Comments on the reduction of observations, on enclosed photographs, and the health of Margaret Brodie Herschel.
GA and JH are on a committee (with Thomas Henderson) of the B.A.A.S. to supervise the reduction of N. L. Lacaille's star observations; JH encloses a draft report.
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].

A letter of introduction, asking GA to show the observatory to a Mr. Knipping from Hanover, a relative of JH's aunt Caroline.
Has passed on GA's note to Edward Sabine; cannot write more because his hand shakes too much, having just made a snow-man for the children.
Sends a letter from Humphrey Lloyd for GA's comments.

Thanks GA for his comments [see GA's 1842-1-18]; hopes that GA would be willing to have such statements, and other similar statements, made public.
Concerning Airy's papers recently submitted [see GA's 1842-1-5]. Hopes he will continue to send a report of his experiments and observations.
As many Russian observatories are now involved in magnetic observations, JH thinks the British observations should continue [see GA's 1842-1-22].
