 crural region and perineum, and sends a septum inwards 

 which divides the scrotal bag into two cavities, thus sep- 

 arating the testes. The dartos is connected with the 

 subjacent parts by delicate areolar tissue, allowing of the 

 free movement of the scrotal structures over the testes, 

 and owing to the corrugating power it has over the scro- 

 tal tissues, it is difficult to approximate the edges of in- 

 cisions when made in its structure. A fibro-ceUular coat
