Title
[D8220O], Letter from Henry Draper to Thomas Alva Edison, May 14th, 1882
Editor's Notes
Finished installing lamps and machine; however, says that it is a mistake to put in the low resistance bobbin since with 2000 rpm can't get enough illumination. Wants to know if he has another bobbin of same size which generates more EMF.
