Approves of the plan for the observatory. Comments on some of the features. Good equatorial is a necessity. Will try to obtain a copy of the plan of the Cambridge Observatory.
Has sent money for Robert Molyneux clock care of Friess, the bankers. Is grateful for JH's trouble over the clock. Do not print certain observations he sent as they form the subject of an argument with F. X. von Zach.
[Repetition of information in JL's 1823-11-17 and JL's 1824-2-10.]
Has just returned from abroad and found his letter of April awaiting him. Hoped to visit Vienna when abroad. Has received money for the clock. Hopes to send his own paper on double stars later. Encloses some papers for distribution. Measured height of Etna when in Italy. Met Josef Fraunhofer and had an instructive discussion with him.
Receipt and shipment of various papers and letters. Robert Molyneux has not received payment for clock. JH ordered another for L. A. Fallon; it is ready to ship. Clarifies Edward Sabine's remark about pendulums. Hopes to translate JL's Analytical Geometry. JH translated JL's 'empirical formula of refraction.' Believes JL's method of determining latitude without knowing the time is not new. Notes J. W. A. Pfaff's translation of William Herschel's works.
