 experiment of 2.19 kilograms, in connection with which, of course, 

 the cold from which the subject suffered must be remembered. 



No. 7.J. N. B. 



At the beginning of the fore period the weight of No. 7 was 68.3 

 kilograms, and the temperature and pulse were normal. He was in 

 excellent physical condition, no organic disease of any of the vital 

 organs was found, and he had had no serious illness for a long period. 

 The first fore subperiod passed without any unusual incident. At the 

 beginning of the second subperiod the weight had fallen to 67.90 kilo- 

 grams, but no other disturbances were noted. At the close of the 

 fore period the weight was 67.55 kilograms and the average weight 

 for the fore period 67.91 kilograms. 



The preservative period opened with the subject in good condition, 

 though somewhat inclined to indulge in vivid imagination and to dis- 

 cover symptoms of trouble which did not exist. No unusual symp- 

 toms were manifested during the first preservative subperiod, but at 

 the close of the second subperiod the symptoms of hunger appeared, 

 the subject not feeling that the rations, which were entirely sufficient 

 to satisfy his hunger during the fore period, were enough. On 

 November 7 he first complained of indigestion, and at the beginning 

 of the third preservative subperiod was feeling reasonably well. 

 During November 9 a very bad headache was developed, which lasted 

 during the afternoon, and on the following day there was an uneasy 

 sensation in the stomach. The general appearance of the subject at 

 this time was not as good as at first, but no specific complaints were 

 made. During the night of November 12 the subject was feeling quite 

 ill and was not well throughout the following day. On the 14th the 

 symptoms of malaise had largely disappeared, but not entirely. 

 Headache developed again on the 15th, and the feeling of hunger 

 seemed to be accentuated. Insomnia was complained of on the night 

 of the 15th, and the statement was made that for two preceding nights 

 difficulty in sleeping, especially in the early morning hours, had been 

 experienced. Insomnia continued during the 17th, and the headache 

 also persisted during that day. On the 19th symptoms of indigestion 

 were clearly manifested, especially in the afternoon, but the sensation 

 of hunger still continued. On the 20th of November the symptoms 

 of indigestion increased, and the subject was feeling very ill. There 

 seemed also to be a slight depression of the temperature. On the 21st 

 the weight fell below 67 kilograms. The indigestion became more 

 pronounced, and the headache also continued. The appetite failed on 

 the 22d, and some difficulty was experienced in taking the full ration. 



At the beginning of the sixth preservative subperiod the weight
