[Anemone. l. 318. Many males, many females. Pliny says this flower never opens its petals but when the wind blows; whence its name: it has properly no calix, but two or three sets of petals, three in each set, which are folded over the stamens and pistil in a singular and beautiful manner, and differs also from ranunculus in not having a melliferous pore on the claw of each petal. ]
[The Swallow. l. 322. There is a wonderful conformity between the vegetation of some plants, and the arrival of certain birds of passage. Linneus observes that the wood anemone blows in Sweden on the arrival of the swallow; and the marsh mary-gold, Caltha, when the cuckoo sings. Near the same coincidence was observed in England by Stillingfleet. The word Coccux in Greek signifies both a young fig and a cuckoo, which is supposed to have arisen from the coincidence of their appearance in Greece. Perhaps a similar coincidence of appearance in some parts of Asia gave occasion to the story of the loves of the rose and nightingale, so much celebrated by the eastern poets. See Dianthus. The times however of the appearance of vegetables in the spring seem occasionally to be influenced by their acquired habits, as well as by their sensibility to heat: for the roots of potatoes, onions, &c. will germinate with much less heat in the spring than in the autumn; as is easily observable where these roots are stored for use; and hence malt is best made in the spring. 2d. The grains and roots brought from more southern latitudes germinate here sooner than those which are brought from more northern ones, owing to their acquired habits. Fordyce on Agriculture. 3d. It was observed by one of the scholars of Linneus, that the apple-trees sent from hence to New England blossomed for a few years too early for that climate, and bore no fruit; but afterwards learnt to accommodate themselves to their new situation. (Kalm's Travels.) 4th. The parts of animals become more sensible to heat after having been previously exposed to cold, as our hands glow on coming into the house after having held snow in them; this seems to happen to vegetables; for vines in grape-houses, which have been exposed to the winter's cold, will become forwarder and more vigorous than those which have been kept during the winter in the house. (Kenedy on Gardening.) This accounts for the very rapid vegetation in the northern latitudes after the solution of the snows.
The increase of the irritability of plants in respect to heat, after having been previously exposed to cold, is further illustrated by an experiment of Dr. Walker's. He cut apertures into a birch-tree at different heights; and on the 26th of March some of these apertures bled, or oozed with the sap-juice, when the thermometer was at 39; which same apertures did not bleed on the 13th of March, when the thermometer was at 44. The reason of this I apprehend was, because on the night of the 25th the thermometer was as low as 34; whereas on the night of the 12th it was at 41; though the ingenious author ascribes it to another cause.

"Breathe, gentle AIR! from cherub-lips impart
Thy balmy influence to my anguish'd heart;
325 Thou, whose soft voice calls forth the tender blooms,
Whose pencil paints them, and whose breath perfumes;
O chase the Fiend of Frost, with leaden mace
Who seals in death-like sleep my hapless race;
Melt his hard heart, release his iron hand,
330 And give my ivory petals to expand.
So may each bud, that decks the brow of spring,
Shed all its incense on thy wafting wing!"—
To her fond prayer propitious Zephyr yields,
Sweeps on his sliding shell through azure fields,
335 O'er her fair mansion waves his whispering wand,
And gives her ivory petals to expand;
Gives with new life her filial train to rise,
And hail with kindling smiles the genial skies.
So shines the Nymph in beauty's blushing pride,
340 When Zephyr wafts her deep calash aside;
Tears with rude kiss her bosom's gauzy veil,
And flings the fluttering kerchief to the gale.
So bright, the folding canopy undrawn,
Glides the gilt Landau o'er the velvet lawn,
345 Of beaux and belles displays the glittering throng;
And soft airs fan them, as they roll along.
Where frowning Snowden bends his dizzy brow
O'er Conway, listening to the surge below;
Retiring LICHEN climbs the topmost stone,
350 And 'mid the airy ocean dwells alone.—
Bright shine the stars unnumber'd o'er her head,
And the cold moon-beam gilds her flinty bed;
While round the rifted rocks hoarse whirlwinds breathe,
And dark with thunder sail the clouds beneath.—
355 The steepy path her plighted swain pursues,
And tracks her light step o'er th' imprinted dews,
Delighted Hymen gives his torch to blaze,
Winds round the craggs, and lights the mazy ways;
[Lichen. l. 349. Calcareum. Liver-wort. Clandestine Marriage. This plant is the first that vegetates on naked rocks, covering them with a kind of tapestry, and draws its nourishment perhaps chiefly from the air; after it perishes, earth enough is left for other mosses to root themselves; and after some ages a soil is produced sufficient for the growth of more succulent and large vegetables. In this manner perhaps the whole earth has been gradually covered with vegetation, after it was raised out of the primeval ocean by subterraneous fires.]
Sheds o'er their secret vows his influence chaste,
360 And decks with roses the admiring waste.
High in the front of heaven when Sirius glares,
And o'er Britannia shakes his fiery hairs;
When no soft shower descends, no dew distills,
Her wave-worn channels dry, and mute her rills;
365 When droops the sickening herb, the blossom fades,
And parch'd earth gapes beneath the withering glades.
—With languid step fair DYPSACA retreats;
"Fall gentle dews!" the fainting nymph repeats;
Seeks the low dell, and in the sultry shade
370 Invokes in vain the Naiads to her aid.—
