In 1880 he was appointed special agent of the 10th census, and in 1882 was further appointed special agent in charge of the investigation of the precious-metal industries. His most important writings are “Geometrical Form of Volcanic Cones” (1885); “Notes on the Stratigraphy of California” (1885); “Cretaceous Metamorphic Rocks of California” (1886); “A Theorem of Maximum Dissipativity” (1886), which is a new fundamental law of mechanics, and one of its consequences is “A New Law of Thermo-Chemistry” (1886), which embraces the previously known laws of this science and makes an important addition to them. He has also written “Atomic-Weight Determinations; A Digest of the Investigations published since 1814” (Washington, 1880); “Geology of the Comstock Lode” (1882); “Statistics and Technology of the Precious Metals,” with S.
