The nourishment of the body being first changed into corruption, that is, having lost its proper form, is absorbed into the substance of the limbs, and repairs their waste, passing through a medium into another form, and by the spontaneous motion of the parts is so separated, that such portions as are adapted for the purpose are taken up into the structure of this fair visible, while such as are unfit are rejected through their own passages. One part consisting of faeces is restored to earth to reappear again in new forms; another part goes off in perspiration; and another is taken up by the nervous system for the purposes of reproduction of the species.
