"LAW PROMOTION.--Mr. James Wilde has been appointed to the office of _Postman_, in the Court of Exchequer. The _Postman_ is the senior counsel without the bar attending the court, and has pre-audience of the attorney and solicitor-general in making the first motion upon the opening of the court. The _Tubman_ is the next senior counsel without the bar. The _Postman_ and _Tubman_ have particular places assigned them by the Chief Baron in open court." My Query is, from whence and at what date these two offices sprang into existence, with a list of the persons who have occupied them. And it would be as well to inquire what their duties are: for although Stephen's _Blackstone_ derives the names from the _places_ in which the individuals themselves _sit_, still the explanation hardly conveys sufficient to gather what their duties are. JOHN NURSE CHADWICK. _Second Exhumation of King Arthur's Remains._--What chronicle narrates the circumstances of the _second_ disinterment of King Arthur's bones in Glastonbury, temp. Edw. I. (A.D. 1298)? H. G. T. _Stukeley the Antiquary, and Boston._--In _Anecdotes of British Topography, &c._ (Lond. 1768), occurs the following, speaking of Boston:-- "The Churchwardens' account from 1453 to 1597, and the town-book, wrote by Mr. John Stukeley, 1676, one of his (Dr. Stukeley's) ancestors, are in the hands of the Doctor's son-in-law, Mr. Fleming." Query, into whose hands have the above records fallen? Did Stukeley leave a family? The name of "Wm. Stukeley" is appended to sundry parish records, anno 1713, at Boston. I believe he practised here for some years. THOMAS COLLIS. _Letters of Arthur Lord Balmerino._--Can any one inform me if there are any letters extant of Arthur, seventh Lord Balmerino, and where they are deposited? W. PELHAM A. Rochester. _Portrait of Thomas Percy, Earl of Northumberland._--Is any portrait known of Thomas Percy, Earl of Northumberland, who was beheaded at York, A.D. 1572, for the part he took in the "Rising in the North?" E. PEACOCK, Jr. _Newtonian System._--Is it known who was the author of a satirical pamphlet against Newton: _The Theology and Philosophy in Cicero's "Somnium Scipionis" explained_, London, 1751, 8vo.? And has an absurd story which it contains, relative to Newton, Locke, and Lord Pembroke visiting Patrick, the barometer-maker, to be shown that the mercurial vacuum was not a perfect one, ever been told elsewhere? M. _Antiquity of Vanes._--We are informed by Baron Maseres, as quoted by Lingard, that the Danes, in the last invasion by Sweyn, 1013, had vanes in the shape of birds or dragons fixed on their masts, to point out the direction of the wind. Is there any record of an earlier adoption of this method of ascertaining the way of the wind? B. B.
