2G0 CONTAGIOUS DISEASES. 



ficial ulcers, caused by tlie destruction of vesicles whicli had 

 formed on this organ. 



After each evacuation of urine, effected after a number of 

 painful efforts, and expelled in a small but continuous jet, the 

 animal stamps violently, and whisks its tail, as if the passage 

 of that fluid through the urethra had caused a considerable 

 amount of pain. 



In concluding the local symptoms, it may be remarked that 

 paraphymosis is not an unfrequent result of the local swellings. 



GENEKAL SYMPTOMS. 



As these are the same in both sexes, it would be useless to 

 consider them separately. 



A more or less abundant discharge of a muco-purulent matter 

 from the nostrils, and of tears from the eyes, sufficiently indicate 

 that there is a general affection of the mucous membranes, of 

 which those visible are highly injected. 



The lymphatic ganglia, not only in the vicinity, but also those 

 in the submaxillary space, are engorged. 



The appetite is generally good, and the food thoroughly digested ; 

 nevertheless the animal gradually falls off in condition, and, ,to 

 use a common expression, becomes hide-bound, with a dry and 

 staring coat ; the perspiration gives off a most offensive odour. 



The sensibility of tlie lumbar region is so great that in some 

 cases ordinary pressure Avill almost bring the sufferer to the 

 ground. The presence of albumen has been observed in the urine. 



General weakness soon manifests itself by the weight of the 

 hind quarters being thrown alternately and incessantly from one 

 posterior extremity to the other. 



When the animal is caused to walk the gait is very uncertain, 

 and the sudden flexion of the joints is sometimes so great as to 

 cause it to fall. There is a considerable tumefaction around 

 the larger joints, and especially around that of the haunch. This 

 tumefaction is very painful, and causes the animal while at rest 

 to hft its leg with a sudden jerk, after the manner in which a 

 horse with stringhalt behaves when caused to move suddenly, 

 but it places it more carefully on the ground again than does 

 the latter. When both limbs are affected, this movement is 

 manifested alternately. These symptoms of lameness are some-
