Desires to present methods of occultation observation to the Astronomical Society.
Much obliged for his letter. Will be glad if he would correct the press of his paper. Encloses a printed sheet, which may amuse him.
Has too long delayed thanking him for his works. Sends some memoirs of Edward Sabine, etc. Comments on work that needs doing.
Sending this note to inform JH that he began his own serpentine paper on Friday and next Friday intends to read JH's paper on Predazzo. Would like to go over the paper with JH beforehand. Intends to publish his own paper in Brewster's Journal. Can JH meet CL here Wednesday morning?
Believes that JH is acquainted with R. I. Murchison, who is to accompany CL to see the works of M. I./I. K. Brunel's Thames tunnel, after they have gone through JH's paper. Would JH like to accompany them?
Is preparing a paper on planetary perturbations, which GP would like to send to the Astronomical Society for publication. Comments on JH's ideas on the subject of perturbations. Would the paper being in French be a problem? Comments on Henry Kater's method for finding the zero point in his meridian circle.
Not upset that JH withdrew WR's paper on photometer from R.S.L. Sent similar paper to David Brewster's [Edinburgh Journal of Science] with note on JH's method for finding relative heating power of solar rays. Wants to dedicate WR's book on light and heat to JH.
Announces 2 June meeting of 'Commissioners for more effectually discovering the Longitude at Sea.' Inquired about 'excise,' but sees no reason to wait for Navy Board to act.
Rearranges a meeting of [the R. S. L.'s Glass Committee] to take place at the Pellat and Green's Glass House in Holland St.
Read your proposal on experiments at Teneriffe to the R.S.L. Council, which declined to make 'an especial recommendation' in support of them to the government.
Acknowledges receipt of WS's second volume of observations and the new telescope's results. Mentions Caroline Herschel's catalogue of nebulae.
The Duke of Cambridge inquired about JH's research interests.
Compliments JH on work as Secretary of the Astronomical Society and for keeping the scientists of Europe informed of discoveries made in England. Finds that GS needs permission from Italian government to be a member of the R.S.L.; expects this will not be difficult.
