THE ESSENTIAL OILS Vol. III

---

The third and the succeeding volumes of the series "The Essential Oils" will consist of monographs on individual oils, describing their botanical and geographical origin, methods of cultivation of the plants from which they are derived, techniques of distillation and yield of oil, their physicochemical properties, chemical composition, total production, and uses in the industry.

The individual oils are grouped within the families to which the re- spective aromatic plants belong, but in the sequence of the plant families no botanical system is followed. This arrangement has been chosen for the practical purpose of giving first place to those families the essential oils of which are technically and commercially most important. Thus, the present volume will describe the oils of the plant families Rutaceae (with special emphasis on the very important citrus oils) and Labiatae. The policy of arranging the families according to commercial and practical utility will be adhered to throughout the following volumes, but at the end of the last volume there will be a table or key showing the classifica- tion of the essential oils according to a modern botanical system. This policy will permit greater flexibility and ease in the sequence of the various oils than could be achieved by following a rigid system of plant taxonomy.

The literature on essential oils accumulated during the last hundred years contains references to thousands of oils that have been produced in various countries on a purely experimental basis. However, much of the data on these experimental oils, particularly their plant origin, are badly confused, if not outright contradictory. No real purpose would be served by including these unimportant oils in a work intended for practical use, and whose scope must be limited of necessity. The author has, therefore, decided to describe only those oils that are of technical importance and actually used in our industry, or offer at least commercial possibilities, or incite particular scientific interest. It appears preferable to describe these oils from every angle and on good authority, rather than to indulge in a futile discussion on countless experimental oils about which many factors, particularly heir botanical origin, are highly questionable.

In the discussion of each individual oil the author has depended not only upon his own experience accumulated during many years of work in the essential oil-producing regions all over the world, but also upon the experi- ence of Fritzsche Brothers, Inc., New York, in producing and handling essential oils for almost eighty years. Moreover, the voluminous literature on the subject, representing the result of research by hundreds of promi- nent scientists, has been carefully screened and edited, with a view to excluding data that might appear dubious. Wherever this was not possible, the original findings have been cited with reserve and as questionable.

The collection of the author's own data would, of course, have been im- possible without the wholehearted and splendid cooperation of hundreds of planters, essential oil producers and dealers in every part of the world.
