Unidentified · Physics

Glass slides for the Multiple Image Projector (, contained inside a wooden box. The box has a hinged lid with two rotating hook latches to hold it closed. Inside the case, there are 15 glass slides which are approximately 12.5cm x 10cm in dimension. Each slide is stored vertically between two wooden notch cutouts in the side of the box; these are numbered along the edge. Tucked into the interior of the lid of the box there is a piece of cardboard which describes the content of each slide.

On Each separate slide, the transparent sections are different shapes or designs, but within each slide the transparent sections are the same or similar. Each slide has a sticker in the corner to number it, and another to label it or provide use information.
