    III. THE LUNGS. Variola vera (a) severe. — In the cases fatal during the first week broncho-pneumonia (macroscopic) was ob- served twice, edema three times, and atelectasis with acute bronchitis once. In the cases grouped within the lethal period, the following pulmonary conditions occurred with the frequency indicated: edema (6), acute bronchitis (i), atelectasis and broncho-pneumonia (3), broncho-pneumonia (4), atelectasis (4), lobar pneumonia (2), peribronchial tuberculosis (1), broncho-pneumonia with multiple abscesses (i), atelectasis and edema (i), atelectasis and abscess (i), subpleural ecchymoses (i). In one instance a vesicular elevation in the mucosa of a bronchus was observed.^ In the later stages of the disease, constituting fatal com- plications, were seen pleurisy, broncho-pneumonia, and gangrene. Variola vera (b) with hemorrhage, — In one instance the mucosa of the bronchi showed small, indefinite, pale yellow, slightly elevated areas. Variolapustulosa hemorrhagica. — Among the cases of this group occurred broncho-pneumonia (i), edema (i), sub- pleural punctate hemorrhages (2), edema of the bronchial mucosa (2), occasional diffuse hemorrhages into the bronchial mucous membrane (i). Purpura variolosa. — In this form of the disease the lungs showsub-pleural punctate hemorrhages and moderate edema, with some reddening of the bronchial mucosa. IV. THE LIVER. In every type of variola the liver may be somewhat increased in weight; in some instances this condition is well marked. Variola vera. — In the uncomplicated form of the disease cases fatal during the first week present either no changes in 1 Microscopic examination showed this to be an elevation of the epithelium caused by exudation, and not a specific lesion.
