HERBERT, EDMOND (1812-189o), French geologist, was born at \'illef argau, Yonne, on June 12, 1812. He was educated at the College de Meaux, Auxerre, and at the Ecole Normale in Paris. After holding various appointments he was appointed in 1857 professor of geology at the Sorbonne. To him we owe the first definite arrangement of the Chalk into palaeontological zones (see Table in Geol. Mag., 1869, p. 200). During his later years he was regarded as the leading geologist in France. He was a member of the Institute, and was three times president of the Geological Society of France in the course of his life. He died in Paris on April 4, 189o.
