Sends a circular and JH's response to it for possible publication.
Wants to send JH's reply to the circular [see JH's 1864-9-6] to the author of the circular, and allow him to reply.
Apologizes for not having answered earlier. JH's health has been 'indifferent.' Received 'Sur un Problème curieux de Magnetisme' yesterday. Discusses 'alleged free suspension of Mahomet's coffin.' Agrees with JP that 'establishment of a stable equilibrium under the influence of mere magnetic forces is impossible.' Elaborates on an experiment relating to the 'problem.' Lists the works by JP that he has.
Outlines disadvantages of establishing a gold currency in India.
Regrets 'stupidity' of Italian post office, which lost note sent to JH suggesting reprinting of passage from Treatise Astr. of 1833 on operations of sun in second edition of JT's book. Also wants to publish JT's 'extremely philosophical views' on muscle contraction.
Thanks JH for advice on the pursuit of astronomy, especially concerning the importance of mathematics. Desires to know astronomy not just as a 'pleasurable companion' but as a 'bosom friend.'
Asks for information on William Herschel.
Regarding the opposition to the proposed introduction of the French Metrical system.H
Daughter has returned from Switzerland.
Thanking him for his letter to the Times [apparently on freedom of religious opinion].
Is very upset that JH's name has been attached to a group that wishes to import the 'French metrical system' into Britain; JH urges petitions or whatever is needed to retain the British system.
Is returning JH's paper on 'solar spots.' Comments on George Wilson of Glasgow and his suggestions on the use of telescopes. Encloses copy of a letter on the Moon's rotation. Was pleased to see JH's letter in the Times on the agreement between Scripture and Science.
Has just returned from a short tour of Russia. Visited Pulkowa and Nijny Novgorod. Had difficulties with couriers. JH's suggestion for a rotating disc with slit to reduce sunlight sounds feasible. Weather was unsuitable at Pulkowa for any observations.
Regarding the antiquity of the + and - signs. Origin of quid vides.
On algebraic signs, riddles, and the state of JH's health.
Hears that JH sits in his study with a stove. This is unhealthy for anyone with bronchial tendencies.
JH expressed himself with great precision in the old Discourses. Concerning one of the publications of the B.A.A.S.
Thanks JS for JS's speech. Discusses in detail JS's views on the introduction of a gold currency into India. Believes that this is a necessity and explains why. Notes problems and advantages involved in the circulation of money based on two standards, silver and gold.
Since writing JH's 1864-9-5 on JS's ideas regarding the introduction of a gold standard for India, JH has learned that 'the Sovereign is to be circulated at 10 Rupees.' JH discusses what he foresees as the results of this action. Offers suggestions for the future.
Is pleased with the new wife of son William; JH is very supportive of son John's developing interest in language [an interest of JH's]; JH has not heard of any proposed Himalayan observatory; is sending a copy of his nebula catalogue.
