FERRUM— IRON.

one pound of pulverized hydrochlorate ofammonia, and -the mixture to be sublimedonce in a sand-bath, with a heat at first mo-derate, but gradually augmented till the bot-tom of the phial is on the point of becomingred.

R. Pure Iron Filings, one ounce.

Hydrochloric Acid, a sufficient quantity

to dissolve the metal. Add to the solution

Hydrochlorate of Ammonia,

twelve ounces.

Dry the mixture over a moderate fire,pulverize and sublime the residuum.(Dan. ; Lipp.)

R. Hydrochlorate of Iron, one part.

Hydrochlorate of Ammonia,

twelve parts.

Mix and sublime them in a glass phial :pulverize the product. (Ant.)

Eelg. winch gives the same proportions,directs the mixture to be dissolved in asufficient quantity of water, and the solu-tion to be evaporated to dryness. — VanMons proposes to dissolve one part ofhydrochlorate of iron, and sixteen parts ofhydrochlorate of ammonia in thirty-two ofwater, and to leave the solution to sponta-neous evaporation in a sand-bath scarcelywarm, that crystals may form. — Ferr. pre-scribes nine ounces of hydrochlorate of am-monia and three ounces of hydrochlorate ofiron.

Other variations are also met with :Hans. ; Lipp. ; and Sax. prescribe onepart of hydrochlorate of iron, sixteen partsof hydrochlorate of ammonia, a sufficientquantity of distilled water to dissolve them,and the evaporation of the liquor to dryness.Niemann — one part of hydrochlorate ofiron, twelve parts of hydrochlorate of am-monia, a sufficient quantity of water to effecttheir solution, and evaporation to dryness.Bata v. — the same proportions and the sameprocess, with the difference of requiring theproduct to be sublimed. — Fenn. ; and Sijec."-one part of hydrochlorate of iron, sixparts of hydrochlorate of ammonia, a suffi-cient quantity of water to dissolve them, andevaporation to dryness. — Swediaur — onepart of hydrochlorate of iron, four parts ofhydrochlorate of ammonia, a sufficientquantity of water to dissolve them, and sub-limation or evaporation to dryness. — Britg-natelli — one part of hydrochlorate of iron,two parts of hydrochlorate of ammonia, asufficient quantity of water, and evaporationto dryness.R. Hydrochlorate of Iron calcined

to whiteness, one part.

Hydrochlorate of Ammonia, pureand dried with heat, twelve parts.

Mix with rapid trituration, put them intoa phial, and sublime quickly with the heatof a sand-bath. (Van Mons)

R. Hydrochlorate of Ammonia,

eight parts.Distilled water, a sufficient quantity.Dissolve and add

Pure Iron filings, half an ounce.

Effect the solution with the aid of heat,filter the liquor, and evaporate it to dryness.(Van Mons)

Van Mons proposes also to mix togetherone part of iron filings, eight parts of hy-drochlorate of ammonia, and two of hotwater ; to leave the mixture in repose foreight hours ; to add then twelve parts ofwater, to boil the liquor, and finally to filterand set it aside to crystallize.R. Iron Filings, one part.

Pulverized Hydrochlorate of

Ammonia, sixteen parts.

Sublime the mixture in a sand bath witha gradually augmented heat, and pulverizethe product. (Ferr. ; Lvjsit. ; Sax.)

Herbip. prescribes one part of filings,and two parts of hydrochlorate. — Hass. —■four ounces of filings, and one pound ofhydrochlorate. — Spielmann — one ounceand a half of filings, and sixteen ounces ofhydrochlorate. — Sard. — four ounces offilings, and half a pound of hydrochlorate. —Pal at. ; and Wirtem. — four ounces offilings, and one pound and a half of salt. —Brugnatelli — two ounces of filings, andone pound of hydrochlorate. — Van Mons —one pound of steel filings, and fifteen poundsof hydrochlorate.R. Hydrochlorate of Ammonia,

five parts.Chloruret of Sodium,

five parts and a half.

Sulphate of Iron, six parts and a half.

Dry and pulverize the three salts, mix

the powders, dry them again, and finally

sublime. (Van Mons)

R. Sulphate of Iron, 1 of h

Hydrochlorate of Am- y , '

I an equal part.

a sufficient quantityto dissolve them. When the solution is cold,add to it

Solution of Ammonia,

a sufficient quantity ;or, till it ceases to produce any precipitate ;wash this, and evaporate the united liquorsto dryness. (Caoet de Gassicourt ;Van Mons)

R. Native Phosphate of Iron, one part.Muriate of Ammonia, four parts.

Pulverize, mix, and sublime with a strongheat, (Van Mons)

It is excitant, corroborant, and tonic, andhas been also classed among the resolvents,diuretics, anthelmintics, and emmena-gogues. It is administered in obstinate in-termittents, in those particularly which are
