In the abdomen, a flattish, sessile mass of pinkish gray tissue, about 

 three-quarters of an inch in its longest diameter, attached to omentum * 



Of the three animals receiving bovine tubercle cultures, the fate 

 of one (young bull No. 71) has ah-eady been given. The two 

 other cases remained stationary in weight : — 



No. SS, original weight, 850 povmds ; weight at end of experiment, 

 850 poimds 



No. 63, original weight, 875 pounds ; weight at end of experiment, 970 

 pounds. 



The autopsy notes are in brief as follows : — 



No. 63 (bovine culture V.). — White cow, spotted with red. Horns 

 sawed oflf. Probably six years old. Foetus in utero, about two months 

 old. 



Thorax : Right lung adherent to chest wall in several places. At 

 point of inoculation, between seventh and eighth ribs, an excrescence, 

 about three-quarters inch in diameter, of dense, pearly-looking connec- 

 tive tissue, enclosing a disintregated mass. Numerous masses and 

 aggregations of small tubercles on all ribs ; these in some cases several 

 inches in length The left side of thoracic Avail, below the level of the 

 point of inoculation on the opposite side, is covered with a uniform, pink- 

 ish-gray deposit of verj- minute tubercles. Eruptions of tubercles on 

 pleural surface diaphragm and on pleural covering of dorsal mediasti- 

 nal space. 



On caudal lobe of right lung a considerable number of tubercular 

 masses, flattish, sessile, from one-eighth to three-quarters inch in diam- 

 eter. Between the cephalo-lateral border of this lobe and the pericar- 

 dium is a mass of newly-formed tissue, dense, in which are imbedded 

 many minute yellow tubercles and masses of pericardial fat. The whole 

 is about as large as a fist. It binds the lung tissue, pericardium and 

 diaphragm together. 



Many tubercles on the caudal surface of this same lobe. 



There is no distinct focus in this lobe, as a result of the injection, and 

 it is probable that much of the fluid was dejjosited in the pleural cavity. 

 But palpation reveals throughout both lungs small shot-like bodies, in 

 close proximity. On section numerous yellow tubercles from one-thirty- 

 second to one-sixteenth inch in diameter are found imbedded in the limg 

 tissue of all lobes. 



The dorsal mediastinal lymph glands are all several times normal 

 dimensions. They contain many coalescing yellow tvibercles. The 

 ventral (anterior) mediastinal glands are similarly enlarged, and the 

 cut surface shows a imiformly cheesy jjarenchyma. 



Minute grayish jioints under the capsule of the liver. 



* The character of these peculiar formations will be described in a subsequent 

 report.
