218 DISEASES OF CATTLE. 



HIM) LI>1BSBENT FORWABD FROM THE HIP BREECH PRESENTATION. 



This is an exaggeration of the condition last described., only the hocks 

 and stifles are fully extended and the whole limb carried forward 

 beneath the belly. (Plate xvn, Fig. 2.) The water-bags appear and 

 burst, but nothing presents unless it may be the tail. Examination in 

 this ease detects the outline of the buttocks with the tail and anus at 

 its upper part. 



The remedy, as in the case last described, consists in pushing the 

 buttock upward and forward with a repeller, the cow being kept stand- 

 ing and headed down hil! 7 until the thigh bone can. be reached, and used 

 as a lever. Its upper end is pushed forward and its lower end raised 

 until the joints becoming fully flexed, the point of the hock can be raised 

 above the brim of the pelvis. If necessary a noose may be passed 

 around the leg as far down toward 1 the hock as possible and pulled on 

 forcibly, while the hand presses forward strongly on the back of the leg 

 above. When both hocks have been lodged above the brim of the 

 pelvis the further procedure is as described under the last heading. 



If, however, the case is advanced and the buttocks wedged firmly into 

 the passages, it may be impossible to safely push it back into- the womb, 

 and the calf must either be dragged through the passage as it is or the 

 limbs or pelvis must be cut off. To successfully extract with a breech 

 presentation, the cow must be large and roomy and the calf not too 

 large. The first step in this case is to separate the pelvic bones on the 

 two sides by cutting from before backward, exactly in the median line 

 below and where the thighs come together above. This may be done 

 with a strong embryotomy knife, but is most easily accomplished 

 with the long einbryotonie. (Plate xx, Fig. 3.) The form which I have 

 designed (Plate xx, Fig. 1), with a short cutting branch jointed to the 

 in a in stem, is to be preferred, as the short cutting piece may be folded 

 on the main stem so that its cutting edge will be covered, and it can be 

 introduced and extracted Avithout danger. This is pushed forward 

 beneath the calf's belly, and the cutting arm opened and inserted in 

 front of the brim of the pelvis and pulled forcibly back through the 

 whole length of the pelvic bones. The divided edges are now made to 

 overlap each other and the breadth of the haunch is materially reduced. 

 One end of the cord may then be passed forward by means of a cord- 

 carrier (Plate xxi, Fig. 5), on the inner side of one thigh until it can be 

 seized at the stifle by the hand passed forward on the outer side of that 

 thigh. This end is now pulled back through the vagina, and the other 

 end passed through the cord-carrier and passed forward on the inner 

 side of the other thigh until it can be seized at the stifle by the hand 

 passed forward outside that thigh. This end is drawn back through 

 the vagina like the first, and is tied around the other so as to form a 

 running noose. The rope is now drawn through the ring until it forms 

 a tight loop, encircling the belly just in front of the hind limbs. On this
