    more laterally they would implicate the lung-s; the position of the trunk and branches of the internal mammary render penetrating- wounds of the inferior intercostal spaces near the sternum very serious. A wound penetrating- the sternum, on a line with the nipple, and striking- upon the vertebra at right ang-les with the axis of the body, would traverse three cavities of the heart, two ventricles, and the left auricle. If an instrument traversed the lower intercostal spaces during- inspiration, it would wound the base of the lung-, the diaphragm, and corresponding- abdominal viscera, but during- expiration would avoid the lung-. Spinal region of thorax.—The posterior wall of the thorax is formed by the dorsal spine and its coverings, and is represented by a region bounded superiorly by the first, and inferiorly by the last dorsal vertebra, and laterallv bv the ano-les of the ribs. The integ-ument is very thick and dense, and con- tains a quantity of sebaceous follicles; the subcu- taneous cellular tissue is intimately united to the spinous processes of the dorsal vertebra (which can be plainly felt throughout the reg-ion), thus preventing fluid infiltrating or pus appearing- superficially, except along- the sides of these pi'ocesses. The dorsal apo- neurosis invests the anterior and posterior surfaces of the trapezius and latissimus dorsi, uniting- superiorly ith the cervical, and inferiorly with the lumbar apo- ■ urosis, sjjlitting to enclose the serrati postici; it is rached to the spinous processes of the dorsal ver- brje and tubercles of the ribs, enclosing- all the muscles of the back, and separating- the superficial from the deep layer. The first layer of muscles con- : sists of the lower part of the trajjezius and the latis-
