Note with return of proof of JH's biographical sketch [see WH's 1869-1-22] of William Dawes.
Comments on some incorrect attributions to JH.
Comments on the radiant heat of heavenly bodies and the motion of Sirius.
About an increase in sun spot activity.
Note to accompany the reported observations of JH's son John.
Thinks it would be best to send his son's letter to G. G. Stokes at the R.S.L. Cannot give a positive opinion on WH's plan for seeing the prominences. Finds some discrepancies in the Report of WH's paper on Sirius and the paper itself.
Suggests the planet Mercury may be a good subject for his spectroscopic experiments. Gives comments and explanations on his proposals. May like to communicate the results to the R.A.S.
Note to correct calculations in an earlier letter [see JH's 1869-9-20].
Burn his [last] letter as he made a blunder in his geometry. Cannot imagine how he made the blunder. Gives new formulae for observing Mercury.
