ouse, to show sharp, well-illuminated lantern slide projections
without difficulty and at small expense.

The Kodiopticon is substantially made, and operated with an ordinary
Mazda electric lamp, at a distance of 10 feet from the sheet, will
project images of about 36 inches. A larger image may be secured by
setting the Kodiopticon a greater distance away, but the greater the
distance the less the illumination. Can also be furnished with an
electric arc lamp, when it can be used at 12 feet, with the maximum
illumination, projecting an image of about 42 inches.

The Kodiopticon has a water jacket for protection of the slides from
heat, and the price includes a strong wooden case, which, by reversing
the top, serves as a permanent stand for the outfit.

An interesting and highly enjoyable diversion for the amateur
photographer is the coloring of prints. And those who use the
Kodiopticon will find that many slides are greatly improved by the
addition of color. While actual color photography is by no means
practical for general amateur use, anyone can make beautifully colored
prints by the use of Velox Transparent Water Color Stamps.

No special artistic skill, no knowledge of painting whatever is
necessary. Just a brush or two and the book of stamps, which includes
simple direct
