had an influence in throwing doubt upon this subject, but from a mere consideration of the 

 literature it is clear that neither Giard's position nor the doubt diffused from it are justified. 

 From my own observations recorded in chapter 4 of this book, I am forced to the conclusion 

 that Delage's account of the life-history of Sacadina is in its main outlines perfectly correct, 

 the two fundamental postulates of Delage's account, (1) that Sacadina passes through an entirely 

 endoparasitic stage, and (2) that it enters the body of the host at some point other than that 

 at which it is finally affixed in the adult state, being confirmed in detail.
