Some of the curious and puzzling empirical rules gained from the life-long experience of miners in regard to the varying richness and poorness of mineral lodes, according to the directions in which they strike whether north, south, east or west may very probably be explained, and to some extent justified, by the fuller light which science may throw upon the conditions determining the action of earth-currents in producing results similar to those of electro deposition.
The law of the mutual force in our model, however, is not the simple Newtonian law, but the much more complex law of the mutual action between electro magnets with this difference, that in the hydro-kinetic model in every case the force is opposite in direction to the corresponding force in the electro-magnetic analogue.
But perhaps of greater importance for this discussion, it is also used in making electroencephalograms." Rick and Scotty spoke in unison. "What?" Winston turned to them. "It's a long word, but not a difficult one. Electro for electrical. Encephalo is simply a Greek form meaning 'the brain. Gram, also from the Greek, means something drawn or written. A record, if you like.
When the undulatory current passed from the stylus to the chalk, the stylus slipped on the surface, and, being connected to a diaphragm, made it vibrate and repeat the original sounds. This "electro- motograph" receiver was, however, given up, and a combination of the Edison transmitter and the Bell receiver came into use.
A curious property of the machine is that at a certain speed, depending on the rapidity of the alternations in the coil, C, a continuous current passes from one commutator brush to the other, and it will energize electro magnets and perform other actions of direct currents. Here we have, then, a means of inducing direct currents from alternating currents.
Where Bortha hoarse, that loads the meads with sand, Rolls her red tide. Not that it was red when we passed, but electro purior. Through slaty hills whose sides are shagged with thorn, Where springs, in scattered tufts, the dark green corn, Towers wood-girt Harden far above the vale. And very dark green, almost blue, was the corn in September, 1888.
Prior to 1886 the refining of copper was the only electro- metallurgical industry and at that time it was carried on on a very limited scale. To-day the production of electrolytic copper as an industry is second in importance only to the actual production of that metal.
It is just conceivable, then, that the static form of the energy of light is electro static, that is, that the medium is electrically strained, and that the kinetic form of the energy of light is electro-kinetic, that is, that the motion is not ordinary motion, but electrical motion in fact, that light is an electrical vibration, not a material one.
I can fancy ladies going there and spending a right down happy time in looking at the dainty specimens of antique silver, and also the modern reproductions of old patterns in electro plate. I can, indeed, by a stretch of the imagination picture in my mind ladies who will go and look at many things at such a shop, admire all, and buy none.
In speaking of the horse power of an electro motor, I always mean the actual power developed in the shaft, and not the electrical horse power; this, therefore, should not be compared to the indicated horse power of a steam engine. I am indebted to Messrs. Yarrow for the principal dimensions and other particulars of a high pressure launch engine and boiler, such as would be suitable for this boat.
