Further about additional mathematical articles for the Edinburgh Encyclopaedia; comments on DB's intention to start a new 'superior' science journal.
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.
Sends JM material for inclusion in Mathematical Essays by the Late William Spence, Esq., ed. by JH. [Includes manuscript of final paragraph of JH's Preface to this book.]
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.
Acknowledges in JH's father's name FB's notice of the upcoming annular eclipse of 1820. Stresses the importance of observing it.
Mr. Murray will bring to DB two papers by JH, one on hyposulfurous acid and one on mathematical analysis, plus requested abstract of JH's and William Herschel's 'last papers' in R.S.P.T.
Note to accompany the sending of some papers; JH is off to Paris.
JH arrived safely yesterday and attended event at home of Sir Joseph Banks. Dr. [Matthew] Baillie asked about Lady Mary Herschel. JH and Charles Babbage, preparing to tour France, leave tomorrow for Dover. Wishes better health for MH and William Herschel.
Will sail tomorrow for Calais. Could not find Mr. Armstrong in Dover.
Arrival in France. Travel companions. JH and Charles Babbage will go to Institute tomorrow to visit J. B. Biot, S. D. Poisson, and other mathematicians.
JH's father and mother will call on WW during visit to Bath, scheduled after wedding of JH's cousin. Spent three weeks meeting science luminaries in Paris. Notes continuity of scientific endeavors there over three generations.
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.
