If the actual crests of the excursions had been measured the figures in the second line would have been even larger.
When the attempt was made to mark this boundary the commissioners were unable to agree on a line across the Puna de Atacama in the north, where parallel ranges enclosing a high arid plateau without any clearly defined drainage to the Atlantic or Pacific, gave an opportunity for conflicting claims. In the south the broken character of the Cordillera, pierced in places by large rivers flowing into the Pacific and having their upper drainage basins on the eastern side of the line of highest crests, gave rise to unforeseen and very difficult questions.
Rn, covers eastern France from the Mediterranean to the Vosges, from the Cvennes and the Plateau de Langres to the crests of the Jura and the Alps.
Roots are often flattened, twisted and otherwise distorted by mechanical obstacles; stems by excess of food in rich soils, the attacks of minute parasites, overgrowth by climbing plants, &c. Leaves are especially apt to vary, and although the formation of crests, pitchers, puckers, &c., must be put down to the results of abnormal development, it is often difficult to draw the line between teratological and merely varietal phenomena.
Plateaus are finally crowned by the wrinkled crests which form its two modern mountain systems. The surface of each of our ocean floors exactly resembles that of a continent turned upside down.
The humerus with its crests, ridges and processes, presents so many modifications characteristic of the various groups of birds, that its configuration alone is not only of considerable taxonomic value but that almost any genus, excepting, of course, those of Passeres, can be " spotted " by a close examination and comparison of this bone.
428-429) distinguishes the Leleges (q.v.) from the Carians, to whom is ascribed the invention of helmet-crests, coats of arms, and shield handles.
Many of the neighbouring mountain ridges have uniform crests, but a greater number terminate in numerous peaks, some sharp, rugged and rocky, but more of them rounded domes.
The transverse water-parting between the Black Sea and the Caspian begins on the south side of the main range of the Caucasus, at Mount Zikara (12,560 ft.), a little south-west of Kasbek, and runs south-west along the sinuous crests of the Racha, Suram or Meskes (3000-5000 ft.), Vakhan (10,000-11,000 ft.), Arzyan (700(3.- 10,000 ft.), and its continuation the Soganluk, thus linking the Caucasus ranges with those of the Armenian highlands.
The cheek-teeth are short-crowned, generally with no cement, the upper molars having a W-shaped outer wall, from which proceed two oblique transverse crests, while the lower ones carry two crescents.
In the upper molars the two outer columns or tubercles of the primitive tubercular molar coalesce to form an outer wall, from which proceed two crescentic transverse crests, the connexion between the crests and the wall being slight or imperfect, and the crests themselves sometimes tubercular.
Outer walls of upper cheek-teeth W-shaped, and transverse crests oblique.
The upper cheek-teeth are short-crowned and without cement, and show distinct traces of the primitive tubercles; the two outer columns form a more or less complete external wall, connected with the inner ones by a pair of nearly straight transverse crests; and the premolars are originally simpler than the molars.
The first lower premolar compressed in front; the others composed of a single pair of transverse crests, with a small anterior and posterior basal ridge.
Below the mountain crests, where only the hardiest lichens and mosses can survive, comes a belt of large timber, including many giant trees, 200 ft.
When the rocks are concealed by detrital material he looks for outcroppings on steep hillsides, on the crests of hills or ridges, in the beds of streams, in landslides, in the roots of overturned trees, and in wells, quarries, roadcuttings and other excavations.
It lies amidst a wild, inaccessible region of snowbound crests, and is certainly nowhere less than 15,000 ft.
There are few passes across the southern section of the Hindu Kush (and this section is, from the politico-geographical point of view, more important to India than the whole Himalayan system) which have not to surmount a succession of crests or ridges as they cross from Afghan Turkestan to Afghanistan.
The true use of engraving is to add interest to vessels by means of coats of arms, crests, monograms, inscriptions and graceful outlines.
Sometimes, especially at early dawn, there is a musical noise in the desert, like the sound of distant drums, which is caused by the eddying of grains of sand in the heated atmosphere, on the crests of the medanos.
Along the western side of northern Anti-Lebanon stretches the Khasha'a, a rough red region lined with juniper trees, a succession of the hardest limestone crests and ridges, bristling with bare rock and crag that shelter tufts of vegetation, and are divided by a succession of grassy ravines.
The soft shales or clays of the hills bounding the valley render these hills especially subject to the action of denudation, and the result, in rounded slopes and easily accessible crests, determines the nature of the easy tracks and passes which intersect them.
The cheek teeth are short crowned (brachyodont), with the tubercles more or less completely fused into transverse ridges, or cross-crests (lophodont type); and the total number of teeth is in one case the typical 44, but in another is reduced below this.
In the southern half of the state the height of the crests of the divides is very uniform.
