And of all researches, it would be hard to find one tiat hIs resulted in so much definite bene fit to mankind as that in which Mr. Edison played so notable a part in tile year 1879. Long before 1879-in 1810 the are lamp\ was devised. By 1878 it had become well establish led for outdoor illumination. But it wis too powerfil for-hoie or office lighting. The task before the electrical researehers of the time was to "subdivide" it into inits smal enough for indoor use. Several men had nade inaidces cent lamps which radiated light from a carbonrod in aI partial vacuum to prevent the carbon from burning up instantly. But none of these crude 111111ps ol burn long enough to niake thein practical. Then Mr. Edison centered his remarkable taleit tirelessly uponii 1the problem in 1878.
