Hopes to have JH's catalogue for the first meeting of the R.A.S. Anything about the comet would be welcome. Regarding one of Franciscus Vièta's mathematical theories.

Has received the catalogue and it will be sent to the press. Is grateful for JH's offers. Does he know anything of Bullialdi's (Ismael Boulliau) Astronomica philolaica? Refers to Franciscus Vièta's Harmonicum coeleste. 25 copies of JH's latest paper has been forwarded.

Has visited Caroline Herschel, who is well. Discusses whether JH will make magnetic observations at the Cape of Good Hope.

Is sending JH some writings by Mr. (Mrs.?) Thomas Malthus on idiotic people and a book by WW [Astronomy and General Physics]. Mentions Richard Jones. Asks whether WW has seen 'the comet.'

Has postponed answering his letter until he has some worthwhile results to transmit. Local savants are unwilling to take much trouble but has met a German meteorologist, L. F. Kämtz, and together they have carried out observations on some of the mountains. Encloses some of the actinometer readings. Has 80 series of magnetic observations.
