PREFACE 



THE SECOND EDITION. 



When the Arboretum Britannicum was first published it appeared in 

 Numbers ; and, as all the trees were drawn from nature, they were published 

 as they could be obtained, blanks being left for those of which good speci- 

 mens could not be found. These blanks were afterwards, in most cases, 

 filled up ; but sometimes it was discovered that different names had been 

 given to the same plant, and consequently that there was only one tree to 

 fill up the spaces that had been left for two names ; while, in other cases, the 

 same tree was found so different at different periods of its growth, as to 

 render two or more plates of it desirable. These circumstances occasioned 

 many inaccuracies in the plates, which were noticed in the errata ; but 

 shortly previous to Mr. Loudon's death he had all these faults corrected, 

 preparatory to a new impression of the plates being printed off; and it is 

 this corrected edition that is now offered to the public.
