110 DISEASES OF THE HORSE, 
pleurodynia, or rheumatism, and other affections accompanied with 
much pain, will grunt when moved, or when the pain is aggravated, 
but grunting under these circumstances does not justify the term of 
“ orunter” being applied to the horse, as the grunting ceases when 
the animal recovers from the disease that causes the pain. 
High blowing. —This term is applied to a noisy breathing made by 
some horses. It is distinctly a nasal sound, and must not be con- 
founded with “roaring.” The sound is produced by the action of the 
nostrils. It is a habit and not an unsoundness. Contrary to roaring, 
when the animal is put to severe exertion the sound ceases. An ani- 
mal that emits this sound is called a “high blower.” Some horses 
have naturally very narrow nasal openings, and they may emit 
sounds louder than usual in their breathing when exercised. 
Whistling is only one of the variations of the sound emitted by a 
horse called a “roarer,” and therefore needs no further notice, except 
to remind the reader that a whistling sound may be produced during 
an attack of severe sore throat or inflammation of the larynx, which , 
passes away with the disease that causes it. 
CHRONIC BRONCHITIS. 
This may be due to the same causes as acute bronchitis or it may 
follow the latter disease. An attack of the chronic form is liable to 
be converted into acute bronchitis. by a very slight cause. This 
chronic affection in most instances is associated with thickening of 
the walls of the tubes. Its course is slower, it is less severe, and is not 
accompanied with so much fever as the acute form. If the animal is 
exerted, the breathing becomes quickened and he soon shows signs of, 
exhaustion. In many instances the animal keeps up strength and 
appearances moderately well, but in other cases the appetite is lost, 
flesh gradually disappears, and he becomes emaciated and debilitated. 
It is accompanied with a persistent cough, which in some cases is 
husky, smothered, or muffled, while in others it is hard and clear. A 
whitish matter, which may, be curdled, is discharged from the nose. 
‘If the ear is placed against the chest behind the shoulder blade, the 
rattle of the air passing through the mucus can be heard within. 
Treatment.—Rest is necessary, as even under the most favorable 
circumstances a cure is difficult to effect. The animal can not stand 
exertion and should not be compelled to undergo it. It should have 
much the same general care and’ medical treatment. prescribed for 
the acute form. Arsenious acid in tonic doses (3 to 7 grains) three 
times daily may be given. As arsenic is irritant, it must be mixed 
with a considerable bulk of moist feed and never given alone. Ar- 
senic may be given in the form of Fowler’s solution, 1 ounce three 
times daily in the drinking water. An application of mustard ap-
