The first break in the descending hne is at November 15, i. e., after 

 the unrestricted meal on Smiday, November 11. This rise after a 

 Sunday meal was also noted in the curves for Bro and Can. The 

 irregular fluctuations in the next three weeks are somewhat difficult to 

 interpret, for at this time the subject was on a very low diet. It was 

 during this period that the trouble with his nose occurred. As may 

 be noted from the subject's personal history (see p. 48), his nose 

 was injured in a ball game on November 18. On November 30 he 

 entered the hospital for an operation on the nose, when a piece of bone 

 was removed. He was discharged from the hospital on the evening of 

 December 1. As a matter of fact, the increments in the body-weight 

 curve during the period of irregularity amount to a sum total of but 

 500 grams, which is probably not significant, and the general tendency 

 is toward a lower level. A slight rise is evident after November 25,

when an unrestricted meal was again taken. Evidently this subject 

 adhered rigidly to a low diet during the Thanksgiving recess, for 

 when he returned to college his weight was somewhat lower than the 

 weight recorded on November 25. A marked drop in weight followed, 

 which was so rapid and so consistent that it was decided that the 

 calories could be safely increased. During his absence from college 

 for the Christmas hohdays (December 20 to January 12), there was a 

 large increase in his weight of somewhat over 5 kg. The diet was 

 again somewhat reduced, and this reduction, combined with excessive 

 exercise and hard work, produced a rapid and consistent change until 

 the weight had fallen to a fairly constant level at somewhat above 62 

 kg. for the last 14 days of the experiment. Another operation on the 

 nose was performed on January 22, when a second portion of bone was 

 removed.
