A CASE OF GENERALIZED TUBERCULOSIS IN A HEN. 
By E. Henry. 
This case is published as an illustration of the possibility of 
the existence of tuberculosis in birds. 
Symptoms. —Excessively lean condition ; bones protruding 
through the skin in some parts of the body ; comb of normal 
color and condition ; eye dull and partly closed by the membrana 
nietitans ; excessive weakness ; feathers nearly falling off; a large 
tumor under the abdomen. 
Post-mortem. —The tumor visible externally extended in the 
abdomen. It was twice as large as a hen’s egg, tuberculous in its 
nature, and adherent to the terminal portion of the intestines. 
Its centre had undergone granulo-fatty degeneration, and con¬ 
tained a leaden-colored liquid of an offensive odor. The tumor 
was formed of smaller ones, tuberculous. The intestinal glands 
were tuberculous, and of various sizes. Near the kidney there 
was another large growth. The liver was full of tubercles ; the 
gall bladder also full. The lungs were a mass of tubercles, in a 
state of mortification. The heart was small, flabby and pale; the 
pericardium free from serosity. The peritoneum was slightly 
infiltrated, especially where the large tuberculous tumors were 
situated.— Ibid.
