ular causes. When the larynx is the seat of the
affection, the cough, should it once begin, continues for a considerable
time; and cold air or excitement will invariably induce it. In bad cases
every act of inspiration is followed by a kind of noise intermediate
between a grunt and a cough. Sometimes the breathing is accompanied by a
species of roaring; and I have seen one case in which a blood-hound had
every symptom of laryngismus stridulus, or the crowing disease of the
human infant.

Laryngeal disorders are seldom brought under our notice until they are
confirmed, and they are difficult to cure in proportion to the length of
time they have existed. The food in every case must be rigidly regulated,
and no solid flesh should be allowed; but if the animal be very old or
weak, beef tea or gravy may be added to the rice or biscuit which
constitutes the chief portion of the diet. The condition of the stomach
must so far as possible be ascertained, and the medicines necessary to
correct its disease should be administered. The exercise must not be
stinted, neither should confinement within doors be insisted upon. All
must be done to assist the digestion and invigorate the health; such
precautions being adopted as prevent the aggravation of the disease.
Sudden changes of atmosphere, as from a warm room to a frosty air during
the depth of winter, should obviously be avoided; neither would it be
prudent to race the animal about, or induce it to perform any action
calculated to accelerate the breathing.

At the commencement a gentle emetic given every other morning until six or
seven have been administered, with a laxative occasionally if the bowels
are torpid, is often productive of speedy benefit. A mustard poultice to
the throat is also to be recommended, but he who applies it must be
attentive to remove it when it appears to seriously pain the animal. It
may be repeated on each successive night, or even oftener, but should
never be reapplied before the skin on which it was previously placed has
ceased to be tender. Leeches to the throat are often of service, as also
are small blisters to the chest. I found great improvement result from
wearing a very wide bandage, which was kept wet, and covered with oil
silk, round the neck. This is easily made, and strips of gutta percha, or
stout leather, will prevent it being doubled up by the motions of the
head; and it is scarcely a disfigurement, since it only looks like a large
