Extract a Fluida. — This new class of preparations, embraces three distinct 
kinds, viz : oleo-resins, concentrated syrups, and concentrated tinctures. 
Two of the first, four of the second, and one of the last are adopted. The 
Extractum Piperis Fluidum, is the officinal substitute for oil of black pepper, 
from which it differs in containing more volatile oil. 
Ferrum. — Tincture of Chloride of Iron, is made expeditiously by the aid of 
heat, and Citrate of Iron is introduced. Many prefer the Ammonio- Citrate, as 
being more soluble. For pills or powders, the officinal citrate is to be pre- 
ferred, and when the form of solution, or syrup is often desirable, it will be 
found convenient to keep a concentrated solution oz. per fluid ounce) at 
hand. Solution of Iodide of Iron differs from that of 1840, in the substi- 
tution of 12 ounces of sugar, for 5 fluid ounces of Prepared Honey. It is 
more easily prepared. The Solution of Nitrate of Iron is made by the formu- 
la of the new Dublin Pharmacopoeia, which is nearly that of Mr. Kerr. It is 
an unsatisfactory preparation, and is not permanent as usually made. The 
suggestion to add sugar does not prevent its changing after a length of 
time. Mr. Samuel Simes, Pharmaceutist, of this city, makes a syrup of proto- 
nitrate of iron, of a light greenish color, and thick consistence, which Dr. 
Hays and others use with decided advantage in cases where the sesqui- 
nitrate is indicated. In the test directions to the formula, for Phosphate of 
Iron, the word "insoluble" in the last line, should read " soluble." Iron by 
hydrogen, under the name of Ferri Pulvis has been introduced, and a cor- 
rect process given for its prepartion. 
Glycerina. — Glycerin is directed to be made from the washings of lead 
plaster. Apothecaries should attend to the appended test directions, and 
see that its sp. grav. is correct, and that it is free from lead. 
Infusa. — Infusum Diosmae — now reads, Infusum Buchu. Infusum Cin- 
chonae, has been replaced by separate infusions of Bed and of Yellow Bark; 
and in compound infusion of bark, the Bed bark is specified as the kind to 
be used. Infusion of Cayenne Pepper is new. Infusion of Dandelion is substi- 
tuted for the decoction very properly. Infusion of Ginger is new. 
Magnesia. — Solution of Citrate of Magnesia is among the prepartions. It 
is one of the most popular and valuable of the new articles. 
Mellita. — The process for preparing Honey of Roses has been greatly 
improved, both as to its color, flavor and consistence. 
Mistura. — Mistura GlycyrrhizcE Composita is the officinal name for 
Brown Mixture, so long and favorably known in this city as an expectorant. 
Olea Destillata. — The Oils of Cloves and Cubebs, now among the prepa- 
rations, were formerly in the list. The Oils of Valerian, Copaiba and Tobacco 
are new; the latter is an empyreumatic oil, obtained by distilling dry 
tobacco in a green glass retort, heated to redness by means of a sand bath. 
Pilule. — The consistence of the Pills of Carbonate of Iron has been 
improved by substituting a portion of sugar for honey, and the manipulation 
altered so as to be more correct and explicit. Pills of Iodide of Iron are 
new. They should only be made extemporaneously. The consistence of 
Pills of Sulphate of Quinia is improved by the use of honey.
