splendid and interesting which has yet adorned the 
Naturalist's Library. 
The volume on the Natural History of Coleopte- 
rous Insects (Beetles), by the Ilev. James Duncan, 
joint-author of the Elite tnologia Edinensis, is also 
nearly ready for publication ; and the beauty, variety 
of forms, and number of the figures (upwards of 110 
insects being represented), together with the interest 
excited in their extraordinary history, must insure it 
a favourable reception. Our volumes on Mammalia 
and Ornithology, formed the first attempt at present- 
ing the public with so extensive a series of correct 
representations of animals, in a highly finished and 
coloured form, with their authentic histories, at bo 
cheap a rate ; and our Entomological volumes mil also 
be found to realize to the fullest extent the promises 
held out in the original Prospectus. The volume 
will be enriched by a Memoir and Portrait of John 
Ray, the father of Zoological Science in Britain. 
Volumes on the Natural History of Deer— of 
Dogs — of British Butterflies — of Fishes — Parrots, 
&c. — are also in forwardness, so that we may now 
safely anticipate regularity of publication for the fu- 
ture.
