preservative period closed November 27, showing an average weight 

 of 67.66 kilograms, a slight decrease as compared with the fore period. 



The after period began with a weight of 67 kilograms, temperature 

 and pulse normal. No. 2 speedily regained his normal feelings, 

 although on the 30th he had considerable headache and again felt sen- 

 sations of nausea. These feelings passed away on the 1st of Decem- 

 ber and an increased appetite was developed, although the weight 

 continued to fall. On December 2 the patient complained of being 

 still hungry after having eaten three normal meals during the day. 



The first day of the second after subperiod was characterized by 

 unpleasant sensations, nausea, and general discomfort during the 

 afternoon. This continued on the following day. The symptoms 

 were better on the 5th of December, the nausea having entirely 

 passed away at that time. Only normal symptotus were exhibited 

 from that time until the end of the after period on December 7. At 

 this time the subject was perfectly well, temperature and pulse nor- 

 mal, but continued to lose weight, as the last recorded weight was 

 66.65 kilograms and the average for the after period 66.79.

This subject at the time of the beginning of the fore period was in good 

 plwsical condition, although of a rather small stature, having a weight 

 of 52.78 kilograms, normal pulse and temperature. There was a slight 

 rise of temperature on the 21st of October, and also a considerable 

 quickening of the pulse, showing a decidedly feverish condition. This 

 indisposition developed to such an extent that No. 3 did not report for 

 observation at the table until October 26. On the 26th the fever still 

 continued, the pulse was above the normal, and his weight had fallen 

 to 50.54 kilograms. On the 28th of October there had been some 

 improvement in the subject's condition and his pulse and temperature 

 were only slightly above the normal. Owing to this illness the ana- 

 lytical data of the fore period are without value and the time of the 

 first preservative subperiod, October 29 to November 2, became, in 

 the case of No. 3, the fore period, at the beginning of which the tem- 

 perature and pulse were normal and the weight 50.34 kilograms. No 

 medical symptoms of any significance were developed during the fore 

 period. The pulse and temperature remained practically normal and 

 the weight had increased at the end of the period to 50.43 kilograms, 

 the average for the period being 50.42. During the first preservative 

 subperiod (November 3-7 in the case of this subject) the pulse and 

 temperature were normal and the weight slightly increased, the aver- 

 age being 50.73 kilograms. The appetite of No. 3 increased very 

 markedty during this subperiod and he was still hungry after the three 

 regular rations had been eaten. A slight cold developed on the 5th of 

 November, but was not of any consequence. At the end of this sub-
