Another, and much more rare consequence of an opening of the 

 urethra into the sheath, is the gradual formation of one or more fis- 

 tulous tracks along the penis, terminating behind the corona glandis, 

 and causing a good deal of thickening and induration of the tissues 

 along their course. 



Other pathological and physiological relations will doubtless be 

 deduced from this anatomical structure, when attention shall be more 

 extensively directed to it. 



The accompanying drawing, PI. V., representing the dissection of 

 the sheath of the penis, was made by my pupil, Mr. Moreau Morris.
