History OF THE ELECTRIC TELEGRAPH. BY

| It's work which much wanted, as the inn
provements and extension of the electric telegraph
have become 60 great, of late years, to invest

the novelty which surrounds everything connected
| with them, and the wonderful results produced by
their operation, that the public mind can scarcely
realize their Importance.
The subtle fluid by which various ingenious ma
chimes are actunted, is remarkable in its nature

the structure and principles Of the different tele

| popular elementary work was demanded-one
embracing all the facts regarding the history of the
electric telegraph from its earliest conception up to
the present period. This desideratum tho author
has attempted to supply. He states, inhis preface,
that
Our aim has been to describe electricity and electric
tel.graphs in such popular form as to enable party
not previously and fully initiated to gain clearer and
better knowledge Of the subject.
The work, after preliminary remark, opens
with an interesting chronological table, of discoye-
ries relating to the electric telegraph, followed by
description Of terms and telegraph instruments, il
lustrated by neat wood engrayipgs. Then succeeds
a brief review Of contested legal claims between
Morse and friends, against other inventors, with
the trials and decisions had in the United States
courts The work also contains specimens of tele-
glaIh signal writing and printing, with chronicle
gc;! statement Of the years in which various tce-
graph lines erected in the United States. Another
| chapter contains valuable statistical Information
citing the expense of building. management,
ard working Of the lines. An interesting chaptcr
is devoted TO the connection Of the press with the
| electric telegraph, III which will be iound some
amusing anecdotes and incidents
The arfhor has suggested and inserted notices Of
| several Lew appicatiors at electricity. These he

After showing the application Of the electric tee-

concludes with history of foreign electric tele-
graphs. and especially ofheir extension over various
parts Of Europe. by which it appears that the united
length Of tie present telegraph lines in America and
