Very greatly enlarged lymjDli glands may interrupt the functions of neighboring organs; thus enlargement of the glands of the throat may interfere with deglutition or respiration while that of the glands of the axillary region and the groin occasionally produces riy. 87. Tulicvc'ulofiis of the subuiaxilluiy, jirescapular and inguinal lyni|)h glands. Tuberculosis of the udder begins with a rather diffuse pain- less induration of one or ))oth posterior quarters without local hyperthermia. The process occasionally spreads to the adja- cent quarters and gradually develops into an exceedingly^ hard and nodular tumor which may approach the size of a child's head and cause atrophy of the remaining parts of the gland (Bang, Fig. 88). In other instances we may observe, especially after the udder has been milked dry, several nodules, or larger nodes in the otherwise uniformly elastic glandular tissue of one or more quarters of this organ. These tumors are firm, painless, do not show an increased temperature and may exist singly or as a conglomerate mass with nodular surface, affect- ing a part of or an entire quarter. This may cause the teats on one side of the udder to assume an irregular direction and.
