How Embryos are Nourished, or How the Infant in the Belly Receives its Aliment.

Democritus and Epicurus say, that the embryos in the womb receive their aliment by the mouth, for we perceive, as soon as ever the infant is born, it applies its mouth to the breast; in the wombs of women (our understanding concludes) there are little dugs, and the embryos have small mouths by which they receive their nutriment. The Stoics, that by the secundines and navel they partake of aliment, and therefore the midwife instantly after their birth ties the navel, and opens the infant's mouth, that it may receive another sort of aliment. Alcmaeon, that they receive their nourishment from every part of the body; as a sponge sucks in water.
