The veins and arteries proceed both from the hypogastrics and the spermatic vessels, of which I shall speak by and by; all these are inserted and terminated in the proper membrane of the womb. The arteries supply it with food for nourishment, which, being brought together in too great a quantity, sweats through the substance of it, and distils as it were a dew at the bottom of the cavity; from hence do proceed both the terms in ripe virgins, and the blood which nourisheth the embryo in enceinte women. The branches which issue from the spermatic vessels are inserted on each side of the bottom of the womb, and are much less than those which proceed from the hypogastrics, those being greater, and bedewing the whole substance of it. There are yet some other small vessels, which, arising the one from the other, are conducted to the internal orifice, and by these, those that are pregnant do purge away the superfluity of the terms, when they happen to have more than is used in the nourishment of the infant; by which means nature hath taken such care of the womb, that during its pregnancy it shall not be obliged to open itself for the passing away those excrementitious humours, which, should it be forced to do, might often endanger abortion. As touching the nerves, they proceed from the brain, which furnishes all the inner parts of the lower belly with them, which is the true reason it hath so great a sympathy with the stomach, which is likewise very considerably furnished from the same, part; so that the womb cannot be afflicted with any pain but the stomach is immediately sensible thereof, which is the cause of those loathings or frequent vomitings which happen to it.
