FREDERICK E. IVES, of colour photography fame, SAID in a recent address
In my opinion the best of these inside-lantern Saturators yet produced is that of
Perken, Son, and Rayment, of London. . . . It will not become unduly heated
in the lantern, as some of the others might, and is a model of compactness and
convenience. I think so much of it that I have adopted it for my own use."

PREFACE,
SOME few months ago the writer was arranging a limelight
apparatus for advertising purposes, and was anxious to get a book
at a moderate price to place in the hands of the man, ignorant till
then of everything connected with the lantern, who was to
work it. None of the existing books fulfilled his requirements,
being either too elaborate on the one hand, or on the other,
while suitable in most respects, limited to the goods of some one
firm of manufacturers. A similar want being felt again a few
weeks afterwards, this little book was put in hand, in the hope
that it might be of use to others in a similar predicament.
It has been written on the assumption that the reader at the
outset knows nothing of the lantern or its technology ; terms that
he would not otherwise understand have therefore been explained:
.and the illustrations have been selected to show the principles
upon which the various pieces of apparatus work, rather than
the mere external appearance of any particular maker's product.
It should be hardly necessary to point out that it contains
nothing that is not to be most probably found elsewhere, somewhere
or other, but care has been taken to point out those
cases where the author is unable to speak from his own
experience.
It only remains for him to express his thanks to those firms to
whom he is indebted for the loan of cuts of special forms of
apparatus, and to Mr. R. R. Beard, who has been kind enough
to give him the aid of his great practical knowledge of the
limelight.
