Six months after operation for adenoids and tonsils, there seems to be a slight but not very reliable gain in weight as the result of the operation. After twelve months this has increased; indeed, it has very nearly doubled. 2. Gain in height, resulting from operation, is so slight as to be unreliable. This gain does not increase during a second period of six months. 3. The height-weight-age relationship is an excellent measure of the physical well-being of the child. The figures expressing this relationship show no very reliable gain in the first six months, but improvement increases considerably during the second period. 4. The test group shows no gain over the control group in strength of grip. There seems on the other hand to be a slight loss; which does not decrease in amount during the second period. 5. Speed of tapping did not increase during the first period, any more for the test group than for the control. During the second period, however, there is a marked improvement. 6. Operation for adenoids and tonsils does not lessen fatigueability as shown by the tapping test. The probability is, however, that the test is at fault. 7. No rise in I.Q., as a result of operation, makes itself evident after six months or after twelve months. 8. There is no improvement in the performance of the Healy test either after six months or after twelve.
