ature pertaining to Organic Evolution. The number of books and articles 
is very extensive, and I have undertaken to sift from the great number a 
limited list of the more meritorious. Owing to the prevalent vagueness 
regarding evolution theories, one is likely to read only about Darwin and 
Darwinism. This should be avoided by reading as a minimum some good 
reference on Lamarck, Weismann, and De Vries, as well as on Darwin. 
It is well enough to begin with Darwin’s Theory, but it is not best to take 
his Origin of Species as the first book. To do this is to place oneself fifty

plied since 1859, and a better conception of Darwin’s Theory can be ob- 
tained by reading first Romanes’s Darwin and After Darwin, vol. I. This to 
be followed by Wallace’s Darwinism, and, thereafter, the Origin of Species
