The muddy waters of the river, when at a low stage, lap the ever crumbling banks that yearly change, yielding to new deflections of the current.

When the commissioners appointed by the two Governments to mark the boundary line came to that point of it which is required to run southerly through the channel which divides the continent from Vancouvers Island, they differed entirely in their opinions, not only concerning the true point of deflection from the forty-ninth parallel, but also as to the channel intended to be designated in the treaty.

The following table will show, by comparison of the versed sines of very small angles, the deflection in a given circle varying as the square of the speed, when we penetrate to them, so nearly that the error is not disclosed at the fifteenth place of decimals.

But taking the average of the best series of observations, the deflection at the sun's limb is found to be 1.98'', with a probable error of about 6 per cent., whereas the deflection calculated by Einstein's theory should be 1.75''.

In this instrument, momentum and inertia are almost wholly avoided by the use of a needle weighing only one and a half grains, combined with a mirror reflecting a ray of light, which indicates deflections with great accuracy.

A rapid deflection increases the amount of the deflection as well as the amount of the strain, as is seen in the cylinder cover of a Cornish pumping engine, into which the steam is suddenly admitted, and in which the momentum of the particles of the metal put into motion increases the deflection to an extent such as the mere pressure of the steam could not produce. 74.

This preponderating repulsive effect may be utilized or may show its presence by producing movement or pressure in a given direction, by producing angular deflection as of a pivoted body, or by producing continuous rotation with a properly organized structure.

It has been found, experimentally, that a cast-iron bar, deflected by a revolving cam to only half the extent due to its breaking weight, will in no case withstand 900 successive deflections; but, if bent by the cam to only one third of its ultimate deflection, it will withstand 100,000 deflections without visible injury.

Owing to the bad weather I could get no observation for azimuth, and had to produce the survey from Pyramid Island to Taiya Inlet by reading the angles of deflection between the courses.

The latter instrument consisted of a spring whose deflection by a given weight upon the equator had been very carefully tested.

Variations in the humidity of the surrounding air influence the deflection of dry wood under dead load, and increased deflections during damp weather are cumulative and not recovered by subsequent drying.

The lateral bending of a column produces a combination of bending with compressive stress over the section, the compressive stress being maximum at the section of greatest deflection on the concave side.
