220 THE SECRETIONS: 



pleuritis associated with pulmonary phthisis, and in fifteen 

 out of seventeen cases observed by him, there was considerable 

 effusion. In a man aged 36 years, with acute pleuritis, deli- 

 rium, and certain typhoid symptoms, and whose pulse was 112 

 in the minute, the urine was of an orange-red colour, and on 

 the addition of a drop of nitric acid, deposited a sediment of 

 uric acid ; it also contained a little albumen. The quantity of 

 urine in twenty-four hours was 17 ounces, the specific gravity 

 1021, and in 1000 parts there were thirty-four of solid residue. 

 In a man aged 23 years, who had sub-acute pleuritis, whose skin 

 was slightly jaundiced, in whom there was slight anasarca of the 

 lower extremities, (it being a case in which peritonitis was also 

 suspected,) and who was much weakened by the free application 

 of leeches, the urine was of a deep orange-colour and clear; 

 on the addition of nitric acid it deposited an abundant sediment. 

 In the course of twenty-four hours there were 26 ounces of 

 urine passed, of specific gravity 1014-2. 

 1000 parts of urine contained : 



Water .... 976-5 



Solid residue .... 23-5 



Urea . . . .6-1 



Uric acid . . . .0-6 



Fixed salts . . . .6-4 



Organic matters . . . 10-2 



Becquerel attributes the small amount of urea in this case 

 to the debilitated state of the patient. 



He found the mean specific gravity of the urine in seventeen 

 cases of pleuritis to be 1021 '8; in those cases in which there was 

 a spontaneous sediment, it was 1024-8; and in those in which a 

 sediment was produced by the addition of nitric acid, it was 

 1022*7. Albumen was present in three out of the seventeen 

 cases. The amount of mucus was frequently increased, espe- 

 cially in the urine of women, but pus could never be detected. 



Urine, which before the crisis is of a reddish colour, at that 

 period deposits copious sediments. 



[Zimmermann observed fibrin in the urine of a patient with 

 pleuritis, from the third to the fifth day. The urine was of a 

 dark yellow colour, and very frothy.] 



Pleuropneumonia. 



I have had an opportunity of observing a case in which urine 

 of a very peculiar nature was emitted during pleuropneumonia.
