PROF. ALFRED SENIER, who died on June 29 at Galway, was born at Burnley on January 24, 1853. His parents, about two years after his birth, emigrated to Wisconsin, where he deceived his early education. In due course he attended the Universities of Wisconsin and Michigan, and graduated as doctor of medicine of the latter in 1873. But his interest lay principally in the subject of chemistry, and, returning to England, he filled, under Prof. Attfield's direction, the posts of assistant and demonstrator in chemistry to the Pharmaceutical Society in London from 1874 to 1882, and, afterwards, for about three years, that of lecturer in chemistry in St. John's College, Battersea, of which the Rev. Canon Daniel was at that time principal. He then became a research student with Prof. von Hoffmann, and after a period of three years received the degree of Ph.D. from the University of Berlin. His inaugural dissertation, “Ueber Cyanursaure, ihre Isomeren und Derivate,” on receiving this degree, was published. In 1890 he became locum tenens for Prof. Maxwell Simpson in Cork, and in 1891 he was appointed professor of chemistry and lecturer in medical jurisprudence in Queen's College, now University College, Galway.
