ACKNOWLEDGMENTS 



Botanic data. Wood's "American Botanist," Ber- 

 gen's "Botany," "Medical Botany of North Amer- 

 ica," Laurence Johnson, and several special works. 



Chemical data. - "The U. S. Dispensatory," 

 "King's American Dispensatory," "The Prac- 

 titioner's Encyclopedia" edited by Brown and 

 Murphy. To this latter volume I am indebted 

 for English data, particularly to the section on 

 Pharmacology. "Physiological Chemistry" by 

 Mathews and a number of other texts were freely 

 used. 



Pharmacopeial information was derived from the 

 various pharmacopeias, from the U. S. Pharmacopeia 

 IX, and from a series in the Journal of the American 

 Pharmaceutical Association by E. N. Gathercoal and 

 entitled "Pharmacopeial Botanic Drugs of the 

 Twentieth Century." 



New products were looked up from various sources, 

 largely "New and Nonofficial Remedies 1916," 

 published by the American Medical Association, 

 and the Merck publications. 



Pharmacologic data was derived from the writings 

 of Wilcox, Hoyt, Cow, Dale, Cushny, Hatcher, 

 Wilbert, H. C. Wood, Jr., Kobert, Fortescue- 

 Brickdale, and others, as well as from the files of 

 pharmacologic journals. 



Therapeutic data was derived from so wide a 

 range of books as to make invidious any especial 

 mention.
