Giving observations of a new star observed by him and some of his correspondents.
Much obliged for his observations of June 1842. Probably the same star that is now being observed. Gives observations sent him by G. B. Airy.
Has just found that the bands of light from the comet are resolved by the spectroscope into bands that constitute a modified form of carbon. The spectrum of the comet was compared directly with a current of olefiant gas.
Is grateful for his note. Has sent a paper to the R.S.L. on cometary phenomena and encloses a copy of the part in which he refers to JH's views. Would be glad if it were possible to explain the phenomena of tails.
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.
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.
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.
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.
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.
