the hip. Sometimes this latter method may be necessary. This 

 position is likewise easily intelligible, and is therefore not 

 illustrated by a picture. 



{h.) The presentation now to be described is illustrated by 

 the two figures numbered 92 and 93 respectively, the first of 

 these pictures showing the position itself, and the second 

 depicting the successful accomplishment of what the veterinary 

 surgeon should strive to bring about. 



In Fig. 92 the foetus is seen to be lying with its head directed 

 towards the chest of the cow, having its hinder parts, namely 

 the breech and the tail, alone presented and pressed against the 

 brim of the pelvis, and the hind-legs doubled up under the 

 body. It is clear that the hind-legs must be brought into the 

 vaginal passage, and in order to effect this adjustment an instru- 

 ment invented by Professor Simonds should be used. By means 

 of this instrument a cord is passed round each thigh, then the 

 body of the foetus is pushed forwards by the aid of the crutch, 

 and the loop is passed down to the fetlocks. Then, the pressure 

 being still applied, the feet are drawn by means of flexure of 

 the hocks and other joints into the vaginal passage, and removal 

 is then eflfected. This method may be described somewhat as 

 follows : — 



The instrument sketched in Fig. 92 consists of a curved 

 piece of steel htiving an aperture at one end, to which a small 

 cord is attached. At the other a female screw is placed, and 

 this admits of its junction to a whalebone staff, and between the 

 two another opening exists, into which a stronger cord is 

 inserted. Taking the staff with the two cords in his hand, the 

 operator is to pass the instrument between the thighs of the 

 calf, and push it in front of the stifle-joint, and then with a 

 turn of the wrist to direct the small cord outwards. An assistant 

 holding the instrument, the hand of the accoucheur is now to 

 be introduced and directed to the front part of the stifle-joint, 

 when the cord can be readily grasped and brought out. Thus 

 the limb will be embraced between the two cords. The whale- 

 bone staff" is then to be detached, and the smaller cord to be 

 run through a noose at the free end of the larger one, when, by 

 drawing the smaller cord, the carved part of the instrument will 

 travel round the limb, bringing with it the larger cord, and thus 

 a looped ligature will be placed upon the leg above the hock.
