Part II' [not enclosed]. Professor [Walter Noel] Hartley's paper 'Note on Quantitative Spectra of Beryllium', would require about three pages of 'Proceedings [of the Royal Society]'. Rucker suggests it should be referred to Sir W Crookes. Mr C T R Wilson's paper 'On the Spontaneous Ionisation of Gases', is about six pages. Professor [Arthur William] Rucker accepted it and ordered the printing of it to be proceeded with. 2 November 1901
