If it is decided to remove the entire head at once, it may be skinned from the front of the eyes back to behind the lower jaw below and the poll above, then cut through the muscles and ligaments around the first joint and pull the head away, assisting, if need be, in the separation of the head by using the knife on the ligament of the joint. If the calf is a double-headed monster, the skinning of the head must be carried backward until the point has been reached where both heads branch from the single neck, and the separation must be made at that point. The muscles and ligaments are first to be cut through; and if the part can not then be detached by pulling, the bodies of the vertebrÊ may be separated by passing the knife through the joint. The second head may now be secured by a noose around the lower jaw or hooks in the orbits and brought up into place, the body being pushed back toward the other side by a repeller, so as to make room. It should be added that, except in the case of a double-headed monster, or in case of the head protruding or nearly so, and one or both fore limbs presenting, it is rarely desirable to undertake amputation of the head. The space desirable in the passages can usually be obtained by the much simpler and easier procedure of removing one or both fore limbs. _Amputation of the hind limbs._--This is sometimes demanded on the one extended limb when the other can not be brought up and delivery can not be effected; also in case of monsters having extra hind limbs; when the calf is dead, putrid, and bloated with gas; and in some cases of breech presentation, as described under that head.
