Many objects in Lord Rayleigh’s collection are annotated with a reference to the volume and page of his collected works where they are discussed.
Object 1930-506/2 has inscribed in pencil "II p 276" [difficult to read, may be different]
Object 1930-406/3 has a label attached (partly illegible) that includes reference to “II p 376”.
