te lephorus

[Gr. telos -end, and phoros = bearing.] Entom .: The typical genus of Telephorine (q. v.). They are known to children, from their colors, as Soldiers and Sailors. They are seen in meadows on plants, but are carnivorous. According to De Geer, the female sometimes devours the male. of increasing the power, as by using both poles of the magnet, and in other ways. The microphone, on the other hand, uses the power of a battery in its circuit, but in some respects appears le delicately sensitive than the free membrane. In practice it is very general to employ some form of microphone as the transmitting or speaking instrument, and the Bell telephone, or one of its modifications, as the receiving or hearing instrument. There are now many forms of telephone in use, the principal varieties besides those already enumerated being the bi-telephone, in which there are two receivers, one for each ear; the capillary telephone, in which electro-capillarity is used to produce telephonic effects; the chemical telephone, in which chemical or electrolytic action is utilized; the electrostatic telephone, which utilizes electro: static disturbances in the reproduction of sound; the reaction telephone, in which mutually reacting coils are used; and the thermo-electric telephone, in which a thermo-electric battery is used. The last-named telephone has never been used in practice. In 1892 a long-distance telephone was erected between Chicago and the larger eastern cities and has since been in succe ful operation. telephone-doctor, s. (See extract.) "At every exchange there is an official called the 'wire chief' whose special duty is to overlook the making of connections between the subscriber's line and the switch board, to inspect the wires, and to test them electrically in order to determine the position of any defect that may occur in a subscriber's line or instruments. The wire chief sits at a special desk from which wires run to various parts of the system, and he is provided with electrical instruments with which to make on lines that develop 'trouble.' He is the telephone - doctor of the plant, and his wires give him the advantage of being truly ubiquitous. He receives complaints and reports of 'trouble' and enters on special slips every 'trouble' re of ported or discovered. These slips are handed to 'trouble men,' who search out the cause, and, finding it, apply the proper remedy; they then enter an account of what they found and what they did on the slip and return it. In this way a close and comprehensive check is kept on the operation of the telephone plant, which, on account of its complexity and the number of small parts that go to make it up, is peculiarly liable to trifling but troublesome defects. Returns are made up periodically from the 'trouble slips' and these form a continuous record of the efficiency both of the plant and of those immediately in charge of it." -Chicago News, Aug. 9, 1894. těl'-ě-phone, v. t. & i.
