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 remarkable cases of this description have been encountered in practice. Unfortunately, we often find a rapid destruction of the tissues of the lungs, and speedy dissolution. In other instances, the general symptoms of hectic,
or consumption, attend lingering cases, in which the temperature of the body becomes low, and the animal has a dainty
appetite, or refuses all nourishment. It has a discharge from the eyes, and a fetid, sanious discharg
