ears and the eyelids, for, although the rest of the body be all of one colour, the mule that is produced will have all the colours that are found in those parts. Mæcenas was the first person who had the young of the ass served up at his table;[1938] they were in those times much preferred to the onager or wild ass;[1939] but, since his time, the taste has gone out of fashion. An ass, after witnessing the death of another ass, survives it but a very short time only. CHAP. 69. (44.)—THE NATURE OF MULES,[1940] AND OF OTHER BEASTS OF BURDEN. From the union of the male ass and the mare a mule is produced in the thirteenth month, an animal remarkable for its strength in laborious work. We are told that, for this purpose, the mare ought not to be less than four years old, nor more than ten. It is said also that these two species will repulse each other, unless the male has been brought up, in its infancy, upon the milk of the other species; for which reason they take the foals away from the mare, in the dark, and substitute for them the male colts of the ass. A mule may also be produced from a horse and a female ass; but it can never be properly broken in, and is incorrigibly sluggish,[1941] being in all respects as slow as an old animal. If a mare has conceived by a horse, and is afterwards covered by an ass, the first conception is abortive; but this is not the case when the horse comes after the ass. It has been observed, that the female is in the best state for receiving the male in the seventh day after parturition, and that the males are best adapted for the purpose when they are fatigued.[1942] A female ass, which has not conceived before shedding what are called the milk-teeth, is considered to be barren; which is also looked upon as the case when a she-ass does not become pregnant after the first covering. The male which is produced from a horse and a female ass, was called by the ancients “hinnulus,” and that from an ass and a mare “mulus.”[1943] It has been observed that the animal which is thus produced by the union of the two species is of a third species, and does not resemble either of the parents; and that all animals produced in this way, of whatever kind they may be, are incapable of reproduction; she-mules are therefore barren. It is said, indeed, in our Annals, that they have frequently brought forth;[1944] but such cases must be looked upon only as prodigies.[1945] Theophrastus says that they commonly bring forth in Cappadocia; but that the animal of that country is of a peculiar species.[1946] The mule is prevented from kicking by frequently giving it wine to drink.[1947] It is said in the works of many of the Greek writers, that from the union of a mule with a mare, the dwarf mule is produced, which they call “ginnus.” From the union of the mare and the wild ass, when it has been domesticated, a mule is produced which is remarkably swift in running, and has extremely hard feet, and a thin
