12 Jackson's Dissection of 



with intermediate, oblique lines, somewhat like the arbor vitae 

 in the human cervix uteri. Muscular coat became more and 

 more thick towards opening into vagina, where at last it 

 measured from two to three lines. 



Penis twenty inches in length, and for the most part about 

 as large as the fore-finger, though near the pubes much larger. 

 Towards the free extremity it gradually diminished in size, 

 tapering almost to a point, and in a very remarkable manner ; 

 the last seven lines were bent to a right angle with the 

 body of the organ, and somewhat twisted, having the dense 

 feel of cartilage, and measuring at the very extremity but two 

 lines in diameter. The urethra terminated just at or beneath 

 the angle formed by this last portion, and was still further 

 concealed by a firni, sharp point, two lines in length, which 

 projected forwards from one side of its orifice. The lining 

 membrane of this canal was dense, and about one-half a line 

 thick : some spongy tissue externally about midway ; no 

 muscular fibres seen. Corpora cavernosa formed by an abun- 

 dant, coarse, cellulo-fibrous network, without a septum : the 

 investing fibrous membrane extremely thick and dense, meas- 

 uring from one to one and a half lines. Besides some smaller 

 muscles, a short, thick pair arose from the pubes to be inserted 

 into the penis near its origin, and a long, slender, and very 

 beautiful pair ran nearly the whole length of the organ, along 

 its under surface, connected with the sphincter ani at one ex- 

 tremity, and lost in the integuments at the other. The 

 prepuce was five inches long, and formed a large, thick mass 

 of flesh, consisting of cellular substance intermixed with 

 some r^uscular fibres ; fraenum distinct. 



Vasa Deferentia within the pelvis at first tortuous, but for 

 the last four or five inches straight ; rather more than one 

 line in diameter at fii'st, the canal being a mere pin hole. 

 Towards their termination the diameter increases to three 

 lines, and being cut open, the cavity measures about three 

 lines transversely ; inner surface smooth and polished, show- 

 ing the openings of numerous minute follicles. Terminated 

 at last in the urethra, on each side of the verumontanum. 

 No note made of the testicles.
