades. -on Darwin's theory. -on Geology of the Amazons. -doubts recent upheaval of Patagonia. -mentioned.

Barrande, Joachim (died 1883): devoted himself to the investigation of the Palaeozoic fossils of Bohemia, his adopted country. His greatest work was the "Systeme Silurien de la Boheme," of which twenty-two volumes were published before his death. He was awarded the Wollaston Medal of the Geological Society in 1855. Barrande propounded the doctrine of "colonies." He found that in the Silurian strata of Bohemia, containing a normal succession of fossils, exceptional bands occurred which yielded fossils characteristic of a higher zone. He named these bands "colonies," and explained their occurrence by supposing that the later fauna represented in these "precursory bands" had already appeared in a neighbouring region, and that by some means communication was opened at intervals between this region and that in which the normal Silurian series was being deposited. This apparent intercalation of younger among older zones has now been accounted for by infoldings and faulting of the strata. See J.E. Marr, "On the Pre- Devonian Rocks of Bohemia," "Quart. Journ. Geol. Soc." Volume XXXVI., page 591 (1880); also "Defense des Colonies," by J. Barrande (Prag, 1861), and Geikie's "Text-book of Geology" (1893), page 773. -candidature for Royal medal. -candidate for Royal Society foreign list. -work on Colonies. -Lyell on work of.

Bates, Henry Walter (1825-92): was born at Leicester, and after an apprenticeship in a hosiery business he became a clerk in Allsopp's brewery. He did not remain long in this uncongenial position, for in 1848 he embarked for Para with Mr. Wallace, whose acquaintance he had made at Leicester some years previously. Mr. Wallace left Brazil after four years' sojourn, and Bates remained for seven more years. He suffered much ill- health and privation, but in spite of adverse circumstances he worked unceasingly: witness the fact that his collection of insects numbered 14,000 specimens. He became Assistant Secretary to the Royal Geographical Society in 1864, a post which he filled up to the time of his death in 1892. In Mr. Clodd's interesting memoir prefixed to his edition of the "Naturalist on the Amazons," 1892, the editor pays a warm and well-weighed tribute to Mr. Bates's honourable and lovable personal character.

Beaumont, Elie de (1798-1874): was a pupil in the Ecole Polytechnique and afterwards in the Ecole des Mines. In 1820 he accompanied M. Brochant de Villiers to England in order to study the principles of geological mapping, and to report on the English mines and metallurgical establishments. For several years M. de Beaumont was actively engaged in the preparation of the geological map of France, which was begun in 1825, and in 1835 he succeeded M. B. de Villiers in the Chair of Geology at the Ecole des Mines. In 1853 he was elected Perpetual Secretary of the French Academy, and in 1861 he became Vice-President of the Conseil General des Mines and a Grand Officer of the Legion of Honour. Elie de Beaumont is best known among geologists as the author of the "Systemes des Montagnes" and other publications, in which he put forward his theories on the origin of mountain ranges and on kindred subjects.

