Essences (concentrated infusions) of quassia, cascarilla, chiretta, gentian, etc, may be made as directed for Liquor CalumbAe, P. F. Take 8 times the quantity of ingredients directed in the Pharmacopoeia for one pint of infusion, and infuse them in one pint of boiling water for the time prescribed; strain with strong pressure, and again infuse the ingredients in nearly as much water as the liquor obtained is short of a pint. Strain again with pressure; mix the products, which will measure 18 or 19 oz.; add 2 oz. of rectified spirit, set aside for a few days in a well-closed bottle, and filter. Some substances, as chiretta, senna, calumba, etc, yield their active principles to cold water, which some prefer in these cases; but it is then necessary, before adding the spirit, to place the liquor (in a bottle) in a water-bath, and heat it to 180° F., in order to precipitate any albumen it may contain. When cold, filter and add the spirit. They may also be made by percolation.

Godfrey's Cordial. The active ingredient is opium, and there is a great diversity in the strength of the compound as prepared by different makers. Many accidents have arisen from its too general use as a stupefactive for infants, but we believe its sale is now much less encouraged by druggists than formerly. The following are some of the more usual formulae. 1. Heat together 7 lbs. (avoird.) of treacle, and 8 lbs. of water till united; when nearly cold add the following: rectified spirit 6 fluid ounces, oil of sassafras 40 minims, oil of aniseed 10 drops, laudanum 4 oz. Mix and make up the weight if necessary to 15 lbs. It contains rather more than 9 minims (equal, according to some authorities, to 16 or 18 drops) of laudanum in each fluid ounce.

2. Treacle 3 1/2 lbs., water 6 lbs., spirit of wine 8 fluid ounces, laudanum 4 fluid ounces, oils of aniseed, sassafras, and caraway, of each 1/2 dr. Mix. Contains 12 or 14 minims of laudanum in an ounce.

3. Sliced sassafras 2 oz., opium cut small 1 oz., bruised aniseed 8 oz., boiling water a gallon. Infuse, strain, and make the infusion into a syrup with 14 lbs. of treacle. If the whole of the active principles of the opium are extracted, this is much stronger than the preceding.

4. Make a syrup with 3 lbs. (avoird.) each of treacle and coarse sugar, and water sufficient to make up a gallon. Dissolve 24 drops of oil of sassafras, and 16 of oil of aniseed, in 3 fluid ounces of spirit of wine; add 10 fluid drachms of tincture of opium, and mix the whole with 8 pints, o. m., of the syrup. This is weaker than either of the preceding, containing only 5 minims of laudanum in a fluid ounce, or 1 drop in a drachm.

5. The Philadelphia College of Pharmacy, to prevent the mischief arising from the varying strength of this compound, directs it to be prepared as follows: Dissolve 2 1/2 oz. of carbonate of potash in 26 pints of water, add 16 pints of treacle; heat together over a gentle fire till they simmer, remove the scum, and, when sufficiently cool, add 1/2 oz. of oil of sassafras dissolved in 2 pints of rectified spirit, and 24 fluid ounces of tincture of opium, previously mixed. The old wine measure is here intended. It contains about 16 minims of laudanum, or rather more than 1 grain of opium in each fluid ounce.

6. Sassafras 9 oz., seeds of coriander, caraway, and anise, of each 1 oz.; infuse in 6 pints of water, simmer the mixture till reduced to 4 pints; then add 6 lbs. of treacle, boil the whole for a few minutes, and when cold, add 3 fluid ounces of tincture of opium. Nearly the strength of No. 1. - Dr. Paris.
