were complete. The surface of the lungs was mottled
with dark red and pale red areas. Fine petechiae
studded the lung surface. Raised areas of white
emphysematous lung tissue several millimetres in
diameter were found throughout both lungs but mainly
in the lower lobes. The left lower lobe felt firmer than
the other lobes. The lungs were inflated gently and it
was noted that the resulting expansion was not uniform.
Some segments of the lung expanded and became raised
nodules while other segments remained unexpanded
(Fig. 1). The over-all appearance was like a cirrhotic
liver. On section there was little congestion. There
were expanded aerated areas interposed by dull red solid
areas of lung tissue. No evidence of recent abscess
formation was noted.
