New Road | Hammersmith | 20 Octr. 1853
Dear Sir
I think you must refer to a little apparatus which by the position of a series of little ivory balls shews the progress of undulations & is intended to illustrate the wave theory of light. If so the one you saw probably belonged to the Revd. Robt. Walker2 of Oxford. There are others about town. I think that Newman 122 Regent St our instrument maker has one, if not he knows where they are. The apparatus has no reference to the water lines of ships that I am aware of[.]
