Thanks JH for drawing of solar maculae from 1854-61. Some hesitancy about the accuracy of [Alexander?] Wilson's observations and hypotheses. Sixty people wish to travel to Spain to see eclipse of the sun.
Is sending solar autographs. Notes that in groups of spots the larger precede the smaller spots. Can JH form any theories from this?
Detached postscript that discusses the margins of the two photographs, which seem to show that all planets are in the near hemisphere.
Desires permission to present JH's 'diagram of "macularity"' to the R.A.S.
Discusses the different strata of the ocean and [William] Carpenter's lecture on deep sea dredging. Is digging an artesian well.
Sends two copies of JH's 'macular conspectus.' Mr. Titterton was very pleased that JH approved of his work.
Thanks JH for the drawings. Will send new solar autographs showing macula. Is working on the autographic series of the activity of the sun during its 11 year period.
Has been trying to make pendulum curves. Believes they may help explain the different sunspot forms. Thanks JH for the spectroscopic observation memoirs.
