PREFACE. 
The fourth fedion of digitated quadrupeds con- 
fifts of thofe which are abfolutely deftitute of cutting 
teeth, fuch as the Sloth and Armadillo. 
The fifth fedion is formed of thofe which are k 
deftitute of teeth of every kind, fuch as the Manis 
and Ant-eater . 
The third and fourth orders, or divifions, are the 
Pinnated and the Winged Quadrupeds; the firft 
takes in the Walrus and the Seals, and (in confor¬ 
mity to preceding Writers) the Manati . But thofe 
that compofe this order are very imperfed : Their 
limbs ferve rather the ufe of fins than legs ; and 
their element being for the greateft part the v/ater, 
they feem as the links between the quadrupeds and 
the cetaceous animals. 
The Bats again are winged quadrupeds, and form 
the next gradation from this to the clafs of Birds ; 
and thefe two orders are the only additions I can 
boaft of adding in this Work. 
So far of Syftem •, die reft of my plan compre¬ 
hends numerous Synonyms of each Animal, a brief 
defcription, and as full an account of their place, 
manners, or ufes, as could be colleded from my 
ow r n obfervations, or the information of others *, from 
preceding Writers on the fubjed ^ from printed 
Voyages of the beft authorities, 'or from living 
Voyagers *• If it has the fortune to be any-ways 
* And it may be added, from the different Mufeums at home and 
abroad, particularly, from that matchlefs collection in the Britijb 
Mvjium , and, placed as it is under the direction of Gentlemen 
gs irmch d’ftinguifhed for their politenefs as their love of fcience, 
my 2c c? ' to its contents, has been rendered, at all lit times, fo eafy, 
as to "put this Work under lingular obligations to them.
