For many years I have been occupied, with my assistants and pupils, in an exhaustive study of the disorders of metabolism and nutrition. The result of this work has been a number of short essays published in various periodicals, and several longer monographs (Textbook on the Pathology of Metabolism, Berlin, 1893; Diabetes and Its Treatment, Berlin, 1st edition, 1893; 3rd edition, 1901 ; Chlorosis in Nothnagel's Handbook of Pathology and Therapy, Vienna, 1887; Obesity, in the same Handbook, Vienna, 1900.) The wishes of my friends and pupils have induced me to establish a medium for the publication in collected form of the results of our increasing experience in the pathology and therapy of the disorders of metabolism and nutrition. The first volume in this collection (On the Indications for Reduction Cures), and the second (On the Treatment of Acute Nephritis and Chronic Atrophic Kidney), have been already issued in German, the publisher being A. Hirschwald, Berlin. The other numbers should appear at intervals of four to six months. It has been arranged to have the collection contain not only dissertations from my pen, but also writings by my assistants and pupils, - of course under my control and responsibility. The monographs are to express, above all, the personal views and observations of the writers; or they will contain collective presentations upon important questions. Only such subjects will be chosen as are of importance and interest to every physician.

The following themes are under consideration for the immediate future but not positively decided upon:

The Treatment of Colica Mucosa (Enteritis Pseudomembranacea).

The Medicinal Treatment of Diabetes Mellitus.

Indications for and the Methods of Carrying out Feeding (mast) Cures.

The Technique of Reduction Cures.

The Significance of Aceton in Diabetes Mellitus

It is a source of satisfaction to me to announce that Messrs. E. B. Treat & Co., New York, have undertaken to publish the collection of these monographs in English. Particular care will be taken to have them appear hereafter as nearly simultaneously in New York and in Berlin as possible; and I hope that this American Edition will meet with the same approbation which I am happy to say has been accorded the German.
