ses, that they might be examined under a variety 
circumstances, and their true character more 
Sa tisfactorily ascertained. The materials thus 
^cumulated would never have taken any other 
f °rtn than papers to different societies, had it 
**°t been thought desirable to have a Cornish 
^Vina as perfect as the present state of our 
knowledge would allow. 
The importance of local Faunas is too gene- 
ra Uy allowed to require any advocacy now. 
the investigation of circumscribed localities, 
habits and economy of animated nature are 
^ore minutely observed and better understood 
S' an when studied in the mass. The same 
finals being found in different parts of the 
^orld, they are thus examined under such a 
Var iely of circumstances, that we become more 
'^tiruately acquainted with them. It should 
a Ways be remembered that neither Beasts, Birds, 
^* s hes, nor any other animals, are scattered 
^diseriminately through the earth, but are con- 
fir >ed in groups to particular zones of climate; 
ar *d nature beautifully adapts her productions 
*° the situations they are destined to occupy. 
The migration of animals, which has hitherto 
^ filed the researches of naturalists, will pro- 
^ably receive its elucidation from these local 
Agisters. If after repeated observation it be 
f<>u nd that certain creatures periodically visit 
leave certain regions, it seems the most
