SULPHUROUS ACID AND SULPHITES. 779 



The second after subperiod opened with the subject's temperature 

 at 98.6 F. and pulsations 79 per minute. He reported a headache 

 during the entire day and a u bad feeling in the stomach." The head- 

 ache continued during the following two days, temperature for these 

 days being somewhat below normal, 98.1 F. and pulse 78 beats per 

 minute. The after period closed with the subject feeling well, tem- 

 perature and pulse normal. His average body weight for this sub- 

 period was 58.21, and for the entire after period 58.43 kilograms. 



The examination of the urine showed a " small quantity" of albumin 

 throughout the entire observation; this is evidently pathological in 

 this case, as the same is reported in the previous series of which No. 6 

 was a member ; the microscopical examination is not so alarming, a 

 large number of mucous cylindroids and a few casts being found. As 

 a whole, the urinary examination would point to the existence of a 

 slight nephritis which had been of long standing.

This subject was in excellent physical condition and had had no 

 illness of any nature during the period of relaxation. His heart 

 action and kidneys were normal; temperature somewhat subnor- 

 mal, but uniformly so. The normal condition continued throughout 

 the fore period, his average body weight for that time being 70.46 

 kilograms. 



On the last day of the first preservative subperiod the subject 

 reported a slight headache during the afternoon; there was no change in 

 temperature or pulse and the body weight was practically the same as 

 in the last fore subperiod. The average weight for this preservative 

 subperiod was 70.02 kilograms. 



No. 7 complained of a headache at the beginning of the second pre- 

 servative subperiod, but this symptom disappeared by the following 

 day. On the third day of the period he felt tired, especially in the 

 lumbar region, and on the following day had a recurrence of headache 

 accompanied by dizziness and feeling of weakness. His temperature 

 and pulse were somewhat higher on this day. His body weight 

 remained practically the same, averaging 70.06 kilograms for the 

 subperiod. 



In the third preservative subperiod this subject complained of feel- 

 ing weak and tired, with a dull, depressed sensation; also of intense 

 pain in the region of the kidneys. His average weight for this sub- 

 period was 69.95 kilograms, a slight loss as compared with previous 

 records. The administration of the preservative was discontinued 

 at the beginning of the fourth subperiod, as the subject still com- 

 plained of pain in the region of the kidneys and some headache. In 

 fact, by the middle of the fourth preservative subperiod these feel- 

 ings of uneasiness, combined with a vivid imagination, resulted in
