No. 9. Hall's Educational Stereopticon. No. 9 represents a Photograph of the Instrument. It is made of mahogany, beautifully constructed, and good proportions. The lantern case is twenty-five inches long (including the tongue for the front lens to slide on), twelve high, eight wide, fastened on the lever board with hinges, so it can be elevated to any desired point, and held there by means of the brass quadrants. The con- densers consist of two lenses fitted in brass tubes ; the front lenses consist of the very finest achromatic magnifying lenses, two inches diameter, fitted with coarse and fine adjustments. This lantern is so constructed that different pieces of apparatus can be interposed between the condenser in the front lens, such as Prisms, Polari- scopes, Magnetic Needles, Decomposition Tubes, and Animalculae Tanks ; also Photographs of Maps and Drawings, &c. These can be designated by means of a long needle, placed on the partition of the slide when in front of the condenser, and it will be shown on the screen. This saves the operator from going to the screen,
