Abstract
A SOUND statement of the optical principles involved in ophthalmology, which nevertheless does not require a knowledge of higher mathematics, and which is confined within reasonable limits, has no doubt been long sought by students of this special branch of surgery, and in “Elementary Ophthalmic Optics,” now under notice, they will find a trustworthy exposition of the laws affecting the refraction of the eye. The book is well printed and the diagrams are large and clear; it seems a pity, perhaps, that the author was not bold enough to depart from the conventional letters used in optical formulae, which, such as f,f1,f′1,f′2, become liable to confusion, though it is difficult to suggest better symbols offhand.

By J. H. Parsons. Pp. 162. (London: J. and A. Churchill, 1901.) Price 6s. 6d.
