the growtli vintil the eye reaches the centre, when the male needle 

 is introduced at a right angle with it, and j^assed through the eye, 

 as in Fig. 234, to be drawn out on the opposite side of the tumor 

 carrying the ligatures with it (Fig. 235). 



In the second step of the operation, the passage of the male 

 needle through the tumor with the double ligature is completed, 

 and by the sej)aration of the needle from one of the threads, two 

 threads are left loose. The female needle is then pushed through 

 the tumor, when one of the threads is cut off (Fig. 236) ; the fourth 

 step being completed by having the female needle drawn back

through its original tract with the last threads or loop (Fig. 237), 

 and when the needle is finally sej^arated, it leaves the tumor divided 

 into four segments by four threads, whose extremities are drawn 

 and tightly secured by a single knot (Figs. 238, 239).
