THIS paper represents data concerning comparative heights and weights of Paris school children, as recorded by school doctors and nurses, before and after the five years of restricted dietary intake incident to the war.
The survey of the records of 2,595 children, of whom 1,299 were boys and 1,296 were girls, was carried out in the following way: The
heights and weights of children from 6 to 16 years of age were taken at random in a certain number of schools in 1938 and 1944. The averages for 1938 and 1944 for each year of age were then determined, as given in the accompanying table and plotted on charts 1 and 2. The smooth lines on the charts indicate the weights and heights per year of age below which 10, 25, 75 and 90 per cent of children in the United States will fall on the basis of the statistical
