    THE COW (continued). Infarcts in Spleen— The spleen may also be considerably enlarged as the result of the presence of numerous infarcts produced by emboli, which take their origin on the heart valves in cases of endocarditis. These infarcts show themselves as raised areas on the surface of the organ, at first red in colour, later becoming pale as the process of necrosis sets in. Rotation of Spleen— Occasionally the spleen becomes altered in shape as the result of rotation, particu- larly in swine, in which animal the organ is somewhat more loose than cattle. The result is an anaemia from twisting of the vessels which is, sooner or later, followed by shrinking and necrosis. Hsomatoma of Spleen— Every now and then a spleen is encount- ered which shows upon its surface a circular swelling varying in size from a marble to a cricket ball, dark red in colour, and of a soft consistency. When the swellings are cut they are found to contain blood, being caused by a local rupture of vessels at the spot. Parasites, Tumours, and Abscesses of Spleen - Certain parasites occur in the spleen, particularly echinococcus, and occasionally a liver fluke. Of the tumours which attack this organ, sarcomata and carcinomata both occur, generally as secondary growths. Abscesses are found in spleen, in cases of general pya3mia. It is not uncommon to find a spleen in an extremely fibrous or cirrhotic condition, especially in old animals.
