biography 'but contains many of the facts of Schweinitz's life 

 and as it was compiled shortly after his death by a personal 

 friend is the most direct source of information concerning his 

 life and botanical work. Briefer sketches have been published by 

 Morgan (10), Kellerman (7), Shear (14), Harshberger (5), and 

 Lloyd (9). These are largely compiled from the memoir by 

 Johnson and contain no new material. 



Unsigned biographical sketches have been published in the 

 Journal of the Elisha Mitchell Scientific Society for 1886 and in 

 Popular Science Monthly for April, 1894. The former (4) ap- 

 pears to have been prepared by Professor J. W. Gore, at that 

 time resident vice-president of the Society. In addition to data 

 given by Johnson this paper contains some material obtained 

 from Schweinitz's second son, Bishop Edmund de Schweinitz, of 

 Bethlehem, Pa. The latter (16) is one of a series of biogra- 

 phies which appeared in Popular Science Monthly, most of which 

 were anonymous and were prepared, presumably, by Dr. Wil- 

 liam J. Youmans, then editor of the Journal. This paper con- 

 tains information as to Schweinitz's sons, obtained probably from 

 his second son, Robert. 



October 27, 1904, Miss E. A. Lehman presented a paper on 

 Schweinitz ,(8) before the Wachovia Historical Society, of Salem, 

 N. C. Miss Lehman has informed the writers that the material 

 for this paper was largely furnished by Miss Adelaide Fries, a 

 great granddaughter of Schweinitz who has made a special study 

 of the history of the Moravians in the vicinity of Winston- 

 Salem, N. C. 



Recently, in connection with studies of the genus Endothia, the 

 writers have had occasion to publish considerable information 

 concerning Schweinitz's methods of work, together with illustra- 

 tions of some of his manuscripts and specimens. 



In addition to these publications the writers have had access 

 to the Schweinitz manuscripts preserved in the library of the 

 Philadelphia Academy of Sciences ; his correspondence partly in 

 the possession of his grandson, Dr. George de Schweinitz, of 

 Philadelphia, and partly in the Philadelphia Academy ; and many 

 of his letters to Torrey now preserved at the New York Botan- 

 ical Garden. In assembling information regarding the history
