eral .years with good results. JMauy of the triple-crimp emasculators now 

 on the market are imperfeetl.y constructed and unsatisfactory in that not^ 

 enough space has been left between the male (upper) crushing plate and,: 

 the female (lower) plate — when the instrument is closed — to accommodate 

 the cord of a large stallion. i 



Figs. 6 and 7 illustrate the Betz triple-crimp emasculator. This instru- 

 ment is properly designed and well constructed. Of the several different 

 makes of triple-crimp instruments now on the American market, the Betz 

 emasculator is absolutely the oulv one which the author can conscien-

tiously indorse and recommend. All the others are defective in some im- 

 portant particular. 



1'he latest improved and possibly the instrument by which the most 

 perfect spermatic cord hemostasis is accomplished — regardless of age and 

 size of the animal — is Dunn 's safety emasculator ( Fig. 8 ) . 



The advantage which this instrument possesses over all others consists 

 of a beveled extension to the crushing (female) jaw. By means of this 

 beveled-extension feature the spermatic cord is drawn into the space be- 

 tween it and the upper blade and gradually compressed Ijefore the crush- 

 ing and cutting is done. 



This simply means that when the instrument is closed on the cord, the 

 stump of tlie cord itself is aifected by all degrees of crushing, from barely 

 being touched at the top of the beveled portion of the lower blade to being 

 completely severed — by crusliing and cutting — at the lower part of the 

 upper blade. 



Handled in this manner the stump of the cord is fairly well sealed so 

 that primary hemorrhage from it will be slight. The Dunn Safety Emas- 

 culator must be used in order to be properly appreciated.
