 neral mention of the beft authors thereon. 



After this, our author proceeds to the eftablifhment 

 of the natural characters of each order of the clafs 

 refpe6lively. Thefe alfo we muft omit, as incon-

 and more efpecially the latter claffes of this king- 

 dom, where the fubjedls are fo numerous : but

The Mammalia are divided by our author into 

 feven orders the diftinClions of which are, in this 

 artificial arrangement, principally eftabliflied on
