Excerpt from The Volatile Oils, Vol. 1: With Two Maps and Numerous Illustrations The translation of such a work should indeed prove of value. To make such a translation and to take cognizance of the numerous contributions on volatile oils and related subjects that have appeared since the original German edition was issued a year ago, has proved a severe task for one whose time was already divided between instructional duties and editorial labors. In judging the English edition, it is hoped that the limitations as to time and the difficulties encountered will be taken into con sideration. Owing to the impossibility of satisfactorily translating many of the numerous quotations in the historical introduction, chapters two and three have been condensed. Inasmuch as but very few if any readers are in a position to consult the numerous historical works quoted by Dr. Hoffmann, all bibliographic information has been placed in an appendix. To the special part a few oils were added, and changes rendered necessary by recent investigations were made as far as time permitted.
