Signaling Device Which Promises to BE
of Great Utility.
From the Electrical Review: The vir-
tues of an electric monogram signal
have already been referred to in these
columns. The device is sort of type
writer delivering it's message, letter by
letter, in midair, or at any distant point,
in gigantic characters Of light. The OBJ
servers may be miles away and yet
read the message with ease. The key
board is manipulated exactly as in an
ordinary typewriter and its function is
to switch n or direct the current
through a series of distributing wires,
which are carried in cable to the mon
ogram or display frame. According to
a predetermined scheme the keys eXer-
else a selective function, and each one
switches in the leading wires only,
which connect with the members OF the
monogram constituting the letter of the
alphabet which that particular key rep
resents. By reference to the monogram
one may easily trace any letter OF the
alphabet in form so nearly convention
al as to be readily understood. Thus, II
on the keyboard the A button is pressed
the lamps of all members of the mono
gram entering into that letter shine out
simultaneously, while all other lamps
upon the display frame remain dead.
And so on for every letter. The OBJ
server has only to follow the letters as
they flash out one after another to spell
out the words of the message. 1t will
be seen that this is sort of visual tele-
graph, and that it may be made to talk
in almost any language spoken by man.
It is also serviceable for cipher writing
according to any prearranged code. The
monogram frame is five feet high by
three and One-half feet wide and is
equipped with 16-candle power lamps.
Signals flashed from this frame are Wis
able to the naked eye for distances of
from one to three miles, depending on
the weather. With glass the signals
may be easily read UP to ten miles.
Some frames are made much larger and
can be seen further.
Its Possibility Not PrOved-Conclusion
Reached by Medical Writer.
An interesting article on the alleged
communicability of cancer of malignant
growth appears in the Medical Record.
1t says, in part.
From the time the malignancy of can
Ger was recognized the question OF COM
municability has borne the brunt OF
the most earnest investigation, and the
hope of it's solution has stimulated the
most ingenious experimentation OF
earnest Investigators The results of all
such studies have been entirely ne
gative. There are no proofs OF which
we have any knowledge that cancer has
ever been directly or indirectly prop
agated from one human being to
another 1t is true that there is pub
lished an occasional case in which there
would appear on superficial eXamina-
ton to be a direct relation between
cause and affect, but when such are
critically examined the theory of prop
agation vanishes in face of a conscien

are coincidental circumstances follow
ing the general law of accidents. Ex-
periments in the lower animals have
thus far amounted to nothing, and
practically we are as much in the dark
regarding the true etiology Of cancer
and it's real methods of dissemination
as ever.
The Investigations in these directions
have been exceedingly interesting,
although mostly instructive from ne
gative view.
A person predisposed to any disease
is always an easy victim when any def
mite, exciting cause presents itself, |
while one without such tendencies es-
capes every time.
The writer concludes by saying that
the death of physician of this city
from supposed incubation of cancer
was undoubtedly one of predisposition
to malignant disease that developed in
due time, the supposed incubation
from a cancerous patient having no
more causative relation to it than any
other purely coincidental circum-
