cow on its other side in the same direction ia which the 

 twist has taken place. If the womb is not distended by 

 decomposition of a dead foetus, nor attached to adjacent 

 parts by inflammatory exudations the untwisting is easily 

 effected, though several successive attempts may be requisite 

 to secure it. Suddenly constriction around the wrist gives 

 way, the water-bags enter the passage and delivery is easy. 



Polypus est the Yagina. A tumor growing from the 

 walls of this passage is another obstacle to parturition. . By 

 examination its point of attachment is found, and it should 

 be slowly twisted off or, better still, removed by an ecraseur, 

 an instrument with a pitch-chain which is gradually tight- 

 ened so as to cut through the parts without loss of blood. 



Deopsy of Womb oe Abdomen, and Ovebdistended

Maxims foe Assisting in Dutioult Paetueition. Never 

 interfere too soon. Let the water-bags burst spontaneously 

 when they have fulfilled their purpose of dilating the pas- 

 sages. .If there is no mechanical obstacle, let the foetus 

 be expelled by the unaided efforts of the mother. Never 

 insert the arm for any purpose without first smearing it with 

 oil or fresh lard. When the water-bags have ruptured 

 and the pains have continued for some time without any 

 presentation, examine. When one fore foot only and the 

 head, or both fore feet without the head, or the head with- 

 out the feet, or one hind foot without the other appears, 

 examine. Whatever part is presented should be secured 

 by a cord, with a nmning noose, before it is pushed back 

 to search for the others. In searching for a missing 

 member the dam should be placed with her head down 

 hill and if recumbent should be laid on the side opposite 

 to that on which the limb is missing. Even if the missing 

 member is reached do not attempt to bring it up during a 

 pain. Violent straining may be checked by pinching the 

 back. If the passages have lost their natural lubricating
