The equatorial on the Dublin Observatory dome needs improvement. In the last fifty-two months, WH has seen three new planets: Neptune, Iris, and Flora.
WH notes that quaternions derive some interesting results in problems with three moving bodies.
Asks JH about calculations of arcs of meridian.
As disturbed about the medal situation as JH [see JH's 1847-2-8]; the solution seems to be to award two medals.
Reports to JH on the discussion, about the medal problem, at an R.A.S. meeting [see JH's 1847-2-11].
Sends angular results from various astronomers using similar epoches.
More information on the activity of the R.A.S. in trying to resolve the medal problem [see GA's 1847-2-13].
W. S. Jacob sends Alpha Centauri observations to R.A.S.; uses JH's Cape Results as a guide to double stars.
Thanks JH for suggestion on his method of Great Circle sailing. Further enquires over some cartographic matters.
Asks JH to suggest candidates for a professorship at the South African College.
Asks if JH observed Gamma Scorpii as a double star; sends observations of it from W. S. Jacob in India. W. S. Jacob observes Neptune.
Studies two possible orbits of Gamma Virginis; sends complete descriptions of both, including calculation of the apparent and actual ellipse. The first orbit combines the data of other astronomers.
Sends papers to JH as president of the RAS.
Thanks JH for Gamma Scorpii observations. Plans to have Edinburgh Observatory record observations of 2-3000 stars over 30 years. Edinburgh observations for 1841 published.
Discusses whether John Couch Adams should receive the Copley Medal for his work in the attempted discovery of Neptune.
Accepting JH's invitation to spend a few days with him. Remarks on planets in general. Information on academic success of Hugh Percy (3rd Duke of Northumberland).
Thanking him for his hospitality.
Relating to the appointment of Langham Dale to the staff of the South African College.
Sends extracts of a letter from H. C. Schumacher. Does not agree with Schumacher regarding F. W. Bessel's 'specific attraction.'
Regarding W. S. Stratford and the printing of the catalogues. F. W. Bessel's star corrections.
