"Undulation" Quotes from Famous Books



... which these and other such facts can be rapidly expressed; if you copy it carefully, you will be surprised to find how the touches all group together, in expressing the plumy toss of the tree branches, and the springing of the bushes out of the bank, and the undulation of the ground: note the careful drawing of the footsteps made by the climbers of the little mound on the left.[23] It is facsimiled from an etching of Turner's, and is as good an example as you can have of the use of pure and firm lines; it will also show you how the particular ...

... sound we can employ an acoustic apparatus for the purpose of decomposing any proposed note, and finding not only the main undulation itself, but the several superposed harmonics which give to the note its timbre. So also we can analyze the undulation of the tide, and show the component parts. The decomposition is effected by the process known as harmonic analysis. The principle of the method may ...

... wrong by the strange look on the face of a friendly French peasant whom I met at Gournay. He had described to me in a very vivid way the disposition of the French troops on the neighbouring hills who had disappeared in the undulation below the sky-line, but when I mentioned that I was on the way to Beauvais he suddenly raised his head and looked at me in a queer, startled way which puzzled me. I remember that look when I began to approach the ...

... the most beautiful scazons[664] in the Latin tongue; the metre limps no more; a master-hand has wrought it to exquisite melody; the quiet undulation of the sea, the yacht's easy gliding over its surface, live before us in its music. Even more delicate is the homelier description of the gardens of Julius Martialis on the slopes of the Janiculum. It is animated by the sincerity that never fails Martial when he writes ...

... the reader by explaining the simple process that carried us happily through the deluge. By keeping the canoe bow on, we nobly resisted the shock of every wave, and gradually fell back under the impulse of each undulation. Thus we held on till the heavy clouds discharged their loads, beating down the sea and half filling the canoe with rain water. While the Krooman paddled and steered, I conducted the bailing, and as the African dipper was not sufficient to keep us free, I pressed my Panama hat into service ...

... tone and a soft continuously-singing upper voice, and you will get the right idea of his playing. But it would be an error to think that Chopin permitted every one of the small notes to be distinctly heard. It was rather an undulation of the A flat major chord, here and there thrown aloft anew by the pedal. Throughout all the harmonies one always heard in great tones a wondrous melody, while once only, in the middle of the piece, besides that chief song, a tenor voice became prominent in the midst ...

... Waterloo, position does not impress the beholder with any sense of strength. The so-called valley, separating the two arrays, is a very shallow depression, nowhere more than fifty feet below the top of the northern slope. It is divided about halfway across by an undulation that affords good cover to assailants about to attack La Haye Sainte. Another slight rise crosses the vale halfway between this farm and Hougoumont, and facilitates the approach to that part of the ridge. In fact, only on their extreme ...

... up. Something scuffled. It was a little, brown squirrel running in lovely, undulating bounds over the floor, its red tail completing the undulation of its body—and then, as it sat up, furling and unfurling. He watched it, pleased. It ran on friskily, enjoying itself. It flew wildly at another squirrel, and they were chasing each other, and making little scolding, chattering ...

... beaten about 'Oval Harbour,' as he named the place, for half an hour, before he was struck by the circumstance that the even character of its surface appeared to be a little disturbed by a slight undulation which seemed to come from its north-eastern extremity. Tacking the Bridget, he stood in that direction, and on reaching the place, found that there was a passage through the rock of about a hundred yards in width. The wind permitting, the boat shot through ...

A bird's-eye view of the station itself might have suggested to the imaginative eye a game of noughts and crosses scratched on a Titanic slate:—a network of wide white roads, unrelieved by curve or undulation; their rigidity emphasised by equidistant lines of trees, and ...

... on his lips, for the brown thing behind the chair had slipped upward with the silent undulation of a panther, and a deadly roomal (towel) had flashed over the Chief's head and was now a strangling knot about his tawny throat; the hard knuckles of Hunsa were kneading his spine at the back of the skull with a half twist of the cloth. He was pinioned to the ...

... surfaces towards the snow-field, and on the other stooping in one tremendous cliff to a distorted glacier thousands of feet below. The faint blue line across the upper neve, scarcely distinguishable to the eye, represents to one observer nothing but a trifling undulation; a second, perhaps, knows that it means a crevasse; the mountaineer remembers that it is the top of a huge chasm, thirty feet across, and perhaps ten times as deep, with perpendicular sides of glimmering blue ice, ...

