method Of burning a ribbon OF magnesium
tape that has been used Tor a long time.
Before the meeting the young gentlemen
who don't know much about the business
and the gray boards who know ii all
stood about in little groups eXcitcdly dis
cussing the new invention.
The routine business was disposed If in
a hurry, and then DIR. PiiTard wa, intro
duced. He is a tall, well built gentle
a with a head of thick, wavy brown
hair, a heavy mustache and strongly
marked features. Liberal applause greeted
him. He read a short address on the
difficulties experienced in producing sue
cessfully an artificial light that would do
for taking pictures. He illustrated sew
eral Of the unsuccessful attempts that had
been made, and dwelt particularly upon
the failure of the magnesium ligl.. He
Lit a ribbon Of magnesium tape, and
showed how apt il was TO flare up and
then subside and suddenly TO go out be-
fore the picture was taken.
A big camera was rolled out into the
room, and a table, whose top came up
even with the lens, was placed beside it.
A brick was placed upon the table. and
upon this brick the doctor put about six
grains Of gun cotton, and sFrinkled over
it from ten to fifteen grains of magnc-
stun powder. \ chair was placed in
front Of the camera about Ten feet away.
and Mr.. Ii. j. Newton seated himself in
this chair. A wax taper WAS lii and
handed to Mr.. Newton. who held It clOSr
to his face. He was fn0 used IN this posi-
ton. and then the Ii hts were turned
down until the room vas dark. \ dry

the gas was turned up.
Mr.. Robert Ro0s, velt was photographed
in the same way. The pictures developed
in a feN minut -, and negatives were
handed around. Ehey were perfect,
and a burst Of applause greeted the eN-

All mannerc al dark places can he photo

woodland scores and dark caves. 1t will

pictures in their homes NJ night. and viii

incomes.
An entirely original use to which il can
be psf was referred to BY DR.. Piifard.
He explained that a small wad of the
compound could he placed in the barrel
of a pistol and exploded by conclusion.
He did this. and the flash was Just as
bright as when il was lgnitel in the loose
state. The idea Is the construction If a
small camera made 50 that il can be fast
ened to the barrel of a pistol. 1t is
claimed that the uses TO which this can
be put are manifold. Among them Is the

The fash is 50 quick that he will be given

chambers with bullets. When a burglar
appears. the citizen can point his revolver
toward him and take his photograph
first. The flash will enable him 90 see if
there is more than one burglar around.
