This framework is provided with guides on which the platform, whilst preserving its horizontality, is V the observer has to follow the eye-end in a comparatively small circle; another good point is the flattening of the cast-iron centrepiece of the tube so that the flange of the declination axis is attached as near to the axis of the telescope tube as is consistent with free passage of the cone of rays from the object-glass.

The observer at the eye-end can also read off the hour and declination circles and communicate quick or slow motions, to the telescope both in right ascension and declination by conveniently Pulkovo, placed handles.

Other water engines, similarly connected, with keys at the observer's hands, rotate the dome and perform the quick motions in right ascension and declination.

The jet should be situated between the sparks and the eye, and the observation is facilitated by a piece of ground glass held a little beyond the jet, sO as to diffuse the light; or the shadow of the jet may be received on the ground glass, which is then held as close as possible on the side towards the observer.

Huntington's inhabitants were mostly strong patriots, notably Ebenezer Prime (1700-1779), pastor of the First Presbyterian Church, which the British used as a barracks, and his son Benjamin Young Prime (1733-1791), a physician, linguist and patriot poet, who was the father of Samuel Irenaeus Prime (1812-1885), editor of the New York Observer.

The discovery of a single fossil creature in a geological stratum of a wrong period, the detection of a single anatomical or physiological fact irreconcilable with origin by descent with modification, would have been destructive of the theory and would have made the reputation of the observer.

For other areas we have often no description of the procedure at all, but merely the briefest outline of the actual process of slaughter, and we are ignorant whether the form of the rite is in reality simple (either from a loss of primitive elements or from never having advanced beyond the stage at which we find it), or whether the absence of detail is due to the inattention or lack of interest of the observer.

They are formed by parallel rays of light emanating from two sources, as, for example, the sun and its image in a sheet of water, which is situated between the observer and the sun.

A shrewd observer at the time pronounced him indispensable.

The monthly reviews include the Christian Observer (1802-1857), conducted by members of the established church upon evangelical principles, with Zachary Macaulay as the first editor; Monthlies.

Among those which also include political and social topics, and are more particularly dealt with under Newspapers, may be mentioned, the Examiner (1808-1881), the Spectator (1828), the Saturday Review (1855), the Scots or National Observer (1888-1897), Outlook (1898), Pilot (1900-1903), and Speaker (1890), which became the Nation.

This wheel is acted on by a tangent screw whose bearings are attached to the cradle; the screw is turned by means of a handle supported by bearings attached to the cradle, and coming within convenient reach of the observer's hand.

With similar bevel-gear and rods the tangent screw is connected to the hand-wheel, 79, by which the observer communicates the fourth or slowest motion in position angle.

Thus the scales, the positionand declination-circles, the field of view, the heads of all the micrometer-microscopes, the focusing scale, &c., are read without the aid of a hand-lamp and with an amount of illumination that can be regulated at the observer's pleasure.

It enables the observer to compare any division-interval on one half of either scale with any corresponding interval on the other scale.

Of course, for many purposes, mean conditions may be adopted and mean scale-values be found which are applicable with considerable pre cision to small angles or to comparatively crude observations of large distances; but the highest refinement is lost unless means are provided for determining the scale-value for each observer at each epoch of observation.

Gill introduced a powerful auxiliary to the accuracy of heliometer measures in the shape of a reversing prism placed in front of the eye-piece, between the latter and the observer's eye.

If measures are made by placing the image of a star in the centre of the disk of a planet, the observer may have a tendency to do so systematically in error from some acquired habit or from natural astigmatism of the eye.

Practically the difficulty of making these diaphragms for the different powers of the exact required equality is insuperable; but, if the observer is content to lose a certain amount of light, we see no reason why they may not readily be made slightly less.

How hard it must have been to obtain a footing there while he was a mere student and observer!

An obvi us method of determining the velocity of sound in air consists in starting some sound, say by firing a gun, and stationing an observer at some measured distance from the gun.

The observer measures by a clock or chronometer the time elapsing between the receipt of the flash, which passes practically instantaneously, and the receipt of the report.

It is different, too, for different senses with the same observer, and different even for the same sense when the external stimuli differ in intensity.

An observer with his ear to the tube noted the interval between the arrival of flash and sound.

In the first case the waves are more likely to reach and be perceived by an observer level with the source, while in the second case they may go over his head and not be heard at all.

As these " secondary waves " return to S their distance apart is nearly equal to twice the distance between the rails, and the observer then hears a note of wave-length nearly 2EF.

But if an observer is stationed at S' the waves will be about half as far apart and will reach him with nearly twice the frequency, so that he hears a note about an octave higher.

If both forks vibrate, an observer looking through the microscope sees the bright point describing Lissajous figures.

A very noticeable illustration of the alteration of pitch by motion occurs when a whistling locomotive moves rapidly past an observer.

An observer in the plane of the motion can easily hear a change in the pitch as the pitch-pipe moves to and from him.

But there is no doubt that it is very difficult to detect the summation tone by the ear, and many workers have doubted the possibility, notwithstanding the evidence of such an observer as Helmholtz.

If the surrounding aether is thereby disturbed, the waves of light arriving from the stars will partake of its movement; the ascertained phenomena of the astronomical aberration of light show that the rays travel to the observer, across this disturbed aether near the earth, in straight lines.
