_A Cob-wall._--Why do the inhabitants of Devonshire call a wall made of tempered earth, straw, and small pebbles mixed together, a _cob-wall_? Walls so constructed require a foundation of stone or bricks, which is commonly continued to the height of about two feet from the surface of the ground. Has the term _cob_ reference to the fact that such a wall is a superstructure on the foundation of stone or brick? A. B. C. _Inscription near Chalcedon._--In 1675, when Sir Geo. Wheler and his travelling companion visited Chalcedon (as recorded in his _Voyage from Venice to Constantinople_, fol., Lond. 1682, p. 209.), it was famous only for the memory of the great council held there in A.D. 327, the twentieth of the reign of Constantine the Great: "The first thing we did (he says) was to visit the metropolitan church, where they say it was kept; but M. Nanteuil assured us that it was a mile from thence, and that he had there read an inscription that mentioneth it. Besides, it is a small obscure building, incapable to contain such an assembly." Has the inscription here spoken of been noticed by any traveller, and can any of your readers refer to a copy of it; and say whether it is cotemporary, and whether it has been more recently noticed? W. S. G. Newcastle-on-Tyne. _Domesday Book._--What does the abbreviation glđ, or gelđ, applied to terra, signify? Also, in the description of places, there is frequently a capital letter, B., or M., or S. before it, as in one case, _e. g._ "B. terr. glđ wasta." Can any one inform me what it signifies? In the case of many parishes, it is stated that there was a church there: is it considered _conclusive_ authority that there was not one, if it is not mentioned in _Domesday Book_? A. W. H. _Dotinchem._--What modern town in Holland, or elsewhere, bore or bears the name of Dotinchem, at which is dated a MS. missal I have inspected, written in the fifteenth century? The reason for believing the place to be Dutch is, that the Calendar marks the days of the principal saints of Holland with red letters. There are other indications in the Calendar of the missal having been written in and for the use of a community situated where the influence of Cologne, Liège, Maestricht, and Daventer would have been felt. Perhaps, should the above Query not be answered in England, some correspondent of your Dutch cotemporary the _Navorscher_ may have the goodness to reply to it. G. J. R. GORDON. Sidmouth. _"Mirrour to all," &c._--Can you refer me to any possessor of the poetical work entitled a _Mirrour to all who love to follow the Wars_ (_or Waves_), 4to.: London, printed by John Wolfe, 1589? A copy was sold by Mr. Rodd for six guineas. (See his Catalogue for 1846.) H. DELTA. Oxford. _Title wanted._--I have a copy of the _Pugna Porcorum_, the margin of which is covered with illustrative and parallel passages, among which is the following:
