any very consistent tendency toward improvement. The question, whether or not the results are affected by the differences in time interval, will be considered later.

In weight, the test group showed an average gain of 11013 pounds, with a median of 91 (Table XV). The average gain of the control group was 9113 pounds and the median 68. The gains in the test group are less variable than those of the control. The average of the gains of the test group in excess of those of the control is 19 pounds, and the median is 22 pounds; while the unreliability of the difference is 146 The average, then, is only 130 P. E. and the median 151 P. E.

If we turn to Table III and compare the results there set forth with the results at the end of the second period, we find the gains of the test group exceed those of the control in the following manner.

After a twelve months' interval, therefore, the actual average and median gains are slightly larger than after the first six months, but the variability is very much greater. Therefore, when expressed in terms of P. E., the gains are smaller. One of the test group cases (No. 13) who had gained 8 pounds after six months, gained 14 pounds in the second period of six months, making a total gain of 22 pounds. This gain is exceeded, however, by one in the control group (No. 12) who gained 35 pounds in six months, and 251 pounds more in the ensuing five months.

This is certainly an enormous gain for five months, under any circ.u.mstances. Turning to Table XIV we find no corresponding gain in I.Q. for this child. Indeed there is a loss of five points.

Other children in the test group who made large gains, were case 12, with a gain of 185 pounds after twelve months, compared with 45 pounds after six months; case 19, gain of 63 pounds after first six months, and 18 pounds after 12 months; case 21, whose gain after the first period was 58 pounds, but who gained 148 pounds after twelve months.

In these cases the gain in the second period greatly exceeds that for the first.
