got the Essay. The parts which I read in sheets seemed to> 

 me grand, especially the generalization about the Australian- 

 flora itself. How superior to Robert Brown's celebrated 

 essay ! I have not seen Naudin's paper,* and shall not be 

 able till I hunt the libraries. I am very anxious to see it. 

 Decaisne seems to think he gives my whole theory. I do 

 not know when I shall have time and strength to grapple- 

 with Hooker. . . . 



P.S. I have heard from Sir W. Jardine :f 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 authority), 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.

t Jardine, Sir William, Bart., 

 b. 1800, d. 1874, was the son of 

 Sir A. Jardine of Applegarth, Dum- 

 friesshire. 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 Or- 

 nithology,' and edited the ' Na- 

 turalist's Library,' in 40 vols, which 

 included the four branches : Mam- 

 malia, Ornithology, Ichthyology, 

 and Entomology. Of these 40 vols. 

 14 were written by himself. In 



1836 he became editor of the ' Maga- 

 zine of Zoology and Botany,' which,, 

 two years later, was transformed 

 into ' Annals of Natural History,' 

 but remained under his direction. 

 For Bonn'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 Annandale,' ' Me- 

 moirs of the late Hugh Strickland,' 

 ' Contributions to Ornithology,' 

 c Ornithological Synonyms,' &c.
