Prof. Cooks suggestions seem credible.
Such experiences as he describes as
common to the lady doctors would be
generally derided or attributed to a too
vivid imagination by the materialistic
scientist who must be able to
everything for himself before putting it
on the list Of facts to be recorded and
classified. 70 such Prof. Preece would
be able to give a more certain demon
stration than the psychic medium, but
the formers discovery makes the lat
ter's experiences at least seem possible.
A writer in the Spectator says:
Mr.. w. III. Preece, chef engineer
and electrician to the postofice has put
up a wire a mile long on the coast near
LavernOck, and a shorter wire on Flat
holm, a little island three miles off in
the British channel. He fitted the lat
ter wire with a tsounder' to receive
messages and sent a message through
the former from a powerful telephone
generator. That message on the main
a was distinctly heard on the island,
though nothing connected the two, or,
IN other words, the possibility of q tel
ephone between places unconnected by
wire was c%onclusively established.
why, In fact, II n wire can talk to
another without connection save
through ether, should not mind talk to
mind without any wire at all? None Of
us understands accurately, or even as
yet approximately, what the conditions
are; but many Of us know for certain
that they occasionally, and by what we
call accident, have been present to par
ticular individuals, and that, when pres
ent, the communication is completed
without cables, and mind speaks to
mind independently OF any machinery
mo- existing within ITSELF"
PhotoSraDhing Letters by Te1e-
graph. N
Prof. Jacques is said to be of the
opinion that letters can be photo
graphed by telegraph by the use of a
comparatively simple apparatus. He
has frequently sent photographs over
the wire. His laboratory consisted of
only two rooms, In n Of which was
an ordinary Photographic camera u
small developing closet and a small
cubical box, in one side of which was
a slit OF sufficient size to receive n post
al card. From this box, which was
placed on a table In the middle of the
room, two wires stretched across to d
partition wall and passed through this
to a similar cubical box standing on
a table In the middle Of the adjoining
room. If it is desired to transmit a
message on an ordinary postal card,
the note is inscribed and then placed
about six inches in front of the camera,
where it is brightly Illuminated by an
electric lamp. The button of the cam
era is then pressed, and the operator
takes the plate holder to the develop
ing closet, and soon reappears with a
hastily. made negative, which he drops
into the slit of the cubical box on the
table in the middle of the room. On
| going into the adjoining room the D
ator finds issuing from the correspond
ing box on the table in the middle of
the room a thin piece of paper the size
| of q postal card, upon which the note
is reproduced in it's entirety. Prof.
| jacques holds that the sending and re-
ceiving boxes, instead of being in ad-
| joining rooms, will effect just the same
| results if one is placed, properly con-
nected, in Boston, and the other in New
| York, and in this case letters written
in one city can be instantaneously pho
| tographed to the other and beat the
mails by several hours.
An Electric Deck Planer.
A distinct advance has been made
on hand work, SO far, ut all events, as
regards time, in the introduction of the
electric deck planer, which relieves
the men Of a very d~isagreeable task,
as deck planning by hand involves kneel-
ing OF sitting on the deck in q most un-
comfortable position. This tool, which
resembles an ordinary lawn-mower, like
| which it is worked, is the invention of
a Scotch electrical engineer. A steel
| plate is mounted On rollers, and to the
under side of this the revolving cutter
| is attached, while the electric motor is
| placed on the top and geared to the
| cutter by spur wheels, which are COW
cred by an iron gnard. The front roller
is of the same length as the cutter,
| so that in passing oyer the deck 1t lies
On the crests of the uneven parts and
keeps the machine practically level.
| The hind rollers are set in so that they
| follow in the wake of the cutter. The

| speed OF 5000 revolutions per minute.
The machine works so quickly and SO
smoothly that it is said to be much
in favor with the workmen. All that
# requires is the labor Of drawing
It along the deck; The current Is
brought to the motor by light flexible
conductors.
Converting Incandercent Lamps
Into Geissler Tubes.
Quite a number OF beautiful and
varied luminous effects may be OBJ
tanned with very little labor by the use
Of lamps Of different manufacture that
have been converted into Geissler tubes.
A simple method OF, effecting this con-
! version is given by p. NJ. La Bordeaux:
"A burned out lamp, and IL possible,
one In which a piece Of the flament
has been broken off, should be pro-
cured, and the ends left separated
about an inch. To each terminal Of the
lamp a piece of wire should be soldered
and connected to the secondary termin-
ais of an induction coil yielding about
a one-eigth inch spark The globe
should be held in one hand and the coil
started, and the glass point where the
lamp has been sealed must be rubbed
off with a fine file and gentle pressure.
The filing should be continued until the
discharge diffuses the bulb, and then
the point is quickly sealed in the fame.
The object Of course, in filing the point
is to allow q certain amount OF mir to
enter the globe, producing a low
vacuum, through which the discharge
