Castor, a substance somewhat resembling musk, secreted by the beaver. It is of the consistency of honey, and has a strong, penetrating, fetid, and volatile odor, which is lost when the substance is dried and hardened. It is used to some extent in medicine as an antispasmodic and stimulant, and is thought to act especially upon the nervous system. It was known and recommended by Pliny and Dioscorides, but it has not a high reputation among modern practitioners; and as it is often largely adulterated, there will be little cause for regret should its use be discontinued. The article considered the best is obtained from Russia. The American beaver produces an inferior quality. Benzoic acid is recognized among the numerous organic compounds of which this substance consists.

Castor River

Castor River, a stream of S. E. Missouri, which rises in St. Francois co., flows S., communicates by several arms with a group of small lakes in Stoddard co., and afterward unites with the Whitewater river. The stream thus formed, which is sometimes called the Castor, but more frequently the Whitewater, flows through a low swampy region, in which most of the streams spread themselves over a large surface and form extensive marshes or lakes. It receives the outlet of Lake Pemisco, and finally discharges itself into Big lake.
