E. J. Otogenic Paralysis of the Abducens.

Wm. Hardin Sears, M.D., F.A.C.S., Huntingdon, Pa. Paper, 8vo., 66 pages, 7 illustrations. Reprint from Trans. Amer. Laryngological, Rhinological and Otological So­ciety, 1925.

This was written as a candidate's thesis and contains a report of 26 cases, heretofore unpublished, including 2 of the writer's own; a tabulation of 172 cases, 145 previously recorded in the literature; and a bibliography of all references recorded to date. It makes especial mention of isolated palsy asso­ciated with irritation of the Gasserian ganglion. The illustrations bring out the anatomy of the parts, considered with reference to the possible routes of infection.

Abducens paralysis should always arrest the attention, and become a mat­ter of great interest to the oculist. The main facts regarding the 172 reported cases are presented in a table. The cases here published for the first time are reported in detail. This monograph with the bibliography that accompanies it, will be a valuable work of reference, for all who have to do with this serious complication of otogenous disease.

E. J. Tenth Annual Report of the Ophthal­

mic Section, 1922. Ministry of the Interior, Department of Public Health, Egypt. Paper, 48 pages. Published by the Government Press, Cairo, 1926.

This is a report, chiefly in tabular form, of ophthalmic conditions in Egypt, with special reference to Cairo. Probably the most interesting sections are those devoted to the Statistics of Blindness and Statistics of School Clinics. In 1917, 12 per 1000 of popula­tion were blind. The chief cause was acquired conjunctivitis, resulting in lesions of the eyeball. This is especially interesting in view of the statement that there is very little secondary in­fection following glaucoma operation,

one of the reasons for this latter fact being the more "resistent nature of the conjunctiva of the Egyptian." The Hospital Statistics show that there were almost twice as many patients treated in 1922 as in 1919, chiefly out­patients, as the number of hospitals had not increased. The number of times that the gonococcus was found was 11305, being more than all the rest together. The next most frequent organism was the Koch-Weeks bacil­lus, 5421. The trachoma statistics of school children are appalling! In only one school was there as low as 60%; the highest was 99.1% ; average 89.8%. There is a large amount of additional, valuable information contained in these tables, which would more than repay the investigator. The book may be ob­tained from the Government Publica­tion office, Ministry of Finance, Dawa-win P. O., Cairo, Egypt.

C. L. Legalized Optometry and the Memoirs

of Its Founder. Charles F. Prentice, M.E., Physical Eye Specialist, New York. Memorial Edition. Cloth, 12mo., 416 pages, 4 illustra­tions. Seattle, Casperin Fletcher Press, 1926.

The preface to the first part, on Legalized Optometry, signed by the publishers (having the same initials as the author) sets forth its intention "to narrate the history of optometry legis­lation in the United States of America." Further, it points out "the world at large is not informed concerning the reason for such legislation." Also "it is hoped that ophthalmologists will ac­cept this recital of the truth without prejudice and with full preparedness to make righteous allowance for the pro­vocation that justified the optician's acrimonious arguments." The edition "is limited to 200 copies for distribution among select subscribers."

The work of Donders, Helmholtz, Knapp and others fixed the attention of many physicians on the importance of ocular refrection thru its influence on human physiology and pathology. The medical profession in the United States was seeking by medical practice
