_Mynyddyslwyn_.--The name of the parish Mynyddyslwyn, in Monmouthshire. This name, so full of Druidic suggestion, was lost from general use at, and anterior to, the incorporation of Wales with England by the statute of Rhudolan. In a list of the names of Welsh parishes at that time, the parish is called _The Parish of Tudor ab Howell_. Has any reader of the "NOTES AND QUERIES" met with Mynyddyslwyn in any document bearing an earlier date? D. RHYS STEPHEN. Abergwyddon. _Three Dukes_.--Who were the three Dukes who killed the beadle on Sunday morning, 26th February, 1671, as commemorated by verses in _Poems on State Affairs_, vol. i. p. 147.? E. _Bishops and their Precedence_.--Bishops, in all Tables of Precedency, have place before the temporal barons. No reason is assigned but it is generally supposed to be from the respect due to{10} the Church and their high calling which might have placed them higher. Can any of your readers tell where any _authority_ or _reason_ is given by writers upon precedence why the precedence is given to them over the temporal barons? E. _Guineas_.--What is the earliest instance of the use of the word _guinea_ as a name for a coin? The common story is, that the piece of twenty-one shillings was so called in the reign of Charles II. from being made of gold from Guinea. What coin is meant in the following receipt?-- "Sachent tous que Mons. Gualhard de Dureffourt ... ad recue ... quatorze _guianois_ dour et dys sondz de la mon[oye] currant a Burdeux." The date is 12. Nov. 1387. The document is quoted in Madox's _Baronia Anglica_, p. 159. note _d_. A.J.H. _Parish Registers Tax_.--In the Parish Register of Wigston Magna, Leicestershire, are the following entries against several dates in the Baptisms and Burials:-- 1784. Septr. 5th (Burials), "P'd Tax to y's Day." ---- Novr. 28th (Baptisms), "p'd Tax." 1785. Octr. 14th (Baptisms), "p'd Tax to this Day." 1786. Septr. 12th (Christenings), "p'd tax to this Day." 1786.

I should be glad to be informed what tax is here referred to. These are all the entries of the kind. ARUN. _Charade_.--Can any of your readers help me to a solution of the following poetical charade, which I believe appeared in the _Times_ newspaper a few years back with this heading to it:-- "The following piece of mysticism has been sent to us as original, with a request for a solution. The authorship is among the secrets of literature: it is said to have been by Fox, Sheridan, Gregory, Psalmenazar, Lord Byron, and the Wandering Jew. We leave the question to our erudite readers."
