e animal that made
it changes its position. The next time it may rise, look round, and seek
another place; which having found, it appears to settle itself and to go
to sleep. The rest once more is broken, the voice grows more full and
loud; the dog jumps up and runs about for a little while, then selects a
spot where it curls its body tightly up, as if resolved to have out its
nap. The interruption, however, constantly recurs; and at each return the
exclamation is more emphatic--the starting more energetic--the movement
more abrupt--and, contrasting these, the determination or desire to repose
becomes more strong. Thus endeavoring to sleep, and being constantly
disturbed by some sharp and shooting pain, the dog may continue for a day,
or two, or three, its cries, during the whole period, offending a
neighborhood.

During the continuance of colic, the general appearance of the animal may
be but little affected. The eye is not injected, but the pupil may be
slightly enlarged. The nose is cool and moist, but towards the end,
irritation may render the part hot or dry. The appetite is generally
slight--sometimes lost; and fluids are more readily accepted than solids.
The cry, however, should be remarked; because, with the pulse, it gives
the earliest notice when inflammation is commencing. While colic alone
exists, the pulse may, from pain, be accelerated, and rendered more full,
as well as strong, though not always to any marked extent. In
inflammation, the pulse is greatly quickened, the artery becomes smaller,
and its beat more jerking or wiry. During simple spasm the voice is
natural, rich, sonorous, and almost musical; but in inflammation it is
short, harsh, high, and broken, the exclamations not being continuous, but
consisting of a series of disconnected "_yaps_."

For the treatment, in the first instance, a turpentine enema will
frequently cut short the attack. Should it fail to so, injections of ether
and laudanum should succeed, and doses of the mixture should also be given
every half hour; the first three being exhibited at intervals only of a
quarter of an hour each. The cathartic pills should be administered; and
in three hours, if the bowels have not been acted upon, a dose of
castor-oil should be resorted to; but where the cathartic has been
responded to, the castor-oil should be delayed for eight or twelve hours.

When the pain ceases, the ether and laudanum should not be immediately
discontinued; but they
