    granulations, more numerous, perhaps, than in any other tissue. Sometimes old lesions of the ribs, the bodies of the vertebrae, the sternum, the articular extremities of the long bones, etc., are met with. These old lesions take the form either of yellowish-white, fairly firm, rounded nodosities of the size of a pea or a walnut, or of a grayish or yellowish caseous infiltration. The lesions are developed in the spongy tissue, and the com- pact tissue in their neighbourhood seems to be irritated, is increased in thickness, and often is also covered with a more or less thick and even layer of subperiosteal young bony tissue. Sometimes, lastly, the tuberculous growths soften and produce fistulse and eruption of the caseous contents, either externally or into the neighbouring joint. In the udder the initial lesion generally assumes the form of a slowly-progressive sclerosis. The interlobular connective tissue, normally so scanty, becomes gradually thickened and fibrous, and can be seen to be infiltrated by minute miliary granulations, which are gray, or yellow and caseous, and scattered here and there in varying numbers. At a later stage these granulations are larger and more numerous, and become softened or calcified. The glandular tissue is, as it were, smothered by the hypertrophy and fibrous transformation of the interstitial connective tissue. The large excretory ducts are here and there dilated by masses of yellow caseous material, which is very rich in bacilli, and the walls of the ducts are thickened, fibrous and sacculated, and sometimes infiltrated by minute yellowish granulations. Tuberculous lesions of the testicles are very rare, but they may occur in the form of fibrous nodules, about as big as a hazel-nut or an almond, or else in the form of yellow, calcified or softened miliary nodules.
