To Preserve and Strengthen the Hair

One ounce of bi-carbonate of soda, two drams of tincture of cantharides, two ounces of spirits of rosemary, and a half pint of rosewater. Mix the bi-carbonate of soda with the rosewater, and add the other ingredients. Apply it with a sponge, rubbing it well into the roots of the hair until a lather is produced; then rinse with water, and dry on a coarse towel.
