An Amsterdam reprint of the earliest exhaustive treatise on the aurora borealis, two quarto editions of which had previously been published at Paris in 1733 and 1734. Mairan attributed the phenomenon of the aurora borealis to an extension of the sun's atmosphere, which at times, he supposed, enveloped the Earth, and blended with our atmosphere. The zodiacal light was similarly accounted for.
