PAINTING THE SLIDES.

The slides containing the objects usually shown in a magic lantern,

are to be bought at opticians with the lantern, and can be procured

cheaper and better in this way than by any attempt at manufacturing

them. Should, however, the young optician wish to make a few slides of

objects of particular interest to himself, he may proceed as follows:

Draw first on paper the figures you wish to paint, lay it on the table,

and cover it over with a piece of glass of the above shape; now draw

the outlines with a fine camel’s hair pencil in black paint mixed with

varnish, and when this is dry fill up the other parts with the proper

colors, shading with bister also mixed with varnish. The transparent

colors are alone to be used in this kind of painting.
