No radiant pearl which crested Fortune wears,
No gem that twinkling hangs from Beauty's ears,
Not the bright stars which Night's blue arch adorn,
Nor rising suns that gild the vernal morn,
Shine with such lustre as the tear that flows
Down Virtue's manly cheek for others' woes.

The Botanic Garden (1791), Part ii, Canto iii, line 459.
