The gestation period for a horse is eleven months, so this can't be Ed's foal.
Exact information in regard to the period of gestation of the female is still lacking, the length of the period being given from eighteen to twenty-two months by different authorities.
Whether a pouch is present or not, the young are born in an exceedingly imperfect state of development, after a very short period of gestation, and are immediately transferred by the female parent to the teats, where they remain firmly attached for a considerable time; the milk being injected into their mouths at intervals by means of a special muscle which compresses the glands.
In the case of the great grey kangaroo, for instance, the period of gestation is less than forty days, and the newly-born embryo, which is blind, naked, and unable to use its bud-like limbs, is little more than an inch in length.

It is a common terminology to call premature labour of an accidental type a "miscarriage," in order to distinguish "abortion" as a deliberately induced act, whether as a medical necessity by the accoucheur, or as a criminal proceeding (see Medical Jurisprudence); otherwise the term "abortion" would ordinarily be used when occurring before the eighth month of gestation, and "premature labour" subsequently.
As an accident of pregnancy, it is far from uncommon, although its relative frequency, as compared with that of completed gestation, has been very differently estimated by accoucheurs.
According to the weight of authority in the United States abortion was not regarded as a punishable offence at common law, if the abortion was produced with the consent of the mother prior to the time when she became quick with child; but the Supreme Courts of Pennsylvania and North Carolina held it a crime at common law, which might be committed as soon as gestation had begun (Mills v.
