_Coleridge and the Penny Post_ (Vol. iii., p. 6.).--Mr. Venables asks a question in a way that may lead the reader to infer an answer, and an ungenerous answer; and he calls on Mr. Hill to give him satisfaction, as if Mr. Hill had nothing better to do than to inform Mr. Venables, and correct Miss Martineau's blunders. If Mr. Venables had taken an active part in bringing about the greatest moral movement of our age, he would have known that, amongst the hundred other illustrations adduced by Mr. Hill, was the very anecdote to which he refers; and that Mr. Hill quoted it, not once or twice, but dozens of times, and circulated it, with Coleridge's name, over the whole length and breadth of the three kingdoms, by tens of thousands of printed papers. Mr. Hill has not had a tithe of the honour he deserves--and never will have--and I cannot remain silent, and see his character questioned, though in matters too trifling, I think, even to have occupied a corner in "NOTES AND QUERIES." C.W.D. _The Autograph of Titus Oates_ (Vol. ii., p. 464.).--It may be seen in the Library of St. John's College, Cambridge. It is written at the end of every chapter in "_A Confession of Faith, put forth by the Elders and Brethren of many Congregations of Christians (baptized upon profession of Faith) in London and the Country_." 12mo. Lond. 1688. J.R. Cambridge. _Circulation of the Blood_ (Vol. ii., p. 475.).--The passage in Venerable Bede referred to by J.MN. may have been in a tract _De Minutione Sanguinis sive de Phlebotomia_; (which occurs in the folio editions, Basle, vol. i. p. 472.; Colon., vol. i. p. 898.). In the enumeration of the veins from which blood may be taken, he says,-- "De brachio tres, _qui per totum corpus reddunt sanguinem_, capitanea linea, matricia, capsale." The subject of bleeding is again referred to in _Eccl. Hist._, vol. iii, but not to the purpose. J. EASTWOOD. Ecclesfield. _True Blue_ (Vol. ii., p. 494.).--From documents relative to the wars of the Scottish Covenanters, in the seventeenth century, it appears that they assumed _blue ribbons_ as their colours, and wore them as scarfs, or in bunches fastened to their _blue bonnets_ and that the border English nicknamed them "_blue caps_" and "jockies." Hence the phrase, "True blue Presbyterian." G.F.G. _Cherubim and Seraphim._--Why are the cherubim represented as a human head, with the wings of a bird? And why have the seraphim no bodily representation? What, in fact, is the supposed distinction between them? OMEGA. [Our correspondent will find much curious information on this subject, accompanied by some exquisite woodcuts, in Mrs. Jameson's _Poetry of Sacred and Legendary Art_.]
