URINE. 279 



whose pulse was 104 and full, the urine was very scanty, of a 

 dark-brown colour, strongly acid, threw down a yellow sediment 

 spontaneously, and had a specific gravity of 10.23-1. 

 It contained : 



Water . . . .961-7 



Solid constituents . . . 38-3 



Urea .... 11-7 



Uric acid . . . 1-3 



Fixed salts . . . 9'2 



Extractive matters . . 15'7 



In five cases in which the morning urine was daily examined 

 with care, the characters of inflammation were present in a very 

 high degree: the specific gravity varied from 1021 to 1025. In 

 four of these cases the urine threw down a reddish sediment, 

 and in two a little albumen was occasionally present. 



In scarlatina, the urine at the commencement, while there is 

 considerable fever, is of a deep dark-red colour, and possesses 

 all the properties of inflammatory urine. 



In children the urine is always less coloured than in adults, 

 and its colour in this disease is proportionally less dark. 



It almost always has an acid reaction, and only exhibits a 

 tendency to become rapidly ammoniacal, when the disease is 

 associated with a nervous or septic condition of the system. 

 Any sediments that may be formed consist, for the most part, 

 of urate of ammonia and uric acid mixed with a greater or less 

 quantity of mucus : blood-corpuscles are occasionally noticed. 

 When the urine is ammoniacal, viscid whitish sediments of the 

 earthy phosphates are deposited, and if there is much gastric 

 disturbance the urine becomes jumentous. Albumen is com- 

 monly but not always found in the urine during the period of 

 desquamation. Dropsy may even supervene without the urine 

 becoming albuminous : it is sometimes preceded by the occur- 

 rence of hsematuria. 



Becquerel found that the urine during the febrile period was 

 generally very high coloured, and, if severe angina was present, 

 was very acid, and was either turbid, or became so on the 

 addition of an acid : it frequently also formed a gray or lateri- 

 tious sediment, and the presence of a small quantity of albumen
