Plate 1

1 “Gar.” The specimen as received. The ovum is seen as a dark projection at the upper end of the uterine cavity. x 0.5

2 “ Gar.” Block of tissue containing the ovum removed for sectioning. This photograph should be turned 90° to the right, to correspond with its position in fig. 1. x 2.25

3 “Gar.” Slide 51, sec. 3. Through the middle of the ovum. A small part of the muscularis is seen at the lower edge of the photograph; projecting into it are some of the glands in the pars basalis of the stratum spongiosum of the endometrium. Passing towards the surface are seen the pars functionalis of the stratum spongiosum and then the stratum compactum. The embryo is seen in the deepest part of the chorionic sac. x 9

4 “ Mal.” Section through the middle of the ovum. The chorionic sac is seen to be collapsed. The endometrium is so much thicker than in “Gar” that no muscularis is seen in this photograph. The stratum compactum and dilated glands of the stratum spongiosum are well seen. The embryo is at the middle of the lower border of the sac. x 9

5 “Dible-West” ovum. The ovum is seen as a small elliptical cavity just within the endometrium; part of the muscularis is seen below. Above this there is one large dilated gland. x 9
