other, The Destruction of Tobacco in America,t in November, 
1897. 
OT ecient Leads to Renewed Effort.—Notwithstanding 
the bitter disappointment in connection with the death of Professor 
Flickiger, the effort to complete the record of American drugs con- 
tinued. To this end every sacrifice was made in the way of time, as 
well as of money investment, in the earnest hope that younger men, 
more favorably situated, educationally and otherwise, might ultimately 
take up the work begun by the founders of the Lloyd Library in Drugs 
and Medicines of North America, their publication of twenty-five years 
ago. While in their own direction the accomplishment of this object 
seems no longer possible of attainment, comes a no less hopeful and 
enthusiastic delight in contemplating what others will yet enjoy in a 
future day, when the Lloyd Library will be a contributing factor to 
another’s opportunity. 
May not the writer, then, be pardoned for repeating that this 
struggle of the past has not been altogether fruitless, inasmuch as the 
additions to the Lloyd Library have been earnestly studied as they were 
collected, thus affording a recreative effort and a stimulus that of ne- 
cessity enriches knowledge, broadens views, and enlarges opportunities ? 
Credit Be to Whom Credit is Due.—The foregoing, partially 
explanatory remarks, touching briefly upon the historical features of the 
abandoned work to which allusion has so frequently been made, will 
introduce the text of this Bulletin of the Lloyd Library. The history 
of such vegetable drugs as are included herein embraces every Phar- 
macopeial vegetable representative of the Pharmacopeia of the United 
States, Eighth Decennial Revision, 1900. In preparing this work, the 
writer has been continually impressed with the fact that the comforts 
and the triumphs of man, in the present, are made possible by the 
struggles and the sacrifices of men of the past. It is evident, further- 
more, that if past events indicate the future’s trend, other links, yet to 
be added to the lengthening chain, will leave whosoever is now ccn- 
spicuous in this moment of the passing along an empirical pioneer, as 
contrasted with the man who stands in the sunshine of the sciences 
of the future. 
In this connection it may be recalled that, at the meeting of the 
American Pharmaceutical Association in Los Angeles, 1909, this writer 
contributed a paper put together on the spur of the moment, titied 
Schaer, of Strassburg University, who translated into German the accom- 
panying work by Professor Lloyd on American Manna, for the pages of 
the Berichte der Deutschen Pharmaceutischen Gesellschaft. 
We present herein, with the knowledge and consent of Prof. Schaer and 
the author, the original paper on American Manna.—Editor Am. Jour. Pharm. 
+ When Prof. Fliickiger visited America (July, 1894), he hoped to ob- 
tain historical data that would enable him to give the records of several in- 
teresting American productions. In this he failed, and he then associated 
in his behalf the services of the author of this paper. After much of the 
work had been done, the death of Professor Fliickiger interrupted the in- 
vestigation. This paper on Tobacco was one of the subjects considered —
