Voluminous collection of correspondence from noted French geologist and paleontologist Charles Depéret, dean for 33 years of the Faculté des Sciences at Lyon and author of nearly 300 works on geology, paleontology and archeology, including the classic monograph “Les terrains tertiaries de la Bresse” (1893; written with F. Delafond), and Les transformations du monde animal (1907), a work that “clearly and accurately explains the great problems of paleontology” (Dictionary of Scientific Biography). In 1892, based on his stratigraphic research, Depéret introduced the Burdiglian Stage of the Lower Miocene, spanning the time between 20.43 – 15.97 million years ago. Depéret also known for “Depéret’s Rule” of progressive evolutionary specialization, stating that when a population group starts to specialize it can only specialize further and never return to a more generalized state.
All the letters in this volume were written to Depéret’s sister, Louise, and her husband, Dr. Félix Salètes, physician and author of Conférences pratiques sur les premiers soins à donner aux blesses (1899); it was their son, Paul Louis Jacques Salètes, who had the letters bound in the present volume under the title “Correspondance de l’Oncle Charles.” The well-organized letters include references to Depéret’s work and his travels in Europe and America for research or to attend scientific conferences.Book Id: 44437
