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 so'^^ket 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 hock side of the ring, to the oppo.ite, an 1 then knotted 

 ?o that the greater the R-rce applied the firmer it will hold. 



Presentation of one Hind-Limb alone is recognised by 

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

 mistaken for the knee. The same principles are applied here.. 

 Noose the presenting limb, and pushing back upon it and the 

 buttocks, bring up first the hock and then the fo'.t, 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 ham- 

 strings, and, leaving the hock bent, to straighten out the limb 

 above this and extract in this position. 



Presentation of the Buttocks is to be recognised by the 

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

 the vulva. The process of extraction does not differ from that 

 last described, buc in very powerful mares the pains may be so 

 violent and constant that it is i'tipossible 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 Superfluous Limbs have 

 to be removed on the same general principles, but space forbids 

 their further notice here. 



Water in the Head is often an insuperable barrier to 

 delivery, to be easily recognised by manual examination, and 

 as readily relieved by plunging a knife through the membranes 

 and evacuating the liquid. 



Water in the Abdomen is equally frequent and to be 

 obviated in a sin;ilar manner.
