It will not be forgotten that this membrane extends over the diaphragm, and that, in consequence of the lungs completely filling all the space (not occupi^ by other organs) during every position of the chest-walls, the costal and pulmonary pleural surfaces are in constant contact By far the greater part of the lung-substance consists of elastic tissue, thus adapting the principal respiratory organs to that amount^of distention and recoil to which they are ceaselessly subjected during the en- tire lifetime of the animal.