... hills, rolling together, flung off from each other, an endless undulation.

... husband of his sister, Mme. de Cambremer. This rapid recovery caused a sort of tense muscular wave to ripple over Legrandin's hips, which I had not supposed to be so fleshy; I cannot say why, but this undulation of pure matter, this wholly carnal fluency, with not the least hint in it of spiritual significance, this wave lashed to a fury by the wind of an assiduity, an obsequiousness of the basest sort, awoke my mind suddenly to the possibility of a Legrandin altogether different from the one ...

The troops had disappeared, hidden by an undulation of the ground; but over yonder, on the side of the Nores plain, the insurgents soon perceived the bayonets shooting up, one after another, like a field of steel-eared corn under the rising sun. At that moment Silvere, who was glowing with feverish ...

... slumbered on! One—two—three—four quarters after eleven tinkled in silvery numbers upon the delicate bell of the clock, yet the closed eyelids and fixed lips moved not, gave no sign; but for the light, though regular undulation of the chest, life itself might seem to have fled forever. Yet life ...

... the refraction and reflection from a Ball of Water or Glass, we have much the same Phaenomena, namely, an obliquity of the undulation in the same manner as we have found it here.

... to write mixed Latin and English, so losing the grace of the one and the sense of the other. And, in this point of the diffraction of light I am stopped dead by their confusion of idea also, in using the words undulation and vibration as synonyms. "When," says Professor Tyndall, "you are told that the atoms of the sun vibrate at different rates, and produce waves of different sizes,—your experience of water-waves will enable ...

... All the miners are agreed in the statement that the gold abounds most at the swells, or highest points of the waves of rock, and that the scarcely less valuable mispickel appears to follow the same law. The spaces between are not found to be so rich as these points of undulation; and this structure must explain the signal contrast in thickness and productiveness which is everywhere seen in sinking a shaft in this district. As the cutting passes through one of these original swells, the thickness of the vein ...

... identical in many of the essentials. The chief difference between the old way and my new method is in the preparatory work. Now, this will never become a world full of ballet dancers, because not everyone could learn this graceful undulation if they wanted to. (All the more reason, I say, why those who have the talent should profit by it.) Not all of my pupils, nor all of my best pupils in other forms of the art, can hope to become solo artistes in ballet work. I can glance over a class at work in any of my studios, and select the ...

... losses in so mighty a ruin perhaps I ought not to allude. I should not presume even to mention that fatal convulsion which shook all Europe and has since left the nations in that state of agitated undulation which succeeds a tempest upon the ocean, were it not for the opportunity it gives me to declare the bounty of my benefactresses. All my own property went down in the wreck; and the mariner who escapes only with his life can never recur to the scene of his escape ...

... idea of the imposing impression caused by the extremely subitaneous changes to which these waters are subjected. The wide bosom of the lake that sometimes lies motionless and glassy, without a breath of air to cause the slightest undulation, in a very short time may be scourged by a sudden gale. The wild gambols of the waves, accompanied by the roar of the disturbed elements, may well cause the timid to fear; for, as the swell lifts, you would think the bases of the earth are rising beneath it; and, again, when it falls, you would imagine ...

In a note to line 373, canto ii. of the poem, the author sets out with, "The progressive motion of fish beneath the water is produced principally by the undulation of their tails;" and after giving the rationale of the process, he goes on to say that "this power seems to be better adapted to push forward a body in the water than the oars of boats;" concluding ...

... direction of the cemetery, and now found himself at the entrance. The gate was locked, but he climbed over the wall and waded through the snow to the spot where he had sat with her so many summer afternoons. The wicker chair was buried out of sight in a drift. A scarcely-visible undulation in the white level marked the position of the mound, and the headstone had a snow-cap. The cedars stood black in the dim moonlight, and the icy coating of their boughs rattled like candelabra. He stood a few moments near the railing, and then tore ...

