This edition has been brought to date by the inclusion of many advances since the appearance of the previous edition. Time and space will not allow critical consideration that a work of this sort merits. If it were possible, however, to bring home to the attention of the young man just going out into practice the advice given in the introduction, much might be done to prevent him from "being blown about by every wind of doctrine." Sanity in the practice of medicine cannot be too strongly emphasized. While one might differ with the authors in many things, still, for a work of its sort, this is a good outline of therapeutics.
