[c] The Sea-Calf is said by the French Academists, to have this Provision, and their Account of it is this: Its Heart was round and flat. Its Ventricles appeared very large, and its Auricles small.——Underneath the great Aperture, through which the Trunk of the Vena Cava conveyed the Blood into the right Ventricle of the Heart, there was another, which penetrated into the Arteria Venosa, and from thence into the left Ventricle, and afterwards into the Aorta. This Hole called the Foramen Ovale in the Fœtus, make the Anastomisis, by the Means of which, the Blood goes from the Cava into the Aorta, without passing through the Lungs. French Anatomists, p. 124.
