Messrs. Adams, Blodgett & Co. have sent

TO professional and business men, and which
Mr.. Bailey has under his charge These ma
chimes will be on exhibition only three DAYS.
They are very neat affairs compared with
the old cumbersome machines of ten years
ago. They ca be run either by a treadle or
electric motor. On small table, like a sew
ing machine, is placed a horizontal cylinder,
about five inches long by one and half OF
TWO inches In diameter, on which is placed
cylinder of dark wax-like composition. Lit
tie circular disks or frames about the size of
silver dollar, are adjusted so as to make
record of sounds upon the wax cylinder.
which in operation revolves at a fixed rate.
while the disk moves slowly along the sur
face of the cylinder, the result being the pro-
duction of record of the sounds taken in
minute lines Of indentation made spirally
around the same. To the left of the cylinder
Is small square box containing a small
electric motor to actuate it, the motor being

as desired, or the machine can be fitted to be
run by a water motor or by foot power. Two
or three little keys conveniently placed are
used to start, to stop, or to make the machine
repeat from any desirable point, as occasion
may require. The diaphragm, which is of
exceedingly thin glass, it should be stated. is
connected to the soft cylinder by a metallic
point or stylus, and according to the strength
and character of the vibrations produced by
the voice of the speaker are the indentations
made in the cylinder.
To operate, key is shifted ON the motor
box. and the cylinder begins to move with
steady, uniform motion A flexible tube
ending in mouthpiece is attached to this
diaphragm, and into this the operator talks
in an ordinary tone of voice. As he talks
the diaphragm vibrates, and the stylus af-
fixed to its under side makes lines of varying
depth and regularity on the cylinder. To
reproduce what has been recorded, the dia-
phragm is shifted back again to the begin.

The graphophone is simpler in construc-
ton. and is an Improvement on the phono-
graph. The reporters yesterday listened to
some fine instrumental music reproduced on
the photograph.
These instruments have become so indis-
pensable to lawyers and merchants that they
cannot do without them. They talk into the
machine all their correspondence, speeches.

sits down to the instrument, applies the
treadle or motor and takes off the whole
business in the very voice and words of the
employer. The North American Phonograph
Co., who own these machines, will sell 10000
