PLATE I. Represents the section of upper lobe of left lung in Case 348, extensively
affected with the acute form of the diffused tuberculation, degenerated into a chro-
nic form, and displaying numerous excavations. One near the apex contained
blood, and two vessels, under which a probe has been passed, are seen to cross from
one wall to the other, the canals of which were quite pervious. The bronchial
tubes entering cavities are much reddened.
PLATE II. Perforation of the pleura followed by acute fatal pleurisy occurring in
Case 361. A probe has been passed from the bronchial tube behind through the
superficial cavity into the perforation, which was of an oval form, and situated
about the middle of the upper lobe. The lung (the left) is much compressed, and
covered with a thick coating of yellow lymph.
