_Archbishop Sancroft._--It is well known that Dr. William Dillingham, Master of Emanuel College, Cambridge, published, in 1678, a volume of Latin poems, partly translations from George Herbert, partly pieces of his own, with some few added from other sources. But it is not known that most of the pieces in this volume were corrected by the hand of Archbishop Sancroft, and that one certainly was from his own pen. It occurs at p. 155. of the octavo volume alluded to, and is entitled "Hippodromus." This is a translation from an epigram by Thomas Bastard, first printed in 1598, and beginning: "I mett a courtier riding on the plaine." That it is Archbishop Sancroft's is proved from an original letter addressed to him by Dillingham in 1677, and preserved in the Bodleian. P. B. _Sir Henry Slingsby._--This gallant cavalier, who was murdered (as Lloyd says in his _Memoirs_) by Oliver Cromwell in 1658, wrote an account of the scenes in which he bore a part, from 1638 to 1648, which he called "Commentaries, containing many remarkable occurrences during the Civil Wars." Can any of your correspondents tell me where the original manuscript is to be found, and whether it was ever printed? I have seen an indifferent transcript, beginning, "The chappel at Red House was built by my father, Sir Henry Slingsby." If it has never been published, it would be an acceptable contribution to the historical memoirs of the times, and worth the attention of the Camden Society. P. B. _Origin of a Surname._--Martha Denial, widow, aged seventy-five, was buried in Ecclesfield churchyard, 3rd February, 1851. Her husband, Joseph Denial, told the parish clerk that his grandfather was found when an infant deserted in a church porch; and that he was surnamed Denial, as one whom _all deny_; and was christened Daniel, which is composed of the same letters. This is the tradition of the origin of a surname now common in this parish. A. G. Ecclesfield. _Madden's Reflections._--Madden's _Reflections and Resolutions for the Gentlemen of Ireland_. In the preface to the reprint of this work we meet with the following paragraph: "The very curious and interesting work which is {324} now reprinted, and intended for a wide and gratuitous circulation, is also of uncommon rarity: there is not a copy of it in the Library of Trinity College, or in any of the other public libraries of this city [Dublin], which have been searched on purpose. The profoundly-learned Vice-Provost, Doctor Barrett, never met with one; and many gentlemen well skilled in the literature of Ireland, who have been applied to for information on the subject, are even unacquainted with the name of the book."
