from potass being liberated by the re-actionof the oxide of iron on the supertartrate ofpotass. It may be divested of this incon-venience, according to Henri, by satura-ting the excess of alkali by a sufficient ad-dition of tartaric acid.

R. Porphyrized Iron Filings, one part.

Red Tartar, in powder, two parts.

Alcohol (18 degrees),

a sufficient quantityto make a liquid mass (bouillie) ; leave thisin the air for five or six days, at a rather warmtemperature, stirring it from time to time ;then expose it to a heat of 70-80 degrees, stir-ring it frequently with a spatula. When ithas acquired the consistence of thick honey,mix it with another quantity of alcohol of thesame strength : evaporate it, and add againmore alcohol. Continue this process tillthe matter presents a perfectly black appear-ance, and till it has lost all acidity. Thenfinally evaporate it to the consistence of amanageable paste, and make balls of anounce weight each, which are to be slowlydried in a stove. (Bruns. ; Gall. ; Form.Hop. Fr. ; Wirtem. ; Herbip. ; VanMons)

Hisp. prescribes eight ounces of iron,twelve of tartar, and a mixture of equalparts of water and of alcohol.

R. Tartarized Extract of Iron,

four ounces.

Supertartrate of Potass, two ounces.

Mix them intimately in an iron mortar,

reduce the mixture to balls of half an ounce

each, and dry them with a slow heat.

(Lipp.)

R. Iron Filings, two ounces.

Supertartrate of Potass, four ounces.Water, a sufficient quantity

to obtain a soft paste: dry it with a slow heat,constantly stirring it ; pour water upon theresiduum, and dry it in the same manner.Repeat this several times in immediate suc-cession, and finally having reduced it to theconsistence of a thick extract, make it intoballs of an ounce each. (Austr.; Hass.;Piderit)

Bavar. ; Hann. ; Olden. ; Pol. ; Bo-rus. ; and Sax. prescribe one part of filingsand four parts of supertartrate. — Dan. —one of filings and three of the salt.

Chevallier and Idt describe two otherprocesses, one due to Resat and the otherto Rol. The first consists in mixing threeparts of pulverized tartar with two parts ofiron filings, and a sufficient quantity ofwater to make a paste, covering this withwater, and evaporating it to the consistenceof a thin extract, then exposing the mix-ture to the air for several days ; in coveringthe mass again with more water, and eva-porating it to the consistence of pilular ex-tract : finally, in pounding this mass till itpresents a black fracture without a metallicaspect, and in rolling it into balls of anounce or ounce and a half each.

By adding to five parts of the mass pre-pared thus, one part of benzoin and onepart of turpentine, Resat prepares whatare called Molsheim's Balls.

Rol's process is the same as that of Re-sat, but that for the preparation of Mol-sheim's Balls is different. It consists inmixing intimately together two pounds ofthe paste, three ounces each, of powderedmastic and of olibanum, and one ounce ofmyrrh ; in forming of this mass oval balls,which are moulded with a metallic instru-ment, and ornamented with a ribband atone of their ends.

The Globuli Tartari martiales are a mix-ture of tartrate of potass and of iron, ofneutral tartrate of iron, and of iron in excess.

They are excitant, astringent, tonic, re-solvent, and aperitive ; and are adminis-tered in rachitis, chlorosis, leucorrhcea,and, generally, in all asthenic disorders.

Dose, from five to ten grains, to youngpatients ; and from thirty to forty to adults,repeated several times a day. They are alsoemployed externally, in fomentations tosprains and luxations.
