1. In our examined subjects, the A. recurrens anterior was found to be more frequently doubled than as has been reported. 2. The number of central rami arising from the A. cerebri media varies between 3 and 13. 10% of these already divide extracerebrally so that the number of small asts actually present lies between 4 and 20. The count presented by Lazorthes appears to be based on the former method and by Jain on the latter. The ramifications arise from the main artery as well as from its insular branches. Arterial trunks are likewise often present that give off a large portion of the asts. When operating aneurysms of the A. cerebri media, these facts are of importance to the neurosurgeon who must sprare these vessels whenever possible. Should more of these branches or one of these arterial trunks be bound with a clip, serious neurological deficits will occur.
