Has been occupied with the wedding of his daughter [Amelia], so unable to read his paper before. Comments on the various theories regarding the tail of the comet. Regrets his statements do not agree with those of WH.
Much obliged for his suggestions regarding the comet; comments on these suggestions. His own observations were made on the comet, not its tail. Would be pleased for him to visit his observatory when in London.
Comments on WH's finding the carbon line in WH's spectroscopic examinations of cometary tails.
A note to accompany JH's biographical sketch of William Dawes.
Sending a photograph of a solar prominence he has received from Major J. F. Tennant. Comments on various features. At the Transit of Mercury he saw the phenomenon described by J. H. Schröter.
Thanks to WH for the photograph of solar protruberances; comments on polarization of light from the sun.
Has arranged for the last R.A.S.M.N. to be sent to him. Lieut. John Herschel has detected a fourth line in the spectrum of the Nebula in Orion.
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].
