The largest pond is as sensitive to atmospheric changes as the globule of mercury in its tube.
Mercury is found in New South Wales and Queensland.
The principal mining product is mercury, extracted at Idria, while iron and copper ore, zinc and coal are also found.
A battery with a sufficient number of cells is connected to these two electrodes so as to pass a current through the mercury vapour, negative electricity proceeding from the mercury cathode to the iron anode.
Even in the Leiden papyrus the astronomical symbols for the sun and moon are used to denote gold and silver, and in the Meteorologica of Olympiodorus lead is attributed to Saturn, iron to Mars, copper to Venus, tin to Hermes (Mercury) and electrum to Jupiter.
GayLussac, who obtained it by heating mercury or silver cyanide; this discovery is of considerable historical importance, since it recorded the isolation of a "compound radical."
In the same way the arrangements finally elaborated by Lodge and Muirhead consisted of a direct coupled antenna and nearly closed condenser circuit, and a similar receiving circuit containing as a detector the steel wheel revolving on oily mercury which actuated a siphon recorder writing signals on paper tape.
At Meshed i Sar, the port, or roadstead of Barfurush, the steamers of the Caucasus and Mercury Company call weekly, and a brisk shipping trade is carried on between it and other Caspian ports.
Then he treated oil of vitriol in the same way, but got nothing until by accident he dropped some mercury into the liquid, when "vitriolic acid air" (sulphur dioxide) was evolved.
Heating spirits of hartshorn, he was able to collect "alkaline air" (gaseous ammonia), again because he was using mercury in his pneumatic trough; then, trying what would happen if he passed electric sparks through the gas, he decomposed it into nitrogen and hydrogen, and "having a notion" that mixed with hydrochloric acid gas it would produce a "neutral air," perhaps much the same as common air, he synthesized sal ammoniac. Dephlogisticated air (oxygen) he prepared in August 1774 by heating red oxide of mercury with a burning-glass, and he found that in it a candle burnt with a remarkably vigorous flame and mice lived well.
The atomist has an easy answer; he says that the new body is made up by the juxtaposition of the atoms of iodine and mercury, which still exist in the red powder.
For, if the Sun presides over the first hour of Sunday, and therefore also over the eighth, the fifteenth and the twenty-second, Venus will have the twenty-third hour, Mercury the twenty-fourth, and the Moon, as the third in order from the Sun, will preside over the first hour of Monday.
The current can be passed into and out of the movable coil by permitting the ends of the coil to dip into two mercury cups.
The views of Becher on the composition of substances mark little essential advance on those of the two preceding centuries, and the three elements or principles of salt, mercury and sulphur reappear as the vitrifiable, the mercurial and the combustible earths.
The next salt to be obtained was the mercuric salt, which was prepared in 1 799 by Edward Charles Howard, who substituted mercury for silver in Brugnatelli's process.
By ca-sing two conical surfaces of cast-iron immersed in mercury and contained in an iron vessel to rub against one another when pressed together by a lever, Joule obtained 776.045 foot-pounds for the mechanical equivalent of heat when the heavy weights were used, and 774.93 foot-pounds with the small driving weights.
Lodge, Muirhead and Robinson also devised a self-restoring coherer as follows: 3 - A small steel wheel with a sharp edge was kept rotating by clockwork so that its edge continually cut through a globule of mercury covered with paraffin oil.
Perfect electrical contact between the steel and mercury for low voltage currents, but when electric oscillations were passed through the junction it was pierced and good electrical contact established as long as the oscillations continued.
This device was converted into an electric wave detector as follows :-The mercury-steel junction was acted upon by the electromotive force of a shunted single cell and a siphon recorder was inserted in series.
The wheel was connected to a receiving antenna and the mercury to earth or to an equivalent balancing capacity.
Another form of receiver can be made depending on the properties of mercury vapour.
A highly insulated tube contains a little mercury, which is used as a negative electrode, and the tube also has sealed through the glass a platinum wire carrying an iron plate as an anode.
The mercury vapour then possesses a unilateral conductivity, and can be used to filter off all those oscillations in a train which pass in one direction and make them readable on an ordinary galvanometer.
The more important of those in use to-day are carbolic acid, the perchloride and biniodide of mercury, iodoform, formalin, salicylic acid, &c. Carbolic acid is germicidal in strong solution, inhibitory in weaker ones.
This or the biniodide of mercury is the last antiseptic applied to the surgeon's and assistants' hands before an operation begins.
Copper pyrites (copper), galena (lead), blende (zinc), cinnabar (mercury), &c. Of the sulphates we notice gypsum and anhydrite (calcium), barytes (barium) and kieserite (magnesium).
This is true not only of the major planets Mercury, Venus, the Earth, Mars, Jupiter, Saturn, Uranus and Neptune; it is also true of the host of more than five hundred minor planets.
Thus by heating spirits of salt he obtained "marine acid air" (hydrochloric acid gas), and he was able to collect it because he happened to use mercury, instead of water, in his pneumatic trough.
Subsequently electrum (an alloy of gold and silver) disappeared as a specific metal, and tin was ascribed to Jupiter instead, the sign of mercury becoming common to the metal and the planet.
Though an alchemist, Boyle, in his Sceptical Chemist (1661), cast doubts on the " experiments whereby vulgar Spagyrists are wont to endeavour to evince their salt, sulphur and mercury to be the true principles of things," and advanced towards the conception of chemical elements as those constituents of matter which cannot be further decomposed.
So late as 1782, James Price, an English physician, showed experiments with white and red powders, by the aid of which he was supposed to be able to transform fifty and sixty times as much mercury into silver and gold.
Mercury is a fluid, volatile, spiritual essence.
