Acidum acetosufn, acetous acid, Lond. 
Take of verdigris, in coarse powde r, two 
pounds ; dry it perfectly in a bath of water 
saturated with sea salt. Then distil in a 
sand-bath, and distil the liquor a second 
time. Its specific gravity is as 1050 to 
1000. 
Acidum benzoicum,. benzoic acid, Ed. 
Flores benzoes, Lond. 
Take of benzoin, in powder, any quantity. 
Place it in an- earthen pot, to the mouth 
of which has been adapted a paper cone ; 
apply a gentle fire, that the acid may be 
sublimed : if it is contaminated with oil, 
it is to be purified by solution in hot water 
and crystallization, or, as the Ph. Lond. 
directs, by mixing it with white clay, and 
again subliming. 
Acidum muriaticum, muriatic acid, Ed. 
Acid, muriat. Load. 
Take of muriat of soda two pounds ; sulphu- 
ric acid sixteen ounces ; water one pound. 
First expose the muriat of soda in a pot to 
a red heat for a short time ; when cold put 
it into a retort. Then pour the acid mix- 
ed with the water and cold on the muriat 
of soda. Distil from a sand-bath, with a 
gentle heat, as long as acid comes over. 
Its specific gravity is as 1170 to 1000. 
Acidum nitrosum, nitrous acid, Ed. and 
Load. 
Take of pure nitrat of potass powdered two 
pounds; sulphuric acid sixteen ounces; 
the nitrat of potass being put into a glass 
retort, pour upon it the sulphuric acid, 
and distil from a sand-bath, with a fire gra- 
dually raised, until the iron pot is of an ob- 
scure red heat. Its specific gravity is 1550 
to 1000. 
Acidum nitrosum dilutum, diluted nitrous 
acid, Ed. and Lond. 
Take of nitrous ackl, water, equal weights.* 
Mix them, avoiding the noxious vapours. 
Acidum nitricum, nitric acid. 
Take of nitrous acid any quantity ; put it into 
a retort; and having adapted a receiver, 
apply a very gentle heat, until the reddest 
part shall have passed over, and the acid 
remaining in the retort shall have become 
nitric. 
Spiritus jetheris nitrosi, spirit of nitrous 
ether, Ed. and Lond. 
l ake of alcohol three pounds; nitrous acid one 
pound ; pour the alcohol into a large phial, 
placed in a vessel filled with cold water, 
and add the acid gradually with constant 
agitation. Close lightly the phial, and set 
it aside for seven clays in a cool place ; 
then distil the liquor with the heat of boil- 
ing water into a receiver cooled with water 
or snow, as long as any spirit shall pass 
over. 
Dose from thirty to fifty drops. 
Acidum sulphuricum dilutum, diluted sul- 
phuric acid, Ed. Acid vitriolicum dilut.

Vol. IP. 
vessel ; then add cinnamon an ounce and 
a half; ginger one ounce. Digest again 
in a closed vsssel for six days, and filtre 
through paper with a glass funnel.

