"The mercury of a metal... represented its lustre, volatility, fusibility, and malleability; the sulphur of the metal, its colour, combustibility, affinity, and hardness."

"Traces of these ancient conceptions are still to be recognised in the word "quick-silver," that is living silver, a literal translation of argentum vivum. A term "quick-sulphur" (sulphur vivum) was also in use, but it has long since disappeared."

"Mercury, sulphur, and salt were not three matters, but one, derived from the '."

"The salt of the was merely a means of union between the mercury and the sulphur, just as the vital spirit in man unites soul and body. It was doubtless devised to impart a triple form to the idea, in conformity with the method of the theological schoolmen."

"They were thus able to apply the conception of the three principles to that of the four elements. Earth corresponded to philosophical sulphur, and water to philosophical mercury. Later, when they conceived philosophical salt, they devised a fifth element called "quintessence" or "ether." which corresponded to the third principle. Thus, if an alchemist distilled wood and obtained an inflammable gas, a liquid oil and a solid residue, he said that he had decomposed the wood into its elements—fire, water, and earth."

"[A]lchemists accounted for the diversity of metals by five causes:— 1. Variation in the proportion of the principles, mercury and sulphur. 2. Variation in the purity of these principles. 3. Variation in the duration of the period of concoction to which the compound was subjected in the bowels of the earth. 4. Variation in planetary influences. 5. Variation in accidental influences."

"The sulphur, the property of dryness and heat, ultimately overcame the mercury, the property of wetness and cold, and thus changes were effected. ...[S]ulphur was the father, mercury the mother, and metals were conceived between them. In this expression the philosophical principles are meant, not the ordinary substances called sulphur and mercury."

"The sulphur of a metal was its active principle; the mercury its passive; the salt was the link which united the other two."

"At a still later date it was argued that exact and natural sciences proceed by induction and deduction, and occult and spiritual sciences by analogy. Following out this line of thought the alchemists produced the following remarkable :—"

"He strongly maintained the virtues of aurum potabile (liquid gold), and wrote a book entitled Medicinae Chymicae et Veri Potabilis Auri Assertio (1610). Another tract, De Lapide philosophorum et Lapide Rebis, related to the older alchemy. ...[I]n alchemical symbolism "Rebis" was the name given to the hermaphrodite figure representing the union of the great philosophical principles, sulphur and mercury, in the operation of making the philosopher's stone..."

"He asserted that the metals are composed of the mercury and sulphur of the philosophers, to which he added philosophical salt. The philosopher's stone, he said, is composed of the same materials."

"These mystic alchemists interpreted the three principles in their own fashion. Mercury, the passive and female principle, was matter; sulphur, the active and male principle, was force; and salt, the middle term in the proposition, was movement, which applied force to matter. Or, expressed in another shape, mercury was the subject: sulphur, the cause; and salt, the effect. Symbolically, the theory was represented by an equilateral triangle, in one angle of which was the sign of sulphur or force; in the second, the sign of mercury or matter; and in the third, the sign of salt or movement."

"It's burning with a blue flame... giving off the most foul and acrid fumes... So there is our "burning stone," which in old English was called brimstone."

"[O]ne of the things that's associated with sulfur and... its compounds is unpleasant smells."

"Reminiscent of Aristotle, Jabir proposed... two exhalations: "earthy smoke" (small particles of earth on their way to becoming fire) and "watery vapor" (small particles of water on their way to becoming air). These, he believed, mingled to become the metals. But Jabir modified the Aristotelian approach by proposing that exhalations underwent intermediate transformations into sulfur and mercury before becoming metal. The reason for the existence of different types of metals, he believed, was that the sulfur and mercury were not always pure. He proposed that if the right proportions of sulfur and mercury with the right purity could be found... gold would result."

"Paracelsus' greatest triumph was the use of mercury to treat , the new disease of the day. ...Paracelsus may have heard of the treatment in his travels... or the discovery may have been serendipitous, based on... the extension of the mercury-sulfur theory of the Islamic alchemists to a tria prima... of mercury (soul), sulfur (spirit), and salt (body). But... there is no record of the number of people he adversely affected while experimenting with potions that were not effective, which may have been considerable."

"The word sulfur... goes... back to... the Hindu civilization... over 5,000 years ago. They had a word for sulfur... in... Sanskrit... sulvere... the enemy of copper. ...[T]hat is the ...destruction of the copper by the hot sulfur vapors... [T]he copper turns into... ...a black crumbly solid. ...The Latin [derived from sulvere] ...becomes sulphur."

