Has not heard from Thomas Maclear [see GA's 1844-3-12]; has the Cape equatorial object glass been dealt with?
Has not heard from Thomas Maclear [see GA's 1844-3-12]; has the Cape equatorial object glass been dealt with?
Tells GA about a new comet becoming visible.
Asks JH for comments on GA's proposals for the Standards Commission [see JH's 1840-7-29]; GA comments on some time spent recently in Glasgow and surrounding regions.
Considers paper by [Baden] Powell to be worthless. Sent it to JH today care of Mrs. Stewart.
Asks JH's opinion about GA's plan not to print a separate volume of magnetic and meteorological observations for 1848.
Some concerns about GA's intent of attaching magnetic and meteorological observations to the R.A.S.'s Astronomical Observations [see GA's 1849-3-28].
Will reconsider the proposal about printing observations [see JH's 1849-3-29], and get back to JH.
Agenda items for next meeting of 'Committee for Superintending the Construction of Standards.' Compares English, French, Danish, and Prussian standards.
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.
Has requested of Admiralty £485 for equatorial telescope, from Merz in Munich, for Cape of Good Hope Observatory. Ask JH to estimate cost for 'next year's Estimates.'
Admiralty has approved equatorial telescope for Cape of Good Hope Observatory. Advise JH to order it from Munich.
Comments on JH's observing a 'falling star.'
Seems clear that JH's 'falling star' [see JH's 1845-4-29] was the same one reported by a correspondent of GA's as having been seen in Nottingham; in a postscript JH is not so sure.
Gives formula for defining the measure of the scale of an actinometer.
There is a need for a meeting of the Committee of Physics [R.S.L.] to discuss the current method of making temperature corrections for magnetic observations.
Detailed response to JH's 1846-10-22 about the matter of temperature corrections for magnetic observations.
Suspects that the original complainant about temperature corrections [see JH's 1846-10-22] was in fact working with a faulty magnetometer.
A committee meeting is being called [see JH's 1846-10-22].
Asks for JH's help in trying to determine the likely cost of making magnetic observations at Greenwich.
Provides information [see GA's 1840-8-13] based on equipping the Breslau Observatory; also comments on lawyers, meteor showers, and photography.
