PHYSIOLOGY OF THE OVIDUCT 423 



10. Wlien any portion of the ventral ligament is removed 

 it is not replaced but all remaining portions develop. 



11. The forward portion of the ventral ligament is necessary 

 for the reception of the yolk by the funnel. 



12. The muscle bundles which arise from the muscular cord 

 in the ventral ligament along the uterus are probably an im- 

 portant part of the normal apparatus which expels the egg.
