Anticipates appearance of JH's work on double stars; asks for suggestions for employment for a young man from Germany, and offers some suggestions about refining the study of refraction.
About books and papers, being sent both ways.
Bad weather has prevented him from observing the transit of the comet. Has purchased a refractor similar to the one at Dorpat.
About observing comets, problems with book sellers and shipping books. JL has written a popular astronomy in which he deals with perturbations, precession, and other difficult topics. Would JH like a copy?
Sends some additions to an earlier paper on object glasses of telescopes; also some observations of the August comet, made by other astronomers.
Thanks for comments on JL's papers [see JH's 1828-7-24]; Charles Babbage had visited JL.
Is sending papers for the Astronomical Society Memoirs, on telescope lenses and the construction of telescopes, planetary observations, and the use of equatorial telescopes. Is anxious to see JH's writings on light and his nebulae catalogue.
