The Great Exhibition, 1851: Heliostat and other Instruments by Dubosq-Soleil

Photograph showing a collection of instruments for exhibiting the phenomena of polarised light and other physical experiments. A saccharometer is displayed on the left, a heliostat in the centre, and a haloscope on the right. The objects were exhibited by Dubosq-Soleil at the Great Exhibition.

This photograph is from Volume II (RCIN 2800001) of ' Exhibition of the Works of Industry of All Nations, 1851: Reports by the Juries on the Subjects in the Thirty Classes into which the Exhibition was Divided'. The incredibly successful Exhibition of the Works of Industry of All Nations, commonly known as the Great Exhibition, ran from May to October 1851.  At the exhibition's conclusion, over 100 copies of the four volume 'Reports by the Juries' were distributed to foreign governments and notable participants. The reports consist of the juries' comments and assessments of the works displayed in the exhibition. The idea and decision to illustrate the reports with photographs is attributed to Prince Albert (1819-61).
