DISEASES OF 1HE GENERATIVE ORGANS. 211 



Then during the next pain, by pushing back the body and continuing 

 to operate the forearm as a lever, a still farther advance' may be made. 

 As the knee is brought up in this way, the hand is slid down from the 

 * 1 1. \v ;i rd the knee, which is finally brought up over the brim of the 

 pelvis and into the passage. It is now corded at the knee, and the 

 subsequent procedure is as described in the last article. In a large 

 roomy cow with a small calf the latter may pass with one or both fore 

 legs bent back, but this is a very exceptional case, and as early assist- 

 ance is the most successful, there should never be delay in hope of such 

 a result. 



ONE FORE LIMB CROSSED OVER THE BACK OF THE NECK. 



This is a rare obstacle to calving, but one that is not altogether 

 unknown. The hand introduced into the passage feels the head and 

 one fore foot, and farther back on the same side the other foot, from 

 which the limb can be traced obliquely across the back of the neck. 

 (Plate xvi, Fig. 3.) This foot projecting transversely is liable to bruise 

 or tear the vagina. If still deeply engaged in the vagina, it may be 

 seized and pushed across to the opposite side of the neck, when the 

 presentation will be natural. 



THE HEAD BENT DOWN BENEATH THE NECK. 



In this case, with drooping belly and womb allowing the brim of the 

 pelvis to form a ridge, the advancing calf having unduly depressed its 

 nose strikes it on the brim of the pelvis, and the neck advancing, the 

 head is bent back and the poll and ears either enter the pelvis or strike 

 :i x ainst its brim. The two fore feet present, but they make no progress, 

 and the oiled hand introduced can detect no head until the poll is felt 

 at the entrance of the pelvis, between the fore arms. The two fore feet 

 must be fixed with running nooses, and dragged on moderately while 

 the oiled hand seeks to bring up the head. The hand is slid down over 

 the forehead and brim of the pelvis until the nose is reached, when it 

 is passed into the mouth, the muzzle resting in the palm of the hand. 

 The legs are now pushed upon, and in the space thus gained the muzzle 

 is drawn up so as to enter it into the i>elvis. In doing this the operator 

 must carefully sec that the mouth does not drop open so that the sharp 

 front teeth cut through the floor of the womb. Should this danger 

 threaten, the hand should be made to cover the lower jaw as well. The 

 lessened security of the hold is more than compensated by the safety 

 of the procedure. With the nose in the pelvis it has only to be drawn 

 forward and the parturition is natural. 



HEAD BKNT DOWN BENKATH THE BHEAST. 



This is an exaggerated condition of that last named. The head 

 arrested by the bi im of the pelvis and already bent back on the neck, is