... mistake to suppose that the normal state of health is represented by a straight horizontal line, Independently of the well-known causes which raise or depress the standard of vitality, there seems to be—I think I may venture to say there is—a rhythmic undulation in the flow of the vital force. The 'dynamo' which furnishes the working powers of consciousness and action has its annual, its monthly, its diurnal waves, even its temporary ripples, in the current it furnishes. There are greater and lesser curves in the ...

... fragrant twigs, about which humming-birds now and then whirred and fluttered as we startled them, scarcely more brilliant in color than the gorgeous maples which grew in one or two dry and open spots. For three-quarters of an hour our drive continued, until at length a slight undulation broke the level of the sand, and a fence, inclosing a patch of Indian corn, from which the forest had been driven back, betokened for the first time the proximity of some habitation. In fact, having reached the summit of the slope, I found myself in the centre of an irregular ...

... the embodied thought of a human mind. A skilful painter hardly does more for his blank sheet of canvas than the landscape-gardener, the planter, the arranges of trees, has done for the monotonous surface of Blenheim,—making the most of every undulation,—flinging down a hillock, a big lump of earth out of a giant's hand, wherever it was needed,—putting in beauty as often as there was a niche for it,—opening vistas to every point that deserved to be seen, ...

... between the surfaces be rarer than the surrounding mediums; then the impulse reflected at the second surface, meeting a subsequent undulation at the first, will render the particles of the rarer medium capable of wholly stopping the motion of the denser and destroying the reflection, while they themselves will be more strongly propelled than if they had been at rest, and the transmitted light will ...

... Satan. His breath was coming more and more laboured. It seemed to Dan's dim consciousness that some of the spring was gone from that glorious stride which swept on and on with the slightest undulation, like a swallow skimming before the wind; but so long as strength remained he knew that Satan would never falter in his pace. As the delirium swept once more shadow-like on his brain, he allowed himself to fall forward, and wound his fingers as closely as possible in the thick mane. His ...

Gloomily thoughtful, standing with eyes fixed upon those of the great bust of Berenice, he was startled by a sudden cry from within the house, the hoarse yell of a man in agony; it was repeated, and became a long shriek, rising and falling in terrible undulation. He had stepped forward to seek an explanation, when Heliodora's eunuch smilingly came to ...

... could be seen coming from the distance, growing larger and larger as they approached the house and then diminishing again when they had passed it, till they looked like two insects at the end of the long white line which stretched as far as the eye could reach, rising and falling with the undulation of the earth.

... here is an absurdity of a far deeper dye, without we resort to the miraculous, which at once obliterates the connection between cause and effect, which it is the peculiar province of physical science to develop. Let us take another view. The present doctrine of light teaches that light is an undulation of an elastic medium necessarily filling all space; and this branch of science probably rests on higher and surer grounds than any other. Every test applied to it by the refinements of modern skill, strengthens its claims. Here then the Newtonian vacuum is no longer a void. If we get over this ...

The wide bosom of the Tappen Zee lay motionless and glassy, excepting that here and there a gentle undulation waved and prolonged the blue shadow of the distant mountain. A few amber clouds floated in the sky, without a breath of air to move them. The horizon was of a fine golden tint, changing gradually into a pure apple green, and from ...

All these floated and shifted and swept on together with a sort of rhythmic undulation as if keeping time to the music, while across their path dazzling showers and arches of colored fire poured from the palace fronts and the hotels. Every movement of the fairy flotilla was repeated in the illuminated water, every torch-tip and scarlet lantern and flake of green or rosy ...

... the captain of a packet between this country and England told me that he sometimes met with a wave on the Atlantic coming against the wind, perhaps in a calm sea, which indicated that at a distance the wind was blowing from an opposite quarter, but the undulation had travelled faster than it. Sailors tell of "tide-rips" and "ground-swells," which they suppose to have been occasioned by hurricanes and earthquakes, and to have travelled many hundred, and sometimes even two or ...

On all that shore the full sunlight lay. The opposite hills, on the east, were in dainty sunshine and shadow, every undulation, every ridge and hollow, softly marked out. With what wonderful sharp outline the mountain edges rose against the bright sky; how wonderful soft the changes of shade and colour adown their sloping sides; what brilliant little ripples ...

