The lead does not bond to the plate as well as either of the other metals zinc, tin, copper, or any alloys of them. The following table gives the increase in weight of different articles due to hot galvanizing: Tin is often added to the hot bath for the purpose of obtaining a smoother surface and larger facets, but it is found to shorten the life of the protective coating very considerably.

Instruments fabricated from these alloys, recommended by the use of ages, the perfection of the art, the splendour and polish of their surfaces, not easily injured by time and weather, would not soon be superseded by the invention of simple iron, inferior in edge and polish, at all times easily injured by rust, and in the early stages of its manufacture converted with difficulty into forms that required proportion or elegance."

Arsenide of zinc was similarly treated, the arsenic becoming precipitated in like manner on the platinum electrode. Various other alloys, being experimented upon, gave similar results.

The powerful instrument used at Baltimore for photographing spectra, and the measuring engine constructed to fit the photographs so that its readings give the wave lengths of lines directly within 1/100 of a division on Angström's scale, give the foregoing results a weight superior to many others published. Writing on some curious properties of metals and alloys, Mr.

The dynamite had dug a ditch more than a hundred feet wide, all around us, and cast up an embankment some twenty-five feet high on both borders of it. As to destruction of life, it was amazing. Moreover, it was beyond estimate. Of course, we could not count the dead, because they did not exist as individuals, but merely as homogeneous protoplasm, with alloys of iron and buttons.

To him, as to Farrell, she was the 'little saint' and peacemaker, with her lovingness, her sympathy, her lack of all the normal vanities and alloys that beset the pretty woman. That she was not a strong character, that she was easily influenced and guided by those who touched her affections, he saw.

It was read and reread with great eagerness by every member of the household. The iron ore cropped out on every hand. There was apparently mountains of it; one could see it in the stones along the road. But the difficulties met with in separating the iron from its alloys, together with the expense of transportation and the failure of certain railroad schemes, caused the works to be abandoned.

The urgent necessity for an extension in the manufacture of Bessemer steel, and of the new and remarkable alloys in which very small quantities of other metals are employed in order to impart altogether exceptional qualities to iron, must accentuate the demand for those kinds of ore which lend themselves most readily to the special requirements of the works on hand.

In current Earth science tin and mercury and a few alloys could be made into superconductors by being cooled below 18° Kelvin, or four hundred odd degrees Fahrenheit below zero. Above that temperature, superconductivity did not exist. But the children's wire was a superconductor at room temperature. A thread the size of a cobweb could carry all the current turned out by Niagara without heating up.

Not separating the true from false, accepting in the dark without discrimination, is like a shop where gold and its alloys are sold together, justly condemned by all the world. The foolish masters, practising the ways of superficial wisdom, grasp not the meaning of the truth; but to receive the law as it explains itself, this is to accept the highest mode of exposition.
