2 DISEASE OF THE HEART IN' THE COW AND HORSE. 
organ by itself minutely. I found every viscus in the abdomen 
quite sound. The intestinal canal throughout contained a 
quantity of the same tar-like excrement before noticed. The 
chest was next laid open, when I was surprised to find the 
lungs in a perfectly normal condition. The heart, viewing it 
externally, appeared also healthy. On making dn incision a 
little to the right of*the septum ventriculorum, however, be¬ 
ginning at the auriculo-ventricular opening and carrying it 
round, the nature of the case was at once evident. Growing 
from the septum was a large tumour, the size of a common 
breakfast cup. Attached also to the tricuspid valves and 
chordse tendinse were numerous other growths of a similar 
nature, varying in size from a large pin’s-head to a horse-bean. 
They were all distinctly fibrous in their nature, and could be 
torn into shreds, the same as a piece of macerated tendon. In 
the centre of the large growth the process of suppuration had 
commenced. The other cavities of the heart contained no trace 
of any abnormal products. 
Case II.—On the 26th August my attention was directed 
to a black filly of the cart kind, two years old, (the property of 
Mrs. Baker, of Litton) on account of lameness in the off hind 
leg. She was out at grass, and, with the exception of trifling 
lameness, appeared all right. There was some little fulness 
about the anterior part of the hock, which was hotter than 
natural; so I merely prescribed a little lead lotion, not thinking 
it requisite to take her up. I heard no more of her until the 
16th of September, when I was again requested to see her, as 
I was told she was still lame, looked thin, and doing badly. I 
had her brought up, when I found her in a strange emaciated 
condition. Her pulse was between 60 and 70, and very weak. 
Visible mucous membranes blanched, and she was sadly lame. 
The sheath of the flexor tendons was now evidently the site of 
lameness, they being swollen and tender to the touch. I con¬ 
sidered it to be a case of rheumatism, so had her placed in a 
warm box, and gave a mild purge, and ordered a poultice to 
the lame leg. 
19th .—No alteration. The medicine has acted upon her 
bowels. She does not eat much; lies a good deal; but is never 
heard to cough. Left a little fever medicine, and ordered the 
poultice to be continued. 
22 d. — She was a good deal better of her lameness, but 
breathed with difficulty, and ate very little. She was evidently 
growing weaker. I left some tonic balls to be given night 
and morning, and ordered her some boiled oats, malt mash, or 
any thing she would eat. 
27/A.—Found my patient much the same in every respect.
