Are here, and likenesses of many a shell
Tossed ashore by restless waves,
Or in the diver’s grasp fetched up from caves
Where sea-nymphs might be proud to dwell: 15
But whose rash hand (again I ask) could dare,
’Mid casual tokens and promiscuous shows,
To circumscribe this Shape in fixed repose;
Could imitate for indolent survey,
Perhaps for touch profane, 20
Plumes that might catch, but cannot keep, a stain;
