IQ2 SPREAD OF EVOLUTION. [1863. 



C. Danvin to Camille Dareste* 



Down, Feb. 16 [1863]. 



DEAR AND RESPECTED SIR. I thank you sincerely for 

 your letter and your pamphlet. I had heard (I think in one 

 of M. Quatrefage's books) of your work, and was most 

 anxious to read it, but did not know where to find it. You 

 could not have made me a more valuable present. I have 

 only just returned home, and have not yet read your work ; 

 when I do if I wish to ask any questions I will venture to 

 trouble you. Your approbation of my book on Species has 

 gratified me extremely. Several naturalists in England, 

 North America, and Germany, have declared that their 

 opinions on the subject have in some degree been modified, 

 but as far as I know, my book has produced no effect what-

 very kind expression of approbation. Pray believe me, dear 

 Sir, with much respect, 



Yours faithfully and obliged, 



CH. DARWIN. 



C. Darwin to J. D. Hooker.

 not seen the Athenceum,\ but I have sent for it, and may get 

 it to-morrow ; and will then say what I think.

 was in 1863 living at Lille, but has since then been called to Paris. My 

 father took a special interest in Dareste's work on the production of mon- 

 sters, as bearing on the causes of variation. 



f In the 'Antiquity of Man,' first edition, p. 480, Lyell criticised some- 

 what severely Owen's account of the difference between the Human and 

 Simian brains. The number of the Athenceum here referred to (1863, p. 

 262) contains a reply by Professor Owen to Lyell's strictures. The sur- 

 prise expressed by my father was at the revival of a controversy which 

 every one believed to be closed. Prof. Huxley (Medical Times, Oct. 25,
