 evident, but the more frequent condition of retained cotyle- 

 dons, after the falling away of the chorion, is not readily 

 diagnosable clinically. The genital passages do not admit

 nosis must then rest upon the presence of the metritic dis- 

 charge, usually dark red, sanious, mixed with necrotic pla- 

 cental fragments, and fetid. The diagnosis is clear enough 

 as to metritis, but not as clear, except for the placental frag- 

 ments, as to retained placenta. The differentiation, however, 

 between metritis with or without placental retention is not 

 profoundly important. They possess essentially the same 

 dangers and call for analogous handling.
