Is pleased that GP's memoir has finally arrived in London [see GP's 1825-11-19]. Indicates arrangements for paying for copies. Comments on GP's astronomical observations of the last several years, and on his method of making reductions.
Regarding corrections requested by JH in a printed article. Ill health and overwork applies to him also. Pleased to hear of the work of the Optical Glass Committee. Comments on this.
Received volume on double stars by JH and James South. Followed JH's advice, ordered instruments from Germany. Asked Josef Fraunhofer to design transit instrument to fit pillars designed by Edward Troughton. Quotes Fraunhofer's response [in French] that pillars should be moved to accommodate his instrument. David Brewster anxious for JH to answer last letter.
Suggests change in JH's table of refractions. Possible error in John Pond's reductions [illustration].
