126 THE DISEASES OF THE HORSE. 



HYSTERIA 



Is usually caused by sexual heat. Sometimes it is the 

 result of nervous, convulsive, or spasmodic affections. 

 Breeding is perhaps the best remedy for sexual heat. 



Symptoms. — Clenching jaws, grinding teeth, squint- 

 ing; unrelaxing spasms alternated with relaxing; kick- 

 ing, stamping, and other signs of nervous excitement; 

 sometimes rapid opening and closing of vulva, &c. 



INFLAMMATION OF THE TESTICLES. 



Remedy. — Fomentations, anodynes, a dose of physic, 

 support testicle. Iodine liniment; potassium iodide in- 

 ternally. Tubercular form intractable ; castrate in early 

 stage. For doses, see pages 1-3 to 29. 



PROTRUDED PENIS (PARAPHYMOSIS), 



Is sometimes caused by loss of power (paralysis). In 

 the stallion there are many other causes, such as excessive 

 copulation, friction before copulation, by rubbing against 

 female; kicks and other injuries; introduction into anus; 

 attempt to cover a ( ringed mare ; ' irritating substances 

 (medicines) in prepuce ; warts, &c. 



Remedy. — Amputate if necessary. 



Confined (unprotrudable) Penis (phymosis) is very 

 rare. 



Amputation of the Penis is practicable, and is some- 

 times resorted to as a cure for warts, ulcers, cancer, pro- 

 trusion, &c. 



Cancerous Tumor of the Vulva is recorded. As it 

 did not yield to treatment, but gradually enlarged till it 

 filled "two-thirds of the vulva," the mare was destroyed. 

 The tumor existed nearly three years.
