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]'.
