DISEASES OF POULTRY. 135 



These develop either in the peritoneum or in the tissue 

 of the liver and spleen. Rupture of the liver with 

 fatal bleeding is said to be sometimes observed in cage 

 birds affected with tuberculosis. The disease is of 

 the same nature as tuberculosis of the lungs, and is 

 treated at length in another chapter. As the disease 

 is incurable, no treatment is recommended, beyond the 

 sanitary measures for the eradication of the contagion 

 mentioned in the general article upon this subject.
