nature as to necessitate the death of three of the patients 
within a period of fourteen days. The inflammation in each 
case embraced either two or three quadrants of the udder, 
in spite of careful and energetic treatment, which included 
deep incisions, only four of the animals were saved. In not a 
single case was recovery complete, since induration with sub- 
sequent abscess formation remained. 
The foot and mouth disease took a more malignant course 
in this stable than in two others directly adjacent. Infectious 
abortion had been known in this same stable for fifteen years. 
From th e foregoing we are led to believe that the apartment

fact, a drain of fair dimensions was discovered under the stalls 
and separated from them by means of a stone slab ; stable was

ETIOLOGY OF ACTINOMYCOSIS. 
Prof. Growitz demonstrated, before the physician’s club 
of Gnefwold, a preparation from the jaw of a calf which had 
died of actinomycosis. In sawing- through the osseous struc¬ 
ture and granulations, which filled the cavities of the bone, he 
discovered several long grains of corn. It is highly probable 
that the fungus or actinomycesdrus secured entrance through 
the laceration due to the corn. 
DANGER IN FEEDING DECAYED POTATOES. 
A farmer who had for the first time given his cows specked 
potatoes partially cooked by scalding water discovered short¬ 
ly afterward one of the animals suffering greatly from a dysp- 
noas induced by tympanites. 
The pausen was immediately punctured, but so violent 
was the fermentation that a second incision seemed advisable 
whereupon the contents spurted forth upon the ground and 
a so fell into the abdominal cavity, threatening peritonitis. In 
view of the liability to this complication the animal was de-
