tion of the bowels
occurred for three days, and the pains of laminitis were added to by the
usual pains of intestinal obstruction.

The colic of enteritis is in some cases caused by the nature of the food,
giving rise to laminitis. In our opinion, however, it is more often
occasioned by the drastic action of the aloes nearly always resorted to in
the treatment of the disorder. As does the pneumonia, the enteritis thus
brought about nearly always has a fatal termination.

_(c) Gangrene of the Structures within the Hoof_.--This complication is
the one most to be dreaded. It occurs as a result of the great pressure
exerted by an excessive exudation, and doubtless affects first the laminae
and softer structures. Once commenced, however, it rapidly extends to death
of the other structures (ligament, tendon, and even bone), and gives a
fatal ending to the case.

That gangrene of the tissues ("mortification" as our older writers called
it) has occurred is soon made evident to the veterinarian by the symptoms
shown by the patient. The agonizingly acute pains suddenly subside, the
feet are placed firmly and squarely to the ground, and the animal walks
with ease. Perhaps but the night before the patient is seen racked with
excruciating pain; the morning sees the astounding change of apparent
absolute recovery. Too well, however, the eye of the experienced veterinary
surgeon sees that such is not the case. Even before proceeding to take a
record of the other symptoms, he knows that it is but the commencement of
the end. Methodically, however, he notes the other conditions. The pulse
he finds small and imperceptible, save at the radial. The thermometer
registers a subnormal temperature, the extremities are cold, and cold
sweats bedew the body. To the same experienced eye the countenance of the
animal is almost suggestive of what has occurred. The drawn and haggard
expression, to which we have previously referred, becomes more marked, and
the angles of the lips are drawn back in what has been described by some
writers as a 'sardonic' grin.

We can best express what the whole look of the animal's countenance
indicates to us by saying that it gives us the impression that the animal
himself knows that some serious change, and a change fatally inimical to
his chances of life, has taken place in his feet.

It may be that in some odd cases, although it has not yet been our lot to
meet with them, gangrene may terminate in the casting o
