22 TUMOURS IN THE THORACIC CAVITY OF A COW. 
I found her looking very thin ; coat staring, and the jugular 
veins distended apparently almost to bursting ; the pulse 
was indistinct at the jaw, nothing more than a waving being 
felt ; the action of the heart laborious, and the symptoms gene- 
rally were very unfavorable. This being altogether a novel 
case to me I was almost at a loss to know what to do. I, 
however, bled her largely, which there was no difficulty in 
doing without a cord, but I was much perplexed in pinning 
up the orifice, in consequence of the distension of the vessel; 
the cause of which was then to me unknown. After the 
bleeding she was somewhat relieved ; I then gave her aperient 
and febrifuge medicines, and left her for the day. On the 
next day I visited her again and found the laxative ope- 
rating freely, and altogether I thought her a little better. 
Repeated the fever medicine. She seemed to improve for two 
or three days, after which she experienced a relapse. I bled 
her again, and repeated the medicines, but without any bene- 
ficial effect. She continued to get worse in fact, and I there- 
fore told the owner that I could do her no good, and advised 
him to have her destroyed. To this he did not consent, but 
said, he would let her die, as she was worth nothing if killed. I 
asked him if he would let me know when she died that I 
might examine her? and this he did in the course of a few 
days. Being from home at the time, 1 did not arrive before 
they had partly cut her up, but I saw enough to convince 
me of the cause of her illness and death. The heart was 
surrounded by a mass of calcareous matter, contained in cells 
of various sizes, resembling a bunch of grapes, which was 
adherent to the parietes of the chest, completely filling that 
cavity, and compressing the heart so that its free motion 
was impossible. The lungs were only slightly diseased. I 
did not weigh the mass, but I suppose it weighed at least 
two or three stone. 
In the summer of the same year I attended another case 
of the same kind, presenting similar symptoms, but the 
animal was more emaciated. I at once advised the owner to 
have it destroyed, which was accordingly done, and the 
appearances after death were precisely the same as those 
above recorded. These are the only two cases of the sort I 
have ever seen. 
I am, dear sir, yours truly. 
[The existence of osseous tumours within the thoracic 
cavity of the genus bovis, is by no means uncommon, as 
from the archives of veterinary science many cases might be 
brought forward similar to those here recorded. Nevertheless
