content: J. B. F. Soleil presented a complex instrument to the Paris Academy of Sciences in 1839, boasting that it would produce all the experiments of diffraction and interference that might be included in a physics class of the period. This example seems to be a later form of that device. The “J. & A. Duboscq à Paris” inscription refers to Jules Duboscq and his son-in-law, Albert, who were in business together in the years 1879-1882.
