hawk-moth with an enormously long proboscis, and he does this on account of
the discovery there of an orchid with a nectary from ten to fourteen inches
in length. See _Quarterly Journal of Science_, October 1867, and "Natural

[14] "Pangenesis" is the name of the new theory proposed by Mr. Darwin, in
order to account for various obscure physiological facts, such, _e.g._, as
the occasional reproduction, by individuals, of parts which they have lost;
the appearance in offspring of parental, and sometimes of remote ancestral,
characters, &c. It accounts for these phenomena by supposing that every
creature possesses countless indefinitely-minute organic atoms, termed
"gemmules," which atoms are supposed to be generated in every part of every
organ, to be in constant circulation about the body, and to have the power
of reproduction. Moreover, atoms from every part are supposed to be stored
in the generative products.
