ashcolored

— The colors of Ambergrease vary; there is, first, the white Ambergrease, which is scarce and of little value; as it seems, either not to be ripe, or mixed with some heterogeneous matter; then, the ashcolored or true Ambergrease; afterwards the black Ambergrease , which is inferior to the preceding sort, and frequently adulterated; lastly, the brown Ambergrease, which has a particular, unpleasant smell.
