 dependable in controlling hemorrhage, hence is unsafe and un- 

 satisfactory. Fig. 5 illustrates an emasculate >r of proper design 

 and good construction.

The "triple crimp emasculators" (Pigs. 6, 7 and 8) are some- 

 what safer in controlling hemorrhage than the "single crimp" 

 instrument, as it crushes the cord in three directions. The author 

 has used a "triple crimp" instrument for several years with good 

 results. Many of the "triple crimp emasculators" now on the 

 market are imperfectly constructed and unsatisfactory in that 

 not enough space has been left between the male (upper) crush- 

 ing plate and the female (lower) plate — when the instrument is 

 closed — to receive the cord of a large stallion. Figs. 6, 7 and 8 

 illustrate two "triple crimp" emasculators both of which are 

 satisfactory. Fig. 8 is equipped with a self-adjusting auxilliary 

 attachment. The block attached to the male blade and longi- 

 tudinally serrated, is self-adjusting, by which means the com- 

 pressing surfaces maintain a parallel position when operated, 

 thereby preventing the cord and arteries from being mashed, cut 

 or torn at point nearest the hinge of the instrument. 



The spring device operating the auxiliary attachment permits
