Sends a proof of JH's obituary of W. R. Dawes. The concluding part of the manuscript was mislaid; would he therefore re-write the missing portion. Hopes to attend Professor Alexander Herschel's lecture this evening.
Note with return of proof of JH's biographical sketch [see WH's 1869-1-22] of William Dawes.
Professor Joseph Winlock of Harvard agrees with all WH's observations of Nebula of Orion. The observations at Bishop's Observatory between 1844 and 1851 appear to be the work of W. R. Dawes. Comments on the reasons why the bright lines are so easily seen.
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.
Has written to Lieut. John Herschel suggesting points on which solar observations might be valuable. Is pleased he has seen the bright lines. Saw some bright lines in the middle of the sun's disk.
Note to accompany the reported observations of JH's son John.
Would like his advice on how to publicize Lieut. John Herschel's letter; shall he send it to G. G. Stokes? Comments on the method for viewing the forms of prominences.
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.
Has sent Lieut. John Herschel's letter to G. G. Stokes. Gives reasons for the discrepancies in the report of his paper and the paper itself. Is wondering whether to set up his large telescope further from London.
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].
Unable to make any observations at the moment as his observatory is being enlarged to receive his new large telescope. Thinks it would be a good idea to carry out observations on Mercury. Is not sorry to be able to rest his eyes from his trying spectrum experiments.
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.
Is much obliged for the more correct determination of Mercury. As soon as he gets his new apparatus he will try to obtain observations of the planet.
