Some time ago sent a living specimen of a new species of 'Astragalus' to Sir Joseph Banks but never received any answer regarding it. Sending Smith a dwarf 'Dianthus' from Siberia, now in flower in the college garden, which he believes to be a new species, brief description of the blossoms. At the top of the letter Smith has written a Latin description under 'Dianthus hyssopifolius', and stating that in his answer he said it may be called 'Dianthus diffusus' or the preferred 'Dianthus hyssopifolius'.

Thanks Smith for his letter regarding the "little 'Dianthus'", comments on how the blossoms sometimes abruptly close at mid-day. Sending specimen and seeds of a possibly new 'Astragalus' [Smith has annotated above "only 'pilosus'"], which [George] Don had preserved for himself, a living specimen has been sent to Sir Joseph Banks but it has not been acknowledged. Gives a brief description of the leaves.

Has given [Aylmer Bourke] Lambert all the plants he collected on his travels on condition of receiving descriptions of any new species and a list of the whole, and instructions that any duplicates be sent onto Smith. Particularly anxious to know whether Smith has received all the 60 new species belonging to the Grecian collection.

Reports account given at [Sebremnitz] of ore that JH analyzed.

No summary available.

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.
