Some in huge masses, some that you may bring
In the small compass of a lady’s ring;
Figured by hand divine - there’s not a gem
Wrought by man’s art to be compared to them;
Soft, brilliant, tender, through the wave they glow,
And make the moonbeam 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.
