Thanks for [?]'s note and enclosed sonnet. Sorry that old church was replaced during JH's absence from England.
Sending copy of first volume of HR's work on navigation [Practice of Navigation].
Thanks JH for letter introducing Mr. Burnet at the Cape. The Hudson Bay Company is recording the temperature of the subsoil at JR's request. Sends some findings, which he will publish.
Consults JH before responding to Wilhelm Weber's proposal for publication of observations. ES proposes to publish German data with data from Toronto, St. Helena, the Cape, and Van Diemen's Land. The Physical Committee of the R.S.L. suggests strengthening Adolphe Quetelet's application to the Belgian government for magnetic observations. The Hammerfest [Norway] magnetic curve does not harmonize with European ones.
Has JH any special instructions for [Louis] Agassiz's actinometers? Has sent Wilhelm Weber recent data for Toronto and St. Helena observatories while requesting Göttingen lunar observations. Discusses publication of the German Magnetic Association. Seeks advice on the inclusion of a translation of JH's paper on photometric apparatus. Has left at the R.S.L. a copy of C. F. Gauss's and Weber's magnetic atlas.
Has received papers from Colonel Sykes. Describes (and includes a portion of) Lieutenant [Henry] Yule's report on broken instruments, which have prevented operations at Aden [?]. Suggests appointing a director there. Notes safe arrival of instruments at Toronto.
Encloses letter to JH on magnetic survey in Canada and two letters from Leipzig, as well as proposals for reforms in B.A.A.S. Hopes to meet JH at the upcoming anniversary of the R.S.L.
Thanks for letting JH know about honor accorded at 'the Anniversary' [Meeting]. Offers condolences on JL's 'late severe loss.'

Has sent his communication on the comet to various observatories and the Times. Will consider candidates for medals at the next council meeting.
