... are several instances of remarkable similarity of properties. Thus there is a strong resemblance between platinum and iridium; bromine and iodine; iron, manganese, and magnesium; cobalt and nickel; phosphorus and arsenic; but this resemblance consists mainly in their forming isomorphous compounds in which these elements exist in the same relative proportion. These compounds are similar, because the atoms of which they are composed are arranged ...

... valley, whose lofty walls are beveled away on both sides so as to embrace it all without admitting anything not strictly belonging to it. The foreground was now aflame with autumn colors, brown and purple and gold, ripe in the mellow sunshine; contrasting brightly with the deep, cobalt blue of the sky, and the black and gray, and pure, spiritual white of the rocks and glaciers. Down through the midst, the young Tuolumne was seen pouring from its crystal fountains, now resting in glassy pools as ...

... which no more lead entered than in common flint glass, and therefore incapable of being affected by any articles of food contained or prepared in such vessels. With these materials, either in their natural white or variously coloured—black by manganese, blue by cobalt, brown and buff by iron—he produced imitations of the Etruscan vases, and of various other works of ancient art, such as the world had never before seen—such as no subsequent artist has ever attempted to rival. His copies ...

... Looey, very sad, like they was closte personal friends of his'n. And he told me all about them and how Young Cobalt had done fur them. But from what I could make out it all happened away back in the early days. And shucks!—I didn't care a dern, anyhow. I told ...

... in that resonant bass voice of his. "I'm ready to report for degree-of-completion credit that the mining properties on Xosa II are prepared as of today to deliver pig iron, cobalt, zirconium and beryllium in commercial quantities! We require one day's notice to begin delivery of metal other than iron at the moment, because we're short of equipment, but we can furnish chromium and manganese on two days' ...

... in the leafless shrubbery, too—wine-red stems of dogwood, ash-blue berry-canes, and the tangled green and gold of willows. And over all a pale cobalt sky, and a snow-covered hill, where, in the woods, crows sat cawing on the taller trees, and a ...

"When our mining experts discover a mineral belt containing precious metals or copper, iron, lead, nickel, platinum, cobalt, quicksilver, manganese or any other ore used in manufactures and the arts, the first thing we do is to sink a shaft on the most likely ore chimney and at every one hundred feet in depth we run levels to ...

... four miles to Fontainebleau, bought his cobalt, and set his face homewards about three o'clock. When he was halfway home, he turned aside into a tangle of young beech wood, parted the branches, and found a shady corner where he could rest and think. The sun was very hot, the high road was scorched by it. But it was not heat or fatigue ...

The virgin surface of the snow lay glittering gold and silver in the early morning sun, with here and there, as a contrast, the long shadows of the limbs of a great oak or elm, cast as though some one had traced its pattern for fun with a brushful of the purest cobalt. ...

Another, Eastpool, a tin and copper mine, from which ores to the amount of 130,000 pounds have been won, after an original outlay of only 640 pounds. From the former mine native silver, cobalt, and bismuth have also been obtained. The mineral deposits of Cornwall, it should be known, are found in granite and grey slate. Those of Derbyshire and the north of England—lead and ...

Even the United States lacks (mentioning minerals only) nickel, cobalt, platinum, tin, diamonds. Its supplies of the following are inadequate: antimony, asbestos, kaolin, chromate, corundum, garnet, manganese, emery, nitrates, potash, pumice, tungsten, vanadium, zirconium. Outside of minerals we lack ...

... happy in this beautiful bright studio, whose open casements were hung with myrtle and passion-flower, and whose silence was filled with the singing of nightingales. Cobalt, with a touch or two, became the loveliness of summer skies at morning; the Lakes and Carmines bloomed in a thousand exquisite flowers and fancies; the Chromes and Ochres (mere dull earths) were allowed to spread themselves in sheets of gold that took the shine ...

... The trees were tossing and bending in the thrilling blue air. There was a bronzy tint in their foliage, as though they were putting on olive drab in honour of the general. Great balloons of silver clouds scoured across the cobalt sky. At one minute to 11 Pershing appeared at the top of the stand. The whole square, massed with people, shook ...

(for the youth is short-sighted, though he hardly as yet knows his misfortune)—if he has made some effort extraordinarily successful, our young Pygmalion hides away the masterpiece, and he paints the beauty with all his skill; the lips a bright carmine, the eyes a deep, deep cobalt, the cheeks a dazzling vermilion, the ringlets of a golden hue; and he worships this sweet creature of his in secret, fancies a history for her; a castle to storm, a tyrant usurper who keeps her imprisoned, and a prince in black ringlets and a spangled cloak, who scales the tower, who slays ...

It also exists as an impurity in the ores of several metals—iron, copper, silver, tin, zinc, nickel, and cobalt. Sulphuric acid is frequently impregnated with arsenic from the iron pyrites used in preparing the acid. It is a constituent of many rat pastes, vermin or weed killers, complexion powders, sheep ...

Now the chemists of a steel works' laboratory may have to determine also the tungsten, chromium, vanadium, titanium, nickel, cobalt, phosphorus, molybdenum, manganese, silicon and sulfur, any or all of them, and be spry about it, because if they do not get the report out within fifteen minutes while the steel is melting in the electrical furnace ...
