Louis MANGIN, former director of the Museum national d’Histoire naturelle in Paris, died at Orly on January 27 last. Born at Paris on September 8, 1852, Mangin was of Lorraine origin. He first studied botany under Le Monnier at Nancy and then with van Tieghem at Paris. He became professor of natural sciences at the Lycee of Nancy when twenty-one years of age, and at Louis-le-Grand when twenty-nine. His first researches showed the influence of his teachers and were concerned with plant anatomy and physiology; his thesis for his doctorate was on the adventitious roots of Monocotyledons. In collaboration with Gaston Bonnier he undertook research on respiration, transpiration and carbon assimilation, with results which are of interest in the historical developments of these subjects. This was followed by investigations on the physiology of Basidiomycetes, pioneer work which has not been much added to in the fifty years which have since elapsed.
