Rollin asserts that the common mule from the ass and horse is particularly apt to have bars on its legs; according to Mr. Gosse, in certain parts of the United States, about nine out of ten mules have striped legs.

I once saw a mule with its legs so much striped that any one might have thought that it was a hybrid zebra; and Mr. W.

C.

Martin, in his excellent treatise on the horse, has given a figure of a similar mule.

In four coloured drawings, which I have seen, of hybrids between the ass and zebra, the legs were much more plainly barred than the rest of the body; and in one of them there was a double shoulder-stripe.