It was a troubling effect, but it had been evanescent; he had forgotten it almost till very unexpectedly he saw her coming down the terrace slow and eager, as if she were restraining herself, and with a rhythmic upward undulation of her whole figure.

The intense heat of the summer sun striking on the dry sand or the saline efflorescence of the desert throws the air over them into such a state of quivering undulation as produces the most wonderful and varying effects, distorting the forms of objects, and rendering the most familiar strange and hard to be recognized.

While composing a little treatise on Eternity, I had the curiosity to place a mirror before me; and ere long saw reflected there, a curious involved worming and undulation in the atmosphere over my head.

During the pain Mnemosyne upheld Her arms as one who prophesied.—At length Apollo shriek'd;—and lo! from all his limbs Celestial * * * * * * * * ...

... of the island, I sailed to Loloway, near the eastern point, one of the loveliest spots in the archipelago. Lofty cliffs flank two sides of a round bay; at the entrance a barrier-reef breaks the swell, which glides in a soft undulation over the quiet water, splashing up on the sandy beach. All around is the forest, hanging in shadowy bowers over the water, and hardly a breeze is astir. The white whale-boat of the Anglican missionary floats motionless ...

... science, and I have not heard anything which can prejudice the case of my august client." Darwin's theory was an explanation of phenomena in Natural History, as the undulatory theory was of the phenomena of light. No one objected to the latter because an undulation of light had never been arrested and measured. Darwin offered an explanation of facts, and his book was full of new facts, all bearing on his theory. Without asserting that every part of that theory ...

... by the Spirit of God to write that the unstable and unbelieving man is like the "wave of the sea driven with the wind and tossed." There are two motions of the waves—one up and down, which we call undulation, the other to and fro, which we call fluctuation. How appropriately both are referred to—"tossed" up and down, "driven" to and fro! The double-minded man lacks steadiness in both respects: his faith has no uniformity of experience, for he is ...

... see strange things," she said; and the prophecy was amply fulfilled. For as they went along the broad path, and came better into view of the splendid undulation of woodland and pasture and fern, when on the one hand they saw the Thames far below them flowing through the green and spacious valley, and on the other hand caught some dusky glimpse of the far white houses of London, it seemed to her that she ...

... if to prop up its senile decay. He tried to interest himself in the various initials and symbols deeply carved in bark, now swollen and half obliterated. As he turned back to the summer-house, he for the first time noticed that the ground rose behind it into a long undulation, on the crest of which the same singular profusion of rose-leaves were scattered. It struck him as being strangely like a gigantic grave, and that the same idea had occurred to the fantastic dispenser of the withered ...

... might be produced by our getting nearer the land. Now again came one of those sullen flaps of the sails, showing that though we might seem to be at rest, the vessel was occasionally moved by no gentle force; and I could distinguish, as I looked eastward, a smooth undulation which seemed rolling away in that direction. Still the sky remained obscured as before, and a gauze-like mist hung over the ocean. The atmosphere felt hotter and more oppressive than ever. The passengers remained on deck, for ...

... flowers containing not less than twenty-five different stones, assorted shades of agate, carnelian, jasper, blood-stone, lapis lazuli, and turquoise. Ere leaving we put to test the celebrated echo; that beautiful echoing, that—"floats and soars overhead in a long, delicious undulation, fading away so slowly that you hear it after it is silent, as you see, or seem to see, a lark you have been watching, after it is swallowed up in ...

... dark stocking from the leg of the road. Three minutes' walk ahead of her, suspended in the now high and limitless air, she saw a thin interlacing of attenuated gleams and glitters, centred in a regular undulation on some one invisible point. Abruptly she knew where she would go. That was the great cascade of wires that rose high over the river, like the legs of a gigantic spider whose eye was the little green light in the switch-house, and ran with the railroad bridge in the direction of the station. ...

... been looking for centuries, and I cannot see it. I supposed we were heading for it. I thought sometimes I saw the flash of distant spires, the sunny gleam of upland pastures, the soft undulation of purple hills. Ah! me. I am sure I heard the singing of birds, and the faint low of cattle. But I do not know: we come no nearer; and yet I felt its presence in the air. If the mist would only lift, we should see it lying so fair upon the sea, ...

