Treatment. — Subjects so affected should be cast and 

 tied and the area of operation prepared as for castra- 

 tion. An elliptical incision is then made in the scro- 

 tum, to include the castration scar. By careful dissec- 

 tion the cyst-like enlargement is separated from the 

 tissues without cutting through its wall, up to a point 

 where it is attached to the cord, and ablation is then 

 effected by means of the emasculator or ecraseur. This 

 opei-ation is a very simple one if the wall of the cyst 

 is not perforated, and when this enlargement has been 

 removed completelj^ with the amputation of the cord 

 at or above the site of adhesion of the vaginal timics, 

 recurrence ol' this affection is not possible.
