LIGHT AND NO HEAT.
TEE REVOLUTIONARY INVENTION OF
 A NEWARK ELECTRICIAN.

Electricity the Source of the Incandesenoei
 No Carbon Fflament Used--Claims That
 He Win Yet Supply Electric Light sticlrs
 For the Vest Pocket.
 Mr D. Mcfarland Moore, the electri- elan of Newark, N j., has just patent ed an invention which will revolution ize electric lighting in more than one way. He announces that he has solved the problem of how to make light with out heat, something which has puzzled scientists for a generation, and with an ordinary 110 volt electric current he se- cures tho most beautiful white light from glass tubes. The apparatus which furnishes almost the luster of daylight is scarcely bigger than an ordinary tea cup, and the little machine through which tho current passes before it reach es it is not bigger than one's finger.
 The old incandescent light is produced by the action of a current passing through loop of carbon flament in vacuum bulb The new light comes from the passage of current through the vacuum itself without any carbon filament The inventor will hand the visitor . long glass tube, about as big as q broomstiek, and then put out all the light in the room. In q few seconds streams of light begin playing through the tube from one end to the other, with no wire connecting the tube with any apparatus It is mysterious and weird It is a species of electrical induction. The light is produced by what, for want of q better name. may be called ether vibrations. Mechanically speaking, to quote the inventor:
 ''I am using vibrations similar to those of an electric bell, putting them ill 9 vacuum and getting the result you see /"
 The apparatus for producing the new light is merely the small magnet and a glass tube the size of cigar. Within tho tube is supported a piece of watch spring. At one end of this is q small disk of soft iron, about quarter of an inch in diameter. Midway in length and in contact with the spring is an iron wire, the size of a pin. This wire extends through the glass, as does the wire attached to the watch spring. The air is then exhausted in the glass tube, leaving two metal contacts in high vacuum and permitting the spring to vibrate freely.
 When tho glass tube (called the vi- brator) is placed over the center of the magnet and the wires in the tube are connected with wires in the magnet, both being part of the electric circuit the current ill the primary current brings into existence q second current of sufficient strength toproduce the new light; whom this latter current is con nected with q dramatically sealed glass receiver, having absolutely nothing in it, artificial daylight is the result, through the vibrations of ether.
 One of these days the inventor hopes to put on the market sticks of electric light that can be carried in the vest pocket. He expects to make q tremen- dous saving ill the cost of producing electric light As at present. made only about one-seventh of one ton of coal is converted into light, all the rest being wasted in heat.
 When Mir Moore first applied to the patent office, the reply came that pat ent must be refused, as there was no law known to electrical science where by such devices would work EIr. Moore thereunen took his apparatus to Wash ington, illuminated a room in the pat ent office with the new light, which he had just been told would not work, and won complete victory, securing his patents without further question: This is the first public announcement of his discovery. It has been inspected by such scientists as Professor Anthony, former ly of Cornell university; Professors Croker and Pupin of Columbia college, Magee of Princeton and Demotte of Cambridge, all of whom approve of 1t and the principles used -Pittsburg Post Dispatch
