The most important event in the department of psychiatry in Germany since my report in 1910 has been the Fourth International Congress for the Care of the Insane, which was held at the house of the Prussian Deputies in Berlin, from October 3rd till the 7th, 1910. The Congress was attended by about six hundred members. It compared favourably with its predecessors in the number and practical and scientific importance of the reports and in its general arrangements; it was evident that the interest of psychiatrists and of laymen in those congresses is on the increase. In addition to the meetings of the members, there was an important exhibition of models, plans and photographs of establishments and institutions for the insane, of sick-rooms and of machinery, of work done by patients in public and private institutions, and of scientific apparatus and books, which was visited with great interest, and which gave a very true idea of the progress in Germany in the care of the insane. The exhibition had been arranged by Dr. Alt, at Uchtspringe (Altmark). A no less true insight into German methods is given by a work on German Hospitals, which was edited by Dr. Bresler. A copy of this work was presented as a souvenir to each member of the Congress. It was edited with the assistance of the superintendents of the public and private asylums, and contains in an elegant volume of 666 pages the description of about seventy institutions for the insane, illustrated with numerous plans and photographs. This work has since been continued, and a second volume of 465 pages, with illustrations, has recently appeared. At the same time a similar work has been edited by Dr. Schloess, of Vienna, on Austrian asylums for the insane, copies of which (and of the second volume of the above-mentioned work) were also presented to the members of the Berlin Congress. So that it may be truly said that seldom have members returned from a congress with so abundant a supply of literature. A special number of my Weekly Journal of Psychiatry and Neurology was devoted to the members of the Congress, and contained about fifty portraits with short biographical sketches of the most distinguished alienists present. The more important papers are perhaps worthy of mention in this retrospect.
