HUMAN ANATOMY. 



tened in front above, where attached to the penis and receiving the spermatic cords, 

 its general f orm i s pear-shaped and somewhat asymmetrical, since the left of the two 

 oval swellings produced by the enclosed testicles and separated by a shallow longi- 

 tudinal furnnv is lower than the right owing to the position of the corresponding 

 sexual gland. The scrotum varies, however, in form and appearance, even in the 

 same- individual, with the condition of the subcutaneous muscular tissue. When the 

 latter is contracted, as after the influence of cold, the scrotum is drawn up and com- 

 pact and its surface corrugated by numerous transversely curved folds ; when relaxed, 

 it becomes smooth, flaccid, and pendulous. 



Indications of its formation from two distinct parts are seen externally in the 

 longitudinal raf>lu\ which marks the line of fusion of the original halves and extends 

 longitudinally from the urethral surface of the penis over the scrotum onto the peri-

 aence of the union ,,f tin- srn.tal halvc-s is found in the sagittal partition (*/////// 

 i that is continued inward fn.m the raphe and effectually divides the scrotum 

 ghtand a 1, ft pouch. This septum, consisting of fibrous tissue rich in elastic 

 the prolongations of the dartos muscle, is attached above to the root of the 

 the perineum, blending with the sheath of the bulbo-cavernosus muscle. 

 the l.il.io-srrotal folds, which produce the scrotum or its homologiu-, tin- 

 ra, according to sex, are developed (page 2041) independently of the cov- 

 the spermatic cord and the testicle derived from the musculo-fascial walls of
