Professor Daniel Vaughn was one whose life lines ran nearly parallel with those of the late Professor C. S. Rafinesque, whose eventful history has been so graphically written by Professor R. Ellsworth Call. The cups of these two talented men were filled with privation's bitterness, and in no other place has this writer known the phrase "The Deadly Parallel" so aptly appropriate. Both came to America, scholars, scientists by education; both traveled through Kentucky, teachers; both gave freely to the world, and both suffered in their old age, dying in poverty--Rafinesque perishing in misery in Philadelphia and Vaughn in Cincinnati. Daniel Vaughn was not a myth, and, in order that the reader may know something of the life and fate of this eccentric man, an appendix has been added to this edition of Etidorhpa, in which a picture of his face is shown as the writer knew it in life, and in which brief mention is made of his record. The author here extends his thanks to Professor Richard Nelson and to Father Eugene Brady for their kindness to the readers of Etidorhpa and himself, for to these gentlemen is due the credit of the appended historical note. J. U. L. A VALUABLE AND UNIQUE LIBRARY. From the Pharmaceutical Era, New York, October, 1894. In Cincinnati is one of the most famous botanical and pharmacal libraries in the world, and by scientists it is regarded as an invaluable store of knowledge upon those branches of medical science. So famous is it that one of the most noted pharmacologists and chemists of Germany, on a recent trip to this country, availed himself of its rich collection as a necessary means of completing his study in the line of special drug history. When it is known that he has devoted a life of nearly eighty years to the study of pharmacology, and is an emeritus professor in the famous University of Strassburg, the importance of his action will be understood and appreciated. We refer to Prof. Frederick Flueckiger, who, in connection with Daniel Hanbury, wrote Pharmacographia and other standard works. Attached to the library is an herbarium, begun by Mr. Curtis Gates Lloyd when a schoolboy, in which are to be found over 30,000 specimens of the flora of almost every civilized country on the globe. The collections are the work of two brothers, begun when in early boyhood. In money they are priceless, yet it is the intention of the founders that they shall be placed, either before or at their death, in some college or university where all students may have access to them without cost or favor, and their wills are already made to this end, although the institution to receive the bequest is not yet selected. Eager requests have been made that they be sent to foreign universities, where only, some persons believe, they can receive the appreciation they deserve.
