 headache. This passed off, and he felt all right the next day and for 

 the remainder of the subperiod. Temperature and pulse were normal 

 after the first day. The body weight was 62.29 kilograms. 



He was feeling well and temperature and pulse were normal on the 

 first day of the third preservative subperiod. The following day he 

 complained of a pain in the chest, and noted that he had passed a 

 much larger quantity of urine for the day, i. e. 1,730 cc. He felt
