                   "Cambridge Scientific Instument Company" and NOT
                   Kohl. Not found in Cambridge Catalogue  1913 (http

                   Instrument for the recombination of parts of the
                   solar spectrum.  I agree. The label on the
                   instrument in the new, clearer photo, shows that
                   this is made by Cambridge  Scientific Instrument
                   Company and not by max Kohl as Muensterberg’s list
                   indicates.   I  have not found this item in any of
                   Cambridge Scientific Instrument Catalogues,
                   however.  Unfortunately the catalogue in the
                   Smithsonian collection that may have it is not yet
                   available. Comment III: The apparatus I had had
                   identified as Nr. 81, Apparatus for reconstituting
                   the solar spectrum is not. It is M 91 Galton's
                   Apparatus for testing keenness of eyesight. It is
                   described and illustrated in Francis Galton, On
                   the Anthropometric Laboratory at the Late
                   International Health Exhibition. The Journal of
                   the Anthropological Institute of Great Britain and
                   Ireland, Vol. 14. (1885), pp. 205-221. [http://gal

                   The device is described in Cambridge Scientific
                   Instrument Co. 1883 [corr.: 1887] catalogue. It is
                   the earlier form of the apparatus and not the
                   updated version described in Cambridge Scientific
