Darwin's keen analogy of the fertilization of plants by pollen renders development from without conceivable, but as there are no insects to convey gemmules to their destination, each kind of gemmule would have to be exceedingly numerous and easily attracted from amongst an inconceivable number of other gemmules.    From Wordnik.com.  [Are the Effects of Use and Disuse Inherited? An Examination of the View Held by Spencer and Darwin] Reference

The "gemmule" of a Halimeda contained several articulations united, ready to burst their envelope, and become attached to some basis.    From Wordnik.com.  [More Letters of Charles Darwin — Volume 1] Reference

For our "plumule" we have also "gemmule", and French has both of these too.    From Wordnik.com.  [languagehat.com: PLUMULE.] Reference

We can easily conceive a being so small, that a gemmule would be to it as large as St. Paul's would be to us.    From Wordnik.com.  [On the Genesis of Species] Reference

In this regard, he likened Darwin's gemmule theory to Newton's corpuscular theory of light and the molecular theory of matter.    From Wordnik.com.  [Chauncey Wright] Reference

What wonder then that such an excessively complex body should divide and multiply; and what parity is there between such a body and a gemmule?.    From Wordnik.com.  [On the Genesis of Species] Reference

It is remarkable that Mr. Darwin brings forward in support of gemmule fission, the observation that "Thuret has seen the zoospore of an alga divide itself, and both halves germinate.".    From Wordnik.com.  [On the Genesis of Species] Reference

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.    From Wordnik.com.  [On the Genesis of Species] Reference

Moreover, the one mystery in the case of the "physiological unit" explains all, while with regard to the gemmule, as we have seen, it has to be supplemented by other powers and tendencies, each distinct, and each in itself inexplicable and profoundly mysterious.    From Wordnik.com.  [On the Genesis of Species] Reference

It requires no greater effort on the part of nature to produce the pine, the oak, the beech, the hickory -- all of which we see springing directly from primordial germs to-day -- than it did to produce the lowest vegetal organism, from an invisible, indestructible "vital unit," or Darwinian gemmule, thousands of years ago.    From Wordnik.com.  [Life: Its True Genesis] Reference

Each gemmule, according to Mr. Darwin, is really the seat of powers, elective affinities, and special tendencies as marked and mysterious as those possessed by the physiological unit of Mr. Spencer, with the single exception that the former has no tendency to build up the whole living, complex organism of which it forms a part.    From Wordnik.com.  [On the Genesis of Species] Reference

Some may think this an important distinction, but it can hardly be so, for Mr. Darwin considers that his gemmule has the innate power and tendency to build up and transform itself into the whole living, complex cell of which it forms a part; and the one tendency is, in principle, fully as difficult to understand, fully as mysterious, as is the other.    From Wordnik.com.  [On the Genesis of Species] Reference

I believe in zoophytes universally the gemmule produces a single polypus, which afterwards or at the same time grows with its cell or single articulation.    From Wordnik.com.  [More Letters of Charles Darwin — Volume 1] Reference

Every gemmule may multiply itself by a process of scission into any number of equivalent gemmules. ".    From Wordnik.com.  [On the Genesis of Species] Reference

If we refuse it to the individuals which embody the species, we must admit it as regards their component parts -- nay, even if we accept the hypothesis of pangenesis, we are nevertheless compelled to attribute to each gemmule that peculiar power of reproducing its own nature (its own.    From Wordnik.com.  [On the Genesis of Species] Reference

From a single deep impression on a parent, affecting both himself as a whole, and gravely confusing the memories of the cells to be reproduced, or his memories in respect of those cells -- according as one adopts Pangenesis and supposes a memory to "run" each gemmule, or as one supposes one memory to "run" the whole impregnate ovum -- a compromise between these two views being nevertheless perhaps possible, inasmuch as the combined memories of all the cells may possibly BE the memory which "runs" the impregnate ovum, just as we.    From Wordnik.com.  [Life and Habit] Reference
