Thanks ES for his paper. Sun spot activity should increase in 1857. Discusses his own earlier ideas concerning relationship between sun spots and Aurora Borealis.
Glad to know which of ES's papers JH has. Sends another along with maps from [Keith] Johnson's Physical Atlas. Discusses JH's ideas regarding relationship between solar spots and magnetic disturbances.
Mentions [P.] Plantamour's memoir on barometer and a criticism by Mr. Dilams[?]. Comprehending why variations of magnetic disturbances correspond in period with terrestrial year is difficult.
Discusses advantages of different magnetic charts. Grateful for [P.] Plantamour's observations. Satisfied with [J. R.] Wolf's period of 11.11 years for solar spots.
Thanks JH for critiquing her paper during his illness. MS's On the Connexion of the Physical Sciences is to be published in translation at Cesna.

Reading proofs of JH's Essays Q. E. R.; working on an article on meteorology.
Sending a little joke on a political theme. Further regarding a query of JH's on a rabbit. Gives a problem on a polygon. Meteorology is peculiar as weather does not appear to be governed by any laws.
