No. 4.] CATTLE COMMISSIONERS. 573 



Attached to the cephalic lobe of the left lung by a pedicle is a small, 

 flattish, smooth mass of new tissue. 



The pleural aspect of diaphragm and portions of the pericardium are 

 covered with areas of the highly vascular, neoplastic tissue. In some, 

 small nodules can be felt at the free extremity of this tissue. 



On the right ventricular surface of the heart four flattish pedicled 

 masses, about as large as split peas, are attached. 



The various lymph gland systems, ventral and dorsal mediastinal and 

 bronchial glands, do not show the presence of tubercles or any augmenta- 

 tion of size. 



No. 39 (sputum culture V.). — Cow about four years old. In utero 

 a foetus three to four months old. 



Development of vascular fringes along one border of ribs of the right 

 side of thorax, as in preceding case, but amount slight, compared with 

 that case. In the intercostal muscles at the point of inoculation a mass 

 of perhaps a dozen small, grayish tubercles. 



Right lung : In the large caudal lobe, in the same situation as pre- 

 ceding case, a projecting tumor about one inch in diameter When 

 incised it is found composed of two one-half inch foci of disintegrated 

 cheesy-viscid matter, enclosed in thin, smooth capsules. No sur- 

 rounding infiltration. 



Along the margin and on the caudal surface of this lobe slight devel- 

 opment of pendulous vascular tissue and a sessile tubercle about three- 

 sixteenths inch diameter. On the left caudal lobe only very slight 

 production of vascular tissue. 



On the surface of one of the middle dorsal mediastinal glands an 

 aggregation of minute tubercles one-half inch in diameter. Imbedded 

 in the cortex of the same gland two minute tubercles. 



No. 76 (sputum culture VI.).— In utero a fcetus about four 

 months old. 



Within the thorax, on the right side, between the seventh and eighth 

 ribs, is a small, pedicled, blackish (hemorrhagic) mass of firm tissue 

 about as large as a pumpkin seed, another on the tenth rib. On most 

 of the ribs behind the seventh are gelatinous-looking pendulous 

 vascular fringes of neoplastic tissue. On the pleural surface of the 

 diaphragm a similar development of vascular tissue and several firm 

 pedicled masses like those on ribs. 



Of the right lung the cephalic lobe shows very slight formation of 

 marginal fringes. In the ventral lobe, whose tip is adherent to the 

 pericardial fat, a uniformly grayish, sharply defined focus, one-quarter 

 inch in diameter. 



In the same situation as in the preceding cases the caudal lobe shows 

 a slightly projecting tumor, about one and three-quarters inches in 

 diameter externally. When incised it is found to consist of a smooth- 

 walled sac, one and one quarter inches diameter, containing a yellowish 

 curdy mass, together with a little turbid fluid. No siuTOunding infil- 

 tration. On the convex surface of this lobe there is a slight growth of 

 vascular tissue. Near the caudal tip a flattish mass, partly yellowish, 

 partly blackish, attached by loose tissue to the margin of the lobe.
