Aqua Camphor & is directed to be made by enclosing the camphor in muslin, 
tying this to the stopper of the jar containing the water, invertiDg the jar, and 
allowing it to stand so for at least two days. All the other waters are to be 
prepared by distillation, but Aqua Menth. Pip. and Viridis are wisely ordered to 
be drawn from the oil,—a drachm and a half of English oil to the gallon. All 
the others are made from the raw materials—also a judicious direction. In Aq. 
Lauro - Cerasi the colouring-matter is omitted. 
Confectio Piperis is a very different preparation from our old Ward’s Paste, 
being now ordered without the Sweet Fennel (which gave it its distinctive fla¬ 
vour), liquorice, and sugar, and having a much larger proportion of honey, this 
being as three to one of the powders. This alteration will at least make it 
keep better than the old. 
Decoct. Scoparii is to be made without the juniper. 
Emplastrum Belladonnas is one-half stronger, being now composed of equal 
proportions of extract and plaster. This is the same strength as the London 
formula ; but instead of plain soap-plaster as there, we have now soap and resin 
plasters, equal parts, which is doubtless an advantage. The new form of Empl. 
Ccilefciciens is a great improvement. It is now prepared from a watery infusion 
of the flies, and forms a homogeneous plaster, which at once commends itself. 
Liquid Extracts are a new introduction, in which the solvent is water alone, 
with rectified spirit added merely for preservation. In this category we have 
Ext. Belce Liq., Ext. Cinchonce Flav. Liq., Ext. Ergotce Liq., Ext. Opii Liq., 
Ext. Pareirce Liq., Ext. Sarsce Liq., and we must hope to see many more articles 
added to it. It would form a most convenient and useful class of preparations, 
and probably supersede concentrated infusions. The principle in the case of the 
Bael, Ergot, and Pareira is to make a pound of the extract represent a pound 
of the drug operated on, and surely it would have been well to carry it out with 
the Cinchona and Sarsa also. An Extract of Cinchona of this strength would 
have the double advantage of being more reasonable in price, and of being taken 
in a more manageable dose. The process for the Ergot is worthy of remark. 
The bruised Ergot, before maceration, is to be percolated with Ether, which dis¬ 
solves and washes away the poisonous oil without affecting the medicinal prin¬ 
ciple, the Ether itself having been washed to remove any alcohol, which, if pre¬ 
sent, might dissolve some of the active principle as well. Ext. Opii Liquidum is 
from the solid extract, one part to. twenty, which, I suppose, is about half the 
strength of Battley’s Solution. 
Felfiovinicm Purificatum. It is a comfort to find a formula for purifying by 
means of rectified spirit the nasty ox-bile. 
Jufis. Aurantii is to be made without the cloves and lemon. Inf. Calumbx is 
much stronger, being half an ounce to ten ounces, which seems the typical standard 
of strength, in the infusions. Inf us. Cliiratx and Inf as. Casparix are directed to 
be mad^ with water at 120°, the first being for half an hour, and the latter for 
two hours. Inf Digitalis is only half the strength it used to be, and wants the 
spirit ;of. cinnamon. The Edinburgh formula for Inf is. Gentianx Comp, is 
adopted. Our southern friends, in forming the acquaintance, must not forget 
that one-fourth part of it is proof-spirit. Inf Quassias has double the quassia, 
and, js made by infusing in cold water for half an hour. The change to cold 
water is for the better, forming a more elegant infusion, which has not the harsh 
taste acquired in the hot process; but surely there is a mistake about the time. 
Inf. Rhci is half the former strength, and without the cinnamon. Inf us. Rosas 
has the sugar omiftcd. The time of infusing is in most instances much short¬ 
ened, and; properly so. 
Linimentum Aconiti is meant to supersede for external use Fleming’s Tincture, 
and has been constituted a liniment to distinguish it from the tincture, which 
is now much weaker, for convenience of internal administration ; but surely this
