Abstract

Likes the new socket; could have made it before if abandoned placing switch on socket. But thinks the plaster socket is too cheap and shoddy. Edison's improvements would give 10 per hp lamps life ot 3-4K hours; but current life of 1k hours is pretty good now. Sorry that lamp mfg not yet profitable, but that must wait for central station to start up. It's been delayed for some months. Says Faure batty concern "is a fizzle; it has played out in France and has played out here. It is now denominated as the 'rotten battery'" b/c short life and high first cost. Will not realize "any of the great expectations held out by their bombastic proposals." Wants 100cp lamps for tests at Crystal Palace. Faure lamp however "has served the purpose of a forerunner." Biggs backed by Preece is coming up with another batty 4x as effiicient. There might be some lamp business in Biggs batty.
