588 DISEASES OF THE ORGANS OF GENERATION. 



gives of it is as follows : So long as the disease is confined 

 to the extreme end of the cord, it retains the appellation of 

 champignon ; when a sarcomatous change comes to affect the 

 entire cord as high as, or even bej^ond, the abdominal ring, 

 it then takes the name of scirrJms of the cord. Champignon 

 often er appears on the left than on the right side : not 

 owing to any particularity of structure, but simply, appa- 

 rently, to the greater difficulty of placing the clams upon 

 the left cord, owing to the right testicle being in the opera- 

 tor's way. One is apt not to be able to get the clams so 

 high up or so completely closed, and thus a portion of the 

 epididymis is very apt to become included, a circumstance 

 which is the usual cause of champignon. In some of these 

 cases the swelling runs up the cord, reaching even to the 

 loins, and becomes a source of great pain. The cord con- 

 tracts adhesions with the surrounding parts, and sometimes 

 itself turns to a cancerous mass. Now and then, in the 

 first instance, the scrotum partakes of the scirrhous tumefac- 

 tion : but this gradually subsides — seldom any cicatrization 

 or adhesion of it taking place. In general the aperture 

 remains open and discharging, and the end of the cord, 

 hanging loose within it,, continues ascending and descending 

 according to the action of the cremaster. Champignons 

 vary in their size and form : sometimes their largest part is 

 below, sometimes above. Soon after the commencement of 

 this disease, commonly between the sixth and tenth day, the 

 horse manifests stiffness in moving the limb of the affected 

 side. This dragging of one or both hind legs is evident on 

 his first leaving his box or stable : should it not diminish 

 or disappear from exercise, but, on the contrary, continue 

 or become worse after it, we have good reason to suspect 

 champignon ; for, as for the stiffness arising from the opera- 

 tion itself, that is dispersed by exercise. In proportion as 

 the swelling of the cord augments, the difficulty of progres- 

 sion increases, both the croup and loins manifesting it in 

 their movements : the horse also on occasions draws up his 

 leg while standing, becomes dull, tucked up, and falls away. 

 When the tumefaction of the cord is excessive, the animal
