COMPLETE EMBRYOTOMY 283 



upper fore leg is subcutarteously removed as already described. 

 When traction is now exerted on the other fore leg one half of 

 the calf will project at the vulva, followed by amputation of 

 the neck, fore leg and breast. Further manipulations with 

 the knife become possible when now two persons pull on the 

 skin of the calf. Next, the last ribs, belly, dorsal and lumbar 

 region and thigh are skinned by hand. Kruyt uses for this 

 purpose linseed meal paste in large quantities, reducing the 

 labor of separating the skin by hand to a minimum. The ribs 

 are cut with the sharp hook along the vertebral stalk and 

 extracted with the forceps. 



After removal of the viscera, only the hind parts and the 

 whole spinal column remain. When the back has been well 

 skinned, the forceps can be passed as far as the pelvis, and the 

 whole vertebral column cut off at once. 



The muscles along the lumbar region and the broad pelvic 

 ligament of the upper side are cut with the small sharp hook, 

 and the internal angle of the ilium and the underlying wing of 

 the sacrum is taken off with Hinze's obstetrical saw. After 

 the saw has passed through the bones, the large hook is 

 passed through the same cut to sever any soft tissues still 

 adhering. He incises the muscles around the cotyloid cavity 

 with a small hook, pushing the instrument between the femur 

 and pelvis to cut the soft parts as deeply as possible. 



Into this incision is passed the large hook, pulling from 

 within outwards, displacing the head of the femur and rup- 

 turing the round ligaments at the same time. 



In order to split the ischio-pubic symphysis he employs 

 a sharp heart-shaped spatula. To insert the instrument he 

 locates the proper spot with the nail of the thumb. With a 

 light blow upon the handle the instrument is driven into the 

 cartilage; twisting it to the right and left, the symphysis is 

 separated. The disarticulated half of the pelvis is extracted 

 with a rope or forceps. 



Traction is next exerted upon a rope placed around the 

 femur and the balance of the calf delivered. 



This method only requires one man for traction. The