Io) represents the displacement curve of a train of waves, will represent the pressure excess and particle velocity, and from (II) we see that while the nodal conditions of b, with Co' and u=o, travel with velocity 1/(E/p), the crests exceed that velocity by 1(7 + i)u, and the hollows fall short of it by 1(7 + I)u, with the result that the fronts of the pressure waves become steeper and steeper, and the train b changes into something like c. If the steepness gets very great our investigation ceases to apply, and neither experiment nor theory has yet shown what happens.
Side, their outer crests being some 4000 yds.
But although the crests of its component ranges reach altitudes of 21,500 to 22,000 ft., they are not as a rule overtopped by individual peaks of commanding and towering elevation, as the Himalayas are, but run on the whole tolerably uniform and relatively at little greater altitude than the lofty valleys which separate them one from another.
Altogether this western extremity of the Kuen-lun system is a very rugged mountainous region, a consequence partly of the intricacy of the flanking ranges and spurs, partly of the powerful lateral compression to which they have been subjected, and partly of the great and abrupt differences in vertical elevation between the crests of the ranges and the bottoms of the deep, narrow, rugged glens between them.
As a rule the crests of the ranges are worn down by aerial denudation and have the general appearance of rounded domes.
But there exists a striking difference between the crests of the Astin-tagh and those of the ranges which give rise to the gigantic ridge and furrow arrangement on the Tibetan plateau.
Of great length, the Arka-tagh, which is a mountain-system rather than a range, varies greatly in configuration in different parts, sometimes exhibiting a sharply defined main crest, with several lower flanking ranges, and sometimes consisting of numerous parallel crests of nearly uniform altitude.
The crests of the ranges lie comparatively little higher than the valleys which separate them, the altitudes in the latter running at 14,940 to 16,700 ft., if not higher, and being only 500 to moo ft.
Lower than the crests of the accompanying ranges.
The view that meets the eye southwards from the heights of the Kalta-alaghan is the picture of a chaos of mountain chains, ridges, crests, peaks, spurs, detached masses, in fact, montane conformations of every possible description and in every possible arrangement.
Besides these large crested species, there are several smaller species without crests in north-east India, and the Malay region from Nepal to Borneo.
Farther west the serrated crests of the Blue Ridge overlook the Greater Appalachian Valley, here 73 m.
Of the southern shores of the river San Juan and of Lake Nicaragua, terminates at Salinas Bay on the Pacific; its southern frontier skirts the valley of the Sixola or Tiliri, strikes south-east along the crests of the Talamanca Mountains as far as 9° N., and then turns sharply south, ending in Burica Point.
Sides, sharp crests and gently sloping S.E.
The crests of the higher ridges in the central province are delightfully cool in summer, but the adjacent valleys are subject to excessive heat in summer and severe cold in winter.
They wore brazen helmets with purple crests, and rough-haired black cloaks, in which they slept on the bare ground.
Closer examination, however, shows that if the prevailing slopes are not more than a few inches in the mile, yet they do exist, and scientific irrigation requires that the canals should be taken along the crests and drains along the hollows.
The rocks project in innumerable bosses and crags, which roughen the sides and crests of the ridges.
Among these high grounds also the gradual narrowing of ridges into sharp, narrow, knife-edged crests and the lowering of these into cols or passes can be admirably studied.
A treaty was entered into with his son, Yakub Khan, at Gandamak, by which the British frontier was advanced to the crests or farther sides of the passes and a British officer was admitted to reside at Kabul.
Broad from the crests of the inclosing mountain ranges (or 5-10 m.
The city is built upon a sloping plain at the base of two high mountains, La Guadeloupe and Montserrato, upon whose crests stand two imposing churches.
Teeth of Skew-Bevel Wheels.The crests of the teeth of a skew-bevel wheel are parallel to the generating straight line of the hyperboloidal pitch-surface; and the transverse sections of the teeth at a given pitch-circle are similar to those of the teeth of a bevelwheel whose pitch surface is a cone touching the hyperboloidal surface at the given circle.
Besides these excavated monuments, the Stadion; the enceinte of fortifications erected by Lysimachus, which runs from the tower called the "Prison of St Paul" and right along the crests of the Bulbul (Prion) and Panajir hills; the round monument miscalled the "Tomb of St Luke"; and the Opistholeprian gymnasium near the Magnesian gate, are worthy of attention.
There is ample proof throughout the country of alterations of level within recent geologic periods; and there have even been compressions, resulting in a relative rise of the ground, over the crests of anticlinal folds, within historic record.
Recent investigations show that all the chief rivers of Nepal flowing southwards to the Tarai take their rise north of the line of highest crests, the " main range " of the Himalaya; and that some of them drain long lateral high-level valleys enclosed between minor ridges whose strike is parallel to the axis of the Himalaya and, occasionally, almost at right angles to the course of the main drainage channels breaking down to the plains.
