388 THE EXCRETIONS: 



E. Bichloride of mercury produced a light-green precipitate, 

 leaving the supernatant fluid pale, but not decolorizing it. 



It was analysed in the following manner : 



1. 1000 grains of the green fluid left, by careful evapora- 

 tion, a deep olive-green, highly deliquescent extract, weighing 

 100 grains. 



2. This extract, on being immersed in alcohol of '837 formed 

 a mass like birdlime, which could not be mixed with the spirit. 

 Even after long boiling, it appeared hardly to diminish in bulk. 

 The clear tincture being decanted left, however, an extract 

 weighing 30 grains. This residue possessed the yellowish- 

 green colour of faded leaves, an odour of fresh broth and a 

 sweet sub-astringent taste, with a very slight admixture of 

 bitterness. 



3. The alcoholic Extract being carefully incinerated, left 5-5 

 grains of ash, consisting chiefly of chloride of sodium mixed 

 with mere traces of tribasic phosphate of soda (3NaO, POJ. 

 It was alkaline, but did not effervesce with acids. 



4. The portion left undissolved by boiling alcohol yielded to 

 water 13 grains of nearly tasteless matter which, by incinera- 

 tion, left a powerfully alkaline ash weighing 1*75 grains, not 

 effervescing with acids, and consisting nearly exclusively of 

 alkaline tribasic phosphate of soda. 



5. The residue insoluble both in water and alcohol weighed 

 57 grains, and consisted almost entirely of coagulated albumen, 

 dry mucus, and modified blood. It left by incineration one 

 grain only of ash, consisting almost wholly of black-red peroxide 

 of iron.