Bentham, George (1800-83): son of Sir Samuel Bentham, and nephew of Jeremy, the celebrated authority on jurisprudence. Sir Samuel Bentham was at first in the Russian service, and afterwards in that of his own country, where he attained the rank of Inspector-General of Naval Works. George Bentham was attracted to botany during a "caravan tour" through France in 1816, when he set himself to work out the names of flowers with De Candolle's "Flore Francaise." During this period he entered as a student of the Faculte de Theologie at Tours. About 1820 he was turned to the study of philosophy, probably through an acquaintance with John Stuart Mill. He next became the manager of his father's estates near Montpellier, and it was here that he wrote his first serious work, an "Essai sur la Classification des Arts et Sciences." In 1826 the Benthams returned to England, where he made many friends, among whom was Dr. Arnott; and it was in his company that Bentham, in 1824, paid a long visit to the Pyrenees, the fruits of which was his first botanical work, "Catalogue des Plantes indigenes des Pyrenees, etc." 1826. About this time Bentham entered Lincoln's Inn with a view to being called to the Bar, but the greater part of his energies was given to helping his Uncle Jeremy, and to independent work in logic and jurisprudence. He published his "Outlines of a New System of Logic" (1827), but the merit of his work was not recognised until 1850. In 1829 Bentham finally gave up the Bar and took up his life's work as a botanist. In 1854 he presented his collections and books (valued at 6,000 pounds) to the Royal Gardens, Kew, and for the rest of his life resided in London, and worked daily at the Herbarium. His work there began with the "Flora of Hong Kong," which was followed by that of Australia published in 1867 in seven volumes octavo. At the same time the "Genera Plantarum" was being planned; it was begun, with Dr. Hooker as a collaborator, in 1862, and concluded in 1883. With this monumental work his labours ended; "his strength...suddenly gave way...his visits to Kew ended, and lingering on under increasing debility, he died of old age on September 10th last" (1883.) The amount of work that he accomplished was gigantic and of the most masterly character. In speaking of his descriptive work the writer (Sir J.D. Hooker) of the obituary notice in "Nature" (October 2nd, 1884), from which many of the above facts are taken, says that he had "no superior since the days of Linnaeus and Robert Brown, and he has left no equal except Asa Gray" ("Athenaeum," December 31st, 1850; "Contemporary Review," May, 1873; "George Bentham, F.R.S."

Berkeley, Miles Joseph (1803-89): was educated at Rugby and Christ's College, Cambridge; he took orders in 1827. Berkeley is described by Sir William Thiselton-Dyer as "the virtual founder of British Mycology" and as the first to treat the subject of the pathology of plants in a systematic manner. In 1857 he published his "Introduction to Cryptogamic Botany." ("Annals of Botany," Volume XI., 1897, page ix; see also an obituary notice by Sir Joseph Hooker in the "Proc.

Binney, Edward William F.R.S. (1812-81): contributed numerous papers to the Royal, Palaeontographical, Geological, and other Societies, on Upper Carboniferous and Permian Rocks; his most important work deals with the internal structure of Coal-Measure plants. In a paper "On the Origin of Coal," published in the "Memoirs of the Manchester Literary and Philosophical Society," Volume VIII., page 148, in 1848, Binney expressed the view that the sediments of the Coal Period were marine rather than estuarine, and were deposited on the floor of an ocean, which was characterised by a "uniformity and shallowness unknown" in any oceanic area of the present day. -on marshes of Coal period. -on coal and coal plants.

Blyth, Edward (1810-73): distinguished for his knowledge of Indian birds and mammals. He was for twenty years Curator of the Museum of the Asiatic Society of Bengal, a collection which was practically created by his exertions. Gould spoke of him as "the founder of the study" of Zoology in India. His published writings are voluminous, and include, in addition to those bearing his name, numerous articles in the "Field, Land and Water," etc., under the signature "Zoophilus" or "Z." He also communicated his knowledge to others with unsparing generosity, yet-- doubtless the chief part of his "extraordinary fund of information" died with him. Darwin had much correspondence with him, and always spoke of him with admiration for his powers of observation and for his judgment. The letters to Blyth have unfortunately not come into our hands. The indebtedness of Darwin to Blyth may be roughly gauged by the fact that the references under his name in the index to "Animals and Plants" occupy nearly a column. For further information about Blyth see Grote's introduction to the "Catalogue of Mammals and Birds of Burma, by the late E. Blyth" in the "Journal of the Asiatic Society of Bengal," Part II., Extra number, August 1875; also an obituary notice published at the time of his death in the "Field." Mr. Grote's Memoir contains a list of Blyth's writings which occupies nearly seven pages of the "Journal." We are indebted to Professor Newton for calling our attention to the sources of this note. -reference to letter from. -visits Down. -on Gallinaceae.

