    The apex of the heart generally pulsates between the cartilages of the fifth and the sixth left ribs, and sometimes between the cartilages of the fourth and fifth, at four or five centimetres,* or little more than an inch, from the left extremity of ‘he sternum; in women and children, it beats oftener between the fourth and fifth left ribs. The right auricle, which is situated before and to the right of the base of the heart, is partly con- cealed by the anterior border of the right lung ; _ but its appendix and a part of its body correspond immediately to the sternum, or, more strictly speaking, to the synchondro-sternal articulation of the third rib. The left auricle, which is situated behind and to the left of the base of the heart, is covered, as well as its appendix, by the anterior border of the left lung, and corresponds to the in- terval between the third and the fourth ribs. The vertical line through the synchondro-ster- nal articulations, divides the heart into two un- equal parts, leaving one-third on the right, and two-thirds on the left side. The portion of the heart situated to the right, contains the superior extre- mity of the right ventricle, and the right auricle ; that portion lying on the left side, contains the inferior part of the right ventricle, the left ventri- cle and auricle. The pericardium has a pyriform appearance; enlarged at its middle, and extending, especially to the left, it continues to contract more in propor- tion as it approaches the point where it is reflect- ed upon the large arteries which take their origin * Centimetre is a French measure, equal to 3937 of an inch, 2%
