-s HE HAS GOT 1T.
-4IlsIAsTIe OVER HIS NEW 5s LAMP

,s oser New Toy.
 Edison has had the new
 bolnar rsadiness for some time, but
 Ill a5y is,'9,, to show it until he had
 not loted the accessories,
 lels@ aatgd a New York Herald re-
 Pleasantly the other day and
 aWeIl. I've got it. y
 ba led the way into the room
 ls4 tbe X ray experiments have been
 tad I Here was B transformation.
 u. 'lls and the ceiling of the room
 Wa, Narored with light eolored paper,
 ser to bring out the effect of the
 f1e closed the door, and we were
 u,,tion darkness till Edison shout
 ~ FaOnp' His assistant ill the next
 " 4arnea on the current, and the new
 sbone out, suspended in the center
 " l 1;abt was a beautiful one, clear
 np s,bife and, while MT, Edison said
 v was only 316 or candle power,
 as inc light was turned on and off
 aIternated with the 16 candle pow
 ;acandescent lamp, there was not
 .b difference between them in lllu-
 hating power. ,
 ba new lamp is simply Crookes M If the usual shape, about 5 inches E and J inches ill diameter. The
 8Harity of the light is ill the interior
 tbe bulb. When it is being made,
 If . thimbleful of crystals of a new I stance is introduced into the bulb,
 tbe latter is slowly rotated in an <sSnse heat just short of the melting #Intof the glass. The result is that the sStals c5 this new substance are dis
 ,nted evenly all over the interior of N bnIb and are fused by the high heat N tbey form a coating on the inside.
 fr Edison was asked what this new Ebstance was, and he laid his finger on \ side of his nose, and, with a quiz Eal look, replied; Don't you wish |n knew? But am not going to tell "a Let these other fellows that know E,nuch find out what it is if they can. ' AlI lsat he would say was that 1t was |aatura. mineral, very abundant and |Fy cheap, and that it possessed nearly Aeee times the fluorescent properties of M tungstate of calcium, which was |so the discovery of the wizard. How do you expect to get greater Esht?"
 That is very simple" he replied; All that you have to do is to increase @ size of the bulb and you get the |Iger amount of light. The fact is that Have succeeded in imprisoning the X Is ill the bulbs and there are none of sem that escape. I have tested very aefully for their presence outside Of Ie bulbs and there are none there. , AIr. Edison then said that the only Hng further to do was to work out the EDblem of commercial values and to Fercome some of the difficulties i'll pro- being the light
 He said Why, this thing is star. Ing revelation in the wonderful econ Iny of energy. When first reached the sult brought out my ammeter and g yoltmoter tc test the electrical en gy required, and I was dumfounded ben the calculation was finished at the lomous saving. l was sure that thers as some mistake about the matter and ist the meters were wrong. 1 got 6 sond set and then a third, and still e results agreed, and realized what Ienormous economizer of energy this sE lamp was. "
 \ What were the fgures?" T found that the lamp of 315 or i ldle power, he replied, figured up 9energy consumption of only 39 foot Ands per candle power, while it iS Fll known that the incandeseent lamp now used requires about 150 foot pnds energy per candle power. Put 1t pther way. Taking 3S. 900 foot pounds Ethe horse power and dividing by 39 Ind one horse power equal to S46 of ese lamps.
 Have you tried them i'll multiple arc Puits? ?''
 Yes, and they work as we'll or better ah slngly, and so that part of the )blem is solved
 Have you succeeded ill getting the avs direct from the current and with the intervention of the Ruhmkorff l?"
 Ne; that has not yet been done. n see, the conditions are peculiar. re l have in this induced current an ensity of 40. GOO or 50. 900 volts, with amperage that is practically nom. u So far no one has yet been able do this without the Ruhmkorff colt some other form of the induced cur, It. But l am at work on a new trans mer, which have great hopes of, that, successful, will accomplish Nsais very ut, and then we shall be able so get X rays direct frolu the main cur. ii. D
 ~ What lines are you now working well, Ill addition to this transform am working at the tubes to increase endurance tests and to simplify the iole and bring the matter into com. rcial shape. ?
 ,f, How long is rhat going to take?"
 well, you know just as much about ls :, as do The natter is one that ll II require large amount of hard aiyheal work, and until we get to end we shall not know. Yon may