His opponent would be disposed to say that the iodine and the mercury ceased to exist when the red powder was formed, that they were components but not constituents of it.
After the suspension of the Reflector in 1753, he edited in the New York Mercury the "Watch Tower" section (1754-1755), which became the recognized organ of the Presbyterian faction.
3 If the day is divided into twenty-four hours and the planets preside in turn over each hour of the week in the order of their periodic times (Saturn, Jupiter, Mars, Sun, Venus, Mercury, Moon), we get the order of days of the week with which we are familiar.
When electric waves fell on the antenna they caused the mercury-steel junction to become conductive during the time they endured, and the siphon recorder therefore to write signals consisting of short or long deflexions of its pen and therefore notches of various length on the ink line drawn on the strip of telegraphic tape.
8-10) ascribed the victory to the magic arts of an Egyptian named Arnuphis who prevailed on Mercury and other gods to 2 Aurelius has been severely criticized for sending Verus.
Of mercury, and, when of specific gravity 1.295 (corresponding to about 80% of glycerin), it is distilled under a vacuum of 28 to 29 in.
Delisle is chiefly remembered as the author of a method for observing the transits of Venus and Mercury by instants of contacts.
Of the names of the planets Estera (Ishtar Venus, also called Ruha d'Qudsha, "holy spirit"), Enba (Nebo, Mercury), Sin (moon), Kewan (Saturn), Bil (Jupiter), and Nirig (Nirgal, Mars) reveal their Babylonian origin; Il or Il Il, the sun, is also known as Kadush and Adunay (the Adonai of the Old Testament); as lord of the planetary spirits his place is in the midst of them; they are the source of all temptation and evil amongst men.
F, Fixed coil; D, Movable coil; S, Spiral spring; T, Torsion head; MM, Mercury cups; I, Index needle.
The use of mercury cups is open to many objections on account of the fact that the mercury becomes oxidized, and such instruments are not very convenient for transportation.
The prima materia was early identified with mercury, not ordinary mercury, but the " mercury of the philosophers," which was the essence or soul of mercury, freed from the four Aristotelian elements - earth, air, fire and water - or rather from the qualities which they represent.
Thus the operator had to remove from ordinary mercury, earth or an earthy principle or quality, and water or a liquid principle, and to fix it by taking away air or a volatile principle.
This is briefly the doctrine that the metals are composed of mercury and sulphur, which persisted in one form or another down to the 17th century.
Thus in the Speculum Naturale of Vincent of Beauvais (c. 1250) it is said that there are four spirits - mercury, sulphur, arsenic and sal ammoniac - and six bodies - gold, silver, copper, tin, lead and iron.
Later, as in the works attributed to Basil Valentine, sulphur, mercury and salt are held to be the constituents of the metals.
Chaucer, Chanouns Yemannes Tale, where, however, mercury figures both as a spirit and a body: " The firste spirit quik-silver called is, The second orpiment, the thridde ywis Sal armoniak, and the ferthe brimstoon."
Van Helmont (1577-1644) was the last distinguished investigator who professed actually to have changed mercury into gold, though impostors and mystics of various kinds continued to claim knowledge of the art long after his time.
It may be obtained direct from pure and bright coloured portions of the native ore cinnabar, or, artificially, by subliming a mixture of mercury and sulphur.
The Trinity--the three elements of matter--are sulphur, mercury, and salt.
With an apparatus similar to the above, but smaller, made of iron and filled with mercury, Joule obtained results varying from 772.814 foot-pounds when driving weights of about 58 lb were employed to 775.352 foot-pounds when the driving weights were only about 192 lb.
It also forms amalgams with mercury, and on this account has been employed in dentistry for the purpose of stopping (or filling) teeth.
Lead, antimony, mercury and copper are also produced.
Those who believe the " Declaration " to be spurious argue that survivors remembered only one such document, that the Resolutions might easily be thought of as a declaration of independence, that Governor Martin in all probability had knowledge only of these and not of the alleged " Declaration," and that the dates of publication in the Raleigh and Charleston newspapers, and the politics of those papers, show that the Resolutions are authentic. In July 1905 there appeared in Collier's Weekly (New York) what purported to be a facsimile reproduction of a copy of the Cape Fear Mercury which was referred to by Governor Martin and which contained the " Declaration "; but this was proved a forgery.'
Of mercury it boils at 170° C. In an atmosphere of steam it distils without decomposition under ordinary barometric pressure.
Maybe it was the mercury in the tuna she ate or the excessive amounts of chocolate.
If 127 parts of iodine, which is an almost black solid, and loo parts of mercury, which is a white liquid metal, be intimately mixed by rubbing them together in a mortar, the two substances wholly disappear, and we obtain instead a brilliant red powder quite unlike the iodine or the mercury; almost the only property that is unchanged is the weight.
The perchloride of mercury is another very powerful antiseptic used in solutions of strength I in 2000, I in 1000 and 1 in 500.
But Jefferson was charged with plagiarism by those who believed in the authenticity of the " Declaration," and in 1833 there was discovered a proclamation of Governor Martin, dated the 8th of August 1775, in which he mentioned a publication in the Cape Fear Mercury of a series of resolves by a committee of Mecklenburg county which declared " the entire dissolution of the laws, government and constitution of the country."
Calculating the actual, societal costs of fatty foods, alcohol, cars, pet ownership, mercury thermometers, air conditioning, solar panels, razor blades, jogging shoes, and ten thousand other things, and incorporating those costs in the prices as taxes would lead to a vastly more efficient allocation of resources.
Sulphur is of an oily and fiery nature; in combination with salt by its fiery nature it arouses a desire in the latter by means of which it attracts mercury, seizes it, holds it, and in combination produces other bodies.
