The greater number of pharmacopoeiasdirect the lime of commerce to be employed.Such are Dubl. ; Edinb. ; Amer. ; Amst. ;Ant. ; Austr. ; Batav. ; Bavar. ;Belg. ; Bruns.; Dan.; Mil. Copen.;Gall. ; Fenn. ; Form. Hop. Fr. ; Fuld. ;Genev.; Hamb.; Hann.; Hass. ; Lipp.;Olden.; Lusit. ; Pol.; Cast. Borus.;Borus. ; Ross.; Sax.; Sukc. ; Herbip. ;Wurceb. ; Coxe ; and Spielmann.

Lond. ; Brugnatelli ; Swediaur ;and Van Mons, direct it to be prepared bythe apothecary.

Batav. ; Gall. ; Fenn. ; and Fuld.allow either the purchased or preparedlime to be used.

The following is the mode of preparing it :

R. White Marble, bruised,

one pound.

Calcine it in a crucible, with a vi-olent heat, for an hour, or till car-bonic acid ceases to be extricated onthe addition of acetic acid. Thenlet it cool, and enclose it in a wellstopped vessel. (Lond.)

Gall. ; Batav. ; Brugnatelli ; Swe-diaur ; and Van Mons give the sameprocess.

Lond. ; Batav. ; Gall. ; and Fuld.

direct it also to be prepared from oyster-shells in the same manner.

Gall, observes that the lime obtainedby the calcination of oyster shells or of eggshells is not pure ; and that it containsphosphate of lime with phosphate of mag-nesia. Fine white marble should thereforealways be preferred.

It may be proper to give here the for-mula for Croll's Anti-febrile Specific, Spe-cijicum anti-febrile Crollii, Wirtem. ; Itis lime in nearly a pure state.

R. Lake Muscle Shells, any quantity.

Macerate them in strong vinegar to cleanthem well ; then wash them in spring wa-ter and dry them. Reduce them to a finepowder, and calcine with a strong heat.

This was administered in the dose offrom a scruple to half a dram, in intermit-tent fevers, before the access ; as much forthe purpose of absorbing acids in the primeeviae, as to excite the secretions of the kid-nies and skin. But it has been observedto induce cardialgía when given in strongdoses, which is not at all surprising.

hydrate of lime. — slaked lime.

Hydras Calcaría, Calx eitincta.(Bavar.)

R. Pure Lime, one part.

Water, one half part.

Pour the water gradually upon the lime ;

and when the mass is cold, enclose it in a

bottle.
