The Plan of the Cabinet of Natural History, and the 
styls> of its execution, will he in strict rtccOrdai.ce wi h he 
prinuiph'S laid down in the original prospectus of Dr Larilner’s 
Cydupivdia, The object of I ho Editor and his associates will 
he, ( here stated, “ to present the science in a form which 
shall bo univcMilly intelligible ; to render it attractive to the 
general ro»de r , ycr at the same time to inculcate sound prin- 
ciple* ; and by transfusing through the nhulo work a philoso- 
phic spirit, nor only to stimulate the diffusion of knowledge, 
hut to raise the tone of the public mind, and to awaken a taste 
for the contemplation of the works of nature." 
The scries will consist of Zoology, Botany, Mineralogy, and 
Geology 
To Zoology will he devoted ahout fourteen volumes : this 
part i f the work has ecn prepared by Mr Swainsou, In ot» 
dor to render the treatises equally attractive to the general 
render, and to the philosophical zoologist, it is proposed tn de- 
vote one half of each treatise to a general survey of tile 'ob- 
ject to which it is specially appropriated. In this, the lead ng 
natural divisions will hr pointed out ; the most remarknlde fact* 
connected with their economy, uses, anil geographical distribu- 
tion will be stated ; ami those analogies distinctly noted by 
which they are represented in other divisions of nature. The 
Other half will contain a systematic classification, in which rhe 
larg r group*, and in most instances al the genera, will be ar- 
ranged according to the natural system. 
The whole series will be copiously illustrated and embellish- 
ed by wood- cuts engraved by Branstoo, from original drawings, 
prepared by the authors themselves and by Mr T Landseer, 
such drawing* being al . ost invariably made from nature. 
The billow me is a general outline of the distribution of the 
work in volumes.
