Analysis of A Bit Of Science

What! photograph in colors? 'Tis a dream
And he who dreams it is not overwise,
If colors are vibration they but seem,
And have no being. But if Tyndall lies,
Why, come, then-photograph my lady's eyes.
Nay, friend, you can't; the splendor of their blue,
As on my own beclouded orbs they rest,
To naught but vibratory motion's due,
As heart, head, limbs and all I am attest.
How could her eyes, at rest themselves, be making
In me so uncontrollable a shaking?
