Some of them gave me a hint to melt down my plate by asking if it were not lead. I had two pewter plates and a piece of zinc which I now melted into bullets. I also spent the remainder of my handkerchiefs in buying spears for them. My men frequently surrounded herds of buffaloes and killed numbers of the calves.
The walls and floor were lined with sheets of zinc A young man stood stiffly to attention in the middle of the room. Miss Willmot stared at him. Then she turned to Sergeant O'Rorke. "Shut the door please, sergeant, and wait outside." The young man neither stirred nor spoke. "Tommy!" said Miss Willmot. Private Collins, miss, 8th Wessex Borderers." He spoke in a tone of hard, cold fury.
The managers of mines of copper as well as of gold and silver have learned to economize; and it has been found that instead of letting these fumes go into the air, they may be made to pass through acid chambers lined with zinc and full of water. The water holds the fumes, and can be used in making sulphuric acid. After the ore has been roasted, it is put into the furnace for smelting.
While waiting, with the road-cart drawn up close to the curb, Steering and the girl could hear talk all about them, zinc and lead, jack, jack, jack!
Mushet, however, observes that "the general use of hardened copper by the ancients for edge-tools and warlike instruments, does not preclude the supposition that iron was then comparatively plentiful, though it is probable that it was confined to the ruder arts of life. A knowledge of the mixture of copper, tin, and zinc, seems to have been among the first discoveries of the metallurgist.
Two plates, one of copper and the other of zinc, were placed in an acid solution and a current flowed through an external wire connecting the two plates. But Volta never found the right explanation of why his cell was working.
The heat was intense, and walking, out of training as we were, was dry work; our iron casks being new, gave a most unpleasant zinc taste to the water, which made us all feel sick. Unpleasant as this was, yet it served the useful purpose of checking the consumption of water.
The far-off glory of the mountains was blotted out, as though it had never been; and the doll's house, with its subsidiary group of native huts, had the aspect of a dwelling in Cloudland. From within came the plash of water falling drop by drop, suggesting a vision of zinc tubs, pails, and basins, set here, there, and everywhere, to check the too complete invasion of the saturated outer world.
Then came Gervaise Macquart with her four children: bandy-legged, pretty, and industrious Gervaise, whom her lover Lantier turned into the street in the faubourg, where she met the zinc worker Coupeau, the skilful, steady workman whom she married, and with whom she lived so happily at first, having three women working in her laundry, but afterward sinking with her husband, as was inevitable, to the degradation of her surroundings.
If, however, the solutions of such ores are treated with sulphureted hydrogen or sulphurous acid, instead of zinc or stannous chloride to reduce the iron, and the excess reducing agent removed by boiling, an accurate determination of the iron can be made. PROCEDURE. Grind the mineral to a fine powder. Weigh out two portions of about 0.5 gram each into small porcelain crucibles.
