Copy letter from Robert William Frederick Harrison, to H W Simpson, Royal Geographical Society 'Dear Sir, I have enquired both of Sir Archibald Geikie and of the Assistant Librarian, through whose hands the Antarctic printing work passes, but regret to say that I have not been able to come upon any trace of the two negatives which you inform me were last placed in the hands of Mr Bernacchi. No such negatives have been returned by him here. I am, faithfully yours, Robert Harrison Assistant Secretary R.S. [Royal Society]'. 15 October 1907
