If we calculate the amount of urea, uric acid, and fixed salts 

 in these analyses in relation to 100 parts of solid residue, and 

 compare the results with the physiological average which 

 Becquerel has given, the proportions to which I have already 

 alluded will plainly appear, that is to say, there is an absolute 

 and a relative diminution of urea and of uric acid, and an in- 

 crease of the fixed salts ; 100 parts of solid residue contain : 



Anal. 1. Anal. 2. Anal. 3. Normal Urine. 



Urea . . 32-0 33-0 24-0 42-0 



Uric acid . . 0-4 1-2 0-8 1-4 



Fixed salts . . 26-0 38-0 30-0 24-0 



The urine may exhibit some differences in its chemico- 

 physiological properties if other diseases are associated with 

 chlorosis, or if the latter is not very fully developed. The persons 

 from whom the urine in analyses 1 and 2 was taken were slightly 

 feverish. In analysis 3, the chlorosis was combined with pul- 

 monary emphysema. In analysis 4, there was some affection 

 of the nervous system. 



With the exception of a considerable diminution in the 

 quantity of urine discharged in twenty-four hours in analyses 1 

 and 3, and the increase of uric acid in analysis 2, there are no 

 particular deviations in the relative proportions of the solid con- 

 stituents from the statement that we have previously made ; for 

 the urea is both absolutely and relatively diminished, and the 

 salts occur in a higher proportion than in normal urine.
