Agrees with GS's assessment of Ernst Klinkerfüss's paper [see GS's 1866-2-27].
Comments further on Ernst Klinkerfüss's work [see JH's 1866-2-28]; on the behavior of light emitted by an electric spark.
Acknowledges receipt of paper on nebulae.
Comments on impossibility of increasing the intrinsic illumination of a source with a telescope; how to obtain the spectrum of red flames of the sun.
Believes that expensive telescope wanted by William Huggins is unnecessary for the intended purposes [see GS's 1867-5-3]; JH offers a telescope of his own to R.S.L.
Agrees reluctantly to write obituary notice of William Whewell; wishes he had been asked earlier.
Comments on the time needed by JH's son [John] to perform observations requested by R.S.L.; thanks for list of tutors [see GS's 1867-5-13].
Note accompanying JH's obituary notice of William Whewell.
Asks GS to explain to R.S.L. Council why JH's son John cannot appear at a meeting of the Council, as he is due to sail for India.
Does not know if equipment from R.S.L. reached JH's son John at Southampton [see GS's 1867-11-18].
Comments on JH's son's reports [see GS's 1868-11-6]; recalls idea of JH's father, William Herschel, about nature of solar light; transit of Mercury 'beautiful'.
Further comments on solar light [see GS's 1868-12-1].
Returns paper on musical scales; agrees with GS's comments on A. Prazmosky's paper [see GS's 1868-12-10].
Comments on a paper on the effects of lateral movement in diminishing the intensity of sound.
Requests sending of a copy of recent R.S.L. Proceedings to JH's son in India.
Note to accompany an extract from JH's son John's letter, reporting on his observations of solar prominences.
Agrees with GS's clarification of 'continuous spectra' and other terms [see GS's 1869-9-2]. Includes a copy of part of a letter from John Herschel [JH's son] about solar prominences.
On a correction to a report [JH's obituary on William Whewell].
Reports on paper [R.S.P.T., 159,. 575-] by [Thomas] Andrews on continuity of gaseous and liquid states of matter, believing it fit for publication.
Reports on Edward Sabine's paper [R.S.P.T., 154, 227-] comparing magnetic disturbances at Kew and Nertschinsk. Makes suggestion regarding period of solar spots and other matters, but deems paper worthy of publication.
