Two monkeys (Macacus rhesus) were observed on their usual normal diet over a period of six weeks. They were then placed on a diet complete except for absence of vitamin G. Observations were repeatedly made over a period of 111 days, at the end of which the animals were sacrificed and autopsied. Data were collected on the effects of this diet on the bacteria, fungi, and protozoa of the stools; on the oral blood sugar tolerance, the blood count, the gastric acidity, the weight, gastro-intestinal x-rays, gross pathology post mortem and histology of the intestine.
