What Industry Owes to Chemical Science. By R. B. Filcher

and F. Butler-Jones. (Constable and Co. 3s. net.)—In this little book the authors cover a very wide field, showing briefly how every in- dustry, including agriculture, has benefited by the discoveries of the chemist. It is pleasantly written, and does not assume more than a very elementary knowledge of chemistry in the reader. Sir George Beilby, pointing the moral in his Introduction, says that the war has induced the workers in pure and in applied science to co-operate as they never did in the days of peace.
