In the mean time the vesicle loses its original round shape, becoming stretched, and assuming the most various forms (fig. 369.). At last the vesicle bursts at some place, and allows the spermatozoa to come forth. ( Fig. 370.) The spermatozoa having thus become free, group themselves together into regular bun- dles, still enclosed by the mother cell of the vesicle of developement. This at least seems to be the case invariably wherever the cyst persists long enough. It, however, some- Fig. 369.
