extremities come out by the same openiag (Fig. 243), whUe a sec- 

 ond thread, f f, is free between the superior and the two lower 

 thirds of the tumor (Fig. 244). 



The manipulations for the superior third of the growth are 

 repeated for the lower third, with another thread, and the middle 

 third is then surrounded by two parallel threads A, B and 0, D 

 (Fig. 245).

Both of these two threads are passed into the curved needle, 

 and it then becomes easy to carry under the sMn the extremity of 

 the thread B to the opening D, and the thread A to the openiag 

 C, where it will be tied to thread B. All the threads A, B, C, D 

 will thus form a loop embracing the middle third of the growth, 

 as the other threads wiU surround the upper and the lower thirds. 

 AH the ligatures can be then tied to the required degree and the 

 operation is completed (Figs. 246, 247).

 upon the base of the tumor is in place, it must be tied more or
