But there is still another strikingdifference between these infantile and adult apoplexies. In the adult themajority of hemorrhages occur in the vicinity of the internal capsule. In thechild they occur in or near the cortex. Mendel has shown that the greatestpressure is exerted in the branches of the middle cerebral artery, and thatany increase of pressure would naturally cause a rupture in one of would have to seek some other explanation for the frequent occurrenceof cortical and meningeal hemorrhages, and perhaps they will be sufficientlyaccounted for by the more delicate structure of these vessels in children.
