muscle and carry with them and retain fibres derived from its lower part. It occasionally happens 

 that the loops of the Cremaster surround the cord, some lying behind as well as in front. It is 

 probable that under these circumstances the testis, in its descent, passed through instead of 

 beneath the fibres of the Internal oblique. 



In the descent of an oblique inguinal hernia, which takes the same course as the spermatic 

 cord, the Cremaster muscle forms one of its coverings. This muscle becomes largely developed 

 in cases of hydrocele and large old scrotal hernia. The Cremaster muscle is found only in the

 round ligament which correspond to this muscle, and in cases of oblique inguinal hernia in 

 the female a considerable amount of muscle tissue may be found covering the sac.
