In October 1930 Tisdall, Drake and Brown1 described a new cereal mixture which was rich in vitamins and mineral elements. They felt that the finely milled and refined products ordinarily used were deficient in many of the minerals and in all of the vitamins. Since the cereals form from 30 to 60 per cent of the daily caloric intake, the constituents of this component of the infants' diet deserve serious consideration. With this thought in mind they devised a cereal mixture that more nearly fulfilled the requirements for vitamins and minerals without disturbing the caloric value of the carbohydrate. By feeding groups of rats diets poor in a single vitamin, symptoms characteristic of deficiency of vitamins A, B, D and E, respectively, were produced. The addition of their cereal mixture to these experimental diets was sufficient to bring about clinical improvement in the animals.
