W. Wynn Westcott, M.B. (H. K. Lewis. 12s. net.)— Tins is a technical book which cannot be treated in detail in these columns. We may indicate, however, some of the new subjects treated of in this, the fourteenth edition. We have chapters on

Acidi Lactici Bacillus," "Organic Arsenic Compounds," and "Radium." Nolen are given, or revised from an earlier form, on some sixty medicaments. The list of " Patent " medicines has been considerably increased.
