Paulsen, until few years ago, was an en-
p"yee 1.-The engineering department ~ the Coprn-
hagen Telephone Company. Naturally lac had
many facilities for experiment, bu, his associates
did not know what he was about Instead Of

The only reason why experiment, IA tins Il Irrr.
ton met with failure was hrrausc 1t involved
too much trouble To record the message ON tho
wax cylinder. The feasibility seemed apparent
enough. but until Paulscn appeared no value
could be attached 10 the cNpcr imcnts Thryuuug

The apparatus u CONSTRUCTED 81 that very
small magnetic needle which Is connected with
IN" current ~ tho telephone wire influences u
steel ribbon which In turn runs over woryhndrrs.
These cylinders come IN touch With H." may

Is influenced by the electric needle To- such Grlrrco
that perfect message Is recorded. AZ The re-

current will then reproduce the words sent over
the wire. Just az soon as tho message has been
heard by passing magnet over the steel ribbon,
the speech is wiped oil Immediately and the in
