indicated. A cantharides blister may be applied, or the following ointment
used: Biniodid of mercury 1 part, lard 6 parts; mix. In some cases it will
be found necessary to repeat the application.

BRONCHITIS.

Bronchitis is an inflammation of the mucous membrane of the bronchial
tubes. When a primary disease, it is generally the result of what is
commonly known as "catching cold." It may be secondary to or complicated
with many of the diseases of the respiratory system. It may also be caused
by breathing irritating gases, or by the introduction of foreign bodies
into the bronchial tubes, which sometimes results from injudicious and
careless drenching when the larynx is temporarily relaxed. It may be acute
or chronic, and is divided, according to the seat of the inflammation, into
bronchitis proper when the large tubes are affected, or capillary
bronchitis when the trouble is in the smaller ones.

_Symptoms._--Loss of appetite, elevation of temperature, generally 104 deg. or
105 deg. F. The inspiration is incomplete, short, and painful, and the
expiration is prolonged. The pulse is increased in frequency and is hard. A
characteristic, painful cough is present, but it is paroxysmal and
incomplete. Auscultation and percussion greatly aid us in a diagnosis. A
normal sound is given on percussion. On auscultation, in the early stages,
rhonchus rales are detected if the larger tubes are affected, and sibilant
rales if the smaller ones are affected. Later mucous rales are noted, and
sometimes all sounds in certain parts are absent, owing to the plugging up
of the tubes. This plugging, if extensive enough, is sometimes the cause of
death, or death may result from extension of the disease to the lungs or
pleura.

_Treatment._--The animal should be placed in a light, well-ventilated box,
and the bowels kept in a soft condition by enemas, etc. Violent purgatives
should not be used. The body should be kept warm by blanketing. In the
early stages a draft composed as follows should be given three times daily:
Extract of belladonna, 2 drams; solution of acetate of ammonium, 4 fluid
ounces; water, one-half pint. In the later stage of the disease the
following formula may be substituted and given twice daily: Carbonate of
ammonium, 3 drams; liquor hydrochlorate of strychnin, 2 fluid drams;
spirits of nitrous ether, 1 fluid ounce; water, one-half pint.

In some cases the following is preferable to either of the abov
