Is pleased that he will write articles for his Edinburgh Encyclopaedia. Would like him to write one on 'Stars.'
Sends one mathematical article on isoperimetrical problems and asks to write the article on variations as well.
There has been a delay in printing so will not require his articles until later. Will be in London in the near future and would like to see him.
Further about additional mathematical articles for the Edinburgh Encyclopaedia; comments on DB's intention to start a new 'superior' science journal.
Note to accompany the sending of some papers; JH is off to Paris.
Some additions to an article submitted about hyposulfurous acid; comments on work by J. B. Biot on polarization and double refraction of crystals.
Is anxious to receive his article on hyposulfurous acid as the volume is almost ready for the printer.
Sends a paper on mother of pearl; apologizes for confused state of paper on hyposulfurous acid.
Has heard from Charles Babbage that JH has sent him the article on hyposulfurous acid, but he has not in fact received it. Has seen Babbage a lot recently. Candidates for the Mathematical chair. Regarding colored rings in Carbonate of Potash. Has reserved his paper on Series for number 3.
Regarding refraction in various crystals and comparison with Newton's tables. Suggests a joint paper on the subject. His parcel has never arrived. Is working on a paper on rotating phenomena.
Thanks for, and comments on, DB's 1819-9-18.
Thanks for letter. Would he send his paper to [William?] Blackwood. Thinks it only fair that JH's first paper on light should be written on his own, providing he acknowledges his discoveries. Comments on recent experiments. Who has written the article on polarization in the recent Edinburgh Review?
Has received his papers on hyposulfurous acid and Mother of Pearl. Comments regarding latter. Agreement necessary on nomenclature for light. His own and J. B. Biot's experiments on light. Would JH read his paper of 1818 and comment on it.
Sends paper on deviation of tints. Comments on findings. Encloses crystals of carbonate of lime, which exhibits the system of rings. Regarding his own paper on Mother of Pearl and his indebtedness to DB. Comments on nomenclature for light.
Thanks for letters. Regarding printing of his papers. Would like to propose him Fellow of the Royal Society of Edinburgh. Biot's law. Much obliged for his opinion respecting E. L. Malus. Thanks for crystal of carbonate of lime. Comments on this.
Accepts, with thanks, DB's offer to propose JH for membership in the Royal Society of Edinburgh; some comments on DB's 1819-12-9.
Sends signed certificate for admission to Royal Society of Edinburgh; the Cambridge Philosophical Society has just been formed.
Arrangements for paying dues to the Royal Society of Edinburgh; some comments about light passing through crystals.
Clarifies areas of disagreement with DB in JH's explanation of the results of colored tints of light passing through polarizing crystals.
