486 ALPHABETICAL SUMMARY. 
HIDE-BOUND. 
Cause.—Neglect, or turning into a straw-yard for the winter. 
Treatment.—Liberal food, clean lodging, soft bed, healthy exercise, 
and good grooming. Administer, daily, two drinks, composed of: 
Liquor arsenicalis, half an ounce; tincture of muriate of iron, one 
ounce; water, one pint. Mix, and give as one dose. 
HIGH-BLOWING AND WHEEZING. 
Habits which admit of no remedies. 
HYDROPHOBIA. 
Cause.—Bite from a rabid dog or cat. 
Symptoms.—The horse is constantly licking the bitten place. <A 
morbid change takes place in the appetite. Eager thirst, but inability

slit through the skin is made; into that opening an armed trocar is 
driven. When there is no resistance felt, the thorax has been entered;
