VESICULAR ERUPTIONS ON THE PENIS. 



Phlyctenoid vesicular eruptions on the penis are some- 

 times met with in stallions, and are by some regarded as a 

 non-malignant species of chancre. It is a pellucid vesicle 

 containing a serous fluid, which sometimes also occurs in 

 young stallions that never have been used for service. The 

 vesicles, after bursting, leave small ulcers, which readily 

 heal when cleanliness of the parts is attended to. Otherwise 

 they may become more or less aggravated and incapacitate 

 the animal for service. During the eruption of the vesicles 

 more or less local pain and inflammation exists. An animal 

 thus affected should not be used for service. Treatment con- 

 sists in frequent bathing, first with a Solution of one part of 

 Goulard's extract and ten parts of water. When inflamma- 

 tion has subsided use frequent applications of a solution of 

 alum in water, and cleanse the parts with soap and water. 

 In aggravated or protracted cases use frequent bathing with 

 a solution of one part of chloride of lime in twelve to fifteen 

 parts of cold water. Internal remedies are generally not 

 necessary. 



FOUL SHEATH. 



Accumulation of sebaceous matter, cuticular desquamma- 

 tion and other deposits within the cavity or folds of the 

 sheath often cause considerable local irritation and conse- 

 quently more or less swelling of the sheath. This latter 

 condition may also be due to accumulation of serum in the 

 areolar or subcellular tissue, in consequence of local or gen- 

 eral debility, or from some constitutional cause; and the 

 swelling of the sheath, from whatever cause, may exist to 

 such an extent as to impede the extension or protrusion of 

 the penis, and cause the animal to acquire the babit of dis- 

 charging the urine within the sheath. The irritation 

 already existing within thus becomes aggravated; decompo- 

 sition of the accumulated greasy substances is thereby en- 

 hanced and putrescence and fetor ensue. During summer 

 this may attract flies, which "blow" the parts and cause 

 accumulation of myriads of maggots within the sheath. 

 Continued irritation may produce more or less local inflam-
