I found the mare greatly agitated, the whole body tetanized, 
with constant clonic twitchings, spasmodic movements of the 
limbs, hurried, labored respirations, nostrils widely dilated, 
visible mucous membranes of a dark livid hue, firm trismus, 
and profuse sweating. When on her feet she could not stand 
still, but continually moved about involuntarily and so very 
uncertainly that she could scarcely be approached with safety. 
The perspiration was so profuse that it streamed from the de¬ 
pendent parts of her body, the nose was poked out, the head 
elevated, the back arched, the tail erected, giving the entire 
body the posture assumed in severe tetanus, but the well- 
marked protrusion of the membrana nictitans seen in the lat¬ 
ter disease was wanting. The animal would lie down fre¬ 
quently, and usually on the sternum, in which position she 
became more tranquil and apparently obtained some relief; 
at other times she lay prostrate on her side, in severe convul¬ 
sions, the legs all rigid, so that the upper feet did not touch 
the ground, but projected in a straight line from the body. 
The spasm of diaphragm was so violent in this case that even 
when the mare was lying on her sternum her whole body 
shook very markedly at each contraction, and when standing 
fifteen or twenty feet distant a loud thumping noise could be 
heard, emanating from the chest, like violent palpitation of 
the heart, but upon close examination it was found that it 
bore no relation to the heart-beat. 
With great difficulty, owing to the uncertain convulsive 
movements of the animal, I drew about three gallons of blood 
from the jugular. This was followed by heavy and repeated 
doses of fluid extract belladonna and cannabis indica, about 
i]/2 drachms of each every hour. 
My prognosis was very unfavorable, as death seemed im¬ 
minent. After twelve to fifteen hours the symptoms rapidly 
abated, and within twenty-four hours after my visit she was 
apparently in her usual health. 
In another case—the last to come under my observation— 
a high grade draft mare of vigorous constitution, and with a 
well nourished, healthy foal, some fifteen to twenty days old, 
at her side, was taken from the pasture for the first time since
