 Progress in Electric Lighting.
 From the account given by the correspond ent of the London Times (Aug. 2S) of the Electric exhibition in Vienna, we take the following interesting passage:
 s'An electric exhibition without light i!
 This has been for the last week the outcry
 of the Viennese people, or rather of the Vii
 ennese press. First of all, the Brush com
 pany was held responsible for the delay, then
 the firm which had supplied the steam en-
 zines for driving their machines and now it turns out that the only persons to blame were the mechanics who constructed the transmissions. However this may be, the exhibition has at last been thrown open to the public in the evening and was brilliantly illuminated last night. Although the lamps in the gallery round the central hall were not lit, the immense hall, which is considerably larger than the Albert Hall. presented the appearance of daylight. Nobody who has
 seen the Light exhibition at the Crystal Palace could help being struck with the fact that vast improvement has taken place in the quality of the arc light. This has to be ascribed to two oauses-hrst of all and chief ly, to the greater perfection in the eonstruc- tion of dynamos, and, secondly, to the greater simplicity of construction of the afc lamps. From repeated observations, extend ing over a whole week, which l devoted ex- cIusively to the study of machines and lamps, have come to the conclusion that our Eng fish made machines are greatly inferior 1n their details to Continental machines Moth ing can exceed the neatness and accuracy with which the Schuckert, the Gang and the
 Schwerd machines are constructed, and this accounts, to great extent, for the steadiness of the arc lamps of these firms.
 "A most important advance in incandes- cent lighting is for the first time practically illustrated on large scale at this exhibition. It is the possibility of turning on or of any number of incandescent lamps in one circuit without any special apparatus for the regula- tion of the current. This is done by means of the compound dynamos whose principle
 have shortly described in my previous letter. By simple manipulator, fastened to the wall near the machine, any number of in candescent lamps can be short-circulted. How important this is will easily be under stood on reminding your readers that all the incandescent systems, Edison, Lane-Fox, Maxim and Swan, have special apparatus for this purpose, all based on the principle ot introducing 8 greater or lesser resistance into the circuit. These special apparatus are no longer necessary, and great saving is thereby effected. All the known mean descent lamps are fully represented, and are used for lighting the furnished apart
 ments and the picture and art galleries in
 the east transept, and also some of the pa vilions containing the postofice exhibits ot the various countries. The English pavil- i ion is very prettily lighted by chandelier
 of Lane-Fox lamps, and is very comfort able lounge. One of the furnished rooms ceiling is pierced by 8 number of little glass stars, behind which an incandesceni lamp is placed thus giving the ceiling the appearance of Q star lit sky.
 'tIn all the rooms where the incaudescent lamps are used, it struck me what large
 number of lamps was required for lighting comparatively small area-as, for instance,
 a smoking room, about twelve feet square, fitted with thirty-six 'incandescent lights,
 presented very dingy appearance. And this brings me to 8 new incandescent lamp which, in my opinion, is destined to create
 revolution in incandescent lighting. It iE l well known that for street lighting and il
 lumination of large areas the incandescent l lamp has proved a failure. The Bernstein I lamp, exhibited by the Bernstein Electric Light Manufacturing company, of Boston, Mass, supplies this want. The ordinary in ! candescent lamp has very fine carbon fila | nent, with Q very small illuminating surface, ! The Bernstein lamp employs 8 hollow, semi circular carbon cylinder, which is quite ! elastic, and has a comparatively large | Illuminating surface. The lamp resembles l an ordinary incandescent lamp with thicker carbon filsment, but in. it's effects it differs materially from the ordinary type. With an electro-motive force of twenty three volts and a current of seven amperes, it has an Illuminating power of sixty five candles; it stands midway between an incandescent and an arc lamp. AS regards it's durability 1t has
 the great advantage of requiring but 8 low electro-motiye force-the higher the electro
 motive force the more rapidthe disintegration
 of the carbon fiIament and the shorter the
 durability of the lamp. The manufacturing
 process of the flament is not published yet,
 because the patents have not been completed
 for the different countries. The low electro
 motive force also permits the use of a very
 large number. of lamps in series, and, there
 fore, the illumination of long distances by
 means of very thin wire"
