Fig. 10. Section showing a Mass of Vacuolated Plasmodium Invading the Decidua. Photo¬ 
graph. x 350 d. pi., plasmodium ; dec., decidua; n.z., necrotic zone of decidua. 
The mass of plasmodium shows a number of small vacuoles. It lies in a bay 
of the necrotic zone, and between the two are several large free, probably maternal, 
cells. The decidua is crowded with leucocytes. The decidual cells adjoining the necrotic 
zone show the early stages of degeneration ; further out they are more normal.

that figured in Fig. 7, Plate VII. Photograph. x 350 d. 
The nuclei are very irregular. The well-defined central cells belong to the innermost 
layer of the cyto-troplioblast.
