of a jackass (male ass) and a mare ; and a hinny, that 

 of a stallion and a she-ass. Sometimes, the term, jennet, 

 is applied to a hinny, which is incorrect, because the word, 

 jennet (as used by Macaulay in his History of England'),

in breeding, we have the fact that no special distinction 

 as regards appearance or conformation can be made 

 between mules and hinnies, because, in both hybrids 

 the proportional resemblance to horse and ass is of infinite 

 variety. As mares are generally taller than she-asses ; 

 mules as a rule are of a greater height than hinnies, which 

 is the only difference between these two hybrids. 



Scientific research has amply proved that mules and 

 hinnies are absolutely sterile, although cases are on record 

 of induced lactation occurring in females of this kind.
