Unusual opportunities are afforded by war injuries for the observation of disturbances of the visual functions in their relation to more or less circumscribed lesions of the brain, and several important contributions to this subject have been published in foreign journals since the beginning of the world war. In 1916, Holmes and Lister 1 reported their observations on a large series of cases of this type and deduced the following conclusions : 1. The upper and lower halves of each retina are

The center for macular vision lies in the posterior part of the visual area, probably on the margins and lateral surfaces of each occipital pole. The macula has not a bilateral representation. 3. The center for vision subserved by the periphery of the retina is situated in the anterior part of the visual area, and serial concentric zones of the retina from the macula to the periphery are represented in this order, from behind forward in the visual cortex.
