Russian authors that exposure to cold exercises a 

 great deal of influence in the development of this 

 affection, and observation has largely established 

 the fact of its greater prevalence during cold seasons. 



Symptoms of extra-scrotal champignon. This is 

 otherwise known in the terminology of some patholo-

 This form of it is usually of little account, as it may

 act of locomotion by causing pain in the cord, upon 

 which it drags more or less. It is not often or nec-

 excepting in cases of excessive suppuration, which 

 may sooner or later undermine the general health 

 by exhausting the stamina of the patient. 



If instead of showing its greatest development on 

 the surface of the scrotum, it occurs beneath it, a 

 greater or less degree of swelling will appear on one
