Answers CB's question on the equation. Hopes to see him in London shortly. Chemical experiments.
Has just returned from Lincolnshire. Will shortly be visiting Torquay. Would like to call on him if convenient. Has heard of a vacant professorship at Edinburgh University and may try for it. Gives an equation of W. H. Wollaston's.
Is going to Edinburgh to apply for the post left vacant by John Playfair's death. Would JH and his father give him certificates and references? [Note by Mrs. CB to the effect that her husband has heard that James Ivory will not be contesting the professorship at Edinburgh].

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.
Has been very busy; otherwise he would have answered his friendly letter earlier. Observations on tourmaline. Double refraction.
Queries regarding the refraction of light in crystals.
Answers to JB's queries on the refraction of light through crystals, and Newton's rings.
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.
