I. W., also an Oxford man, is probably the writer of the prefaces to the Marquis of Worcester and to the Reader, which are signed respectively J. W. and I. W. Mr. Firth suggests that he may be J[ohn] W[illiams], son of Sir Henry Williams of Gwernevet, Brecon, who matriculated at Brasenose in 1642. I have thought that he might be Vaughan's cousin, the second John Walbeoffe (_cf._ p. 189, note), who is mentioned in Thomas Vaughan's diary (_cf. Biographical Note_, vol. ii., p. xxxviii), but there is no proof that Walbeoffe was an Oxford man. Perhaps he is the friend James to whom a poem in _Olor Iscanus_ is addressed (p. 70). P. 178. To his Learned Friend and loyal Fellow-prisoner, Thomas Powel of Cant[reff], Doctor of Divinity. On Dr. Powell, _cf._ note to p. 57. Vaughan's reason for calling him a "fellow-prisoner" is discussed in the _Biographical Note_ (vol. ii., p. xxxii). P. 181. The King Disguised. John Cleveland's poem, _The King's Disguise_, here referred to, was first published as a pamphlet on January 21, 1646. It appears in Cleveland's _Works_ (1687). The disguising was on the occasion of Charles the First's flight, on April 27, 1646, from Oxford to the Scottish camp, of which Dr. Gardiner writes (_History of the Civil War_, Ch. xli): "At three in the morning of the 27th, Charles, disguised as a servant, with his beard and hair closely trimmed, passed over Magdalen Bridge in apparent attendance upon Ashburnham and Hudson." P. 187. To Mr. M. L., upon his Reduction of the Psalms into Method. Dr. Grosart identifies M. L. with Matthew Locke, of whom Roger North says, in his _Memoirs of Music_ (4to, 1846, p. 96): "He set most of the Psalms to music in parts, for the use of some vertuoso ladyes in the city." Locke's setting of the _Psalms_ exists only in MS. A copy was in the library of Dr. E. F. Rimbault, who thinks that the author assisted Playford in his _Whole Book of Psalms_ (1677). In 1677 he died. P. 189. To the pious Memory of C[harles] W[albeoffe] Esquire.
