See how he frames his eyes, poises each limb,
Puts the whole body into proper trim,—
From whence we learn, with no great stretch of art,
Five lines hence comes a ghost, and lo! a start.
When he appears most perfect, still we find
Something which jars upon and hurts the mind.
Whatever lights upon a part are thrown,
We see too plainly they are not his own:
No flame from nature ever yet he caught,
Nor knew a feeling which he was not taught;
