To Make Brown Teeth White

Apply carefully over the teeth, a stick dipped in strong acetic or nitric acid, and immediately wash out the mouth with cold water. To make the teeth even, if irregular, draw a piece of fine cord betwixt them.

Hair Dye

Nitric acid, one part ; nitrate of silver, ten parts ; sap green, nine parts ; powdered gum arabic, two parts ; water, three hundred parts ; essence musii, one or two drops to each bottle. Mix. In all cases, first free the hair from grease, by soap and water. All hair dyes must be applied by means of moistening a comb with them, and passing it through the hair, observing not to touch the skin with the dye.

Warts

Warts, like chilblains, are too well known to require description. They chiefly attack the hands, and particularly the fingers, but sometimes occur on other portions of the body. They may be removed by rubbing or moistening their extremities every day, or every other day, with lunar caustic, nitric acid, concentrated acetic acid, or aromatic vinegar, care being taken not to wash the hands for some hours after. The first is an extremely convenient and manageable substance, from not being liable to drop or spread; but it produces a black stain, which remains till the cauterized surface peels off. The second produces a yellow stain, in depth proportioned to the strength of the acid employed. This also wears off after the lapse of a few days. The others scarcely discolor the skin.

Freckles

Freckles, or the round or oval-shaped yellowish or brownish-yellow spots, resembling stains, common on the face and the backs of the hands of persons with a fair and delicate skin who are much exposed to the direct rays of the sun in hot weather, are of little importance in themselves, and have nothing to do with the general health. Ladies who desire to remove them may have recourse to the frequent application of dilute spirit, or lemon juice, or a lotion formed by adding acetic, hydrochloric, nitric, or sulphuric acid, or liquor of potassa, to water, until it is just strong enough to slightly prick the tongue. One part of good Jamaica rum to two parts of lemon juice or weak vinegar is a good form of lotion for the purpose. The effect of all these lotions is increased by the addition of a little glycerine.

The preceding are also occasionally called “common freckles,” “summer freckles,” and “sun freckles.” In some cases they are very persistent, and resist all attempts to remove them while the exposure that produces them is continued. Their appearance may be prevented by the greater use of the veil, parasol or sunshade, or avoidance of exposure to the sun during the heat of the day.

Another variety, popularly known as cold freckles, occur at all seasons of the year, and usually depend on disordered health or some disturbance of the natural functions of the skin. Here the only external application that proves useful is the solution of bichloride of mercury and glycerine, or Gowland’s lotion.
