The first after subperiod began on November 28 and ended on 

 December 2. On the first day of the after period the subject com- 

 plained of a slight cold and sore throat. There was no perceptible 

 rise in temperature, however. The cold continued in a mild degree 

 on the 29th. but the temperature was slightly below the normal. The 

 temperature was normal on the 30th, with slight cold continuing. The 

 feeling of hunger had disappeared and did not return on December 

 1 and 2. The average weight for the first after subperiod was 52.42 

 kilograms. 



The second after subperiod began on December 3 and ended Decem- 

 ber 7. A slight cold was reported on the 3d, with temperature slightly 

 below the normal. On the 4th the slight cold continued, with almost 

 normal temperature. On the 5th the second observation of tempera- 

 ture was slightly above normal, 99, with the pulse at 80. On the 6th 

 all symptoms of cold had disappeared and no sense of hunger was 

 experienced. On the 7th the temperature was normal and the hunger 

 symptom occurred after dinner. The average weight for the second 

 after subperiod was 52.31 kilograms, and the mean weight for the

 apparent. The temperature before dinner was perhaps slightly below 

 the normal, the average being only a little above 98. The average 

 weight for the first fore subperiod was 68.43 kilograms and for the 

 second subperiod 68.21 kilograms. The final weight on the last day
