And since the pupil of the eye receives
Within itself one kind of blow, when said
To feel a white hue, then another kind,
When feeling a black or any other hue,
And since it matters nothing with what hue
The things thou touchest be           endowed,
But rather with what sort of shape equipped,
'Tis thine to know the atoms need not colour,
But render forth sensations, as of touch,
That vary with their varied forms.
