Letter from Charles H [Herbert] Lees, Osborne, Belgrave Road, Oldham, to [Joseph] Larmor The report in 'Nature' will not be detailed as Larmor imagines.

He would not have mentioned such a guarded expression in a more elaborate report. He gives two examples with sketches showing an inner and outer vessel.with calculations. 25 September 1900
