Cronstedt gives it as his opinion, that ignes fatui, as well as falling stars, are owing to collections of inflammable air raised to a great height in the atmosphere. But, with regard to the latter, the vast height at which they move, evidently shews that they cannot be the effect of any gravitating vapour whatever; for the lightest inflammable air is one-twelfth of that of the common atmosphere: and we have no reason to believe, that at the distance of forty or fifty miles from the earth, the latter has near one-twelfth of its weight at the surface. From the account given by Mr. Warltire, we should be apt to conclude, that there is a strong affinity betwixt the ignes fatui and fireballs, insomuch that the one might be very easily converted into the other. Electricity can assume both these appearances, as is evident in the case of points; or even when the atmosphere is violently electrified, as around the string of an electrified kite, which always will appear to be surrounded with a blue flame in the night, if the electricity be very strong. On the whole, it appears that electricity, acting upon a small quantity of atmospherical air with a certain degree of vigour, will produce an appearance resembling an ignis fatuus; with a superior force it will produce a fire-ball; and a sudden increase of electrical power might produce those sparks and apparent explosions observed by Mr. Warltire. This appearance has produced many superstitious fears in the ignorant and uneducated.
To those who have, unfortunately, been badly educated in this respect, a friendly act would be, to endeavour with sound reasoning to convince them of their error, and dissuade them from giving heed, in future, to idle, superstitious, or inconsistent stories of any kind; advising them to furnish themselves with such knowledge, as may have a tendency to produce true pleasure and happiness through life, and which, when dying, they can reflect upon without uneasiness. “The natural offspring of prevailing superstition is infidelity. Of the truth of this, the present times afford us a lamentable example. Where ignorance and fear once ruled supreme, there has rash philosophy but too successfully planted presumption and atheism. ’Tis the diffusion of pure and solid knowledge, which alone can preserve us from the dominion of these opposite tyrants. How should this consideration increase our zeal and stimulate our endeavours! The immediate sphere of our action may be circumscribed, but our exertions will not on that account be entirely lost. In that circumscribed sphere let us labour to root out every superstitious lying vanity, and plant pure religion and unsophisticated truth in its stead.
“How charming, how enlivening to the soul, to gaze upon the dawning beams of opening light, to behold them irradiate that dismal gloom of intellectual darkness, which long overwhelmed the millions of mankind: how supremely pleasing, to view them wider and wider spreading their invigorating influence: how rapturously transporting, to contemplate the resplendent prospect of pure and perfect day!
“——————Power supreme!
O everlasting King! to thee we kneel,
To thee we lift our voice!”—
“O spread thy benign, thy vivifying light over the dwellings of the sons of men; dispel the yet impending mists of ignorance and superstition: and, O preserve us from the dismal gulf of infidelity and atheism; let thy truth run and prevail gloriously; let pure celestial wisdom overspread the earth as the waters cover the sea!—Then shall millions kneel before thee with grateful and enraptured hearts; then shall they rejoice to sing the praises of thee, their Benefactor, their Father, and their God: then shall this vale of tears be filled with the mansions of joy and gladness, and become a blissful foretaste of those regions, where thy saints, crowned with unfading glory and felicity, surround thy throne with never-ceasing hallelujahs!”
