The chief exports are oil-cake, flint, cod and Benedictine liqueur.
The crucibles or pots used for the production of optical glass very closely resemble those used in the manufacture of flint glass for other purposes; they are " covered " and the molten materials are thus protected from the action of the furnace gases by the interposition of a wall of fireclay, but as crucibles for optical glass are used for only one fusion and are then broken up, they are not made so thick and heavy as those used in flint-glass making, since the latter remain in the furnace for many weeks.
The church of St Mary exhibits Decorated and Perpendicular stone and flint work.
Flint chips, which appear to have been fashioned by hand, are said to have been found in the Miocene beds, but to prove the existence of man at so early a period would require stronger evidence than has yet been brought forward.
The implements found in the relic bed under it were axe-heads of stone, with their haftings of stag's horn and wood; a flint saw, set in a handle of fir wood and fastened with asphalt; flint flakes and arrow-heads; harpoons of stag's horn with barbs; awls, needles, chisels, fish-hooks and other implements of bone; a comb of yew wood 5 in.
An argument for discontinuity of race is found in the fact that whereas the Sumerians are never represented as using the bow, their predecessors certainly made flint arrowheads.
The rock on the surface is as hard as flint, but underneath it gradually softens and furnishes an admirable stone for building which can be sawn into blocks of any size, hardening on exposure to the atmosphere.

The essential materials of which these mixtures are made are, for English flint glass, sand, carbonate of potash and red lead; for plate and sheet glass, sand, carbonate or sulphate of soda.
Nevertheless, disks of optical glass, both crown and flint, have been produced up to 39 in.
There were 88 glass 88 It is probable that the flint-glass of that date was very different from the flint-glass of to-day.
The duty on flint-glass was imposed on the molten glass in the crucibles and on the unfinished goods.
It is the development of this craft in connexion with the perfecting of flint-glass that makes the 18th century the most important period in the history of English glass-making.
It is found in the form of oxide (silica), either anhydrous or hydrated as quartz, flint, sand, chalcedony, tridymite, opal, &c., but occurs chiefly in the form of silicates of aluminium, magnesium, iron, and the alkali and alkaline earth metals, forming the chief constituent of various clays, soils and rocks.
Sand consists of grains of quartz or flint, the individual particles of which are large enough to be seen with the unaided eye or readily felt as gritty grains when rubbed between the finger and thumb.
During the first year of Henry's reign Hotspur further was appointed justiciar of North Wales and constable of the castles of Chester, Flint, Conway, Denbigh and Carnarvon.
Her most interesting contributions are crust-corals (Gorgonidae, Corallium, Isis, &c.), and especially flint-sponges, called by the Japanese hoshi-gai and known as glass-coral (Hyalonema sieboldi).
The church of St Nicholas is a fine Perpendicular structure exhibiting the flint-work common to the district, and possessing a beautiful south porch and the ruin of a massive western tower which partly collapsed early in the 18th century.
Its roof is a single flat stratum of limestone; its walls are well marked by lines of stratification; dripstone also partly covers the walls, fills a deep fissure at the end of the cave, and spreads over the floor, where it mingles with an ancient bed of ashes, forming an ash-breccia (mostly firm and solid) that encloses fragments of sandstone, flint spalls, flint implements, charcoal and bones.
With figure of the god of the underworld (Mictlantecutli) as regent of the tenth of the 20 sections, each of 13 days of the tonalamatl, which begins with "one flint" (ce tepcatl).
Flint has dealt with the following antitheistic theories: atheism, materialism, positivism, secularism, pessimism, pantheism and (in a separate volume) agnosticism.
The coasting trade consists chiefly of imports of coal and provisions, the exports being principally timber for shipbuilding and flint for the Staffordshire potteries.
The discovery of flint implements of the same types as those found in Egypt, Mauritania, and Europe show Somaliland to have been inhabited by man in the Stone age.
The epoch is characterized by flint implements of the rudest type and never polished.
The first actual find of a palaeolithic implement was that of a rudely fashioned flint in a sandbank at Menchecourt in 1841 by Boucher de Perthes.
If the worldpowers were hard as flint in their dealings with Israel, the people of God were steeled to such moral endurance that each clash of their successive onsets kindled some new flame of devotion.
The Welsh mines are chiefly in Flint, Cardigan and Montgomery shires; the Scottish in Dumfries, Lanark and Argyll; and the Irish in Wicklow, Waterford and Down.
For the practical measurement of field intensity du Bois has used plates of the densest Jena flint glass.
Flint has important manufacturing interests, its chief manufactures being automobiles, wagons, carriages - Flint is called "the vehicle city," - flour, woollen goods, iron goods, cigars, beer, and bricks and tiles; and its grain trade is of considerable importance.
The settlement of the place, then called the Grand Traverse of the Flint, began in 1820, but Flint's growth was very slow until 1831, when it was platted as a village; it was chartered as a city in 1855.
Upon that was raised a wall of rough rubble rudely faced with stone and flint, evidently a medieval work and about 22 ft.
Flint glass particularly, which appeared quite satisfactory when viewed in small pieces, was found to be so far from homogeneous as to be useless for lens construction.
Guinand was induced to migrate from his home in Switzerland to Bavaria, where he worked at the production of homogeneous flint glass, first with Joseph von Utzschneider and then with J.
On the other hand, while in the older crown and flint glasses the relation between refraction and dispersion had been practically fixed, dispersion and refraction increasing regularly with the density of the glass, in some of the new glasses introduced by Abbe and Schott this relation is altered and a relatively low refractive index is accompanied by a relatively high dispersion, while in others a high refractive index is associated with low dispersive power.
The older optical glasses, now generally known as the " ordinary " crown and flint glasses, are all of the nature of pure silicates, the basic constituents being, in the case of crown glasses, lime and soda or lime and potash, or a mixture of both, and in the case of flint glasses, lead and either (or both) soda and potash.
With the exception of the heavier flint (lead) glasses, these can be produced so as to be free both from noticeable colour and from such defects as bubbles, opaque inclusions or " striae," but extreme care in the choice of all the raw materials and in all the manipulations is required to ensure this result.
The potash-lead glass, which was first used on a commercial scale in England for the manufacture of table-ware, and which is known as " flint " glass or " crystal," is also largely used in France, Germany and the United States.
The term flint-glass is now understood to mean a glass composed of the silicates of potash and lead.
Injurious as the excise duty undoubtedly was to the glass trade generally, and especially to the flint-glass industry, it is possible that it may have helped to develop the art of decorative glass-cutting.
Hoffman founded at New York the Knickerbocker (1833-1860), which soon passed under the control of Timothy Flint and became extremely successful, most of the leading native writers of the next twenty years having been contributors.

According to Flint, 4 there were four men who in this and the preceding century seized and made prominent this idea, namely, Bodin, Bacon, Descartes and Pascal.
Hulme, however, who has carefully investigated the subject, is of opinion that flint-glass in its present form was introduced about 1730.
The scope of the archaeologist's studies must include every department of the ancient history of man as preserved in antiquities of whatever character, be they tumuli along the Baltic, fossil skulls and graven bones from the caves of France, the flint implements, pottery, and mummies of Egypt, tablets and bas-reliefs from Mesopotamia, coins and sculptures of Greece and Rome, or inscriptions, waxen tablets, parchment rolls, and papyri of a relatively late period of classical antiquity.
