REPORTS OF CASES 
but at the coecal valve was a concretion about as big as a base 
ball, consisting of plates of calcareous matter, interspersed with 
a yellow granular debris, containing no nucleus, encapsulated by 
a zone of fibrous tissue about a quarter of an inch thick, and 
loosely adherent to the intestines, forming a veritable ball valve. 
This horse lost no flesh, and there was no marked symptoms 
save when first seen, and near the close of life Indeed, he looked 
so bright, that a casual observer would say there was nothing the 
matter with him. 
I may add that his troubles were complicated during the lat¬ 
ter days of life by perforation of the upper wall of the rectum by 
the nozzle of the syringe. 
No. 2.—On the 8th of August, I was requested by Mr. C. 0. 
Haley, of Newark, to go to Milburn, N. J., to make a post mor¬ 
tem examination on a horse. 
The animal had been driven to Summit on the 7th, and when 
returning; the driver noticed on nearing; Milburn that the horse 
was breathing hard. He succeeded in getting him into the hotel 
yard, got off his harness, the horse laid down, stretched out, and 
died. Post mortem showed a rupture of the diapliraghm admit¬ 
ting a portion of the stomach and intestines into the thoracic 
cavity. Part of this rupture was new, part old, the heart was 
large and showed intense inflammation in the right ventricle, the 
valves being the color and appearance of crimson velvet, the left 
ventricle showed no inflammation, but several black patches of 
extravasated blood under the endocardium, one very large at the 
apex of the largest fleshy column of the first order. The lungs 
were congested. My theory is that the inflammation of the right 
ventricle was due to the excessive work thrown on it by the diffi¬ 
culty in forcing the blood through the compressed lung. The 
stomach was in a condition of self digestion and showed a post 
mortem rupture.
