iSo TRAVELS IN UPPER

 the contrary, that M. Pallas has frequently seen 

 his mus sagittti) the jerbo, in the sandy hills, &c. 

 Now, I should be glad to know,, how it was possi-

 long, in subterraneous galleries ? 



Besides, I never meant to assert that the jerbo

 when he has left it. This is a relation which the 

 jerbo would have with many other quadrupeds 

 which seek for the means of subsistence, and en-
