[D8828AAD], Letter from Joseph Ballard Murdock to Thomas Alva Edison, January 13th, 1888

Editor's Notes

"In accordance with your request to write you in January about our diving lamp, I submit the following. ### We would like for experimental purposes, a lamp requiring about 70 to 80 volts and giving about 100 candles. An approximation to these figures is all that is needed at first. After the lamp has been tested practically, modifications might suggest themselves. Your suggestion of testing insulation and strength under pressure of ten atmospheres under water would cover the requirements. It is desirable of course to have the lamp as small as possible. ### We are hoping for a successful development of a direct connected dynamo at your hands. I may be in New York shortly, and if so will try to visit Orange. Please call on me for any information you may wish about either lamp or dynamo." I remain, respectfully yours, J.B. Murdock [Marginalia--"give to John att"]
