In consequence, the number of segments has been diminished or reduced to half the normal number. In exactly the same way division with reduction occurs in the egg of Ascaris megalocephala during the process of ripening. The sperm-mother-cell corresponds to the unripe egg, or egg- mother-cell. Here also eight nuclear segments, arranged in two bundles, develop in the germinal vesicle (Fig. 127 L). After the nuclear membraiie has been dissolved, they arrange themselves in the equator of the first direction spindle, which rises up to the surface of the yolk (Fig. 127 II.), and in the manner already 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 Hertwig, Oscar, 1849-1922; Campbell, M. , tr; Campbell, Henry Johnstone, 1859- ed.
