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;
