The embryo was sectioned into 323 sections at 10 µ.
- Embryo H1093 (fig. 1, B) was obtained by Dr. Garrette Van Sweringen and Dr. W. W. Duemling, of Fort Wayne, Indiana. The clinical record gives the following points: “The October period began on the 6th, 1924; next period from 10th to 14th or 15th. The expected period on December 10th did not appear. Flow supposed to be menstruation appeared on December 22nd, but bloody discharge continued until 31st. Contraceptive measures were employed until after November period. Symptoms of ectopic pregnancy were observed on January 4, 1925, and operation was performed on the same day.” In cutting open the hematoma, the head of the embryo was severed from the trunk just caudal to the otocyst. Although no loss of tissue is apparently involved, yet the difference in the plane of sections of the two portions of the embryo makes it materially difficult to follow the series in the region of rhombomere VI. The specimen was fixed in neutral formalin, double embedded, cut transversely, and stained with iron hematoxylin. Histological differentiation is fair, but there is much shrinkage. Cells with coarse granules evidently representing necrobiosis are found abundant in the neural crest as well as the medullary tube. A wax model of the nervous system in front of the otocyst was made from serial photomicrographs at the magnification of 150 times.[1]
