 the fact of its greater prevalence during cold seasons.

 ing mass, of a red color, vaiying in size, its growth,

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

 easily be removed before it has attained to trouble-

 tions, however, it may interfere materially with the 

 act of locomotion by causing pain in the cord, upon 

 wiiicli 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 

 or both sides of the inguinal region, the swelling be-
