Laid in the back of the copy there are two admirable pencil 

 drawings of the flowers of the Tobacco and American Colombo 

 both signed J. Cassin. 



These memoranda are of particular interest as they show that 

 at the age of seventeen he had attained a knowledge of Botany 

 that we had no intimation of, while they further demonstrate 

 that he possessed an interest in natural history at a much earlier 

 period in life than one would infer from a study of his ornitho- 

 logical publications alone. 



A far more interesting contribution to Cassin' s biography, 

 in-as-much as it corrects an error in our sketch of his life and 

 throws light upon his ancestry has been generously contributed 

 by my friend Frederic H. Shelton of Philadelphia and is pre- 

 sented herewith. — Wither Stone.
