It gives me satisfaction that the first edition of my Lectures on Dietetics (delivered at the New York Postgraduate Medical School and Hospital) has been exhausted, and a new issue required. The present volume has been doubled in size, so that it is almost a new book. Nine new chapters have been added, namely:

V. The Care of Digestion; VI. The Care of Digestion for the Soldier; IX. The Dietetic Management and the Allen Treatment of Diabetes Mellitus; X. The Dietetic Management of Gout; XI. The Diet in Diseases of the Kidneys; XIII. The Diet in Operative Cases; XIV. Subcutaneous and Rectal Alimentations; XVI. Indications for Artificial Nutrition; XVII. Preparation of Food for Invalids (The Diet Kitchen).

The reader's pardon is asked for some repetitions in the text, due to the fact that some of the incorporated lectures have been delivered at different periods of time and not as a continuous course. The points mentioned are, however, usually of importance and will by repetition make a more lasting impression and thus perhaps be of greater use.

It is hoped that the present book, like its predecessor, will contribute toward the spread of knowledge of Dietetics in this Country.
