CAPTATOR.

No. 199. TUESDAY, FEBRUARY 11, 1752.

Decolor, obscurus, cilis. Non ille repexam
Cæsariem Regum, nec Candida virginis ornat
Colla, nec insigni splendet per cingula morsu:
Sed nova si nigri videas miracula suai,
Tum pulcros superat cultus, et quldquid Evis
Indus litoribus rubra scrutatur in alga
. CLAUDIANUS, xlviii. 10.

Obscure, unpris'd, and dark, the magnet lies,
Nor lures the search of avaricious eyes,
Nor binds the neck, nor sparkles in the hair,
Nor dignifies the great, nor decks the fair.
But search the wonders of the dusky stone,
And own all glories of the mine outdone,
Each grace of form, each ornament of state,
That decks the fair, or dignifies the great.

TO THE RAMBLER.
SIR,

Though you have seldom digressed from moral subjects, I suppose you are not so rigorous or cynical as to deny the value or usefulness of natural philosophy; or to have lived in this age of inquiry and experiment, without any attention to the wonders every day produced by the pokers of magnetism and the wheels of electricity. At least, I may be allowed to hope that, since nothing is more contrary to moral excellence than envy, you will not refuse to promote the happiness of others, merely because you cannot partake of their enjoyments.

In confidence, therefore, that your ignorance has not made you an enemy to knowledge, I offer you the honour of introducing to the notice of the publick, an adept, who, having long laboured for the benefit of mankind, is not willing, like too many of his predecessors, to conceal his secrets in the grave.

Many have signalized themselves by melting their estates in crucibles. I was born to no fortune, and therefore had only my mind and body to devote to knowledge, and the gratitude of posterity will attest, that neither mind nor body have been spared. I have sat whole weeks without sleep by the side of an athanor, to watch the moment of projection; I have made the first experiment in nineteen diving engines of new construction; I have fallen eleven times speechless under the shock of electricity; I have twice dislocated my limbs, and once fractured my skull, in essaying to fly[l]; and four times endangered my life by submitting to the transfusion of blood.
