Mr. W. ADAMSON
A total of 20,000 children in 68 schools of the Lanarkshire education authority will be included in the present investigation into the value of an additional daily ration of milk in the dietary of the school child. Of these children 10,000 will receive milk and 10,000 will receive no ration but will be weighed and measured for comparison. The present investigation follows the two years investigation on a small scale eon-ducted in 1926–1928, and reported in the annual report of the Scottish Board of Health for 1928. The results of that investigation showed that the addition of milk to the diet produced a marked improvement in the physical condition of children of all school ages and justifies an investigation on a scale sufficiently large to give conclusive results.
