[D8639Q], Letter from Edison Machine Works, Charles Batchelor to Thomas Alva Edison, June 8th, 1886

Title: [D8639Q], Letter from Edison Machine Works, Charles Batchelor to Thomas Alva Edison, June 8th, 1886
Editor's Notes: Enclosing blue print of one quadruplex line and regular bank of lamps on dynamo; little banks will be duplicated for every line; we "also furnish for each quadruplex as shown in between the ground and the single transmitter which is equal to three lamps"; since these are under the table, "thought it better to make them of german silver resistance instead of lamps." What do you think? [Blueprint attached]
