To verify the personal impressions regarding the scholastic work of the men who served as subjects in the experiment, we have the more or less objective data of the term grades in the several college courses which were taken. The experiment lasted from October 4 to February 3. The college year is divided into three terms - fall term, from September 19 to December 21; winter term, from January 3 to March 22; and spring term, from April 2 to June 1. The fall term and the first part of the winter term were thus included in the diet period. In table 200 the average term grades for the fall and winter in all the courses taken are compared for each subject with the average of all the grades which the subject had received in all the courses taken previous to September 1917. Of Squad A, 9 men were from the senior class, but Fre should not be counted in any comparison, since he served in the squad so short a time; there are thus 8 men whose records are comparable. Of these, 4 (Can, Gul, Pec, and Vea) show average marks for the diet period which are slightly below their average for all courses preceding September 1917. There are 4 (Bro, Gar, Moy, and Tom) who show marks as good or better for the diet period. Changes are not large in any case, the largest is one of 4 per cent in the case of Moy, whose previous average grade was 87 and whose average grade during the low diet was 91. The whole group of 8 senior subjects taken together show average grades which are identical for both periods, that is, 88.6 per cent. There were 31 other men in the senior class. The average grade for all of these men, prior to September 1917, was 86.3 per cent, and for the same group, during the period of the experiment, the average was 84.3 per cent. There was thus an average decrement of 2 per cent for those who were not subjects. If this tendency of the class as a whole during the first two terms of this year as compared to the record for previous years is contrasted with the average record for the 8 senior men who were subjects in Squad A, it is perfectly justifiable to say that these men did not do work that was inferior to their previous college work, and their performance was in no way below that of their fellows. Three of the subjects of Squad A were classified as sophomores; these were Mon, Pea, and Spe, as shown in table 200. The average grade in the case of these 3 men shows in each instance a better average grade during the period of the experiment, with the result that the 3 men have an average grade of 83.7 per cent for courses prior to September 1917, and for courses during the experiment, 89.0 per cent, an average difference of 5 per cent in favor of the work done during the experiment. The average for 27 fellow-classmen shows an average grade of 83.0 per cent prior to September and an average during the experimental period of 87 per cent. Here is a difference of 4 per cent in favor of the work done this college year. The three sophomores in Squad A, therefore, show the same tendency as the rest of their class, but slightly more marked. Hence after a careful analysis of the term grades for the many courses which had previously been completed and others which were taken during the period of the experiment by these men, it was found that, as a group, during the 4 months' period of reduced diet, they kept their college work up to their own previous standard, and were not inferior to their fellow classmen. The statement of Professor Berry and some of the men that the college work was of usual standard is therefore clearly verified.

1Many things concerning the light side of the experiment and the attitude of the men to it could be mentioned. On the floor of the library at the Nutrition Laboratory, one Monday morning, one of us picked up a slip of paper bearing the following couplet: "Die, die, Diet Squad; Shy, shy, shy a 'pod,'" by which it is meant to be indicated that the girth has been remarkably reduced. Squad A, when the experiment was nearing the close placed a calendar over their table in the dining hall, which bore in large letters the words: "Ten days, and we eat." Each day, to the accompaniment of applause and congratulations, the number of days was decreased one.
