This special number of the American Journal of Insanity contains the exercises and papers delivered at the opening at the Phipps Psychiatric Clinic at the Johns Hopkins Hospital, Baltimore, Md. The contents of the entire volume should prove to be of the greatest interest to all students and lovers of psychiatry. The volume opens with a brief but fitting Introduction by Dr. Adolf Meyer, Director of the Clinic, a man to whom American psychiatry owes so much for the stimulus and inspiration which he has injected into others. This is followed by A Word of Appreciation by Henry D. Harland, President Trustees, The Johns Hopkins Hospital, some brief remarks on The Psychiatric Clinic and the Community by Stewart Paton, the heart-to-heart talk on Specialism in the General Hospital by Sir William Osler, and a short talk on The Purpose of the Psychiatric Clinic by Prof. Adolf Meyer. There then follow a series of fascinating and inspiring papers, as follows: The Sources and Direction of Psychophysical Energy, by William McDougall; Autistic Thinking by E. Bleuler; Personality and Psychosis by August Hoch; The Personal Factor in Association Reactions by Frederic Lyman Wells; A Study of the Neuropathic Inheritance by F. W. Mott; On the Etiology of Pellagra and its Relation to Psychiatry by O. Rossi; Psychic Disturbances Associated with Disorders of the Ductless Glands, by Harvey Cushing; Primitive Mechanisms of Individual Adjustment by Stewart Paton; Demenzprobleme by K. Heilbronner; The Inter-relation of the Biogenetic Psychoses by Ernest Jones; Prognostic Principles in the Biogenetic Psychoses, with Special Reference to the Katatonic Syndrome by George H. Kirby; Anatomical Borderline between the So-called Syphilitic and Metasyphilitic Disorders in the Brain and Spinal Cord by Charles B. Dunlap; and Mental Disorders and Cerebral Lesions Associated with Pernicious Anemia by Albert Moore Barrett. The number is concluded by the penetrating Closing Remarks of Prof. Adolf Meyer. The papers by Mott, Rossi, Cushing and Heilbronner are of the greatest interest. The discussions by McDougall and Bleuler are fascinating and uplifting. McDougall's paper is a masterpiece. Kirby, Jones and Hoch present us with the modern standpoints in the conception of the psychoses. Throughout the volume one sees the adoption of the broad biological standpoint in mental life. The adoption of the term "biogenetic psychoses" is indicative of the general trend. The adoption of this well-chosen phrase is, I venture to suggest, the product of Dr. Meyer. The reviewer regrets that the papers do not very well lend themselves for brief reviews. Furthermore, he would not attempt to briefly present the views which have been so lucidly and succinctly expressed by the individual writers. Prof. Meyer is to be commended for the very splendid program presented at the opening exercises of the Phipps Psychiatric Clinic.
