It is his opinion that it is probably eliminated as a chloride from the tissues of the body to the electrodes in the bath in which the patient is wholly or partly immersed. On the positive electrodes we get the peroxide. On the negative there is a spongy metallic form of lead. But it is only a small amount." "The body has been removed?" asked Craig. "Not yet," the masseur replied.
When the electrodes are connected in series with the primary coil of a transformer and a source of direct current having a potential of 40 to 110 volts, bubbles of gas are formed on the end of the platinum, or alloy anode, which prevent the current from flowing until the bubbles break and then the current flows again, in this way the current is rapidly made and broken and the break is very sharp.
The electrodes employed in electro-analysis are almost exclusively of platinum, since that metal alone satisfactorily resists chemical action of the electrolytes, and can be dried and weighed without change in composition. The platinum electrodes may be used in the form of dishes, foil or gauze.
Owing to the carbonates that are always present in sewage, ferrous carbonate is also formed. The success of these laboratory experiments led me to a trial of the process on a larger scale, for hitherto only a gallon at any one time had been treated. Small brick tanks were erected at my wharf at Peckham and iron electrodes fitted to them.
But if an incandescent lamp is operated with currents of very high frequency, the action of the gas cannot be neglected, and the rules for the most economical working must be considerably modified. In order to bring such a lamp with one or two electrodes to a great perfection, it is necessary to employ impulses of very high frequency.
Take B D current, with small pointed electrodes. If the eye be turned inward, insert P. P. in the outer angle of the eye, so as to bear upon the rectus externus, and N. P. in the inner angle, so as to bear on the rectus internus. Let the current be of what force the patient can bear. Withdraw the electrodes frequently, to rest the eye, and then reapply them.
The more powerful action of such a pair is explained by the stronger excitation and more rapid regeneration that the negative electrodes undergo from the oxidizing action of the air in the potash solution, as well as by the fact that this solution is a better conductor than the sal ammoniac solution.
Spencer," said Kennedy to me, "that it is no sleight-of-hand trick and that the professor has not several uncut stones palmed in his hand like a prestidigitator." The Frenchman faced us, his face livid with rage. "You call me a prestidigitator, a fraud you shall suffer for that! Sacrebleu! Ventre du Saint Gris! No man ever insults the honour of Poissan. Francois, water on the electrodes!"
Thus he concludes that when the same quantity of electricity is caused to pass through a series of cells containing acidulated water, the electro-chemical action is independent of the size of the electrodes. He next proves that variations in intensity do not interfere with this equality of action.
Now I think that it is perfect." He drew up the lever, removed the electrodes, and there lay a dozen bricks of ruddy sparkling gold. "You see, according to our calculations, our morning's work has been worth twenty-four thousand pounds, and it has not taken us more than twenty minutes," remarked the alchemist, as he picked up the newly-made ingots, and threw them down among the others.
