Sending a packet. Weather and winds have been unsuitable. Will send Thomas Maclear's packet by the next vessel.
Sends a copy of the printed paper by RF. Regarding chronometer measurements. Has just received a communication from Alexander von Humboldt in which he seems to have anticipated both JH's and RF's ideas. Comments on a new machine for sounding.
Returning some papers that should have been returned earlier. Hopes all are well.
Was pleased to receive the letter and old papers. Remembers his time at the Cape with pleasure. Has been interested, but not convinced, by J. C. Ross's soundings.
Is trying to help RF understand the difference between the dynamics of solid bodies moving over each other and the dynamics of moving fluids, both water and air.
Sending some publications to show the kind of work he is doing. Has read JH's Admiralty Manual and congratulates him on its authority. Has been reading J. P. Espy's Fourth Report. Note of W. J. S. Pullen's soundings in the South Atlantic.
Comments on wind and current charts JH has received from RF.
Entirely agrees with his views on M. F. Maury. Is surprised at David Brewster's review of Maury's work. Would JH comment on RF's work on weather forecasting.
Asks for meteorological data that RF may have collected.
Asks for information about wrecks at sea and lives lost.
Tells JH he will search for the requested weather data. Encloses 'Weather Reports in the Newspaper.'
Thanks for a number of RF's writings; asks for more rainfall data to try to establish a relationship between rainfall and the solar cycle.
Reports that rainfall information is not as complete as should be. Describes available data from Meteorological Department. Thanks JH for comments on his work.
Discusses data gathering from 'the colonies.' Forwards a Scottish publication on meteorology.
Sends more data and papers on meteorological matters. Discusses weather observations by C. P. Smyth.
Thanks for all the material received; comments on some of RF's meteorological ideas.
More rainfall data.
Comments on RF's writing on drifting ice; comments extensively on RF's ideas about air circulation.
Thanks JH for his advice. Comments on various aspects of Iceland and Greenland.
