Manuscripts/Mixed Material Letter from Alexander Graham Bell to Mabel Hubbard Bell, July 17, 1881
Suggestions have been telegraped to me also from Prof. Trowbridge and from Prof. Rowland of John Hopkins University. I sent a cablegram to Mr. Preece as follows: “Can Hughes suggest form of Induction Balance to locate leaden bullet in President. If so cable at my expense.” No answer received as yet. I telegraphed to Davis and Watts for a workman. Mr. Watts replied that he was short of hands but would come on himself. He arrived Friday evening — At once stripped off coat and waistcoat and went to work upon construction of apparatus. We have constructed Balances of different sizes and get better and better results as we reduce the size of the apparatus. We are now constructing coils just the size of the leaden bullet itself and hope for still better effects.
Yesterday we were able to locate a bullet held in the clenched hand — and last night I located successfully a bullet hidden in a bag filled with cotton-waste. This looks promising. Maximum hearing distance yet obtained — two inches.
Shall see Dr. Woodward and make appointment with him to witness experiment.
Nothing further to add save that I am suffering less from heat than usual. Have filled out your cheque for fifty dollars — Please see that Johnson notes the amount drawn in the Charles Ruin hat. Bank cheque book so that our balance may be kept straight.
Have been staying in Washington — but came out here last night. I think of buying a study sofa for Papa for his wedding day (Tuesday) but don't know what to get for Mamma. Telegraph suggestion.
