On a correction to a report [JH's obituary on William Whewell].
Feels that he has been quoted out of context, making it appear that JH favors the introduction of the metric system in India. This being not the case, JH then proceeds to show how the British system of measures is related to terrestrial measurements, especially the length of the earth's polar axis. In so doing, JH argues for the greater accuracy in the definition of the British units, as compared to the metric.
Comments on GA's theory of the thermo-electric origin of terrestrial magnetism.
About some flowers, including a new variety being advertised.
Deals with several problems related to several papers.
EQ may forward packages for JH to [John] Stewart in London. Discusses [James] Grahame. Pleased EQ liked his translation of the Iliad.
Is very pleased with resolution about the observations of Charles Rümker [see Edward Sabine's 1867-8-30].
Thanks WS for describing Aristotle's and Richard Whately's observation of the great sensitivity of the eye's lateral portion. Congratulates WS on becoming Dean of Norwich. Draft discusses miracles and lists possible arguments against WS's idea that miracles are not a violation of nature
Is assisting in communication between G. G. Stokes and GA, about stereoscopic observation of eclipses; JH is not mobile enough to attend the next Board of Visitors meeting.
A note with G. G. Stokes' letter, which JH forgot to enclose [see JH's 1867-5-5].
Ashamed not to have written sooner. Has received AQ's meteorology of Belgium. Wishes success with his work on social physics. Enjoyed AQ's Histoire des sciences mathématique et physique chez les belges. Disgusted that the French insist Isaac Newton stole his ideas on the system of gravitation from Blaise Pascal. Hopes to send AQ his 'synopsis of all micrometrical measures' made by William Herschel on double stars. Sends Latin version of Friedrich Schiller's 'Spaziergang.'
Believes Michael Faraday's boro-silicate of lead has not been used for telescopes, but JH and others have tried using it for other optical purposes. Describes method for producing veinless flint glass.
In response to RH's 1867-10-28, JH sends a list of his writings on astronomy.
Requests observations of Eta Argus. Margaret Herschel travels on the continent. Liberal Party under William Gladstone unsuccessful with reforms.
Sends a correction for the ninth edition of JH's Outlines Astr.
News of the forthcoming marriage of his daughter. Everyone seems to be mad on making ice.
It appears that the Indian government has now approved the introduction of the metric system; JH is very upset.
Writes to inquire as to the exact definition of the gallon and the pound, and the circumstances under which the appropriate measures would be made.
Is still trying to bring the various definitions of the pound into agreement [see GA's 1867-11-30]; the question of weighing in air or vacuum remains as a problem.
Having helped to create confusion surrounding the pound weight [see GA's 1867-12-3], JH now understands it simply and clearly; JH wonders if he is 'growing elderly.'
