Thus, in each anterior or posterior presentation, with the back of the calf turned downward or to one side, the case may be complicated by the bending back of one or more members as a whole or at the joint just above the shank bones (knee or hock). So also in such anterior presentation the head may be turned back. _Head and fore feet presented--Back turned to one side._--The calf has a greater diameter from above down (spine to breastbone) than it has from side to side, and the same is true of the passage of the pelvis of the cow, which measures, on an average, 8-7/10 inches from above downward and 7-9/10 inches from side to side. Hence the calf passes most easily with its back upward, and when turned with its back to one side calving is always tardy and may be difficult or impossible. The obvious remedy is to rotate the calf on its own axis until its spine turns toward the spine of the cow. The operation is not difficult if the body of the calf is not yet fixed in the passages. The presenting feet are twisted over each other in the direction desired, and this is continued until the head and spine have assumed their proper place. If the body is firmly engaged in the passages the skin of the whole engaged portion should be freely lubricated with lard, and the limbs and head twisted over each other as above. The limbs may be twisted by an assistant when the head is manipulated by the operator, who drags on the rope turned halfway round the limbs and assists in the rotation with his other hand in the passages.
