1859-1863] MAN 239 



will answer. 1 Lyell has been, I fear, rather rash to enter on a Letter 164 



subject on which he of course knows nothing by himself. By 



heavens, Owen will shake himself, when he sees what an 



antagonist he has made for himself in you. With hearty 



admiration, Farewell. 



I am fearfully disappointed at Lyell's excessive caution 2 



in expressing any judgment on Species or [on the] origin of 



Man. 



To John Scott. Letter 165 



Down, March 6th, 1863. 



I thank you for your criticisms on the Origin, and which 



I have not time to discuss ; but I cannot help doubting, 



from your expression of an " innate . . selective principle," 



whether you fully comprehend what is meant by Natural 



Selection. Certainly when you speak of weaker (i.e. less 



well adapted) forms crossing with the stronger, you take a 



widely different view from what I do on the struggle for 



existence ; for such weaker forms could not exist except by 



the rarest chance. With respect to utility, reflect that ^nfths 



part of the structure of each being is due to inheritance of 



formerly useful structures. Pray read what I have said on 



"correlation." Orchids ought to show us how ignorant we 



are of what is useful. No doubt hundreds of cases could be 



advanced of which no explanation could be offered ; but I 



must stop. Your letter has interested me much. I am very 



far from strong, and have great fear that I must stop all work 



for a couple of months for entire rest, and leave home. It 



will be ruin to all my work. 



To J. D. Hooker. Letter 166 



Down, April 23rd [1S63]. 



The more I think of Falconer's letter 3 the more grieved I 

 am ; he and Prestwich (the latter at least must owe much to 



which he used in illustration of his statements "the cerebral hemispheres 

 had glided forward and apart behind so as to expose a portion of the 

 cerebellum." 



1 Lyell's answer was in the Athencewn, March 7th, 1863.

3 Published in the A/hena-um, April 4th, 1S63, p. 459. The writer 

 asserts that Lyell did not make it clear that certain material made use of 

 in the Antiquity of Man was supplied by the original work of Mr. Prestwid* 

 and himself. (See Life and Letters, III., p. 19.)
