[16]: Numbers refer to cases as listed on Table II. of the test group growth is greater than that of the control group. The three nutrition pairs show the following records of growth,--in number 7, the test case shows a growth of..6 in. more than his control. Number 10 is the pair in which the growth is equal. In number 11 the test case again exceeds in growth by .6 of an inch. More reliable than height and weight considered separately, as an index of physical welfare, is weight in relation to height and age. Table V shows the improvement in this relationship for the two groups. The numbers in columns 1, 2, 4 and 5 show the per cent under or over weight of the individual cases, in relation to their respective heights and ages. The authority upon which the figures are based, is the table published by the American Child Health Association, giving standard weights for height and age in boys.
