Sometimes the inflam- mation is confined to the tendons of the muscles which bend the leg (flexor tendons), and very commonly it attacks the coverings of the muscles of the thoracic walls. If the affected tissues be pressed upon, the animal manifests considerable pain, the muscles being very tender. There is a special tendency of the rheumatic inflammation in one joint to disappear somewhat suddenly and appear in another joint. This tendency on the part of the inflammation to shift thus, is spoken of as " metastasis.'''' The internal lining mem-. Fig. 42. The above picture (after Armatage) well shows the appearance presented by an ©x suffering from the malady known as rheumatism. The left hind-leg is seen to be kept so situated that it may as far as possible remain perfectly at rest, this near hind-leg being specially the seat of pain. The countenance of the animal is downcast and expressive of resigned suffering, and the illustration is altogether designed to depict that special kind of helplessness to move without causing great pain, which is one of the most marked characteristics of acute rheumatism. brane of the heart {endocardium) and the external membrane or sac {pericardium) in which it is enclosed, are sometimes attacked by the rheumatic inflammation, and the valves thus become involved in the disease. After the rheumatism is cured, the valves of the heart often remain permanently diseased, and in this manner most cases of heart aff"ection have their origin in the ox. In some instances so severe is the inflammation of the lining membrane inside the heart that the^animal succumbs during the acute stage of the rheumatism. When the valves of the heart are affected, or when anv struc- ture of the heart becomes involved, the pulse assumes a diffe- rent character. As a rule, in such cases it beco
