TO WILLIAM ROSCOE, ESQ., F.L. S, 



c^r. ^x. S,x. 



My dear Sir, 



In iledicatiug this Work to you, I am not presmnptuous 

 enough to believe that I can offer anything novel in a botanical 

 point of view, though I am sure you are too generous a patron of 

 the science to discourage any effort, however feeble, wliich has for 

 its object the diffusion of a taste for such pursuits: my motives, 

 however, are not of this natui-e ; I would offer it to you as a mark 

 of respect and affection, but more particularly of gratitude, for the 

 warm attachment you have ever evinced towards me, which has 

 contributed so much to the happiness of my life. With these sen- 

 timents, allow me to subscribe myself, 



Your affectionate Daughter, 



M. R.
