The lasting odor of Russia leather is familiar to all and pleasing to many; its perfume is due to the aromatic saunders-wood with which it is tanned, and to the empyreumatic oil of the bark of the birch tree, with which it is curried. The odor of Russia leather is, however, not _recherche_ enough to be considered as a perfume; but, nevertheless, leather can be impregnated by steeping in the various ottos with any sweet scent, and which it retains to a remarkable degree, especially with otto of santal or lemon-grass (_Verbena_). In this manner the odor of the peau d'Espagne can be greatly varied, and gives great satisfaction, on account of the permanence of its perfume. PERFUMED LETTER-PAPER. If a piece of peau d'Espagne be placed in contact with paper, the latter absorbs sufficient odor to be considered as "perfumed;" it is obvious that paper for writing upon must not be touched with any of the odorous tinctures or ottos, on account of such matters interfering with the fluidity of the ink and action of the pen; therefore, by the process of infection, as it were, alone can writing paper be perfumed to advantage. Besides the sachets mentioned there are many other substances applied as dry perfumes, such as scented wadding, used for quilting into all sorts of articles adapted for use in a lady's boudoir. Pincushions, jewel cases, and the like are lined with it. Cotton, so perfumed, is simply steeped in some strong essence of musk, &c. PERFUMED BOOK-MARKERS. We have seen that leather can be impregnated with odoriferous substances, in the manufacture of peau d'Espagne; just so is card-board treated prior to being made up into book-marks. In finishing them for sale, taste alone dictates their design; some are ornamented with beads, others with embroidery. CASSOLETTES AND PRINTANIERS. Cassolettes and Printaniers are little ivory boxes, of various designs, perforated in order to allow the escape of the odors contained therein. The paste used for filling these "ivory palaces whereby we are made glad," is composed of equal parts of grain musk, ambergris, seeds of the vanilla-pod, otto of roses, and orris powder, with enough gum acacia, or gum tragacantha, to work the whole together into a paste. These things are now principally used for perfuming the pocket or reticule, much in the same way that ornamental silver and gold vinagrettes are used. PASTILS. There is no doubt whatever that the origin of the use of pastils, or pastilles, as they are more often called, from the French, has been derived from the use of incense at the altars of the temples during the religious services:--"According to the custom of the priest's office, his lot (Zacharias') was to burn incense when he went into the temple of the Lord." (Luke 1:9.) "And thou shalt make an altar to burn incense.... And Aaron shall burn thereon sweet incense every morning when he dresseth the lamps, and at even when he lighteth the lamps he shall burn incense upon it." (Exodus 30.)
