Copy letter from Herbert Rix, to The Superintendent, Standards Department, Old Palace Yard, S.W. 'Sir, With reference to the request orally conveyed by Mr J Milsted Spencer when he called here a short time since, that the return of the Standard Yard and Pound might be deferred for the present until Professor Mandeleeff's return from Paris, I have the honour to inform you that the President and Council have no objection to offer ^to this cause^ but that they are of opinion that the measures should be returned here before the 28th July at the latest, as I shall be leaving town about that time. I am, your obedient servant, H Rix Asst. Sec. R.S. [Assistant Secretary, Royal Society]'. 26 June 1894
