I am sending you Proceedings [of the Royal Society] Nos. 57 and 238 with a small account for them. They contain obituary notices of Mr P Barlow and Mr P.W. Barlow. The Royal Society has not published an obituary of Mr W.H. Barlow, but it is very probable that the Institution of Civil Engineers did so.
I am, Dear Sir, faithfully yours,
Robt [Robert] Harrison
Asst. Sec. R.S. [Assistant Secretary, Royal Society]'.
