Note. Since the four succeeding chapters deal with the Evolution
Theory, it maybe worth while to make a few general comments on the
literature 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 years in the past. The evidences of Organic
Evolution have greatly multiplied since 1859, and a better conception
of Darwin's Theory can be obtained 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 may be taken up. These will
give a good conception of Darwin's Theory, and they should be followed
by reading in the order named: Packard's Lamarck; Weismann's The
Evolution Theory; and De Vries's The Origin of Species and Varieties by
Mutation. Simultaneously one may read with great profit Osborn's From
the Greeks to Darwin.
