MALADIE DU COIT. 
349 
epileptiform convulsions in the stallion, when approached by a 
mare, in which the stallion is seized with spasmodic trembling, 
rigidity of the muscles of the neck, convulsive shaking of the head, 
dilatation of the eyes and nostrils, rolling of eyeballs, etc. In one 
stallion (VIII) there was a marked loss of voice, an excessively 
glutinous nasal discharge, large nodulated submaxillary lymphatic 
glands, and distinct superficial erosions on the nasal mucous 
membrane. 
Pruritis is usually more marked in the stallion than in the 
mare, causing him to rub or bite violently the feet, pasterns, or 
other affected parts, producing large unhealthy sores. The ellip¬ 
tical welt-like swellings of the skin are usually also more marked 
in the stallion than in the mare. There is also a strong tendency 
to suppuration of the inguinal and scrotal lymphatic glands. The 
inguinal glands, in some cases in the present outbreak, were the 
seat of extraordinarily large abscesses, in some cases filling up the 
entire groin and causing excessive swelling of the scrotum, extend¬ 
ing down almost to the hock joints, and when the abscesses finally 
ruptured, they discharged near a gallon of thick, curdled pus. 
The lymphatics of the sheath and scrotum were still more prone to 
suppuration, but the abscesses were tardy, indolent, and usually 
not very extensive, but their presence frequently caused extensive 
indurations, pushing the testicle upwards toward the inguinal ring 
and occupying the ordinary position of the testicle, could be readily 
mistaken for that organ. In one stallion (XVIII) there is marked 
paralysis and atrophy of the extensor muscles of one forearm (ex 
tensor metacarpi magnus and extensor pedis), which may be due to 
the disease, but more likely to accidental injury. 
Course and termination. The course of the disease is very 
prone to remissions and exacerbations, progressing slowly in the 
majority of cases to a fatal termination. 
Recovery may and does occur even after extreme emacia¬ 
tion and when paralysis has been so complete that the animal could 
not rise without assistance. 
The duration of the disease may extend from three months to 
as many or more years, and recovery, either apparent or real, take 
place at any intervening time.
