C. Fumigating Ribbons

are nothing but fine flat lamp wicks treated first with saltpetre solution and then with the preceding mixture. The wick is rolled up and placed in a vessel provided with a lamp burner. It is inserted in the burner like any other wick and when lighted burns down to the metal and goes out unless screwed up higher. Fumigating vessels provided with these wicks are very practical because, if artistic in form, they form quite an ornament to the room and can be instantly set in operation. A French formula gives the following mixture for saturating the wicks:

Benzoin1 lb.
Musk¾ oz.
Myrrh3½ oz.
Tolu balsam3½ oz.
Tincture of orris root1 pint.
Oil of rose15 grains.
