bells can be adjusted by having the
cores to and from the armature: the
bells should almost touch the ham
mer. The receiver can he adjusted
by putting the magnet nearer or
farther from the sheet OF iron. The
transmitters can most OF them he adj

on the diaphragm. To understand
the working Of telephone it Il nee
essary to remember that current Of
electricity passing through a coil OF
insulated wire will make magnet Of
a piece OF iron placed in the coil; if
this iron Is soft it viii lose its magnet

4 current OF electricity in the coil
which alternates the impulse travel

magnetized and the other direction
when tits no, magnetized. and 4 coil Of

current. Most phones are 20 wired
that the battery wires connect with
the main line 50 that If the current is
too strong the line acts as sort of
overflow. A dry cell can be used
