1858 Natural Selection: the original paper by Darwin and Wallace
1909 Charles Darwin: On the Hundreth Anniversary of his birth

On July 1, 1858, before the Linnean Society, the theory of Natural Selection made its first public appearance in the form of a joint paper by Charles Darwin and Alfred Russel Wallace. This rare article is reproduced in this electronic reprint. The article contains an introduction, by Sir Charles Lyell and Sir John Hooker, a two part article by Darwin and an article by Wallace. As stated in its introduction it includes:

1. Extracts from a MS. work on Species, by Mr. Darwin, ... . The first Part is devoted to "The Variation of Organic Beings under Domestication and in their Natural State;" and the second chapter of that Part, from which we propose to read to the Society the extracts referred to, is headed, "On the Variation of Organic Beings in a state of Nature; on the Natural Means of Selection; on the Comparison of Domestic Races and true Species."

2. An abstract of a private letter addressed to Professor Asa Gray ..., by Mr. Darwin, in which he repeats his views.

3. An Essay by Mr. Wallace, entitled "On the Tendency of Varieties to depart indefinitely from the Original Type."

To provide additional background, we have added a survey article, given by August Weismann as an address delivered at the University of Freiburg on the occasion of the Centenary of Darwin, which we have reprinted from "The Contemporary Review" July, 1909.
