126 ANEURISM IN THE BENDING OF THE ARM IN A COW. 
which I had made. I immediately detected a soft, yielding sub- 
stance, which 1 could readily break down with my finger, and suc- 
ceeded in bringing out a piece of pure coagulated blood. This was 
followed by another gush of blood, which threatened to continue 
to flow. I passed a suture through the lips of the orifice, and 
ordered the cow to be kept in. I also inserted a seton in front of 
the enlargement. 
The incision which I had made readily healed, and although the 
tumour did not diminish in size, I hoped that in time it might do 
so, for no pulsation could be felt in it, or had been in any of its 
stages. I recollected, also, the opinion of Sir Astley Cooper, that 
“ the force of the pulsation is in the inveise proportion of the size 
of the aneurism,” and this, if it was an aneurism, was a very large 
one. Considering it to be a spurious or false aneurism, I inferred 
that already some of the blood in the cyst — that most distant from' 1 
the current — had become coagulated, and I trusted that the depo- 
sition of coagula would go on until the cyst had become filled — 
then, the blood no longer circulating through the cyst, either the 
vessel which supplied it would become obliterated, or a false mem- 
brane being thrown across its ruptured parietes, nature would next 
proceed to remove the deposit by absorption, or cast it off from the 
system by suppuration and ulceration. After the lapse of a few 
days, slight haemorrhage from the part came on, which continued 
at intervals for seven or eight days, when it ceased. The tumour 
was now lessened in size ; but after this it continued for a week or 
more in an apparently indolent state. I therefore ordered a sti- 
mulant to be rubbed in daily, consisting of the liniment of can- 
tharides and oil of turpentine, which appeared to increase the 
action of the absorbents, for, after the lapse of a fortnight, very 
little of the original enlargement remained, and that continued 
stationary. 
Your opinion on this case, in the pages of your inestimable Jour- 
nal, The VETERINARIAN, would be thankfully perused, and parti- 
cularly as to the vessel which was actually involved. 
[I perfectly understand the meaning of my friend, Mr. Snewing, 
that, while the anatomy of the ox has not, until Mr. Spooner 
nobly commenced the task, been taught at the English Ve- 
terinary College, the author of the work on “ Cattle ” has very 
superficially treated this subject, and has been quite silent as to 
the arterial circulation in the upper portions of the extremities of 
cattle. He pleads guilty to the charge. It was the natural 
consequence of the brief and superficial description of the greater 
portion of the anatomical structure of these animals, to which 
the limits and the plan of that work confined him.
