 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.

 pHed 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
