BORIC ACID AND BORAX. 

 TABLE XXVIII. Effect of temperature upon volume of urine 



179 



To determine the general effect of the preservative upon the volume 

 of urine eliminated it will be necessary to combine, as in the other cases, 

 the data for the different series, which is done in the following tabular 

 statement, omitting Series II. 



TABLE XXIX. Influence of the preservative on volume of urine secreted. 



a To secure the average the number of days in each period is multiplied by the number of men in 

 the series, and the volume is multiplied by the factor thus obtained. The resulting products are then 

 added and finally their sum is divided by the sum of the factors. 



A study of the averages of the above data shows that, compared with 

 the fore period, there is practically no difference in the volume of urine 

 secreted during the administration of the preservative. The data do 

 not warrant any definite conclusion except of a negative nature, with 

 a possible exception of suggesting that there may be a very slight 

 impairment of the ability of the kidneys to secrete the urine by reason 

 of the administration of borax and boric acid. This conclusion, how- 

 ever, is only tentative, and the data on which it is based do not warrant 

 any more pronounced interpretation.
