[D8136K], Letter from Alfred Abernethy Cowles, Ansonia Brass and Copper Co to Thomas Alva Edison, April 20th, 1881

Editor's Notes

Sending another coil of wire to replace that mistakenly used in lamp factory. Wishes to have insulation tested. It's a new compound, on this sample it's applied by hand and therefore imperfect. Please have its resistance tested, also the action of water on it.
