ACTIN0HYK08IS.

Ferroncito describes a tumor removed from the anterior part 
of the neck of a three-year old ox. This tumor had a wide^ 
undefined base, and weighed nearly three pounds. On section, 
it was found to be composed of shining connective tissue, encap- 
suling a sarcomatous mass, which contained small masses of the 
A ctinomyces. 
Johne alludes to an instance of actinomykoma on the right 
cheek of a young cow. It was isolated, the size of a hen’s egg, 
fungiform, and apparently sarcomatous; the skin over it was 
ulcerated. A test-section removed from it during the life of the 
animal, was found to contain granulation nodules within which 
were the Actinomycetes. Six months after this section was made 
the tumor had disappeared, and there was only at the posterior 
border of the jaw, between this and the parotid gland, a small^ 
spindle-shaped, characteristic Actinomyces tumor, and in the loose 
connective tissue between the upper and lower buccal glands 
were more yellow nodules, the size of a pea, each containing the 
fungus. The interesting feature in this case is the disappear¬ 
ance of the tumor without surgical treatment, it having only 
been dressed with sulph. cupri pulv. after the section had been 
made. 
Another instance Johne met with in a two-year-old heifer, 
which a round, fungoid, flesh-like tumor, about two inches in 
diameter, on the right cheek, near the angle of the mouth; it 
appeared to grow by an ill-defined pedicle from the muscles. 
The corresponding part of the buccal mucous membrane ap¬ 
peared to be healthy. On the surface of the growth were seen 
the characteristic yellow nodules, which proved it to be an acti- 
nomykosis tumor. Ou removal it was discovered to arise from 
the intermuscular tissue in the vicinity of the submucous connec¬ 
tive tissue. The wound healed by primary intention. 
Veterinary Surgeon Eckert, of Walhalben, had sent to Johne, 
amongst other specimens, a round, dense tumor, about three 
inches in diameter, which had been removed from the sub-cutis, 
immediately over the masseter muscle, at the angle of the lower 
jaw. At the upper part of the tumor, at an earlier period, was a
