every four or five hours) may be
given for a short time, but should be discontinued as soon as the fever
begins to abate. Aconite is a valuable drug in the hands of the intelligent
practitioner, but my experience leads me to believe that not infrequently
animals are lost by its injudicious use, for in many febrile conditions it
is positively contraindicated, owing to its action upon the heart. In a
plethoric animal, with a strong, bounding pulse, bleeding may be resorted
to instead of administering aconite. If the bowels are constipated,
calomel, 1 to 3 drams, which acts as a cathartic and a febrifuge, is
advisable. In the second stage diffusible stimulants are required, viz:
Spirits of nitrous ether, 2 ounces; aromatic spirits of ammonia, 1 ounce;
mix, and give in gruel three times daily. In some cases carbonate of
ammonia, 2 to 5 drams, has been found beneficial. Most practitioners apply
counterirritants, such as mustard plasters, turpentine, and ammonia
liniment, or cantharides.

EMPHYSEMA (HEAVES).

Emphysema is a rupture of the minute air vesicles of the lung substance,
and may be either interlobular or vesicular. There is an extreme
interference with respiration, inspiration being short and expiration
prolonged. It is a nonfebrile condition, in which the appetite is not
decreased and the milk secretion is kept up. It may be caused by an attack
of asthma or may result from chronic bronchitis. The disease can be
diagnosed by the marked interference with respiration. The animal, as a
rule, is emaciated, has a staring coat, and is hidebound. If percussion is
resorted to, the animal's chest will give a tympanic, drumlike sound. The
normal resonant sound is exaggerated.

_Treatment._--The disease is incurable, and only a palliative form of
treatment can be carried out. The destruction of the animal is often
advisable, from a humane as well as from a financial point of view.

PULMONARY CONGESTION.

Cattle that are overdriven or overworked are liable to pulmonary congestion
in an acute form, and sometimes to pulmonary apoplexy. In such cases they
should be allowed to rest, and if the weather is hot, they should be put in
a shady place. Give stimulants internally, unload the venous side of the
heart by bleeding, and apply stimulating applications to the legs, and
bandage.

HEMOPTYSIS.

Hemoptysis is a term used to signify bleeding from the lungs. The trouble
may result from a previous congestion of the lungs
