The interstitial tissue surrounding consolidated lobules is often edematous; the lymphatics are distended with serum and contain a moderate number of lymphocytes and polynuclear leucocytes. Among the lungs which have been studied histologically, pneumococcus has been almost invariably associated with the lobular lesions which have just been described, whether hemorrhagic, leucocytic or fibrinous; the histologic changes accompanying infection of the lung with streptococcus will be described later. Pneumococcus has been cultivated from the consolidated lung and is found in section of the lung. B. influenzæ is found in cultures made from the bronchi. Table XXXVIII includes those instances in which the histology of the consolidated lung accords with the description given above.
