If any rays missed their bodies, the sand reflected it to them.

Half way up the steep was a yawning cave, black as night beyond the point where the rainbow rays of the colored suns reached into it.

Below, the house was bathed in the first rays of morning sun.

They seemed to walk for hours, until the first rays of morning lightened the forest.

The hidden sun was setting, and the white snow clouds glowed eerily, lit by the last rays of light.

The rays of the sun fell upon the trees, so that the twigs sparkled like diamonds and dropped in showers when we touched them.

We barely slept that night, in eager anticipation of glimpsing our first rays of sunshine!

Speak of the sun and you see its rays! and she smiled amiably at Pierre.

In either case, narrow, secondary rays are formed at intervals, just as in the stem.

And by some latent sequence of thought the descent of the Mozhaysk hill, the carts with the wounded, the ringing bells, the slanting rays of the sun, and the songs of the cavalrymen vividly recurred to his mind.

Soil temperature is partly dependent on the direct rays of the sun, partly on the color and constitution of the soil, and partly on the water content of the soil.

Remaining itself in repose, it rays out, as it were, from its own fullness an image of itself, which is called vas, and which constitutes the system of ideas of the intelligible world.

The insects are guided by light, being very sensitive to ultra-violet rays, and also by scent and hearing.

In this all-important doctrine of the Sephiroth, the Kabbalah insists upon the fact that these potencies are not creations of the En Soph, which would be a diminution of strength; that they form among themselves and with the En Soph a strict unity, and simply represent different aspects of the same being, just as the different rays which proceed from the light, and which appear different things to the eye, are only different manifestations of one and the same light; that for this reason they all alike partake of the perfections of the En Soph; and that as emanations from the Infinite, the Sephiroth are infinite and perfect like the En Soph, and yet constitute the first finite things.

Prisms deflect rays of light towards their bases.

The rays of this star spend close upon a century in travelling hither.

The rays may lie very close together, or may be widely separated from one another.

And that this is the intire and adequate cause of their colours, is manifest, because they have no power to change or alter the colours of any sort of Rays incident apart, but put on all colours indifferently, with which they are inlightened.

These rays come to a focus at a point F lying in the focal plane of the telescope.

The cones of rays issuing from a point situated only a little to the FIG.

A similar six-rayed system of cracks, bisecting the angles between the rays of the previous set, is produced when a blunt punch is gradually pressed against a sheet of mica; this is known as the "pressure figure."

It is equal to the actual diameter of the cylinder of rays admitted by a telescope.

Theory and experiment alike prove that a double line, of which the components are equally strong, is better resolved when, for example, one-sixth of the horizontal aperture is blocked off by a central screen; or the rays quite at the centre may be allowed to pass, while others a little farther removed are blocked off.

The extreme discrepancy is that between the waves which travel through the outermost parts of the object-glass at L and L'; so that if we adopt the above standard of resolution, the question is where must P be situated in order that the relative retardation of the rays PL and PL' may on their arrival at B amount to a wave-length (X).

If 8 and 4' denote the angles with the normal made by the incident and diffracted rays, the formula (5) still holds, and, if the deviation be reckoned from the direction of the regularly reflected rays, it is expressed as before by (0+0), and is a minimum when 8 = 0, that is, when the diffracted rays return upon the course of the incident rays.

Then the relative retardation of the extreme rays (corresponding to the edges A, B of the grating) is mnX.

If BQ be the direction for the first minimum (the darkness between the central and first lateral band), the relative retardation of the extreme rays is (mn+1)X.

The irregularity of spacing has thus the effect of a convex lens, which accelerates the marginal relatively to the central rays.

It may be remarked that these calculations apply to the rays in the primary plane only.

The experiment is easily made on a laboratory scale, with a small source of light, the rays from which, in their course towards a rather distant screen, are disturbed by the neighbourhood of a heated body.

The proportionality of the secondary disturbance to sin 43 is common to the present law and to that given by Stokes, but here there is no dependence upon the angle 0 between the primary and secondary rays.

Among the Greeks and Romans various speculations as to the cause of the how were indulged in; Aristotle, in his Meteors, erroneously ascribes it to the reflection of the sun's rays by the rain; Seneca adopted the same view.

So far we have only considered rays of homogeneous light, and it remains to investigate how lights of varying refrangibilities will be transmitted.

Taking the refractive index of water for the red rays as 0;, and for the violet rays as 1 r, we can calculate the following values for the minimum deviations corresponding to certain assigned values of n.

To this point we have only considered rays passing through a principal section of the drop; in nature, however, the rays impinge at every point of the surface facing the sun.

It may be readily deduced that the directions of minimum deviation for a pencil of parallel rays lie on the surface of cones, the semi-vertical angles of which are equal to the values given in the above table.

This was first suggested by Thomas Young, who showed that the rays producing the bows consisted of two systems, which, although emerging in parallel directions, traversed different paths in the drop. Destructive interference between these superposed rays will therefore occur, and, instead of a continuous maximum illumination in the direction of minimum deviation, we should expect to find alternations of brightness and darkness.

Marine rainbow is the name given to the chromatic displays formed by the sun's rays falling on the spray drawn up by the wind playing on the surface of an agitated sea.

They are formed by parallel rays of light emanating from two sources, as, for example, the sun and its image in a sheet of water, which is situated between the observer and the sun.

The action of the sun's rays stimulates the cells of the skin to increase the pigment as a protection to the underlying tissues, e.g.

Among the revisions may be adduced some addition to our knowledge of dyspepsia, attained by analytic investigations into the contents of the stomach at various stages of digestion, and by examining the passage of opaque substances through the primae vine by the Rntgen rays.

The discovery of the Rntgen rays has also extended the physician's power of vision, as in cases of aortic aneurysm, and other thoracic diseases.

The temperature required in the fusion of sheet-glass and of other glasses produced in tank furnaces is much lower than that attained in steel furnaces, and it is consequently pos Since the discovery of the Rntgen rays, experiments have been made to ascertain the effects of the different constituents of glass on the transparency of glass to X-rays.

The oxides of lead, barium, zinc and antimony are found perceptibly to retard the rays.

The glass tubes, therefore, from which the X-ray bulbs are to be fashioned, must not contain any of these oxides, whereas the glass used for making the funnel-shaped shields, which direct the rays upon the patient and at the same time protect the hands of the operator from the action of the rays, must contain a large proportion of lead.

This elaborate type of scolex appears to be an adaptation to grasp the spiral intestinal valve of sharks and rays.

His work won him the Rumford medal of the Royal Society in 1838, and in 1843 he received its Royal medal for a paper on the "Transparency of the Atmosphere and the Laws of Extinction of the Sun's Rays passing through it."

About the same time Francesco Maurolico, or Maurolycus, the eminent mathematician of Messina, in his Theore y nata de Lumine et Umbra, written in 1521, fully investigated the optical problems connected with vision and the passage of rays of light through small apertures with and without lenses, and made great advances in this direction over his predecessors.

He discloses as a great secret the use of a concave speculum in front of the aperture, to collect the rays passing through it, when the images will be seen reversed, but by prolonging them beyond the centre they would be seen larger and unreversed.

All objects, therefore, which lie beyond a certain point (the conjugate focus of the dioptric system of the eye, the far point) are indistinctly seen; rays from them have not the necessary divergence to be focused in the retina, but may obtain it by the interposition of suitable concave lenses.
