But as, at that unhappy period of our history, some persons assumed a shabby exterior for safety, and as he might have had some other and sufficient reasons for disguising himself, I awaited an explanation, although I opened the way to it. 'What a plight you are in, my dear Mongenod! I said, accepting the pinch of snuff he offered me from a copper and zinc snuff-box.
Side by side with this, as if in ironic illustration of the other side of the life of the Ghetto, was a seeming royal proclamation headed V.R., informing the public that by order of the Secretary of State for War a sale of wrought-and cast-iron, zinc, canvas, tools and leather would take place at the Royal Arsenal, Woolwich.
Without delay Jack connected the cells in proper series, and removing the wire between the instrument and the iron post, substituted the battery zinc to the post, and copper to the instrument. Then once more he caught up the severed end of the main-line wire, and touched the opposite side of the instrument. A cry of triumph, then a mighty shout, greeted the responding click.
I picked up a zinc basin and once more stepped into the outer gloom. The well was only a few yards off I could just distinguish its black mouth. I placed my basin on the edge. I grasped the cold, wet rope and lowered the bucket into the depth. I drew it up again and emptied it into my basin the bits of ice floating in the water knocked sharply against the zinc.
The platina is shorter than the zincs, to prevent its reaching the quicksilver in the bottom of the cell; and the wax balls on its sides are to insulate it from the zinc plates. This platina should never be allowed to touch the mercury or the zinc. Let the plates, properly screwed together, be now placed in the cell with the Battery Fluid.
Castings coated with acid zinc rust comparatively quickly, even when the porosity has been reduced by oxidation, aggravated no doubt by some of the corroding agents sal-ammoniac, for instance being forced into the pores of the metal.
The cost of the exciting fluid varies, however, considerably; it may be a solution of salts, or it may be dilute acid. Considering the zinc by itself, the expense for five electrical or four mechanical horse power through an efficient motor, in a small launch, would be 2s. 6d. per hour.
It was noticeable, however, that the pyrite crystals which were free from zinc, galena, or other extraneous matter received no gold precipitate. Those which had such foreign associations were beautifully covered with fine gold crystals."
If I had only asked what I can't ask of you now'; and, Holcombe, she flushed just like a little girl, and laughed, and said, 'Oh, will you, Lloyd? And you see that ugly iron chapel up there, with the corrugated zinc roof and the wooden cross on it, next to the mosque?
Michigan illustrated attractively her great copper industry; the deposits of this metal among the primary rocks of her northern section being the richest in the world. Of special interest were the mining products of New Jersey. This state furnished minerals not found anywhere else; for instance the franklinite a compound of iron, zinc, and manganese named from Dr. Franklin.
