chewing separate into fibres. The former pulverizes more easily. 
than tue latter, and looks, when powdered, of a light brownish 
coleur, resembiing that of cinnamoa, or somewhat paler. It hasa 
slight smell, approaching as it were to mustiness, yet so much of the. 
aromatic kind as not to be disagreeable. Its taste is considerably 
bitter, astringent, very durable in the mouth, and accompanied with 
some degree of aromatic warith, but not sufficient to prevent its 
being ungratetul.’’ * 
Besides this bark, that of several other species of Cinchona have 
been recommended for medical use by different authors, especially 
the cortex peruvianus ruber, or red bark; also that of the cinchona 
caribeea, or the Jamaica bark; that of cinchona floribunda produced 
at St. Lucie; and that of two.or three other species discovered at , 
Santa Fé. The first of these “ is in much larger and thicker pieces.

much stronger than the common officinal sort, An infusion in cold 
water is intensely bitter, more so than the strongest decoction of 
common bark. Its astringency isin an equal dégree greater than 
that of the infusion of common bark, as is shewn by the addition of 
martial vitriol. The spirituous tincture of the red bark is also pro- 
Pesonally stronger than that of the pale. The quantity of matter
