and purulent, of a reddish or greenish yellow colour, and exhales 

 a very disagreeable odour. 



The animal urinates often, and in small quantities, the 

 evacuation being preceded, accompanied, or followed by a more 

 abundant flow of the purulent discharge. 



The ejection of the urine causes a great amount of irritation, 

 and if the animal encounters any resisting obstacle behind her, 

 she will rub herself violently against it. 



Mares in foal generally abort about the third month. When 

 they carry the full period, the foals to which they give biyth are 

 usually dead, or die in a few hours. 



Stallion. — The manifestations of the symptoms in the stallion 

 are exceedingly uncertain. Sometimes they remain latent for a 

 very long period, and are only aroused by a repetition of the colt. 



The sheath then becomes the seat of an cedematous swelling,

In some cases the testicles, as far as external manipulation 

 can decide, remain perfectly healthy; in others they become 

 swollen, and the animal evinces great pain on the slightest 

 pressure. 



"When the penis is protruded it may present no alteration, or 

 it may (if destitute of pigment) have a reddish or marbled 

 appearance. In some cases spots of various diameters, and of a 

 deep violet colour, resembling ecchymosis, have been observed. 

 When the organ is in a state of complete erection the glans pepis 

 acquires a volume so great that its return is accomplished with 

 considerable difficulty. There is a hypersecretion of tl|e i;rethral 

 mucous membrane, which protrudes slightly from the meatus 

 urinarius, attains a somewhat globular form, and a crimson or 

 yellow colour. 



Cicatrices have been observed on the penis, in greatest
