This well known standard textbook has been revised and brought down to date by R. J. E. Scott. It is intended to serve as a compendium of information regarding both official and nonofficial drugs and preparations. Following introductory chapters of general definitions and discussion, drugs are taken up alphabetically with an exposition of their action and uses. This is followed by a brief chapter on pharmacy and prescription writing from the prescriber's standpoint. An alphabetical list of symptoms and diseases, in which their modification and treatment by medicine is concisely noted, occupies about a third of the volume, and an appendix on prescription Latin, antinarcotic regulations and prohibition regulations conclude the book.
