Extract¶

Chamberlin read his paper before the Society of Western Naturalists on October 25, 1889, and it was published in Science on February 7, 1890. The revised version was published in the Journal of Geology in 1897. The chief difference was that the 1897 text was 'freely altered and abbreviated so as to limit it to aspects related to geological study.'
