Dark blue half-chagrin, ornate ribbed spine, speckled edges (period binding). Extremely rare first edition of the major glaciological studies by Daniel Dollfus-Ausset (1797-1870), manufacturer and pioneer of glaciology. His work, fueled by his extensive research into the glaciers of the Alps and Pyrenees, as well as his expeditions across Europe in search of lost glaciers, was carried out in collaboration with such renowned scientists as Louis Agassiz, Pierre Jean Édouard Desor, Arnold Henri Guyot, Schimper, Hogard, Collomb, Karl Vogt and Dr. Kirschleger. The work appeared in 8 volumes of text, the first divided into 4 parts and the last into 3 parts, plus an atlas. This copy contains the first seven volumes of the work, organized as follows: Volume I is dedicated to authors who have studied high alpine regions and glaciers, as well as related issues. Volume II deals with the geology, meteorology and physics of the globe as applied to the high altitudes of the Alps. Volume III deals with erratic phenomena. Volume IV retraces the ascents. Volumes V and VI analyze active glaciers. Finally, Volume VII presents meteorological tables. This copy is complete with the atlas, comprising 40 double-page plates mounted on tabs, many in color, showing sections, plans and sketches, as well as 3 fine lithographed views: "Pavillon Dollfus-Ausset altde 2404. Glacier de l'Aar", "Station météorologique de Dollfus-Ausset (1er Août 1865 au 1er Septembre 1866) Col du St Théodule 333m Altde", and "Vue générale de la station Dollfus-Ausset au col du St Théodule". Several of the plates are signed by geologist Henri Hogard (1808-1880). Some rubbing and wear. Four covers damaged and missing. Some rare foxing to text volumes.
