78 Calendaif of Vegetation, ire. by C. S. Rajinesque, 



ef plants is easily watched, but their foHation and budding 

 ought not to be neglected. Having been prevented, by various 

 causes, from keeping an exact record of the progress of vege- 

 tation near New-York in 1817, I submit an accurate journal 

 which I had kept the year before, at Philadelphia, in which I 

 hope that some interesting facts may be noticed. Dr. Benja- 

 min Barton has published a sketch of a Calendar of Flora for 

 Philadelphia, in his Fragments on the Natural History of Penn- 

 sylvania ; by comparing it with mine, many material differences 

 may be traced, which evince a gradual change of temperature, 

 although the spring of 1816 was remarkably cold and late. 

 The greater quantity of species observed by me may, besides, 

 render this journal a sort of vernal Flora of the neighbourhood 

 of Philadelphia ; and many species found by me are not to be 

 met in the Flora Philadelphica of Dr. William Barton.
