The enclosed cells of developement are equally as capable of producing these forma- tions as the free ones, as one may icadily convince oneself by observation through the microscope (Jig. 33].). On the destruction Fig. A Mother Cell from the Coch, iritli tin-re Spermatozoa still enclosed in their Cells of Developement. of the membrane of the cells of develope- ment, the spermatozoa get into the in- terior of the cysts (fig- 332.), where they lie together often in a great number, but never * Lehrbuch tier Physiol. 3d edit. § 18.

Finally, this cyst also gets dissolved, without, however, Fig. 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 Todd, Robert Bentley, 1809-1860.
