The Wallace-Darwin Correspondence 



Australian papers and New Zealand might also publish 

 them, and then you would have a fine basis to go on. 



Is your essay on Variation in Man to be a supplement 

 to your volume on Domesticated Animals and Cultivated 

 Plants ? I would rather see your second volume on " The 

 Struggle for Existence, etc.," for I doubt if we have a 

 sufficiency of fair and accurate facts to do anything with 

 man. Huxley, I believe, is at work upon it. 



I have been reading Murray's volume on the Geographi- 

 cal Distribution of Mammals. He has some good ideas 

 here and there, but is quite unable to understand Natural 

 Selection, and makes a most absurd mess of his criticism 

 of your views on oceanic islands. 



By the bye, what an interesting volume the whole of 

 your materials on that subject would, I am sure, make. — 

 Yours very sincerely, Alfred R. Wallace. 



Down, Bromley, Kent, S.E. March, 1867. 



My dear Wallace, — I thank you much for your two 

 notes. The case of Julia Pastrana' is a splendid addition 

 to my other cases of correlated teeth and hair, and I will 

 add it in correcting the proof of my present volume. Pray 

 let me hear in course of the summer if you get any evidence 

 about the gaudy caterpillars. I should much like to give 

 (or quote if published) this idea of yours, if in any way 

 supported, as suggested by you. It will, however, be a long 

 time hence, for I can see that sexual selection is growing 

 into quite a large subject, which I shall introduce into my 

 essay on Man, supposing that I ever publish it. 



I had intended giving a chapter on Man, inasmuch as 

 many call him (not quite truly) an eminently domesticated 

 animal; but I found the subject too large for a chapter.
