 \Vork which has been made particularly valuable to 

 our local situation by your additions, and as the public, 

 especially in this vicinity, are much indebted to your 

 . t |ectures and publications, for a knowledge of the 

 science of Botany, and an acquaintance with our native 

 productions, there is a peculiar propriety in my oflferirig 



lKyour notice. 

 mlP*^ 



As you are acquainted with the value of the science, 



as a branch of early education, I inn confident that 

 every effort to put into the hands of the young a facility 

 in its acquisition, will meet your approbation. 

 ^ "Permit me then to place the following pages unde"r 

 ycfur protection, and offer you this inscription as a 

 of personal gratitude and esteem for the 



ir and benefits of your friendship, which were 



f 

 bestowed on me white your pupil, and have 



een continued. 

 Touv much obliged friend and 



humble servant,
