PREFACE. 
the six works I proposed, and have, moreover, what I did not at first contemplate, added a 
volume, which is the only existing work on British Wild Flowers. 
The first edition was stereotyped, and consequently no alteration or improvement could be 
made in it. The copyright having passed into other hands, the present and second edition 
of this important work is now issued. In it much new and valuable matter has been incor- 
porated, the vast amount of general knowledge lately accumulated has been carefully collated 
and added to its pages, former errors have been corrected, and, as it is hoped, an accurate 
and extensive view of the state of botanical science is presented to the public.
