Heubner divides the entire arterial supply of the encephalon into two systems—viz., a basal and a cortical arterial system. Duret’s primary division is essentialy the same, except that he uses the term 1 central’ to designate what Huebner speaks of as 1 basal/ Fig. 1.

The Basal Arterial System is represented by the circle of Willis and the principal trunks of the cerebral arteries for a distance of ^-1 from this circle. From these trunks numerous small or very small branches pass off at, or nearly at, a right angle and sink almost immediately into one or other of the important ganglia near the base of the brain. These vessels are true terminal or ‘ end’ arteries which
