A Hostilo and Sovero Critlclam by a Kolentltte Cheurtat, Tp the Editor of the Newo York Times, Feb, 13, So many glowing deseriptions on the one hand, or severe strictures of the Kdison ght and its inventor on the other, the latter by electricians, have recently apperred In the dally papers, that, possibly, the notes of an unbiased observer, tnken on tho field, may serve to enlighten the general reader as to what Mr. Edison lings actually accomplished. ‘The conclusions TL have artlyed at are cer- talnly without partisan blag, and, as 1 have recently Investigated with enre all the sys tems of eleetricn’ Hghting In use dn this country, it may be fairly claimed that they are bused upona pretty thorough study of tho whole subject, practically as well as theoretically, Exaetness of such a kind as would satisfy « man of sclentltic training was, unfortunately, unattalnable, elther frou orit testimony or records of Instrumental test. The work of the Inboratory appears to be carried on by Mr. Edison and his assist- ants with a consplenous disregard of exact measurement and registration of results, optical and electrical, as well xs economical, ‘The temperature was so low that the ont- line of the loop was perfectly visible to the eyontadistance of fifteen to twenty feet, aud the light, though goft aud mellow, Incked tho briliianey of the electric are, As Tun aT o derstand Mr. Edison and his assistants, the } photometric tests have not been yery exact or exhaustive, althongh shadow and oiled- paper tusts have been used, nnd tho light has nso been compared with that of a gas-jot by a process of neutralizing the ong by theother, or view versa, Mr. Edison stated the ihunl- nation produced by onu of hls Ianips to be equal to that of sixteen standard candles, but italld not strike me as. belug In excess of seven or elit catutles. ‘At the date of my visit ninety-two of these Iights were In operation In the Inboratory, in street lumps, and‘in stores and residences in the vieluity, the power being supplivd by two gonerators manifaetured under Edisoiws re- cent patent. ‘These will be deseribed here after, At this juncture It Ig only necessary to sny thit the ‘ninety-two Inmps were appir- ently somewhat ‘more than the two gencrators could carry, tha Incandescence of the Joops even in tho lamps in use in the Jaboratory for fine work being fur be- Jow the point required for the highest lunl- nosity, When asked whether ha tad mens- ured the temperature of the op, Mr Edison replied that he had not, anid cord not, theres fore, sny at what temperatire the highest: if hi-giving capacity of tho Innp was at- alned, the Incandeseence of bodies It would bo safe to say thatthe degree was not far above 4,000 Fahrenhelt; and it ny; ZI preaunlty be taken. for granted that elgnty lamps are alt that two generators can run withthe best ilunt- natlye results, Unfortunately, owing to the fact that the large eishty-horse power engine performs wll the motive work of the Inboratory and-shop, busldes driving the. generators, It Is not pos- sibls to state the horse-power consumed or absorbed by the latter. with absolute preelsion, Mr. Francis RK.
