ret of iron four ounces, muriatic acid eight 
ounces, previously diluted with two pounds 
and a half of water. The sulplmret of iron 
for this purpose is conveniently prepared 
lrom three parts of purified iron filings, 
and one of sublimed sulphur, mixed, and 
exposed in a covered crucible to a mode- 
rate tire until they unite. 
This is principally given in diabetes, in 
the dose of four or live drops. 
Murias baryta;, muriat of barytes. 
Take of sulphat of barytes two pounds ; pow- 
dered charcoal four ounces. Roast the 
sulphat that it may be more easily pow- 
dered line ; then mix the charcoal ; put 
the matter into a crucible, to which adapt 
a cover, and apply a vigorous lire for some 
hours. Put the matter well rubbed into 
six pounds of boiling water, in a closed 
glass or earthen vessel, and mix them bv 
agitation, guarding as much as possible 
against the access of air. Let the vessel 
stand in a water-bath until the undissolved 
matter has subsided ; then pour off the li- 
quor. Pour four pounds of boiling water 
on the residuum, which add to the former 
liquor after agitation and subsidence. AN' hile 
it is still hot (or, if it has cooled, after it 
has been heated), drop into it muriatic acid 
as long as effervescence is occasioned. 
Then strain and evaporate it so as to form 
chrystals. 
Solutio muriatis baryta;, solution of muriat 
of barytes. 
Take of muriat of barytes one part; distilled 
water three parts. Dissolve. 
Dr. Crawford introduced this in scro- 
phulous affections. Dose from live to twenty 
drops. 
Solutio -muriatis calcis, solution of muriat 
of lime. 
Take of pure carbonat of lime (white marble) 
bruised into small pieces nine ounces; mu- 
riatic acid sixteen ounces ; water eight 
ounces. Mix the acid with the water, and 
gradually add the pieces of carbonat of 
lime: the effervescence being over, digest 
for an hour. Pour off the liquor, and eva- 
porate to dryness. Dissolve the residuum 
iu its weight and a half of water, and strain. 
This has been recently introduced as a 
tonic. Dose thirty drops. 
Carbonas magnesias, carbonat of magnesia, 
Ed. Magnesia alba, Loud. 
Take of sulphat of magnesia, carbonat of 
potass, of each equal weights. Let them 
be separately dissolved in twice their 
weight of warm wrter, and either strained 
or olhenvise freed from impurities; then 
mix them, and add eight times their weight 
of boiling water. Boil the liquor a little, 
and stir it during the boiling ; then allow 
it to rest until the heat is in some measure 
diminished; then strain through linen, 
upon which the salt will remain. Let it 
be washed with pure water until it is per- 
fectly tasteless. 
Magnesia, magnesia, Ed. Magnesia usta. 
Load. 
Let carbonat of magnesia be exposed in a 
crucible to a red heat for two hours ; then 
let it be preserved in glass vessels well 
stopped. 
MdaiUica, metallic preparations. 
Nitras afl'genti, nitrat of silver, Ed. Ar- 
gentum nitivatum, Lond. 
Take of the purest silver, extended in plates 
and cut, four ounces; diluted nitrous acid 
eight oumces ; distilled water four ounces. 
Dissolve the silver with a gentle heat in a 
phial, and evaporate the solution to dryness. 
Then put the mass into a large crucible, 
which is to be placed on the lire, at lirst 
gentle, and gradually increased, until the 
mass flows like oil. Then pour it into iron 
pipes, warmed and rubbed with grease. 
Keep it in a glass vessel well stopt. 
A strong, and frequently employed, cau- 
stic. 
Sulphuretum antimonii, prepared or sul- 
phureted antimony, Ed. Antim. pnrpara- 
tum, Lond. 
This is to be prepared in the same manner as 
carbonat or lime. 
Oxidum antimonii cum sulphure vitrifica- 
tum, vitrified sulphureted oxide of antimony, 
Ed. Antim. vitriticatnm, Lond. 
Strew sulphuret of antimony coarsely powder- 
ed like sand on a shallow earthen vessel 
not glazed, and apply to it a moderate tire 
that the sulphuret. of antimony may beslow- 
ly heated ; at the same time stir the powder 
constantly, that it may not run into lumps. 
White vapours arise, smelling like sulphur. 
When these, while the same degree of heat 
is kept up, cea-w*, augment the heat in 
some measure, that vapours may again ex- 
hale. Proceed in this manner until the 
powder, now raised to a red heat, gives out 
no more vapours. This powder being put 
into a crucible, is to be melted with a 
strong lire, until it assumes the appearance 
of fused glass. It is now to be poured 
upon a heated brass plate. 