Blytt, Axel Gudbrand (1843-98): the son of the well-known systematist M.N. Blytt. He was attached to the Christiania Herbarium in 1865, and in 1880 became Professor of Botany in the University. His best-known work is the essay referred to above, but he was also known for purely systematic work in Botany as well as for meteorological and geological contributions to science. The above facts are taken from C. Holtermann's obituary notice in the "Berichte der Deutschen Bot. Gesell."

Buckland, William (1784-1856): became a scholar of Corpus Christi College, Oxford, in 1801; in 1808 he was elected Fellow and ordained priest. Buckland travelled on horseback over a large part of the south-west of England, guided by the geological maps of William Smith. In 1813 he was appointed to the Chair of Mineralogy at Oxford, and soon afterwards to a newly created Readership in Geology. In 1823 the "Reliquiae Diluvianae" was published, a work which aimed at supporting the records of revelation by scientific investigations. In 1824 Buckland was President of the Geological Society, and in the following year he left Oxford for the living of Stoke Charity, near Whitchurch, Hampshire. "The Bridgewater Treatise" appeared in 1836. In 1845 Buckland was appointed Dean of Westminster; he was again elected president of the Geological Society in 1840, and in 1848 he received the Wollaston medal. An entertaining account of Buckland is given in Mr. Tuckwell's "Reminiscences of Oxford," London, 1900, page 35, with a reproduction of the portrait from Gordon's "Life of Buckland." -on Glen Roy. -mentioned.

Bunbury, Sir Charles James Fox, Bart. (1809-85): was born at Messina in 1809, and in 1829 entered Trinity College, Cambridge. At the end of 1837 he went with Sir George Napier to the Cape of Good Hope, and during a residence there of twelve months Bunbury devoted himself to botanical field-work, and afterwards (1848) published his "Journal of a Residence at the Cape of Good Hope." In 1844 Bunbury married the second daughter of Mr. Leonard Horner, Lady Lyell's sister. In addition to several papers dealing with systematic and geographical Botany Bunbury published numerous contributions on palaeobotanical subjects, a science with which his name will always be associated as one of those who materially assisted in raising the study of Fossil Plants to a higher scientific level. His papers on fossil plants were published in the "Journal of the Geological Society" between 1846 and 1861, and shortly before his death a collection of botanical observations made in South Africa and South America was issued in book form in a volume entitled "Botanical Fragments" (London, 1883). Bunbury was elected into the Royal Society in 1851, and from 1847 to 1853 he acted as Foreign Secretary to the Geological Society. "Life, Letters, and Journals of Sir Charles J.F.

Candolle, Alphonse Louis Pierre Pyramus De (1806-93): was the son of Augustin Pyramus, and succeeded his father as Professor of Botany at Geneva in 1835. He resigned his Chair in 1850, and devoted himself to research for the rest of his life. At the time of his father's death, in 1841, seven volumes of the "Prodromus" had appeared: Alphonse completed the seventeenth volume in 1873. In 1855 appeared his "Geographie botanique raisonnee," "which was the most important work of his life," and if not a precursor, "yet one of the inevitable foundation-stones" of modern evolutionary principles. He also wrote "Histoire des Savants," 1873, and "Phytographie," 1880. He was lavish of assistance to workers in Botany, and was distinguished by a dignified and charming personality. (See Sir W.

Croll, James (1821-90): was born at Little Whitefield, in Perthshire. After a short time passed in the village school, he was apprenticed as a wheelwright, but lack of strength compelled him to seek less arduous employment, and he became agent to an insurance company. In 1859 he was appointed keeper in the Andersonian University and Museum, Glasgow. His first contribution to science was published in the "Philosophical Magazine" for 1861, and this was followed in 1864 by the essay "On the Physical Cause of the Change of Climate during the Glacial Period." From 1867 to 1881 he held an appointment in the department of the Geological Survey in Edinburgh. In 1876 Croll was elected a Fellow of the Royal Society. His last work, "The Philosophical Basis of Evolution," was published in the year of his death.
