Phloridine. — This is a new medicine, which is now very highly spoken 
of by French practitioners as a useful adjunct to our cinchona preparations. 
It has been used for some years in Germany, Poland, and France. It is 
extracted from the bark of the roots of the apple-tree and the wild cherry-

the end of six hours deposit the phloridine in the form of a deep-red vel- 
vety-looking matter.

gicales, says, " its efficacy is so decided, that we cannot hesitate to class 
it with the most powerful febrifuges ; and it has this advantage over qui- 
nine, that it never induces gastralgia."