... air, the sun's warmth, the clouds that are described to my understanding spirit, the frequent breaking through the soil of a brook or the expanse of the wind-ruffled lake, the tactual undulation of the hills, which I recall when I am far away from them, the towering trees upon trees as I walk by them, the bearings that I try to keep while others tell me the directions of the various points of the scenery, and you will begin to feel surer of my mental landscape. ...

... criss-crossed in many places by small cracks—like those in sun-scorched mud, except that the cracks were almost black in color. These things caused him no misgivings. But presently, to his consternation, he detected a slight but amazing undulation, an immensely long, immensely slow wave rolling across the dry surface before him. He could hardly believe his eyes—for assuredly nothing could look more like good solid land than that stretch of barren plain. He stopped short, rubbing his eyes ...

... yelping and occasional baying below, the rustling among the limbs, and the undulation caused by the animals leaping upward among the branches; but they ceased to disturb him after a time, and became like the sound of falling water in the ears of the hunter by his camp-fire. It was not long before slumber stole away his senses, and ...

... splashing. Coots and moorhens dived and hid in the reeds. The lesser grebe sank at the sound of the paddle like a stone. A strong northern diver raised a wave as he hurried away under the water, his course marked by the undulation above him. Sedge-birds chirped in the willows; black-headed buntings sat on the trees, and watched him without fear. Bearded titmice were there, clinging to the stalks of the sedges, and long-necked herons rose from the reedy ...

... strength, and the serpent with its vital writhe and deadly reverted bite, are both characteristic of the finest Lombard work. The dog's head is 14th century Gothic—a masterpiece of broad, subtle, easy sculpture, getting expression with every touch, and never losing the least undulation of surface, while it utterly disdains the mere imitation of hair, or attainment ...

... graceful carriage, and it is indeed the poetry of motion, singular as it may appear, when it is remembered that for them to walk abroad is such a rarity. It is not the simple progressive motion alone, but also the harmonious play of features, the coquettish undulation of the face, the exquisite disposition of costume, and the modulation of voice, that engage the beholder and lend a happy charm to every attitude ...

It was a pitiful sight to see the noble mare, almost worn-out with watching and defending herself, while the pack of those sneaking hounds of the wilderness sat or stood around her licking their chops and ...

... passing from Leith to Kinghorn in Scotland, a sudden change of the wind shook the undistended sail, and stopt our boat; from this unusual movement the passengers all vomited except myself. I observed, that the undulation of the ship, and the instability of all visible objects, inclined me strongly to be sick; and this continued or increased, when I closed my eyes, but as often as I bent my attention with energy on the management and mechanism of the ropes and sails, the ...

... Anarajapoora and Dambool. When about a yard apart, each discerned the other and stood still, the spider with his legs slightly bent and his body raised, the cockroach confronting him and directing his antennae with a restless undulation towards his enemy. The spider, by stealthy movements, approached to within a few inches and paused, both parties eyeing each other intently: then suddenly a rush, a scuffle, and both fell to the ground, when ...

Boom! went a third, and a restless undulation swept along the lines. Boom! for a fourth time roared a cannon, and some of the men laughed nervously. Boom! rolled out yet a fifth, and the ranks stood tense and rigid, ...

... been in sight for some time. No doubt my melancholy abstraction accounted for that, and perhaps her presence there was to be explained by a London train which I had listlessly observed come in to the town an hour before. This surmise was confirmed, as presently,—over the brow of a distant undulation in the road, I descried a farmer's gig driven by another young woman. The gig immediately hoisted a handkerchief; so did my pedestrian. At this moment I was within a yard or two of overtaking her. And it was then ...

... contrast with the multitudinous detail, the secular stability, and the vast average of comfort of the Western nations. Life in the East is fierce, short, hazardous, and in extremes. Its elements are few and simple, not exhibiting the long range and undulation of European existence, but rapidly reaching the best and the worst. The rich feed on fruits and game,—the poor on a watermelon's peel. All or nothing is the genius of Oriental life. Favour of the Sultan, or his displeasure, is a question ...

... where the river escapes, except that formed by the gradually increasing throw of the fault. The pool is simply due to the reversal of the natural slope of the river-bed, caused by the formation of a roll or undulation in the ground on the upthrow side of the fault. Its recent origin is evident from the number of dead trees and bamboo clumps still standing ...

