252 ON THE PRESENT EPIZOOTIC AMONG HORSES. 
rians of limited observation seizing on them as essential charac- 
teristics of’ the disease. Bronchitis is certainly the most frequent. 
The practitioner ought, however, to make his diagnosis with ex- 
treme care, and not let the merely accelerated respiration deter- 
mine in his mind the necessity of abstracting blood. There are 
frequently cases where, although the state of the respiration may 
be alarming, the pulse is not sufficiently deranged to indicate 
bleeding. No rule, however, can be laid down that will not admit 
of many exceptions. Where complications occur requiring the 
abstraction of blood, the symptoms almost invariably indicate its 
necessity. Those organs and tissues accidentally implicated 
will of course require the peculiar treatment necessary for each 
when suffering under idiopathic derangement, excepting that 
some modification will generally be found necessary, according 
to existing circumstances. It would be as absurd to say, “ Do 
not bleed under any circumstances,” as it would be to advise it 
in every case indiscriminately. It must not, however, be for- 
gotten that the disease under consideration, which repeated and 
comparative experiment has proved, will not alone recover with- 
out the use of the lancet, but also will recover in a much shorter 
space of time than when blood has been abstracted. I have al- 
ready had three hundred and seventy-three cases of this affection, 
all of which recovered. In the majority of instances the dura- 
tion of the disease is from four to seven days. Many will recover 
without the assistance of any medical aid, requiring but to be 
placed in an airy situation, and have their diet duly restricted. 
Consequences and secondary Symptoms. — Frequently, after the 
acute attack is past, there remain derangements of function which 
shortly assume a decidedly chronic character; such as nasal flux, 
with tumefaction and soreness of the submaxillary lymphatic 
glands ; an ophthalmic affection, where there is inflammation, 
opacity, and sometimes even ulceration of the transparent cor- 
nea, with effusion of lymph or blood into the anterior chambers 
of the eye, the latter being but very tardily acted on by the ab- 
sorbents ; oedema of the legs; chronic bronchitis, &c. Some- 
times the animal is in a state of apparent convalescence, when 
suddenly one or more of the legs become affected with a. species 
of erysipelatous inflammation, giving such intense pain, that the 
affected limb cannot be put to the ground for the purpose of as- 
sisting even in the support of the body, much less in progression. 
These, and many other affections, too numerous for detail, are 
frequently found to evince themselves after the original disease 
has run its course. The animal being now, generally speaking, 
comparatively recovered of the primary disorder, they may, with 
few exceptions, be treated in the ordinary manner. In such