"Sulphuric acid he made by distilling green vitriol (ferrous sulphate), and by distilling nitre (potassium nitrate), and (double sulphate of potassium and aluminium). he prepared, but said it was of little use as a medicine."

"He can perform a thousand things, and is the heart of all. He can perfect metals and minerals, impart understanding to animals, produce flowers in herbs and trees, corrupt and perfect air; in short, he produces all the odours and paints all the colors of the world. ...Know friend, that sulphur is the virtue of the world. And though Nature's second-born, yet the oldest of all things. To those who know him, however, he is as obedient as a little child. He is most easily recognized by the vital spirit in animals, the colour in metals, the odour in plants. Without his help his mother can do nothing."

"We have wonderful uses of on an everyday basis. ...[J]ust about every ...motorcar [which runs on diesel or on petrol] ...has sulfuric acid ...inside the car battery."

"[T]he most valuable work of Cavendish was contained in the two papers "Experiments on Air" (1784-5)... to determine the phlogistication of air... [i.e.,] the change in air when s are calcined in contact with it, and when sulphur, , or similar substances, are burned in it."

"Pliny recorded processes involving metals, salts, sulfur, glass, mortar, soot, ash, and a large variety of s, earths, and stones."

"All metals and minerals consist of certain principles. These were at first called "mercury" and "sulphur," not the ordinary substances... but a philosophical mercury and a philosophical sulphur."

"Putting a low price on valuable environmental resources is a phenomenon that pervades modern society. Agricultural water is not scarce in California; it is underpriced. Flights are stacked up on runways because takeoffs and landings are underpriced. People wait for hours in traffic jams because road use is unpriced. People die premature deaths from small sulfur particles in the air because air pollution is underpriced. And the most perilous of all environmental problems, climate change, is taking place because virtually every country puts a price of zero on carbon dioxide emissions."

"He noticed that when copper and sulphur are mixed, they exhibit an , which increases with increasing temperature until finally they combine, and all traces of electricity disappear. Hence, he inferred that the same forces which, acting on masses at a distance, produce electric phenomena, when acting on atoms at small distances, produce chemical combination, the positive electricity of the one atom attracting and holding the negative of the other. In the positive charge is on one and the negative on the other, but these two charges have to be discharged through the electrode before the elements are set free. This is the reverse of what takes place in combination. Davy in this view differed from the electro-chemical theory of Berzelius."

"The did not arrive in China until around 1500 BCE, and iron appeared only about 500 BCE, but by the beginning of their alchemical age, around 100 CE, the Chinese had knowledge of and ... mercury, sulfur and several of the common salts, such as ."

"By 3000 BCE the Sumerians, perhaps while heating copper to make it more malleable, had discovered that more copper could be retrieved from the fire if the metal were heated with certain types of dirt and stones—that is, certain earths. These earths were the metal s, and the process they discovered, ', reduced metal salts to pure metal by the action of in the fire. The process of changing metal salts into pure metal is known as reduction because the metal without the accompanying oxygen, , or sulfur of the salt weighs less than the ore. Eventually metal workers learned to distinguish various metal-bearing ores by color, texture, weight, flame color, or smell when heated (such as garlic odor of ores) and they could produce a desired material on demand."

"...let us rather choose Arm'd with Hell flames and fury all at once O're Heav'ns high Towrs to force resistless way, Turning our Tortures into horrid Arms Against the Torturer; when to meet the noise Of his Almighty Engin he shall hear Infernal Thunder, and for Lightning see Black fire and horror shot with equal rage Among his Angels; and his Throne it self Mixt with Tartarean Sulphur, and strange fire, His own invented Torments."

"There are several ways of performing Tas'id, (a rising up) in the (the sublimatory apparatus), and the substances which the chemists sublime in it are Mercury, Arsenic sulfide, Sulfur and Sal-Amoniac. They are placed after treatment in the aludel, and the cover being fitted in position over it, a fire is lit. Then the substance rises up, and settles on the shelf..."

"'isn't it brimstone morning?' 'I forgot, my dear,' rejoined Squeers; 'yes, it certainly is. We purify the boys' bloods now and then, Nickleby.' 'Purify fiddlesticks' ends,' said his lady. 'Don't think, young man, that we go to the expense of flower of brimstone and molasses, just to purify them; because if you think we carry on the business in that way, you'll find yourself mistaken, and so I tell you plainly. ...They have the brimstone and treacle, partly because if they hadn't something or other in the way of medicine they'd be always ailing and giving a world of trouble, and partly because it spoils their appetites and comes cheaper than breakfast and dinner. So, it does them good and us good at the same time, and that's fair enough I'm sure.'"

