Arthur Henninger, a French chemist of German birth, died October 4th, in the thirty-fifth year of his age. He studied and labored with Wurtz, and was distinguished for his experiments in the reduction of the polyatomic alcohols, and particularly of erythrite, by formic acid. One of the results of these experiments was the definition of a general method for the reduction of one alcohol to another of less atomicity. He was one of the editors of "Science et Nature."
Dr. Alfred Brehm, author of the "Thierleben," whose death was recently announced, was the son of a Thuringian ornithologist, and devoted his life to the study of all animal nature, but particularly of birds. He spent several years in the northeastern districts of Africa during his younger days, and later made scientific tours in distant lands, including Siberia, Turkistan, and Abyssinia. He was for some years Director of the Zoölogical Gardens at Hamburg.
Mr. R. A. C. Godwin-Austen, F. R. S., an English geological author of well-earned fame, died November 25th. His first geological paper was published in 1835. His favorite topic of study was the changes going on in the present day, especially along the coast.
