Summary:

John Lubbock entitled to bring his proposal before R.A.S., and to the best advice they can give, but the idea of explaining new views on physical astronomy strikes RS as 'objectionable' in principle. No one will understand his presentation. How to proceed with this. RS's work on the standard yard.

Summary:

Thanks for JH's reply about 'Towson Tables.' Please return copy of JH's letter to FB. Encloses Georg Merz's account. [Telescope] is at Custom House awaiting shipment to Cape of Good Hope. Does JH have plan and estimate yet for dome, so FB can present it to Admiralty? Received JH's 24 Oct. note about Mr. Morris's account.

Summary:

John Lubbock wishes only to explain his system, so there is no reason why the R.A.S. should not listen to him. Certain conditions must be met. Troubles with the R.A.S.M.N.

Summary:

Sends Principles of Natural Philosophy from the Swedenborg Association. Published nearly one century earlier, its contents should interest JH. Contains a nebular theory commonly attributed to [P. S.] Laplace.

Congratulations on finishing his paper. Would he check over the proofs. Richard Jones is well, though not well enough to attend at the College chapel. J. E. D. Bethune and John Lefevre are staying with Jones. Bethune starts for India in February.

Summary:

Destroy all HW's letters claiming errors in Leonhard Euler's values for Bernoulli's numbers. Mr. Hensley of Trinity College found weakness in HW's continued subtraction method. Clarifies symbols HW used to represent P. S. Laplace's expressions of Bernoulli's numbers.

Summary:

Verified Leonhard Euler's values for Bernoulli's numbers up to B=25 by method previously outlined and to be stated fully in this letter. Mr. Hensley [of Trinity College] proposes to revise incorrect values given in Penny Cyclopaedia. Computing a Bernoulli number by P. S. Laplace's formula takes three days. HW's method of continued subtraction requires only 24 hours.
