Gratified by JH's 'sympathy and approbation,' and that JH's writing and spirit remain 'firm' and 'fresh.'
Thanks for work on diamagnetism and magne-crystallic action [Researches on Diamagnetism (1870)], which JH is excited to read. Mentions long-abandoned plans for magnetization experiments. Envies those who can see JT's 'magic' experiments at Royal Institution.
Cannot attend Eclipse Committee meeting but suggests that an observer carefully look for planets interior to Mercury's orbit, which would, if existing, reach conjunction during total solar eclipses.
Regarding Alexander Herschel's paper on acoustical oscillations recently sent to G. A. Erman.
Would he accept a volume of observations carried out at the Leyton Observatory?
Has had a visit from Alick (JH's son Alexander) and his friends. Sends her latest photograph.
Of toads in rocks and stones, and martins in blocks of ice under rivers.
Writes about JH's health; justifies writing by sending some curves prepared by JH's son Alexander.
Is creeping along slowly like Alcuin's snail. Curvers are very curious. Informs him where there is an account of Coca. Comments on this as a tonic.
Received JH's note. TW's wife Amelia [Herschel] and baby fared poorly in Panama and California. China better now than in 1853-65. Constitution flimsy but still vital. Describes 'Mahometan insurrection.'
Continues to explain matters in perturbation theory. Stresses need for careful observations in solar eclipses. Doubts the existence of the hypothetical intermercurial planet Vulcan.
Admits his misstatement in RP's Other Worlds than Ours concerning perturbation of outer planets. Shares JH's doubts about existence of Vulcan. Speculates on the extent of meteoric material in the solar system. Comments negatively on J. Norman Lockyer's views on meteors.
