Integuments of the Penis. 



The glans penis, the structure of which has been already 

 described, is covered by a continuation of the skin which 

 appears altered in its texture so as to resemble in some respects 

 the skin of the lips, and in like manner is covered by a delicate 

 production of cuticle. 



Around the corona of the glans, especially on its upper part, 

 there are whitish tubercles, glandula Tysonii, which are of 

 different sizes in different persons, but always very small. The 

 skin adheres firmly to the whole extent of the corona of the 

 glans, and is very delicate in its structure, as it continues from 

 the glans upon the body of the penis ; but it gradually changes 

 so as to assume the appearance and structure of a common 

 skin, and continues in this state over the penis. The adhesion 

 of the skin to the ligamentous coat of the corpora cavernosa 

 also becomes more loose, owing to the quantity and texture of 

 the cellular substance which connects them. The skin, thus 

 connected to the penis, has commonly more length than that 

 organ, even in its extended state. In consequence of this greater 

 length, and of its adhering firmly around the corona glandis, 

 it necessarily forms a circular fold or plait, which varies in size 

 according to the length of the skin. This fold is generally 

 situated at the commencement of the firm attachment of the 

 skin to the body of the penis, or around the glans ; but it may 

 be formed any where upon the body of the penis by artificial 

 management. 



This duplicature, or fold of the skin, when it takes place so 

 as to cover the glans, is called the Prepuce; and the skin,
