In view of the current interest in nervous influences on intraocular structures, it was thought timely to re-examine the anatomy and topographical interrelations of the posterior ciliary nerves of several species used in recent neurophysiological investigations. The anatomy of the motor, sensory, and sympathetic nerves supplying the globe has been described previously for the cat and rabbit,1,2 but certain points of disagreement remain unresolved. Comparison with the corresponding nerves of monkeys and man has not been pursued. In the present study, the content of the orbits was carefully dissected after the nerves had been stained by a modification of Christensen's silver method. This technique facilitated the demonstration of fine nervous connections and permitted photographic recording of anatomical detail.

Method  Both eyes of 30 cats, 10 rabbits, and 20 monkeys (Macaca mulatta) were dissected. The complete orbital content together with intracranial portions of the third, fourth, fifth, and sixth nerves
