    Begion of the Cavity of tlie Thorax. As this region can scarcely be considered as witliin the province of surgical anatomy, it is proposed there- fore to allude to it as shortly as possible. Its prac- tical bearing's to the surgeon seem rather to be upon the relations of the contents to the parietes, which have been already discussed, both as far as physical diagnosis and injury are concerned; and considera- tions with respect to aneurism of the aorta or its great trunks are subjects rather for systematic sur- gery. Since operative proceedings on the oesophagus, trachea, or great vessels are instituted in the neck, the chief anatomical bearings of these structures will be found described in the chapter on the Surgical Anatomy of the Neck. The cavity of the thorax is most conveniently de- scribed for reference as divisible into two pleural cavi- ties, separated in the lower four-fifths of the chest, by the three mediastina, and in the upper fifth by the great vessels springing from the arch of the aorta, a region called by Professor Wood, the ccrvico-thoracic. The posterior wall of this division, he makes the three upper dorsal vertebree and their intervertebral sub- stances, and the intervertebral substance between the third and fourth the anterior—the manubrium sterni, and upper fourth or fifth of the anterior mediastinum; on eitlaer side the apices of the lungs and pleurte. The anterior mediastinum is bounded as follows:— Anteriorly, by the sternum and left costal cartilages; posteriorly, by the pericardium, for the lower three- fourths or four-fifths, and for the rest, by the cer- vico-thoracic region; laterally, by the pleura.
