bistouri cache is then introduced into the vagina, through the upper 

 wall of which an incision about 2 to 2 1 inches in length is made. 

 The bistoury is then laid aside, the vaginal speculum removed, and 

 the index and middle fingers of the right hand are passed through 

 the vaginal wound into the abdomen, where the left ovary is first 

 sought, and drawn into the vagina. The forceps for twisting off 

 the ovary are next introduced with the left hand, and whilst the 

 right hand, the thumb of which is covered with the metallic thumb- 

 stall, grasps the ovarian ligament, the left slowly rotates the forceps

until the ovary is freed. The right ovary is removed in a similar 

 fashion, the right hand, however, taking the place of the left, and 

 vice versa. No special after-treatment is required. Any blood which 

 may have passed into the vagina during operation is removed with 

 the hand or with a clean sponge. The vulva is washed once or twice 

 a day with a disinfecting fluid. Healing proceeds regularly and 

 without complication. No special difficulty is usually found in 

 operating, and after some practice the operation is not difficult. 



When this method became better known many modifications 

 were proposed by different operators. Colin incised the upper vaginal 

 wall near the os uteri with a guarded bistoury (Fig. 265), without using
