CIRCULATION OF THE BLOOD. 513 anism of a plug or valve, just as in the ease of the arterial orifices (see farther on), but without remarking the entire difference of structure which distinguishes the auriculo-ventricular valves from the semi-lunar valves of the aorta and of the pulmonary artery. This theory has be- come, up to a certain point, the property of Chauveau and Paivre, on account of the interesting experiments which they have so often made upon horses killed instantaneously by section of the bulb, and in which artificial respiration was kept up. ' If, under these circumstances, the finger is introduced into one of the auricles, and the auriculo-ventricular orifices explored, the tricuspid valves will, at the moment that the ventricles begin to contract, be felt to straighten, push their borders, and stretch in such a manner as to become convex, and form a concave dome above the ventricular cavity.' This method of proof does not always furnish. Fig. 209.— Diagram of the Auriculo- Ventricular Apparatus during Ventricular Systole, after Ktfss. (Bcaunis.) 1. During the first part of systole. 2.
