MORSE, Harmon Northrup, chemist, born in Cambridge, Vermont, 15 October, 1848. He was graduated at Amherst in 1873, and then studied in Germany, where in 1875 he received the degree of Ph. D. from the University of Gottingen. On his return to the United States he became assistant in chemistry at Amherst, and remained there until 1876, when he became associate professor of chemistry and sub-director of the chemical laboratory at Johns Hopkins. Dr. Morse has been exceedingly active as an original investigator since he settled in Baltimore. Not only has his attention been directed to various researches in organic chemistry, but it also includes descriptions of original methods of determination, and the devising of improved forms of apparatus. His papers number about twenty-five, and have appeared in the "American Chemical Journal," to which he has been an editorial contributor from almost its earliest issue, and also in the "Proceedings of the German Chemical Society," of which he is a member.
