places the small tumors had become confluent to form irregular, 
compact masses, about twenty ufillimeters long, of a pale-red 
tint, and in which the yellowish-red centres or kernels were 
visible. Some of the tumors stood out from the mucous mem¬ 
brane like pin-heads. In the middle of the oesophagus was a 
similarly shaped potypus, from eight to nine millimeters in diam¬ 
eter at its base on the mucous membrane. The tissue of these 
masses was yellowish-red, soft, and filled with numbers of nodules 
containing the Actinomyces, f 
A ctinomykosis of the Stomach and Intestinal Canal. 
Two specimens of the disease in the stomach and intestines 
are described by Johne. In the second compartment of the 
stomach of an ox was found a round, flat tumor, the size of a 
fist, attached to its surface, and covered by normal ifiucous mem¬ 
brane. Its interior was soft, more or less spongy, and contained 
numerous small masses of nodules, consisting of conglomerations 
of the Actinomyces. 
Bollinger alludes to what was described as a tuberculous ulcer 
in the rumen of a cow, but which he is of opinion was a case of 
actinomykosis. 
Perroncito has described a sarcoma of the intestines and 
stomach, in which the fungus was found. 
Actinomykosis of the Udder. 
Johne has described two instances, and Ponfick one, of the 
disease occurring in the udder. Two were in swine, and one 
was due to experimental inoculation. In Jolme’s cases—acci¬ 
dental and experimental—the disease appeared as a diffused 
fibroma. In the accidental case, the udder was enormously en¬ 
larged, and weighed nearly sixteen pounds ; it was hard, indefinite 
in mass, and on section appeared to be, from its white color, a 
t An analogous instance, but the real nature of which was not suspected, is 
given in the Edinburgh Veterinary Review (vol. 4, p. 235), under the heading, 
“ Degeneration of the Mucous Membrane of the (Esophagus.” The membrane 
was studded with what was described as warty growths, some of them of great 
size.
