_Sir Thomas Herbert's Memoirs of Charles I._ (Vol. iii., p. 157.).--My friend, who is in possession of the original MS. of this work, is desirous of ascertaining whether the volume published in 1702 be a complete and exact copy of it. I will transcribe the commencing and concluding passages of the MS., and shall be obliged if MR. BOLTON CORNEY will compare them with the book in his possession, and tell me the result. "S^r, "By your's of the 22d of August last, I find you have receaved my former letters of the first and thirteenth of May, 1678; and seeing 'tis your further desire," &c. "This briefe narrative shall conclude with the king's owne excellent expression: _Crowns and kingdoms are not so valuable as my honour and reputation--those must have a period with my life; but these survive to a glorious kind of immortality when I am dead and gone: a good name being the embalming of princes, and a sweet consecrating of them to an eternity of love and gratitude amongst posterity._" The present owner of the MS. has an idea that an incorrect copy was fraudulently obtained and published about 1813. Is there any foundation for this supposition? ALFRED GATTY. Ecclesfield. _Comets._--Where may a correct list of the several comets and eclipses, visible in France or England, which appeared, or took place, between the years 1066 and 1600, be obtained? S. P. O. R. {224} _Natural Daughter of James II._--James II., in _Souverains du Monde_ (4 vols. 1722), is stated to have had a natural daughter, who in 1706 was married to the Duke of Buckingham. Can any of your readers inform me the name of this daughter, and of her mother? Also the dates of her birth and death, and the name of her husband, and of any children? F. B. RELTON. _Going the Whole Hog._--What is the origin of the expression "going the whole hog?" Did it take its rise from Cowper's fable, _the Love of the World reproved_, in which it is shown how "Mahometans eat up the hog?" [Sigma]. _Innocent Convicts._--Can any of your readers furnish a tolerably complete list of persons convicted and executed in England, for crimes of which it afterwards appeared they were innocent? [Sigma]. _The San Grail._--Can any one learned in ecclesiastical story say what are the authorities for the story that King Arthur sent his knights through many lands in quest of the _sacred vessel_ used by our Blessed Lord at His "Last Supper," and explain why this chalice was called the "Holy Grail" or "Grayle?" Tennyson has a short poem on the knightly search after it, called "Sir Galahad." And in Spenser's _Faerie Queene_, book ii. cant. x. 53., allusion is made to the legend that "Joseph of Arimathy brought it to Britain." W. M. K.
