allantois could just be traced into the chorionic end of the cord. 

 Some injection was passed into the vessels of the cord, which filled 

 the principal vessels of the chorion ; but as the specimen had been 

 for some time in spirit before the injection was made, it did not 

 enter the vessels of the villi. Slender vessels, however, traversed 

 the non-villous spot opposite the os uteri, and some also were seen 

 subjacent to the amnion where it was in contact with the wall of the 

 tubular prolongation of the allantois situated in the left horn of the 

 chorion.
