The important point in selecting the ration was to secure a uniform 

 ingestion of nitrogen. Table I shows that No. 1 consumed for break- 

 fast 6.66 grams of nitrogen, for luncheon 1.52 grams of nitrogen, and 

 for dinner 7.48 grams of nitrogen, making a total of 15.66 grams per 

 day. No. 2 had for breakfast 5.13 grams of nitrogen, for luncheon 

 1.77 grams of nitrogen, and for dinner 9. 04 grams of nitrogen, making 

 a total of 15.94 grams of nitrogen per day. No. 3 consumed for break- 

 fast 6.66 grams, for luncheon 1.52 grams, and for dinner 8.53 grams, 

 making a total of 16.71 grams per day. The periods of observation 

 were short in order to avoid any dislike of the food which might have 

 occurred had so uniform a diet been enforced for a long time. The 

 fore period covered only three days, the period of administration of 

 the salicylic acid six da} 7 s, and the after period three days, making 

 altogether a period of twelve days of observation. During the first 

 preservative subperiod of four days 0.25 gram of salicylic acid and 

 during the second subperiod of two days 0.50 gram of salicylic acid 

 is administered daily. The results obtained in the preliminary study 

 are given in Table II. 



ANALYTICAL RESULTS. 



INDIVIDUAL DATA. 



No. 1. 



In the case of No. 1 the average volume of the urine excreted daily 

 in the fore period is 967 cc. The average daily quantity for the entire 

 preservative period is 1,008 cc, and for the after period 1,107 cc.
