  • Interesting fact: Baby donkeys or baby mules are also known as "Foals."
    • n mule A hybrid animal generated between the ass and the horse. The cross is usually between a jackass and a mare, that between a stallion and a she-ass being called a hinny. The mule is a valuable product of artificial selection, in some respects superior to either parent, and is extensively bred in America (Kentucky, Missouri, Mexico, etc.), in Spain, in Poitou (France), etc. It retains to some extent the specific characters of the ass, in the comparatively large head, long ears, roached mane, slim tail, and narrow, pointed hoofs, but acquires much of the size, strength, and symmetry of the mare. The animal matures slowly, is very long-lived, little liable to disease, and able to do more work than a horse under hard treatment and poor fare. Being also very agile and surefooted, it is serviceable as a pack-animal in countries where a horse could scarcely be used. The mule is not less docile and intelligent than the horse, and its strength is, in proportion to its size, probably greater. Mules are ordinarily incapable of procreation, and such seems to be always the case with the jack; but instances of impregnation of the hinny by the male ass or by a stallion are not rare.

    • n mule In spinning, a machine invented by Samuel Crompton (completed 1779), in which the rovings are delivered from a series of sets of drawing-rollers to spindles placed on a carriage which travels away from the rollers while the thread is being twisted, and returns toward the rollers while the thread is being wound: so named because it was a combination of the drawing-rollers of Arkwright and the jenny of Hargreaves.
    • n mule In numismatics, a coin, token, or medal which, owing to mistake or caprice, consists of two obverse or two reverse types, or of which the obverse and reverse types are accidentally associated.

To Sparta and to Pitane.--
