THE ANATOMY OP THE HORSE. 



yellowish body — the corpus luteum. In the early stage of a corpus 

 luteum the cells of the membrana granulosa proliferate, while capil- 

 laries extend into it from the wall of the follicle. Later on the blood- 

 clot in the centre becomes decolorised, and the granulosa cells become 

 fatty ; and finally the corpus luteum shrinks and disappears. 



The Pabovabium, or the Organ op Rosenmullbr. This is a minute 

 body situated in the broad ligament, between the ovary and the 

 Fallopian tube. It consists of a number of short convoluted tubules 

 opening into a longitudinal tube, the latter representing the canal of 

 Gcertner in the cow. The parovarium is the homologue of the epididymis 

 of the male. 



The Fallopian Tubes, or Oviducts. The Fallopian tube is the duct 

 for the conveyance of the ova from the ovary to the uterus. In its

course between these two organs the tube passes in a flexuous manner 

 at the anterior border of the broad ligament. The ovarian extremity 

 of the tube opens on the surface of an expansion whose rim is cut into 

 a few short fringe -like processes — the fimhrim. Inwardly the rim 

 of this expansion is fixed to the surface of the ovary near the hilus. 

 The upper surface of the expansion is covered by a mucous membrane 

 with delicate rugae that converge from its rim to its centre, where it 

 shows the orifice of the tube — the ostium ahdominale. The under surface
