These in the pericarp erewhile arrive,
Rush to each other, and embrace alive.
--Form'd by new powers progressive parts succeed,
Join in one whole, and swell into a seed.

[Footnote: _With appetencies just_, l. 271. As in the
productions by chemical affinity one set of particles must
possess the power of attraction, and the other the aptitude
to be attracted, as when iron approaches a magnet; so when
animal particles unite, whether in digestion or reproduction,
some of them must possess an appetite to unite, and others a
propensity to be united. The former of these are secreted by
the anthers from the vegetable blood, and the latter by the
styles or pericarp; see the Additional Note VIII. on
Reproduction.]

"So in fond swarms the living Anthers shine
Of bright Vallisner on the wavy Rhine; 280
Break from their stems, and on the liquid glass
Surround the admiring stigmas as they pass;
The love-sick Beauties lift their essenced brows,
Sigh to the Cyprian queen their secret vows,

under water, and as soon as their farina or dust is mature,
they detach themselves from the plant, rise to the surface
and continue to flourish, and are wafted by the air or borne
by the current to the female flowers. In this they resemble
those tribes of insects, where the males at certain seasons
acquire wings, but not the females, as ants, coccus,
lampyris, phalaena, brumata, lichanella; Botanic Garden, Vol.
II. Note on Vallisneria.]

"Hence the male Ants their gauzy wings unfold,
And young Lampyris waves his plumes of gold;
The Glow-Worm sparkles with impassion'd light
On each green bank, and charms the eye of night; 290
While new desires the painted Snail perplex,
And twofold love unites the double sex.

some seasons so luminous, that M. Merian says, that by
putting two of them under a glass, she was able to draw her
figures of them by night. Whether the light of thi
