EXTRACTS FROM GERMAN PATERS. 
cated 103° F.; lameness in each of the four limbs was recorded;, 
the bones being thickened, and painful upon manipulation, more 
so in the vicinity of the articulations. 
The treatment for arthritic rheumatism was commenced, but 
no assuaging of the pain, or improvement in locomotion was 
secured. After five weeks pneumonia complicated the case, 
and the animal was destroyed. The subcutaneous tissue of the 
anterior and posterior limbs was infiltrated and the bones them¬ 
selves uniformly thick and hard. Longitudinal sections of the 
shafts of the long bones exposed nothing abnormal except an 
infinitesimal quantity of calcareous particles in the marrow, 
which indicated osteomyelitis ossificans. 
On the contrary the external surface of these bones was 
uniformly covered with deposits of irregular elevation, which 
had commenced to ossify. The synovial membranes were 
practically intact; periarticular tissue, on the other hand, much 
more abundant than normal, consisting of round cells of various 
sizes, and large spindle-shaped cells. Stomach, intestines, 
spleen and liver normal. Upon the surface of the kidneys herds 
of gray white globules. In the posterior lobe of right lung a 
fluctuating tumor the size of one’s fist, which consisted of one 
central portion, and several smaller ones whose interior was 
more or less in fluid degeneration. The case was one, there¬ 
fore, of periostial sarcoma. 
Some years previous Dieckerhoff recorded a case of a horse 
belonging to the royal stables and affected with general sarcoma, 
involving all the bones of the skeleton. The growths or de¬ 
posits were all ossified, hence he designated it osteo-sarcoma.—

SARCOMA OF TESTICLE. 
For a period of two years a fifteen-year-old stallion had 
exhibited swelling of the left testicle. Lately the circumference 
of this growth perceptibly increased, until, when brought to us, 
it was very little if any smaller than a citron melon. By castra¬ 
tion the epididymis proved to be ten times its usual measure-
