A study of blood levels, urinary excretion of several vitamins, and fat balance was made in apparently healthy rhesus monkeys kept on a purified diet. For the same daily intake of thiamine, riboflavin, and pyridoxine (about 1 Mg/ day) there was excreted a greater quantity of riboflavin (about 0.32 mg/day) than of pyridoxine (about 0.025 mg/day) or of talamine (about 0.17 mg/day). On an intske of 20 to 30 mg/day of niacinamide about 1 mg/day was excreted as Ni- methylnicotinamide. On a daily ascorbic acid intake of 50 mg only 2 to 3 mg/day of ascorbic acid were found in the urine. The average excretion of pteroylglutamic acid ranged from 0.003 to 0.014 mg/day on an intake of about 0.2 mg/day. Determinations on serum samples revealed average levels of about 197 I.U.% of vitamin A, 6 mu g% of carotene (carotene-free diet), and 0.77 mg% of ascorbic acid. With 5% fat in the diet only 2.8 to 8.5% of the ingested fat was lost in the feces. The fecal fat concentration ranged from 6.1 to 13.4% of the dry weight of the feces. Because of the variation in fecal fat loss in an individual monkey from one collection period to another, a long balance period is a more reliable index of fat absorption than a short-time study.
