More rainfall data.

Thanks JH for his advice. Comments on various aspects of Iceland and Greenland.

Speculates on gravitational effect of sun and moon on earth's atmosphere.

Making such slow progress that he fears the paper may not reach her in time, so will send a duplicate. The paper is longer than intended but it may be altered as desired. Remembers his days at the Cape with pleasure.

Sending some curious magnetic observations made at the Cape. Regarding chronometer measurements. Changes of temperature over sea and land compared.

Sending a packet. Weather and winds have been unsuitable. Will send Thomas Maclear's packet by the next vessel.

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.

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.

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.

Thanks for sending his Physical Geography. Wonders whether a rainbow could be reflected to the eye from water. Startled to read J. R. Hind's letter about the comet. Encloses a letter from a railway surveyor about an earthquake in Mendoza. This person has been responsible for the railway between Chile and Peru. Comments on the gradients and working of the line.

Is grateful for JH's views on the rainbow question. Intends to send his comments to the London Review, if he has no objections. What effects would the Comet have if it hits the Earth? Mr. Wheelwright appears to be in error on his earthquake views.

Has checked over JH's letter on rainbows and will have it signed Herschel. Encloses a scrap about rain. Mr. Wheelwright's note is curious. Will send a copy of the London Review.

Sending some reports of the Meteorological Dept. Would also like to send a wind-glass and a 'watch=aneroid' but has refrained as he knows JH is encumbered with many such things. Encloses a note from Charles Green (Rush's air pilot). Sends a few more notes for his rain collection.

Weather has been so interesting lately that he is emboldened to send the enclosed chart. Department is progressing in spite of U. J. J. Leverrier's protest. Picked up one of JH's pamphlets published at the Cape. Sends one of the Meteorological Manuals issued by the Dept.

Regarding water in the atmosphere. Effect of the moon on clouds. Some of the curiosities seen by his son while at the Embassy in Japan, including a device for giving warnings of earthquakes. Intends to show combinations of wind currents.

Further comments regarding the pressure of the atmosphere. His sketch was to demonstrate the currents of air. JH's comments on the moon were interesting.

Sending a gift of his Weather Book. Hopes JH will send his comments on chapter 18. Has scarcely seen M. F. Maury.

Enjoyed reading the dialogues of Hermogenes and Hermione [JH's 'On Atoms']. Found William Higgins's book some years ago and it appeared the basis for John Dalton's views. Finds astronomy and geology the basis for Old Testament inspiration. How absurd is the modern notion of circuits.

Book he intended to write has had to be postponed as he has been asked to prepare a second edition of his Weather Book. Sends a proof of the revision of the 18th chapter.

Sending a paper to replace the one sent previously. Comments on the effect of the moon on the atmosphere. Wrote his Weather Book in a great hurry. Regrets the expression 'lines of force' but had the approbation of several practical electricians.
