Henrici's harmonic analyser, No 3, 1894.

Harmonic analysers were designed to break down a complex wave, such as a sound wave, into its fundamental and harmonic components. This one, designed by Professor Olaus Henrici (1840-1918) and made by G Coradi, uses the motions of three glass spheres which turn numbered dials.
