Instead of practical experiment I have come to the conclusion that I can best advance the subject by making a theoretical investigation of the effects produced upon a voltaic current by the vibration of the conducting wire in a liquid included int he circuit - and deducing thence the best way of increasing the amplitude of the electrical undulations so as to admit of the transmission of vocal utterance over long distances.
