"Since arc lamps are connected in series, any particular lamp that is to be extinguished must be short-circuited. The dynamo is provided with appliances for maintaining a uniform current strength regardless of the number of lamps in use on its circiuit. When the number of lamps is increased, the voltage of the dynamo is correspondingly increased. ." -Avery 1895

"An improved form of the lamp, in which a portion of the cone B is removed to show the two parallel flat wicks A, A, which have each a separate slit or opening in the cone. C is the coincident winder for raising or lowering the wicks in the tubes, by which the wicks can be moved separately or simultaneously as desired. D is a lever for raising the extinguishers E, whereby not onl is the light instantly extinguished, but the wicks are also covered and protected from dirt, while all evaporation by the wick-holder is prevented." —The Encyclopedia Britannica, 1910

"Incandescence lamps operate essentially on the principle...[that] the current being sent through some substance that, because of its high resistance, becomes intensely heated and brilliantly incandescent. The only suitable substance known for such a resistance filament is carbon, which, carefully prepared and bent into a loop, is enclosed in a glass bulb from which the air is exhausted to prevent oxidation, i.e., combustion." -Avery 1895
