implanted, resembled in all respects the ordinary skin of the 

 surface of the body. 



A few hairs appeared to arise from the general surface of 

 the tunica vaginalis. 



In the substance of the club-shaped projections, but par- 

 ticularly in the larger of the two, where it adhered to the 

 mass of the testis, there were irregular masses of soft cartilage, 

 presenting all the ordinary characters of the corpuscles of 

 that texture, and a few vascular canals. 



In some places this cartilage had been converted into bone, 

 in which were visible irregular Haversian canals and numerous 

 corpuscles and canaliculi. 



One portion of bone resembling a sand-glass measured 

 half-an-inch in length.
