26 MAGIC LANTERN WITH DIRECT CURRENT [Cn. I abel SB U33JOS UQ *dn 3pis jnq }uud aq; puB Buuq HIM siqj, UIQJJ ABMB SUIDBJ si SUIOBJ puB dn 3q 'duiB[ os SB ui uo FIG. 8. STANDARD AMERICAN LANTERN SLIDE, FULL SIZE, WITH DIRECTIONS FOR MARKING IT, AND INSERTING IT IN THE CARRIER so THAT THE SCREEN IMAGE WILL BE ERECT. § 35. Correct position of the lantern slide in the carrier. — In order that the image on the screen may be right side up and like the original in every way, the lantern slide must be put into the carrier in the following manner to counterbalance the inverting effect of the projection objective (fig. i). 1 . A lantern slide with any printing upon it must have the side which reads correctly face the lamp, if the screen is of ordinary form. If the screen is translucent like ground glass and the picture is viewed from the back of the screen, then the printing must face the screen, not the lamp. 2. In all cases the slide must be put into the holder with the bottom edge up (fig. 6, 8).
