feeling of nausea the night before and a mild pain in the stomach 

 during the night and day. The sensation of drowsiness continued. 

 His temperature throughout this subperiod shows a tendency to be 

 below normal; pulse normal. The average body weight for the sub- 

 period was 61.55 kilograms, a loss of 0.44 kilogram. 



In the fourth preservative subperiod No. 8's symptoms were about 

 of the same nature as those of the previous period. He experienced 

 occasional headache and nausea, and the feeling of drowsiness still 

 continued, though he was getting his regular amount of sleep. His 

 temperature was occasionally subnormal; pulse remained normal and 

 very constant throughout. His average weight for the period was 

 61.74 kilograms, the average for the entire preservative period being 

 61 .73 kilograms. 



In the first after subperiod No. 8's symptoms were as varied as 

 usual; he was still in a somewhat depressed condition, which gradually 

 wore off. His appetite toward the end of the period returned, but he 

 still complained of being drowsy and seemingly not able to get a suf- 

 ficient amount of sleep. The average weight for this subperiod was 

 61.78 kilograms. 



No. 8 was practically normal in the second after subperiod; his 

 temperature was subnormal on one or two days; pulsations normal 

 throughout. His average weight for this subperiod was 61.88, and 

 for the entire after period 61.83 kilograms. While this subject was 

 the weakest man, physically, in the class^ he seemed to stand the 

 effects of the preservative better -than any of the other members. 

 The excessive quantity of water he drank allowed of a greater dilu- 

 tion of the preservative and a more rapid elimination, which undoubt- 

 edly is the explanation of his ability to withstand its action, though 

 he developed symptoms of headache, nausea, dizziness, and loss of 

 appetite during part or whole of the preservative period. He showed 

 a slight gain in weight throughout the entire period of observation.
