The whole organ, with about two inches of thegreat blood-vessels which arise from it, is enveloped in afibrous sac known as the pericardium.1 This sac is linedwith a smooth, glistening membrane, which secretes alubricating fluid called serum, thus permitting the heartto move freely and without friction.
