Lectures on localization in diseases of the brain, delivered at the Faculté de médecine, Paris, 1875 . which the vascular ter-ritories are separated by dotted lines, will make the detailsclearer. The description of the striated arteries alone requires someexplanation. With this you will possess, in brief, all that isnecessary to a knowledge of the central arteries, whether theycome from the anterior or the posterior cerebral arteries. Emanating from the superior border of the Sylvian artery, the striated arteries enter the apertures of the anterior per-forated space, where they soon disappear from sight. But avery simple preparation renders it possible to follow them inthe first part of their intracerebral course. I solicit attentionto the following description, because that, in order to under- 72 DISEASES OF THE BRAIN. Stand some important facts, it is indispensable to know thetheory of common cerebral hemorrhage. That exposition consists in destroying successively thegray cortex of the island of Reil, the subjacent white sub-stance, the anterior wall, and finally the internal capsule.. Sphenoidal Horaoflat.Ventriclfi, cerebral Arteries Fig. 21.—Vertico-transverse section of the human brain, posterior to the tuber-cula mammillaria and anterior to the peduncles. Vascular territories indicated by-dotted lines. Thus the entire external surface of the lenticular ganglion islaid bare. If the preparation has been somewhat carefullymade, upon a well-injected brain—and the preparation iseasily made, because, in its anterior part at least, the lenticu-lar ganglion is as it were naturally detached from the internalcapsule—one can follow the first part of the distribution of CENTRAL ARTERIES. 73 the principal striated arteries. By this artifice it is seen thatthey spread like a fan at the surface of the gray ganglia. Butat a short distance from their origin they bury themselves inthe substance of the third segment, where they disappear. Now, it is upon the transverse
