describing operations in which they had departed from the Gonin technic. Weve, of Utrecht, described the method of us­ing diathermy in the treatment of retinal detachment. One cannot glance at these papers without realizing that the Gonin operation has awakened a great interest in the subject, and that famous men of large experience are try­ing in different directions, to find meas­ures that will greatly improve the prog­nosis for such detachments.

I t is impossible to mention all the im­portant subjects that claimed the at­tention of the meeting and brought out general discussion. J. Igersheimer re­ported on experimental therapy for tetany cataract ; and H. K. Mueller on experimental production of cataract. There was a paper by E. Werdenberg, of Davos, on the antagonisms and parallelisms between ocular and thor­acic tuberculosis, with three other papers on tuberculosis, that brought out a broad discussion. Glaucoma and related subjects of course came in for discussion, by several papers read at two of the sessions.

This Society has in many ways re­covered from the adverse influence of the world war. I t shows a broader in­terest and a greater readiness to receive new suggestions and take up investiga­tions on new lines than it had previ­ously manifested.

Radiologie Maxims. By Harold Swan-berg, with a foreword by Henry Schmidt. 126 pages. Paper covers, price $1.50. Radiological Review Publishing Company, Quincy, Il­linois, 1932.

This little booklet may be said to achieve originality in its method of presentation, but it is hardly to be recommended as a work of instruction or reference. As far as the author's per­sonal share in it is concerned, it con­sists of a number of disjointed para­graphs under various heads, and be­tween groups of such paragraphs are interpolated quotations from miscel­laneous writers on cancer, radiotherapy, and roentgenotherapy. Most of the au­

thor's short paragraphs, and also most of the quotations, are devoted to stat­ing, with much repetition, the purposes to which radiotherapy or roentgeno­therapy may be applied, and little is said about technique of diagnosis or therapy. An index is included.

Augenheilkunde des praktischen Arz­tes, ein Leitfaden für Aerzte und Studierende (Ophthalmology of the practical physician, an outline for physicians and students). By Dr. K. Vogelsang, Privatdozent at the University of Bonn. 121 pages, with 22 illustrations. Paper covers, price 4 marks. Urban und Schwarz-enberg, Berlin and Vienna. 1933.

This insignificant little volume is am­plified from some articles published by the author in Medizinische Klinik. It touches very briefly on one eye disorder after another ; so briefly, that one finds difficulty in understanding what practi­cal purpose the volume might serve, unless perhaps as a short key or re­minder of things learned during under­graduate study. Among other doubtful utterances, one is surprised to find the statement that it is absolutely neces­sary to dissect out the sac of a chala-zion as relapse will otherwise occur; the author being evidently unfamiliar with the technique of curettement. The extreme importance of differential diag­nosis between iritis and glaucoma is mentioned and the subject is then dis­missed in a few inadequate lines. The author allows his cataract patients to get up on the second or third day.
