    This paper seemed to take the impressions much more accurately, but a great many of the smaller vibrations were not recorded upon this either, and I could see that the vibration due to the trilled R's. were not perfectly formed also, or at least they differed considerably from the trilled R. indentations [[strikethrough]] when [[/strikethrough]]upon tin-foil.
    A few words that were upon this phonogram could be distinguished, as could also the trilled R's, but the words from a few lines of poetry which had been shouted into the mouth-piece were not audibly reproduced.
