 one-half inch on each side of the symphysis. Remove 

 carefully the pieces of bone thus isolated.

 termination of the oviducts. Each, in the small dogs, 

 is less than one one-half inch long, and is concealed 

 in a membranous capsule, which must be cut open to

 anterior end expands into a capsule surrounding the
