The gray matter is the continuation of the same matter of the cordand medulla. Three cranial nerves are in connection with the mid-brain,viz. third, fourth and fifth nerves. The nuclei of the third and fourthform a continuous column of nerve-cells situated in the gray mattersurrounding the aqueduct of Sylvius. A section through the posterior THE CENTRAL NERVOUS SYSTEM 23 quadrigeminal bodies shows the origin of the fourth nerves and throughthe anterior bodies the origin of the third nerves (Fig. 19).
