IXFLAMMATION OF THE FIIETHRA. 631 



says that a stallion may be thus affected from covering a mare 

 with a small vagina. In bulls, this affection is not at all uncom- 

 mon, but I am of opinion that it is more a result of injury due 

 to rashness in the act than to any other cause. 



Symptoms. — Frequent desire to urinate, the act performed 

 with difficulty ; frequent erection of the penis ; and a discharge 

 from the urethra. The genitals may afterwards swell, and ulcer- 

 ations may form upon the prepuce. 



Treatment. — The parts to be bathed with warm water, dressed 

 with mild astringents, which may be injected into the urethra, 

 and the animal to have mild aperients and the bicarbonate of 

 soda. If the case be chronic, the animal may have to be cast, 

 the parts examined, and all ulcerated surfaces dressed with the 

 nitrate of silver. 



Hutrel D'Arboval describes a disease in the horse simulating 

 syphilis, characterised by inflammatory irritation of the glans 

 penis, extending to the sheath, presenting a tense, shining appear- 

 ance, and giving rise to phymosis or paraphymosis. 



I have seen a condition similar to this originating in cancer 

 of the penis, as well as in those causes described by D'Arboval 

 in his dictionary. 



Causes. — According to D'Arboval, this form of irritation is 

 found in horses whose genitals are habitually dirty ; or arising 

 from accidents, or the introduction of foreign substances into 

 the sheath. 



Treatment. — Emollient fomentations to the parts; cleanli- 

 ness ; if abscesses form, they must be laid open, dressed with 

 weak carbolic acid lotions, and the general system modified by 

 mild cathartics, bicarbonate of soda, and demulcent drinks, 

 such as linseed tea. In the more chronic cases, it may be 

 necessary to apply the nitrate of silver, or even to amputate 

 the penis. 



The Vesicul^ Seminalis are but very rarely the seat of disease ; 

 but I have met with instances in young bulls, where they have 

 been distended by an accumulation of epithelium, imperfect 

 semen, and dehris. The symptoms are, pain and straining in 

 defajcation, and difficiilt micturition. On exploring the rectum 

 to discover the cause of these symptoms, a fluctuating tumour 

 will be discovered upon one, perhaps both, sides of the pelvis, 

 pressing upon the urethra and neck of the bladder.
