Abstract

(Copy) The Edison United Manufacturing Co. 65 Fifth Avenue. New York, Feb. 1, 1889. W.M. Laffan, Esq. Manager, N.Y. Sun, Park Row, City. Dear Sir:-- You have now been using the Edison lamps for a period sufficiently long eo enable you to determine whether or no our representations, made to you, to induce you to replace the Sawyer-Mann lamp with ours, were correct.##As you will readily see, having used these lamps from the time we equipped your entire plant, they have had a life of over one thousand hours and we understand less than ten per cent of the number originally installed by us have actually burned out, therefore you have undoubtedly made an economical change.##Will you kindly advise us if our statements, as above, are correct. And oblige, Very truly yours, The Edison United Mnfg. Co.
