On remelting of cast iron, increase in tensile strength was observed, which attained its maximum in iron with a small percentage of silicium after the third, and in such with a large amount after the fourth melting. The increase in tensile strength was accompanied by a loss of silicium, graphite, and manganese coupled with a simultaneous augmentation of combined carbon.
One had heard or so he alleged that "manganese" had been discovered somewhere up the valley before his time but he could remember his father telling of it. Mr Middlecoat stepped to the window and glanced out in to the square for a moment. He returned, and nervously bid "Ten more!"
If too much chameleon has been added, one may titrate back with an accurately estimated solution of manganese, which is prepared most easily by evaporating fifteen cubic centimeters chameleon solution down to two or three cubic centimeters, boiling with two to three cubic centimeters hydrochloric acid so long as the smell of chlorine is observed, and then diluting the solution to ten cubic centimeters, when one cubic centimeter of it corresponds to the same measure of chameleon.
A primitive winding-gear and a heap of slag marked the position of a small manganese mine which had been the cause for prolonging the single line railway so far into the Bush. To the west and south and north stretched scrub and bush, right away to forest and purple hills on the far horizon.
And so, for two years, they lived on at Castle Lashcairn; for long days sometimes Louis went off to Cook's Wall, and she despaired. Most of the time she hoped blindly. Much of the time they were incredibly happy in small things. Some slight measure of prosperity came to Loose End. The uncle who used to send the gramophone records retired from business and, buying himself an annuity, divided his money between his few relatives so that he could see what they did with it before he died. Quite a respectable flock of sheep came to take the place of those drowned in the flood and burnt in the fire; a horse and buggy went to and fro between Loose End and the station; Scottie the collie got busy and two shepherds came, building another hut at the other side of the run. A plague of rabbits showed Mr. Twist the folly of putting off the construction of rabbit-proof fencing any longer, now that he could afford it, and the gorse was once more left uncleared for months in the pressure of new things. Neighbours came, too the deposit of manganese at Cook's Wall was found cropping up on the extreme borders of Gaynor's run, and a tiny mining township called Klondyke settled itself round the excavations five miles from the Homestead. Marcella made friends with everyone, to Louis's amazement. To him friendliness was only possible when whisky had taken away his self-consciousness; the parties of miscellaneous folks who turned up on Sundays, bringing their own food, as is the way in the Bush where the nearest store is often fifty miles away, worried him at first. He stammered and was awkward and ungracious with them, but Marcella, dimly realizing that it must be bad for him to be drawn in so much upon their égoïsme
We shall endeavor to show in that which follows, that copper, zinc, nickel, and cobalt, and even iron, manganese, cadmium, bismuth, and tin, whether they be present as sulphates, chlorides, or nitrates, may be precipitated and separated from each other by electrolytic methods much more rapidly than by any previously known process.
This chemical is a salt, made by roasting wolfram with soda ash, and wolfram is a native tungstate of iron and manganese. This soda preparation is used commercially in making garments fire-proof, and Joe had learned this from Mr. Herbert Waldon, the chemist. He had decided to use this instead of an alum solution, which is credited with great fire-resisting qualities.
Their commercial missions seem to be much less interested in establishing business connections than in taking photographs. The chief commercial activity all three countries are intensely interested in is getting concessions from Mexico for iron, manganese and oil materials essential for war. President Lázaro Cárdenas, however, has stated his dislike of fascism on several occasions.
At the cataracts of the great rivers Orinoco, Nile, and Congo, the syenitic rocks are coated by a black substance, appearing as if they had been polished with plumbago. The layer is of extreme thinness; and on analysis by Berzelius it was found to consist of the oxides of manganese and iron.
Milky quartz was scattered over them, although no similar formation was visible; of manganese, basalt, and ironstone, with other substances, there were now no indications. None of these fragments had been rounded by attrition, but still retained their sharp edges and seemed to be little changed by time. Mr.
