hatching approaches
the chick is liable to break this air-bag with its beak, and
thence begin to breathe and to chirp; at this time the edges
of the enlarged air-bag extend so as to cover internally one
hemisphere of the egg; and as one half of the external shell
is thus moist, and the other half dry, as soon as the mother
hearing the chick chirp, or the chick itself wanting
respirable air, strikes the egg, about its equatorial line,
it breaks into two hemispheres, and liberates the prisoner.]

[Footnote: _And whisper to the song_, l. 356. A curious
circumstance is mentioned by Kircherus de Musurgia, in his
Chapter de Lusciniis. "That the young nightingales, that are
hatched under other birds, never sing till they are
instructed by the company of other nightingales." And
Johnston affirms, that the nightingales that visit Scotland,
have not the same harmony as those of Italy, (Pennant's
Zoology, octavo, p. 255), which would lead us to suspect,
that the singing of birds, like human music, is an artificial
language rather than a natural expression of passion.]

"The Lion-King forgets his savage pride,
And courts with playful paws his tawny bride;
The listening Tiger hears with kindling flame
The love-lorn night-call of his brinded dame. 360
Despotic LOVE dissolves the bestial war,
Bends their proud necks, and joins them to his car;
Shakes o'er the obedient pairs his silken thong,
And goads the humble, or restrains the strong.--
Slow roll the silver wheels,--in beauty's pride
Celestial PSYCHE blushing by his side.--
The lordly Bull behind and warrior Horse
With voice of thunder shake the echoing course,
Chain'd to the car with herds domestic move,
And swell the triumph of despotic LOVE. 370

"Pleased as they pass along the breezy shore
In twinkling shoals the scaly realms adore,
Move on quick fin with undulating train,
Or lift their slimy foreheads from the main.
High o'er their heads on pinions broad display'd
The feather'd nations shed a floating shade;
Pair after pair enamour'd shoot along,
And trill in air the gay impassion'd song.
With busy hum in playful swarms around
Emerging insects leave the peopled ground, 380
Rise in dark cloud
