210 THE SECRETIONS: 



lation, an inflammatory crust three fourths of an inch thick. 

 At the fourth bleeding, when five pounds of blood had been 

 abstracted, the inflammatory crust was one fourth of an inch 

 thick, and the clot very firm. The urine now discharged (about 

 thirty-six hours after the first bleeding) could hardly be consi- 

 dered darker than in health : it had an acid reaction, was devoid 

 of albumen, and had a specific gravity of 1018. It was composed 

 of the following constituents : Analysis 99. 



Water .... 960-10 

 Solid residue . . . 39-90 



Urea .... 17-50 

 Uric acid . . . 0-99 



Extractive matters . . 15-10 



Fixed salts . . . 3-65 



If we calculate the ratios of these constituents in relation to 

 100 parts of solid residue, and compare the numbers with the 

 normal average, we shall detect in the first analysis the elements 

 of a true inflammatory urine : the urea considerably exceeds 

 the physiological average, the fixed salts collectively are dimi- 

 nished, while the sulphates are only a little below the normal 

 standard, and the uric acid and extractive matters are increased. 

 We see, at the same time, the effect produced upon the consti- 

 tution of the urine by decided venesection.

[Zimmermann 1 found fibrin in the urine of a patient with 

 " endocarditis of the right ventricle at the period of the com- 

 mencement of hypertrophy." The urine was very variable in 

 its characters, sometimes normal, sometimes sedimentary, and 

 sometimes coagulable. In the latter case it was pale, and rapidly 

 became alkaline.] 



Phlebitis uterina. 



I have had several opportunities of examining the urine in 

 phlebitis uterina. In one instance occurring in our hospital I 

 found it of a dark colour, an acid reaction, and depositing a
