ANNUAL REPORT. OF THE 



Off. Doc. 



Necropsy : W('i<>ht 415 ])()ui)ds; poor condition. Both tbo auterior 

 and biddle lobos of the right lung are attached to the chest wall; 

 the anterior lobe is also attached to the i)ericardiiini. There are 

 nnnieroiis tuberculosis areas of all ages and up to one and a half 

 inches in diameter scattered rather thickly through both lungs. Both 

 bronchial and the mediastinal glands are enlarged and contain nu- 

 merous caseous and caseocalcareous nodules.

JV^ernpsy : Weight 48U pounds; fair condition. This bull was ap- 

 parently quite healthy on the 12th of September, and was found 

 dead in the stable the next day. It was found that there was a great 

 collection of gas in the paunch and this appears to have been the 

 cause of death, through interference with respiration by pressure 

 upon the diaphragm. The evidence of tuberculosis in this animal 

 consisted in the presence of several caseous nodules in both bron- 

 chial glands; the posterior mediastinal gland is six inches long and 

 quite thick. The entire structure of this gland has undergone degen 

 eration. Both postpharyngeal lymphatic glands are slightly enlarged 

 and contain caseous areas. 



It is quite possible that in this case the enlarged mediastinal lym- 

 phatic gland was a contributing cause of death through pressing upon 

 the oesophagus and tending to interfere with the regurgitation of 

 gas.
