Where only milk or codliver oil is given a remarkable improvement is often effected. Indeed, several teachers told us that in their opinion the provision of milk was more beneficial than either breakfasts or dinners. At a Bethnal Green school, during the winter of 1909-10, it was found that out of 57 boys and 109 girls examined at the medical inspection, 24 of the boys and 61 of the girls were underfed. These children were given a tea-spoonful of codliver oil in a cupful of warm milk every day during the morning interval. At the end of the year the nutrition was re-assessed, with the following results:--[501] Footnote 501: Annual Report of London County Council for 1910, Vol. III., p. 130. Good. Average. Bad. 57 boys Before 4 19 34 After 26 28 3 109 girls Before 3 49 57 After 42 61 6 The results of these experiments are sufficient in themselves to establish conclusively the benefit to be derived from regular feeding even when no other factor in the child's environment is changed. "No doubt," says Dr. Haden Guest, "irregular and late hours, disturbed sleep, overcrowding, improper clothing and employment of children after and before school hours, do each and all exercise a very detrimental effect on the children of poor parents. But that the greatest influence for evil is exerted by improper and insufficient food is a matter over which it appears impossible to have great controversy."[502] Footnote 502: MS. Report by Dr. L.
