DR. ARTHUR WILLIAM CROSSLEY, who died at his residence, Thorngrove, Alderley Edge, Cheshire, on Saturday, Mar. 5, at the relatively early age of fifty-eight years, was the son of the late Richard Crossley and was born at Accrington on Feb. 25, 1869. His early education was obtained at Mill Hill School, from whence he proceeded to the Owens College, Manchester, then part of the federated Victoria University, where he graduated in the honours school in 1890. It is evident that thus early in his career his tastes inclined towards the organic side of chemistry because, after graduating, he went to Wurzburg to work under Emil Fischer, then well on the way towards the zenith of his fame, and from there published his first paper, a short note on the optical behaviour of dulcitol, in 1892. He graduated Ph.D. at Wiirzburg in 1892 and then followed Fischer to Berlin, from which University he published his second paper, on the oxidation of mucic acid, in 1894.
