appears to the feel hard, more
or less cordy, and pulseless, or giving a sensation of fluttering, as of
a small volume of blood with a trickling motion passing through a
confined space, the difference between the sides will make the case
plain. The first will be the full flow of the circulation through an
unobstructed channel, the other a forced passage of the fluid between
the thrombus and the coats of the artery. In such case the prognosis is
necessarily a grave one and the disease is more liable to grow Worse
than better.

_Treatment._--No form of treatment can be advised; the suffering or a
helpless and useless animal can only be terminated by that which ends
all.

Cases occur, however, where this condition of the blood vessels exists
in a much less degree, and the diseased condition is not sufficiently
pronounced for final condemnation. There may even be a possibility of
the absorption of the clot, or that an increase of the collateral
circulation may be sufficient to supply the parts with blood. In such
cases spontaneous recovery may follow moderate exercise in the pasture,
field, or stable, or continuous light work may be given, but too much
hope should not be placed in such treatment.

SPRAINS OF THE LOINS.

This is an affection which suggests to the mind the idea of muscular
injury, and is difficult to distinguish from many similar cases. If the
animal shrinks from the slightest pressure or pinching of the spine in
the region of the loins, he is by many pronounced to be "lame in the
loins," or "sprained in the loins," or "weak in the kidneys." This is a
grave error, as in fact this simple and gentle yielding to such a
pressure is not a pathological sign, but is normal and significant of
health. Yet there are several conditions to which the definition of
"sprains of the loins" may apply which are not strictly normal.

_Cause._--The muscles of the back and those of the loins proper, as the
psoas, may have been injured, or again there may be trouble of a
rheumatic nature, perhaps suggestive of lumbago. Diseases of the bones
of the vertebral column, or even those of the organs of circulation, may
give rise to an exhibition of similar symptoms.

_Symptoms._--The symptoms are characteristic of a loss of rigidity or
firmness of the vertebral column, both when the animal is at rest and in
action. In the former condition, or when at rest, there is an arched
condition of the back and a constrained posture in st
