Distilling Plants

It is the plan of this volume to describe, from a general point of view, the history, chemistry, biological origin and functions of the essential oils, method of production and analysis. This is the author’s motive for the present treatise on the production, chemistry, analysis and application of these interesting and important products. It has been the author’s rare privilege to witness most of these developments first hand in his travels that have lasted for more than twenty years. They have taken him the length and breadth of Europe, through Africa, Asia, Australia, into the new producing centres of North, Central and South America—in all of which places he surveyed the production of essential oils at their source.
