With deep appreciation do we recall the cordial manner in which the late Prof. Flückiger extended the privilege of his publications, a favor we gladly accepted and freely used. It would be impractical to attempt to mention herein all the journals and standard works, both foreign and American, that have been consulted in the preparation of this publication; these when drawn from are especially credited in the text, but we can not forbear naming a few to which we are especially indebted:

Prof. S. P. Sadtler, Handbook of Industrial Organic Chemistry.
Husemann & Hilger, Pflanzenstoffe, etc.
Prof. Henry Trimble, The Tannins.
