Part 57

A very convenient way to form into pencils where no mold need be made is to take a small glass tube, roll a piece of oil paper around the tube, remove the glass tube, crimp the paper tube thus formed on one end and stand it on end or in a bottle, and pour the melted solution in it and leave until cool, then remove the paper.

«Antiseptic Paste.»—Difficulty is often experienced in applying an antiseptic dressing to moist surfaces, such as the lips after operation for harelip. A paste for this purpose is described by its originator, Socin. The composition is: Zinc oxide, 50 parts; zinc chloride, 5 parts; distilled water, 50 parts. The paste is applied to the wound, previously dried by means of a brush or spatula, allowed to dry on, and to remain in place five or six days. It may then be removed and a fresh application made.

Potassium bicarbonate 32.0 grams Sodium benzoate 32.0 grams Sodium borate 8.0 grams Thymol 0.2 gram Eucalyptol 2.0 c. cent. Oil of peppermint 0.2 c. cent. Oil of wintergreen 0.4 c. cent. Tincture of cudbear 15.0 c. cent. Alcohol. 60.0 c. cent. Glycerine 250.0 c. cent. Water, enough to make 1,000.0 c. centimeters

Dissolve the salts in 650 cubic centimeters of water, and the thymol, eucalyptol, and oils in the alcohol. Mix the alcoholic solution with the glycerine and add the aqueous liquid, then the tincture of cudbear, and lastly enough water to make 1,000 cubic centimeters. Allow to stand a few days, then filter, adding a little magnesium carbonate to the filter, if necessary, to get a brilliant filtrate.

«Alkaline Glycerine of Thymol.»—

Sodium bicarbonate 100 grains Sodium biborate 200 grains Sodium benzoate 80 grains Sodium salicylate 40 grains Menthol 2 grains Pumilio pine oil 4 minims Wintergreen oil 2 minims Thymol 4 grains Eucalyptol 12 minims

«Compound Solution of Thymol.»—

Benzoic acid 64 grains Borax 64 grains Boric acid 128 grains Distilled water 6 ounces

Dissolve.

Thymol 20 grains Menthol 6 grains Eucalyptol 4 minims Oil of wintergreen 4 minims Oil of peppermint 2 minims Oil of thyme 1 minim Alcohol (90 per cent) 3 ounces

Dissolve.

Mix solutions A and B, make up to 20 fluidounces with distilled water, and filter.

«Oil of Cinnamon as an Antiseptic.»—Oil of cinnamon in a 9-per-cent emulsion, when used upon the hands, completely sterilizes them. A 7- to 8-per-cent emulsion is equal to a 1-per-cent solution of corrosive sublimate and is certainly far more agreeable to use. Oil of thyme in an 11-per-cent solution is equal to a 7-per-cent solution of cinnamon oil.

«Green Coloring for Antiseptic Solutions.»—The safest coloring substance for use in a preparation intended either for internal administration or for application to the skin is the coloring matter of leaves, chlorophyll. A tincture of spinach or of grass made by macerating 2 ounces of the freshly cut leaves in a pint of alcohol for five days will be found to give good results. If the pure coloring substance is wanted the solvent should be evaporated off.

«Antiseptic Bromine Solution.»—

Bromine 1 ounce Sodium chloride 8 ounces Water 8 pints

Dissolve the sodium chloride in the water and add the bromine. This solution is to be diluted, when applied to broken skin surfaces, 1 part with 15 parts of water.
