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.
If any rays missed their bodies, the sand reflected it to them.
The rays of the sun fell upon the trees, so that the twigs sparkled like diamonds and dropped in showers when we touched them.
They seemed to walk for hours, until the first rays of morning lightened the forest.
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.
We barely slept that night, in eager anticipation of glimpsing our first rays of sunshine!
The hidden sun was setting, and the white snow clouds glowed eerily, lit by the last rays of light.
The hours passed without another scream and she was still sitting at the table when the first rays of morning light warmed the kitchen.
In this tissue fresh bundles may become differentiated, and what remains of it becomes the rays of the fully-formed stele.
The intensity of the light scattered by a small particle is constant, and a maximum, for rays which lie in the vertical plane running east and west, while there is no scattered ray along the north and south line.
It is obvious that the aerial particles are illuminated not only by the direct solar rays, but also by light dispersed from other parts of the atmosphere and from the earth's surface.
If the stellar spectrograph is viewed in the focus of 0 2 and the converging rays are reflected by the prism P2 to P4, no image would be seen in the eyepiece, for the rays would pass out directly through the parallel glass plate which is formed by the cementing together of the prisms P 3 and P 4.
The Golden Temple is so called on account of its copper dome, covered with gold foil, which shines brilliantly in the rays of the Indian sun, and is reflected back from the waters of the lake; but the building as a whole is too squat to have much architectural merit apart from its ornamentation.
The oil when brought to the surface has the appearance of a whitish-blue water, which gives out brilliant straw-coloured rays, and emits a strong pungent odour.
The chief of his other contributions to optics was the explanation of the rainbow - an explanation far from complete, since the unequal refrangibility of the rays of light was yet undiscovered - but a decided advance upon his predecessors, notably on the De radiis visas et lucis (1611) of Marc-Antonio de Dominis, archbishop of Spalato.
There he continued his researches on the discharge of electricity in rarefied gases, only just missing the discovery of the X-rays described by W.
These collateral bundles are separated from one another by bands of conjunctive tissues called primary medullary rays, which may be quite narrow or of considerable width.
The pericycle, medullary rays, endocycle and mesoderm all form parts of one tissue system, the external conjunctive, and are only topographically separable.
Among Gymnosperms the secondary xylem is similarly simple, consisting of tracheids which act as stereom as well as hydrom, and a little amylom; while the phloem-parenchyma sometimes undergoes a differentiation, part being developed as amylom, part as proteid cells immediately associated with the sieve-tube, in other cases the proteid cells of the secondary phloem do not form part of the phloem-parenchyma, but occupy the top and bottom cellrows of the medullary rays, the middle rows consisting of ordinary starchy cells.
In the latter event the cells of the primary rays are either merely stretched radially, or they divide to keep pace with the growth of the bundles.
Periderm; c, cortex; ph, phlocni with alternating strands of fibres, sieve-tubes and parenchyma; ~r.r, principal ray; Sr., subordinate rays; ca, cambium.
In either case, narrow, secondary rays are formed at intervals, just as in the stem.
The rays which in the absence of the solution of chlorophyll would have occupied those spaces have no power to pass through it, or in other words chlorophyll absorbs those particular rays of light which are missing.
The absorption of these rays implies that the pigment absorbs radiant energy from the sun, and gives us some explanation of its power of constructing the carbohydrates which has been mentioned as the special work of the apparatus.
There is a certain amount of evidence that at any rate in some cases light is necessary, and that the violet rays of the spectrum are chiefly concerned.
The source of energy which is the only one accessible to the ordinary plant as a whole is the radiant energy of the rays of the sun, and its absorption is mainly due to the properties of chlorophyll.
This coloring matter, as shown by its absorption spectrum, picks out of the ordinary beam of light a large proportion of its red and blue rays, together with some of the green and yellow.
It has been suggested by several botanists, with considerable plausibility, that the ultra-violet or chemical rays can be absorbed and utilized by the protoplasm without the intervention of any pigment such as chlorophyll.
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.
In species of Eucalyptus, the leaves are placed edge-wise to the incident rays of light and heat.
Some plants of changing their position in the cell under the stimulus of a variation in the intensity of the light rays which fall upon them.
The difference between the heating power of the sun's rays at noon on the 21st of June, in latitude 20° and in latitude 45°, is only about 2%; while the accumulated heat received during the day, which is lengthened to 152 hours in the higher latitude, is greater by about i i% than in the lower latitude, where the day consists only of 134 hours.
The saw-fishes, Pristidae, the electrical rays, Torpedinae, and ordinary rays and skates, are also found in considerable numbers.
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.
" The subsidiary rays of medals and inscriptions, of geography and chronology, were thrown on their proper objects; and I applied the collections of Tillemont, whose inimitable accuracy almost assumes the character of genius, to fix and arrange within my reach the loose and scattered atoms of historical information."
On the thick layer of black earth by which the steppe is covered a luxuriant vegetation develops in spring; after the old grass has been burned a bright green prevails over immense stretches, but this rapidly disappears under the burning rays of the sun and the hot E.
HADDOCK (Gadus aeglefinus), a fish which differs from the cod in having the mental barbel very short, the first anal fin with 22 to 25 rays, instead of 17 to 20, and the lateral line dark instead of whitish; it has a large blackish spot above each pectoral fin - associated in legend with the marks of St Peter's finger and thumb, the haddock being supposed to be the fish from whose mouth he took the tribute-money.
Arctic plants make their brief growth and flower at a temperature little above freezing-point, and are dependent for their heat on the direct rays of the sun.
The response to the action of light in diatropic leaves is, according to Haberlandt, due to the presence of epidermal cells which are shaped like a lens, or with lens-shaped thickenings of the cuticle, through which convergence of the light rays takes place and causes a differential illumination of the lining layer of protoplasm on the basal walls of the epidermal cells, by which the stimulus resulting in the orientation of the leaf is brought about.
Companion cells are not found in the Pteridophyta and Gymnosperms. In the latter their place is taken by certain cells of the medullary rays and bast parenchyma.
The differentiation of the stelar stereom, which usually takes the form of a sclerized pericycle, and may extend to the endocycle and parts of the rays, takes place in most cases later than the formation of the primary vascular strand.
