In my view, the Christian religion is the most important and one of the first things in which all children, under a free government ought to be instructed... No truth is more evident to my mind than that the Christian religion must be the basis of any government intended to secure the rights and privileges of a free people. Preface to 1828 Dictionary

RA'INBOW, n. A bow, or an arch of a circle, consisting of all the colors formed by the refraction and reflection of rays of light from drops of rain or vapor, appearing in the part of the hemisphere opposite to the sun. When the sun is at the horizon, the rainbow is a semicircle. The rainbow is called also iris.
A bow or arch exhibiting, in
concentric bands, the several colors of the spectrum, and formed in
the part of the hemisphere opposite to the sun by the refraction and
reflection of the sun's rays in drops of falling rain.
* Besides the ordinary bow, called also primary rainbow, which is formed by two refractions and one reflection, there is also another often seen exterior to it, called the secondary rainbow, concentric with the first, and separated from it by a small interval. It is formed by two refractions and two reflections, is much fainter than the primary bow, and has its colors arranged in the reverse order from those of the latter. Lunar rainbow, a fainter arch or rainbow, formed by the moon. -- Marine rainbow, or Sea bow, a similar bow seen in the spray of waves at sea. -- Rainbow trout (Zoöl.), a bright-colored trout (Salmo irideus), native of the mountains of California, but now extensively introduced into the Eastern States, Japan, and other countries; -- called also brook trout, mountain trout, and golden trout. -- Rainbow wrasse. (Zoöl.) See under Wrasse. -- Supernumerary rainbow, a smaller bow, usually of red and green colors only, sometimes seen within the primary or without the secondary rainbow, and in contact with them. | ||||||||
