Decolor, obscurus, cilis. Non ille repexam
Caesariem 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.

In the first period of my studies, I exerted the powers of my body more than those of my mind, and was not without hopes that fame might be purchased by a few broken bones without the toil of thinking; but having been shattered by some violent experiments, and constrained to confine myself to my books, I passed six-and-thirty years in searching the treasures of ancient wisdom, but am at last amply recompensed for all my perseverance.

The curiosity of the present race of philosophers, having been long exercised upon electricity, has been lately transferred to magnetism; the qualities of the loadstone have been investigated, if not with much advantage, yet with great applause; and as the highest praise of art is to imitate nature, I hope no man will think the makers of artificial magnets celebrated or reverenced above their deserts.

I have, for some time, employed myself in the same practice, but with deeper knowledge and more extensive views. While my contemporaries were touching needles and raising weights, or busying themselves with inclination and variation, I have been examining those qualities of magnetism which may be applied to the accommodation and happiness of common life. I have left to inferior understandings the care of conducting the sailor through the hazards of the ocean, and reserved to myself the more difficult and illustrious province of preserving the connubial compact from violation, and setting mankind free for ever from the danger of supposititious children, and the torments of fruitless vigilance and anxious suspicion.
