ALFRED EDWIN HOWARD TUTTON, who died on July 14, was born on August 22, 1864, at Cheadle Moseley, now the Edgeley district of the borough of Stockport. He attended science classes at the Stockport Mechanics Institute and also the evening courses in chemistry of Prof. Roscoe at Owens College, Manchester. In 1883 he went to the Normal School of Science (later the Royal College of Science) and Royal School of Mines, South Kensington, with an exhibition, which he took in preference to a scholarship which he had gained for Owens College. During his period as a student, Huxley was professor of biology, Frankland of chemistry, Guthrie of physics, Judd of geology and Lockyer of astronomy, and a fellow-student was H. G. Wells. Tutton was a brilliant student and gained several scholarships and prizes. In the meantime, Thorpe had succeeded Frankland as professor of chemistry, and under his direction Tutton began the research on the lower oxides of phosphorus in which the new oxide P2O4 was discovered and the lower oxide P4O6 was first prepared in a state of purity and definitely characterized in its properties. This work was published in 1890 and 1891. In 1889, Tutton had been appointed to the post of demonstrator in chemistry and lecturer in chemical analysis at the College. During this period, he also assisted Thorpe and Rücker in the magnetic surveys of Scotland and England.
