This series is founded upon a course of popular Universitv 

 lectures given during the winter of ISD'^'-o, in connection witli 

 the opening of the new department of Biology in Colunibia 

 College. The lectures are in a measure consecutive in charac- 

 ter, illustrating phases in the discovery and ai>[»lication of tlie 

 theory of Evolution. Thus the tirst course outlined the de- 

 velopment of the Descent theory; the second, the a]>]»licati(>n 

 of this theory to the problem of the ancestry of the Vertebrates, 

 largely based upon embryological data; the third, the applica- 

 tion of the Descent theory to the interpretation of the structure 

 and phylogeny of the Fishes or lowest Vertebrates, cliietly based 

 upon comparative anatomy ; the fourth, u])on the problems of 

 individual development and Inheritance, chiefly based upon the 

 structure and functions of the cell. 



Since their original delivery the lectures have been carofully 

 rewritten and illustrated so as to adapt them to the use of (\d- 

 lege and University students and of general readers. The vol- 

 umes as at present arranged for include:
