ough might be noticed, and
that the appetite and milk-secretion diminished. The animal becomes
costive, and the shivering fits recur. The cough becomes more constant
and oppressive; the pulse full and frequent, usually numbering about
eighty per minute at first, and rising to upwards of one hundred. The
temperature of the body rises, and all the symptoms of acute fever set
in. A moan, or grunt, in the early part of the disease indicates a
dangerous attack, and the _alae nasi_ (cartilages of the nose) rise
spasmodically at each inspiration; the air rushes through the inflamed
windpipe and bronchial tubes, so as to produce a loud, coarse
respiratory murmur; and the spasmodic action of the abdominal muscles
indicates the difficulty the animal also experiences in the act of
expiration. Pressure over the intercostal (between the ribs) spaces, and
pressing on the spine, induce the pain so characteristic of pleurisy,
and a deep moan not infrequently follows such an experiment. The eyes
are bloodshot, mouth clammy, skin dry and tightly bound to the
subcutaneous textures, and the urine is scanty and high-colored.

Upon auscultation, the characteristic dry, sonorous _rale_ of ordinary
bronchitis may be detected along the windpipe, and in the bronchial
tubes. A loud sound of this description is, not infrequently, detected
at the anterior part of either side of the chest; whilst the respiratory
murmur is entirely lost, posteriorly, from consolidation of the lungs. A
decided leathery, frictional sound is detected over a considerable
portion of the thoracic surface. As the disease advances, and gangrene,
with the production of cavities in the lungs, ensues, loud, cavernous
_rales_ are heard, which are more or less circumscribed, occasionally
attended by a decided metallic noise. When one lobe of the lungs is
alone affected, the morbid sounds are confined to one side, and on the
healthy side the respiratory murmur is uniformly louder all over.

By carefully auscultating diseased cows from day to day, interesting
changes can be discovered during the animal's lifetime. Frequently, the
abnormal sounds indicate progressive destruction; but, at other times,
portions of the lungs that have been totally impervious to air, become
the seat of sibilant _rales_, and gradually, a healthy respiratory
murmur proves that, by absorption of the materials which have been
plugging the tissues of the lungs, resolution is fast advancing. Some
very remark
