The principles of the support, as a whole, of a structure resting on the land, are so far identical with those which regulate the equilibrium and stability of the several parts of that structure that the oni principle which seems to require special mention here is one whic comprehends in one statement the power both of liquids and of loose earth to support structures.

The power of resisting displacement constitutes stability, the power of each piece to resist disfigurement is its stiffness; and its power to resist breaking, its strength.

Stability of Position, and Stability of Frictio-n.The resistances at the several joints having been determined by the principles set forth in 6, 7, 8, 9 and 10, not only under the ordinary load of the structure, but under all the variations to which the load is subject as to amount and distribution, the joints are now to be placed and shaped so that the pieces shall not suffer relative displacement under any of those loads.

Safety against displacement by turning is called stability of position; safety against displacement by sliding, stability of friction.

Condition of Stability of Position.If the materials of a structure were infinitely stiff and strong, stability of position at any joint would be insured simply by making the centre of resistance fall within the joint under all possible variations of load.

That least distance is called by Moseley the modulus of stability.

If the joint be provided either with projections and recesses, such as murtises and tenons, or with fastenings, such as pins or bolts, so as to resist displacement by sliding, the question of the utmost amount of the tangential resistance CQ which it is capable of exerting depends on the strength of such projections, recesses, or fastenings; and belongs to the subject of strength, and not to that of stability.

Stability of Friction in Earth.The grains of a mass of loosi earth are to be regarded as so many separate pieces abutting agains each other at joints in all possible positions, and depending for thei stability on friction.

The condition of stability is that this obliquity shall not exceed the angle of repose of the earth.

The consequences of this principle are developed in a paper, On the Stability of Loose Earth, already cited in 2.

The Gironde red wines have sufficient body and alcohol to ensure stability without being heavy or fiery.

The vinification of the Burgundy wines takes place in cuves of 500 to 2000 gallons capacity, and it has for very many years been the common practice in vintages in which the must is deficient in saccharine to ensure the stability of the wine by the addition of some sugar in the cuve.

The practice of sugaring has ensured greater stability and keeping power to the wines, which formerly were frequently irregular in character and difficult to preserve.

The wines, moreover, of Algeria are on the whole of decidedly fair quality, possessing body and strength and also stability.

The finer wines possess great breed and distinction, coupled with a very fine and pronounced bouquet, and in addition they are endowed with the - in the case of lighter wines - rare quality of stability.

They display many of the features characteristic of southern wines, showing either an excessive vinosity coupled with a somewhat crude bouquet, or where the alcoholic strength is not high, a decided lack of stability.

The limiting conditions of the stability of these figures have been studied both mathematically and experimentally.

But the surface-tension, acting on a cylindric column of liquid whose length exceeds the limit of stability, begins to produce enlargements and contractions in the stream as soon as the liquid has left the orifice, and these inequalities in the figure of the column go on increasing till it is broken up into elongated fragments.

Let us conceive an infinitely long circular cylinder of liquid, at rest (a motion common to every part of the fluid is necessarily without influence upon the stability, and may therefore be left out of account for convenience of conception and expression), and inquire under what circumstances it is stable or unstable, for small displacements, symmetrical about the axis of figure.

The capillary tension endeavours to contract the surface of the fluid; so that the stability, or instability, of the cylindrical form of equilibrium depends upon whether the surface (enclosing a given volume) be greater or less respectively after the displacement than before.

The condition of stability of a catenoid is therefore that the tangents at the extremities of its generating catenary must intersect before they reach the directrix.

We shall next consider the limiting conditions of stability of the horizontal surface which separates a heavier fluid above from a lighter fluid below.

The equilibrium of the fluids would now be unstable if it were not for the tension of the surface which separates them, and which, when the orifice of the vessel is not too large, continues to preserve the stability of the equilibrium.

It is to be noted that in the case of bacteria we can only judge of organisms being of different species by the stability of the characters which distinguish them, and numerous examples might be given where their characters become modified by comparatively slight change in their environment.

During his long term of office he abolished the grist tax, extended the suffrage, completed the railway system, aided Mancini in forming the Triple Alliance, and initiated colonial policy by the occupation of Massawa; but, at the same time, he vastly increased indirect taxation, corrupted and destroyed the fibre of parliamentary parties, and, by extravagance in public works, impaired the stability of Italian finance.

These models flew in a haphazard sort of a way, it being found exceedingly difficult to confer on them the necessary degree of stability fore and aft and laterally.

They depended mainly on the utilization of natural air currents, trusting for stability and balance to movements in their own bodies, or in portions of their machines which they could control.
