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.
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.
In the typical newts (Molge) of Europe, the males are adorned during the breeding season with bright colours and crests or other ornamental dermal appendages, and, resorting to the water, they engage in a lengthy courtship accompanied by lively evolutions around the females, near which they deposit their spermatozoa in bundles on a gelatinous mass, the spermatophore, probably secreted by the cloacal gland.
The marginal crests of this mountain tableland, together with its upper surface, are known locally as " Tiers," and have a very commanding aspect in the neighbourhood of Longford, Westbury, Deloraine and Chudleigh.
Of Cephalonia, forming with it, Leucas and Ithaca a crescent-shaped insular group, which represents the crests of a submerged limestone ridge facing the Gulf of Patras.
The villages are substantially built of stone, often picturesquely situated on the spurs and crests of the hills, the houses clustering round the dars or towers which dominate the cultivated slopes and valleys.
Beat down for me the crests of the tide-rip; let the tide-rip settle down away from me, beat it down level that it may sink and roll away, and I may come to a quiet landing-place."
The hills of the north-east are mainly the crests of lavaplateaux, which carry the mind towards Skye and the volcanic province of the Faeroe Islands.
The interior villages are frequently situated on hill crests, or on top of steepfaced rocks as difficult of access as possible, whence a clear view all round can be had.
The main roads laid out as arteries of intercommunication by the Romans, suffered to fall into neglect, and revived in the coaching days of the beginning of the 19th century, fell into a second period of comparative neglect when the railway system was completed; but they have recovered a very large share of their old importance in consequence of the development of motortraffic. Following the Roman roads, the high roads of the Eastern Division very frequently run along the crests of ridges or escarpments; but in the Western Division they are, as a rule, forced by the more commanding relief of the country to keep to the river valleys and cross the rougher districts through the dales and passes.
A, b, Crests of the wave; c, d, e, up strokes; x, x, down strokes; f, point corresponding to the anterior margin of the wing, and forming a centre for the downward rotation of the wing (a, g); g, point corresponding to the posterior margin of the wing, and forming a centre for the upward rotation of the wing (d, f).
29 shows how in progressive flight the wing and the body describe waved tracks, - the crests of the waves made by the wing (a, c, e, g, i) being placed opposite the crests of the waves made by the body I, 2, 3, 4, 5).
- When a series of waves is propagated on the surface of a liquid, the surface-tension has the effect of increasing the pressure at the crests of the waves and diminishing it in the troughs.
