X 10. A short segment of the upper end of the uterine horn was included in the reconstruction, lower end of the figure. The position of three of the morula masses, 12-cell to 16-cell stages, in the terminal part of the oviduct is to be noted, a further one is located in the upper part of the uterine horn. These are shown as if seen through a transparent wall. \ fifth morula, situated in the uterine horn about cm. from the entrance of the oviduct, is not included in the figure. tion as seen in figure 17, showing six of the eight cells, each cut in the plane of its nucleus. In both of these figures (figs. 17 and 19) the morula masses, as seen in the sections drawn, present a quite regular oval outUne. In succeeding sections, in which the mucosal fold and the wall of the oviduct approximate, the cross diameter of each of the four morula masses becomes greatly reduced, they appearing in the final sections of the series in which they are included as narrow, non-nucleated bands of Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Huber, Gotthelf Carl, 1865-.
