FUMIGATING PAPER. Bring into a capacious shallow dish a quantity of fumigating balsam and repeatedly draw sheets of card-board through it, allowing the sheets to thoroughly drain off and dry after each drawing through. After repeating the operation about four times, the sheets will be sufficiently perfumed and are then coated by means of a fine brush with a solution of gum-arabic in rose water. This gives to the sheets a dull lustre, while the thin layer of gum-arabic also prevents the volatilization of the aroma. The sheets thus perfumed are cut up into pieces the size of a playing card, and six to twelve such pieces put up in an envelope. For use the paper is not ignited, but only heated. With one such piece a room can be several times perfumed. It may be remarked that before perfuming, the name of the firm, directions for use, etc., are generally printed upon the card-board. FUMIGATING PASTILLES. Some perfumers make more or less a specialty of the manufacture of fumigating pastilles. They are generally of a red or black color, different perfumes, names and qualities. To prepare them, the finely pulverized substances are passed through a sieve and mixed in a capacious dish with the volatile oils, tinctures, etc. The mixture of powder and perfume is then made into a mass with a mucilage of gum tragacanth, which is thoroughly kneaded to make it homogeneous. The saltpetre given in the receipts is dissolved by itself in distilled water and last of all added to the mass. Its object is to keep the pastilles burning after ignition. As regards the mucilage of gum-tragacanth, it may be said that it readily spoils, especially in summer. When it begins to get watery it is already useless and soon acquires a bad odor; by decomposition it loses its cementing power. Hence only a sufficient quantity for immediate use should be made at one time. The moulding of the pastilles is very simple. A number of tin cones into which the mass is pressed are used for the purpose. After standing for a short time the pastilles are taken from the moulds and allowed to dry. _Ordinary red fumigating pastilles._--Pulverized sanders wood and pulverized Sumatra benzoin each 2 lbs., finely pulverized sandarac and olibanum each 1 lb., saltpetre 4¼ ozs. dissolved in distilled water; clove oil 5½ drachms, palmarosa oil 11 drachms, lavender oil 14 drachms.