"[S]ulfur beautifully burning in a gas jar full of oxygen... is a blue flame... [W]e now have a jar full of sulfurous fumes... [W]e allow the water to mix... The water has been colored green with a... ... As if by magic, the water... [turns] red and now it's gone yellow. ...[T]he ...gas ...when it reacts with water ...makes ."

"This mineral ...is .... It's lead sulfide. ...Beautiful silver crystals. If you heat this strongly, this too will make sulfur come off."

"The natural principles in the mines are mercury and sulphur. All metals and minerals whereof there be sundry and diverse kinds are begotten of these two. But I must tell you that nature always intendeth and striveth to the perfection of gold. But many accidents coming between change the metals, for according to the purity and impurity of the two afore said principles, mercury and sulphur, pure and impure metals are engendered. Sulphur is not the last amongst the principles because it is a part of the metal. Yea, and the principle part of the philosopher's stone, and many wise men have left in writing diverse and very true things of sulphur. For the blood of sulphur is that inward virtue and dryness which congeals quicksilver into gold, and imparts health and perfection in all bodies."

"There is another type of exploding supernova that also seeds the Galaxy with elements. This is the . This explosion involves a binary system in which a star and an intermediate-mass star (a ) orbit each other. The two stars are so close to each other that the white dwarf gradually pulls a considerable amount of material from the outer envelope of the expanding red giant. At a certain point the white dwarf will acquire so much mass that it collapses under its own weight and produces an explosion that blasts the bulk of its material into the interstellar medium—mostly in the form of iron, but also some sulfur, and . Such explosions contributed about 70 percent of the iron we see today in the Galaxy."

"Volcanic ash, despite the name, is dense as rock and can cause significant damage to structures, power lines and communications. It is also toxic because it contains chemicals such as sulfur, chlorine or fluorine, and it can therefore affect water supplies."

"If you prudently desire to make our elixir, you must extract it from a mineral root. For as Geber saith, you must obtain the perfection of the matter from the seeds thereof. Sulphur and mercury are the mineral roots, and natural principles, upon which nature herself acts and works in the mines and caverns of the earth, which are viscous water, and subtil spirits running through the pores, veins, and bowels of the mountains. Of them is produced a vapour or cloud, which is the substance and body of metals united, ascending, and reverberating upon its own proper earth, (as Geber sheweth) even till by a temperate digestion through the space of a thousand years, the matter is fixed, and converted into a mineral stone, of which metals are made."

"Proposals for chemical weapons that arose during the American Civil War are described. Most incendiary and all biological agents are excluded. The described proposals appeared primarily in periodicals or letters to government officials on both sides. The weapons were usually meant to temporarily disable enemy combatants, but some might have been lethal, and Civil War caregivers were ill-prepared to deal with the weapons’ effects. Evidently, none of the proposed weapons were used. In only one instance was use against civilians mentioned. Among the agents most commonly proposed were cayenne pepper or other plant-based irritants such as black pepper, snuff, mustard, and veratria. Other suggested agents included chloroform, chlorine, hydrogen cyanide, arsenic compounds, sulfur, and acids. Proponents usually suggested that the chemicals be included in explosive artillery projectiles. Less commonly proposed vehicles of delivery included fire engines, kites, and manned balloons. Some of the proposed weapons have modern counterparts."

"The crude sulphur found in Sicily and other places is heated in pots, whereupon the sulphur melts and floats on the surface of the earthy matter which remains at the bottoms of the pots; the melted sulphur is poured into moulds, where it solidifies, and the earthy matter left in the pots is thrown away."

"Climate change is expected to exacerbate current stresses on water resources. On a regional scale, mountain snowpack, glaciers, and small ice caps play a crucial role in fresh water availability. Widespread mass losses from glaciers and reductions in snow cover over recent decades are projected to accelerate throughout the 21st century, reducing water availability, hydropower potential, and the changing seasonality of flows in regions supplied by meltwater from major mountain ranges (e.g. Hindu-Kush, Himalaya, Andes), where more than one-sixth of the world’s population currently lives. There is also high confidence that many semi-arid areas (e.g. the Mediterranean Basin, western United States, southern Africa, and northeastern Brazil) will suffer a decrease in water resources due to climate change. In Africa by 2020, between 75 and 250 million people are projected to be exposed to increased water stress due to climate change."

