COTTA, BERNHARD VON (1808-1879), German geologist, was born in a forester's lodge near Eisenach, on the 24th of October 1808. He was educated at Freiberg and Heidelberg, and from 1842 to 1874 he held the professorship of geology in the Bergakademie of Freiberg. Botany at first attracted him, and he was one of the earliest to use the microscope in determining the structure of fossil plants. Later on he gave his attention to practical geology, to the study of ore-deposits, of rocks and metamorphism; and he was regarded as an excellent teacher. His Rocks classified and described: a Treatise on Lithology (translated by P. H. Lawrence, 1866) was the first comprehensive work on the subject issued in the English language, and it gave great impetus to the study of rocks in Britain. He died at Freiberg on the 14th of September 1879.
