He advocates symmetry in surgery if possible, but uni lateral operations in infancy seldom produce an asymmetrical effect. He regards the power of convergence an important clue as to the best surgical procedure. The writer considers this book the out standing classic in the study of squint. How ever, it is a mental challenge even to the ad vanced student of strabismus. Its primary importance is in the foundation that it lays in etiology on which the ophthalmologist can construct rational procedures. Lawrence T. Post.

evident reference to lens coating being down as "lens casting." The editor has carefully chosen from the world's ophthalmic literature those reports that have the greatest practical significance in diagnosis and therapy, but unfortunately modesty prevented any notice of his own publications. The articles selected are pre sented clearly, in adequate detail, and with all necessary illustrations. The clever juxta position of contributions on the same subject stresses a common or divergent viewpoint. The editorial comment, though apt, is de liberately minimal. A cover-to-cover perusal will give the reader a delightful experience, as well as an adequate perspective of the significant ad vances of the year in ophthalmology. James E. Lebensohn.

Edited by Derrick Vail, M.D., and Samuel J. Crowe, M.D. Chi cago, The Year Book Publishers, 1951. 427 pages, 138 illustrations, author and subject indexes. Price: $5.00. In its service to the organ of vision, oph thalmology has achieved many priorities. It was the first specialty to be recognized, the first to convene an international congress; and in this country, ophthalmology organized the first national society and established the first certifying board. Characteristically then, the Year Book series was inaugurated with the EENT section, and this volume marks a half century in its continuous publication. The year 1950 also closes a decade in the common era and, in commemoration thereof, the respective editors have prefaced each sec tion with a review of the progress made in the past years. AND THROAT.
Vail has judiciously placed the chief em phasis on the solid achievements of these years, though not neglecting those agents which suggest promising possibilities, such as hyaluronidase, strontium 90, cortisone, and ACTII. His account of optical advances contains one of the very few misprints, the

Wil son, who gave an account of his own exten sive observations and investigation of tra choma, a scourge which still affects 100 per cent of the village population. This lecture was followed by the reading of 38 papers on various topics, among them six papers in a symposium on myopia. The papers on trachoma, Koch-Weeks and gonococcic ophthalmia, schistosomiasis and leishmaniasis include experiences in the early years of chemotherapy. Sabri Kamel described a new operation for pterygium, which is of frequent occurrence in Egypt. He separates the pterygium from the cornea and sclera as far back as the caruncle and cauterizes the denuded area with carbolic acid. No sutures are used. Gamil Badir reported the occurrence of sympathetic ophthalmia in a young girl, eight days after the original accident. This is the shortest time interval between accident and
