 recording the services you have rendered me, not only in its 

 preparation and in that of the previous volumes published 

 under my authorship; but as the efficient Keeper of that 

 Herbarium and Library, upon the perfect order and scientific 

 arrangement of which the 'Botanical Magazine' is depen- 

 dent for whatever scientific merit it possesses. 



Ever affectionately yours,
