 grapple with Hooker. . . . 



P. S. I have heard from Sir W. Jardine : * his criticisms 

 are quite unimportant ; some of the Galapagos so-called 

 species ought to be called varieties, which I fully expected ; 

 some of the sub-genera, thought to be wholly endemic, have 

 been found on the Continent (not that he gives his author- 

 ity), but I do not make out that the species are the same. 

 His letter is brief and vague, but he says he will write again. 



C. Darwin to J. D. Hooker. 



Down [23rd December, 1859]. 



MY DEAR HOOKER, I received last night your * Intro- 

 duction,' for which very many thanks ; I am surprised to see 

 how big it is : I shall not be able to read it very soon. It 

 was very good of you to send Naudin, for I was very curi- 

 ous to see it. I am surprised that Decaisne should say it 

 was the same as mine. Naudin gives artificial selection, as 

 well as a score of English writers, and when he says species 

 were formed in the same manner, I thought the paper would 



* Jardine, Sir William, Bart., b. 1800, d. 1874, was the son of Sir A. 

 Jardine of Applegarth, Dumfriesshire. He was educated at Edinburgh, 

 and succeeded to the title on his father's decease in 1821. He published, 

 jointly with Mr. Prideaux J. Selby, Sir Stamford Raffles, Dr. Horsfield, 

 and other ornithologists, ' Illustrations of Ornithology,' and edited the 

 ' Naturalist's Library,' in 40 vols., which included the four branches : 

 Mammalia, Ornithology, Ichnology, and Entomology. Of these 40 vols. 

 14 were written by himself. In 1836 he became editor of the ' Magazine 

 of Zoology and Botany,' which, two years later, was transformed into 

 'Annals of Natural History,' but remained under his direction. For 

 Bohn's Standard Library he edited White's ' Natural History of Selborne.' 

 Sir W. Jardine was also joint editor of the * Edinburgh Philosophical 

 Journal,' and was author of ' British Salmonidae,' ' Ichthyology of Annan- 

 dale,' ' Memoirs of the late Hugh Strickland,' 'Contributions to Ornithol- 

 ogy,' ' Ornithological Synonyms,' &c. (Taken from Ward, ' Men of the 

 Reign,' and Gates, 'Dictionary of General Biography.')
