il occupied by large hardware store,
through which access is obtained 10 the spa.
cious lofts on the second and third floors.
Some weeks ago two unpretentious Germans,
Hector Krsus and Hermann Linde, rented
both these lofts, and carpenters were soon at
work putting up partitions Of common planned
boards and transforming the place into q
studio of very novel pattern, and intended
for very novel purpose. A steam engine OF
six horse power was put up in little engine
room, partitioned off in corner at the head
of the stairs; although in what manner two
German artists should require steam engine
puzzled the hardware dealers beneath them
exceedingly. The next procedure was 10 put
into operation an electrical generator, manu-
featured by Siemsns g. Holske, of Berlin,
whose armature, composed of botbin after
bobbin, laid parallel to its axis, revolved at
the rate of 1000 revolutions minute be.
tween two magnets. Conductors transferred
the current thus generated to an electric lamp.
ola strange and foreign pattern, furnished
with rack and pinion adjustments operating
with the precision of clockwork. This also
was from the mandatory of Siemens L.
Holske, and registered light of 2 900 candles.
The lamp was placed in the angle Of board
partition, into which, with their optical axes
at right angles to each ether, were two large
double-convex lenses at such respective dis.
tsnces from the voltac arc that their foi
met in the center of its intolerable blaze.
Each lens formed part of an ordinary camera
for photographing, whose adjustable body
was concealed by the partition.
BY means of either of these cameras the
light of the arc, and the image of any object
so placed as to intercept it, can be
transmitted to dark gallery, in the form of
long rectangular corridor, which is
the camera proper of the process
Of photographing on linen by electric
light, devised several years ago by an Aus
TRAN inventor named Winters, and describ.
ed by foreign scientific journals in the latter
part of 1877 rs one of the remarkable novel;
ties of the year. The process is styled limo.
grsphy, and its novelty consists, according
to scientific authorities, not in the mere
fact of taking an impression by electric ligh.,
but in the fact that the picture is a part of
the fabric of the cotton or linen canvas,
which may bo washed and ironed or sponged
with soap and water without impairing the
distinctness and beauty of the photograph.
In order to understand the process the OBJ
server must obtain admission to one of the
large cameras while the artist is at work. A
large screen, the surf ace Of which Is painted
white, slides backward and forward upon a
long trsmwsy, parallel with the axes of the
lens. A section Of canvass saturated in u
sensitive preparation is frst tackled to the
screen or easel, and the car upon which the
latter rests is pushed a'ong the tramway
until 1t Is 10, 20, 80, 40, 90 or even 100 fest
from the lens. A small photographers
negative-previously taken-of the person
or object to be transferred to the canvass is
then slipped into slot in such manner
that the axis Of the pencil of light trans
mitted by the lens passes through its
center.
These simple preparations completed, the
blaze of the arc il admitted: and, in the
course of one moments exposure the image
upon the negative has been indelibly printed
upon the canvas. Pictures of any desired
proportions, from one foot to fifty feet, may
be transferred in this manner from negatives
30 minute as to be mere specks to the unss-
sisted eye, and so perfect is the impression
that the meshes Of the lace, the texture Of
the velvet or silk, or even the most delicate
seamsin clothing of the finest fabric are re-
produced with the distinctness of nature.
The texture of the skin, the relative Hneness
of the hair, the crows feet at the corners of
the eyes are as sharply defined in the photo
graph as they are in the living subject. After
the impression has been taken the canvas is
thoroug hly washed and rinsed, then taken to
the studio and coverd with coating of wax,
so that the picture can be colored to life ii
desired, and the finishing touches of the
artist applied. Show cards, window shades,
stage scenes and the decoration of tapestries
are among tho applications Of this simple
and efficient method of Photographic print
ing.
