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.
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.
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.
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.
Comments on the report [see GA's 1841-8-11]; wants the standards legislation to be demanding of rigor in application.
Comments specifically on the accuracy of surveyors' chains [see JH's 1841-8-13], together with brief comments on a few other matters.
Further comments on the Standards Commission Report [see GA's 1841-7-27].
Is fully occupied reducing Cape observations, and is producing a star list by magnitudes, resulting in some interesting anomalies.
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.
