(Born: Southport, Connecticut, U.S.A., 29 July 1844; Died: Princeton, New Jersey, U.S.A., 1 April 1917) American mining engineer & chemist.

Cornwall was a graduate of Columbia College in 1864, and its School of Mines in 1867 as a mining engineer. From 1865 till 1873, he was an assistant in the School of Mines, with the exception of two years spent in study at the Freiburg Bergakademie. In 1873 he was elected to the chair of analytical chemistry and mineralogy in the school of science of the College of New Jersey. In 1865 he was appointed superintendent of the Continental Zinc and Lead company, of New York. During 1870-'1 he filled a similar office in the Geñeral Silver-Mining Company, and spent fifteen months while in their employ examining the Batopilas mines, in Mexico. Cornwall has published numerous scientific papers, and has paid special attention to water-analysis.

Very scarce. Cornwall's volume includes the general range of topics usually discussed under the general description of blowpipe analysis. Characterized by the excellent writing that gives full and complete descriptions, the directions for the techniques of manipulation and result interpretation are presented in such a manner that even a beginner could make use of the book.
