Fac

If a Fac or Flowered letter be deeper than the Composing-stick we measure the exact width of it by Quotations, or common Quadrats; which we put into our Stick, and the Fac into the Galley, and then compose, and empty each time so many lines as our measure in the Stick will allow, till we have composed so many as reach something beyond the Depth of the Fac, that by justifying it up to the lines, its touching the letters underneath may be prevented.
