BOOK NOTICES
much more precise diagnosis and at the same time a prognosis of considerable reliability as to the future evolution of the lesion. Occasionally it can be the cause of modification of the treatment by enabling the discovery of very min ute intracrystalline foreign bodies which would be invisible to other meth ods of examination. Its clinical value is, therefore, much greater where the in itial lesion is small. Chapter ten is con cerned with secondary cataracts and chapter eleven with the suspensory ap paratus of the lens. The authors conclude that while the biomicroscope furnishes important, precise, and useful clinical information, it does not create a new lens pathology. It gives old conditions a new appear ance, adds some details which had not been seen until its use, and permits ac curate prognostication in certain types of lens opacities. It must be constantly used in comparison with other methods of examination to avoid erroneous in terpretations. A complete bibliography is appended. The last part of the volume is made up of 36 plates in color, each plate con sisting of from four to seven figures. In addition to the biomicroscopic appear ance of the lesion each plate includes the appearance when viewed with oblique illumination and with the plain mirror. Phillips Thygeson.
Stereoskopischer Atlas der ausseren Erkrankungen des Auges, nach fabigen Photographien by Prof. K. Wessely in Munich. I l l Vol. Pic tures 21-30. Published by J. F. Bergmann, Munich. 1931. Price 12 marks. This third volume of the Wessely Stereoscopic Atlas in colors appeared after a considerable lapse of time in the same form as its predecessors. The conditions illustrated herein are : Senile Ectropion—Pemphigus of the Con junctiva—Epithelioma of the Con junctiva—Interstitial Keratitis—Chemosis and Exophthalmos in Orbital Periostitis—Subconjunctival Lipodermoid—Polykoria—Panophthalmitis— Hydrophthalmos—Sarcoma of the Choroid, broken through. On the back of each plate is a description of the case with short comments of a general or therapeutic nature in German, English, and French. With but few exceptions the pictures are good, particularly those of lower magnification. The color re production is very life-like, particularly the pronounced reds and blues, so that the student obtains a very clear idea of the process in vivo. In the teaching of small groups, these stereo photographs are becoming more and more valuable and these Wessely pictures promise to form the nucleus of an important ad junct to the teaching of ophthalmology. Harry Gradle.
