The symptoms of the disease are
drooping of the ears and disinclination for food. The animal soon
succumbs, and when the carcase is opened the lungs are found to be
rotten.

Horses out at pasture are free from all diseases excepting disease
of the feet. From this disease they sometimes lose their hooves: but
after losing them they grow them soon again, for as one hoof is
decaying it is being replaced by another. Symptoms of the malady are a
sinking in and wrinkling of the lip in the middle under the
nostrils, and in the case of the male, a twitching of the right
testicle.
Stall-reared horses are subject to very numerous forms of disease.
They are liable to disease called 'eileus'. Under this disease the
animal trails its hind-legs under its belly so far forward as almost
to fall back on its haunches; if it goes without food for several days
and turns rabid, it may be of service to draw blood, or to castrate
the male. The animal is subject also to tetanus: the veins get
rigid, as also the head and neck, and the animal walks with its legs
stretched out straight. The horse suffers also from abscesses. Another
painful illness afflicts them called the 'barley-surfeit'.
