 Mika. Mikulicz's: I. For the removal of tonsillar 

 tumors ; it is done by an incision through the neck, 

 the cut extending from the mastoid process downward 

 and forward as far as the great cornu of the hyoid 

 bone ; the ascending ramus of the jaw is then resected 

 and the wall of the pharynx is divided ; a preliminary 

 tracheotomy is performed. 2. For tarsectomy ; the 

 same as Wladimiroff s operation, but independently 

 designed. Miller's, for amputation of the penis ; the 

 flap is cut from below. Milne's, for internal urethrot- 

 omy ; it is done with a special dilating urethrotome. 

 Miner's, for the removal of an ovarian tumor; enu- 

 cleation when removal cannot be effected in the usual 

 way, owing to absence or shortness of the pedicle, 

 or to adhesions. Miot's, for chronic non-suppurative 

 middle-ear inflammation ; the stapes is exposed, either 

 by excision of the upper posterior part of the mem-
