Regarding W. G. Horner's paper. Printing of their book. Is preparing a paper to submit to the R.S.L. on a mathematical subject. Will be in town shortly and will visit his laboratory. Has received more sheets of [John?] Spence's essays.

Would like comments on the accompanying paper on functional equations. Stephen Lee [of the R.S.L.] has revived the reading of Isaac Newton in Paris.
Please send the third volume of J. E. Montucla's Histoire de mathématiques. Is running into difficulties with his history of mathematics owing to lack of translations. Regarding kaleidoscopes. Has been reading David Brewster's experiments on Mother of pearl.
Thanking him for the third volume of J. E. Montucla's Histoire de mathématiques. Gives functional equations for his comments. Is afraid that he will not be able to visit Cornwall this summer.
Welcome back to London. Explain CB's demonstration of 'theorem in transcendental arithmetic.' JH's observations of 'new acid' [hyposulfurous] and optical phenomena in 'chrystals of nitre.'
Cannot meet CB in London this week. Has verified composition of [hyposulfurous] acid. Encloses crystal of 'sulpho=sulphite of lime.'
Thanks CB for his advice about applying for the post of Astronomer Royal when it becomes vacant, but does not think himself qualified. Will not be able to come to London this weekend. Regarding his new acid.
Fifth [1817] edition of Thomas Thomson's System of Chemistry shows previous discovery of JH's 'new acid,' but its reported composition is wrong.
Thanking CB for CB's further remarks on the Greenwich post. Further regarding his new acid.
Remarks on CB's article on analysis and the examples used. Hopes to see him at Christmas; then they can talk about the projected visit to Paris.
Hopes CB will visit Slough soon to discuss the proposed trip to Paris. Gives a sketch of his investigations on theorems connected with series.
Cannot accompany CB to Deptford because JH busy with James South. Mentions the 'Pearsonian dinner,' 'plagi[h]edral' crystals, and a letter by Wilhelm Olbers.
Would he please forward the letters and papers which he left behind.
Is anxious to hear how his wounds are progressing. Will not be able to come to town yet owing to various circumstances. New chemical experiments.
Made apparatus for showing rings between 'two Tourmalines.' JH's process for making hyposulfurous acid. Praises W. H. Wollaston's analysis of CB's 'Tonquinate.'
Regarding the disposal of the tourmaline. Address of his cousin. Drawing and description of the apparatus for experiments on tourmaline. Chemical experiments.
Answers CB's question on the equation. Hopes to see him in London shortly. Chemical experiments.
Sent JH's paper on mother-of-pearl and paper on hyposulfurous acid to David Brewster. Tell Brewster of JH's discovery of optical structure in crystals of bicarbonate of potash. Would Brewster accept paper from JH enlarging the definition of crystals?
Wishing CB success in his efforts to obtain the position of professor at Edinburgh. Relates details of his recent experiments with bicarbonate of potash.
JH understands CB to be a candidate for a professorial chair, and JH writes a warm letter of support.
