REPORTS OF CASES.

Held post-mortem next morning. Heart was of a pink 
:olor, easily torn, with fibrin around the semi-lunar valves of 
he aorta. The liver was a putrid mass, very soft like jelly ; 
could press my finger right through its substance without 
esistance, with small nodules studded here and there on its 
urface. In the vicinity of the liver there was peritonitis; 
his no doubt was the cause of the abdominal pain, and the 
iver trouble the cause of the continued constipation. There 
vas no sign of jaundice at any time present. On cutting down 
ipon the exostoses on lower jaw bone they seemed quite hard; 
could not cut them. Both shoulder joints were ulcerated 
n patches on its surface. Anterior limbs and tendons seemed 
o me natural, swelling excepted. Coxo-femoral joints had a

■xcepted. On removing the soles of the hind feet I found a 
>reaking down of perforans and perforatus, fracture of both 
lavicular bones, disease of os pedis, and ulceration of the in- 
erior extremity of the os suffraginis. I then turned both 
ind feet over to Dr. Liautard, who had them boiled out, and 
old me 1 had a nice case of big head on hand.

Jpon removing the lungs and heart, the latter was noticed 
s being extraordinarily large. An examination revealed the

The cow had at some time in the past swallowed a wire 
ail, three inches in length. The nail had found its way 
ito the reticulum ; there it pierced the anterior wall in the
