Copy letter from Robert William Frederick Harrison, to Messrs Longman & Company 'Dear Sirs, With reference to the enclosed post-card and letter from Mr Murbech of Detroit which you sent on to us and which I now return to your care, they do not relate to any paper or work communicated here, and the only suggestion I can make is that the matter may have some connection with the Royal Society of Canada, but I must leave you to elucidate the point. I am, Dear Sirs, faithfully yours, Robt [Robert] Harrison Asst. Sec. R.S. [Assistant Secretary, Royal Society]'. 23 January 1904
