Which in each part of nature's system shine;
Surveys the wonders of this beauteous frame,
And sings the sacred source, whence all things came.

But Oh! what numbers shall I find to tell,
The mighty transports which my bosom swell,
Whilst, guided by thy tuneful voice, I stray
Thro' radiant worlds, and fields of native day,
Wasted from orb, to orb, unwearied fly
Thro' the blue regions of the yielding sky;
See how the spheres in stated courses roll,
And view the just composure of the whole!

Such were the strains, by antient Orpheus sung.
To such, Mufaeus' heav'nly lyre was strung;
Exalted truths, in learned verse they told,
And nature's deepest secrets did unfold.
How at th' eternal mind's omnisic call,
Yon starry arch, and this terrestrial ball,
The briny wave, the blazing source of light,
And the wane empress of the silent night,
Each in it's order rose and took its place,
And filled with recent forms the vacant space;
How rolling planets trace their destin'd way,
Nor in the wastes of pathless AEther stray;
How the pale moon, with silver beams adorn
Her chearful orb, and gilds her sharpened horns;
How the vast ocean's swelling tides obey
Her distant reign, and own her watr'y sway;
How erring floods, their circling course maintain,
Supplied by constant succours from the main;
Whilst to the sea, the refluent streams restore,
The liquid treasures which she lent before;
What dreadful veil obscures the solar light,
And Phaebe's darken'd face conceals from mortal sight.
Thy learned muse, I with like pleasure hear
The wonders of the lesser world declare,
Point out the various marks of skill divine,
Which thro' its complicated structure mine,
In tuneful verse, the vital current trace,
Thro' all the windings of its mazy race,
And tell hew the rich purple tide bestows,
Vigour, and kindly warmth where e'er it flows;
By what contrivance of mechanic art
The muscles, motions to the limbs impart;
How at th' imperial mind's impulsive nod,
Th' obedient spirits thro' the nervous road
Find thro' their fib'rous cells the ready way,
And the high dictates of the will obey;
From how exact and delicate a frame,
The channeled bones their nimble action claim;
With how much depth, and subtility of thought
The curious organ of the eye is wrought;
How from the brain their root the nerves derive,
And sense to ev'ry distant
