arsenicum when there exist a wheezing cough and sound when breathing; 
short, hurried, difficult breathing when going up a hill. Give nux vomica 
when the symptoms are aggravated, especially those showing indigestion, 
such as passage of hay and oats, windy stomach and intestines, and thin, 
seedy appearance of the animal. One of the best remedies for this disorder, 
and one which rarely fails to give relief, is lobelia. It should be given in 
doses of a half-teaspoonful to a teaspoonful of the tincture two or three 
times a day. The following formula will also be found useful: 
Tincture of lobelia, 4 ounces. 
Fowler’s Solution, 1% ounce. 
Iodide of potassa, I ounce. 
Water, 4 ounces. 
Mix. 
Give a teaspoonful three times a day. Give the best an:1 most nourish- 
ing food frequently, but in small quantities, avocding chaff and dusty hay. 
Do not give more than five pounds of hay in a day, but increase the allow-

tion in their use. Impose slow work or three or four hours daily of walk- 
ing, but give no exercise soon after eating a meal.

frequently found in low-bred horses with badly-shaped chests, which eat 
ravenously. It is a thickening of the membranes lining the bronchial tubes, 
so that the horse, when violently worked after feeding, or when the stomach 
is full, has defective breathing, with blowing but not notse. 
Symptoms.—Short, quick, difficult breathing during any exertion, 
especially while ascending a hill. 
TREATMENT.—This is incurable, but is relieved by the use of arseni- 
cum, nux vomica, ammonium causticum and bryonia, and by the gerieral 
care to be observed in Broken Wind (previous section). 
WHISTLING.—ROARING.—BLOWING. 
An obstruction of the air-passages produces sounds of differing char- 
acter, and from these the horse is called a whistler, roarcr, blower, grunter, 
and the like. These difficulties are often taken from the sire or dam, and 
are promoted by laryngitis, bronchitis, and other respiratory diseases; also 
by the inflammation which often results from tight reins, and from always 
driving a horse on the same side, by which the muscles of the larynx on the
