QUERCÚS.

Its acorns are employed ; they are some-times sweet and good for eating. The cupsare furnished with very small scales, mi-nutely imbricated, and cottony.
The barks of the oaks, especially of theQ. Roiur contain much tannin with an ex-tractive matter. They possess a very de-cided astringency, so that when administeredin a large dose, they irritate the digestiveorgans, and yet, at the same time, do notdetermine a general reaction. They havebeen proposed as a substitute for cinchona,but they seem to be very inferior to it as afebrifuge. — Dose, from a dram to one ounce,of the powder.
As to the acorns, those of them which arebland are used as food : the others, whenroasted, have been recommended as a use-ful excitant in glandular affections, particu-larly in scrofula.
