2c. SOLUBILITY IN ETHER. 



More of the alkaloids and bitter principles (amaroids) are soluble than 

 insoluble in ether ; the first two lists at foot give substances of these 

 classes that are insoluble or difficultly soluble. With regai'd to gluco- 

 sides, however, the reverse is the case ; in fact gluco«ides are almost 

 invariably insoluble in ether; the third list below gives exceptions to 

 this rule.
