or yellow. Urine is passed in a small jet, and with much 

 pain. 



Paraphymosis, the result of local swelling, is not uncom- 

 monly met with. 



General Symptoms, common to both Sexes. — There is a 

 muco-purulent discharge from the nose, and also a discharge 

 of tears from the eyes. The visible mucous membranes 

 are highly injected. The coat is dry, and the perspiration, 

 when breaking out, is offensive. Pressure over the lumbar 

 region causes pain, and the animal rests first on one hind- 

 limb and then on the other. The lymphatic glands in 

 the neighbourhood of the genital organs are engorged, and 

 those in the submaxillary space are similarly affected. The 

 animal is much debilitated, and walks with uncertain gait ; 

 the large joints are tumefied and painful ; the haunch 

 especially is affected. The pain causes the animal to lift 

 its leg while at rest, with a sudden jerk. 



The appetite is generally pretty good. Often one or both 

 liind extremities becomes paralyzed, and the entire muscu- 

 lar system becomes atrophied, especially the hind-quarters 

 and legs. 



The nasal membrane becomes yellow, and the buccal mem- 

 brane of purplish hue. 



The mammary gland may inflame and suppurate. During 

 the incubatory stage of this disease numerous cutaneous 

 tumours form on different parts of the skin. They are 

 small, of medium size, or large ; the small ones appear 

 and disappear suddenly ; the larger ones develop in twenty- 

 four hours, and disappear in from four to eight days. 



Albumen is present in the urine. 



Prognosis. — The disease usually lasts three or four months^ 

 but may extend over a period of three years. 



Contagion. — The disease is readily transmissible by copu- 

 lation. Mares take the disease more readily than stallions.
