Of the Centuary we have the above species, which is not inferior to the European. It is a beautiful annual plant, growing abundantly in the Middle and Southern States, and every part of it is medicinal, though the flowers possess the most efficacy. It is a pure bitter, with some little aromatic flavor, neither unpleasant to the taste nor offensive to the stomach; and is resorted to by every description of practitioners, regular and irregular, in our intermittent and remittent fevers. Like some other articles, it has an advantage over the Peruvian bark, of being sus-septible of employment in every stage of these diseases. The usual mode of prescribing it is by strong infusion, which is directed to be taken without much limitation.
