The science of optics is the foundation stone of the proper understanding of the physiology of the eye. It is a difficult subject to teach because its physician students all have different backgrounds of training, at best elementary, in physics and mathematics. Most of the textbooks that are available assume a greater basic knowledge than is actually present, and for this reason most embryo ophthalmologists and optometrists find the subject of optics difficult. The author recognizes this handicap. He says in his preface, "The real title of this book should be 'An Introduction to Duke-Elder's Textbook Volume I.' " Keeping this plan in mind, he discusses the physics of light, geometric optics and the eye as an image-forming mechanism in terms that are straightforward, with a lucid and often entertaining style and with generous use of excellent figures and diagrams. The author is like Samuel Johnson's friend, Edwards, who said he
