Abstract
THE book under notice follows the lines of Prof. Henker's courses of lectures on spectacles; the German' edition from which the present translation by Mr. Kanthack is made was first published in 1921. Commencing from elementary principles, it gives an account of modern continental practice in spectacle optics, embodying the important work (in connexion with cataract lenses, telescopic spectacles, and other special aids to vision) of the Jena school under Prof. Moritz von Rohr. This has been mainly accomplished since the year 1908. While the War with its immense number of special cases of injuries to the eye un doubtedly gave a renewed stimulus to studies of this kind, many sufferers are still (as Prof. Cheshire points out in a foreword) ignorant of the aid which science can now give them. The present book should fill a great need if it gives information of this kind.

By Prof. Dr. Otto Henker. Translated by R. Kanthack. Pp. viii + 336. (Jena: School of Optics; London: J. W. Atha and Co., 1924.) 13s. 6d.
