Fig. i. Cyanosis of head and neck.
Fig. ii. Acute tracheitis with desquamation of epithelium and
superficial necrosis.
Fig. iii. Acute serous and hemorrhagic pneumonia.
Fig. iv. Acute serous pneumonia with massive hemorrhage.
Fig. v. Acute hemorrhagic and purulent lobular pneumonia. The
purulent process is seen to be advancing from the focal
type to the more diffuse lobar by fusion of the
neighboring lobules.
Fig. vi. Acute purulent pneumonia.
Fig. vii. Lobular fibrosing pneumonia. In this specimen the patches of
new scar tissue formed irregular islands. The final stage
of contraction of the scar had not taken place.
Fig. viii. Acute serous pneumonia with some infiltration by mononuclear
cells.
Fig. ix. Acute hemorrhagic pneumonia.
Fig. x. Hyaline deposits upon alveolar walls. In some areas the wall
itself has suffered necrosis.
Fig. xi. Acute purulent pneumonia. In other areas of the same lung
the interstitial infiltration by leucocytes was more
intense.
Fig. xii. Acute lymph adenitis, showing the unusual numbers of
endothelial cells while leucocytes are relatively
infrequent.
Fig. xiii. Rupture of abdominal rectus muscle with hemorrhage. The
degeneration antecedent to the rupture is shown in the
belly of the muscle.
