Pastille

Chambers's Encyclopaedia, Volume 7: Maltebrun to Pearson, p. 796

Pastille, usually an aromatic paste or mixture, such as fumigating pastilles, which are burned either as incense or as a means of diffusing an agreeable odour. They are composed of charcoal powder, with such aromatic gums as benzoin, ladanum, &c., and powders of sweet-scented woods and barks, as sandalwood, cinnamon, and especially cascarilla barks. Essential oils are also added, and the whole are worked into a paste with a little gummeilage, and formed into small sharp-pointed cones about an inch and a half high, and half an inch broad at the base. When perfectly dry they are used by lighting at the point, and as they burn down an agreeable odour is given out with the smoke. Another kind of pastille, usually in the form of a small pill covered with gold or silver leaf, is used for perfuming the breath; it is made of similar ingredients, excepting the charcoal.
