"MUSIC BY TELEGRAPH.

"A most interesting field for the musical student is the
progress that is being made in _telegraphing musical
sounds_.

"This is done by means of the telephone, which transmits
simultaneously several different tones through one wire by
means of steel forks made to vibrate at one end of the line,
the pulsations passing through the wire independently of
each other, and reappearing at the distant station on
vibrating reeds.

"Some very interesting tests were made in the Centennial
Main Building a few days ago in the presence of about fifty
invited guests, among whom were noticed the Emperor and
Empress of Brazil, Sir William Thompson, and quite a number
of eminent electricians.

"The experiments were of a very interesting and successful
character.

"The inventor, Mr. Gray of Chicago, asked his assistant, Mr.
Goodridge, to transmit musical sounds, which were received
very distinctly amid hearty applause from those present.

"It was the first time that many present had heard 'Home,
Sweet Home,' 'My Country, 'tis of Thee,' or 'Old Hundred,'
rendered so beautifully by telegraph; and they evidently
enjoyed the treat."

By this invention, music played upon a piano-forte or melodeon is
reproduced upon a violin attached to the receiving end of the wire at
a distance of twenty-four hundred miles.

Another important musical invention (English) is that of the "voice
harmonium." Of this Mr. Theo. T. Seward writes,--

"To all such the invention of which I speak is a matter of
deep interest, because in it is practically solved the
problem of perfect intonation. It is called the 'voice
harmonium,' because the securing of perfect intonation
brings the tones much nearer to the quality of the human
voice. The instrument has been invented and patented by Mr.
Colin Brown of Glasgow, Ewing lecturer on music. By the use
of additional reeds and a most ingenious keyboard, he has
succeeded in giving each key in _perfect_ tune. The 'wolf'
is banished altogether, without the privilege of a single
growl. I do not need to say that the effect upon the ear is
rich, and extremely satisfactory. After listening to it a
little while, the tones of a tempered organ sound coarse and
harsh. I wish very much that s
