MALA Pit! IHT COlf. 
The mucous membrane of the vagina and the vulva is also 
modified, and assumes a marbled appearance ; the labia open, and 
the hypertrophied clitoris appears in the inferior commissure, all 
having a lardaeeous consistency ; while the vaginal orifice, de¬ 
formed and gaping, resembles the anus of an old horse. 
Mares that have conceived usually abort towards the third or 
fourth month of gestation ; though this action does not stay the 
progress of the malady. Should the full term of pregnancy be 
reached, the foal produced is dwarfed, badly formed, and either 
dead at birth or dies soon afterwards. The exceptions to this 
rule are rare. 
The emission of urine gives rise to pruritis, and occasions 
uterine excitement at the commencement of the malady ; a> the 
latter progresses the urine becomes thicker and viscid, and 
charged with salts, which are deposited on the labia of the vulva, 
in the navicular fossa, and on the clitoris. 
These local symptoms are not present in every case with the 
same intensity, the individual differences being often very great; 
it sometimes even happens that they are scarcely noticeable. 
The general symptoms appear in the following sequence : Emaci¬ 
ation, lameness, nervous derangement, paralysis and marasmus. 
If recovery takes place, it is only in those cases in which the 
disease is little developed; then the morbid phenomena diminish, 
the wasting stops, the vigor returns, and the other symptoms 
quite, or nearly disappear ; though there often remain paralysis 
of the labia of the vulva, with hypertrophy of the vaginal mucous 
membrane. 
The recovery, which is rare, may take place after seven, eight 
or ten months, or even longer. Lafosse, in his experiments, saw 
a case recover after nineteen months’ continuance. 
The duration of the malignant form is extremely variable. 
Heath has occurred in five months, a year, and even two years ; 
*but frequently before this interval has elapsed the animals are 
killed, or intercunent maladies hasten the disease to a fatal ter¬ 
mination. 
Inflammation of the mammae is frequent, terminating in sup¬ 
purationalso circumscribed inflammations of the skin. In weak
