and more recently by Findley, 1 while Leopold has described the 

 appearance of the fatty degeneration as a result rather than a cause 

 of haemorrhage. 



After the extravasation of blood, the corpuscles tend to become 

 aggregated in lacunae which lie beneath the superficial epithelium. 

 These lacunae are the sub-epithelial homiatornata of Gebhard,- 

 according to whom the epithelium becomes lifted almost bodily from 

 its bed, the space between it and the stroma being filled with blood. 

 Gebhard concludes that the blood eventually reaches the uterine

 exit is provided by certain of the cells being carried bodily a\\;iy. 

 Gebhard also believes that bleeding may take place into the lumina 

 of the glands. Christ 3 states that when the menstrual flow is very 

 profuse there is a considerable loss of surface epithelium, but that in 

 other cases the removal of epithelium is slight. This author has 

 also described bleeding into the glands. (Fig. 10.)
