By means of the germinative affinity, every gemmule (except in cases of anomalies or monstrosities) can be developed only in cells homologous with the mother-cells of the cell from which they originated.

In other words, the gemmules from any cell can only be developed in unison with the cell preceding it in due order of succession, and whilst in a nascent state.
"7.

Of each kind of gernmule a great number perishes; a great number remains in a dormant state through many generations in the bodies of descendants; the remainder germinate and reproduce the mother-cell.
"8.

Every gemmule may multiply itself by a process of scission into any number of equivalent gemmules." Mr.Darwin has published a short notice in reply to Professor Delpino, in _Scientific Opinion_ of October 20, 1869, p.426.In this reply he admits the justice of Professor Delpino's attack, but objects to the alleged necessity of the first subordinate hypothesis, namely, that the emission of gemmules takes place in all states of the cell.

But if this is not the case, then a great part of the utility and distinction of pangenesis is destroyed, or as Mr.Lewes justly says,[225] "If gemmules produce whole cells, we have the very power which was pronounced mysterious in larger organisms." {215} Mr.Darwin also does not see the force of the objection to the power of self-division which must be asserted of the gemmules themselves if Pangenesis be true.
