LETTER 155. TO HUGH FALCONER.

(155/1. The original letter is dated "December 10th," but this must, we think, be a slip of the pen for January 10th. It contains a reference to No. VI. of the "Lectures to Working Men" which, as Mr. Leonard Huxley is good enough to inform us, was not delivered until December 15th, and therefore could not have been seen by Mr. Darwin on December 10th. The change of date makes comprehensible the reference to Falconer's paper "On the American Fossil Elephant of the Regions bordering the Gulf of Mexico (E. Columbi, Falc.)," which appeared in the January number of the "Natural History Review." It is true that he had seen advanced sheets of Falconer's paper ("Life and Letters," II., page 389), but the reference here is to the complete paper.

In the present volume we have thought it right to give some expression to the attitude of Darwin towards Owen. Professor Owen's biographer has clearly felt the difficulty of making a statement on Owen's attitude towards Darwinism, and has ("Life of Sir Richard Owen," Volume II., page 92) been driven to adopt the severe indictment contained in the "Origin of Species," Edition VI., page xviii. Darwin was by no means alone in his distrust of Owen; and to omit altogether a reference to the conduct which led up to the isolation of Owen among his former friends and colleagues would be to omit a part of the history of science of the day. And since we cannot omit to notice Darwin's point of view, it seems right to give the facts of a typical case illustrating the feeling with which he regarded Owen. This is all the more necessary since the recently published biography of Sir R. Owen gives no hint, as far as we are aware, of even a difference of opinion with other scientific men.

The account which Falconer gives in the above-mentioned paper in the "Nat. Hist. Review" (January, 1863) would be amusing if the matter were less serious. In 1857 Falconer described ("Quart. Journ. Geol. Soc." XIII.) a new species of fossil elephant from America, to which he gave the name Elephas Columbi, a designation which was recognised and adopted by Continental writers. In 1858 (Brit. Assoc. Leeds) Owen made use of the name "Elephas texianus," Blake" for the species which Falconer had previously named E. Columbi, but without referring to Falconer's determination; he gave no authority, "thus by the established usage in zoology producing it as his own." In 1861 Owen in his Palaeontology, 2nd edition, 1861, describes the elephant as E. texianus, Blake. To Mr. Blake's name is appended an asterisk which refers to a footnote to Bollaert's "Antiquities of S. America," 2nd edition. According to Falconer (page 46) no second edition of Bollaert had appeared at the time of writing (August, 1862), and in the first edition (1860) he was "unable to detect the occurrence of the name even, of E. texianus, anywhere throughout the volume"; though Bollaert mentions the fact that he had deposited, in the British Museum, the tooth of a fossil elephant from Texas.

In November, 1861, Blake wrote a paper in the "Geologist" in which the new elephant no longer bears his own name as authority, but is described as "Elephas texianus, Owen, E. Columbi, Falconer." Finally, in another paper the name of Owen is dropped and the elephant is once more his own. As Falconer remarks, "the usage of science does not countenance such accommodating arrangements, when the result is to prejudice a prior right."

It may be said, no doubt, that the question who first described a given species is a petty one; but this view has a double edge, and applies most strongly to those who neglect the just claims of their predecessors.

Down, January 5th [1863].

I finished your Elephant paper last night, and you must let me express my admiration at it. (155/2. "On the American Fossil Elephant of the Regions bordering the Gulf of Mexico (E. Columbi, Falc.), etc." "Nat. Hist. Rev." 1863, page 81. (Cf. Letter to Lyell. "Life and Letters," II., page 389; also "Origin," Edition VI., page 306.) See Letter 143.) All the points strike me as admirably worked out, and very many most interesting. I was particularly struck with your remarks on the character of the ancient Mammalian Fauna of N. America (155/3. Falconer, page 62. This passage is marked in Darwin's copy.); it agrees with all I fancied was the case, namely a temporary irruption of S. American forms into N. America, and conversely, I chuckled a little over the specimen of M. Andium "hesitating" between the two groups. (155/4. In speaking of the characters of Mastodon Andium, Falconer refers to a former paper by himself ("Quart. Journ. Geol. Soc." Volume XIII. 1857, page 313), in which he called attention "to the exceptional character of certain specimens of M. Andium, as if hesitating between [the groups] Tetralophodon and Trilophodon" (ibid., page 100).) I have been assured by Mr. Wallace that abundant Mastodon remains have been found at Timor, and that is rather close to Australia. I rejoice that you have smashed that case. (155/5. In the paper in the "Nat. Hist. Review" (loc. cit.) Falconer writes: "It seems more probable that some unintentional error has got mixed up with the history of this remarkable fossil; and until further confirmatory evidence is adduced, of an unimpeachable character, faith cannot be reposed in the reality of the asserted Australian Mastodon" (page 101).) It is indeed a grand paper. I will say nothing more about your allusions to me, except that they have pleased me quite as much in print as in MS. You must have worked very hard; the labour must have been extreme, but I do hope that you will have health and strength to go on. You would laugh if you could see how indignant all Owen's mean conduct about E. Columbi made me. (155/6. See Letter 157.) I did not get to sleep till past 3 o'clock. How well you lash him, firmly and severely, with unruffled temper, as if you were performing a simple duty. The case is come to such a pass, that I think every man of science is bound to show his feelings by some overt act, and I shall watch for a fitting opportunity.

P.S.--I have kept back for a day the enclosed owing to the arrival of your most interesting letter. I knew it was a mere chance whether you could inform me on the points required; but no one other person has so often responded to my miscellaneous queries. I believe I have now in my greenhouse L. trigynum (155/7. Linum trigynum.), which came up from seed purchased as L. flavum, from which it is wholly different in foliage. I have just sent in a paper on Dimorphism of Linum to the Linnean Society (155/8. "On the Existence of the Forms, and on their reciprocal Sexual Relation, in several species of the genus Linum.--"Journ. Linn. Soc."
