CASTRATION OF TJiE HTALIJON

Tlie testiele.s vary iiuicli in size in different subjeels and are often of 

 iineqnal size in the same individnal. The epididymis (D, Fio'. 10) is an 

 elongated body extending along the upper border of the testes (A). It 

 consists of a body (D), a head or globus major (B), and a tail or globus 

 minor ( C ) . 



Vas Deferens — The vas deferens is a firm hard tube which, after leaving 

 the globus minor, ascends the back of the spermatic cord through the ex-

ternal abdominal ring, inguinal canal, and internal abdominal ring to the 

 abdominal cavity, where it enters the pelvis, jjassing to the antero-lateral 

 aspect of the bladder, where it is joined by the duct of the vesicula semi- 

 nales. This union of ducts takes place in the vicinity of the prostate gland. 



NATITKE's jrETIIOD OF CONTROLLING HEMORRHAGE 



It is well to always Ijear in mind that nature is a great factor in con- 

 trolling arterial hemorrhage. To understand exactly what ]mrt nature 

 plays when an artery is severed is knowledge which is never harmful to the 

 .surgeon, to say the least. The following occurs as soon as an artery is 

 severed: (1) Contraction of the mouth of the vessel (15, Fig. 11) ; (2) re- 

 traction of the vessel into its sheath (C, Fig. 11) ; (3) clot formation (D, 

 Fig. 11) ; (4) syncope. 



The function of the emasculator is to a.ssist nature in preventing pri- 

 mary or secondary hemorrhage. This is done by crushing the cord which 

 crimps or closes the spermatic artery, making the field more favorable for 

 clot formation. Never place an emasculator on a cord in any position ex- 

 cept at a right angle to the cord (Fig. 12). If the cord is severed at any 

 otlier angle (Fig. 13) fatal primary hemorrhage is liable to occur.
