ASSUMPTIVE arms, in Heraldry, are such as a person has a right to assume, with the approbation of his sovereign, and of the heralds: thus, if a person who has no right by blood, and has no coat of arms, shall captivate in any lawful war any gentleman, nobleman, or prince, he is, in that case, entitled to bear the shield of that prisoner, and enjoy it to him and his heirs for ever.
