Copy letter from Michael Foster, to Professor Thomas George Bonney, Fellow of the Royal Society 'Dear Bonney, Would you kindly advise me how to reply to this letter. If any time you here, you will ask Mr Rix he will show you the maps of which he speaks, his former letter and my reply written by advice of Green. It seemed hardly worth while copying them to send you. Yours truly (signed) M. Foster Sec. R.S. [Secretary, Royal Society]'. 2 December 1895
