canal, termed the ductus epididymidis. The head of the 

 epididymis is thus composed of the lobules of the epi- 

 didymis and part of the coiled duct of the epididymis 

 embedded in areolar tissue. The body and tail of the 



epididymis are formed of 

 the continuation of the 

 same canal, coiled and con- 

 voluted upon itself to a 

 remarkable degree. 



The intricacy of its 

 flexuosities will be better 

 understood by simply stat- 

 ing that if the tube were 

 completely opened out it 

 would be found to measure 

 6 meters (twenty feet) or 

 more. At the lower end of 

 the tail of the epididymis 

 the duct of the epididymis becomes continuous with the 

 ductus deferens. 



Dissection. The dissector should endeavour to unravel a 

 part of the ductus epididymidis. The coils are held together by 

 areolar tissue and the dissection is very tedious. 



Penis. The penis was studied, to a certain extent, when 



the perineum was 

 dissected and its 

 two main consti- 

 tuent parts the

 attached to the corresponding side of the pubic arch. 

 Anteriorly the corpus cavernosum penis ends in a blunt 

 rounded extremity which is covered by the glans penis 

 (Figs. 82, 109).
