PALE CINCHONA OF BAD QUALITY. 
ART. LXIV. — UPON A PALE CINCHONA OF BAD QUALITY 
FOUND IN COMMERCE. 
This bark is that of the Cinchona ovata of the Flora 
Peruviana, it does not exist generally in commerce, and is 
found but rarely mixed with Loxa Bark. 
It is without doubt the high price of the Cinchonas, which 
has occasioned the introduction into the market of this bad 
quality of bark. Many parcels of it have been already sold, 
and we have been informed that the central Pharmacy has 
been furnished with fifteen or sixteen seroons. 
The bark of the Cinchona ovata, has been examined by 
M. Manzini, pharmacien interne to the Hotel Dieu, who 
has described its characteristics. M. Bouchardat, has made 
an analysis of it, and has obtained from it neither quinia or 
cinchona. A committee of the Academy of Medicine has 
been entrusted with its examination, and at some future pe- 
riod we shall make known the result of their labor. 
This cinchona, as it ought not to be employed for any of 
the pharmaceutical preparations which are employed, either 
powder, wine, syrup, extract or tincture, should be rejected 
by every conscientious pharmacien. According to M. Man- 
zini, it bears in Peru the name of quinquina jean, and is desig- 
nated by the natives by the application of Patte de Canard; 
it is employed to mix with the good cinchonas. 
It has a yellow color, mixed with gray and pale yellow, it 
is very light, its internal surface is of a deep reddish color and 
covered with powder. Its odor is feeble; its taste at first 
a little bitter, soon becomes developed, and is followed 
by a little astringency. The powder is of a pale brown 
cinnamon color. 
The difficulty which exists of recognising the cinchonas, 
leads us to urge the necessity of establishing the practice of 
entrusting their sale to particular individuals, possessed of 
sufficient skill to determine positively the value of each, and who, 
in case of doubt, should make an analysis of a suspected bark.
