Wishing him well for the new year. Hears JH has visited the East India College. Sends a theorem. H. P. Brougham (Baron Brougham and Vaux) amuses himself by finding the laws of central force for curves. Has been finding information on a nephew of Isaac Newton. George Stanhope (6th Earl of Chesterfield) and T. A. W. Parker (9th Earl of Macclesfield) were pupils of Abraham De Moivre.

Has not heard from him for a long time. Thought that the Government was going to turn the R.A.S. out of Somerset House. There is someone to come to the rescue of Richard Sheepshanks. Has not seen Charles Babbage for many years. Their views are incompatible. C. P. Smyth is off to Teneriffe so now is the time for JH to make suggestions. Has set up a committee to make by-laws.
