Ether Compound Spirit of Sulphuric Ether is a very useful stimulant, narcotic, and antispasmodic. _Used internally_ in cases of great exhaustion, attended with irritability. _Dose_, from half a drachm to two drachms, in camphor julep. When combined with laudanum, it prevents the nauseating effects of the opium, and acts more beneficially as a narcotic.
