_Liber Conformitatum, &c._ (Vol. v., p. 202.).--On the _Liber Conformitatum_, I confidently assert, from accurate inquiry, that no edition preceded that of 1510, nor is there any authority for the alleged one of Venice. A long account of this most disedifying volume will be found in DeBure's _Bibliographie Instructive_, No. 4540. I am in possession of the second edition in 1511, perfectly identical in the text. Its absurdity is equal to its obvious, though not intended, blasphemy; for it is written in genuine simplicity of design. I have likewise the _Alcorand des Cordeliers_, with the second book by Conrad Badius, the son of Jodocus Badius Ascencius, a native of Belgium, but one of the early Parisian printers, and author himself of various works. The title of my edition of the _Alcoran_, printed at Geneva, 1575, differs from that of 1586, but necessarily of the same import, and quite as prolix. J. R. Cork. _Grimesdyke; Grimes Graves_ (Vol. v., p. 231.).--As J. F. F. has repeated Blomefield's account of these curious pits (commonly known as _Grimes Graves_, in Weeting parish, Norfolk), it is right to add some more recent information respecting them. An investigation was made there last month, by digging a trench through the middle of a pit, and at the depth of about three feet an oval fire-place of flints was discovered, containing numerous bones of oxen, &c. One of the smaller pits was then similarly treated, and we found the same proofs of habitation. No stone implements were discovered, but further researches may bring some to light. Blomefield's statement that it is a Danish camp is quite without foundation, and his "form of a quincunx," in which he supposed the pits to be, could have existed only in his own imagination, stimulated by the learned labours of Sir Thomas Browne. There can be no doubt now that they were dwellings of the British, similar to the pits on the coast at Weybourne. That _Grime_ was a Danish leader, "Præpositus," &c., is also open to doubt. When so many British earthworks are designated by this name, what is more likely than that the Saxons, not knowing whose hands had erected them, superstitiously ascribed them to the _grim_ spirit, the Devil?--whence _Grimsdyke_, the Devil's ditch, &c. Neither this opinion, however, nor Mr. Guest's (a "boundary") seems applicable to a Hundred, as _Grimeshoo_, unless as being so full of Grime's operations. C. R. M.
