288 THE SECRETIONS: 



1000 parts contained 24*25 of solid residue, of which 9-01 

 was urea, and 2*2 uric acid. In the first of these cases the 

 urea amounted to 37'4g of the solid residue, and the uric acid 

 to 5'1 ; in the second the urea amounted to 37'2g, and the uric 

 acid to 9, proportions which, as far as the amount of urea is 

 concerned, approximate to those of inflammatory urine. 



An analysis of the urine of a man aged 30 years, who was in 

 the colliquative stage of tubercular phthisis, gave very similar 

 results, except as regards the specific gravity. 



The urine was brown and turbid, had a very acid reaction, 

 and deposited a purulent-looking yellow sediment of urate of 

 ammonia. The specific gravity was 1026-6. 



1000 parts contained : 



Analysis 128. 



Water , . . 935-92 



Solid constituents . . 64-08 



Urea . . . 23*90 



Uric acid . . . 2-40 



Fixed salts . . . 10-85 



Of these 10-85 parts of fixed salts 1'3 were earthy phos- 

 phates, and the sulphates formed only a small part. The urea 

 amounted to 37'3, and the uric acid to 3-7 of -the solid con- 

 stituents, the urea being as nearly as possible the same as in 

 Becquerel's analyses. 



The increase of uric acid is of great interest; it is particularly 

 striking in Becquerel's analyses : other observers have noticed 

 this fact in adults suffering from tubercular phthisis, and 

 Schonlein, moreover, has directed attention to it. 



[I am indebted to Dr. Golding Bird for the following case. 

 A man aged 24 years, in the early stage of phthisis, (tubercular 

 depositions but no cavities,) passed in the course of twenty -four 

 hours, forty-five ounces of urine of specific gravity 1020. 



The water amounted to . . . 19125 grains. 



The solids . . . .936 



Urea .... 328-5 



Uric acid . . . . 4-5 ] 



In renal and vesical phthisis the urine contains a greater or 

 less quantity of pus. 



It is usually pale, turbid, and very quickly takes on an alka- 

 line odour, especially in phthisis vesicse, in which, even on
