We have therefore:

28 pairs of I.Q.'s to be compared 21 pairs of weights 19 pairs of heights 16 pairs of grip measurements 20 pairs of tapping speeds 24 pairs of Healy Completion scores.

Again, in only five pairs does the gain of the control exceed that of the test case, while in the remaining sixteen pairs the gains of the test cases are greater than those of their respective controls. The greatest loss of test as compared to control is 42 lbs., while the largest gain is 79. It would seem then, that after a six months'

interval a child who has been operated on for adenoids and tonsils will tend to show a slightly greater increase in weight than a child who continues to suffer from the defects. The very small group renders this conclusion far from a.s.sured. Since it doubtless takes some little time to recover from the effects of the operation, and since there is comparatively little gain in weight in a six months' interval, it would be well to extend the experiment over another year. For the greater reliability of results, some degree of after-care should be given the operative cases, the control cases of course receiving the same treatment. While this was impracticable in the present study, it happened that three pairs of cases were members of a nutrition cla.s.s, and therefore underwent some hygienic treatment. In one pair, (no. 11) the test case lost 3 of a pound, while the control gained 9. The test cases of pairs 7 and 10 gained 8 lb. and 21 lbs. respectively, over and above their controls. However, these three cases alone are of little significance.

A study of increase in height suffers even more than one of weight gains from the short interval which elapsed between measurements. Normally, there is very little growth in six months. There are only nineteen pairs of cases in this portion of the study, a fact which renders it of even less value. However, results are offered for what they are worth. The smallest increase in height (3 in.) is in the test group, while the greatest growth (35 in.) is also in the test group. There is, however, a gain of 33 inches in the control group as well as one of only 4 inches. There are seven pairs in which the test group growth is less than that of the controls, one in which the two are equal, and in the remaining eleven the growth of the test cases exceeds that of the controls. The variability
