| Thymol | 22 grains | |
| Eucalyptol | 20 drops | |
| Menthol | 1 1/2 grains | |
| Phenol | 15 grains | |
| Oil of gaultheria | 4 drops | |
| Carmine to give a pink tint. | ||
| II.— | Alum, powdered | 50 parts by weight |
| Borax, powdered | 50 parts by weight | |
| Carbolic acid, crystals | 5 parts by weight | |
| Oil of eucalyptus | 5 parts by weight | |
| Oil of wintergreen | 5 parts by weight | |
| Menthol | 5 parts by weight | |
| Thymol | 5 parts by weight | |
| III.— | Boracic acid | 10 ounces |
| Sodium biborate | 4 ounces | |
| Alum | 1 ounce | |
| Zinc sulphocarbolate | 1 ounce | |
| Thymic acid | 1 drachm. |
Mix thoroughly. For an antiseptic wash dissolve 1 or 2 drachms in a quart of warm water.
IV.—Ektogan is a new dusting powder which is a mixture of zinc hydroxide and dioxide. It is equivalent to about 8 per cent of active oxygen. It is a yellowish-white odorless and tasteless powder, insoluble in water. It is used externally in wounds and in skin diseases as a moist dressing mixed with citric, tartaric, or {99} tannic acid, which causes the liberation of oxygen. With iodides it liberates iodine. It is stated to be strongly antiseptic; it is used in the form of a powder, a gauze, and a plaster.
Antiseptic Pencils.—
| I.— | Tannin | q. s. |
|---|---|---|
| Alcohol, q. s | 1 part | |
| Ether, q. s | 3 parts |
Make into a mass, using as an excipient the alcohol and ether previously mixed. Roll into pencils of the desired length and thickness. Then coat with collodion, roll in pure silver leaf, and finally coat with the following solution of gelatine and set aside to dry:
| Gelatine | 1 drachm |
| Water | 1 pint |
Dissolve by the aid of a gentle heat.
When wanted for use, shave away a portion of the covering, dip the pencil into tepid water and apply.
II.—Pencils for stopping bleeding are prepared by mixing:
| Purified alum | 480 parts by weight |
| Borax | 24 parts by weight |
| Oxide zinc | 2 1/2 parts by weight |
| Thymol | 8 parts by weight |
| Formalin | 4 parts by weight |
Melting carefully in a water bath, adding some perfume, and forming mixture into pencils or cones.
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 (Poison) for Organic Specimens.—
| (a) | Wheat flour | 16 ounces |
|---|---|---|
| Beat to a batter with cold water | 16 fluidounces | |
| Then pour into boiling water | 32 fluidounces | |
| (b) | Pulverized gum arabic | 2 ounces |
| Dissolve in boiling water | 4 fluidounces | |
| (c) | Pulverized alum | 2 ounces |
| Dissolve in boiling water | 4 fluidounces | |
| (d) | Acetate of lead | 2 ounces |
| Dissolve in boiling water | 4 fluidounces | |
| (e) | Corrosive sublimate | 10 grains |
Mix (a) and (b) while hot and continue to simmer; meanwhile stir in (c) and mix thoroughly; then add (d). Stir briskly, and pour in the dry corrosive sublimate. This paste is very poisonous. It is used for anatomical work and for pasting organic tissue, labels on skeletons, etc.

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.

| 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.
