May 9, 1890 Francis R. Upton, Esq., Edison Lamp Company, Harrison, N.J. Dear Sir:- Referring to the attached bill for twenty-five dollars, for six Mercury Pumps shipped to the Duke of Marlborough, Mr. Edison says that you might not charge him for these. You do considerable business abroad, and these pumps were sent forward in the general interest of trade. Yours truly, A.O. Tate
