Sulphuric Ether is used _externally_ both as a stimulant and a
refrigerant. In the former case its evaporation is prevented by
covering a rag moistened with it with oiled silk, in order to relieve
headache; and in the latter case it is allowed to evaporate, and thus
produce coldness: hence it is applied over scalded surfaces by means
of rags dipped in it.
_As a local application_, it has been found to afford almost instant
relief in earache, when combined with almond oil, and dropped into the
ear.
It is used _internally_ as a stimulant and narcotic in low fevers and
cases of great exhaustion.
_Dose_, from fifteen minims to half a drachm, repeated at short
intervals, as its effects soon pass off. Give in a little camphor
julep, or water.
