accessori(v). That these placentae really can replace the coty- 

 ledons, a case described by St. Cyr and Violet indicates : 



A primipara suffering with prolapsus uteri had nearly all 

 the cotyledons destroyed, and in order to prevent hemorrhage 

 and infection each cotyledon was ligated and removed. Next 

 reposition of the prolapsed uterus was effected, the animal 

 recovering shortly. One year later the cow gave birth to a 

 healthy calf without assistance.

((, Mucosa ; b, sub-niucosa ; e, glands. 



Our literature enumerates several cases where pregnancy 

 again occurred after forcible removal of the cotyledons. On 

 the surface of the cotyledons union with the chorion takes 

 place; into the depressions of the placentae maternae the villi 

 of the placentae fcetalis are inserted. The uterine glands 

 (glandules uterince), somewhat wave-like in the non-pregnant 

 uterus, enlarge during pregnancy by throwing out bud-like 

 processes; the excretory duct is of a corkscrew shape.
