Symptoms .—They vary greatly in intensity, according to 
the temper of the animals and the quantity of the plant taken. 
The eyes are staring, sunken, glassy, pupil dilated, but able to 
contract when exposed to sudden light; horse cannot calculate 
distance, nor dimensions, nor nature of objects. When seeing a 
small object such as a bar or a rope, lying in his way, he will leap 
over it as if it were four feet high ; a barn near at hand seems 
to be far off, and one at distance, near-by. He will go headlong 
against a barn, a rock or any obstacle as if he were totally blind; 
he will let me get close to him, then suddenly run away and sud¬ 
denly stop, stare and look like a mad horse. He cannot see the 
manger with feed, although knowing its usual place; membranes 
of eyes injected and infiltrated. He walks with difficulty, shows 
a feeble and uncertain gait; lifts the legs up like a blind horse, 
will not back under any circumstances, wants to go in the oppo¬ 
site direction to which I pull him; cannot turn him around; 
when the rope pulls on the neck very hard, he grunts; seems to 
like the rubbing of the temporo-auricular muscles, and throws 
the head excitedly sideways when I pinch the base of the ears or 
behind and over the occipital bone. Cannot hear, seems deaf. 
The horse eats and drinks, but slowly, and at times stops masti¬ 
cating while the mouth is full of feed and some hay hanging par¬ 
tially outside—what the French call smoking his pipe—in sleepy 
staggers or immobility; seems to have no taste, as I have seen 
this horse and mule eat grain lively for three or four nights while 
two ounces of pulv. barbad. aloes were mixed with it; they never 
knew the difference. They are generally very excitable; if a 
quick motion is made before the animal, such as throwing up the 
arms, chicken flying over the fence, slapping of doors, etc., they 
are greatly frightened, and tremble all over, especially in muscles 
of head, neck and fore-legs. Sometimes a horse, and more so a 
mule, is suddenly seized as with mania, in which he gets very ex¬ 
cited and quite uncontrollable and even dangerous. I have seen 
the son of the house, standing three yards away from this old gen¬ 
tle family horse, stretch his hand towards the horse’s face, and 
hardly did he notice the hand in that position but the horse lay 
his ears, stretched out his head and neck, opened his mouth and
