It has been supplanted by the electrical current in some of the most beautiful and useful phenomena of our time. Electrolysis is the name of the process by which fluid chemicals are decomposed by the current. A familiar early experiment in electrolysis is the decomposition of water a chemical composed of oxygen and hydrogen, though always thought of and used as a simple, pure fluid.
"Well then, say `I'm a beastly cad, and a funk, and a sneak, and I knuckle under and will never do it any more." "I'm a beastly cad," gasped Parson, choking with shame, anger, and sulphuretted hydrogen, "and a funk, and a sneak, and I knuckle under and will never do it any more." "Now all the rest of you say it!" Telson, Bosher, and King obeyed, one after the other. "Is that all of you?"
This spectrum, which has been recognized along with that of hydrogen in the light of the tails of comets, indicates a carbide, probably acetylene. By P. CARLES. When tinned iron serves for containing alimentary matters, it is essential that the tin employed should be free from lead.
Science would say, you only require certain combinations of oxygen, hydrogen, nitrogen, and carbon, to sustain all the activities of the physical body. Apparently, this is true. Upon the surface it is, but in reality it is not; because if it were really true there could be no famines. Science could make bread out of stones, as was suggested at the temptation of Christ in the wilderness.
Carbon, hydrogen, oxygen, and nitrogen are all lifeless bodies. Of these, carbon and oxygen unite in certain proportions and under certain conditions, to give rise to carbonic acid; hydrogen and oxygen produce water; nitrogen and other elements give rise to nitrogenous salts. These new compounds, like the elementary bodies of which they are composed, are lifeless.
One ampere decomposes .00009324 gramme of water per second, liberating .000010384 gramme of hydrogen and .00008286 gramme of oxygen. The quantity in grammes of any other chemical element or ion which is liberated from an electrolyte or body capable of electrochemical decomposition in a second by a current of one ampere is given by what is called the electrochemical equivalent of the ion.
The putrefaction of animal and other azotized bodies is a chemical process, by which they are gradually dissipated in a gaseous form, chiefly in that of carbonic acid and ammonia; now to convert the carbon of the animal substance into carbonic acid requires oxygen, and to convert the azote into ammonia requires hydrogen, which are the elements of water.
We found many patches of stagnant water, which, when disturbed by our passing through them, evolved strong effluvia of sulphureted hydrogen. At other times these spots exhibit an efflorescence of the nitrate of soda; they also contain abundance of lime, probably from decaying vegetable matter, and from these may have emanated the malaria which caused the present sickness.
The thermometer dropped to minus 43 degrees Fahrenheit, and the voyagers felt a ringing sensation in their ears. The first long voyage accomplished was about the same period, by a balloon constructed by Monsieur Robert, which was filled with hydrogen. It was 56 feet in height, and 36 in diameter.
The hydrogen will burn in the oxygen, giving heat; and if the two gases are mixed in the right proportions and then ignited, they explode with violence. This energy was derived from the electricity. It was stored by decomposing the water. Energy is stored by chemical means by causing it to do work in opposition to the force of chemism, or chemical affinity.
