404 
differ in strength. Dose, as a diaphoretic, of 
the former about 40, of the latter 20, drops. 
Vinum antimonii, antimonial wine, Pii. L. 
l ake of vitrified antimony powdered one 
ounce; Spanish white wine one pound and 
a half. Digest for twelve days with fre- 
cpient agitation, and fi It re through paper. 
1'lois is a preparation of very uncertain 
strength. 
Antimonium calcinatum, calcined anti- 
mony, Ph. L. White oxide of antimony. 
Take- of antimony in powder eight ounces; 
powdered nitre two pounds. Mix them, 
and throw the mixture gradually into a 
red-hot crucible. Bum the matter which 
remains after the deflagration for half an 
hour, and when cold rub it to powder; 
then wash it with distilled water. 
This has been employed as a substitute 
for James’s powder. Its dose is how ever un- 
certain. 
Ammoniaretum cnpri, ammoniaret of cop- 
per -..cuprum ammoniacum). 
1 ake of pure sulphat of copper tw r o parts ; 
carbouat of ammonia three parts. Rub 
them assiduously in a glass mortar until all 
effervescence is over, and they form into a 
violet-coloured mass, which being wrapped 
in bibulous paper, is to be dried first on a 
chalkstone and afterwards by means of a 
gentle heat. The ammoniaret is to be 
preserved in a giass phial well stopped. 
Dose half a grain at first, gradually in- 
creased to three or more grains. 
Solutio sulphatis cnpri compos! ta, com- 
pound solution of sulphat of copper. 
Take of sulphat of copper and sulphat of alu- 
men, of each three ounces; water two 
pounds ; sulphuric acid one ounce and a 
half. Boil the sulphats in water, that they 
may dissolve ; then to the liquor filtred 
through water add the acid. 
Aqua cupri ammoniati, w'ater of ammoni- 
ated copper, Loud. 
Take of sal ammoniac (muriat of ammonia) 
one drachm ; lime-water one pound. Al- 
low them to remain in a copper vessel un- 
til the ammonia is saturated with copper. 
This is employed as a gentle escbarotic. 
Carbonas ferri praecipitatus, precipitated 
carbonat of iron. 
Take of sulphat of iron four ounces ; carbo- 
nat of soda five ounces; water ten pounds. 
Dissolve the sulphat in the water ; then 
add the carbonat, previously dissolved in a 
quantity of water, as much as necessary, 
and mix them well together. Let the car- 
bonat of iron which is precipitated be 
washed with warm water and afterwards 
dried. 
Dr. Griffiths’s preparation of steel is an 
extemporaneous formula similar to the above. 
Sulphas ferri, sulphat of iron, Ed. Ferrum 
vitriolatum, Loud. 
Take of purified filings of iron six ounces ; 
sulphuric acid eight ounces ; water two 
pounds. and a half. Mix them; and the 
effervescence being finished, digest for a 
short time in a sand-bath. Then strain 
the liquor through paper, and after proper 
evaporation put it on one side in order to 
form crystals. 
This is perhaps the most active and use- 
ful of the chalybeates. Dose from one to 
four or five grains. 
PHARMACY, 
Sulphas ferri exsiccatus, dried sulphat of j 
iron. 
Take of sulphat of iron any quantity: heat it j 
in an earthen vessel unglazed on a gentle ; 
fire until it becomes white and perfectly 
dry. 
Oxidum ferri rubrum, red oxide of iron. 
Let dried sulphat of iron be exposed to a vio- 
lent heat until it is converted into a red 
matter. 
Tinctura muriatis ferri, tincture of muriat 
of iron, Ed. Tinctura ferri muriati, Lond. 
l ake o! the purified black oxide of iron pow- 
dered three ou nebs; muriatic acid about j 
ten ounces, or sufficient to dissolve the 
powder. Digest with a gentle heat, and 
the powder being dissolved, add sufficient 
quantity of alcohol to make the w hole li- 
! quor two pounds and a half. 
An active and useful preparation. Dose 
from ten to twenty drops. 
Murias ammonias et ferri, muriat of ammo- 
nia and iron, Ed. Ferrum ammoniacale, 
Lond. 
Take of red oxide of iron washed and again 
dried ; muriat of ammonia, of each equal 
parts. Let them be well mixed, and sub- 
lime. 
'1 his preparation is not much in use. 
Tinctura ferri ammoniacalis, Ph. Lond. 
Take of ammoniacal iron four ounces; proof 
spirit by measure one pound. Digest and 
strain. 
1 his is a superfluous preparation. 
Ferrum tartarisatum, tartarised iron, Ph. 
