There may be noted also an inflammation of the skin which causes 
the animal to rub itself frequently, while spots may be present on the 
hind legs and in the region below the genitals, as a result of the 
discharge from the penis or vagina coming into contact with the skin 
and causing a destruction of the coloring matter. 
The temperature of the animal seldom goes above 101° or 102° F. 
Labored breathing is occasionally noted, and in some cases the glands 
under the jaw swell and a discharge appears from the nostril, simu- 
lating glanders. When paralysis of the hind limbs appears it usually 
progresses rapidly. The 
horse goes down, is unable to 
rise, and dies in a short time 
from nervous exhaustion. 
Until the last, however, the 
appetite remains good, and 
the stallion shows a desire for 
the mare, although service is 
impossible. 
POST-MORTEM LESIONS. 
The post-mortem lesions 
may vary considerably, de- 
pending on tjie severity of 
the initial attack of the dis- 
ease and the length of time 
the animal has been affected. 
The following lesions may be 
noted, but their presence and 
extent are governed by con- 
ditions described. 
In the mare the lining 
membrane of the vulva and 
vagina shows swelling and 
gelatinous infiltration, to- 
gether with considerable con- 
gestion of the blood vessels. 
The lining of the womb is 
thickened and corrugated, and sometimes ulcers are present. The 
whole internal lining of the organ may be orange colored, may be cov- 
ered with a discharge of mucous pus, and occasionally may show small, 
irregular, yellowish patches. The ovaries are frequently involved, 
and may show hemorrhages and a large blood clot in their interior. 
AVhere the discharge from the genital organs has come into contact 
with the skin there are irregular-shaped whitish spots. 
In the male the penis is usually enlarged, although in some cases 
normal in size. It frequently contains ulcers or scar tissue on its 
surface or in the urethral canal. The sheath is also swollen and the