iEther sulphuricus, sulphuric ether, Ed. 
T.lh. vitrioliicus, Lond. 
Take of sulphuric acid, alcohol, of each thir- 
ty-two ounces; pour the alcohol into a 
glass retort, capable of bearing a sudden 
heat ; then pour on the acid in a continued 
stream. Mix gradually with frequent and 
gentleagitation; then hnmediatelydistii from 
a sand-bath, heated previously, into a re- 
ceiver kept cool by water or snow. The 
five is to be so regulated, that the liquor 
maybe made to boil as soon as possible, 
and continue to boil until sixteen ounces 
have distilled over ; then remove the re- 
tort from the sand. To the distilled liquor 
add two drachms of potass ; then again 
distil from a high-necked retort, with a very 
gentle heat, into a receiver preserved cool, 
until ten ounces have come over. If after 
the first distillation sixteen ounces of alco- 
hol are added to the acid remaining in the re- 
tort, and the distillation is repeated, ether 
will again be produced ; and this process 
may be repeated more than once. 
Dose from thirty to sixty drops. • 
Tiber sulphuricus cum alcohole, sulphuric 
ether with alcohol. 
Take of sulphuric ether- one part; alcohol 
two parts. Mix them. 
1 he London college order a compound 
spirit (sp. a'theris vitriolici comp.) to be pre- 
pared by mixing two pounds of unrectiiied 
ether with three drachms of oil of wine. 
iEther sulphuricus cum alcohole aromati- 
cus, aromatic sulphuric ether with alcohol. 
1 his is made from the same materials and in 
the same manner with the compound tinc- 
ture of cinnamon, unless that sulphuric 
ether with alcohol is employed instead of 
diluted alcohol. 
These are useless preparations. 
Carbonas ammonia 1 , carbonat of ammonia, 
Ed. Ammonia preparata, Lond. 
Take of muriat of ammonia one pound ; car- 
bonat of lime, vulgarly called chalk, dried, 
two pounds. Being each separately pow- 
dered, mix them, and sublime from a re- 
tort into a receiver kept cold. 
Dose from five gr. ins to a scruple. 
Aqua carbonatis ammonia?, water of car- 
bonat of ammonia, Ed. Aq. ammonia?, Lond. 
Take ot muriat of ammonia, carbonat of 
potass, ot each sixteen ounces ; water two 
pounds, T o the salts mixed and put into

Liquor volatilis, sal, et oleum cornu cervi, 
volatile liquor, salt, and oil of hartshorn, 
Lond. 
Lake of hartshorn ten pounds; distil, gra-

Aqua ammonia?, water of ammonia, Ed 
Aqua ammonia? pane, Lond. 
l ake of muriat of ammonia sixteen ounces ; 
lime fresh-prepared two pounds ; water six 
pounds. To one pound of water, in an 
iron or an earthen vessel, add the lime 
broken down, and close the vessel tor 
twenty-four hours, until the lime falls into 
powder, which is to be put into a retort. 
To this add the muriat of ammonia dis- 
solved m five pounds of water, and, shut- 
ting the mouth of the retort, mix them 
with agitation. Lastly, distil with such a 
moderate heat, that the operator can easily 
apply his hand to the retort into a receiver 
kept cold, until twenty ounces have distil- 
led over. In this process the vessels are to 
be so luted, as that the penetrating vapours 
may be effectually confined. 
Dose about twenty drops internally ; 
outwardly it is “used as a rubefacient.

hol, Ed. Sp. ammonias, Lond. 
I ake of diluted alcohol four pounds ; muriat

tic ammoniated alcohol, Ed. Sp. amiii. 
comp. Lond. 
Take of spirit of ammonia eight ounces ; 
volatile oil of rosemary a drachm and a 
half; volatile oil of lemon one drachm.

Succinated spirit of ammonia. 
Take of alcohol one ounce; water of pure 
ammonia four ounces; rectified oil of am- 
ber one scruple ; soap ten grains. Digest 
the soap and the oil of amber in the a?co- 
liol until they are dissolved ; then add the 
water of pure ammonia, and mix by a« Ra- 
tion. = 
This has been named eau tie luce. 
Carbonas potassae, carbonat of potass, Ed. 
Kali praparatum, Lond. 
Let impure carbonat of potass (pearl-ashes) 
be put into a crucible, and brought to a 
red heat, that the oily impurities, if there 
are any present, may be burnt out ; then 
rubbing the carbonat with an equal \veipln 
of water, let them be well mixed bv anua- 
tion. The liquor, after the impurities inn e 
subsided, being poured off into a clean iron 
pot, is to be boiled to dryness; towards 
the end of the boiling (he sail is to be kept 
constantly stirred, lest any adhere to the- 
vessel. 
In the London college this preparation 
is better ordered by dissolving* the pearl, 
ashes, and evaporating the solution till a p, l 
licle appears on the surface ; then immediately 
setting it aside, previous to further evapora-
