Many years ago a double-image micrometer, in which the images were formed by the double refraction of a sphere of quartz, was prepared by Mr Dollond for Capt. Smyth, R.N.

It confirmed me in my belief that about Jesus we must believe no one but Himself, and that what we have to do is to discover the true image of the Founder behind all the prismatic refractions through which it comes to us, and which alter it more or less.

The country was covered with thick scrub, and some patches of gum and wattle thicket; about noon it was more open, and ascending an elevated sandy ridge, saw apparently a high range of hills extending north-north-west as far as Shark Bay, and terminated by a very abrupt and detached hill; but the excessive refraction caused by the heated and nearly level plain which intervened more than doubled their real height.

He predicted "conical refraction," afterwards experimentally proved by another Irishman, Humphrey Lloyd.

'Relying on this, we have now computed our mean refractions by diminishing those of Bessel's Fundamenta in the proportion of 1 to 0.99797.'The

The envelope of his spiritual nature was so tenuous that he seemed to respond to all the subtler influences of the universe; a sensitive chord attuned to poetic values, he appeared to exercise an almost mediumistic refraction and revelation of matters which lie only in the realm of the transcendental "Weaving about the commonplace of things The golden haze of morning's blushing glow.

As she travelled deeper and deeper, it was a wonder to see how far that little ray penetrated down and down through gulfs of darkness, blue and cold like the shimmer of a diamond, and even when it could be seen no more, sent yet a shadowy refraction, a line of something less black than the darkness, a lightening amid the gloom, a something indefinable which was hope.

Terrestrial refraction is the same thing, occurring whenever there is a difference of density in the aerial strata.

He noted that atmospheric refraction would alter with the height of the atmosphere and with temperature, and also recognised the fact that rainbow colours depend on the angle of refraction, whether seen in the rainbow itself, or in dew, glass, water, or any similar medium.

My data are the distance at which they were seen from Kewewena portage, under the influence of great refraction, and the distance on the following day without unusual refraction, and I am convinced they cannot be less than 2000 feet high; if, however, this staggers you, say 1800, and I am confident you are within the real elevation.

A gleam of their divine refraction swam before her.

It is laid down, that, where extraordinary refraction takes place laterally or vertically, the visual angle of the spectator is singularly enlarged, and objects are magnified, as if seen through a telescope.

A tremulous crystal, waved as water, poured out upon the ground;you may defile it, despise it, pollute it at your pleasure and at your peril; for on the peace of those weak waves must all the heaven you shall ever gain be first seen; and through such purity as you can win for those dark waves must all the light of the risen Sun of Righteousness be bent down by faint refraction.
