ALSTON! A SCHOLARIS. 99 



It possesses strong tonic and antiperiodic properties, and is 

 ardently recommended by many as a substitute for quinine. 



ALSTONIA CONSTRICTA. 



Closely related to this drug is Alstonia Constricta, called the 

 Australian fever-bark. It is occasionally imported from India, and 

 has been sold in London as Bebeeru bark. It contains no alkaloid, 

 according to Holmes of London. The bark is fibrous internally 

 and rough and corky externally, though all of the specimens which 

 it has been my fortune to meet are more delicate and of a lighter 

 color than the bark of Alstonia Scholaris.
