X Suggestions for Fiittire Study 201 



with the living world. In this process of scientific imagina- 

 tion let the student by all means exami7ie himself ; he 

 will thus not only find how little he knows more surely than 

 on more customary methods, but feel keener interest in 

 filling up the blanks in his knowledge ; nay, even make 

 far more rapid and more permanent progress, since we 

 remember what we want to know far better than what we 

 get without asking. This habit learned, the student may, 

 with increasing advantage, direct his own further studies. 



Evolution. — The student who has thus from the outset 

 been at the evolutionary standpoint will have little difficulty 

 in continuing his reading. Summaries which may be of 

 service in reading the Origin of Species and other essential 

 literature of the subject, together with some outline of the 

 state of contemporary discussion, will be found in the 

 writer's articles Darwinian Theory and Evolution of 

 Chambers's Encyclopcedia, and VARIATION AND Selection 

 of the E7icycIopcEdia B^itajutica, Mr. Wallace's Dar- 

 winism and Dr. de Varigny's Experimental Evolution^ 

 both already mentioned, notably of course also IMr. Romanes' 

 Darwin and After Darwin^ may next be read ; and from 

 these it is easy to gather references to the remaining (often 

 more or less anti-Darwinian) literature. But in this, more 

 than in any previous field of study, the student will need to 

 keep his own faculties, observant, critical, and reasoning, 

 fully alive.
