291. A GOOD TOOTH POWDER.

To make a good tooth-powder, leave out the coral, and in its place put in pieces of brown stone-ware, reduced to a very fine powder. This is the common way of making it.

292. AN ASTRINGENT FOR THE TEETH.

Take of fresh conserve of roses, 2 ounces, the juice of half a sour lemon, a little very rough claret, and 6 ounces of coral tooth-powder. Make them into a paste, which put into small pots; and, if it dry by standing, moisten with lemon juice and wine, as before.

293. TO CLEAN THE TEETH.

Take of good soft water, 1 quart,
juice of lemon, 2 ounces,
burnt alum, 6 grains,
common salt, 6 grains.

Mix.

Boil them a minute in a cup, then strain and bottle for use: rub the teeth with a small bit of sponge tied to a stick, once a week.
