OF MULES. 



[Frotn thefupplementary Volume.'] 



WE fhall retain the name of Mule to the 

 animal produced by the jack-afs and 

 mare ; and to that procreated between the horfe 

 and Ihe-afs, we fhall give the denomination of 

 bardeau. The differences which fubfifl: between 

 thefe two mongrel animals have never hitlierto 

 been marked by any author. Thele differences, 

 however, aflbrd the moft certain criterion for 

 diftinguiftiing the relative influence of males 

 and females in the produd of generation, A 

 comparifon of thefe two mules, and other mon- 

 grels proceeding from a mixture of different 

 fpecies, will give us more precife ideas concern- 

 ing this relative influence, than could be obtain- 

 ed by fimply comparing two individuals of the 

 fame fpecies.
