INTRODUCTION.

the foremost pharmacologist of the world. With Daniel Hanbury, hehad just completed the monumental work on European and Orientaldrugs, (including the principal drugs of other parts of the world)known as the Pharrmcographia, and was ambitious to continue, in likemanner, with the medicinal products of North America. In July, 1894,Professor Flückiger visited America, where he was the guest of therenowned American pharmacists, Dr. Edward R. Squibb, of Brooklyn,and Dr. Frederick Hoffman, of New York City. He had arranged tovisit Cincinnati and consummate here a plan for the detailed study ofthe North American pharmacography, but a period of intense heatthen chanced to prevail throughout America, and the aged professorwas forced, reluctantly, to abandon his journey to this city. The writerthen selected and forwarded to Professor Flückiger, for review, severalcases of books dealing with the early American materia medica, such asdomestic writings, early American travels, Eclectic and Thomsonianliterature, as well as publications of primitive days concerning familymedicines and connected preparations. These very much delightedand even surprised Professor Flückiger, both as regards variety andContents. It was then tentatively arranged that a Pharmacographyof North American Medicinal Plauts and Drugs should be at once in-augurated, the responsibility of the chemistry and the correlation of thechemical and proximate products derived from the American materiamedica being assnmed by Professor Flückiger, as well as the system-atic research of foreign publications in those directions. He designed,also, to Institute a series of original investigations in his laboratory,at Strassburg University. The Lloyd Library seemed, even then, com-petent to furnish the historical data sufficient to establish the recordsof the plants considered, this writer (John Uri Lloyd) accepting theresponsibility of the history, including the sophistications and descrip-tions of the parts used in medicine, whilst the botanical history, re-lationships, and kindred descriptions were to be the care of Mr. CurtisGates Lloyd. The publication was thus to partake of the plan of bothDrugs and Medicines of North America, and the Pharmacographia ofFlückiger and Hanbury, so well known and so thoroughly established.The work was accordingly commenced, and several historical articleswere prepared by the writer. a few of which were forwarded to Pro-fessor Flückiger. The unfortunate and lamentable death of that world-renowned pharmacologist, within a very short time after his returnto Europe, terminated the enterprise, bringing to the writer one of thegreatest disappointments of his life.

Of the drug articles thus prepared for Professor Flückiger, twowere subsequentlv published in the American Journal of Pharmacy,one, titled The California Manna* appearing in July, 1897, and the

In this he failed, and he then associated in hisbehalf the Services of the author of this paper. After much of the work hadbeen done, the death of Prof. Flückiger interrupted the investigation.
