PERUVIAN BARK. 
Saunders to conclude, that the Large Red 
Bark brought to London in the year 1779, 
was of the same kind as that used by Syden- 
ham and Morton ; as it answers to the descrip- 
tion of the Bark used in their time, which is 
given by Dale and other writers on the ma- 
teria medica, who were their contemporaries. 
Dr. Saunders savs, that it is not only stronger 
and more resinous, but likewise more effica- 
cious, and certain in it's effects, than the Com- 
mon Bark ; and, that it has cured many agues, 
after the other had failed. 
There is another species of Cinchona, 
which has been discovered in the West India 
Islands ; and which has been described by Dr. 
Wright, in the Philosophical Transactions, 
under the title of Cinchona Jamaicensis. It is 
called, in Jamaica, the Sea-Side Beech, and 
grows to forty feet in height. 
The Pale and the Red Barks are chiefly used 
in this country ; though, in addition to these, 
another species has been lately introduced, 
called the Yellow Bark, the virtues of which 
are described in a Treatise by Dr. Relph.
