Pliny makes a note of the tree from which frankincense is procured, and certain passages in his works indicate that dried flowers were used in his time by way of perfume, and that they were, as now, mixed with spices, a compound which the modern perfumer calls _pot-pourri_, used for scenting apartments, and generally placed in some ornamental Vase. It was not uncommon among the Egyptian ladies to carry about the person a little pouch of odoriferous gums, as is the case to the present day among the Chinese, and to wear beads made of scented wood. The "bdellium" mentioned by Moses in Genesis is a perfuming gum, resembling frankincense, if not identical with it. Several passages in Exodus prove the use of perfumes at a very early period among the Hebrews. In the thirtieth chapter of Exodus the Lord said unto Moses: "1. And thou shalt make an altar to burn incense upon; of Shittim wood shalt thou make it." "7. And Aaron shall burn thereon sweet incense every morning; when he dresseth the lamps he shall burn incense upon it." "34. Take unto thee sweet spices, stacte, and onycha, and galbanum; these sweet spices with pure frankincense: of each shall there be a like weight." "35. And thou shalt make it a perfume, a confection after the art of the apothecary, tempered together pure and holy." "36. And thou shalt beat some of it very small, and put of it before the testimony in the tabernacle of the congregation, where I will meet with thee; it shall be unto you most holy." "37. And as for the perfume which thou shalt make, ye shall not make to yourselves according to the composition thereof; it shall be unto thee holy for the Lord." "38. Whosoever shall make like unto that to smell thereto, shall even be cut off from his people."
