with the opportunity is the exemplification consequent upon a change of name and arms by an eldest son during the lifetime of his father; but {72} this very circumstance fails to provide it, because the exemplification only follows a change of arms, and the arms being changed, there no longer exists the necessity for a mark of cadency; so that instances of the official use of a label for cadency are rare, but of such as occur I can learn of none which has received official sanction which blazons the label white. There is, however, one coat which is said to have a label argent as a charge, this is the coat of Fitz-Simon, which is quoted in Papworth, upon the authority of one of the Harleian Manuscripts, as follows: Sable, three crescents, in chief a label of two drops and in fess another of one drop argent; and the same coat of arms is recorded in a funeral entry in Ulster's Office. The label is not here termed white, and it is peculiar that we find it of another colour in another coat of Fitz-Simon (azure, a lion rampant ermine, a label of four point gules). [Illustration: FIG. 34.--Armorial bearings of Henry de Lacy, Earl of Lincoln (d. 1311): Or, a lion rampant purpure. (From his seal.)] Of other colours may be mentioned purpure (purple). This in English heraldry is a perfectly well recognised colour, and though its use is extremely rare in comparison with the others, it will be found too frequently for it to be classed as an exception. The earliest instance of this tincture which I have met with is in the coat of De Lacy (Fig. 34). The Roll of Caerlaverock speaks of his "Baniere ot de un cendall saffrin, O un lion rampant porprin," whilst MS. Cott. Calig. A. xviii. quotes the arms: "_De or, a un lion rampaund de pourpre_." The Burton coat of the well-known Shropshire family of Lingen-Burton is: Quarterly purpure and azure, a cross engrailed or between four roses argent. The Irish baronets of the name of Burton, who claimed descent from this family, bore a very similar coat, namely: Per pale azure and purpure, a cross engrailed or between four roses argent.
