ADDRESS. 
The Natural History of Mammalia is intended lo embrace an 
account of the structure ami habit* of nil the known specie* of 
Quadrupeds, or Mammals; to which will be added observations 
upon their geographical distribution and classification. Since the 
fossil and recent species illustrate each other, it is also intended to 
include notices of the lending characters of the Extinct Species. 
The genera, and many of the species, will be illustrated partly 
by engravings on steel, and partly by wood engravings; of the 
latter, between fifteen and sixteen hundred figures are executed. 
The modifications observable in the structure of the skulls, teeth, 
feet, and other parts, will be almost entirely illustrated by steel 
engravings. 
For various reasons it has been thought desirable in this work 
to follow the course usually adopted by comparative anatomists ; 
rh. to commence with the lowest species, and to trace through 
them to the highest, the various modifications of structure and 
functions. In the present case, one of the advantages arising 
from this mode of treating the subject is, that it will enable the 
author to lay before the public, at an early period, an account of 
some of the most interesting of modem discoveries amongst the 
Mammalian forms ; and, in accordance with this plan, he has 
commenced with the Marsupial animals. 
The work is issued in Monthly Parts, each containing three 
sheets of Letterpress and Engraved Plates, besides Woodcuts. 
Price, with the Plates coloured, 8s.; with the Plates plain, 
2s. Gd. each Part. 
The size of the woik corresponds with Dr. Prichard's Natural 
History of Man , to which it will form a suitable companion.
