Note 24 — Chapter I · Introductory: The Darwinism of Darwin, and of the Post-Darwinian Schools.

It is almost needless to say that besides the works mentioned in this chapter, many others have been added to the literature of Darwinism since Darwin's death. But as none of these profess to contain much that is original, I have not thought it necessary to consider any of them in this merely general review of the period in question. In subsequent chapters, however, allusions will be made to those among them which I deem of most importance.

[Since this note was written and printed the following works have been published to which it does not apply: Animal Life and Intelligence, by Professor Lloyd Morgan; The Colours of Animals, by Professor Poulton; and Materials for the Study of Variation, by Mr. Bateson. All these works are of high value and importance. Special reference should also be made to Professor Weismann's Essays.]
