Abstract
In some of the last volumes of the Philosophical Transactions, there have been related many instances of strong atmospherical refraction, by which, objects seen near the horizon have appeared inverted, and the horizon itself either elevated or depressed. Mr. Huddart first took notice of a distinct image, inverted beneath the object itself; and, in the Philosophical Transactions for 1797, has described several such appearances, accompanied with an optical explanation, wherein he shews, that the lowest strata of the air were at the time endued with a weaker refractive power, than others at a small elevation.Keywords
