Pathology Delafield and Prudden. 



Pulmonary Tuberculosis Exudative Type with Large Cavities. 



The entire lung is solid from new-formed tubercle tissue and exudate which are both 

 largely in a condition of coagulation necrosis. 



The thickened trunks of the larger pulmonary vessels are exposed in the depths of 

 the ragged communicating cavities. 



This lung was hardened in alcohol without injection of the blood-vessels.
