APPENDIX. 
THE POTO ROO, or KANGAROO RAT, 
The head is flat fldeways, but not fo much fo as the true 
Scalpris Dentata. The ears are neither long nor fhort, but 
jnuch like thofe of a moufe in proportion to the fize of the 
animal. 
The fore legs are fhort in comparifon to tlie hind. There 
are four toes on the fore feet, the two middle are long, and 
nearly of equal lengths, with long narrow nails, flightly bent; 
the two flde toes are fhort, and nearly equal in flze, but the 
outer rather the largeft. From the nails on the two middle 
toes, one would fuppofe that the animal burrowed. Their 
hind legs are long, and it is in their power to ftand either on 
the whole foot, or on the toes only. 
On the hind legs are three toes, the middle one large, and 
the two flde ones ihort. The tail is long. The hair on the 
body is rather thin ; it is of two kinds, a fur, and a long 
hair, which lafl: becomes exterior from its length. The fur 
is the fineftj and is compofed of ferpentine hairs ; the long 
hai r is fironger, and is alfo ferpentine, for more than two 
thirds
