Encloses catalogue of 1677 stars. Has sent his own report on star nomenclature to Plymouth. Will call at his house later in the week.
Hears with pleasure of the peace reigning at the Cape between the Caffres. The Boers are a different proposition and JH agrees with GN's policy. J. R. Innes called in on his way to Scotland. Weather in England is gloomy, like the political events.
Requests JH's opinion on five specific points in 'Report on Standards.'
Presents best wishes to Lady Herschel. Regrets not having met on account of meeting with [G. B.] Airy at Greenwich. Is keeping four pictures of JH and has offered 2 additional ones to Prince Albert.
Asks for JH's comments on George Peacock's assessment that the Report of the Standards Commission [see GA's 1841-7-27] is directed too much to scientific men, and others will not understand it; suggests an appendix to show the relationship between the proposed measures.
Reliability of measuring instruments used in scientific and public surveys. Approves George Peacock's suggestion to revise survey tables for use by non-scientist surveyors. Schools should teach only legalized systems of weights, measures, and money.
Comments on the report [see GA's 1841-8-11]; wants the standards legislation to be demanding of rigor in application.
Has received JH's 'Report' proof regarding JH's description of specific gravity. Captive balloons. Would JH refer him to D. F. J. Arago's experiments on the shadow of a disk.
Is confused by French system of recording specific gravity and seeks GA's assistance; also GA and JH are named to a committee that JH thinks only wastes money.
Complains further about French specific gravity designation [see JH's 1841-8-14 or earlier], and describes observing colored fringes on the edge of clouds.
Discusses meteor showers of 9 August 1840, emanating from a point in the constellation Perseus. Calls attention to a report on these meteors as seen from near Vesuvius in 1779 by William Hamilton.
Comments specifically on the accuracy of surveyors' chains [see JH's 1841-8-13], together with brief comments on a few other matters.
Is fully occupied reducing Cape observations, and is producing a star list by magnitudes, resulting in some interesting anomalies.
Outlines suggestions from [Drinkwater-]Bethune for improving 'Report of Standards.' Bethune distinguished Exchequer, Local, and Parliamentary (or National) standards, and preserved unit called 'land chain' equal to twenty yards.
Thinks that there should be more definite instructions for the Directors of the Magnetical Observatories. Has drawn up a paper, which if JH agrees with, can be signed and printed for distribution. Points out the significant parts. There should be a common nomenclature for the weather.
Further comments on the Standards Commission Report [see GA's 1841-7-27].
Replies to [?]'s questions about 'Mr. Bethune's suggestions' concerning terminology to be used for standards of weight and measure. Agrees with G. B. Airy that term 'land' should be used with 'land chain' unit.
