Postscript to a letter from [Ernest Rutherford], to [Joseph Larmor] 'P.S. I suppose it would be expected to take up the duties of the chair next October? I am not quite certain of the length of notice required by the authorities here'. Appended to MS/603/9/223, but belonging to the period leading up to Rutherford's transfer to Cambridge from Manchester; therefore likely a postscript to an early 1919 letter. [1919]
