_St. Hibbald._--Who was St. Hibbald, and where is some account of him to be found? He is reported to have been buried at Hibbaldstowe, near Kirton, in Lindsey. K. P. D. E. Minor Queries Answered. _Unde derivatur "Gooseberry Fool?"_--I have heard some wild guesses on this subject; the most preposterous, perhaps, being that which would connect the term with gooseberry _food_. Has not the French word _fouler_, "to press," or "squeeze," something to do with the matter? T. J. T. Cheltenham, May 6. 1851. [Our correspondent will find ample confirmation of the accuracy of his derivation in Tarver's _Phraseological Dictionary_, where, under _Fouler_, he will find the examples, "_Fouler des pommes, du raisin_, to press, to crush, to squeeze apples, grapes."] _Biography of Bishop Hurd._--The longest biographical sketch I remember to have seen of the late Bishop Hurd, the friend and biographer of Bishop Warburton, was in a work called the _Ecclesiastical Register_, or some such name, I suppose of the date of 1809 or thereabouts. Can any correspondent of "NOTES AND QUERIES" direct me to the precise title and date of the work, or point out any better sketch of the Bishop's life? F. K. [In the collected Works of Bishop Hurd, 8 vols. 8vo., edit. 1811, will be found an autobiographical sketch of the Bishop, entitled "Some Occurrences in my Life," discovered among his papers after his decease. Nichols' _Literary Anecdotes of the Eighteenth Century_, vol. vi. pp. 468-512., contains a long and interesting account of the Bishop. See also the _Annual Register_, vol. 1. p. 155.] _Friday, why considered unlucky._--Can any of your readers tell me why Friday is considered an unlucky day? E. N. W. [There is no doubt the belief of Friday being an unlucky day originated in its being the day of the Crucifixion. A very early allusion to this superstition, and which has not we believe been recorded by Brande, will be found in Geoffrey de Vinsauf's "Lament for Richard Coeur de Lion," who was killed on a Friday: "O Veneris lacrymosa dies, O sidus amarum! Illa dies tua nox fuit, et Venus illa venenum." It is to this passage Chaucer refers in his _Nonnes_ Preeste's Tale, v. 15, 353., _et seq._, when he says: "O Gaufride, dere maister soverain, That, whan thy worthy King Richard was slain With shot, complainedest his deth so sore, Why ne had I now thy science and thy lore, The Friday for to chiden, as did ye? For on a Friday sothly slain was he."] _The Lord Mayor a Privy Councillor._--Can any of your contributors inform me whether the prefix "Right Honourable" is accorded to the title of the Lord Mayor of London as a mere matter of courtesy, or whether our Chief Magistrate is for the time being _ex officio_ a Privy Councillor, and consequently "Right Honourable?" If any authority for either position can be cited, so much the more satisfactory. LEGALIS.
