Everywhere there is building going on very modest building, it is true, with rough-and-ready masonry or timber, and roofs of zinc painted in strips of light colors, but everywhere there are signs of progress and growth. People look bored, but healthy, and it does not surprise me in the least to hear that though there are a good many inhabitants, there is not much society.
The repulsive force which zinc and silver exercise together being far superior to that of gold and silver, I have found that when a frog, prepared and armed with silver, is galvanized under water, the conducting arc of zinc produces contraction as soon as one of its extremities approaches the muscles within three lines distance; while an arc of gold does not excite the organs, when the stratum of water between the gold and the muscles is more than half a line thick.
CHAFING. One of the best remedies is powdered lycopodium; apply it every time the babe is cleaned; but first wash with pure castile soap; Pears' soap is also good. A preparation of oxide of zinc is also highly recommended. Chafing sometimes results from an acid condition of the stomach; in that case give a few doses of castoria.
The deposition of zinc from a solution of zinc sulphate would require +2.67 volts, but, since the deposition of hydrogen from sulphuric acid solution requires only +1.90 volts, the quantitative deposition of zinc by electrolysis from a sulphuric acid solution of a zinc salt is not practicable. On the other hand, silver, if present in a solution of copper sulphate, would deposit with the copper.
Many persons would willingly sacrifice 2s. 6d per hour for the convenience, but a great item connected with the employment of zinc batteries is in the exciting fluid, and the trouble of preparing the zinc plates frequently. The process of cleaning, amalgamating and refilling is so tedious, that the use of primary batteries for locomotive purposes is extremely limited.
Anyway, such being the effect of yellow wine upon Ouk, and such being the effect of Ouk on Madame Maubert, they both leaned their elbows upon opposite sides of the zinc counter that evening and looked at each other.
So long as he had his mother, and his mother smiled at him, life was all sunshine. He gave his name to the teacher, and answered all her questions readily, and was duly enrolled as a pupil in Grade I, along with Bennie Cowan, Edgar Zinc and Bessie Brownlees, and set at work to make figures.
With zinc the electrolytic and electro-thermal processes have not been able yet to compete with the older metallurgical method of distillation, but an important industry is electro- galvanizing, where a solution of zinc sulphate is deposited on iron and gives a protective coating.
"He is a mad old man, they said," Olivia told him, "down there they call him Malakh that means 'salt' because they said he always weeps. We had stopped to look at a metallurgist yesterday he had some zinc and some metals cut out like flowers, and he was making them show phosphorescent colours in his little dark alcove.
The effects produced are magnificent, especially by the sulphide of calcium and sulphide of zinc. From the disruptive discharge coil they glow intensely merely by holding them in the hand and connecting the body to the terminal of the coil.
