[Illustration: Henry E. Roscoe _Photo. E.H. Mills._ _Walter L. Colls. Sc._] The Right Honourable Sir Henry Enfield Roscoe P.C., D.C.L., F.R.S. A BIOGRAPHICAL SKETCH BY SIR EDWARD THORPE, C.B., F.R.S. LONGMANS, GREEN AND CO. 39 PATERNOSTER ROW, LONDON FOURTH AVENUE & 30TH STREET, NEW YORK BOMBAY, CALCUTTA, AND MADRAS 1916 [_All rights reserved_] ADVERTISEMENT This sketch of the life and activities of Sir Henry Enfield Roscoe is based, to a large extent, upon an obituary notice prepared at the request of the Councils of the Royal and Chemical Societies, of which its subject was a distinguished member, with a view to publication in their respective _Proceedings_ and _Transactions_. In its present more extended form it is offered to a wider public as the record of “a life in civic action worn,” and as a slight tribute from a grateful pupil, an attached co-worker, and a lifelong friend to the memory of a strenuous high-minded man, of large aims and generous impulses, who spent his abilities and energies unstintingly in promoting the welfare of science and the good of his kind.
