 uterus and the lower end of the tube and its derivatives pene-

 direction from the peritoneal side. 



The character of the embryonal structures and their relation 

 to the surrounding tissue are more clearly shown on Fig. 2. b is

the fallopian tube, a is the embryo, which is surrounded by 

 placental structures c and d and other similar not especially 

 designated structures. In the periphery of these structures are 

 found extensive hemorrhages into the connective tissues and these 

 are in turn surrounded by strands of connective tissue and by 

 blood vessels. The entire region between the tubes and the 

 outer hemorrhagic zone is filled out by embryonal placenta. 



The embryo proper corresponds to a developing guinea pig at 

 a stage directly following the formation of the germ layers.
