whole of the materials collected from various and au- 
thentic sources. To Joun Baytey, Esq. F.R. and A.S. 
M.R.I. A. &c. he is indebted for several suggestions in 
addition to the information contained in that gentleman’s 
valuable work, “ The History and Antiquities of the 
Tower of London.” To Mr. Atrrep Cops, the present 
KEEPER OF THE Lions, whose meritorious exertions for 
the increase and improvement of the Menagerie have 
been already adverted to, he has also to tender his 
thanks and those of his coadjutors for the facilities con- 
stantly afforded to them in the most ready and obliging 
manner, and for much valuable information relative to 
the history and habits of the animals. 
But especially are his best thanks due for numerous 
suggestions and much valuable assistance to his friend 
N. A. Vicors, Esq. A.M. F.R. and L.8., the zealous 
and talented Secretary of the ZooLocicaL Society. 
To that distinguished zoologist, whose extensive and 
intimate acquaintance with the animal kingdom at large, 
and particularly with its feathered tribes, is universally 
acknowledged, and to other leading Members of the 
Society to which he devotes his talents and his time, 
a work like the present appeared not ill adapted to 
advance the good cause in which they are engaged, the 
diffusion of knowledge. Under their auspices it was 
commenced, by their countenance it has been fostered, 
and it is with the sanction of their approval that it is 
now submitted to the public eye. *
