We believe this work is culturally important in its original archival form. While we strive to adequately clean and digitally enhance the original work, there are occasionally instances where imperfections such as blurred or missing pages, poor pictures or errant marks may have been introduced due to either the quality of the original work or the scanning process itself.

geologist mineralogist scientist
Delesse was born at Metz on the 3rd of February 1817.
At the age of twenty he entered the École Polytechnique, and subsequently passed through the Ecole des Mines.
In 1845 Delesse was appointed to the chair of mineralogy and geology at Besançon; in 1850 to the chair of geology at the Sorbonne in Paris; and in 1864 professor of agriculture at the École des Mines.
In 1878 he became inspector-general of mines. In early years as ingénieur des mines he investigated and described various new minerals; he proceeded afterwards to the study of rocks, devising new methods for their determination, and giving particular descriptions of melaphyre, arkose, porphyry, syenite, etc. The igneous rocks of the Vosges, and those of the Alps, Corsica, etc, and the subject of metamorphism occupied his attention. He also prepared in 1858 geological and hydrological maps of Paris—with reference to the underground waters, similar maps of the departments of the Seine and Seine-et-Marne, and an agronomic map of the Seine-et-Marne (1880), in which he showed the relation which exists beteween the physical and chemical characters of the soil and the geological structure.
His annual Revue des progrès de géologie, undertaken with the assistance (1860-1865) of Auguste Laugel and afterwards (1865-1878) of Albert de Lapparent, was carried on from 1860 to 1880. His separate publications were: Recherches sur l'origine des roches (Paris, 1865); Etude sur le métamorphisme des roches (1869); Lithologie des mers de France et des mers principales du globe (2 vols. and atlas, 1871).
