"Acetylene, as you may know," he hastily explained, never pausing for a moment in his work, "is composed of carbon and hydrogen. As it burns at the end of the nozzle it is broken into carbon and hydrogen--the carbon gives the high temperature, and the hydrogen forms a cone that protects the end of the blowpipe from being itself burnt up."英文原著 · 《The Silent Bullet》
I will notice one of the principal causes having a tendency to prevent the perfect uniformity of chemical action, between the iodine and silver; hydrogen, or the moisture in the atmosphere, makes a very perceptible barrier. This moisture may arise as the result of the cold, from a want of friction in the buffing of the plate, which, coming in contact with the warmer air, as a writer on this subject says:英文原著 · 《American Hand Book of the Daguerreotype》
The chlorides dissolve in water; give with nitrate of silver, a white precipitate, even in highly diluted solutions, becoming violet colored and finally black when exposed to the light. The rapidity of the change of color is proportioned to the intensity of the light. It is insoluble in nitric acid, but readily soluble in ammonia; it fuses without decomposition, forming, when cold, a tough, horny mass, and is reduced by hydrogen and by fusion with carbonate of soda, or with resin.英文原著 · 《American Hand Book of the Daguerreotype》
I generally tried to turn them loose. One day I got a new man, and told him to conduct a certain experiment. He got a quart of ether and started to boil it over a naked flame. Of course it caught fire. The flame was about four feet in diameter and eleven feet high. We had to call out the fire department; and they came down and put a stream through the window. That let all the fumes and chemicals out and overcame the firemen; and there was the devil to pay. Another time we experimented with a tub full of soapy water, and put hydrogen into it to make large bubbles.英文原著 · 《Edison, His Life and Inventions》

The saloon was small, and in its atmosphere the odours of meat and drink struggled for the ascendancy. The pig and the cabbage wrestled with hydrogen and oxygen. Behind the bar Schwegel laboured with an assistant whose epidermal pores showed no signs of being obstructed. Hot weinerwurst and sauerkraut were being served to purchasers of beer. Curly shuffled to the end of the bar, coughed hollowly, and told Schwegel that he was a Detroit cabinet-maker out of a job.英文原著 · 《Heart of the West》
