Tincture of cantharides (see above, page 281) 1¾ oz. Tincture of nut-galls 1¾ oz. Extract of musk 150 grains. Carmine 75 grains. Alcohol 3½ oz. Rose water 1 qt. Tincture of nut-galls is made by macerating 3½ oz. of powdered nut-galls in one quart of alcohol. The tincture of cinchona in the following formula is prepared in the same manner.

Formulas for similar hair tonics might be given to the number of several hundreds; but we repeat what we have said above—they do not produce the desired result. While the well-known bay rum is used more as a face lotion or refreshing skin tonic, particularly after shaving, or when perspiring in hot weather, yet it is also often used as a wash for the scalp, and is popularly believed to stimulate the growth of hair, which is in reality not the case. We shall therefore give a formula for its preparation here: BAY RUM. Oil of bay (from Myrcia acris) 240 grains. Oil of orange (bigarade) 16 grains. Oil of Pimenta 16 grains. Alcohol 1 qt. Water 25 fl. oz. Dissolve the oils in the alcohol and add the water. Mix the liquid with about 2 oz. of precipitated phosphate of lime, and filter. It will improve by age. Genuine bay rum is imported from the West Indies (St. Thomas, etc.), where a crude kind of alcohol, obtained in connection with the manufacture of rum from molasses, is distilled with the fresh leaves of the bay-tree (Myrcia acris). The oil of bay obtained from this must not be confounded with the oil of sweet bay. The latter, as it appears in commerce, is a crude mixture of a fixed with a volatile oil. CHAPTER XXVIII.
