V, villus ; Tr., mass of Langhans’ layer cells ; pi., plasmodium ; bl.c., blood clot ; hg., 
haemorrhage; str., stroma of ovary ; bl.v., blood-vessel in stroma. 
A portion of the stroma has been selected in which runs a large vessel; this, when 
traced through the sections, was found to open out into the gestation sac. The stroma 
adjoining the cavity is necrotic. Masses of plasmodium are seen attached to it, both 
on the right above the haemorrhage, and to the left above the blood-vessel.
