SIBIRIAN JERBOA. 
Pennant Quadr. p. 429. 
The Jerboa is remarkable for the ftrange difpropor- 
tion between the length of the fore legs and the hind 
ones ; the former being fo very fhort as to be of no ufe 
to the animal in walking, while the latter are fo long as 
to equal the whole body. In confequence of this pe¬ 
culiar formation, the creature hands and reds on its 
hind legs only, and makes no other ufe of the fore legs 
than to hold its food, and draw down the hems of 
wheat and other vegetables on which it feeds, and to 
fcratch the ground in order to form its burrows. It 
has the general actions and attitudes of a bird, and the 
legs are covered thinly with fliort hair, and very much 
refemble thole of birds. The tail is very long and ter¬ 
minates in a tuft.
