THE HORSE—THE RESPIRATORY ORGANS. 115 
tinct; the horse is restless, paws, rises and lies down frequently, wanders un- 
consciously around the stall, becomes worn out, falls and dies. 
The symptoms of this disease which distinguish it from others with 
similar indications, especially plezrodynia, are these:—The sound as of the 
palms of the hands rubbed together, heard upon placing the ear to the sides 
of the chest; the variation in pulse and breathing; the animal appearing 
alternately better or worse at uncertain hours; the attempt to check the 
painful cough; the pain and grunt incident to pressure or striking on the 
diseased part (pain being caused by manipulation, w7thout pressure, in 
pleurodynia); the short, catching breath, and the difference in time between 
taking in and expelling the breath. 
TREATMENT.—Aconite and bryonia are the best remedies for the 
primary or inflammatory stage, and should be given alternately every hour 
until a perceptible change occurs in the pulse and respiration, and then at 
intervals of three or four hours. After the inflammatory symptoms have 
disappeared give a few drops of arsenic or digitalis to promote the action 
of the kidneys and prevent effusion. Observe the same general care as to 
stabling, diet and other particulars as was laid down for Pneumonia. 
If there be evidences of water in the chest, consult the remarks on 
Hydrothorax. 
BROKEN WIND.—HEAVES, 
This disorder is most common in low-bred and cart horses, and is a 
difficulty in breathing, marked by a double expulsion of the breath, with 
fits like those of asthma. It originates in disorder of the nerves of the 
lungs and stomach, or rupture of some air-cells, and is excited by irregular 
work, improper feeding, such as clover-hay, or any dusty hay. It may 
follow chronic cough, or inflammation of the lungs and bronchial tubes. 
Symptoms.—Short, suppressed, and very feeble cough, often attended 
with expulsion of wind from the anus; breathing consists of one effort at 
drawing in air and two at expelling it; indigestion, with oats and hay in the 
dung; when the animal draws a heavy load or trots rapidly, the flanks 
heave violently, with a wheeze in the breathing in many cases, xot alt, 
which does not cease at once when the animal is brought to rest; when the 
horse is in the stable, if the ear is applied to the chest, especially at night, 
a wheeze and rattle are heard, which are sometimes sonorous; suppressed 
natural murmur of breathing, with increased resounding from a stroke, 
and difficulty of breathing. 
TREATMENT.—Broken wind, in early stages, is curable; after it has 
run a considerable time without treatment, it can only be relieved. Give
