Remarkable Phenomena.—January 18th. This morning a parhelion appeared around the sun as he rose, consisting of a mock sun, or image of the sun on each side of him in a horizontal line. From the image northward of the sun there issued a cone of light, the vertex of which was directed from the sun. There was no halo, and the mock suns were not well defined by any outline, though the morning was fair, and the sun shone bright. At eight o'clock the distance of the mock suns from each other, measured by a sextant, was found to be 44° 40´. At half past eight they had assumed the appearance of extended planes perpendicular to the horizon, and about 5° or 6° in length; breadth a little more than sun's diameter; soon after which they disappeared. N. B. See Remarkable Phenomena continued, on page lxviii [our page [288]], at the conclusion of the Meteorological Register.
