resistance when taken by surprise, and the physical agents which 
surround it so suddenly modified ; the animal also, in spring and 
autumn, from moulting, is more sensitive to these changes. At 
these particular seasons we always get more catarrhal affections, 
especially if such seasons are ungenial. I would place also ple- 
thora and its opposite extreme, poverty, among the predisposing 
causes. 
The result or termination of strangles is often complicated and 
uncertain ; for, although if we have had good abscesses form and well 
ripen, the animal may do well, and by his after-thriving appear as 
though nature had rid his constitution of some impurity, this is not 
always the case. Secondary abscesses will sometimes form in all parts 
of the body, and more markedly so in irregular strangles, at some 
special season, and in some particular localities. How frequently 
do we find from some cause hidden from the ken of man, that at 
times wounds of most trivial kind assume unhealthy action, and 
this to such extent that the veterinary surgeon dreads to perform 
the most simple operation. It is so also with the disease in question. 
One month or year we get every case to do well, another nearly all 
do badly, causing us no end of trouble, and the most untoward 
results follow. Then it behoves us to be watchful, and I would 
caution the young practitioner, especially in such seasons, to be 
careful. Perhaps to better illustrate my meaning I may be allowed 
to quote a case bearing somewhat on this point. A nobleman pur- 
chased of an eminent dealer a pair of valuable young carriage horses, 
which I was requested to examine. The one horse I rejected in 
consequence of sore throat and other evidence of strangle fever ; but 
as the dealer consented to treatment being adopted, and was willing 
to abide the result, the horse was kept. Good abscesses formed, 
and the disease having run its course the horse was cantered, 
anxious to learn if any symptoms of roaring were left. He made a 
slight noise, but it was of such nature that I felt convinced it would 
not be permanent. Just one of those cases that nature will cure, 
only give her time. The owner, however, not liking the delay, 
a seton was inserted under throat. In about a week a small 
abscess formed on its course and broke. A few days later the horse 
was off feed, and an immense abscess began to show itself on the 
shoulder. Fearing I had a case of pyaemia, I immediately removed 
the seton, when, for nearly three months, abscesses kept forming 
all over the body, and the horse showed great feverish excitement. 
With care, liberal diet, and plenty of tonics, he got well, and has 
worked sound to this day, notwithstanding which I opine it was a 
genuine case of pyaemia, the seton being the exciting cause. 
Chronic disease of mesenteric glands, leading to great emaciation, 
is often a result of strangles, also confirmed roaring. Professor 
Gamgee, in ‘ Veterinary Review,’ relates a case of arteritis following 
it, also in ‘ Our Domesticated Animals’ speaks of frequently finding 
the guttural pouches plugged with consolidated pus as a sequel. I 
never met with but one case of this kind, and as I did not get the 
early history of my patient, could not trace its true origin ; but the
