[Martello Towers].—Is it the fact that the towers erected along the low coasts of Kent and Sussex during the prevalent dread of the French invasion received their designation from a town in Spain, where they were first built? By whom was the plan introduced into England? Is any account of their erection to be found in any Blue Book of the period?

[Mynyddyslwyn].—The name of the parish Mynyddyslwyn, in Monmouthshire. This name, so full of Druidic suggestion, was lost from general use at, and anterior to, the incorporation of Wales with England by the statute of Rhudolan. In a list of the names of Welsh parishes at that time, the parish is called The Parish of Tudor ab Howell. Has any reader of the "NOTES AND QUERIES" met with Mynyddyslwyn in any document bearing an earlier date?

[Bishops and their Precedence].—Bishops, in all Tables of Precedency, have place before the temporal barons. No reason is assigned but it is generally supposed to be from the respect due to the Church and their high calling which might have placed them higher.

Can any of your readers tell where any authority or reason is given by writers upon precedence why the precedence is given to them over the temporal barons?
