\subsection{James Smith and his Musical Glasses}
\break

James Smith's Tutor for the Musical Glasses (1829) \footnote{Smith} describes the disadvantages of Franklin's \glassarmonica{}:

\begin{quote}
The Glasses of the Harmonica are very liable to break. The larger revolve with much greater velocity than the smaller; the foot is apt to tire in turning the machinery; when to this we add the high expense of the instrument, we need not be surprised that it never came into general use.\footnote{Smith, iv}
\end{quote}

Smith concludes by describing ``the old slow, expressive soul-subduing melodies of Scotland, Ireland, and Wales, performed upon them [the musical glasses] by a  player of taste and feeling'':

\begin{verse}
They come o'er the ear, like the sweet South,\\
That breathes upon a bank of violets,\\
Stealing, and giving odours.\\
\end{verse}
