Title
[D8123ZCQ], Letter from Francis Robbins Upton to Thomas Alva Edison, June 27th, 1881
Editor's Notes
Plumbago forms do not work as well as hoped. Possibly plumbago is causing a reduction reaction with the nickel. Will take Bergman two weeks to make 500 more forms. Compelled to wait till forms cool before putting in fibers. Went to Princeton to borrow a galvanometer from Prof. Brackett. Says that Brackett and Young have built a machine with plates on back; advises TAE to contact them about the machine and get an offer from them before the U.S. [Maxim] company learns about it. Consider for inclusion: this document seems to point in several directions. (DH)
