A glance at the annexed diagram (Fig. 177) will show this. The diagram, carefully reproduced from an anatomical preparation of an animal which succumbed to pericarditis, shows that the distended pericardium extends close to the neck of the xiphoid cartilage. First stage. Identify the three following anatomical guiding points-:— (1.) Xiphoid appendix and white line. (2.) Point at which the circle of.
