That all arteries may become the seat of disease and may be 
found plugged up by clots, no one will deny, and that according 
to the location of the diseased process a different series of symp¬ 
toms will be observed. Bollinger has shown us how it may often 
be the cause of fatal attacks of colic. Bouley and Goubaux have 
taught us how it may be accompanied by entire paraplegia or by 
peculiar forms of lameness of otic or both of the hind extrem¬ 
ities. 
It is with the desire of increasing the number of recorded ob¬ 
servations in our English literature that we present our readeis 
the two following cases : 
Thanks to the kindness of Mr. Lockhart, M.R.C.V.S., and 
Prof. Robertson, M.D., Y.S., of New York, we had the opportunity 
to observe them and to make post-mortem examinations, and in 
both the symptomatology and lesions, we hope, will be found as 
they were to us, most interesting and instructive. In the first 
one we made no positive diagnosis, as the animal died before we 
ebuld proceed to our examination. In the second, on the contrary, 
we had the satisfaction not only to confirm it, but also that of the 
students of the American Veterinary College, before whom we had 
the pleasure of developing the symptoms almost to our will. But 
what will prove most interesting to the old practitioners, and what 
will probably be difficult to understand, is the excessive and sud¬ 
den development of the symptoms, their rapid and fatal termina¬ 
tion, while at the same time, by the condition of the lesions, 
there will not remain the slightest doubt, for one horse at least, 
that the diseased process must have existed for several months 
before anything amiss could be detected. 
The first case is that of a handsome bay horse, about seven 
years old, who, up to some months ago, had never been sick. 
At that time he became lame forward, and after treatment was 
sent out to the country. Being needed for work, lie was brought 
back to the city. On arriving at the owner’s stable he was found 
in perfect condition and perfectly able to resume his work, with 
the exception of a little swelling on his sheath which was oedema- 
tous, slightly warm and not painful. He then received a dose of 
cathartic, and with some hygienic care in cleansing and diet he was
