Tooth Powder
Precipitated chalk, seven ounces; Florentine orris, four ounces; bicarbonate of soda, three ounces; powdered white Castile soap, two ounces; thirty drops each of oil of wintergreen and sassafras. Sift all together and keep in a glass jar or tin box. A very valuable recipe for hardening the teeth.

An Indispensable Powder
A trouble scarcely to be named among refined persons is profuse perspiration, which ruins clothing and comfort alike. For this it is recommended to bathe frequently, putting into the water a cold infusion of rosemary, sage or thyme, and afterward dust the under-garments with a mixture of two and a half drachms of camphor, four ounces of orris-root, and sixteen ounces of starch, the whole reduced to impalpable powder. Tie it in a coarse muslin bag, (or one made of flannel is better if you wish to use it on the flesh,) and shake it over the clothes. This makes a very fine bathing powder.
