JOURNAL OF THE SOCIETY OF COSMETIC CHEMISTS application and the botanical families. In the third part, the components of the various oils are listed both in alphabetical order of the oils and the components themselves. Section 4 deals with their more important proper- ties, and Section 5 with yields, geographical distribution and annual produc- tion figures. Section 6 deals with rare oils and Section 7 gives details of the harvest seasons. In Section 8, the physical properties are dealt with, while Section 9 deals with terpeneless oils. Section 10 is concerned with historical details and bibliography, and Section 11, with resins and balsams. Section 12 lists some of the foreign (cf. non-German) names for the various oils, but this Section in particular could be improved by subdivision into the various languages. The last section lists manufacturers of essential oils, and suggested reading matter. Altogether, this book appears to contain a lot of useful information, though it is somewhat difficult to understand the basis for some of the classifications without having read the book to which this volume is the supplement.
