A Pound of Cotton-Wool

Bark. A French merchant, M. Delpech, residing at Guayra, in the Caraccas, had stored up a large quantity of fresh cinchona, in apartments which were afterwards required for the reception of some travellers as guests. These apartments contained each eight or ten thousand pounds of bark; and in consequence of its fermentation, the heat was much greater here than in the other parts of the house, rendering the place somewhat disagreeable. One of the beds placed in these rooms, was occupied by a traveller, ill of a malignant fever: after the first day he found himself much better, though he had taken no medicine; in a few days he felt himself quite recovered, without any medical treatment whatsoever. This unexpected success induced M. Delpech to make some other trials: several persons ill of fever, were placed successively in his magazine of cinchona, and they were all speedily cured, simply by the effluvia of the bark.

It happened that a bale of coffee, and some common French brandy, were kept in the same place for some months: one of the brandy bottles happened to be uncorked, and, on examination, was found to possess a slight aromatic taste, to be more tonic, and very superior to common brandy. The coffee was also much altered; when roasted, it was more bitter than common coffee, and left in the mouth a taste similar to that of an infusion of bark.

It is to be observed, that the bark which produced all these effects was fresh; and the question whether that of commerce would produce the same effects can only be answered by ex periment.
