Copy letter from Robert William Frederick Harrison, to Professor Arthur William Rucker, Secretary, Royal Society As soon as Harrison received Rucker's letter he took up the correspondence and found that in their letter of the 24th July enclosing the programme of the Wiesbaden Conference, the Prussian Academy said that definite notice of the place and time of the meeting would be directed to the delegates. Harrison has heard nothing since and has therefore written to the Secretary of the Academy for information by return of post. Is writing to Sir Michael Foster and Professor [Henry Edward] Armstrong as Harrison suggested. 30 September 1899
