APPENDIX. 531 



In 1000 parts there were contained : 



Water . . . 985-2 



Solid constituents . . 14-8 



Organic matter . . 13-6 



Fixed salts . . 1'2 containing hardly a 



trace of chloride of sodium. 



e. A patient aged 28 years, who first exhibited symptoms 

 of Bright's disease while in the hospital, in consequence of a 

 broken arm from a fall. The spinal cord likewise appeared 

 somewhat injured by the accident. 



The urine was much diminished in quantity, scarcely amount- 

 ing to twelve ounces in the twenty-four hours ; it was of a 

 bluish green (or very deep bottle-green) colour, turbid, and de- 

 posited after a short time a flocculent light-blue sediment. 

 After standing for a longer period, a dark blue sediment was 

 gradually thrown down, while the supernatant fluid was yellow. 



The surface of the urine was covered with a stiff film of 

 uroglaucin, which presented a beautiful copper-like brilliancy 

 when the light fell on it. With refracted light it appeared of 

 a dark-blue colour, and arranged in stellar groups. The sedi- 

 ment, when examined under the microscope, was found to 

 consist of a great quantity of albuminous fungi and minute 

 crystals of ammoniaco-magnesian phosphate, together with 

 groups of uroglaucin, more or less crystalline in structure, 

 and of a magnificent blue colour : a peculiar modification of 

 pavement epithelium was likewise observed, oval or nearly 

 circular, with large nuclei and nucleolar corpuscles, frequently 

 arranged in groups ; and lastly, cylinders with a little pus. 



The reaction of the urine was strongly alkaline, and its 

 specific gravity 1013. 



On the addition of nitric acid the urine became of a clear 

 blue colour, and albumen with a violet tint was precipitated, 

 which on standing became of a darker blue, while the super- 

 natant fluid assumed a yellowish hyacinthine colour. 



Alcohol slowly added, so as to form a layer on the surface, 

 took up an azure colouring matter. On thoroughly mixing 

 the alcohol with the urine, albumen with a beautiful blue tint 

 was precipitated, while the fluid remained of a hyacinthine 

 colour. 



Ammonia communicated a brown colour to the urine.
