Ass is sometimes found of yellowish white, without any cross, in 

 its domesticated state. Mr. Cross informs me, that a year or two 

 ago, a specimen said to be of this species was brought to this coun- 

 try. 



This family (which is distinguished from all other animals by 

 its undivided hoof, formed of the two anterior toes, soldered to- 

 gether, its simple stomach, and its female having the teat placed on 

 the pubes,*) may be divided into two very distinct types of form ; 

 the one the Asses and Zebras, which are always whitish and more 

 or less banded with blackish brown, and always have a distinct 

 dorsal line, the tail only bristly at the end, and have warts only 

 on the arms, and none on the hind logs ; and the true Horses, 

 which are not banded, have no dorsal line, are furnished with 

 warts+ on their arms and legs, and have long hair on the tail, from 

 its insertion to its extremity.

 he ought to have said mares mammas prepuciales habent.