"... A is the area of a newly-formed landscape in front of a glacier, which was recently ice covered but has since been exposed by glacier retreat ... There are several fundamental advantages of using glacier forelands as field laboratories for ecological purposes. First, their restricted physical size facilitates comprehensive investigation. Second, with a relatively severe climatic environment, they support relatively simple ecosystems. Third, recently-deglaciated terrain has experienced only a short history of modification by changing natural environmental processes. Last, but by no means least, with increasing distance from a retreating glacier, a longer time period has been available for ecosystem development: hence the pattern of ecosystems on the glacier foreland is commonly interpreted as a spatial representation of temperate changed as a vast natural experiment."

"... Glaciers are formed on any portion of the earth’s surface that is permanently above the . This line varies locally in the same latitudes, being in some places higher than in others, but in the main it may be described as an elliptical shell surrounding the earth with its longest diameter in the tropics and its shortest in the polar regions, where it touches sea-level. From the extreme regions of the Arctic and Antarctic circles this cold shell swells upwards into a broad dome, from 15,000 to 18,000 ft. high over the tropics, truncating, as it rises, a number of peaks and mountain ranges whose upper portions like all regions above this thermal shell receive all their moisture in the form of snow. Since the temperature above the snow-line is below freezing point evaporation is very slight, and as the snow is solid it tends to accumulate in snow-fields, where the snow of one year is covered by that of the next, and these are wrapped over many deeper layers that have fallen in previous years. If these piles of snow were rigid and immovable they would increase in height until the whole field rose above the zone of ordinary atmospheric precipitation, and the polar ice-caps would add a load to these regions that would produce far-reaching results. The mountain regions also would rise some miles in height, and all their features would be buried in domes of snow some miles in thickness. When, however, there is sufficient weight the mass yields to pressure and flows outwards and downwards. Thus a balance of weight and height is established, and the ice-field is disintegrated principally at the edges, the surplus in polar regions being carried off in the form of icebergs, and in mountain regions by streams that flow from the melting ends of the glaciers."

"... As hydrological reservoirs, glaciers are seen by the public mainly for their contribution to , which they provide through their melting. This is admittedly of global interest and may change our planet in the long term, especially if the two ice sheets in Greenland and Antarctica are included. Somewhat less well known is the fact that glaciers are active landscape shapers and have in the past shaped not only high mountain relief but also large areas of North American and Central and Northern European lowlands. Anyone wishing to understand the formation of these glacial land surfaces cannot avoid considering the processes and effects of glacier erosion and deposition."

"Glaciers record climate changes in two ways: the deposits left during successive advances and retreat provide a coarse record of climatic change which, with careful study, a little luck, and a good deal of skill, can be placed in correct chronological order and dated. A more detailed record is contained in ice cores from polar glaciers such as the Antarctic and Greenland ice sheets. Isotopic and other chemical variations in these cores reflect past atmospheric circulation patterns, changes in temperature, and changes in the composition of the atmosphere. Changes during the past several centuries to several millennia can be quite precisely dated using core stratigraphy. Those further back in time are dated less precisely using flow models and proxy measures of other well-dated phenomena such as ."

"... sitting on a cold glacier, at night, in winter, with a stranger, in Iceland ... it was dark one minute, and then the next minute it wasn't. The , started to blaze. ... And this glacier we were sitting on — this bowl of ice — it started to pick up those lights. The whole glacier I was sitting on started to light up like a — like a . I felt like I was inside light."

