Arranging them by the average absence of the suppressed image we have this order: B. 251.08 sec D. 193.89 " H. 81.02 " C. 62.07 " I. 59.72 " K. 31.83 " J. 31.75 " G. 19.47 " A. 10.44 " F. 10.09 " It is to be remarked, however, that the ability to keep the suppressed image out of the field increased with practice and that A. and F. had less than half the number of experiments that the rest had. D., who had but two thirds as many as most of the other subjects and therefore had less practice in suppressing the image, stands yet second in respect to this ability. If we compare the subjects with regard to _first_ efforts and _first_ absences only, we obtain the following orders: According to Ave. Time req. According to Ave. Absence for first Suppression. of Image after first Suppression. J. 3.59 sec. B. 270.44 sec. B. 5.79 " D. 190.07 " C. 7.88 " F. 86.07 " I. 9.77 " H. 73.27 " F. 12.67 " K. 71.90 " H. 15.27 " I. 53.83 " K. 21.63 " C. 43.08 " G. 21.88 " J. 32.18 " D. 23.28 " G. 20.39 " A. 28.32 " A. 11.29 " Arranging the groups of images suppressed according to the average times of all suppressions and absences we have these orders: Suppression. Absences. Central Images, 5.41 Marginal Images, 125.12 Upper " 6.95 Sundry " 68.78 Left " 8.60 Left " 51.26 Right " 8.94 Lower " 50.04 Lower " 9.11 Right " 43.93 Marginal " 11.35 Upper " 32.35 Sundry " 12.09 Central " 26.54 SUBJECTIVE.
