horse is made to jump quickly by a cut from a whip, or 
after walking a short distance. 
These forms ot chorea are most severe in cold weather 
aud usually gradually increase in severity as the ani- 
mal grows elder. In dogs, chorea is usually seen as an 
irregular jerking of the muscles of the head or some 
other part, or even the entire body. In horses, there 
is sometimes a jerking of sets of muscles, unless the 
disease is severe. Chorea does not seem to cause suffer- 
ing, nor to interfere seriously with the general health 
of the animal. 
In most cases of chorea, medicinal treatment does 
not give great benefit, unless it is the result of other 
disease. Good results often follow careful feeding and 
tonics. The food should be nutritious, easily digested, 
of good variety, and abundant. For horses, a mix- 
ture of oats, oil-meal and bran is good. Give the 
horse three tines a week the following: Common salt, 
four ounces; sulfur, two ounces; hard-wood ashes, 
two ounces;—a tablespoonful of the mixture in the feed. 
Also, give Fowler’s solution (of arsenic), beginning 
with half-ounce doses in the feed, once daily, and 
gradually increasing by one-fourth ounce at a time 
until one ounce is given at a dose in the morning 
and the same at night. The arsenie should be given 
for two weeks and then withheld for two weeks and 
repeated. Dogs may be given Fowler’s solution, begin- 
ning with one-drop doses once daily and increased 
one drop a day until five to ten drops (depending on 
the size of the dog) are given three times daily. 
Simple syrup of hypophosphites should be given in
