‘COLOURED FIGURES 
OF THE 
3IRDS OF THE BRITISH ISLANDS, 
Issued by LORD ‘LILFORD, F.Z.S., é&e. 
PRESIDENT OF THE BRITISH ORNITHOLOGISTS’ UNION. 
The want of a series of aburatel pinlonted illustrations of British Birds, 
‘in a handy form, has long been felt. Of the works specially devoted to this 
subject, that of Gould is too bulky and too costly to be available to a large 
number of the lovers of Ornithology; and Dresser’s ‘ Birds of Kurope,’ on the ~ 
other hand, covers a much larger field. The text-books of Macgillivray, Yarrell, 
and others are unaccompanied by illustrations such as I propose to issue; 
I think, therefore, that such illustrations cannot fail to form a useful companion | 
to the recognised text-books on British Birds. . 
The size of the work will be Royal Octavo, and it will be issued in Parts o 
twelve Plates each; it is calculated that 32 such Parts will complete the work, 
the price of each Part being 9s. 6d. As no separate Parts will be sold, Sub- 
scribers are expected to continue their subscription till the work is completed. 
All further particulars can be obtained from R. H. Porrer, British Ornithologists 
Union, 6, Tenterden Street, London, W. 
The following is a most important work, no expense being spared 
in its production.
