Xll PREFACE 



reward is full payment for all his labour and 

 pains. 



" Man's Place in Nature," perhaps, may still 

 be useful as an introduction to the subject ; but, 

 as any interest which attaches to it must be 

 mainly historical, I have thought it right to 

 leave the essays untouched. The history of the 

 long controversy about the structure of the brain, 

 following upon the second dissertation, in the 

 original edition, however, is omitted. The verdict 

 of science has long since been pronounced upon 

 the questions at issue ; and no good purpose can 

 be served by preserving the memory of the details 

 of the suit. 



In many passages, the reader who is acquainted 

 with the present state of science, will observe 

 much room for addition; but, in all cases, the 

 supplements required, are, I believe, either in- 

 different to the argument or would strengthen ifc.
