same, with a slight variation of the temperature, which ranged 
from 105° F. to io6° F. The pulse also varied somewhat, from 
60 to 70 beats per minute. Respiration a little more dis¬ 
tressed. The animal gradually losing flesh and getting weaker 
from day to day. 
July 7.— On making an examination this morning, found 
(hat the action of the heart could be distinctly felt on the 
right side of the chest, and seems to be as plainly felt on the 
left side. 
When the horse was led out he swayed his body to the 
left, his head to the right; mucous membranes deathly pale; 
auscultation over the thoracic cavity revealed no abnormal 
sounds, but it was evident from the peculiarity of gait and the 
beating of the heart, that the difficulty was now of a cardiac 
nature. Temperature 105° F., pulse 70, respiration 25. 
The symptoms from now on were about the same, with oc¬ 
casional gradual variation, but at no time did the temperature 
fall below 105 2-5 0 F. 
The horse gradually failed until August 13, when there 
was a marked change in the pulse, it becoming accelerated, 
weak and almost imperceplible. The horse refused to move 
unless urged. The thoracic cavity was beginning to fill. He 
grew weaker rapidly, and died without a struggle on the 
morning of August 15, after an illness of fifty-eight days. 
Post-mortem .—On opening the chest it was found filled with 
an amber-colored fluid of the consistency of water. Lungs 
normal in appearance, both as regards size and color; they 
were slightly displaced owing to the size of the heart. The 
pericardium was attached to the pleural walls on the left side 
of the chest and filled with a fluid similar to that contained 
in the thoracic cavity. 
The inner surface of the pericardium was attached to the 
heart in a number of places by rough processes, some of which 
were finger-shaped and two to two and one-half inches in 
length. Other of these processes were shred-like.
