A mark impressed upon certain kinds of documents to attest their authenticity and authority. Sometimes it is stamped upon wax, and attached to the paper, sometimes into the paper itself. Sealing, in this sense, is a survival of an ancient custom of inscribing important papers with cabalistic words or signs to give them a magical efficacy independent of the authority that they represent. In the British museum are preserved many ancient papers, mostly of a sacerdotal character, validated by necromantic pentagrams and other devices, frequently initial letters of words to conjure with; and in many instances these are attached in the same way that seals are appended now. As nearly every reasonless and apparently meaningless custom, rite or observance of modern times had origin in some remote utility, it is pleasing to note an example of ancient nonsense evolving in the process of ages into something really useful. Our word "sincere" is derived from sine cero, without wax, but the learned are not in agreement as to whether this refers to the absence of the cabalistic signs, or to that of the wax with which letters were formerly closed from public scrutiny. Either view of the matter will serve one in immediate need of an hypothesis. The initials L.S., commonly appended to signatures of legal documents, mean locum sigillis, the place of the seal, although the seal is no longer used - an admirable example of conservatism distinguishing Man from the beasts that perish. The words locum sigillis are humbly suggested as a suitable motto for the Pribyloff Islands whenever they shall take their place as a sovereign State of the American Union.
