Sends by book post two photographs of the original drawings of the sun's observations, also a photograph of a model of the S.E. portion of the moon; comments on them. Will be pleased to accept JH's invitation to visit Collingwood.
Thanks JH upon receiving the essay for the Leeds Astronomical Society lecture series ['The Yard, the Pendulum, and the Metre, Considered in Reference to the Choice of a Standard of Length'].
Is co-editor of a new quarterly scientific journal [Quarterly Journal of Science] and would be pleased to receive any contributions from JH, which would be liberally paid for.
Leeds Astronomical Society will publish the essay written by JH for their lecture series after its presentation. WT will forward the proof for JH's corrections.
Concerning the 'Standards.'
Regarding A. R. Clarke's paper on Geodesy. Benjamin Peirce's Lunar Table. The sun's parallax. JH's nebulae catalogue. Regarding the English inch.
Is still not happy with the earth's axis as a source of standard length; sends JH the results of A. R. Clarke's calculations on the figure of the earth [see JH's 1863-10-8].
Points out minor errors in the manuscript of JH's 'The Yard, the Pendulum, and the Metre.'
Thanks for his comments on his memoir. Sends a few additions, which he will be submitting to the R.A.S. in due course. Will send a copy of the memoir to JH's son.
Sees that JH mentions 'the longitude of perihelion on the ecliptic' as one of the elements he would like to have in the case of the small planets. Would like his advice.
Informs JH that his photographs of the moon's surface and diagrams of the sun's envelope were sent to the engraver.
Notes reception of corrections to JH's 'The Yard, the Pendulum, and the Metre.' Will send JH 100 copies of the essay.
Is very grateful for his work on the plurality of worlds. Comments on his own recent work and the work of JH on nebulae.
Comments on JH's advice regarding the 'longitude of perihelion in the ecliptic.'
Fine weather is getting rare at this time of year and would therefore like to induce the Herschels to visit him while it lasts.
Explaining some of the signs in the enclosed table. Has sent the Nautical Almanac for 1867.
WC's goals in founding Quarterly Journal of Science. Invites JH to submit article for first issue.
Announces JH's essay, 'The Yard, the Pendulum, and the Metre' will be read to the Leeds Astronomical Society on 10 Oct. 1863.
Regrets that JH's engagements prevent them visiting Penshurst. JN too is unable to manage the dates quoted. Hopes his own Herschelian helioscope will be in action by the time the Herschels visit Penshurst.
