344 Dr. Vsivkes on the Elimination of Nitroffen, [Jan. 31, 



The full details are given further on, and I will now merely state the 

 mean results. 



On the mean of the two days the urea of twenty-four hours fell from 

 35 grammes to 16-765, or more than one-half in the case of S., and from 

 26 to 15, or rather less than one-half in the case of T. 



The amount of urea in the last twelve hours was only 5 and 4*2 grammes 

 for the two men. The total nitrogen, or a mean of the two days, fell from 

 17*97 and 13*4 to 8*176 and 7 grammes in the two men, while in the last 

 twelve hours it was only 3-017 and 2*17 grammes, or at the rate of only 

 6-034 and 4*34 grammes in twenty-four hours.

A more satisfactory comparison may perhaps be made by taking the 

 last day only as representing more complete nitrogenous inanition.

Therefore during complete nitrogenous inanition the tissues of the 

 smaller and older man furnished a slightly greater amount of nitrogen 

 than those of the larger man, and this is evident both in the ureal and non- 

 ureal nitrogen, so that it could scarcely be accidental. 



The sulphuric acid and phosphoric acids were determined on the last 

 day; the latter acid was in almost precisely the same absolute mean 

 amount in each man, viz. '9533 and '941 gramme ; the larger man passed, 

 however, one-third more sulphuric acid, viz. '633 as against '4 2 7. gramme. 



In the last twelve hours the chloride of sodium fell to I and -42 

 gramme.
