    side by the left side, and vice versa the left auricle prevents itself fi'om being pushed to the left side by the right auricle; and the left ventricle while contracting, prevents the Heart from being push- ed into the chest, by the contraction of the right ventricle; and the right ventricle while contract- ing, prevents the left ventricle from pushing the Heart against the ribs. —Theaui'icles while filling with blood, assist the contraction of the ventricles, by pressing on them as they are distending with blood, and while they are contracting. The auricles v^hile filling, and distending with blood, press against the ventricles during their contraction, and assist them in con- tracting, and yet just as the ventricles are emp- tied, the action of the auricles caused by their going to contract, assists the dilatation of the ventricles. —The impulse of the apex, we consider, to be caused by the systole of the left auricle, and partly by the last act of the diastole of the left ventricle, when the left auricle is fully distended, the force of the beginning, or first act of contraction, elon- gates the auricle, at the pulmonary vein, or at its upper part, and closes the pulmonary orifice, and the apex is drawn up and back, and touches the ribs. The apex is also raised, by the expiring systole of the right ventricle, raising as it were the apex of the ventricle. —The reason why we have so many different, and
