pulling the limbs forward into the passage, push back the 

 body in such a way as will favor the advance of the head. 

 li the ear is reached the head may be pulled by it, till the 

 socket of the eye can be gained, and the body being still 

 pushed back the nose can soon be seized and brought up 

 Often it is necessary to insert a hook into the eye socket' 

 or between the branches of the lower jaw, so that more 

 force may be exerted. The ring in this case should be 

 turned at right angles to the hook, and a cord passed from 

 the hook side of the ring, to the opposite, and then knot- 

 ted so that the greater the force applied the firmer it wiU 

 bold. 



Peesentation of one hind limb alone is recognized by 

 examining it as far up as the hock, which cannot possibly 

 be mistaken for the knee. The same principles are ap- 

 pUed here. Noose the presentiag limb, and pushing back 

 upon it and the buttocks, bring up first the hock and then 

 the foot, bending all the joints to their utmost. In the 

 cow success can usually be counted on, but the long hind 

 shanks of the foal often prove an insuperable obstacle, and 

 it becomes needful to cut the hamstrings and, leaving the 

 hock bent, to straighten out the limb above this and 

 extract in this position. 



Peesentation oe the buttocks is to be recognized by 

 the rounded mass, with the tail and beneath it the anus 

 and perhaps the vulva. The process of extraction does 

 not difier from that last described, but in very powerful 

 mares the pains may be so violent and constant that it is 

 iai possible to bring up even the hocks, and the limbs have 

 to be separated at the hip-joint and extracted separately, 

 after which the trunk will come easily. 



Double heads and bodies and supeeeluous limbs have 

 to be removed on the same general principles, but space 

 forbids their further notice here. 



Watee in the head is often an insuperable barrier to 

 delivery, to be easily recognized by manual examination
