Part 174

Dissolve the alum in one half gallon of boiling water, and add the sodium carbonate; then add hydrochloric acid until the precipitate formed is dissolved. Dissolve the other salt in water and add to the previous solution. Finally add enough water to make the whole measure 1 gallon, and filter.

In use, this is diluted with 7 parts of water.

II.—For the Sick Room.—In using this ventilate frequently: Guaiac, 10 parts; eucalyptol, 8 parts; phenol, 6 parts; menthol, 4 parts; thymol, 2 parts; oil of cloves, 1 part; alcohol of 90 per cent, 170 parts.

Atomizer Liquid for Sick Rooms.—

III.—Eucalyptol 10 parts by weight Thyme oil 5 parts by weight Lemon oil 5 parts by weight Lavender oil 5 parts by weight Spirit, 90 per cent 110 parts by weight

To a pint of water a teaspoonful for evaporation.

Non-Poisonous Sheep Dips.—Paste.—

I.—Creosote (containing 15 per cent to 20 per cent of carbolic acid) 2 parts Stearine or Yorkshire grease specific gravity, 1340 1 part Black rosin, 5 per cent to 10 per cent.

Melt the rosin and add grease and soda lyes, and then add creosote cold.

II.—Creosote 1 part Crude hard rosin oil 1 part

Put rosin oil in copper and heat to about 220° F., and add as much caustic soda powder, 98 per cent strength, as the oil will take up. The quantity depends upon the amount of acetic acid in the oil. If too much soda is added it will remain at the bottom. When the rosin oil has taken up the soda add creosote, and let it stand.

«Odorless Disinfectants.»—

I.—Ferric chloride 4 parts Zinc chloride 5 parts Aluminum chloride 5 parts Calcium chloride 4 parts Manganese chloride 3 parts Water 69 parts

If desired, 10 grains thymol and 2 fluidrachms oil of rosemary, previously dissolved in about 12 fluidrachms of alcohol, may be added to each gallon.

II.—Alum 10 parts Sodium carbonate 10 parts Ammonium chloride 2 parts Sodium chloride 2 parts Zinc chloride 1 part Hydrochloric acid, sufficient. Water 100 parts

Dissolve the alum in about 50 parts boiling water and add the sodium carbonate. The resulting precipitate of aluminum hydrate dissolve with the aid of just sufficient hydrochloric acid, and add the other ingredients previously dissolved in the remainder of the water.

III.—Mercuric chloride 1 part Cupric sulphate 10 parts Zinc sulphate 50 parts Sodium chloride 65 parts Water to make 1,000 parts.

«Paris Salts.»—The disinfectant known by this name is a mixture made from the following recipe:

Zinc sulphate 49 parts Ammonia alum 49 parts Potash permanganate 1 part Lime 1 part

The ingredients are fused together, mixed with a little calcium chloride, and perfumed with thymol.

«Platt’s Chlorides.»—

I.—Aluminum sulphate 6 ounces Zinc chloride 1 1⁠/⁠2 ounces Sodium chloride 2 ounces Calcium chloride 3 ounces Water enough to make 2 pints.

II.—A more elaborate formula for a preparation said to resemble the proprietary article is as follows: {265}

Zinc, in strips 4 ounces Lead carbonate 2 ounces Chlorinated lime 1 ounce Magnesium carbonate 1⁠/⁠2 ounce Aluminum hydrate 1 1⁠/⁠2 ounces Potassium hydrate 1⁠/⁠2 ounce Hydrochloric acid 16 ounces Water 16 ounces Whiting, enough.

Dissolve the zinc in the acid; then add the other salts singly in the order named, letting each dissolve before the next is added. When all are dissolved add the water to the solution, and after a couple of hours add a little whiting to neutralize any excess of acid; then filter.

Zinc chloride ranks very low among disinfectants, and the use of such solutions as these, by giving a false sense of security from disease germs, may be the means of spreading rather than of checking the spread of sickness.

«Disinfecting Coating.»—Carbolic acid, 2 parts; manganese, 3 parts; calcium chloride, 2 parts; china clay, 10 parts; infusorial earth, 4 parts; dextrin, 2 parts; and water, 10 parts.
