The author believes that with photographs of the fundus oculi, a better conception of changes in the blood vessels, optic nerve, retinal and choroidal lesions is possible, and that the illustration is rather enhanced by absence of color. This atlas, the first in English, is based on 4,000 photographs made with the Nordenson camera of Zeiss. The pictures are grouped to display the normal fundus with its physiologic variations, the lesions of the retina, choroid and optic nerve, and in terms of general subjects like arteriosclerosis, syphilitic disease, diabetes and others. In the foreword, the author speaks of the necessity of first familiarizing oneself with the characteristics of photographs of the fundus ; thus only can the various color densities be appreciated. The refractive error must be remembered in the case of the transitions of the fundus. Changes in the nervehead and in the course of the vessels are then described.
