318 THE SECRETIONS: 



Four days afterwards, when the vomiting was partially 

 checked by the use of morphia, the urine was turbid and ju- 

 mentous : it continued acid, and subsequently formed a copious 

 sediment of urate of ammonia, while the clear urine above the 

 precipitate was so dark that bile-pigment was suspected to be 

 present, which, however, was not the case. The urine conti- 

 nued to throw down sediments till the death of the patient, 

 which occurred not long afterwards ; it became, however, of a 

 brighter colour. 



Becquerel observes that in cancer of the stomach he has 

 found the urine normal, when there has been but little func- 

 tional disturbance : dark, sedimentary and very acid, when there 

 has been severe pain and frequent vomiting : and, finally, he 

 has found it anaemic in cases in which the physical powers have 

 been reduced to the lowest ebb by the disease. 



In cancer of the liver, Becquerel found the urine undergo 

 the same modifications that I have described as occurring in 

 cancer of the stomach. It was very dark, very acid, of high 

 specific gravity (1023 1026), and threw down a copious red 

 sediment. 



In cirrhosis of the liver, Becquerel found the urine much the 

 same as in cancer, except that when the cirrhosis was accom- 

 panied by icterus, bile-pigment found its way into the urine. 



[I am indebted to Dr. Percy for the following analysis of the 

 urine of a man labouring under deep and permanent jaundice 

 consequent on true carcinoma of the liver, of which he died. 



The urine contained in 1000 parts : 



Water .... 979-00 



Solid residue .... 21-00 



Urea .... 3-76 



Indeterminate organic matter . . 8-78 



Salts soluble in water . . 8-18 



Salts insoluble in water . . 0-28 



It was deeply tinged with bile-pigment, but deposited no 

 sediment. 



The small amount of urea may be accounted for by the fact 

 of great emaciation consequent on long previous mal-assimila- 

 tion, and the small amount of metamorphosis of tissue occur- 

 ring in the patient.]
