that the symptoms were the same as in the above case. The 
same summer we had an imported Percheron stallion, four years 
old, die with this disease. This horse had been kept in the sta¬ 
bles and had not been used for breeding purposes for over a year. 
Prior to the time he took this disease he had what I call “ equine 
chorea” (St. Yitus dance); it was different from string-halt and 
almost like chorea in the human family. If he was surprised in 
any way, or if spoken to quick or sharp, he would dance back and 
forth in his stall, most generally crossing his front legs, and jerk¬ 
ing his hind ones up similar to that in stringhalt. In stringhalt 
only the posterior limbs are affected; but this horse was affected 
in everj' leg alike, and I have often noticed the muscles twitch on 
different parts of his body. This horse being subject to this ner¬ 
vous disease, which I have just described, it might be that it loca¬ 
ted itself in the muscles of the epiglottis and caused spasmodic 
action of them. In the other two cases, and in two more that I 
will hereafter describe, I am entirely ignorant of the cause, as 
will be seen later. 
In the fall of 1887 we had another stallion take this disease, 
which I have called u spasms of the muscles of the epiglottis.” 
This horse I brought in off of the range and took good care of 
him, but did not try to cure him in any way. He had his last 
spasm about last Christmas. I turned him out on the range with 
a bunch of mares last spring, and he has not shown any signs of 
a spasm since. 
Last August we had another stallion take this disease. He is 
in our stables now. He has had a number of spasms since we 
took him up, but generally they are not so hard as in the other 
four cases. On the 16th of last month he took a severe spasm 
that lasted fully thirty minutes; the sweat ran off of him in per¬ 
fect streams; there was a green froth came from his mouth, and 
he seemed to be in terrible pain. At the expiration of thirty 
minutes I performed the operation of tracheotomy on him, and 
he was immediately relieved. I performed the operation without 
casting him, as he was perfectly gentle and of a kind disposition. 
I was unable to secure the trachetomy tube that I have, so that 
when the head was changed from a low to a high, or a high to
