the pasterns and feet so continuously and severely as to produce 
serious wounds. At other times it seizes its manger or anything 
else accessible with such savageness that the teeth are sometimes 
broken in their sockets. In other cases very peculiar nervous 
symptoms, epileptiform in their character, appear. At the ap¬ 
proach of a mare the stallion will be seized with a kind of 
spasmodic trembling; the muscles of the neck stand out in strong 
relief; the head is extended and shakes convulsively; the lower 
jaw moves from side to side; the eyelids, widely dilated, expose 
a large surface of the eyes, the schlerotica of which appears of a 
bright yellow color, while the organs themselves roll about in 
their orbits in a strange manner ; and the respiration is snorting 
and excited, the nostrils being widely expanded. These singular 
phenomena persist until the animal has gained sufficient energy 
to attempt copulation. At a later period the sight of a mare 
does not occasion more than a nervous trembling, which is also 
produced by the ingestion of cold water. 
The voice diminishes in sonorousness and strength, and can 
only be heard a short distance away, sounding husky and nasal. 
The diagnosis of the disease is more difficult in the stallion 
than in the mare, unless the local disturbance is accompanied by 
the secondary nervous symptoms already noted. Observation of 
the consequences resulting from coition, however, soon testifies 
as to the soundness of the animal; for if it has a chancre in the 
urethra it will transmit the disease to the mares it has been put 
to, though apparently in good health. 
As a rule, the progress of the disease is slow, and its termina¬ 
tion most frequently fatal, though the result cannot always be 
predicted with certainty. With some animals which are appar¬ 
ently much advanced in the malady—even as far as the paralytic 
stage—recovery will at times occur; while with others which are 
evidently only slightly affected, it progresses gradually to a fatal 
termination, in spite of all treatment. 
It is liable to intermissions and remissions or paroxysms. The 
swelling of the prepuce may be the only symptom for a long 
time, and this should arouse suspicion, especially if the horse has 
come from an infected locality; and particularly if there is weak-
