Book Description

Excerpt from A Sketch of the Natural History of the Diatomace These few words, by way of an introduction, have been deemed meces sary, so that the general reader, into whose hands these volumes may come, might understand that the geological survey of New Hampshire has been the first of our state surveys which has possessed a special microscopist, a person who has turned his attention particularly to the study of the application of that instrument, aided by other means of research, to the investigation of geology. It is true that similar investi gations have been made to some extent, by others as well as himself, for other surveys; but in no case hitherto have special collections been made systematically, and in such a manner that any very valuable results have been arrived at, for, in this branch of science as well as in others, a defi nite end should be had in view, and the specimens collected and the examinations made be for that end. It has remained for the state of New Hampshire to be the first to inaugurate a thorough microscopical survey of its geology and assistant branches of science, - paleontology.
