MENISPERMACEZ. 61 
Aqueous residue C—The filtered solution was rendered 
_ alkaline with ammonia and agitated with chloroform-ether, 
brownish flocks separated. ‘The separated chloroform-ether 
_ left on spontaneous evaporation a transparent yellowish varnish- 
like residue. In order to purify this extract it was dissolved in 
_ dilute acetic acid in which, with the exception of a few flocks it - 
was wholly soluble. ‘The filtered solution was agitated with 
_ chloroform several times; finally the liquid was rendered 
alkaline and again agitated with chloroform. On separating 
_ and evaporating off the chloroform, a faintly yellowish trans- 
parent residue was left; this residue was practically insoluble 
_ In water : it was easily dissolved by alcohol, and also soluble in 
- ether, but the solutions did not crystallize on slow evaporation, 
_ The alcoholic solution was bitter ; it did not exhibit fluorescence. 
In dilute acids, especially tartaric acid, the extract was - 
soluble, the resulting solutions being bitter. With nitric, 
hydrochloric, sulphuric, acetic, and tartaric acids no crystalline 
compounds could be obtained. From an acid solution alkalies 
ike residue, which also gave all the reactions of an alkaloid, _ 
-and which appeared to be similar to the principle separated _ 
_ from the alkaline solution ; the alkaloid being thus separable _ 
both from an acid and an alkaline solution by chloroform, &e.
