shorthand

There is a Notion prevails among many People, to yͤ prejudice of all kinds of Short-hand; which is this. That when a Person sets down a Memorandum in his pocket Book in Short-hand, it is lost, in caſe of Death or any other accident, to yͤ rest of yͤ World, though it may contain things of great Consequence to other People. … I affirm, … that if any Person makes use of my long Short hand, which he will certainly do, in caſe he deſigns that what he writes should be read by another Person, it will be as legible to any one acquainted with this Art, as if it was writ in Round Hand.

The jargon becomes a shorthand for these advanced concepts.