Lond. 
l ake of filings of iron one pound ;- crystals 
of tartar powdered two pounds ; distilled 
water one pound. Mix them, and expose 
the mixture to the air in an open glass ves- 
sel for eight days; then rub the matter 
dried by a sand-bath into a very fine pow- 
der. 
Dose from five to ten or fifteen grains. 
Vinum ferri, wine of iron, Ph. Lond. 
Take of iron filings four ounces ; Spanish 
white wine four pounds. Digest for a 
month with frequent agitation, and strain. 
Dose one or two drachms. 
Hydrargyrus purificatus, purified quick- 
silver, Ed. and Lond. 
Take of quicksilver four parts ; filings of iron 
one part. Rub them together, and distil 
from an iron vessel. 
Acetis hydrargyri, acetite of quicksilver, 
Ed. Hydrargyrus acetatus, Lond. 
Take of purified quicksilver three ounces; 
diluted nitrous acid four ounces and a half, 
or a little more than may suffice to dissolve 
the quicksilver; acetite 'of potass three 
ounces; boiling water eight pounds. Mix 
the quicksilver with the diluted nitrous 
acid, and towards the end of the efferves- 
cence digest, if it may be necessary, with 
a gentle heat, until the quicksilver is to- 
tally dissolved ; then dissolve the acetite 
of potass in boiling water, and immediately 
on this solution while hot pour the other, 
mixing them by agitation. Then place 
the mixture on one side that crystals 
may form. These being put into a funnel, 
wash them with cold distilled water; and 
lastly dry them with a very gentle heat. In 
preparing the acetite of quicksilver, it is 
j necessary that all the vessels and the fun- 
j ne’l which are used, are of glass, 
T his lias been employed as an antisypbi- 
litic, in the dose of a grain night and morning, 
Its operation, however, is perhaps not to be 
depended on. 
Murias hydrargyri, muriat of mercury, Ld. 
Hydrargyrus munatus, Lond. 
! Take of purified quicksilver two pounds ; 
sulphuric acid two pounds and a half; mu- 
riat of soda dried four pounds. Boil the 
quicksilver with the sulphuric acid in a 
glass vessel placed on a sand-bath till the 
i matter becomes dry. When cold, mix it 
with the muriat of soda; then sublime it 
in a glass cucurbit, with a heat gradually 
raised. Separate the sublimed matter from 
the scoria?. 
T his (the corrosive sublimate) is the 
most active ot all the mercurial preparations. 
Dose about a fourth of a grain. It is not now 
so much as formerly used in the cure of sy- 
philis. 
Submurias hydrargyri, submuriat of quick- 
silver, Ld. Calomelas, Lond. 
Take of muriat of quicksilver rub- 
bed to powder in a glass mortar four 
ounces; purified quicksilver three ounces. 
Let them in a glass mortar be rubbed to- 
gether, with a very little water, in order to 
guard against the acrid powder which- 
would without tliis precaution arise, until 
the quicksilver is extinguished. Put the 
dried powder into an oblong phial, of which 
it shall occupy one-third, and let it be sub- 
limed in a sand-bath. The sublimation 
being completed, and the phial broken, the 
red powder about the bottom and white 
about the neck of it, are to be both 
rejected, the remaining mass is again to be 
sublimed and rubbed into a fine powder, 
which is lastly to be washed with boiling 
distilled water. 
This of all mercurial preparations is the 
most important in medicine. Its dose, ac- 
cording to the different diseases and circum- 
stances under which it is employed, varies 
; from an eighth of a grain to ten or more 
grains. It ought never to be given in solu- 
tion. 
Submurias hydrargyri pnecipitatus, pre- 
cipitated submuriat of mercury, Ed. Hy- 
drargyrus muriatus mitis, Lond. 
Take of diluted nitrous acid, purified quick- 
silver, of each eight ounces ; muriat of soda 
four ounces and a half ; boiling water eight 
pounds. Mix the quicksilver with the di- 
luted acid, and towards the end of the ef- 
fervescence digest with a gentle heat, fre- 
quently shaking the vessel. It is neces- 
sary that more quicksilver should be mixed 
with the acid than this can dissolve, that 
the solution may be obtained completely 
saturated. Dissolve at the same time the 
muriat of soda in the boiling water while it 
is warm ; pour on it the other solution, and 
quickly mix them together. After the 
precipitation, pour off the saline liquor, 
and wash the submuriat of mercury by 
frequently adding warm water, pouring it 
off after each time of the subsiding of the 
precipitate until it comes off tasteless. 
This preparation does not materially dif- 
fer from the preceding. 
Oxidum hydrargyri cinereum, ash-coloured 
oxide of quicksilver.
