If we restrict ourselves to this set of symbols we can **uniquely** pass from a product of real coefficients to the symbolic representations of such product, but we cannot, **uniquely**, from the symbols recover the real form, This is clear because we can write n-1 n-2 2 2n-3 3 a1a2 =a l a 2, a 1 a 2 = a 1 a2 while the same product of umbrae arises from n n-3 3 2n-3 3 aoa 3 = a l .a a 2 = a a 2 .

The volcanic d'Entrecasteaux Islands are mostly larger, more elevated (the highest being 8000 ft.), and stand in deeper water than the Louisiade group. To the east of Kiriwina (Trobriand) lies a small group of **uniquely** formed islets, each of which is completely surrounded by a steep forest-clad marginal rampart of coral 300 to 400 ft.

His principal architect was Domenico Fontana, who, in conjunction with Guglielmo della Porta, completed the **uniquely** beautiful cupola of St Peter's which had already been designed by Michelangelo in a detailed model.

The pharmacopoeial mixture is best avoided, being almost **uniquely** nauseous.

Thus a fdrce can be **uniquely** resolved into two components acting in two assigned directions in the same plane with it by an inversion of the parallelogram construction of fig.

The same holds for the four points B, C, D, E and so on; but since a parabola is **uniquely** determined by the direction of its axis and by three points on the curve, the successive parabolas ABCD, BCDE, CDEF ...

It follows that the single resultant to which the system in general reduces is **uniquely** determinate, i.e.

When a plane frame which is just rigid is subject to a given system of equilibrating extraneous forces (in its own plane) acting on the joints, the stresses in the bars are in general **uniquely** determinate.

We have seen that the stresses produced by an equilibrating system of extraneous forces in a frame which is just rigid, according to the criterion of 6, are in general **uniquely** determinate; in particular, when there are no extraneous forces the bars are in general free from stress.

Any quantity, commensurable or incommensurable, can be expressed **uniquely** as a simple continued fraction, terminating in the case of a commensurable quantity, non-terminating in the case of an incommensurable quantity.

Jobs done by people will be only the ones that require **uniquely** human capabilities to do.
