A. The 17-somite embryo H951. X 16.6. Embryo H951 (fig. 1, A) was obtained from Drs. E. L. Whitney and J. T. Rocks, of Walla Walla, Washington. “The uterus was removed for fibrosis on the 13th day after the day on which menstruation was expected to begin,” opened and fixed in ‘4%’ formalin. No further clinical information could be obtained. B. The 22—somite embryo H1093. X 10. 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. C. The 23-somite embryo H984. X 16.6. Embryo H984 (fig. 1, C) was donated to the collection by Drs. E. W. Rawson and B. H. Foreman of Tacoma, Washington.
