For such purposes, as also for use as mirrors, masks and labrets, it was extensively employed, under the name, of itztli, by the ancient Mexicans, who quarried it at the Cerro de las Navajas, or "Hill of Knives," near Timapan.

During the 16th and 17th centuries Venice exported a prodigious quantity of mirrors, but France and England gradually acquired knowledge and skill in the art, and in 1772 only one glass-house at Murano continued to make mirrors.

He also made with great taste and skill large lustres and mirrors with frames of glass ornamented either in intaglio or with foliage of various colours.

During the protectorate all patent rights virtually lapsed, and mirrors and drinking-glasses were once more imported from Venice.

The chronicle of the Sinhalese kings, the Mahavamsa, however, asserts that mirrors of glittering glass were carried in procession in 306 B.C., and beads like gems, and windows with ornaments like jewels, are also mentioned at about the same date.

Dumas, who regarded them as hydrates of olefiant gas (ethylene); on the other they yielded chloroform, chloral and aldehyde, as well as other compounds of less general interest, and also the method of forming mirrors by depositing silver from a slightly ammoniacal solution by acet aldehyde.

He also had some knowledge of the properties of concave and convex lenses and mirrors in forming images.

His arrangement of concave and plane mirrors, by which the realistic images of objects inside the house or in the street could be rendered visible though intangible, there alluded to, may apply to a camera on Cardan's principle or to a method of aerial projection by means of concave mirrors, which Bacon was quite familiar with, and indeed was known long before his time.

Tin amalgam is used for "silvering" mirrors, gold and silver amalgam in gilding and silvering, cadmium and copper amalgam in dentistry, and an amalgam of zinc and tin for the rubbers of electrical machines; the zinc plates of electric batteries are amalgamated in order to reduce polarization.

Experiments may be made with plane and curved mirrors to verify these laws, but it is necessary to use short waves, in order to diminish diffraction effects.

For this purpose four vertical mirrors are arranged round the vertical sides of a cube which is rapidly revolved about a vertical axis.

The flame appears to lengthen, but if the reflection is viewed in a vertical mirror revolving about a vertical axis or in Koenig's cube of mirrors, it is seen that the flame is really intermittent, jumping up and down once with each vibration, sometimes apparently going within the jet tube at its lowest point.

If one prong of each fork be furnished with a small plain mirror, and a beam of light from a luminous point be reflected successively by the two mirrors, so as to form an image on a distinct screen, when one fork alone is put in vibration, the image will move on the screen and be seen as a line of a certain length.

The Tatar zodiac is not unfrequently found engraven on Chinese mirrors in polished bronze or steel of the 7th century, and figured on the " plateau of the twelve hours "' 5 " Orat.

His name is best known for the improvements he effected in the mirrors of reflecting telescopes and especially in the construction of the microscope.

Essentially it consists in an optical system of lenses and mirrors, or mirrors alone, the upper part of which projects from cover, or from the deck of a submarine, while the observer looks into the lower end, receiving an image of the surrounding country or sea by reflection down a tube.

The use of reflecting mirrors for the purpose of observing from cover is no novelty, and during the trench warfare of the Crimean War 1854-5 a device was patented which scarcely differs from the simple mirror periscope of the World War.

But in order to obtain an adequate field of view, the mirrors, and therefore the box, had to be made somewhat large, and in the close-quarters conditions of trench warfare even the few inches by which they projected over the parapet or ether cover made them sufficiently obvious to draw fire.

From the Fijian and Andaman islander who exhibits abject terror at seeing himself in a glass or in water, to the English or European peasant who covers up the mirrors or turns them to the wall, upon a death occurring, lest an inmate of the house should see his own face and have his own speedy demise thus prognosticated, the idea holds its ground.

The movements of the apparatus, which when complete should consist of two similar pendulums in planes at right angles to each other, are recorded by means of a beam of light, which, after reflection from the mirror or mirrors, passes through a cylindrical lens and is focussed upon a moving surface of photographic paper.

A large number of utensils, articles of furniture and the like were placed in the burial-chamber for the use of the deadjars, weapons, mirrors, and even chairs, musical instruments and wigs.

Many bronze mirrors were found.

A cemetery at Locri yielded large numbers of poor Greek vases, and some exceptionally fine bronze mirrors.

A few mirrors and some Greek vases were found in Etruria at Vignanello in 1913, and from an Etruscan tomb at Todi in 1915 there were obtained some bronzes and more than 70 redfigure vases.

James Gregory, in his Optica Promota (1663), discusses the forms of images and objects produced by lenses and mirrors, and shows that when the surfaces of the lenses or mirrors are portions of spheres the images are curves concave towards the objective, but if the curves of the surfaces are conic sections the spherical aberration is corrected.

A A and B B are concave mirrors having a common axis and their concavities facing each other.

The practical difficulty of constructing Gregorian telescopes of good defining quality is very considerable, because if spherical mirrors are employed their aberrations tend to increase each other, and it is extremely difficult to give a true elliptic figure to the necessarily deep concavity of the small speculum.

The magnifying power of the telescope is = Ff /ex, where F and f are respectively the focal lengths of the large and the small mirror, e the focal length of the eye-piece, and x the distance between the principal foci of the two mirrors (=Ff in the diagram) when the instrument is in adjustment for viewing distant objects.

One of Short's mirrors, made about 1760 or 1770, of 6-in.

Silvered mirrors have also some advantage in light grasp over those of speculum metal, though, aperture for aperture, the former are inferior to the modern object-glass.

There must be a certain loss of light from two, additional reflections; but that could be tolerated for the sake of other advantages, provided that the mirrors could be made sufficiently perfect \ optical planes.

By making the mirrors of silvered glass, one-fourth of their diameter in thickness, the Henrys have not only `.

The instrument in some respects resembles the equatorial equatorial coude of Loewy, but instead of two mirrors Camp there is only one.

In those of type E the eye-piece has a fixed position and the observer may even occupy a room maintained at uniform temperature, but he must submit to a certain loss of light from one or more reflecting surfaces, and from possible loss of definition from optical imperfection or flexure of the mirror or mirrors.

The mirrors of Lindemann's equatorial coude reflecting light downwards upon the mirror R would furnish an ideal siderostat for stellar spectroscopy in conjunction with a fixed horizontal telescope.

It is one of the principal seats of the glass industry in Indiana - plate glass, lamp chimneys, mirrors, &c., being manufactured here - and also has mineral wool factories and paper mills.

Thus we start '3 from the point of view of a world of separate persons and things, in which thought mirrors these concrete realities, taken as ultimate subjects of predicates.

Both mirrors are usually concave; if plane, a concave lens is placed immediately before them.

Light passing through a vertical slit falls upon the mirrors, from which it is reflected, and two images of the slit are produced, one by the movable mirror attached to the magnet and the other by the fixed mirror.

The width of the photographic sheet which receives the spot of light reflected from the mirrors in the above instruments is generally so great that in the case of ordinary changes the curve does-not go off the paper.

To overcome this difficulty Eschenhagen in his earlier type of instruments attached to each magnet two mirrors, their planes being inclined at a small angle so that when the spot reflected from one mirror goes off the paper, that corresponding to the other comes on.
