"In the horizontal or lateral reflections, the mirage represents the reflected image sideways. Thus, on the 17th of September, 1818, M. Jurine and Soret observed a lateral mirage on the lake of Geneva. A bark, about four thousand toises distant, was seen approaching Geneva by the left bank of the lake, and at the same moment there was seen above the water an image of the sails, which, in place of following the direction of the bark, receded from it, and seemed to approach Geneva by the right bank of the lake, the image sailing from east to west, while the bark was sailing from north to south. This lateral mirage is known to the inhabitants of Meroa, who call it _Si-koté_, (castle of the cold season;) by those who live on the plains watered by the Chumbul and the Jumna, it is termed _Dissaser_, (prognostic.) "In particular situations, both the _vertical_ and _lateral_ mirage may be observed together. Thus the late Mr. Blackadder has described some phenomena, both of vertical and lateral mirage, as seen at king George's Bastion, Leith, which are very instructive. "The phenomenon called _suspension_, which is the third kind of mirage, and to which the term _looming_ is most strictly applied, is the picturing of an object immediately over it in the air, frequently without reversion of the image. Sometimes the objects are merely raised above the height at which, under ordinary circumstances, they would appear. Thus sir R. K. Porter mentions a phenomenon of suspension, or _looming_, in the plains near Bagdad. 'A little before morning,' says he, 'I observed an elevated stream of water, which, from its situation, must be the Tigris. Its surface was brilliantly illuminated by the moon, but the longer I kept my eye fixed on this noble river of many interests, the more my surprise became excited at the extraordinary height of its waters above the level of the desert, till at length I began to suspect that some optical illusion from refraction was assisting the apparent elevation of the stream; but I had not conceived the extent of the deception, for as the dawn advanced the phantom river totally sunk from my sight.' The phenomenon of _looming_ is most generally observed at sea, or near the shore. At Reggio, in Calabria, the _Fata Morgana_ (Fairy Morgana) is visible, which for many centuries astonished the vulgar and perplexed philosophers. "It frequently happens that the phenomenon of the _vertical_ mirage is combined with that of _suspension_, so as to show in the air both a direct and an inverted image of the subject, the latter being undermost.
