of 1828, and of two others which had then recently died, 
the succeeding pages offer delineations, descriptions, and 
- anecdotes. -Among so numerous a collection of inha- 
bitants, of such dissimilar habits, and brought together 
‘into one spot from such distant and various climes, some 
changes have almost necessarily taken place even while 
our work has been passing through the press; yet so

transferred to the Zoological Society; and the white 
antelope has also exchanged its habitation in' the Tower 
for the delightful Garden created by that Society in the 
Regent’s Park. 
With the exceptions which have just been enumerated

Their continuance there affords a test of the fidelity of 
our work which could not be applied to any production 
on zoology that has yet appeared in this country, nor, 
to an equal extent, in any other. As a visit to the 
Menagerie will enable the reader at once to compare 
our representations and descriptions with their living 
prototypes, the imperative necessity of scrupulous accu-
