(1) Contraction of the mouth of the vessel (see B, Fig. 11) ; (2) 

 retraction of the vessel into its sheath (see C, Fig. 11) ; (3) clot 

 formation (see D, Fig. 11) ; (4) syncope.

The function of the emasculator is to assist nature in prevent- 

 ing primary and secondary hemorrhage. This is done by crush- 

 ing the cord which crimps or closes the spermatic artery to the 

 extent of making the field more favorable for clot formation. 

 Never place an emasculator on a cord in any position except at 

 right angle to the cord. (See Fig. 12.) If the cord is severed at 

 any other angle (see Fig. 13) fatal hemorrhage is liable to occur. 



Warning — Before beginning to operate always carefully ex- 

 amine the animal for inguinal and scrotal hernia (''rupture"), 

 abnormalities in development and diseases of the scrotum testicle 

 and cord. It is also well to look out for constitutional diseases 

 which would have a tendency to endanger the life of the animal 

 or interfere with convalescence. Never castrate if the animal is
