To Prevent Gray Hair
When the hair begins to change color, the use of the following pomade has a beneficial effect in preventing the disease extending, and has the character of even restoring the color of the hair in many instances: Lard, 4 ounces: spermaceti, 4 drachms: oxide of bismuth, 4 drachms. Melt the lard and spermaceti together, and when getting cold stir in the bismuth; to this can be added any kind of perfume, according to choice. It should be used whenever the hair requires dressing. It must not be imagined that any good effect speedily results; it is, in general, a long time taking place, the change being very gradual.
