BOOK NOTICES

The unique value of this book appears, when we know that the author became blind at the age of eleven years ; and continued his studies to a Master's Degree, from the Univer sity of Oregon.

By Dario Sabbadini. Extracted from the Pro ceedings of the Italian Ophthalmo logical Society, 1931. Paper covers, 204 pages. Price not stated. 1932, L'Universale Tipografia Poliglotta, Rome. This thesis was prepared by special request for the twenty-first meeting of the Italian Ophthalmological Associa tion in 1928. It contains an elaborate historical review of retinal detachment and its treatment, and a particularly careful account of recent methods, in cluding those of Gonin, Guist, Lindner, Arruga, and Sourdille. The author thinks that cures obtained by methods antedating that of Gonin were probably based upon closure, either spontaneous or accidentally in duced, of retinal tears which had not been previously recognized. The mono graph is accompanied by an extensive bibliography as far as the latter part of the year 1931. W . H. Crisp. Bulletin, Ophthalmological Society of Egypt, Vol. XXV, 1932. Paper Octavo, 255 pages. Illustrated by 23 plates. Cairo, Msr. Press, 1932. This is the largest volume of Transac tions issued by this Society, and it must be recognized as an important contribu tion to the current world literature of ophthalmology. It tells of the 30th an nual meeting of the Society, held in the Memorial Ophthalmic Laboratory, Giza, March 25, 1932. It has both scien tific and historic value. The Presiden tial Address, by Dr. M. Khalil goes into the history of the Society, the welfare of the blind in Egypt and the connec tion of trachoma with blindness. There is also a commemoration of "MacCallan's Twenty Years Service in Egypt," (1903-1923). There are photographs of Dr. MacCallan, and the bronze memo rial bust of him, given by his pupils and
colleagues, and unveiled in March, 1931. There is also his message of thanks on that occasion, pointing out that "asso ciation with ophthalmic work in Egypt has been the direct cause of my obtain ing honorary hospital appointments in London." There is also an account of the visit of Dr. M. Azmy El Kattan to America, to attend the New York Con gress for the Welfare of the Blind, in April, 1931. On the scientific side, there are not able papers on Tattooing of the cornea with platinum chloride; Treatment of anterior staphyloma with galvanociliarotomy; Operations of Gonin and Sourdille for detachment of the retina ; and over twenty other papers on prac tical subjects, including treatment of trachoma with intramuscular and intra venous injections. There is a paper on Slitlamp study of the corneal vessels in Egyptian trachoma, by Dr. Row land P. Wilson, Director of the Giza Laboratory. This article is illustrated by two plates in colors, showing the ves sels in the limbus in normal and trachomatous eyes. Wilson finds t h a t : "Pannus, in one form or another, is in variably present in the disease, and is therefore not a complication but a part of it." There is also a paper on "Pitui tary tumors and others in relation to the sella turcica," which should receive attention, for its x-ray pictures of the sella and field charts.
