Letter from J. Frederic Daniell, London, to Parker Cleaveland, 1824 July 28 : autograph manuscript signed.

Replying to Cleaveland's letter and saying that the Meteorological Society of London does not yet publish "directions for contemporaneous observations," but when they do, he will communicate them to Cleaveland; sending a book he has recently published on the subject of meteorology (no longer with the letter) and encouraging Cleaveland to comment on theories and speculations he has laid out in it; recommending a portable barometer made by Mr. Newman; saying that one of Newman's barometers has been sent, at the suggestion of himself and Edward Sabine, to Professor James Renwick in New York "for the purpose of communicating the standard to America & of having observations made contemporaneous with those of the Arctic expeditions which have just sailed;" discussing other instruments, including a standard therometer currently being constructed by the Royal Society; saying that, if Cleaveland would like any of these instruments, he would be happy to superintend their construction and comparison with the standards, "& any other commission of the same nature with which you may honor me."
