Optical Phenomena

Abstract

IN connection with different singular atmospheric phenomena noticed lately in India, Ceylon, and even in our own country, I think an extract from a letter received by the last Cape mail may prove of interest to some of your readers. I may premise that my correspondent resides upon an open Karoo plain, where the atmosphere is always clear; such a “phenomenon” as a fog being unknown, and where the sunsets generally are of a beauty that I have rot seen surpassed even in the tropics, a beauty, however, very evanesctnt, for it will be remembered that in those latitudes there is little or no twilight.