... the scene subtended before him. The hill fell abruptly away, and near the bottom glimmered whitewashed cots along a winding road. Still lower down extended marshy common land, laced with twinkling watercourses and dotted with geese; while beyond, in many a rise and fall and verdant undulation, the country rolled onwards through Teign valley and upwards towards the Moor. The expanse seen from this lofty standpoint extended like a mighty map, here revealing a patchwork of multicoloured ...

... on a north course; at 8.5, finding the thicket almost impassable, I ascended a cypress-tree, where a most cheerless view met my sight to the north, east, and west; not a break was visible—nothing but thicket in all directions, with scarcely an undulation of any kind; the view to the north-west was most extensive—nearly twenty miles of thicket could be seen, with a surface as level as the sea. Not considering it prudent to proceed onwards, the thicket being too ...

Tristram, in his account of the ornithology of North Africa in the first volume of the "Ibis," says: "In the desert, where neither trees, brushwood, nor even undulation of the surface afford the slightest protection to its foes, a modification of colour which shall be assimilated to that of the surrounding country is absolutely necessary. Hence without exception the upper plumage of every bird, whether lark, chat, sylvain, ...

... is a mistake to suppose that the normal state of health is represented by a straight horizontal line. Independently of the well-known causes which raise or depress the standard of vitality, there seems to be,—I think I may venture to say there is,—a rhythmic undulation in the flow of the vital force. The "dynamo" which furnishes the working powers of consciousness and action has its annual, its monthly, its diurnal waves, even its momentary ripples, in the current it furnishes. There are greater and ...

When I enter her drawing-room, I usually cause the same sensation that Beelzebub would doubtless produce should he put his foot into one of the drawing-rooms in Paradise. That evening, when I was announced, I saw a certain undulation of heads in a group of young women who were whispering to one another; many curious eyes were fastened upon me, and among these beautiful eyes were two more beautiful than all the others: they were those of my ...

... approached land, Ferragut realized that death was nearer here than on the high sea. The coast rose up before them like an immense wall. Seen from the boat it appeared to cover half the sky. The long oceanic undulation became a ravenous wave upon encountering the outer bulwarks of these barren islands, breaking in the depths of their caves, and forming cascades of foam that rolled around them from top to bottom, raising ...

They watched him for about five minutes, and then lost sight of him over the brow of a slight undulation. Beyond the roughly constructed blockhouses there was not a sign of inhabitants in any direction; the land was rough and uncultivated, there were neither cattle nor sheep to be seen; and if, as they strongly suspected, the blockhouses ...

In the first it is supposed that the universe contains a highly rare elastic substance, which, when put into a state of undulation, produces those effects on our organs of sight which constitute the sensations of vision and other phenomena caused by solar and terrestrial rays. In the second it is conceived that particles are emitted from luminous or heat-making bodies with great velocity, and that they produce their effects ...

Certainly none at all that we can see; and yet these great events so nearly synchronize that even the latest of them seems but a more distant undulation of the same vast swell in the ocean, running along from west to east, from the Tiber to the Tigris. Some great ferment of revolution was then abroad. The overthrew of Nineveh as the capital of the Assyrian empire, the ruin of the dynasty ending in Sardanapalus, and the subsequent ...

Both ranges, Alps and Apennines, are clear to view; and all the silvery lakes are over-canopied and brought into one picture by flame-litten mists. Monte Rosa lifts her crown of peaks above a belt of clouds into light of living fire. ...

Beyond the bush behind which he now crouched all was bare open ground, without a shrub or hillock large enough to conceal the hunter. There was a slight undulation in the ground, however, which enabled him to advance about fifty yards further, by means of lying down quite flat and working himself forward like a serpent. Further than this he could not move without being seen by the antelope, ...

The recently plowed earth, the yellowing roads, the dark woodland, everything was pulsating in weariless undulation. The soil seemed to be clamoring, and its words were the vibrations of the restless little flags. And the thousands of cries, endlessly repeated across the days and nights, were intoning in rhythmic chant the terrible onslaught which this earth ...
