EMBRYOTOMY 261 



Jorg, who reported this in 1818, remarks that it is impos- 

 sible to handle a knife inside the uterus without injuring it, on 

 account of the restlessness and straining of the mother. It, 

 therefore, would be best to slaughter the animal early. 



S. Fey in 1823 already recommended to repel the head and 

 push it downward toward the udder so that the nose rests 

 against the pubis, should the head resting on the fore legs 

 enter the parturient passage. The fore legs are removed with 

 a curved hook and knife by severing the skin around the 

 scapula. For extractions he uses forceps. In the handle of 

 the curved knife was a hole through which a rope was drawn. 

 Whenever desired by the operator, an assistant could pull on 

 it and assist in the operation. Fey further states that he saw 

 this knife used in 1812 in Cantons Glarus, St. Gallen, Zug and 

 Gasterland in dismembering calves within the cows without 

 the least injury to the mother. 



Giinther in 1830 describes in his work incisions as well as 

 the subcutaneous method in regard to the removal of a fore 

 leg. 



Huvelier in 1830 describes the removal of the fore limb of 

 a calf with the head turned to one side. He made a circular 

 incision through the skin in the middle of the shin-bone, split 

 it on the internal surface of the leg as far as the breast, sepa- 

 rated it with a bistoury, or better, with the hand, up to the 

 shoulder ; made a few rotary movements with the leg, corded 

 the fetlock, when the leg could be torn off by an assistant. He 

 introduced both hands into the uterus to exert counterpressure 

 on the foetus. 



Veret, quoted by Wit, in 1837 placed a rope around the 

 hindquarters of the parent above the hocks and had assistants 

 hold it. The leg of the young which is to be removed is 

 corded and fixed, the skin above the fetlock receives a circular 

 incision and is split upward. Now the skin is separated and 

 the leg pulled off by drawing on both ropes in an opposite 

 direction.

 otomy have appeared by Eyeliner, Baumeister, Franck, Harms;
