Stronger Ether

Officinal Æther Fortior. Take 3 pints cach of ether and water; shake them thoroughly together in a bottle; and, when the water has subsided, separate the ether from it, and agitate it well with 1 troy ounce each of chloride of calcium and lime, both in fine powder. After standing for 24 hours, decant the ether into a retort, with a Liebig's condenser, connected with a receiver surrounded by ice-cold water, and distill 1+ pints stronger ether, which should be of a specific gravity not exceeding .728.
