THE SOAPBOXTICON.
We have received numerous letters from correspondents about the Soapboxticon. Some report great success in making it, while others have been unable to make it work right. To the unsuccessful ones we would say that you probably do not remove your lens box far enough from the muslin screen, your outer box not being quite long enough. In this case, you can move the lens box out of the other box as far back as you please. The lens we use is about two and a half inches in diameter, but the size is of little consequence. The main conditions are to keep the light well to one side, that no direct rays pass through the lens to illuminate the screen, and to concentrate as bright a light as possible on the picture, and on that alone. There should be no other light in the room when the experiment is tried, and the picture should be very clear and distinct. Two double convex lenses placed one at each end of a tube of card-board will act better than one lens alone.
