And, in order to meet a law in heraldry, that colour is not to be placed on colour, or metal upon metal, it is directed that where the red crosses of England and Ireland come in contact with the blue ground of the flag, they are to be "Fimbriated"-that is, separated from the blue by a very narrow border of one of the metals-in this case silver, or white.

On the reverse of our beautiful bronze coins the St. George's cross on Britannia's shield is Fimbriated as it ought to be, that is, by the narrow border prescribed by the written blazon.

In this instance there was certainly no "injustice to Ireland," for the extraordinary thing is, that the St. Andrew's cross has been taken away altogether, and the saltire of Ireland, distinguished by its Fimbriated border, has been put in its place, Scotland being not now represented on the coin at all.
