The writer has found, however, that in certain herds that have been killed after the tuberculin test, thejprimary and only lung lesions were in the ventral and cephalic lobes. It is important to note that usually the bron- chial glands are also involved. When the pleurae are affected the lesions consist of nodules varying in size from that of a millet seed to a large pea, sprinkled more or less thickly on one or both of the visceral or parietal surfaces. These form Fig. 39. Plwloi::iapli of pleura slnncin<i small tuberculous nodules. the 'pearl disease' Pcrlsucht of the German and the 'grape disease' of the English writers.

Tuberculosis of the thoracic glands is very common and usually accompanies lesions in the lungs; but the lungs may be healthy and the glands involved. (See figures for location of glands.) The primary lesions may be and often are found in the lymphatic glands about the head.
