1. The distribution of the carotid and vertebral arteries in the brain and spinal cord of the goat have been determined by the infusion of coloured suspensions in the living animal and subsequent histological examination of the tissues. 2. Blood flow in the basilar artery is in a caudal direction so that the brain is virtually entirely supplied by carotid blood; in some individuals vertebral blood may reach the posterior medulla. 3. The carotid rete does not provide admixture of blood from the two carotids under normal conditions of inflow, and this is so whether the animal is anæsthetized and supine, or conscious and standing in normal posture.
