content: This container with brass sides and glass ends, supported on a brass stand, shows that different liquids refract light in different ways. When the glass ends are set to different angles, it shows that the angle of deviation increases with the refracting angle of the prism. The “Lerebours et Secretan” inscription refers to an instrument firm that was in business in Paris from 1845 to 1862.
