SAPPHIRINE WATER, in the materia medica, also called blue eye-water, is thus prepared: Pour a pint of lime-water, made strong and fresh, into a copper-veffel, add to it a dram of crude sal armoniac, and throw in some filings or small pieces of copper, and let it stand till it has acquired a beautiful colour.
This is used as an eye-water; as also to deterge old ulcers; and sometimes it is mixed with other things in injections in gonorrhoeas.
