Is sending JH a paper on standardization of measurement, using decimalization but not the meter.

Thanks for his books. Encloses one of his own pamphlets on Atoms, which will show his personal view of mind versus matter. Comments on some of Haig's terminology.
Responds to objections published in the Times of 30 June to JH's 1864-6-18 letter to the Times regarding the introduction of the metric system in England; JH opposes this and goes on to explain the scientific basis of the British system.
Responds to WW's comments on JH's Iliad translation. Sending Book X.
Studies sidereal chromatics. Asks if William Herschel recorded colors of Beta Cygni in a 1779 observation.
Appreciates the difference between Robert Hooke's and JH's suggestions for a helioscopic telescope. Comments on these suggestions. Has recently constructed a reflecting prism. Comments on this.
Thanks for his letter and amusing pamphlet on atoms. Comments on their use of certain terms. Does not think their views differ radically. Thinks heat is a form of movement.
Corrects typographical errors in JH's recent letters [1864-6-18 & 1864-7-1] to the Times.
Sends WS William Herschel's chromatic observations of Beta Cygni. Completing 'Catalogue of Nebulae.' Works on translating Book IX of Iliad; fears he will not complete translation of Iliad.
Questions dates in William Herschel's observations. Wishes JH luck on completing translation of Iliad.
Asks again about Wilhelm Struve calculation in Outlines Astr.
Was not the person who sent him some photographs of the sun. Was glad the Astronomical Soiree was well spoken of. James Nasmyth was conspicuous and is pleased he was mentioned in JH's Outlines Astr.
Much obliged for JH applying to the Horse Guards on HM's behalf. Has now received his appointment to the 28th Regiment.
Comments on the state of JH's health; about ciphers and about decimalization.
Does not like the sound of the bronchitis. Gives a remedy that he found effective. Gives one of his own ciphers.
Comments on remedies suggested by AD [see AD's 1864-7-15]; on ciphers.
Cannot find the source of supposed Wilhelm Struve probability calculation; believes he has made a mistake. Regrets the error was not noticed in time to correct the seventh edition of Outlines Astr.
Thanks for and comments on papers on scientific history and molecular physics, particularly on a magnetic experiment and on dynamical efficiency of coal relative to motion theory of light and heat. Comments on nature of heat, 'vis viva.' Deplores laxity with which physicists use and confuse terms 'force,' 'motion,' and 'energy.'
Encloses a letter from William Simms, which contains a suggestion for JH's reflecting prism. Inclines to the view that a reflector is not the most suitable instrument for sun observations.
The [Samuel] Parlby case is a hard one. Has put JH's letter and enclosures into the hands of Reid [TM's son-in-law]. Will arrange for the case to be brought before the Governor. Arrangements are being made to erect a statue of Sir George Grey in the Botanic Garden in front of the new library and museum. Is proud of his own sailor son [John Maclear].
