For example, each variation in speed of the light-producing waves of ether causes a specific reaction in the brain. For one speed of ether waves the reaction is the perception of the color blue; for another, yellow; for another, violet.
I take a scrap of the epidermis and manage to separate pretty nearly half of one of the shining belts. I place my preparation under the microscope. On the skin a sort of white-wash lies spread, formed of a very fine, granular substance. This is certainly the light-producing matter. To examine this white layer more closely is beyond the power of my weary eyes.
Then muttering something as to the cleverness of this light-producing instrument, he motioned to his daughter to take it from Bickley and hold it in a certain position. She obeyed, and in its illumination he began to study the engraved plates, holding one of them in either hand.
The thick air-tube supplying the light-producing sheet increases the flow of air and the light is intensified; the same tube, swayed by the animal's will, slackens or even suspends the passage of air and the light grows fainter or even goes out. It is, in short, the mechanism of a lamp which is regulated by the access of air to the wick. Excitement can set the attendant air-duct in motion.
Aleck felt no disposition whatever to talk about the venture his companion in misfortune had proposed, for he was intent upon getting to the spot where the light-producing implement had been bestowed, and twice over he nearly lost his calmness, for the horrible idea attacked him that he had wandered quite away from the spot in the darkness.

Indeed, he has often felt that with all the light-producing energy and with all the rapid movement of the aurora it was mysterious that there should be absolutely no sound. The aurora often looks as if it ought to swish, but to his ears it has never done it; so much phosphorescent light might naturally be accompanied by some chemical odour, but to his nostrils never has been.
They saw no more of the globular creatures which had haunted the ruins of the cathedral, but, instead, there appeared around the bell an immense multitude of small luminescent animals, many of them most beautifully formed, and emitting from their light-producing organs various exquisite colors which turned the surrounding water into an all-embracing rainbow.
The filaments of the carnivorous trees are garlands of lamps; the eyes of the hunting animals, electric globes; the insignificant bacteria, light-producing little glands all of which open or close with phosphorescent switches according to the necessity of the moment, sometimes in order to persecute and devour, and at others in order to keep themselves hidden in the shadows.
