Description:
The wooden box, painted gray, contains two pairs of eyeglasses sealed in plastic bags (they appear to have polarizer lenses), two bags of small lenses, a mounted prism, an eyepiece, tourmaline tongs, a bracket, and a rectangular glass plate. The box has a hinged lid but a knob in the front, suggesting it was used as a drawer. A note on the front has been handwritten: "Ripple Tank / SLITS".
