Title

[D8220L], Letter from Robert H Engle to Thomas Alva Edison, April 17th, 1882

Editor's Notes

"Please be kind enough to tell me where I can purchase one of your small incandescent electric lamps and the best form and number of cells of battery required to operate it successfully. The lamp to which I allude is the one where a spiral carbon is suspended in a vacuum in a glass bulb."
