This work is an inaugural dissertation describing the course of the primary optic neuron in twenty-four rabbits and fourteen cats. Various circumscribed lesions were made in the retina of the animals, and after they had lived eighteen days the brains, including the optic nerves, were then prepared by the Marchi technic with complete serial sections and the degenerated fibers, both on the crossed and on the uncrossed sides, were followed to the primary optic centers. The technic is described in detail and the protocol of the experiments, with careful description of the sections and illustrative figures of each are given. The literature is reviewed and conclusions are drawn and discussed.

Dr. Overbosch's experiments are valuable and his observations important. They show that there is a definite plan of localization in the projection of the fibers from the different quadrants of the retina through the optic nerve, chiasma and tract into
