INTRODUCTION. 
ticular reason for so doing. For example, Fliickiger and Hanbury’s 
Pharmacographia, and similar works, are accepted as unimpeachable 
in their reference facts. 
The titles only of authoritative works to which reference might 
have been made would comprise a volume. The list has therefore 
necessarily been restricted to such as are most important. Whoever 
wishes to elaborate any subject herein mentioned, will probably find the 
list suggestively ample, for each, as a rule, carries references to others 
connected therewith. It will be observed that travelers and explorers, 
as well as historians, often first refer to medicines used in the countries 
described by them. In this direction it will be seen that the Lloyd 
Library is particularly fortunate, as concerns its completeness, there 
being at this date 32,434 volumes on its shelves, exclusive of pamphlets. 
The writer wishes, in conclusion, to thank, especially, the Librarian 
of the Lloyd Library, Captain William Holden, to whose painstaking 
care, both in the way of procuring volumes needed and of seeking 
references as required, as well as of compiling the Bibliography, he is 
much indebted. 
To the Assistant Librarian, Miss Edith Wycoff, who has, in this 
as in other directions been exceedingly helpful, the writer expresses 
his sincerest thanks. 
To the writer’s secretary, Miss Margaret Stewart, M. A., are to 
be credited the translations from Greek and Latin authors, as well as 
continued helpful care throughout the entire work. 
Several of the articles herein included (as those on Aloes and 
Pomegranate) are condensations of papers previously published by the 
writer in the Western Druggist, Chicago. To Dr. Sigmund Waldbott, 
then in charge of the Lloyd Library, who was of exceptional service 
in the production of these papers, the writer feels no less indebted now 
than at the time of their original publication. 
For the inspiration of the American Pharmaceutical Association, 
the author is very grateful. A synopsis of the work was prepared for 
the society at its Richmond (1910) meeting, but owing to illness of 
the undersigned was not presented. 
This Bulletin on Pharmacopeial drugs expresses so imperfectly the 
amount of labor that has been expended in its evolution, as to lead the 
author to admit frankly a degree of humiliation because of the paucity 
of returns for so great an outlay of time, study, and library research.
