So. fora proper choice of perfumes, we must take into con sideration the ingredients used in them. These ingredients may he likened to the individual notes used in com posing a piece of musk* or the pigments employed for painting a picture. They fall into three groups: the natural ani mal substances; the natural floral oils or "essential oils," and the synthetic products which not only duplicate many of the substances found in the first two groups, hut. also include a in mi her ofaromatic products not found in nature. Uf die natural products the most important are mihL ambergris ami eh el. AI usk is obtained from the male musk deer found in I lit! w rids of Tibet.

The essential oils are made from odor-bearing parts of flowers. Their manufacture constitutes a large indus try. principally in Grasse, in Southern France, and Bulgaria where the Jest i Hto of Rose is produced. before science entered perfumer*, I went \ -fhe tons of v solels were needed to make one ounce of natural violet oil, a ton of ros-es w as required to pro duce ten ounces of natural rose oil.

Where two hundred perfume notes existed before, in ihe form of natural products, there are now avail able o* or a thousand different scents. The chemist.V greatest achievement along these lines is tin* development <d synthetic. mu-k, because musk is the most imporlani single material Use<l in perfumery.
