PUBLISHER’S ADVERTISEMENT. 
In the absence from this country of the talented author 
of this volume, when the second edition was required, it be- 
came necessary to enquire for a competent editor. Mr. Barnes, 
of Levens, (to whose fame as a femist nothing can be added 
here) rendered great help to Mr. Linton in 1865, and now 
has, by the introduction of his elaborate and most valuable 
Tables of Varieties, put a finishing touch to the book which 
perhaps no other hand could have supplied. It will be 
appreciated by all concerned, and from me unbounded thanks 
are due. Not a little trouble has devolved upon collectors who 
have supplied Mr. Barnes with the results of their labours ; 
and to all of them I am under great obligation.
