June 13, 1891. Samuel Insull, Esq., 2nd Vice-Pres’t., Edison General Electric Company, New York. My dear Sir:- I have your letter of 11th instant, enclosing copy of letter from Mr. H. Ward Leonard, in which he suggests that the [105?] volt lamps which we are making for alternating current circuits should be tested at the Lamp Works s an alternating current, preferably one which has been converted. I discussed this matter with Leonard when he was at the Laboratory the other day. There is no need of our getting an alternator, as we have one here now, together with everything necessary to subject the lamps to a good test. We are going to use a good many lamps at the Laboratory in testing alternator, and it will not be necessary to subject the lamps to any additional test. Yours truly, Thos A. Edison
