Very scarce. Lettres Philosophiques is an important publication that contributed several noteworthy observations to the sciences of biology and geology. Written as a series of four letters addressed to Johann Jacob Scheuchzer [q.v.], this volume touches upon many subjects of natural history. Included are theories on the formation of stalactites, the chronology of the earth, the generation of minerals and rocks, and the question of reproduction and development in living organisms. An additional tract titled "Memoire sur la theorie de la terre" considers numerous aspects of geological phenomena including the earth's destruction, which incorporates discussions of mechanical weathering, volcanism and earthquakes.
