The adhesion is obtained by the same formation of loose connec- tive tissue and loss of surface epithehum as occurs in the elephant. That respiration is not impeded l)y simple obliteration of the pleural cavity is evident in view of the fact that recent complete ad- hesion of lung to surrounding structures may occur in man without exhibiting clinically any respiratory symptoms revealing its presence.

This does not, of course, refer to a chronic pleurisy of some standing. The partial absence of pleural cavity in birds is not comparable to the absence in proboscideans because of the entirely different respiratory mechanism of the avian lung and air sacs. It is possible that the absence of intra-pulmonary bronchial cartilages in the elephant is connected with the absence of pleural cavity in some such manner as has been already suggested. On the.
