Examination of the change of vitamin A level in blood serum after the administration of vitamin A preparations to healthy infants, showed that in those receiving the oily or aqueous preparation intramuscularly the change was irregular as compared with those receiving aqueous preparations per os. The aqueous vitamin A orally administered seemed to be absorbed better than parental administration. Investigation was made on the transition of vitamin A in spinal fluid in the infants suffering from tuberculous meningitis with an increased permiability of the spinal membrane, but the transition was not observed in the administration of 50,000 IU of vitamin A. A small increase was recognized in the fecal excretion of vitamin A 24 hours after the administration of the vitamin.
