Mycologia 



As is indicated by the introduction this is supplementary to the 

 paper on the fungi of North Carolina. 



Schweinitz's last and most important published work was the 

 Synopsis Fungorum in America Boreali (13). This was pub- 

 lished by the American Philosophical Society, Philadelphia, in 

 the volume of Proceedings dated 1834. It was, however, actually 

 issued as a separate two years earlier, as shown 'by the following 

 note now in the possession of Dr. George de Schweinitz, of 

 Philadelphia.

In a letter dated October 22, 1832, Torrey acknowledges the 

 receipt of two copies, one intended for Halsey, and takes the 

 opportunity to congratulate his friend on the " completion of 

 this great performance." He adds this pertinent remark, "If we 

 now had the other departments of our Acotyledones finished, we 

 would have our entire Flora posted up to the present day. When 

 shall we have our Lichens, our Musci, our Algae & our Hepati- 

 cae? Life is too short — too valuable, I ought to have said, for 

 any one of us to undertake the whole." 



Manuscripts 



Johnson (6 p. 36-38) mentions, in addition to Schweinitz's 

 published works, " other productions of his pen . . . some of 

 which still remain in manuscript." Of these manuscripts a num- 

 ber are known to have been preserved. Mr. Eugene A. Rau 

 informs the writers that he has several manuscripts given to him 

 by one of Schweinitz's granddaughters, among these is Schwei-
