Pendulum experiments to be conducted at stations of Great Indian Trigonometrical Survey.
Encloses description of Col. [J. T.?] Walker's experiments. Asks for JH's opinion of these.
Needs to make some adjustment about FW's visit to JH, as FW was not aware that Sunday trains in Britain run differently from other days.
