Reports account given at [Sebremnitz] of ore that JH analyzed.
Chemical experiments with EC's blowpipe. Discovered cause of blowpipe explosions. Thank Mrs. Lowry for carbon substance sent to EC. Sent metal of Baryta to W. H. Wollaston. Suspects metallic nature of carbon and diamond.
Regrets his blunder. Send him Wilson Lowry's address and he will write. His own recent experiments with platinum.
When his lectures have finished he will attend to JH's request regarding the inscription of Dr. G. H. Noehden. Hopes he will attend one of Sir Joseph Banks' Sunday evening gatherings and show the specimens he has given JH; also show them to W. H. Wollaston.
Forgot to mention it last time they were together that another mammoth has been found at Trumpington. This agrees with G. C. L. D. Cuvier's theories. Regarding the ore JH has just analyzed.
Thanks for his kind note. Mr. Harrison wishes him to prepare a paper for the R.S.L. Will find his experiments continued in the next number of Thomson's Annals. As soon as his blow pipe is repaired he will let him know.
Mentions some chemical experiments on which JH has worked; hopes EC will exhibit his experiments for R.S.L.
Describes chemical experiments carried out by JH on corundum. Attempts to interpret these experiments.
Praises EC for 'amazing experiments' published in [William T.] Brande's journal [Quarterly Journal of Science and Art]. Wishes EC's publication had appeared in R.S.P.T. Has an experiment to show EC.
Thanks EC for his interest in a paper JH submitted to the Geological Society. JH has come to question some of his observations and to recognize that J. J. Berzelius anticipated JH's recognition of the acid nature of silica.
Reports on some chemical results obtained by JH.
Sending EC a specimen that W. H. Wollaston describes as 'the most intractable substance by fire' he has ever seen. Discusses its properties and possible chemical composition.
Returns with thanks EC's specimen of Island Crystal. Also discusses specimen of titanium lent by EC.
