sight is reflected to the sun,Cesc Fabregas Drakt.
The mirrors must be thought of as contiguous: each of them is too small to be visible, but their contiguity makes the whole made up of them all to seem one. The bright band is the sun, which is seen as a circle,Russland Landslagsdrakt, appearing successively in each of the mirrors as a point indivisible to sense. The band of cloud next to it is black,Rainbow International Bunda, its colour being intensified by contrast with the brightness of the halo. The halo is formed rather near the earth because that is calmer: for where there is wind it is clear that no halo can maintain its position.
Haloes are commoner round the moon because the greater heat of the sun dissolves the condensations of the air more rapidly.
Haloes are formed round stars for the same reasons,Bailey Button Triplet 1873, but they are not prognostic in the same way because the condensation they imply is so insignificant as to be barren.

We have already stated that the rainbow is a reflection: we have now to explain what sort of reflection it is, to describe its various concomitants,Parajumpers Damen Alaska, and to assign their causes.
Sight is reflected from all smooth surfaces, such as are air and water among others. Air must be condensed if it is to act as a mirror, though it often gives a reflection even uncondensed when the sight is weak. Such was the case of a man whose sight was faint and indistinct. He always saw an image in front of him and facing him as he walked. This was because his sight was reflected back to him. Its morbid condition made it so weak and delicate that the air close by acted as a mirror,Storm Yd, just as distant and condensed air normally does, and his sight could not push it back. So promontories in the sea ‘loom’ when there is a south-east wind, and everything seems bigger,Colo-Colo Drakt, and in a mist, too, things seem bigger: so,Damskie Barbour Betty Interactive Liner, too,Air Jordan Retro 11 Damskie, the sun and the stars seem bigger when rising and setting than on the meridian. But things are best reflected from water,Kevin De Bruyne Drakt, and even in process of formation it is a better mirror than air,Belstaff Nové Panther Bunda, for each of the particles, the union of which constitutes a raindrop,Classic Czyścibut 5251, is necessarily a better mirror than mist. Now it is obvious and has already been stated that a mirror of this kind renders the colour of an object only, but not its shape. Hence it follows that when it is on the point of raining and the air in the clouds is in process of forming into raindrops but the rain is not yet actually there, if the sun is opposite, or any other object bright enough to make the cloud a mirror and cause the sight to be reflected to the object then the reflection must render the colour of the object without its shape. Since each of the mirrors is so small as to be invisible and what we see is the continuous magnitude made up of them all, the reflection necessarily gives us a continuous magnitude made up of one colour; each of the mirrors contributing the same colour to the whole. We may deduce that since these conditions are realizable there will be an appearance due to reflection whenever the sun and the cloud are related in the way described and we are between them. But these are just the cond
