I sat upon a promontory,
And heard a mermaid, on a dolphin's back,
Uttering such dulcet and harmonious breath,
That the rude sea grew civil at her song;
And certain stars shot madly from their spheres,
To hear the sea-maid's music.
Omission to do what is necessary Seals a commission to a blank of danger; And danger, like an ague, subtly taints Even then when we sit idly in the sun.
