that have small sunken eyes (“ pig-eyes”). Harness-horses are more liable 
to it than saddie-horses, and young ones more than the older. 
Symptoms.—F low of tears; lining attached to the ball is red; in the 
morning the eye is almost closed and full of tears; eyelids swollen; pain from 
the light; great reluctance to allow the eye to be opened; corner of the 
eye red; the transparent part in front grows muddy and opaque; pupil 
very small; iris dim, speckled with white, covered with lymph, pus or 
blood; hot, dry mouth and quick pulse; constipation; scanty urine; on the 
third to the sixth day congested blood-vessels run into the edges of the 
ransparent portion; later still this naturally transparent portion passes from a 
yellowish-white to a greenish or brownish; sometimes the crystalline lens be- 
comes opaque and cataracts form; the iris may be affected with inflammation in 
frequent attacks and great irritability, though blindness may not soon inter- 
vene; occasionally the interior of the eye becomes yellow and muddy, the eye 
then shrinking away. In favorable cases the symptoms begin to disappear 
from the fourth to the tenth day, the eye becoming healthy, An attack 
may last from four days to six weeks, each one being shorter than the pre- 
ceding. Apparent recovery is often interrupted by a relapse or change of 
the attack to the othereye. Between attacks the eye may appear well, but it 
is not; the eyelids may form nearly or quite a right angle; the iris may 
remain contracted and lose its luster. An attack will recur upon a return 
to the usual food, upon exposure to wind, cold and rain, or upon a return to 
a dirty or badly-venti'ated stable. Traces will almost invariably remain 
after a so-called cure; hence the importance of critically examining the eye 
before purchasing. 
TREATMENT.—Aconite should be given in alternation with belladonna 
every three or four hours at the beginning of the disease if fever is present, 
tears abundant, eyelids swollen, and the eye blood-shot. Continue the 
belladonna after the subsidence of the fever-symptoms which demand 
aconite, if the membrane of the eye remains red, tears abundant, and local 
inflammation stubborn, Throughout the whole attack, until a cure is 
effected, apply to the eye a lotion of belladonna, two grains of the extract 
to one ounce of water; or bind on the eye a cloth soaked in the same. 
Euphrasia has effected speedy cures, used in the same manner as a wash, 
and given internally. Mercurius corrosivus should be alternated with 
belladonna when the eye is brownish or whitish, and as long as the humors 
are dim or the naturally transparent part is opaque. When there is a low state 
of the system, with a weakened constitution, and when recurrence is sus- 
pected, give arsenicum. Some cases require a general tonic treatment, and 
nux vomica, iron, ginger or Peruvian bark will be found useful. Surgical 
measures are sometimes necessary, especially for inflammation and hardening
