It is not desirable that thevernier should read nearer than one-hundredth of an inch.
In Germany, barometers are sometimes graduated with old French inches and lines,--the vernier generally indicating the tenth of a line.
Passing the eye up the vernier and scale, the second line above 3 is perceived to lie evenly with a line of the scale.
Consequently, when the vernier is set to the mercurial column, the difference shown by the vernier from the tenth on the scale is the hundredths to be added to the inches and tenths of the scale.
It consists of a short scale made to pass along the graduated fixed scale by a sliding motion, or preferably by a rack-and-pinion motion, the vernier being fixed on the rack, which is moved by turning the milled head of the pinion.
The lower edge of the vernier should be brought to the top of the mercury, so as just to shut out the light.
Hence, in household and marine barometers the scale need only be divided to tenths, and the vernier constructed to measure hundredths of an inch.
The vernier enables us to accurately subdivide the tenths into hundredths, and, in first-class instruments, even to thousandths of an inch.
We may now be sure that the line on the circular vernier that cuts the division on the scale is the exact height of the barometer.
If the vernier is adjusted to read upward, the scale should extend to 32 inches, to allow room for the vernier to be set to 31 inches at least.
In those instances where no line on the vernier is found precisely to coincide with a line on the scale, and doubt arises as to which to select from two equally coincident lines, the rule is to take the intermediate 1000th of an inch.
Tube with concave mirror on stand, graduated scale with vernier and lens for reading one-tenth of a degree of rotation.

On the top of d a pointer Z or a vernier is fixed, which laps over the upper edge of the slate disc and points to the graduations.
The pointer or vernier Z is to be brought, by means of the handle g, to the zero point of the large scale on the slate disc.
If the pole is placed farther off, as at F, the rays of light from the pole will take the course of the stroke-and-dot line, and the vernierarm will require to be shifted nearer the zero of the scale.
A is the sight- hole, B is a fixed mirror having one-half silvered and the other half plain; C is a mirror attached to the same pivot as the vernier arm D.
To adjust the box-sextant the smoked glass slide should be drawn over the eyepiece, and then, if the sun is sighted, it should appear as a perfect sphere when the vernier is at zero, in whatever position the sextant may be held.
The thumb-screw farthest from the vernier should then be screwed home, and the other thumb-screw operated to further depress the spring without causing it to lock upon the bar.
Now set the zero of the vernier opposite to the line denoting 49/50 inch on the bar.
But, in any event, the whole of the readings on the vernier may be read, or will be passed through, while it is traversing a division equal to one of the divisions on the scale or rule.
Let it now be noted that, instead of making the lines of division closer together to obtain minute measurements, the same end may be obtained by making the vernier longer.
He was induced by Vernier to hoax the famous traveler, Gaudissart, during a business trip of the latter.
The circle is protected but only onevernier reading to 30 sec.
The prism table can be clamped to any part of the vernier plate.
There is a vernier upon the slide, graduated to hundredths of an inch; a thumb-screw serves to secure the slide at any point on the rod.
A slide is made to play upon it with a vernier scale, graduated to hundredths of an inch.
A vernier is attached to the sliding branch, graduated to hundredths of an inch.
It is provided with a vernier scale graduated to hundredths of an inch.
If the vernier zero is to the right of the zero on the arc, the IE is plus and is to be added to any angle you read to get the correct angle.
But these divisions on the vernier represent minutes and sixths of a minute, or 10 seconds.
The vernier arrow in the sliding limb is set on zero.
Quadrants, octants and quintants work on exactly the same principles as the sextant, except that the divisions on the arc and the vernier differ in number from the sixth divisions on the arc and vernier of the sextant.
If the vernier zero is to the left of the zero on the arc, the IE is minus and it is to be subtracted from any angle you read, to get the correct angle.
To prove whether it is or not, set the vernier on about 60°, and look slantingly through the mirror.
Now on the vernier in the sliding limb, directly under the arc, is the same kind of a division.
Do this by putting the vernier 0 on the arc 0, sliding the limb slowly forward until the top of the lighthouse in the reflected horizon just touches the bottom of the lighthouse in the true horizon.
Set the vernier on zero and look slantingly through the horizon glass.
To read the angle, the zero point on the vernieris used as a starting point.
When graduated to read in thousandths, the true scale is divided into fifty parts and the Vernier into twenty parts.
The Vernier principle can be readily grasped by studying the section of the Vernierscale and true scale shown at Fig.
Each division of theVernier is therefore equal to nineteen-twentieths of one of the true scale.
If the Vernierscale is moved to the right so that the graduations marked "1" shall coincide, it will have moved one-tenth of a division on the scale or one-hundredth of an inch.
This consists essentially of two rules so graduated that the true scale has each inch divided into ten equal parts, the upper or Vernier portion has ten divisions occupying the same space as nine of the divisions of the true scale.
It is evident, therefore, that one of the divisions of the Vernier is equal to nine-tenths of one of those on the true scale.
The Vernieris a device for reading finer divisions on a scale than those into which the scale is divided.
At Left, Special Form of Vernier Caliper for Measuring Gear Teeth; at Right, Micrometer for Accurate Internal Measurements.
If the Vernier be moved so the lines of the first division coincide, it will have moved one-twentieth of one-fiftieth, or .
They were hardly installed before Monsieur Vernier crept softly up through the field and, opening a window, got into the bedroom without noise.
When Madame Vernier heard the name of the lunatic she raised her head and looked at her husband.
I'll go straight to Monsieur Vernier and thank him.
Madame Vernier had related the poor woman's trouble to her husband just before the entrance of Gaudissart, and at the first words of the famous traveller Vernier determined that he should be made to grapple with Margaritis.
The whole town of Vouvray was put in a ferment about the "affair" between Monsieur Vernier and the apostle of Saint-Simonism.
