“ THE present official rules are that crests must be upon, or must issue from, a wreath (or torse) , a coronet, or a chapeau. It is not at the pleasure of the wearer to choose which he will, one or other being specified and included in the terms of the grant. If the crest have a lawful existence, one or other of them will unchangeably belong to the crest, of which it now is considered to be an integral part. In Scotland and Ireland, Lyon King of Arms and Ulster King of Arms have always been considered to have, and still retain, the right to grant crests upon a chapeau or issuing from a crest. ”
