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.

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.

Is fully occupied reducing Cape observations, and is producing a star list by magnitudes, resulting in some interesting anomalies.

Further comments on the Standards Commission Report [see GA's 1841-7-27].
