“…The fact that most of the intelligence quotients are below 100 suggests that a large number of them may have been in a slight degree mentally handicapped. Levine and Gordon (1942), in a study of great interest on the physiological handicaps of the immature infa-nt, point out that the tendency to haemorrhage is due not only to the persistence of the foetal type of capillaries (the archicapillaries of Capper) and the deficiency of vascular elastic tissue, but also to the fragility of the immature capillaries, the low prothrombin content of the plasma, the low body reserves of vitamin C, and the damaging effect of anoxia on capillary integrity. Tow (1944) is of the opinion that most of the cerebral injuries inflicted on the immature child are due to cerebral anoxia.…”
