Tincture of civet is exceedingly lasting and is generally employed for fixing other odors. As to the quantity required to fix perfumes in general, we may state that it varies with the nature of the odor. As a rule, about one-sixteenth part of tincture of civet suffices for even the most volatile perfumes.
