authorities of the Philadelphia Academy of Sciences the gratitude 

 of the authors and of every scientific person interested in this sub- 

 ject is due in unstinted measure. Under Mr. Stewardson Brown, 

 Curator of the herbarium, and Dr. Witmer Stone during Mr. Brown's 

 absence, every facility that the Academy could offer has been placed 

 freely at the disposal of the authors. 



Rusts of North America Recorded by Schweinitz. 



The arrangement is that in Schweinitz's Synopsis Fungorum in 

 America Boreali. Additions to the translation of the original text 

 are in square brackets. The general serial number is followed 

 by the species number under each genus. As stated by Schweinitz 

 on page 144 of his work " species preceded by an asterisk are those 

 not recorded in the ' Synopsis Fungorum Carolinse Superioris.' 

 Species with L.v.S. added were first described by me either in my 

 previous work or in the present one." 



After the complete record for each number the corresponding 

 record in his " Synopsis Fungorum Carolinas Superioris," if there 

 is one, is given in parentheses. 



Following the English version of Schweinitz's words is a state- 

 ment of the material to represent the number as it occurs in the 

 Schweinitz Herbarium at the Philadelphia Academy of Sciences at 

 the present time, the data on the packets being copied exactly as to 

 spelling, capitals, punctuation, etc. Finally come comments by the 

 authors.