"…Next Morn before Break of Day we directed our Steps to the anciently fame’d, but now ruin’d City of Canorein; the way to it is so delightsome, I thought I had been in England; fine Arable, Pasture, and Coppices; thus we passed Five Mile to the Foot of the Hill on which the City stands, and had passed half a Mile through a thick Wood, peopled by Apes, Tygers, wild Buffolo’s, and Jackalls; here were some Flocks of Parockets: When we alighted, the Sun began to mount the Horizon over the Hills, and under our Feet, as if he had newly bathed his fiery Coursers; there appeared the Mouth of a Tank, or Aqueduct, out of a Rock, whose steaming Breath was very hot, but water cold: From hence it is thought the whole City to be supplied with Water; for as we ascend, we find such Places, where convenient, filled with Limpid Water, not over-matched in India: If it be so, (as I know not how to contradict it) that it should have its Current upwards, through the hard Rocks artificially cut, the World cannot parallel so wonderful a Water-course! From hence the Passage is uneasy and inaccessible for more than two abreast, till we come to the City, all cut out of a Rock; where is presented Vulcan’s Forge, supported by two mighty Colosses, bellied in the middle with two Globes. Next a Temple with a beautiful Frontispiece not unlike the Portuco of St. Paul’s West Gate: Within the Porch on each side stand two Monstrous Giants [the Chaitya Caves, the giants being Buddhas], where two Lesser and one Great Gate give a noble Entrance; it can receive no Light but at the Doors and Windows of the Porch, whereby it looks more solemnly; the Roof is Arched, seeming to be born up by huge Pillars of the same Rock, some Round, some Square, 34 in number. The Cornish Work of Elephants, Horses, Lions; at the upper end it rounds like a Bow; near where stands a great Offertory somewhat Oval, the Body of it without Pillars, they only making a narrow Piatzo about, leaving the Nave open: It may be an 100 Feet in Length, in Height 60 Feet or more. Beyond this, by the same Mole-like Industry, was worked out a Court of Judicature (as those going to shew it will needs give Names) or Place of Audience, 50 Feet square, all bestuck with Imagery, Well Engraven according to old Sculpture. On the Side, over against the Door, sate one Superintendent, to whom the Brachmin went with us, paid great Reverence, not speaking of him without a token of worship; whom we called Jougy [jogi], or the Holy Man; under this the way being made into handsome Marble Steps, are the King’s Stables, not different from the Fashion of our Noblemens Stables, only at the head of every Stall seems to be a Dormitory, or Place for Devotion, with Images, which gave occasion to doubt if ever for that End; or rather made for an Heathen Seminary of Devotes and these their Cells or Chappels, and the open Place their Common Hall or School: More aloft stood the King’s Palace, large, stately and magnificent, surrounded with lesser of the Nobility. To see all, would require a Month’s time; but that we might see as much as could be in our allotted time, we got upon the highest part of the Mountain, where we feasted our Eyes with innumerable Entrances of these Cony-burrows, but could not see one quarter part. Whose Labour this should be, or for what purpose, is out of memory; but this Place by the Gentiles is much adored…the Portugals, who are now Masters of it, strive to erace the remainders of this Herculean Work, that it may sink into the oblivion of its Founders."

"The Pagod or Temple of the Canarin, whereof I intended to give an exact and true account, is one of the greatest wonders in Asia; as well because it is look’d upon as the Work of Alexander the Great, as for its extraordinary and incomparable Workmanship, which certainly could be undertaken by none but Alexander. What I most admire is that it is almost unknown to Europeans; for tho’ I have made much enquiry, I do not find that any Italian, or other European Traveller has writ of it… I climb’d the bare Craggy Rock with the Idolater, at the top whereof on the East side the great Pagod is hewn out, with other small ones by it."

"…in the centre of this Island there exists that wonderful Pagoda of Canari, thus called from its being supposed to have been the work of the Canaras. It is constructed at the foot of a great Hill of Stone of light grey colour; there is a beautiful Hall at its entrance, and in the yard that leads to the front back door, there are two human figures engraved on the same stone, twice as big as the Giants exhibited on the Procession of the Corpus Christi feast in Lisbon, so beautiful, elegant, and so well executed, that even in Silver they could not be better wrought and made with such perfection."

"There'll be blue birds over The white cliffs of Dover; Tomorrow, just you wait and see."

"The sea did what it liked, and what it liked was destruction. It thundered at the town, and thundered at the cliffs, and brought the coast down, madly."

"The Anthropocene makes for an easy story. Easy, because it does not challenge the naturalized inequalities, alienation, and violence inscribed in modernity’s strategic relations of power and production. It is an easy story to tell because it does not ask us to think about these relations at all. The mosaic of human activity in the web of life is reduced to an abstract Humanity: a homogeneous acting unit. Inequality, commodification, imperialism, patriarchy, racial formations, and much more, have been largely removed from consideration. ... Are we really living in the Anthropocene, with its return to a curiously Eurocentric vista of humanity, and its reliance on well-worn notions of resource- and technological-determinism? Or are we living in the Capitalocene, the historical era shaped by relations privileging the endless accumulation of capital?"
