The inferior quadrants of thefundus, including both margins of the optic disc, exhibit a largenumber of orange-red choroidal capillaries. They are very numer-ous below the nerve-head, and suffuse the whole fundus near theperiphery with an orange-pink glow. Apparently there is but one macular area, situated above the discand on its nasal side. In the centre of this region is a small, white,round dot, surrounded by a brilliant blue-green reflex. There are,also, fine fibres radiating from the centre of the fovea. The papilla seems to be formed of a mass of coarse, white can be traced for about half its length only, the lower part being-obscur
