The heart is smaller than normal, relaxed, and flabby, its fibres easily broken, and a cut surface presents the yellowish aspect of fatty degeneration in certain parts, with occasional extravasations located in the cardiac walls. The valves of the heart are relaxed and illy adapted to accurate closure. In certain recent cases soft coagula or dark fluid blood, and in others firmly coagulated blood, are found in the cavities; in those which have been prolonged the blood is more likely to be found fluid and the coagula diffluent. The endocardium is often blotched to a greater or less extent by sanguineous imbibition. The pericardium often contains serum, and in the worst cases is inflamed, lacerable, and contains bloody effusions. The inner surface of the great vessels at the base of the heart is stained by imbibition. The respiratory organs are variously affected. The mucous membrane lining the nose, larynx, and trachea is generally pale and flecked with extravasations of a dark-red color; more or less frothy fluid, tinged with blood, is present in these passages, and occasionally oedema of the glottis is encountered. The lungs are, as a rule, infiltrated with a bloody serosity, particularly in those cases with renal complication, or with a fibrinous or bloody exudation. The posterior portions of the lobes often present evidences of hypostatic congestion, or even of gangrene, and in the latter case the tissue is easily friable and emits a disagreeable odor. Their surfaces are mottled with superficial discolored patches of varying size and outline. The lungs may, on the other hand, be found pale, {173} with empty collapsed vessels and with little or no effusion. The pleural cavities commonly contain a serous fluid, or, in rare cases, a copious effusion of blood. Traces of inflammation and discoloration by sanguineous staining are traceable on the pleural surfaces. The digestive organs furnish strongly marked lesions. The mouth presents the most constant scorbutic feature, a stomatitis in which the gums are infiltrated, spongy, livid, and the seat of fatty degeneration; the teeth are loosened or have already fallen out. The stomach and small intestines are thin-walled, and the mucous membrane is often softened, and in places ulcerated; similar changes have been noted in the solitary glands. Follicular ulceration of the large intestine occurs, with softening and infiltration of the mucous membrane. Hemorrhagic effusions into the mucous membrane, forming stippling, flecks, or patches, occur in various degrees along the whole extent of the alimentary canal. The pancreas is occasionally found softened and containing hemorrhagic effusions.
