As regards the figures given in the cutting you enclose you will have observed that the voltage necessary to kill a dog is stated to be between 300 & 700 volts for continuous currents within 30 secs####100 & 250 - -alternating - - -####and 900 & 2100 - - continuous - - 2 secs####300 & 750 - - alternating - - - -####Now none of us know I think what it takes to certainly kill a man, and consequently to state any voltage that will do so is to go "out of the [wood?]" as the lawyers say. I am inclined to think that an alternating voltage of 300 with good contact would kill a man, but I certainly do not think it would do so instantly. It would I imagine torture him first. I wanted to express a safe opinion and one which if carried out would produce painless because unconscious death to a criminal. I was not touching on the danger question from electric lighting at all in that paragraph. I think it would hardly be in good taste to alter the statement as it stands, but I can always state what I --- have the####honor to mention to you, if so doing would help you in any way. We are continuing the experiments for Mr Edison, and can kill a dog now more swiftly than a rifle bullet when desired.####I see Mr [barcher Weyde?] says in the Chemical World that we must have used 82,000 volts at Columbia College by mathematical calculation, not quite, he says but thinks 82,000 may be exaggerated but thereabouts. I am glad to think that a Siemens machine built for 100 volt lamps and a converter of 3 to 1 ratio can give a voltage of 80,000 or so but I am still more glad that I didn't know it at the time as I might have been nervous. I am sorry I wasn't present when Mr. Van der Weyde who doesn't recognize a voltmeter read his paper. PS Dr. Lodin of Columbis College for whom you are having a voltmeter made said his wires were still much entangled since the experiments there. Maybe, as he is a very quick fellow, you will let the man who takes the voltmeter fix him up as the Dr. is a chemist not an electrician.""},{"label":"Author","value":"Kennelly, Arthur Edwin"},{"label":"Recipient","value":"Hastings, Frank Seymour"},{"label":"Mentioned","value":["Electrical World","Columbia University"]},{"label":"Date","value":"1888-09-06"},{"label":"Type","value":"Letter"},{"label":"Subject","value":["Newspapers, books, other publications","Electrical distribution system","Electrocution"]},{"label":"Folder/Volume ID","value":"LM111-F"},{"label":"Microfilm ID","value":"109:138"},{"label":"Document ID","value":"LM111065"},{"label":"URL","value":"https://edisondigital.rutgers.edu/document/LM111065"},{"label":"Rights","value":"Thomas Edison National Historical Park"},{"label":"Publisher","value":"Thomas A.
