The bat is dun with wrinkled wings

The Bat is dun, with wrinkled Wings -
Like fallow Article -
And not a song pervade his Lips -
Or none perceptible.

His small Umbrella quaintly halved
Describing in the Air
An Arc alike inscrutable
Elate Philosopher.

Deputed from what Firmament -
Of what Astute Abode -
Empowered with what malignity
Auspiciously withheld -

To his adroit Creator
Ascribe no less the praise -
Beneficent, believe me,
His eccentricities -
