CD thinks report of a rock imbedded in an iceberg is remarkable; wants to write a note for the [Journal] about it. Asks for location of the sighting and a chart of the Antarctic Sea. [See "Rock seen on an iceberg", Collected papers 1: 137–9.]
Thanks for observations; comments on one of his own observations; notes imminent move to Collingwood and birth of seventh child.
Just received RP's Dec. 1837 observations, forwarded from Cape of Good Hope. JH is now president of R.S.L. joint committee of Physics and Meteorology. Meteor shower of 10 Aug. 1839. Describes global magnetic survey conducted on Göttingen Mean Time. Hopes U.S. will join survey. [Enclosure: Printed notice of global magnetic survey, listing participating governments, purposes, and instruments.]
Received the enclosed in August from Teodoro Monticelli but did not know how to forward it to JH. Would he return the letter when finished with.

Speaks of arrangements for magnetic observatories in India, in the Himalayas, and at Bombay. Discusses the locations and buildings of the sites. Wishes to add Singapore as an observatory station.
Americans plan to investigate laws of North American storms. U.S. government should apply to British if cooperation is desired. Thanks JH for letter recommending ES for royal medal. Hopes someone will work on scientific data collected by different governments.

Encloses a letter from Alexander von Humboldt to Lord Minto endorsing the idea of an international magnetic survey. Stresses the value of the letter.

Claims the name 'meteorological committee' is misleading for a R.S.L. committee that handles all branches of observational physics. Suggests that physics be divided into 'Experimental and Terrestrial.'
