THE ESSENTIAL OILS Vol. VI

---

The present volume-the sixth-completes this series on "The Essential Oils." Like the third, fourth, and fifth, it is composed of monographs describing individual oils. Many of these will be of particular interest to the pharmaceutical, flavor and perfume industries: wintergreen, sweet birch, valerian, mustard, onion, hops, wormseed, juniper, labdanum and oak moss-to name only a few. A large section of the volume is devoted to the pine oils, so valuable to manufacturers of soaps, disinfectants, sprays, bath and other seented technical preparations. An authoritative and detailed chapter, by Dr. Leo Goldblatt, deals with the turpentine and related oils of the American Naval Stores Industries.

As was pointed out in the Prefaces to previous volumes, the monographs on individual essential oils are not arranged according to any complete taxonomic system, but follow a sequence considered more convenient for practical use. However, to satisfy the botanist, a table showing the tax- onomic classification of all the essential oils described in these six volumes has been included at the end of the present volume.

In addition to the oils treated in this series there are many more that have been produced on a purely experimental scale during the last fifty or hundred years. However, much of the information on such oils, particu- larly that relating to plant origin, is confused and contradictory. No pur- pose would have been served by including these little-known and often ill- defined oils in this work, in which emphasis has been placed upon oils of technical and scientific importance, and upon reliability of data. Any reader interested in oils of such secondary rank will find the literature on them in the third (German) edition of Gildemeister and Hoffmann's "Die Ätherischen Öle" (1928-31); for later information Chemical Abstracts should be consulted.

The completion of "The Essential Oils" has required more than twenty years of field investigations throughout the oil-producing regions of the world, and ten years of literature research, editing and writing. Much effort and toil have been expended on a task made difficult not only by the continuing rapid progress of chemistry, but also by the profound economic changes that have taken place recently in the essential industry throughout the world. A work originally planned to comprise no more than three volumes has now grown to six-an enterprise of some magnitude for one private concern to have undertaken, particularly in a time of economie and political uncertainty. Mounting costs of research and publication-most unfortunately for science and technology-may deter any future attempt to publish a comparable work in 80 relatively limited a field. It seems not unlikely that in the future comprehensive scientific and technical works on the scale of "The Essential Oils" will have to be compiled by foundations supported financially in a large measure by the particular industry concerned. This should by no means be taken to imply that the present series is the accomplishment of only one individual. It represents a joint effort; as such may it be accepted as a sincere endeavor to present the complete story of those interesting, widely important, and often highly romantic products-the essential oils
