Also included are computations and tables on the atomic weight of elements and compounds; a budget proposal for the United States Geological Survey; memorabilia; a photograph of Clarke; and an annotated copy of Clarke's "The Constants of Nature, Part I: A Table of Specific Gravity for Solids and Liquids," Smithsonian Miscellaneous Collections, Number 659, 1888. Some materials are in French and German.
Frank Wigglesworth Clarke (1847-1931) was a geological chemist. Clarke taught chemistry and physics at Howard University in Washington, D.C., 1873-1874, and at the University of Cincinnati, 1874-1883. While teaching at Howard University and the University of Cincinnati, Clarke collaborated with the Smithsonian Institution on atomic weight research. In 1883, Clarke joined the United States Geological Survey and served as Chief Chemist until 1925. Clarke was also Honorary Curator in the Division of Mineralogy and Petrology, Department of Geology, United States National Museum, 1883-1931, where he organized the Museum's mineral and gem collection.
