In Entre Rios, decreases to 27 in.
As the tableland runs northward it decreases both in height and width, until it narrows to a few miles only, with an elevation of scarcely 1500 ft.; under the name of the Blue Mountains the plateau widens again and increases in altitude, the chief peaks being Mount Clarence(4000 ft.), Mount Victoria (3525 ft.), and Mount Hay (3270 ft.).
The Dividing Range decreases north of the Blue Mountains, until as a mere ridge it divides the waters of the coastal rivers from those flowing to the Darling.
In both cases the amplitude of the oscillations decreases more or less rapidly.
The former presents an intimate mixture of boulders brought from Finland and Olonets (with an addition of local boulders) with small gravel, coarse sand and the finest glacial mud, - the whole bearing no trace of ever having been washed up and sorted by water in motion, except in subordinate layers of glacial sand and gravel; the size of the boulders decreases on the whole from N.
It is not economical to force the boiler to work at too high a rate, because it has been practically demonstrated that the boiler efficiency decreases after a certain point, as the rate of combustion increases.
In Hungary and Russia a zone-tariff system is in operation, whereby the charge per mile decreases progressively with the length of the journey, the traveller paying according to the number of zones he has passed through and not simply according to the distance traversed.
During the winter the normal temperature decreases quite steadily from south to north; thus the mean temperature in January at Biloxi is 51° F., at Meridian, in the east central part, it is 46° F., and at Pontotoc it is 43° F.
Per mile, while that of the Sandusky decreases from about 7 ft.
Let us suppose that the light is incident perpendicularly, and that the grating interval increases from the centre towards that edge which lies nearest to the spectrum under observation, and decreases towards the hinder edge.
As the point P is more and more deeply immersed in the shadow, the illumination continuously decreases, and that without limit.
The use of such explosives decreases to some extent the danger from dust explosions; but experiment shows that no efficient explosive is absolutely safe, if used in excessive quantity, or in an improper manner.
In some mines dust seems to have but little effect on the health of the miners; indeed it is even claimed by some that coal dust decreases the mortality from phthisis.
Among these the softness decreases in about the following order: lead, pure silver, pure gold, tin, copper, aluminium, platinum, pure iron.
On descending into the substratum the finer material decreases and more stones are met with; farther down are seen larger fragments of unaltered rock closely packed, and this brash or rubble grades insensibly into the unbroken rock below.
Later the nitrogen-content of the nodule decreases, most of the organisms, which are largely composed of proteid material, becoming digested and transformed into soluble nitrogenous compounds which are conducted to the developing roots and seeds.
The oxygen, however, decreases with the depth, while the carbon dioxide increases.
Or more; farther east the elevation of the highland decreases steadily, and in the Hadramut, north of Mukalla, does not much exceed Hadramut.
The number of species and individuals steadily decreases in the cooler temperate zones, whilst it reaches its maximum in the tropics.
Sanitation decreases the death-rate, religion keeps up the birth-rate.
In the region of Galveston, along the northern section of the coast, where southerly or south-easterly winds from the Gulf prevail throughout the year, the climate is warm, moist and equable, but the moisture decreases westward and south-westward, and the equability, partly because of northerly winds during the winter months, decreases in all directions inland.
The mean annual temperature decreases to the north-westward with an increase of both altitude and latitude, and ranges from 73° F.
The mean temperature for January decreases from 59° at Brownsville, at the southern extremity of the state, to 36° at Amarillo in the Panhandle.
The average annual rainfall decreases quite regularly westward and south-westward from 47.6 in.
Its elevation decreases toward the N.
Its maximum solubility in water is at 34 0; above that temperature it ceases to exist in the solution as a decahydrate, but changes to the anhydrous salt, the solubility of which decreases with rise of temperature.
But as the air is withdrawn by the pump the sound decreases, and when the exhaustion is high the.
In that short time the displacement at H decreases from HP to HP' or by PP'.
At L the displacement backward decreases, or the motion is forward FIG.
But if the wind is against the sound the velocity of a point of the wave front is the normal velocity-the wind velocity at the point, and so decreases as we rise.
In the one, the energy of vibration of the source is measured, and the rate at which that energy decreases is observed.
As the carbon-content increases the welding power naturally decreases rapidly, because of the rapid fall of the " solidus curve at which solidification is complete (Aa of fig.
The reason for its birth, of course, is that the solubility of carbon in austenite progressively decreases as the temperature falls, from about 2.2% at 1130° (a), to 0.90% at 690° (Ar 1), as shown by the line aS, with the consequence that the austenite keeps rejecting in the form of this pro-eutectoid cementite all carbon in excess of its saturation-point for the existing temperature.
The electromotive force is practically constant no matter what the velocity of the disks, but according to some observers the internal resistance decreases as the velocity increases.
In this particular case the solubility decreases with rise of temperature.
The mean annual temperature decreases to the north-westward on the Alleghany plateau, but on the Erie plain, in the extreme north-west, Lake Erie exerts its moderating influence, the mean temperature rises, and extremes shorten.
The mean annual temperature in the south-east province is about 52° F.; it decreases to 50° in the central province and to 47° or less in some of the north-west counties of the Alleghany plateau, but rises to 49° on the shore of Lake Erie.
The age of the several inhabited islands, or at least the time since the last eruptions on them, decreases from W.
In the eastern forest region the number of species decreases somewhat from south to north, but the entire region differs from the densely forested region of the Pacific Coast Transition zone in that it is essentially a region of deciduous or hardwood forests, while the latter is essentially one of coniferous trees; it differs from the forested region of the Rocky Mountains in that the latter is not only essentially a region of coniferous trees, but one where the forests do not by any means occupy the whole area, neither do they approach in density or economic importance those of the eastern division of the country.
The decades 1840-1850,1880-1890and1860-1870have shown much the ~reatest decreases in the percentage of children; and some have attri~uted this to the alleged heavier immigration of foreigners (largely adults)- in the case of the two former decades, and the effects of the Civil War in the third.
So also the three decades immediately succeeding the above showed minimum decreases; and this has been attributed to a supposed greater birth-rate among the immiggants.
The piedmont belt may be described as a maturely dissected peneplain over much of its extent; it is indeed one of the best examples of that class of forms. Its uplands are of fairly accordant altitude, which gradually decreases from 500 to 1000 ft.
