WHITE, Charles Abiathar, geologist, born in North Dighton, Massachusetts, 26 January, 1826. He removed to Iowa in 1839, and was graduated at Rush medical college in 1863. Three years later he became state geologist of Iowa, which appointment he held until 1870, and in 1867-'73 he was professor el natural history in the Iowa state university. In 1873 he was called to the same chair in Bowdoin, but he resigned two years later, and during 1874 was geologist and palaeontologist to the United States geographical and geological surveys west of the 100th meridian under Lieutenant George M. Wheeler. He then passed to the service of the survey under Major John W. Powell in 1875, and in 1876 to that under Ferdinand V. Hayden, with whom he remained until 1879. Dr. White had charge of the palaeontological collections in the United States national museum in 1879-'82, and in 1881 was detailed to act as chief of the artesian wells commission upon the Great Plains under the auspices of the United States agricultural department. Since 1882 he has been connected with the United States geological survey, first as geologist, and since 1883 as palaeontologist in charge of the division of mesozoic invertebrates. His knowledge of his specialty has gained for him a reputation as an authority that is unequalled in certain branches of fossil life. The degree of A. M. was conferred on him by Iowa college, and he holds an honorary curatorship in the United States national muse-urn. He is a member of scientific societies, was president of the Biological society of Washington in 1883-'4, and was elected a vice-president of the American association for the advancement of science in 1888. His writings include nearly 200 papers, of which the most important are included in the reports of the various surveys with which he has been connected, also a work on the cretaceous invertebrates of Brazil, which were collected by the Imperial geological commission, under the direction of the late Charles F. Hartt, to form vol. vii. of the "Archives of the Brazilian National Museum" (Rio de Janeiro, 1887).
