SUMMARY FOR NINE MEN. 



Average figures in this column show the averages per man per day. 

 PRESENCE OF ALBUMIN AND THE REACTION OF THE URINE. 



The urine was also examined for albumin, and its reaction was deter- 

 mined from time to time during the progress of the experiment. The 

 quantity of albumin present at each test was not estimated, the exam- 

 ination being confined to ascertaining its presence. In Series VI, 

 therefore, a comparison as to the relative quantity of albumin present 

 in the three periods can not be made, as was done in Part I in the case 

 of boric acid. The degree of acidity was determined in terms of 



standard alkali. 



No. 1. 



There is no albumin in the urine of No. 1 at the beginning of the 

 fore period, but at the end there is a minute trace. There is no appear- 

 ance of albumin during the preservative period. The reaction of the 

 urine in this case is amphoteric in the fore period and was not deter- 

 mined in the other periods.
