Welsbach, has discovered a composition which is as good a non-conductor that is to say concentrator of heat as platinum, is much more durable, and a great deal cheaper.
I recalled a night I once spent in a Bowery lodging-house for "local colour." Only this was infinitely worse. No law regulated this house. There was an atmosphere of cheerlessness that a half-blackened Welsbach mantle turned into positive ghastliness. Our guide introduced us. There was a dead silence as eight eyes were craftily fixed on us, sizing us up. What should I say?
Shirley looked up at his daughter, and the lines on his face relaxed as though he would hide his disappointment from her eager eyes. "Confound that light! What's the matter with it?" he exclaimed, changing the subject, and glancing up at the gas-fixture. Kennedy had already been intently looking at the Welsbach burner overhead, which had been flickering incessantly.
"Yes," cried Kennedy excitedly. "I got my first clue from that flickering Welsbach mantle last night. Of course it flickered from the wireless we were using, but it kept on. You know in the gas- mantle there is matter in a most mobile and tenuous state, very sensitive to heat and sound vibrations.
The shaded Welsbach lights of the chandelier cast a dazzling luminance on the tea-table of snow and silver, while leaving the pictures in a gloom so discreet that not Ruskin himself could have decided whether these were by Whistler or Peter Paul Rubens.
By a slight turn the glass hat reminded me of Auer's light, and I knew that I was about to invent something which was to make me as rich and independent as his invention had made my countryman, Dr. Auer, of Welsbach; then I should be able to travel instead of remaining in Vienna. In the dream I was traveling with my invention, with the, it is true, rather awkward glass top-hat.
Presently she went into the study and lit the Welsbach over the table, and curled herself up in Simeon's great chair to enjoy her periodicals, and then her eye fell upon a parcel of proof, directed but not sent, and she read the address, weighed and stamped the package, and rang the bell for the servant to post it.
Daylight had scarcely begun to fail; but nevertheless the man's tone announced a grievance, that, with half-a-dozen women in the house, he the exhausted breadwinner should have been obliged to attend to such a trifle. Bessie sprang to pull the chain of the Welsbach tap, and the white and silver of the tea-table glittered under the yellow light.
In the mean time, however, while electricity for lighting purposes has, to say the least, not made any startling advances, we have, besides the regenerative lamps before mentioned, the new Welsbach light, which is exhibited before you to-day, by the kindness of Dr.
Wallace a gentleman who is well known to us as one well qualified to test its merits has found that the Welsbach burner produces a light equal to more than 9 candles per cubic foot of gas of 25 candle power, thus nearly doubling the amount of light compared with gas consumed in the ordinary way.
