s are quick and shallow;
the nostrils are dilated; the pulse is full and hard. Cough may or may not
appear in this stage. The nose is hot and dry; the tongue sometimes
protrudes and is slimy; the coat is staring, and the skin dry and harsh.
The urine is usually diminished in quantity, high colored, and the bowels
constipated. The animal stands with the forelegs wide apart to facilitate
respiration. On auscultation crepitation will be observed over the portion
of the lung affected. The sounds elicited on percussion are practically
normal in this stage.

In the second stage the temperature generally drops one or two degrees, and
respiration is performed with much difficulty. The cough is frequent and
painful. The animal still stands with the forelegs wide apart and the
elbows turned outward. If it assumes the recumbent position it rests on the
sternum. All secretions are more or less suspended, particularly the milk
in cows. The animal has a haggard appearance, and the pulse becomes small
and wiry at this period. The extremities are hot and cold alternately; the
crepitation which was present in the first stage is now absent, and no
sound on auscultation is heard, unless it is a slight wheezing or whistling
noise. On percussion dullness over the diseased lung is manifested,
indicating consolidation. The lung has now assumed a characteristic
liverlike appearance.

In the third stage, if the disease is to terminate favorably, the cough
becomes loose, the animal improves, the appetite returns, and the symptoms
above detailed rapidly subside; if, on the other hand, resolution is not
progressing, the lung substance degenerates, becomes clogged up, and ceases
to function. In fatal cases the breath has a peculiar, fetid, cadaverous
odor, and is taken in short gasps; the horns, ears, and extremities become
cold and clammy, and the pulse is imperceptible. On auscultation, when
suppuration is taking place and the lung structure is breaking down, a
bubbling or gurgling crepitation, caused by the passage of air through pus,
is heard.

_Treatment._--Good hygienic surroundings and good nursing are essential in
connection with the medical treatment. The probability of recovery depends
largely on the extent of the lung tissue involved, as well as on the
intensity of the inflammatory process. In the early stage, when the fever
is high, febrifuges should be given. If the pulse be strong and full,
aconite (Fleming's tincture, 1 to 2 drams,
