ACTINOMYCOSIS 263 The lymphatics show no constant tendency to become involved. Metastasis occurs in a very small proportion of the cases. When it does, as reported by Ponfick, large areas may be simultaneously aflfected. He reports a case in the human subject in which the left jugular vein was perforated by a mass of the organisms resulting in the formation of actinomycotic infarcts in the lungs, spleen, brain, and heart. In cattle, actinomycosis usually appears in one or more of the following locations. In the maxillary hones. Here it generally results in large tumor- like growths. Actinomycosis of the jaw usually commences with.

From the maxillary bone the disease may advance either to the sub- cutaneous connective tissue and the skin or to the oral cavity in the direction of the molar teeth, which become displaced. In the tongue. When the lesions appear in this organ the disease takes the form of an indurating glossitis. The tongue becomes thickly sprinkled with round or oval, hard, fibrous nodules which finally become purulent or chalky at the center. Around these there is a considerable increase of connective tissue which leads to the atrophy of the muscle fibers. Upon section the tongue is found to be.
