4575. Class No

4575. Class No. 2, of Classified Fluid Extracts. The drugs included under this class should also be in at least No. 60 powder. Ipecacuanha and jalap may be reduced to dust with advantage. The fluid to be used is alcohol having a specific gravity of .835.

May-apple Boot (Podophyllum or Mandrake). Blood Boot (Sanguinaria). American Hellebore (Ver-atrum viride).

Moisten 16 troy ounces of the drug with 6 fluid ounces of the alcohol; displace 3 pints as directed in class 1, reserving the first 1/2 pint of percolate; distill the remainder until reduced to 1/2 pint, and, while hot, mix the distillate with the reserved tincture. After standing 24 hours, filter through paper.

4576. Class No

4576. Class No. 3, of Classified Fluid Extracts. The substances included under this class require to be used in No. 50 powder ; except columbo, No. 40; and squill, on account of its gummy nature, No. 30. The extract of colchicum deposits, by standing, a whitish sediment, which is believed to be in no wise connected with the activity of the preparation; it is recommended to allow this deposit to form before proceeding to filtration. Dilute alcohol is employed for making these extracts.

Moisten 16 troy ounces of the substance with 4 fluid ounces dilute alcohol, percolate 3 pints, as in class 1, reserving the first 12 fluid ounces, evaporate the remainder to 4 fluid ounces by a water-bath at 150° Fahr.; mix with the reserved tincture; and, after 24 hours, filter.

4577. Class No

4577. Class No. 4, of Classified Fluid Extracts. This class consists of saccharine fluid extracts, the sugar being introduced as a preservative agent. A decided advantage is gained by adding the sugar to the extract before the completion of the evaporation ; in some cases it might bo better to add tho sugar previous to any evaporation. The fluid extracts of pipsissewa, bittersweet, pomegranate, pink-root, and sarsaparilla, fully represent the several drugs; and, combined with 3 times their bulk of simiple syrup, afford syrups of the ordinary strength. The menstruum used in these preparations is dilute alcohol; and the drugs are to bo reduced to No. 50 powder, except galls, which should be No. 40.
