APPENDIX. 529 



a. In the case noticed in p. 515, of the man aged 38 

 years, the urinary secretion was much diminished. The urine 

 was turbid, of a dark yellow colour, very acid, of specific gravity 

 1017, and deposited a slight, finely flocculent sediment con- 

 sisting of albuminous fungi, pavement epithelium, the peculiar 

 cylindrical forms observed in Brighfs disease, mucus-corpus- 

 cles, and a tolerably large number of blood- corpuscles. 



On the addition of nitric acid, albumen with a violet tint 

 was precipitated ; hence the urine contained a large amount 

 of uroxanthin. 1 



In 1000 parts there were contained : 



Water . . . 948-0 



Solid constituents . . 52-0 



Urea ... 6-1 

 Uric acid . . .no trace 



Fixed salts ... 3-6 



Extractive matters and uroxanthin 23-9 



Albumen with some haematoglobulin 18'4 



The greater part of the salts consisted of sulphate of potash ; 

 only slight quantities of chloride of sodium and phosphate of 

 soda were present, and after the removal of the albumen not a 

 trace of earthy phosphates could be detected. 



No hippuric acid could be obtained from the urine, and as 

 uric acid was likewise absent, the acidity (which in this case 

 was very marked) could not be dependent on these acids. 

 Heller concludes from various observations that the acid re- 

 action is dependent on the presence of the uroxanthin. 



A week afterwards the urine was again analysed. The se- 

 cretion was still diminished, was very turbid, of a pale reddish 

 colour, and formed a flocculent reddish sediment. The specific 

 gravity was 1010, the reaction acid, and the composition of the 

 fluid nearly the same as when previously examined. 



At the expiration of another week, and just before the 

 patient's death, the secretion continued diminished, and the 

 urine rapidly became putrid. The specific gravity was 1011, 

 urea was present in very small quantity, and the sediment 

 contained much pus ; in other points the urine remained the 

 same as before. 



b. The patient was a man aged 40 years, with considerable 

 oedema of the whole body.
