Fat . . . . 0-84 



Fixed salts (almost exclusively chloride of sodium > 44-00 



Not a trace of urea or of bile-pigment could be detected. 

 The fat was perfectly saponifiable and contained no cholesterin. 

 In addition to the enormous amount of chloride of sodium in 

 the effusion, it was abundant in the urine (see page 312), and 

 the sweat was so saturated with it that it crystallized in minute 

 glittering particles on the skin. 



In a case of Bright' s disease, in which the walls of the 

 abdomen were punctured, a fluid with an alkaline reaction 

 and specific gravity 1007'5 was obtained. It was analysed by 

 Heller, and found to contain : 



Water .... 980-640 



Solid constituents . . . 19-360 



Albumen 8-121

I made an analysis of the dropsical fluid obtained by 

 puncturing the abdomen of a young man in whom the sub- 

 sequent autopsy revealed suppuration of both kidneys. Urea 

 was present in this fluid, which was of a faintly yellow 

 colour, strongly alkaline, and threw down flocculi of albumen 

 on boiling.
