Black microscope with wooden case, tin, two pieces of glass, key, mirror. Used to measure refractive index of liquids (and gases?). Water or oil, heated at a specific temperature (usually 25 degrees Celsius in chemistry and physics), is circulated from an external bath through the rubber tube into the glass prism and through the cell. The refractive index is measured against the temperature of the water/ oil and angle of refraction.
