And make the moon-beam brighter where they flow.

Involved in sea-wrack, here you find a race,

Which science, doubting, knows not where to place;

On shell or stone is dropp'd the embryo-seed,

And quickly vegetates a vital breed[59].

While thus with pleasing wonder you inspect

Treasures the vulgar in their scorn reject,

See as they float along th' entangled weeds

Slowly approach, upborne on bladdery beads;
