OLDENLANDIA CORYMBOSA 141 



Naylor extracted another principle which he found combined 

 with the alkaloid in a soda precipitate of the latter j it is a 

 product of the decomposition of a glucose, the formula of which 

 is C 25 H 49 O r This compound remains insoluble when the alka- 

 loid is treated with ether. Repeated boiling in alcohol renders 

 it colorless. It is bitter, soluble in alcohol and dilute acids ; 

 insoluble in ether and chloroform. Reaction, neutral.
