The experiment here described was conducted in connection with other nutrition studies on a group of malnourished children, residents of the California State School for Deaf and Blind at Berkeley. The work was designed to supplement other studies on the comparative effects of certain supplementary lunches in the treatment of undernourished children. The subjects were given a medical examination at the beginning and end of the study; weight, height, hemoglobin, alveolar carbon dioxide tension, vital capacity, chest circumference, chest expansion and hand-grip strength were taken at the beginning and end and at intervals throughout the feeding period, which lasted for eighteen weeks.

A record of the menus was kept, and notes were made as to the appetite of the subjects of this study.
The supplementary lunches were given at the same
