    organs contained in the cavity. The pericardium is a double fold of the pleura which surrounds the heart in the form of a completely enclosed sac. It is well to note thai the covering of all the organs lying in the thorax is one and the same mem- brane, notwithstanding the names it bears in each separate place (pulmonary pleura, costal pleura, mediastinal pleura and pericardium).' Hence diseases of the whole part will always be seen as diseases of one organ, and it is therefore difficult to distinguish between diseases of the covering (serous mem- brane) and the organ itself. (b) The abdominal cavity is separated from the thoracic cavity in front by the diaphragm; above, it is bordered by the vertebral column; on the sides and below by the abdominal muscles and the peritoneum ; posteriorly it reaches to the pelvic cavity. Thus it is not entirely enclosed as is the thorax, nor has it the complete bony framework. In the abdominal cavity lie the stomach, intestines, liver, pancreas, spleen, kidneys, a part of the urinary bladder and the uterus and ovary (in female animals), besides blood and lymph vessels and nerves. The abdominal cavity is likewise lined with a thin membrane (peritoneum), which completely covers all the organs except- ing the kidneys and the ovaries. The covering, however, is not so symmetrical and regular as in the thoracic cavity, but in certain places it is present in such masses as to form large folds which hang free in the abdominal cavity, or serve as supports. The omentum for example, is just such a fold, between both membranes of which lie vessels and nerves. In a similar ab- dominal fold which hangs to the vertebral column, are found the intestines. This fold is called the mesentery and contains in addition to blood and lymph vessels, the nerves and lymph glands of the intestines. Between these folds as well as be- tween the abdominal wall and the peritoneum is deposited more or less fat (mesentery fat, kidney fat), according to the condi- tion of the animal. (c) The pelvic cavity lies behind the abdominal cavity and is surrounded by the pelvis, the sacrum and the first coccygeal
