presenting a very smooth surface. Its fracture is very ee 
with long fibres extending into both the pieces separated, 
and whichare more distinct in the inner part; it is also less 
compact than the former, particularly im the in terior. When it 
is pounded, a very fine, fibrous, and subtle powder separates 
from it, which penetrates the pores of the skin almost in the 
same manner as the fibres of the Dolichas pruriens. Under 
the pestle it yields a faintly-yellow powder, abounding in small 
fibfes.* The genuine Calisaya is much esteemed; it is admi- 
nistered alone, and produces good effects. Practitioners say that 
mixed with the Quinquina in the proportion of one part to three, 
it produces much more certain results, In this manner it was 
latterly employed in the royal pharmacy.

inferior in quality to the Calisayas of Quito and La Paz. It 
occurs in commerce mixed with the barks of the orange-co- 
loured Quinquina, and of two other yellow Quinquinas of the 
sary to leave all the intermediate stripes, which in the sequel of the operation are deprived 
of a part of their epidermis towards the*edges, By these means a considerable portion of the 
bark remains attached to the branch, and is rejected as useless, This loss is the more to be re- 
_ gretted, because it is almost certain that the ae has no influence on the febrifuge qua- 
lities of the’ ‘Quinguina. 
The epidermis of the Calisaya is ‘thick, rough, and of a reddish brown covered with 
whitish lichens; its fracture is clear and resinous ; it is easily reducible to powder, which is 
of a deep red, presenting no fibres and having no taste. The facility with which it separates 
the rest of the bark will allow an exact analysis of it to be made. It is little esteemed, 
and for this reason the barks are stripped of it, 
very pliant, and the fibres resulting en its sapesitien vein 8 bbrfect
