Comments on WH's spectroscopic examination of cometary tails [see WH's 1868-7-2].
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.
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.
Thanks to WH for the photograph of solar protruberances; comments on polarization of light from the sun.
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.
