The small planishing hammer, Figs. 1 to 3, next page, is used for copper, tin, electro, and iron plate, for scythes, and other thin work, for which it is sufficient to adjust the force of the blow once for all by hand, according to the thickness and quality of the material before commencing to hammer it.
Not but that the materials of her dress are rich enough, so that my electro simile will hardly hold water; but money does not make the artist. Let us begin with the bonnet. Walk down Collins Street at the time of the block on Saturday, and I doubt whether you can count half a dozen bonnets which are both pretty and suitable to the face and head of the wearer.
In this case the magnetic rotations are produced in an electro magnet by means of alternate currents supplied by alternating Gramme machine. In order to better explain the action, it will be necessary to refer to a new electro-motor, which was the subject of an article in the Electrical Review of February 19 last.
"As an object lesson on the subject of good roads, the introduction, and constantly increasing use, of bicycles, motor cycles, motor freight wagons, automobiles, electro mobiles, locomobiles, and the entire class of vehicles equipped with rubber tires, has aroused a widespread interest, which is prophetic of great results.
We can cut off the power from any single motor by the mere break of contact between two pieces of metal; we can restore the power by merely letting the two pieces of metal touch; we can make these changes by electro magnets with the rapidity of thought, and we can deal as we please with each of one hundred motors without sensibly affecting the others.
This great-grandfather shop, so to speak, has, indeed, been established for more than a century, and when the present proprietor first went to the business the trade done was chiefly in silver and silver made goods, whereas now it is largely in electro plate, in jewellery, cutlery, &c.
Parachutes and rail-roads man-traps and spring-guns! And who shall calculate the immense influence upon social life upon arts upon commerce upon literature which will be the immediate result of the great principles of electro magnetics! Nor, is this all, let me assure you! There is really no end to the march of invention. The most wonderful the most ingenious and let me add, Mr. Mr.
This "secondary" or reacting current is evidently due to the polarisation of the foils that is to say, the electro- positive and electro-negative gases collected on them. Professor Groves constructed a gas battery on this principle, the plates being of platinum and the two gases surrounding them oxygen and hydrogen, but the most useful development of it is the accumulator or storage battery.
If the solarization be very deep, apply the lamp beneath, and warm the plate a trifle. Now pour off, and, without rinsing, apply the gilding. The whole operation must be quickly performed, or the chlorine soon attacks the shades of the picture. When properly done, however, the solarized parts are restored to a clear, transparent white. Electro, or Cold Gilding.
In another respect the Victorian is the direct opposite of the Parisienne. If you leave general effects, and come to pull her dress to pieces, you find that the metal is only electro, to whatever rank of life she may belong. The general appearance may be pleasing, but in detail she is execrable.
