sketch. On the cut. surfaces a large corpus luteum is seen occupying the 
lower end of the ovary close up to the hilum. Fully half the section is 
constituted by apparently normal ovarian tissue. The marginal portion, 
however, more deeply shaded in the figure, consists of blood-infiltrated 
stroma and blood clot. Within this portion of the gland, in a small cavity 
of irregularly oval shape, lies the chorionic vesicle separated from the corpus 
luteum by a considerable zone of blood clot. The knife has cut both the

corpus luteum and vesicle unequally, the greater portion of each remaining 
in the lateral segment to the left in the figure. A complete series of 
sections through the whole ovary being, in the circumstances, impossible, 
a slice of about 3 mm. thick was taken from the outer portion, including 
the greater part of the corpus luteum and a complete section of the 
chorionic vesicle. This block of tissue was converted into a complete 
series of sections 8 microns thick, and stained in various ways. A second 
portion of tissue was then taken out from above the corpus luteum to 
complete the section of that structure in this, plane, and to establish its
