Wondrous Machine! which can by magick Light,
Mature an embryo Atome to the Sight.
Full to our View which can, in unform'd Clay,
An Insect, working into Form, display;
And thro' whose mystick Power, a Gyant Size
Or does, or seems, from Miniature to rise
See! Ripe in Mirrour, see! the Egg-Worm sleep,
And, e'er his Shell is broke, proportion'd creep.
Parts, yet imperfect, now appear compleat;
Tho' mix'd, yet sever'd; tho' minute, yet, great.
Hail mighty Crystal! whose most powerful Light,
To Order Chaos turns; to Day the Night.

Consult the Glass, and see yon puny Flea;
Disturber Cynthia of thy Dreams and Thee!
See! with what monstrous Port and stately Pride,
The Pigmy swells, and tempts an awker'd Stride;
See his Proboscis ! see his well-hing'd Thigh;
His Lobster-Legs; and see his Eagle-Eye.

O Microscopia ! Goddess heavenly bright,
Which to an Angel's Ken has stretch'd my Sight,
Stop not thy Bounty, but be still more kind,
Enlarge the Purlieu of my narrow Mind:
In Colours, plain, expose to Reason's Eye,
What, yet, to Reason Nature does deny:
What 'tis to think, teach my amazed Thought;
And let, O! let me, whence I came , be taught;
Be taught, what am I ? Where, at Death, I go?
What Spirits do above, what Shades, below?
Open of future Scenes the hidden Doom;
Explain the present and the Things to come;
And then, in pious Hymns and grateful Lays,
O Goddess! I'll enshrine thy deathless Praise.
