them sing true, to put them in tune? Two or three of
them are naturally in tune. Some few, by great care and exactness, may
be brought very nearly into tune. But all the others were not, are not,
and will not be in tune, either individually, or with each other, or
with the instruments, or with the leader of the orchestra, or with the
rhythm, or with the harmony, or with the accent, or with the expression,
or with the pitch, or with the language, or with anything resembling
precision and good sense.

Delsarte has made it especially easy to tune the piano, by means of an
instrument that he calls the phonopticon, which it would take too long
to describe here. Suffice it to say, that it contains an index-hand
that marks the exact instant when two or more strings are in perfect
unison. It may be added that the invariable result is so absolutely
correct, no matter who may try it or under what conditions, that the
most practiced ear could not possibly attain to similar perfection.
Acousticians should not fail to examine this invention at once, the use
of which cannot be long in becoming universal.
