SALICYLIC ACID AND SALICYLATES, 513 



that the condition of No. 12 was such that the salicylic acid adminis- 

 tered had a medicinal value, and shows the fallacy of depending on 

 individual results in such a study. These figures, whatever their 

 explanation, receive full weight in the summary for nine men given 

 in Table V. The data for the three men excluded, Nos. 3, 9, and 10, 

 while given in detail, are not included in the averages of the summary 

 for the reason that illness on the part of No. 3 rendered the data in 

 his case not strictly comparable, and certain marked irregularities in 

 the balances for Nos. 9 and 10 could only be explained on the basis 

 that they had violated the rules of observation and so invalidated the 

 data. 



The data for the nine men, averaged by periods, are as follows: 



Body weight for the fore period, 62.71 kilograms; moist food con- 

 sumed, 2,601 grams; dry food, 555 grams; mean percentage of body 

 weight represented by the moist food, 4.15; by the dry food, 0.88. 



For the entire preservative period the average weight of the nine 

 men is 62.27 kilograms; the amount of moist food consumed daily, 

 2,661 grams; the amount of dry food, 564 grams; the average per- 

 centage of the bod} r weight represented by the moist food is 4.27, and 

 by the dry food, 0.91. 



In the after period the average daily weight for the nine men is 

 61.61 kilograms; the amount of moist food, 2,579 grams; the amount 

 of dry food, 568 grams; the average percentage of the weight of the 

 body represented by the moist food is 4.19, and by the dry food, 0.92. 



This summary shows that the average body weight declined con- 

 sistently throughout the experiment, the average total loss of weight 

 being 1.1 kilograms. The quantity of dry food consumed, however, 

 gradually increased, rising from 555 grams for the fore period, to 564 

 in the preservative period, and to 568 in the after period, an average 

 daily increase of 9 grams during the preservative period and 4 grams 

 additional during the after period. These data show a distinct ten- 

 dency as a whole on the part of the preservative to diminish the 

 weight of the body notwithstanding an increase in dry food consumed. 



The graphic presentations of the variations in body weight as dis- 

 cussed above and given in the tables are to be found in figs. 1 and 2.
