    anterior ciliary, long and short posterior ciliary, muscular, palpebral, centralis retina, frontal and nasal (terminal branches). Infra-orbital (from int. maxillary of ext. carotid) sends branches to inf. rectus and inf. oblique muscles, and to lachry- mal gland. Anterior cerebral sends nutrient capillaries to optic nerve. In eyeball itself are two systems : (1) the retinal, derived from the centralis retina: vessels, which sup- plies retina and optic nerve ; and (2) the choroidal or ciliary, from ciliary vessels, which supplies uveal tract, sclerotic, margin of cornea and part of ocular conjunctiva. The short ciliary, arising from ophthalmic or one of its branches, are 4 to 6 small twigs which divide into about 20 and perforate sclerotic around optic nerve. The long ciliary having same origin as short, are two branches which perforate sclerotic a little further for- ward, one on medial and one on lateral side. The anterior ciliary, arising from muscular branches, pass through tendons of muscles and perforate sclerotic near corneal margin. The only connection between the two above systems is by small twigs around optic nerve entrance (p. 7). Anastomosis : with deep temporal and transverse facial by malar branches, and middle meningeal by posterior branch from lachrymal. With anterior temporal and angular by supra-orbital.
