There is a single dia-phragm, &, and a large liver, ef, common to both,lying in the mesial line, and over which thetwo peritoneal coatings are reflected, one over each half, formingalso its suspensory ligament in the mesial line above, and the septumbetween the two abdominal cavities by their union below.
