peculiar odor, and is beset with thinly scattered, crisp hairs, the roots of which 

 are seen through the skin. 



The Dartos Tunic (tunica dartos} is a thin layer of non-striped muscular fibers, 

 continuous, around the base of the scrotum, with the two layers of the superficial 

 fascia of the groin and the perineum; it sends inward a septum, which divides 

 the scrota! pouch into two cavities for the testes, and extends between the raphe 

 and the under surface of the penis, as far as its root.

FIG. 1 144. The scrotum. The penis has been turned upward, and the-anterior wall of the scrotum has been removed. 

 On the right side, the spermatic cord, the infundibuliform fascia, and the Cremaster muscle are displayed; on the left 

 side, the infundibuliform fascia has been divided by a longitudinal incision passing along the front of the cord and the 

 testicle, and a portion of the parietal layer of the tunica vaginalis has been removed to display the testicle and p, portion 

 of the head of the epididymis, which are covered by the visceral layer of the tunica vaginalis. (Toldt.) 



The dartos tunic is closely united to the skin externally, but connected with 

 the subjacent parts by delicate areolar tissue, upon which it glides with the 

 greatest facility. 



The Intercrural Fascia (intercolumnar or external spermatic fascia) is a thin 

 membrane, prolonged downward around the surface of the cord and testis .(see 

 page 411). It is separated from the dartos tunic by loose areolar tissue. 



The Cremaster consists of scattered bundles of muscular fibers connected 

 together into a continuous covering by intermediate areplar. tissue (see page 414).
