2. After conception, women suffer throughout their whole body, and their sight becomes dim, and they are afflicted with headache. In some, these symptoms occur very soon, as early as the tenth day; in others they are delayed, in proportion as they have an abundance or deficiency of superfluous matter in their bodies. Nausea and vomiting often seize upon them, and on those especially in whom the purifications become stagnant, and do not yet fly to the mammæ. Some women suffer at the commencement of pregnancy, and others in the more advanced stages, when the fœtus begins to grow. Retention of urine also frequently attacks them at last. 3. Those that are pregnant with a male fœtus, usually pass through the time more easily, and retain a better colour throughout. If a female is conceived, the contrary is the case; for they are generally more discoloured, and suffer more during the period of gestation. In many cases the legs swell, and a swollen condition of the flesh is also common. In some women, however, the condition is contrary. Pregnant women are apt to have all sorts of fancies, which change very rapidly. Some persons call this longing. These fancies are strongest when a female is conceived, and there is but little pleasure in their gratification. In a few women the condition of the body is better during pregnancy; they suffer most when the hair of the fœtus begins to grow. Pregnant women lose the hair which grows on the parts that are hairy at birth, while it becomes more thick upon the parts on which it appears subsequent to birth. 4. A male fœtus usually moves more freely in the womb than a female, and the parturition is not so long. If a female, the parturition is slower. The pain in the birth of female children is continuous, and dull; in the birth of males it is sharp, and far more severe. Those who, before parturition, have sexual intercourse, suffer less in the process. Sometimes women seem to suffer, not from any pain of their own, but from the turning of the head of the child; and this appears to be the commencement of the pain. Other animals have a single exact period for parturition, for one time is appointed for them all. The human subject alone varies in this particular, for the period of gestation is seven, eight, or nine months, or ten at the outside, though some have even advanced as far as the eleventh month.
