Patchouly Powder.
| Patchouly herb | 2 lb. |
| Oil of patchouly | 30 grains. |
| Musk | 15 grains. |
The musk is rubbed up with gradually increased quantities of the patchouly herb and with the addition of the oil of patchouly; the intimate mixture of the powder saturated with musk and oil of patchouly and the rest of the powder is effected by prolonged stirring of the two powders in a large vessel. The same process is followed with all other dry powders in which a small amount of a solid with intense odor or of an essential oil is to be mixed with a large quantity of powder.
