it is to be diCcootinued, and the bark exf.ibiled by it–

Celf. Afler the fever has been removed, the medicine

is continued for Come time longer, to

and evacuations, unleCs abCuhllely neceffary, abflained

In CymptoOlatic aglles, heé'tic aod puruleot fe vm,

The "inues of Peruvian bark rersde chiefly in a re·

by reélified fpirit. By Ilrong coélion in water, the re–

fin is me!led OUt, and mingled wilh the Waler; which

whilll hot appears tranCpmot, but in cooling grow,

turbid, and depofites great pJrt of the refin to the

botlom. Water elevales in difl.!lation Ihe aromatic

of the bark; pure fpirit brings ol'er nothing.
