upon their surfaces. While passing over
the non-conducting fluid on the foil, the
transmitting arm broke the circuit. As long
as the current was closed, however, the re-

was broken the upper retained its normal

done by clockwork without causing serious
error.
A modern patent, given to Patrick De-
laney of New York city,is somewhat similar
in principle. He employs as a transm!tter
a wide comb of metal, under which a plate
also of metal may be drawn back and forth.
A single electric wire closes a circuit be-
tween this and a similar contrvance, con-
stituting the receiver. The illustration 10
he transmitted is drawn in non-conducting
ink upon a sheet of paper placed between
the first comb and the underlying plate.
Chemical paper likewise rests beneath the
receiving comb. BY complicated arrange
nent the current is dispatched through the
teeth of the combs, one at a time, but in
such rapid succession as to appear instan-
taneous. The result upon the chemical pa

An exceedingly simple system of tele-
graphing illustrations by means of an ordi-
nary key and sounder was patented a few
months ago. it is for the use of any tel
egrapher who knows his alphabet. The re-
ceiver and transmitter each has before him
a diagram, consisting of series Of rulings,
running up and down and from left to
right, intersecting so as to form small
squares. The perpendicular lines are
Z = ei N on nd
bottom margins. The horizontal lines are
lettered "A, b, c, ID, E, etc." in the right
and left margins. The original drawing is
made, as large as possible, by an artist
upon one of these diagrams.
Ii is then telegraphed to the receiver
merely by naming in order the points of in
tersection Of the various cross-lines of the
diagram and the marks of the artist. For
instance, the outlines of a face might be
telegraphed thus: "R3-P7-L5-H2" and so
on until the whole outline drawing is de-
scribed. The larger curves may be made in
this manner, since all curves in reality are
made up of many straight lines. Definite
curves, however, may he indicated by addi-
tional signs A brief message describes the
nnlshlng OF the portrait. as. for instance
the quality of the hair, the style of cloth
ing, etc, to be filled in between the out
lines.
The receiver hands the telegram to an
other artist, who traces the portrait or fig
ure upon a duplicate diagram by simply
running the pencil over the surface between
the points indicated as the transactions of
the proper CROSSINGS. The picture is lastly
touched up in ink and handed to the edi-
tor. If 1T be for journalistic publication

The possibilities of an adaptation of long
distance image-transmission to the kinefo-
scope or Vltascope principles are by no
means more discouraging. Then, indeed
we might witness our base ball games as
they really occur and while they are in pro-
gress. But in anticipating what we might
