C. _Lord Mayor not a Privy Councillor_ (Vol. iv., pp. 9. 137. 180. 236.).--The main question is, I think, settled; that there is no pretence whatsoever for the supposition that the _Lord Mayor is a Privy Councillor_; but your last correspondent DN. has fallen into a slight error, which it may be as well to correct. He confounds a _summons to the Privy Council_ with an invitation or notice which is sent (as he truly states) from the Home Office to such noblemen and gentlemen as are known to be at hand to attend at the _meeting_ for proclaiming the sovereign; but which meeting any one may, and the majority do, attend without any such notice. This is the notice that DN. received, and that I myself have received at two accessions; and which no doubt the Lord Mayor and Alderman, and city officers, also receive; but this has nothing whatsoever to do with the _Privy Council_. C. _Herschel anticipated_ (Vol. iv., p. 233.).--Thomas Wright suspected the motion of the sun in 1750; but I never heard that he was thought mad. See _Phil. Mag._, April, 1848, where an account of Wright is given. M. _Sanford's Descensus_ (Vol. iv., p. 232.).--ÆGROTUS will find the following in the Bodleian: _De descensu Domini nostri Jesu Christi ad Inferos, libri quatuor, ab Hugone Sanfordo inchoati, opera Rob. Parkeri ad umbilicum perducti_, 4to. Amst. 1611. SAXONICUS. _Pope's "honest Factor"_ (Vol. iv., pp. 6. 244.).--In the _European Magazine_ for September, 1791, under the head of "Anecdotes of the Pitt Family," there is a memoir given of Governor Pitt, from which I extract the following passages as illustrative of the Queries of your correspondents J. SWAN and C.:-- "The most extraordinary incident in this gentleman's life was, his obtaining and disposing of the celebrated diamond which is still called by his name. It was purchased by him during the time he was Governor of Fort St. George, for 48,000 pagodas, _i.e._ 20,400_l._ sterling, instead of 200,000, which the seller first asked for it. It was consigned to Sir Stephen Evance, Knt., in London, in the ship Bedford, Captain John Hudson, Commander, by a bill of lading dated March 8, 1701-2, and charged to the Captain at 6,500 pagodas only. It was reckoned the largest jewel in Europe, and weighed one hundred and twenty-seven carats. When polished it was as big as a pullet's egg. The cuttings amounted to eight or ten thousand pounds." "It appears, that the acquisition of this diamond occasioned many reflections injurious to the honour of Governor Pitt; and Mr. Pope has been thought to have had the insinuations, then floating in the world, in his mind when he wrote the following lines: "'Asleep and naked as an Indian lay, An honest factor stole a gem away: He pledg'd it to the Knight; the Knight had wit; So kept the di'mond, and the rogue was bit.'
