BOOK NOTICES

is a comprehensive text on the influences regulating the anomalies in development and the clinical appearance of the defects. There are excellent illustrations including the anomalies of the interior of the eye. The congenital lenticular changes are well shown. The general pathological and therapeutic considerations of the diseased eye are taken up in Section Xlunder five categories, metabolic disturbances, circulatory changes, degenerations, disturbances of growth, and inflammations. Section XII is devoted to diseases of the conjunctiva, cornea, and sclera. There are 311 pages dealing with conjunctival afflictions. The diseases of the cornea are described in detail and the illustrations are clearly and accurately reproduced. There are 233 pages of excellent material. The final chapter covers the diseases of the sclera. This volume will be an integral part of the clinical ophthalmologist's library. The tremendous amount of material presented, the clarity of the text, and the comprehensiveness of the bibliography and index make this work monumental in its field. The early appearance of volumes III and IV is desired. William M. James. A TEXTBOOK OF EYE, EAR, NOSE AND THROAT NURSING. By Abby-Helen Denison, R.N., completely revised by Lyyli Eklund, R.N. 368 pages. The Macmillan Company, 1937. The book has been prepared for the instruction of nurses. The simplicity of the presentation of the anatomy, physiology, and pathology of the eye, ear, nose, and throat makes it valuable as an outline for teaching. The technique of nursing procedure in relation to diseases of the eye, ear, nose, and throat is clearly outlined and freely illustrated. This work will be of particular value to anyone en-

gaged in teaching nurses or undergraduate medical students. William M. James. STRUCTURAL VARIATIONS OF THE HUMAN IRIS AND THEIR HEREDITY. By Viggo Eskelund. Paper covered, 242 pages, illustrated with 54 plates of photographs in monochrome. London, H. K. Lewis & Co., Ltd., 1938. The observations reported in the present work were carried out in the Anatornico-Pathological Institute of the University of Copenhagen. The first problem consisted of examinations of the normal limits of the iris variations and their relative frequency and combinations. The next problem was the investigation of the existence of these variations where related persons were concerned, and this especially with a veiw to the possible advantageous application of iris examinations in cases of alleged paternity. Variations in the appearance of the iris show in its"frontal boundary" or anterior border layer. Greatly enlarged photographs were used as the basis of an all-round estimation of the structural variations of the iris. In this photography, a Zeiss-Tessar 4.5 with a focal length of 15 em. was fitted onto a Graflex camera. Very fine-grained silver-eosine plates were used allowing enlargements of 15 times. For lighting the ms, a small flash-light was used, with a tin-foil reflector placed about 0.75 meter from the eye. The duration of the flash was about Ij50 sec., which is too brief an interval for the contraction of the pupil to show in the photograph. The principal factors of variation in these observations on the iris were the number of concentric contraction furrows, the degree of transparency or opacity in the pupillary or central zone and that in the ciliary or peripheral zone, the relation of
