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 T 9 <j 9 ^ths 

 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 [1863]. 



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 Athentzum, March 7th, 1863. 



2 In the Antiquity of Man : see Life and Letters, III., p. 8. 



3 Published in the Athenceum, April 4th, 1863, p. 459. The writer 

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

 in the Antiquity of Alan was supplied by the original work of Mr. Prestwich 

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