URINE. 267 



the left side, and died on the fifteenth day from the seizure. 

 It exhibited in a high degree, both in its physical properties 

 and in its chemical constitution, the characters of inflammatory 

 urine. The quantity was diminished ; the specific gravity, the 

 urea, and uric acid exceeded the physiological average. 



Quantity of urine in 24 hours, in ounces . ^ 25*7

Water ..... 960-40

In 100 parts of solid constituents there are 43-0 of urea, and 

 1*6 of uric acid. 



The urine of a man aged 31 years, who was treated in 

 Schonlein's clinical wards fora severe attack of pulmonary haemor- 

 rhage, was of a dark red colour, very acid, and exhibited the other 

 symptoms of the inflammatory type, from the period of admis- 

 sion to the eleventh day. On two occasions I found its specific 

 gravity to be 1023 and 1022. On the eleventh morning the 

 urine was rather turbid, and on the twelfth it became jumen- 

 tous from the urate of ammonia which was suspended in it ; it 

 still had a strong acid reaction, but did not form any sediment ; 

 on the next day, the sediment was very considerable. The 

 pulse was quick and feverish till the urine began to deposit 

 sediments; subsequently, the vascular excitement almost en- 

 tirely disappeared, and the urine became clear and pale, and 

 contained only a few mucous flocculi. 



In a girl aged 20 years, with severe hsematemesis, who had 

 brought up nearly a quart of coagulated blood, the urine which 

 was passed almost immediately after the attack scarcely differed 

 from the normal secretion ; but, on the following day, it was 

 pale, and scarcely acid, and it continued in this state for several 

 days. 



In hsematuria the urine contains blood, either in a coagulated 

 state or devoid of fibrin ; in the latter case, the blood-corpuscles 

 may be either perfectly dissolved or not ; and when they are 

 found floating in the urine, they form, after a short time, a red 

 sediment. More minute observations on this subject have been 

 given in page 187.