Oxidum antimonii vitrificatum cum cera, 
vitrified oxide of antimony with wax. 
Take -of yellow wax one pound ; vitrified 
sulphureted oxide of antimony eight parts. 
To the wax melted in an iron vessel, add 
the oxide reduced to powder, and roast 
with a gentle fire for a quarter of an hour, 
constantly stirring with a spatula; then 
pour off the matter, which when cold is to 
be powdered. 
This is an obsolete remedy. 
Oxidum antimonii cum phosphate calcis, 
oxide of antimony with phosphat of lime, lid. 
Pulvis antimonialis, Lond. 
Take of sulphuret of antimony coarsely pow- 
dered, hartshorn shavings, of each equal 
parts. Mix and throw them into a wide 
iron pot red-hot, and keep them constantly 
stirred until they are burnt into a cineri- 
tious-coloured matter, which is to he re- 
moved from the lire, rubbed into a powder, 
and put into a coated crucible. To this 
crucible, lute another inverted, in the bot- 
tom of which is drilled a small hole ; apply 
the fire, which is to be gradually raised to 
a white heat, and kept so for two hours. 
Lastly, rub the matter when cold into a 
very line powder. 
This preparation is nearly the same as 
James’s powder. Dose five or six grains. 
Sulphuretum antimonii pracipitatum, pre- 
cipitated sulphuret of antimony, Ed. Sul- 
phur antimonii pracipilatum, Lond. 
Take of water of potass four pounds ; water 
3 E 2 
thfee pounds ; prepared sulphuret of anti- 
mony two pounds. Boil them in a co- 
vered iron pot on a gentle fire for three 
hours, stirring frequently with an iron spa- 
tula, and adding water occasionally. Strain 
the liquor while hot through h doubled 
linen cloth, and to the strained liquor add 
as much as may be necessary to precipi- 
tate the sulphuret, which carefully wash 
with warm water. 
A precipitate nearly similar to this has 
been much employed on the continent, espe- 
cially under the name of kermes mineral. 
Both the one and the other have been prin- 
cipally used as alterative or diaphoretic. 
Their operation is uncertain. Dose live or 
six grains. 
Oxidum antimonii cum sulphure per fti- 
tratum potassa-, oxide of antimony with sul- 
phur and nitrat of potass, Ed. Crocus anti- 
monii, Lond. 
Take of sulphuret of antimony, nitrat of po- 
tass, of each equal weights. Triturate them 
separately ; and having mixed them well 
together, throw them into a red-hot cru- 
cible. The deflagration being finished, 
separate the reddish matter from the white 
crust, and rub it into powder, which is to 
be frequently washed with warm water un- 
til it becomes tasteless. 
This is used in some of the other prepa- 
rations; but as a medicine it is so uncertain 
in its operation, that it is scarcely employed. 
Antimonium muriatum, muriat of anti- 
mony, Ed. and Lond. 
Take of oxide ot antimony with sulphur, 
nitrat of potass, sulphuric acid, of each one 
pound; dried muriat of soda, two pounds. 
Pour the acid into a retort, adding by de- 
grees the muriat of soda, and the oxide of 
antimony previously mixed. Then distil 
from warm sand. Expose the distilled mat- 
ter for some days to the air, th.it it may 
liquefy; then pour the liquid from the im- 
purities. • 
This preparation is not proper for inter- 
nal administration. 
Tartris antimonii, tartrite of antimony 
(tartar emetic), Ed. Antimonium tartarisa- 
tum, Lond. 
Take ot oxide of antimony with sulphur by 
nitrat of potass three parts ; supertartrito 
of potass four parts ; distilled water thirty- 
two parts. Boil them in a glass vessel lor 
a quarter of an hour; strain the liquor 
through paper, and set it aside that it may 
form crystals. 
The most certain and useful of all anti- 
monial preparations. Dose, as an emetic, 
from one to two or more grains; as a dia- 
phoretic, a quarter of a grain. 
Yi.nutn tartrilis antimonii, wine of tartrite 
of antimony. 
Take of tartrite of antimony twenty-four 
grains; white wine one pound. Mix so as 
to dissolve the tartrite. 
Vinum antimonii tartarisati, Ph. L. Wine 
of tartarised antimony. 
Take. of tartarised antimony two scruples; 
boiling distilled water by measure two 
ounces; Spanish white wine eight ounces. 
Dissolve the tartarised antimony in the 
boiling distilled water, and add the wine. 
The two last preparations materially
