Has finished his paper for JH's Admiralty Manual and it only requires copying. Can reduce it if necessary.
Sending his notes for JH's Admiralty Manual. Would have been earlier but he dislocated his left shoulder and had to have the services of an amanuensis.
Illegible.
When on board the Excellent at Portsmouth he was deafened by the firing of a gun and has since suffered from 'singing' in his ear. Can JH recommend a relief? His daughter would like an engraving of JH.
Queries regarding the statement by William Herschel on the time taken for the light from the stars to reach the earth. Have there been any new developments in this theory?
Has been applying his mode of calculation for the barometrical heights for the years 1815-23 and sent the results to the R.S.L. As JH may not see them he sends a few comments on them. Would like a suitable colleague to share his labors.
Encloses some more calculations of height by means of the barometric mean temperature. Comments on these. Staying at Ackworth until April.
Has been considering the reasons for the great depression of the barometer in November 1840. Thinks JH may be interested in the enclosed essay. Would be pleased if it could be read to the Royal Society.
Hopes his friends will support the publication of his Barometrographia, which will be exhibited at the forthcoming B.A.A.S. meeting.
Has directed the printers, Taylors, to send JH's booksellers the parts of the Barometrographia as issued, free of all costs. The science of meteorology attracts little attention at the moment.
Is grateful for his note and the book; has been ill, which accounts for the delay in his acknowledgement. The verses appear to give a good idea of the original.
Was pleased to see one of JH's letters with his mail that morning. Recalls his first meeting with JH. Has arranged for JH's name to be added to those who receive free copies of the Journal.
Has arranged for the missing parts of their journal to be forwarded. His own health is good.

Sending a letter via Ca'colia Gibson raising various queries regarding nebulae.
Sending the first volume of Kosmos. Queries regarding the Magellanic Clouds.
Would like JH's account of his own method of fixing a photograph as noted in his memoir. Singular phenomenon of the Daguerreotype. Hopes to produce a photographic paper to equal the silver plate before the month has expired. Will let him know when his process is complete.
Is grateful for the handsome manner in which JH has acknowledged RH's work. Would be willing to prepare a memoir for the R.S.L. Does Louis Daguerre's patent affect RH's manufacture of photographic papers? Has not studied the bromnets so far, but has studied the effects of bromine on plates. Comments on his results.
Sends his paper for communication to the R.S.L. Will send some more examples later as his camera has developed a defect.
Returns the photographic drawings of W. H. Fox Talbot with many thanks. Fears for their permanence. Has produced similar pictures himself acting on bromide of silver with hydrocholoric acid. Has had trouble with his periscope lens.
