Is puzzled by two apparent contradictions in JH's recent book Familiar Lectures. Are they printer's errors? Was related by marriage with the late Sir John William Lubbock.

Invite JH to give lecture series at Literary and Philosophical Society next winter.
Preparing for total eclipse of sun in 1868. Conferred with William Huggins about making spectroscopic analysis of red protuberances. Asks JH's opinion.
Asks JH's opinion on matter of purchase of expensive telescope for solar eclipse (1868) and other observations by William Huggins.
Is uncertain if he has detected the lightlines on the solar surface to which JH has called attention, but there does seem to be something unusual there. No sun spots are visible just now.
His brother [John H. Nelson] is at Brighton, and may be coming to London soon. Bodily health improves but mental health shows no improvement.
Response to a letter from JH to G. G. Stokes [1867-5-5] seen by GA, on the problem of the effect of the telescope on illumination from a light source, especially related to a solar eclipse.
Comments on the use of different telescopes and their effect on the albedo of the sun, related to solar eclipses [see JH's 1867-5-5].
Returns JH's letter from G. G. Stokes about eclipse spectroscopy; GA has written to Stokes as well and encloses a copy of this letter.
Sends a pamphlet by a friend of his, Mr. Thornton, on the squaring of the circle; would like JH's opinion on this pamphlet.
Regrets he was out when JH's son called, but has sent him a card for Saturday. Pleased to hear that JH supports RM over his David Livingstone appeal. Suspects that Livingstone will turn up after a year.
Please accept his grateful thanks for his comments on Mr. Thornton's squaring of the circle. Will send these comments on to Thornton.
The theorem is one of the consequences of the Julius Plücker system. Comments on JH's proposed method.
Sends list of tutors at Trinity College contemporary with William Whewell; comments on telescope needed for eclipse viewing.
Outlining a series of experiments based on JH's work on Light.
Read JH's letter to his brother and it did not seem to affect him one way or another. Mental health is no better.
Will not apply to government for money to purchase telescope for observing [1868] eclipse. William Huggins believes that larger telescope is needed. Would JH's son [John] make these observations [for R.S.L.]?
[Form letter] At governor's request, sends JH copy of 'Trigonometrical Survey of Southeast Coast of this Colony, by Captain W. Bailey, R.E.'
His collection of poetry has made good progress. Outlines the proposed contents of his book. Has not thought of including Latin compositions.
Wrote to G. G. Stokes and agreed to seek the permission requested by R.S.L. Will arrange for personal interview with Stokes. Is this 'independent of [Charles] Tennant's proposal'? Outlines survey plans if given charge of large instrument.
