In the fetal heart the Eusatchian valve is large. The foramen ovale which joins the two auricles gives a free communication between them until the middle of fetal life, at which time a valve grows from the posterior wall of the right auricle to the left of the foramen ovale, and prevents the blood from passing through except from right to left. In twenty per cenl of the cases the foramen ovale remains open
