L. Agassiz [Louis Agassiz] — Etudes Sur Les Glaciers

Neuchatel, Jent et Gassmann, 1840 . First edition. Leather. The scarce first edition of the text volume only of Louis Agassiz's pioneering work on glaciers and the Ice Age, which proved for the first time that glaciers move. In the original French. The text volume only of this scarce first edition. Both a text and an illustrated atlas volume were published, with the atlas volume not present here. A milestone work in the study of glaciation, focusing on the development, formation, movement and effect of glaciers.  Agassiz was innovative in his measurements of ice formations. His concept of an "Ice Age" during which glaciers advanced and retreated over a large part of the northern land-mass gave naturalists such as Darwin and Lyell a means of explaining the geographical distribution of species now separated by land or water barriers."
