_Spirit of Camphor_; vulgo, _Camphorated Spirits_.
This preparation is principally useful as an external application. As an
embrocation to chilblains it is often of essential service; and it has
been found useful when thus applied to parts affected with chronic
rheumatism and paralytic numbness. It is instantly decomposed by water,
which precipitates the camphor. It furnishes an easy mode of forming
camphor mixture extemporaneously, and if a few drops be rubbed with
mucilage, we are thus enabled to form a stronger preparation than by the
ordinary process.
