VIEWS OF SCIENTIFIC MEN ON DR.
SELLE'S INVENTION.

THE SAME RESULT.

THE SAME RESULT.
For many years in this and other countries "a.
vanced students in the art OF photography have
been devotng their efforts and energies to the solu.
tIon of the problem Of producing instantaneous
photographs in colors. Experiments In this direo
ton have not met with any great degree Of sue.
cess until few days ago. according to dispatch
from the Berlin correspondent OF The Journal"
when Or. selle. Of Brandenburg. succeeded Ia
contrivng a Photographic instrument which
vii, in minute details reproduce the various colors
NJ objects persons and landscapes brought within
n specified range Of the camera Large numbers
of these photographs have been submitted 10 ex.
perts in Germany, and have been commented upon
with uaoualihed praise and enthusiasm The In.
yentor. however keeps the most important factors
OF mis- invention a secret All tnat ne VIII admit
is that his instrument contains three thin geatins
films placed at equal distances OF when all three
receive the same impressions OF the OBJECTS within
tho range of the camera with THIS distlhcloi tnat

second Of the blue. and on the thrd the yeiiow are
received He also comedies that indigo colors de-

,hich causes Illuminated spots TO assume tne de-

covered his lens the films are pressed toseuer ana
are then ready for development ana re,ouchinS.
