Publisher's Synopsis
Excerpt from The Spermatogenesis of Hydra: A Dissertation Submitted to the Faculty of the Ogden Graduate School of Science in Candidacy for the Degree of Doctor of Philosophy (Department of Botany)
In 1872 kleinenberg (47) published his volume on Hydra. Regarding the Spermatogenesis he says that the formation of the spermary begins by the rapid growth of the interstitial cells over a limited circular area. These divide rapidly a number of times, then become amoeboid. Ultimately they pack closely together and elongate. The nucleus then disintegrates while the cell substance becomes granular. There then appear in the cells, one to four strongly refractive oval bodies, whether formed from the disinte grated nucleus or not he does not know. These refractive bodies become the nuclei of smaller cells from which the sperm form by the growth of the tail from one end.
