180 DISEASES OF THE HOESE. 



the anterior i^resenting part of the body may be skinned and cut off 

 as far back toward the pelvis as possible (see " Embryotomy "') ; then 

 nooses are placed on the hind fetlocks and traction is made upon these 

 while the quarters are pushed back into the Avomb. Then the re- 

 maining portion is brought away by the posterior presentation. 



ANTERIOR PRESEITTATION WITH BACK TURNED TO ONE SIDE. 



The greatest diameter of the axis of the foal, liks that of the pelvic 

 passages, is from above downw^ard, and when the fetus enters the 

 pelvis with this greatest diameter engaged transversely or in the nar- 

 row diameter of the pelvis, parturition is rendered difficult or impos- 

 sible. In such a case the pasterns and head may be noosed, and the 

 passages and engaged portion of the foal freely lubricated with lard, 

 the limbs may be crossed over each other and the head, and a move- 

 ment of rotation effected in the fetus until its face and back are 

 turned up toward the croup of the mother; then parturition becomes 

 natural. 



BACK or THE FOAL, TURNED TO THE FLOOR OF THE PELVIS. 



In a roomy mare this is not an insuperable obstacle to parturi- 

 tion, yet it may seriously impede it, by reason of the curvature of the 

 body of the foal being opposite to that of the passages, and the head 

 and withers being liable to arpest against the border of the pelvis. 

 Lubrication of the passage with lard and traction of the limbs and 

 head will usually suffice with or without the turning of the mare on 

 her back. 



In obstinate cases two other resorts are open: First, to turn the 

 foal, pushing back the fore parts and bringing up the hind so as to 

 make a posterior presentation, and, second, the amputation of the fore 

 limbs, after Avhich extraction wall usually be easy. 



HIND PRESENTATION WITH LEG BENT AT HOCK. 



In this form the quarters of the foal w^th the hind legs bent up 

 beneath them present, but can not advance through the pelvis by 

 reason of their bulk. (Plate XI, fig. 3.) The oiled hand introduced 

 can recognize the outline of the buttocks, Avith the tail and anus in 

 the center and the sharp points of the hocks beneath. First pass a 

 rope around each limb at the hock, then Avith hand or repeller push 

 the buttocks backAvard and upAvard, until the feet can be brought up 

 into the j^assages. The great length of the i^hank and pastern in the 

 foal is a serious obstacle to this, and in all cases the foot should be 

 protected in the palm of the hand Avhile being brought up over the 

 brim of the pelvis. OtherAvise the Avomb may be torn. AMien the 

 pains are too A^olent and constant to allow effective manipulation,
