The importance of the lymphatics in the inflammatory lesions of parenchymatous organs is well recognized. They are not only frequent carriers of infection, but in the absorption of inflammatory products their condition becomes a paramount issue in the ultimate fate of the organs.
We know that in pneumonia, for instance, the state of the lymphatics determines the resorption of the exudate and, therefore, the termination of the whole disease. Obliteration of the lymphatics by an acute lymphangitis and perilymphangitis retards the resolution until these paths have been cleared, and, if this does not take place, aids the termination into gangrene or abscess. Again, permanent destruction of lymphatics, as in chronic essential emphysema and in senile atrophy of the lung, are grave factors against rapid removal of inflammatory exudates and are almost entirely responsible for the long-continued, irregular course often taken by inflammations of the lungs, as well as
