URINE. 315 



An analysis of the blood of this person has been given in 

 Vol. I., page 330. 



In common or chronic icterus, where, instead of there being 

 febrile symptoms, the pulse becomes slower as the disease ad- 

 vances, the urine is at first of a dark red colour, after a time 

 it becomes of a dark brown, and often, according to Schonlein, 

 of an inky tint j towards convalescence it clears up, and gra- 

 dually returns to the normal state. 



I made an analysis of the urine of a man suffering from 

 icterus, anasarca, and haemoptysis, who was being treated in our 

 hospital. 



This analysis corresponded closely in its results with the 

 preceding one. 



The urine was of a brownish red colour, very turbid, had an 

 acid reaction, and deposited two layers of sediment, the under 

 one of a lateritious appearance, and the upper of a brown 

 colour; both consisted of urate of ammonia coloured partly 

 with uroerythrin and partly with biliphsein. The urine be- 

 came perfectly clear on being heated, and at the boiling point 

 gave no indications of albumen. Nitric acid caused no preci- 

 pitate, but produced the well-known shades of colour dependent 

 on the presence of bile-pigment. The specific gravity was 1014. 



The urine contained : Analysis 148.

The urea in this case amounts to only 29 of the solid re- 

 sidue, and the uric acid independently of the urate of am- 

 monia to 2'7g, the latter alone amounting to 9 : the salts are 

 diminished, with the exception of the earthy phosphates which 

 are increased and amount to 2g. 



[Scherer 1 mentions a case of long-standing icterus, dependent 

 apparently on chronic inflammation of the parenchyma of the 

 liver, in which the urine, on emission, was clear, yellow, and 

 perfectly neutral, but after standing three or four hours became
