Description | 'Dear Sir, May I remind you about the volume of the Poids et Mesures which we wrote for last July, & which you asked to be allowed to retain "for another month or two". The book has not yet come back to us, and as it is now the end of the year I take the opportunity of sending you this reminder. I am, faithfully yours, Robt Harrison Asst. Sec. R.S. [Assistant Secretary, Royal Society]'. |
