These glands do not lie in the body-cavity, but are embedded 

 in the muscular wall of the body in the spots where they 

 severally open to the exterior. No trace of them can there- 

 fore, as Beddard says, be seen in an ordinary dissection of the 

 worm. I cannot say what their function may be.
