cogged persistence.
o. such is Mr. Frederick E Ives Of Pail
adelphin, who has, by his own account,
been working on this problem for almost
J o dozen years. He still belle yes

tue process BY wsica he had achieved
some few partial results, sad by which he
expects 10 accomplish much more. He

Two processes, he explained, are used
in Photographic colors Il enc ST them
the c9lor5 are produced directly by action
OF Light upon peculiar silver compound.
In the other the action OF light ueoa color
sensitive plstes is made to regulate the
distribution and combination CT cclors
which constitute the hasl picture. Bot
OF these methods have been made to
produce pictures ia Wiish colors have
been initiated in s general w.y. In regard
to his own process ne said:
IL consists Of making three negatives
On color-sensitiVe plates, which are ex-
posed simultaneously Ia g triple Gamers,
OebiLd light nl!srs that ore carefully ad

Whatever may be thought of the pros

seems to be Eo doubt that he has doxe
much toward demonstrating that "the
apostolic can be accomplished"
