Shear-Stevens: Mycological Work of M. A. Curtis 193 



the species are checked, evidently with the intention of indicating 

 whether or not Curtis actually saw the specimens in the Schwei^ 

 nitz herbarium. 



Regarding the preparation of the joint paper referred to above, 

 the writers have found no correspondence. There are however 

 in the files of the Philadelphia Academy of Natural Sciences 

 several letters from Curtis which indicate that he prepared the 

 material for the press, and corrected the proof. Portions of these 

 letters which were probably written to Dr. Zantzinger, then sec- 

 retary of the Academy and which are self explanatory, are pub- 

 Hshed below. 



Society Hill, S. Car. Jan: 17th, '53. 



Dear Sir: 



There is now nearly ready a paper upon the Exotic Fungi 

 of Herb. Schwein : which he never published. Mr. Berkeley 

 thought it best to begin with these, as being material mostly 

 new. The notice of his American species will follow in time, 

 as we can reduce the materials. The task is more difficult 

 than I had anticipated. 



Please inform me then, zvhcn you will be ready to pub- 

 lish this paper ; — whether in quarto or octavo size ; — & in 

 regard to proofs, whether you allow us any copies, & how 

 many. 



Society Hill, S. Car. Feb. ist, 1853. 



Dear Sir: 



Your favor is received. — The paper on the Schweinitzian 

 Fungi is not quite completed, but I hope to be able to for- 

 ward it in four or five days. — In the meantime I send you the 

 drawings by Mr. Berkeley sufficient for one Plate. It is 

 doubtful if I shall have enough for another Plate. If not, 

 there will be no more sent. 



I will be obliged to you for proofs of the Plate and Letter 

 Press. — Your allowance of 20 copies to the Author is very 

 liberal, & we will be obliged to you for them. — Please have 

 10 sent to me, & retain the others until I learn what disposi- 

 tion Mr. Berkeley will have me make of it. 



With many thanks for your uniform courtesy, I remain, 

 dear sir. 



Very respectfully & truly yours, 



M. A. Curtis.
