for a junior cadet, as is also any coat in which a charge or ordinary is debruised by another. Of course in more modern times no such presumption is permissible. An instance of a semé field for cadency will be found in the case of the D'Arcy arms already mentioned. Little would be gained by a long list of instances of such differences, because the most careful and systematic investigations clearly show that in early times no definite rules whatever existed as to the assumption of differences, which largely depended upon the pleasure of the bearer, and no system can be deduced which can be used to decide that the appearance of any given difference or kind of difference meant a given set of circumstances. Nor can any system be deduced which has any value for the purposes of precedent.
Certain instances are appended which will indicate the style of differencing which was in vogue, but it should be distinctly remembered that the object was not to allocate the bearer of any particular coat of arms to any specific place in the family pedigree, but merely to show that he was not the head of the house, entitled to bear the undifferenced arms, if indeed it would not be more accurate to describe these instances as simply examples of different coats of arms used by members of the same family. For it should be remembered that anciently, before the days of "black and white" illustration, prominent change of tincture was admittedly a sufficient distinction between strangers in blood. Beyond the use of the label and the bordure there does not seem to have been any recognised system of differencing until at the earliest the fifteenth century—probably any regulated system does not date much beyond the commencement of the series of Visitations.
Of the four sons of Gilles De Mailly, who bore, "Or, three mallets vert," the second, third, and fourth sons respectively made the charges "gules," "azure," and "sable." The "argent" field of the Douglas coat was in some branches converted into "ermine" as early as 1373; and the descendants of the Douglases of Dalkeith made the chief "gules" instead of "azure." A similar mode of differencing occurs in the Lyon Register in many other families. The Murrays of Culbin in the North bore a "sable" field for their arms in lieu of the more usual "azure," and there seems reason to believe that the Southern Frasers originally bore their field "sable," the change to "azure" being an alteration made by those branches who migrated northwards. An interesting series of arms is met with in the case of the differences employed by the Earls of Warwick. Waleran, Earl of Warwick (d. 1204), appears to have added to the arms of Warenne (his mother's family) "a chevron ermine." His son Henry, Earl of Warwick (d. 1229), changed the chevron to a bend, but Thomas, Earl
