Abstract
WE have received a copy of the fourth revised and enlarged edition of the booklet “pH Values”, which may be obtained free on application to British Drug Houses, Ltd., Graham Street, City Road, London, N.1. The booklet gives an elementary account of the subject, with particular reference to indicators. It is based entirely on the idea of a concentration of hydrogen ions, and the question arises whether the time has not come to take account of activities and salt effects more adequately than is the case. Further editions of the booklet should be revised so as to bring it more into line with modern practice.
