The third branch of the anterior cerebral arteryis sent to the quadrilateral lobule, which may be subject tolesions on its own account, as I have just now given you anexample. 58 DISEASES OF THE BRAIN. IV. The posterior cerebral artery (Figs. 12, 16, and 17)often suffers alterations by embolismus and thrombus. Ischsemic softenings of the posterior lobes are much morecommon than with the anterior lobes. The territory of this artery is divided into three secondary e^I^^f*^^.

The first of these goes to the gyrus angularis; thesecond to the inferior part of the sphenoidal lobe, embracingthe inferior sphenoidal convolution and the fusiform lobule ;the third goes to the lingual lobule, to the cuneus, and theoccipital lobe proper.
