Toxic Eye Hazards
BOOK REVIEWS this article were obtained by using radon (not radium-D) applicators. The experiments and clinical results from the use of a Swanberg radium-D applicator at the University of Illinois have been reported by Dr. Fred M. Wilson at the 1949 meeting of the Association for Research in Ophthalmology. Dr. Wilson found important differences between the effects of radium D and radon, the former showing about 40-percent effective beta output and less penetrating power. These differences are important in the practical aspects of treatment; for example, duration of treatment and ability to eliminate corneal vascularization and other pathologic processes situated more deeply in the lids, cornea, and sciera.

Editor, American Journal of Ophthalmology: In the May, 1949, issue of the JOURNAL, page 702, Lieut. V. O. Eareckson brings forward Wright's staining method as "a rapid staining technique for the demonstration of trachoma inclusions." Forty years ago I brought forward the same method for the same purpose—"A rapid method of staining the trachoma bodies of Halberstaedter and Prowazek," Ophthalmic Record, October, 1909. Probably the reason it did not come into general use was that it requires more careful attention to detail than does the Giemsa method. (Signed) F. H. Verhoeff, Boston, Massachusetts.

Otolaryngology. Publication No. 494. New York, The National Society for the Prevention of Blindness, 1949. 34 pages, 10 illustrations, bibliography. Price, $1.00. The preparation of this manual and the extensive work that went into its background excites profound admiration for all who had a part in its formation and assisted in its publication. It is a factual, practical, and inexpensive masterpiece of great use to industry and ophthalmologists working with industrial eye problems. Chapter I has to do with standards and tests for eye-protection equipment. It describes, as an example, a well-organized eyeprotection program. Part II of the first chapter gives tables of toxic compounds and the ocular signs and symptoms they produced. Chapter III contains an excellent description of standard emergency and first-aid procedures in chemical eye injuries, based upon the completely satisfactory results obtained from practical experience. The manual should be read and studied by every ophthalmologist, whether interested in industrial ophthalmology or not, and by every physician employed by industry. Derrick Vail. UEBER

FEHLER
By Georg Wilhelm Keyser, M.D. Oslo, Norway, A. W. . Brjrfgger Press, 1943. Paper covers. 174 pages, bibliography, 2 colored plates. Price, not listed. The problems of color vision have excited a marked recrudescence of interest in the past decade. Keyser, as a practicing ophthalmologist, is primarily concerned with the color capacity requisite for the performance of various tasks. The introductory chapters review both critically and comprehensively the contributions to our knowledge of color deficiency, from the original discovery by Dalton of his own color blindness in 1794 to the present.
