PREFACE TO THE SECOND EDITION.

IN preparing this edition, the entire book has been subjected to a thorough revision. Many portions have been entirely rewritten, and a number of new subjects have been introduced.

Among the new sections may be mentioned Bubonic Plague, Gastroptosis, Gastric Analysis, and Reichmann's Disease. The subject of Malaria has been entirely rewritten. The section on Diseases of the Digestive System also has been largely rewritten, especially the following subjects Gastritis; Dilatation of the Stomach; Gastric Atony; Ulcer of the Stomach; Gastric Neuroses; Enteritis; Colitis, etc.

Throughout the book, wherever it seemed necessary, new matter has been added, to bring the subject down to date.
