Instructed by his experiments, and rendered competent by them to distinguish between primary and secondary results, he proceeds to establish the doctrine of 'Definite Electro-chemical Decomposition.
We begin skirmishing with a few light ideas, testing for thoughts, as our electro-chemical friend, De Sauty, if there were such a person, would test for his current; trying a little litmus-paper for acids, and then a slip of turmeric-paper for alkalies, as chemists do with unknown compounds; flinging the lead, and looking at the shells and sands it brings up to find out whether we are like to keep in shallow water, or shall have to drop the deep-sea line; in short, seeing what we have to deal with.
"Some of the advantages the electro-chemical process has over other cyanide processes are: Its cleanliness, quickness of action, cheapness, and large saving of cyanide of potassium by regeneration; not wasting the solutions, larger recovery of the gold and silver from the solutions; the cost of recovery less; the loss of gold, silver, and cyanide of potassium reduced to a minimum; the use of caustic alkali in such quantity as may be desired to keep the cyanide solution from being destroyed by the solidity of the pulp, and also sometimes to give warmth, as a warm cyanide solution will dissolve gold and silver quicker than a cold one.
The extent of Faraday's work in the electro-chemical field may be judged by considering some of the terms he proposed for its phenomena, most of which, with some trifling exceptions, are still in use.
Here, again, were broad proving grounds, for fuel and explosives; and, at one side, stood a low, skylighted group of brick buildings, known as the electro-chemical station. Dormitories and boarding-houses for the small army of employees occupied the eastern end of the enclosure, nearest the sea. Over all, high chimney stacks and the aerials of a mighty wireless plant dominated the entire works.
Laws of electro-chemical decomposition. In our conceptions and reasonings regarding the forces of nature, we perpetually make use of symbols which, when they possess a high representative value, we dignify with the name of theories. Thus, prompted by certain analogies, we ascribe electrical phenomena to the action of a peculiar fluid, sometimes flowing, sometimes at rest.
