the other animals which were operated at the same time. 
The operation was that of torsion, and from the first step 
the difficulties began. The excessive power of contraction 
of the cremaster, not in proportion to the state of the animal, 
was overcome by gentle slaps on the face, and once the in¬ 
guinal sheath open, the cord, very large, was seized with the
