preface. 
The author deems it a duty to himself to state, 
that the Flora Philadelphica, which he has pledged 
himself to the public to publish, on a large scale, 
and with original plates of most of the unfigured 
plants in our neighbourhood, he is still engaged 
in, and by gradual, slow, but sure steps, he hopes 
in a few years, to present such a work as Ameri- 
cans and foreigners have a right to expect in the 
Flora of Philadelphia, from its distinguished Uni- 
versity.
